A Chronicle of Timekeeping
Our conception of time depends on the way we measure it
A According to archaeological evidence, at least 5,000 years ago, and long before the advent of the Roman Empire, the Babylonians began to measure time, introducing calendars to co-ordinate communal activities, to plan the shipment of goods and, in particular, to regulate planting and harvesting. They based their calendars on three natural cycles: the solar day, marked by the successive periods of light and darkness as the earth rotates on its axis; the lunar month, following the phases of the moon as it orbits the earth; and the solar year, defined by the changing seasons that accompany our planet's revolution around the sun.
B Before the invention of artificial light, the moon had greater social impact. And, for those living near the equator in particular, its waxing and waning was more conspicuous than the passing of the seasons. Hence, the calendars that were developed at the lower latitudes were influenced more by the lunar cycle than by the solar year. In more northern climes, however, where seasonal agriculture was practised, the solar year became more crucial. As the Roman Empire expanded northward, it organised its activity chart for the most part around the solar year.
C Centuries before the Roman Empire, the Egyptians had formulated a municipal calendar having 12 months of 30 days, with five days added to approximate the solar year. Each period of ten days was marked by the appearance of special groups of stars called decans. At the rise of the star Sirius just before sunrise, which occurred around the all-important annual flooding of the Nile, 12 decans could be seen spanning the heavens. The cosmic significance the Egyptians placed in the 12 decans led them to develop a system in which each interval of darkness (and later, each interval of daylight) was divided into a dozen equal parts. These periods became known as temporal hours because their duration varied according to the changing length of days and nights with the passing of the seasons. Summer hours were long, winter ones short; only at the spring and autumn equinoxes were the hours of daylight and darkness equal. Temporal hours, which were first adopted by the Greeks and then the Romans, who disseminated them through Europe, remained in use for more than 2,500 years.
D In order to track temporal hours during the day, inventors created sundials, which indicate time by the length or direction of the sun's shadow. The sundial's counterpart, the water clock, was designed to measure temporal hours at night. One of the first water clocks was a basin with a small hole near the bottom through which the water dripped out. The falling water level denoted the passing hour as it dipped below hour lines inscribed on the inner surface. Although these devices performed satisfactorily around the Mediterranean, they could not always be depended on in the cloudy and often freezing weather of northern Europe.
E The advent of the mechanical clock meant that although it could be adjusted to maintain temporal hours, it was naturally suited to keeping equal ones. With these, however, arose the question of when to begin counting, and so, in the early 14th century, a number of systems evolved. The schemes that divided the day into 24 equal parts varied according to the start of the count: Italian hours began at sunset, Babylonian hours at sunrise, astronomical hours at midday and 'great clock' hours, used for some large public clocks in Germany, at midnight. Eventually these were superseded by 'small clock', or French, hours, which split the day into two 12-hour periods commencing at midnight.
F The earliest recorded weight-driven mechanical clock was built in 1283 in Bedfordshire in England. The revolutionary aspect of this new timekeeper was neither the descending weight that provided its motive force nor the gear wheels (which had been around for at least 1,300 years) that transferred the power; it was the part called the escapement. In the early 1400s came the invention of the coiled spring or fusee which maintained constant force to the gear wheels of the timekeeper despite the changing tension of its mainspring. By the 16th century, a pendulum clock had been devised, but the pendulum swung in a large arc and thus was not very efficient.
G To address this, a variation on the original escapement was invented in 1670, in England. It was called the anchor escapement, which was a lever-based device shaped like a ship's anchor. The motion of a pendulum rocks this device so that it catches and then releases each tooth of the escape wheel, in turn allowing it to turn a precise amount. Unlike the original form used in early pendulum clocks, the anchor escapement permitted the pendulum to travel in a very small arc. Moreover, this invention allowed the use of a long pendulum which could beat once a second and thus led to the development of a new floor-standing case design, which became known as the grandfather clock.
H Today, highly accurate timekeeping instruments set the beat for most electronic devices. Nearly all computers contain a quartz-crystal clock to regulate their operation. Moreover, not only do time signals beamed down from Global Positioning System satellites calibrate the functions of precision navigation equipment, they do so as well for mobile phones, instant stock-trading systems and nationwide power-distribution grids. So integral have these time-based technologies become to day-to-day existence that our dependency on them is recognised only when they fail to work.

AIR TRAFFIC CONTROL
IN THE USA
A An accident that occurred in the skies over the Grand Canyon in 1956 resulted in the establishment of the Federal Aviation Administration (FAA) to regulate and oversee the operation of aircraft in the skies over the United States, which were becoming quite congested. The resulting structure of air traffic control has greatly increased the safety of flight in the United States, and similar air traffic control procedures are also in place over much of the rest of the world.
B Rudimentary air traffic control (ATC) existed well before the Grand Canyon disaster. As early as the 1920s, the earliest air traffic controllers manually guided aircraft in the vicinity of the airports, using lights and flags, while beacons and flashing lights were placed along cross-country routes to establish the earliest airways. However, this purely visual system was useless in bad weather, and, by the 1930s, radio communication was coming into use for ATC. The first region to have something approximating today's ATC was New York City, with other major metropolitan areas following soon after.
C In the 1940s, ATC centres could and did take advantage of the newly developed radar and improved radio communication brought about by the Second World War, but the system remained rudimentary. It was only after the creation of the FAA that full-scale regulation of America's airspace took place, and this was fortuitous, for the advent of the jet engine suddenly resulted in a large number of very fast planes, reducing pilots' margin of error and practically demanding some set of rules to keep everyone well separated and operating safely in the air.
D Many people think that ATC consists of a row of controllers sitting in front of their radar screens at the nation's airports, telling arriving and departing traffic what to do. This is a very incomplete part of the picture. The FAA realised that the airspace over the United States would at any time have many different kinds of planes, flying for many different purposes, in a variety of weather conditions, and the same kind of structure was needed to accommodate all of them.
E To meet this challenge, the following elements were put into effect. First, ATC extends over virtually the entire United States. In general, from 365m above the ground and higher, the entire country is blanketed by controlled airspace. In certain areas, mainly near airports, controlled airspace extends down to 215m above the ground, and, in the immediate vicinity of an airport, all the way down to the surface. Controlled airspace is that airspace in which FAA regulations apply. Elsewhere, in uncontrolled airspace, pilots are bound by fewer regulations. In this way, the recreational pilot who simply wishes to go flying for a while without all the restrictions imposed by the FAA has only to stay in uncontrolled airspace, below 365m, while the pilot who does want the protection afforded by ATC can easily enter the controlled airspace.
F The FAA then recognised two types of operating environments. In good meteorological conditions, flying would be permitted under Visual Flight Rules (VFR), which suggests a strong reliance on visual cues to maintain an acceptable level of safety. Poor visibility necessitated a set of Instrumental Flight Rules (IFR), under which the pilot relied on altitude and navigational information provided by the plane's instrument panel to fly safely. On a clear day, a pilot in controlled airspace can choose a VFR or IFR flight plan, and the FAA regulations were devised in a way which accommodates both VFR and IFR operations in the same airspace. However, a pilot can only choose to fly IFR if they possess an instrument rating which is above and beyond the basic pilot's license that must also be held.
G Controlled airspace is divided into several different types, designated by letters of the alphabet. Uncontrolled airspace is designated Class F, while controlled airspace below 5,490m above sea level and not in the vicinity of an airport is Class E. All airspace above 5,490m is designated Class A. The reason for the division of Class E and Class A airspace stems from the type of planes operating in them. Generally, Class E airspace is where one finds general aviation aircraft (few of which can climb above 5,490m anyway), and commercial turboprop aircraft. Above 5,490m is the realm of the heavy jets, since jet engines operate more efficiently at higher altitudes. The difference between Class E and A airspace is that in Class A, all operations are IFR, and pilots must be instrument-rated, that is, skilled and licensed in aircraft instrumentation. This is because ATC control of the entire space is essential. Three other types of airspace, Classes D, C and B, govern the vicinity of airports. These correspond roughly to small municipal, medium-sized metropolitan and major metropolitan airports respectively, and encompass an increasingly rigorous set of regulations. For example, all a VFR pilot has to do to enter Class C airspace is establish two-way radio contact with ATC. No explicit permission from ATC to enter is needed, although the pilot must continue to obey all regulations governing VFR flight. To enter Class B airspace, such as on approach to a major metropolitan airport, an explicit ATC clearance is required. The private pilot who cruises without permission into this airspace risks losing their license.

26 A pilot entering Class C airspace is flying over an average-sized city.
READING PASSAGE 3
You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.
TELEPATHY
Can human beings communicate by thought alone? For more than a century the issue of telepathy has divided the scientific community, and even today it still sparks bitter controversy among top academics
Since the 1970s, parapsychologists at leading universities and research institutes around the world have risked the derision of sceptical colleagues by putting the various claims for telepathy to the test in dozens of rigorous scientific studies. The results and their implications are dividing even the researchers who uncovered them.
Some researchers say the results constitute compelling evidence that telepathy is genuine. Other parapsychologists believe the field is on the brink of collapse, having tried to produce definitive scientific proof and failed. Sceptics and advocates alike do concur on one issue, however: that the most impressive evidence so far has come from the so-called 'ganzfeld' experiments, a German term that means 'whole field'. Reports of telepathic experiences had by people during meditation led parapsychologists to suspect that telepathy might involve 'signals' passing between people that were so faint that they were usually swamped by normal brain activity. In this case, such signals might be more easily detected by those experiencing meditation — like tranquillity in a relaxing 'whole field' of light, sound and warmth.
The ganzfeld experiment tries to recreate these conditions with participants sitting in soft reclining chairs in a sealed room, listening to relaxing sounds while their eyes are covered with special filters letting in only soft pink light. In early ganzfeld experiments, the telepathy test involved identification of a picture chosen from a random selection of four taken from a large image bank. The idea was that a person acting as a 'sender' would attempt to beam the image over to the 'receiver' relaxing in the sealed room. Once the session was over, this person was asked to identify which of the four images had been used. Random guessing would give a hit-rate of 25 per cent; if telepathy is real, however, the hit-rate would be higher. In 1982, the results from the first ganzfeld studies were analysed by one of its pioneers, the American parapsychologist Charles Honorton. They pointed to typical hit-rates of better than 30 per cent — a small effect, but one which statistical tests suggested could not be put down to chance.
The implication was that the ganzfeld method had revealed real evidence for telepathy. But there was a crucial flaw in this argument — one routinely overlooked in more conventional areas of science. Just because chance had been ruled out as an explanation did not prove telepathy must exist; there were many other ways of getting positive results. These ranged from 'sensory leakage' — where clues about the pictures accidentally reach the receiver — to outright fraud. In response, the researchers issued a review of all the ganzfeld studies done up to 1985 to show that 80 per cent had found statistically significant evidence. However, they also agreed that there were still too many problems in the experiments which could lead to positive results, and they drew up a list demanding new standards for future research.
After this, many researchers switched to autoganzfeld tests — an automated variant of the technique which used computers to perform many of the key tasks such as the random selection of images. By minimising human involvement, the idea was to minimise the risk of flawed results. In 1987, results from hundreds of autoganzfeld tests were studied by Honorton in a 'meta-analysis', a statistical technique for finding the overall results from a set of studies. Though less compelling than before, the outcome was still impressive.
Yet some parapsychologists remain disturbed by the lack of consistency between individual ganzfeld studies. Defenders of telepathy point out that demanding impressive evidence from every study ignores one basic statistical fact: it takes large samples to detect small effects. If, as current results suggest, telepathy produces hit-rates only marginally above the 25 per cent expected by chance, it's unlikely to be detected by a typical ganzfeld study involving around 40 people: the group is just not big enough. Only when many studies are combined in a meta-analysis will the faint signal of telepathy really become apparent. And that is what researchers do seem to be finding.
What they are certainly not finding, however, is any change in attitude of mainstream scientists: most still totally reject the very idea of telepathy. The problem stems at least in part from the lack of any plausible mechanism for telepathy.
Various theories have been put forward, many focusing on esoteric ideas from theoretical physics. They include 'quantum entanglement', in which events affecting one group of atoms instantly affect another group, no matter how far apart they may be. While physicists have demonstrated entanglement with specially prepared atoms, no-one knows if it also exists between atoms making up human minds. Answering such questions would transform parapsychology. This has prompted some researchers to argue that the future lies not in collecting more evidence for telepathy, but in probing possible mechanisms. Some work has begun already, with researchers trying to identify people who are particularly successful in autoganzfeld trials. Early results show that creative and artistic people do much better than average: in one study at the University of Edinburgh, musicians achieved a hit-rate of 56 per cent. Perhaps more tests like these will eventually give the researchers the evidence they are seeking and strengthen the case for the existence of telepathy.

时间记录的历史
我们对时间的概念取决于我们测量时间的方式
有考古证据表明，至少5000年前，早在罗马帝国尚未出现之时，巴比伦人就开始测量时间，他们引进日历来统筹公共活动，计划货物装运，特别是管控作物种植和收割。日历的编排基于三个自然周期：以由地球绕地轴自转形成的连续的光明与黑喑为标记的太阳日;以由月球环绕地球公转形成的月相来衡量的太阴月;以及根据地球绕太阳公转形成的四季来定义的回归年。
在人造光发明以前，月亮对社会产生的影响尤为显著。尤其对于赤道附近的居民而言，月圆月缺比季节更替更加明显。因此，低纬度地区日历的形成更多受到月运周期的影响，而不是回归年。然而，在践行季节性农业的更偏北的气候带，回归年则更为重要。随着罗马帝国向北扩张，它的活动图表通常都是根据回归年而编排的。
早在罗马帝国建立几个世纪以前，埃及人就已制定了市政日历，规定一年有12个月，每月有30天，此外还有5天用来补充一个近似回归年。每10天以特定星群的出现为标志，这些星群被称作“德坎”(黄道十度分度)。天狼星刚好在日出之前升起，此时可以看见12个德坎横跨天空，而这一现象会在每年极其重要的尼罗河泛洪前后出现。埃及人赋予12个德坎的宇宙意义使他们形成一种新的系统，他们将每一个黑夜区间(之后又将每一个白昼区间)分成12等份。这些时段被称为日光时，因为它的持续时间随着季节更替引起的昼夜长度的变化而变化。夏季日光时长，冬季日光时短;只有在春分和秋分时白昼与黑夜的时长才是一致的。日光时最早被希腊人采用，然后由罗马人采用并传到欧洲，一直使用了2500多年。
为了在白天记录日光时，发明家们创造了日晷，用太阳阴影的长度和方向来指示时间。水钟与日晷作用相当，用于在夜晚测量日光时。最早的水钟之一是一个水盆，盆底附近有一个小孔，水通过小孔滴出来。随着水降至盆子内表面刻着的小时刻度线以下，水位降低的刻度就表示流逝的时间长度。尽管这些装置在地中海地区十分好用，但在多云并常有严寒天气的欧洲北部却不能一直使用。
机械钟的出现意味着尽管人们可以调试它以记录日光时，但机械钟本身更适合于记录长度相同的时间段。由此引发了一个问题，即计时该从何时开始。于是14世纪初，许多新型计时系统逐渐形成。人们计划将一天分为24个等份，而这些计划因为计时起点的术同而不向：意大利时间从日落开始算起，巴比伦时间从日出开始，天文学时间从中午开始，而德国一些大型公共时钟使用的“大钟”时间从午夜开始算起。最终，这些计时方法被“小钟”时间，即法国时间所取代，它将一天分成两个12小时时段，从午夜开始算起。
最早有记载的以重量驱动的机械钟1283年建于英国贝德福德郡。这种新型计时器所具有的革命意义既不在于依靠向下的重力提供起动力，也不在于依靠齿轮(至少有1300年的使用历史)传递动力，而在于它使用了一个叫做擒纵机构棘轮装置的部件。15世纪初人们又创造出了螺旋弹簧，也被称为均力圆锥轮。尽管主发条承受着不断变化的张力，但该装置仍能为钟表齿轮提供恒力。到了16世纪，人们发明了摆钟。但由于钟摆摆动弧度很大，因此并不十分有效。
为了解决这个问题，原有擒纵机构棘轮装置的改进装置1670年在英格兰发明出来。该装置被称为锚型擒纵机构，以杠杆为基础，形状像一艘船的锚。钟摆的动作对该设备产生振动，以使它抓紧而后释放擒纵机构棘轮装置的每一个齿，从而使得齿轮精确地旋转。与早期摆钟中所使用的原始装置不同，锚型擒纵机构使钟摆的摆动弧度变得很小。此外，这一发明使得摆钟可以使用长摆，一秒钟摆动一下，从而引发了新型落地柜式造型的开发，也就是落地摆钟。
如今，高度精确的计时工具为大多数电子设备设置时间。几乎所有的计算机都带有石英钟以控制其运行。此外，从全球定位系统卫星发射的时间信号不仅校准精密导航设备的功能，还被用于移动电话、即时股票交易系统和全国电力分配网。这些以时间为基础的技术已完全成为日常生活的一部分，只有当它们无法正常工作时，我们才会意识到人类多么依赖这些技术。
TEST 1 PASSAGE 2 参考译文：
美国航空交通管制
A. 1956年美国大峡谷上空发生的一起事故促成了联邦航空局(FAA)的成立。该局负责管理和监督美国越来越拥挤的天空。由此形成的空中交通管制结构大大增加了飞机在美国的飞行安全，世界其他很多地方也采取了类似的空中交通管制程序。
B.早在大峡谷灾难发生之前就存在雏形的航空交通管制(ATC)。早在20世纪20年代初，最早的空中交通管制员在机场附近用灯和标志旗手动引导飞机。当时，灯标和闪光灯沿着越野路线放置以建立最早的航线。然而，这种纯粹的视觉系统在恶劣天气情况下是无用的。到20世纪30年代，航空交通管制开始使用无线电通讯。首个采用类似于今天的航空交通管制的地方是纽约市，其他主要的大都市紧随其后。
C.20世纪40年代，航空交通管制中心利用了第二次世界大战催生出的新研制的雷达和改进后的无线电通讯技术，但管制系统仍然很不成熟。直到联邦航空局分创建以后，美国才开始进行全面的领空管制。而这一事件却是偶然的，因为喷气式发动机的产生突然导致大批快速飞机的出现。这些飞机减少了飞行员的误差幅度，并且需要实际的整套规则以使飞机之间保持良好的分离状态，在空中安全行驶。
D.很多人认为，航空交通管制就是一排管理人员坐在国家机场的雷达屏幕前指挥着抵港及离港的交通。这只是整个场景中的一部分。美国联邦航空局认识到每时每刻都会有许多不同种类的飞机，为了这样那样的目的，在各种各样的天气情况下飞行在美国的空中。因此，急需一个能够容纳所有情况的同一体系。
E.为了迎接这一挑战，美国联邦航天局实施了以下重要措施。首先，让航空交通管制几乎遍及整个美国。一般来说，离地面365米以及更高的地方，整个国家都被管制空域覆盖。在某些地区，主要是靠近机场的地带，管制空域扩大到自地面215米以上的范围，而在紧邻机场的区域，管制空域包括地面以上所有区域。管制空域是美国联邦航空局规定适用的空域。在其他非受控空域，飞行员受到的限制较少。如此一来，那些出于娱乐目的只想短时间飞行而不受美国联邦航空局规定限制的飞行员就只能停留在365米以下的非受控领空，而希望得到航空局保护的飞行员可以很容易地进人管制空域。
F.然后，美国联邦航空局确认了两种类型的飞行环境。在气象条件良好的情况下，飞行员可按照目视飞行规则(VPR)飞行。该规则主要依靠视觉线索来维持可接受的安全水平。低能见度使建立一套仪表飞行规则(IFR)成为必需。根据该规则，飞行员依靠飞机仪表盘提供的飞行高度和导航信息确保飞行安全。天气晴朗时，管制空域内的飞行员可以选择在目视飞行规则或仪表飞行规则下飞行，而美国联邦航空局 的规定在同一空域同时适用于两套规则的实施。但如果飞行员的仪表等级超出或低于了其必须持有的基本飞行员执照规定的等级，飞行员只能选择遵循仪表飞行规则。
G.管制空域分为几个不同的类型，以英文字母命名。非受控空域被定为F级，而海拔5490米以下非紧邻机 场的受控空域被定为E级。5490米以上的所有空域被定为A级。E级和A级是根据其间飞行的不同飞机类型而划分的。一般来说，通用航空飞机(这类飞机的飞行高度大多不超过5490米)和商业涡轮螺旋桨飞机在E级空域飞行。5490米以上是大型喷气机的领空，因为喷气式发动机的效率随着高度的增加而增高。E级和A级之间的区别在于A级空域中所有的操作都遵循仪表飞行规则，飞行员必须具有仪表级别，换言之，必须熟练掌握飞机仪表的使用并获得许可。因为航空交通管制对整个空域的控制是至关重要的。其他三个等级：D级、C级和B级用于管理机场附近的区域。这三个级别大致分别适用于小型城市、中等城市和大型城市的机场，包含了一套越来越严格的规章制度。例如，目视飞行规则飞行员如要进入C级空域，必须与航空交通管制建立双向无线电联系。航空交通管制无需提供明确的进人许可，但飞行员必须始终遵守在目视飞行规则下飞行的所有规定。如要进人B级空域，比如飞临主要城市机场，则必须有明确的航空交通管制许可。未经许可进入领空的私人飞行员可能会被吊销飞行执照。
TEST 1 PASSAGE 3 参考译文：
心灵感应
人类可以仅凭思想沟通吗?一个多世纪以来，心灵感应问题一直使科学界意见不一，直至今天依然在学界精英中引发着激烈的争论。
上世纪70年代以来，世界各地顶尖高校和科研院所的超心理学家冒着遭受那些持怀疑态度的同事们嘲笑的危险，将关于心灵感应的各种断言假说放人几十个严谨的科学研究中进行试验。试验的结果及其启 示甚至将发现该结果的研究者们也分成了几派。
一些研究者认为试验结果构成令人信服的证据，表明心灵感应是真实存在的。其他超心理学家则认为该学科曾试图提出明确的科学论证，但却失败了，因此正处于瓦解的边缘。不过，怀疑者和倡导者却在一 个问题上达成共识：即迄今为止令人印象最为深刻的证据出自所谓的“ganzfeld”(超感官知觉全域测试)实验中，这一德文术语的意思是“整个领域”。人类在冥想状态下的心灵感应体验报告使超心理学家怀疑心灵感应可能包含人与人之间传递的“信号”。这种信号十分微弱，以至于往往被正常的大脑活动所淹没。如此说来，这种信号可能更容易被那些沉浸于冥想般宁静中的人检测到。他们所处的“整个领域”有着令人放松的灯光，怡人的声音和温暖的环境。
超感官知觉全域测试试图重新营造这些条件，让参与者坐在一个封闭房间里的柔软躺椅上，听着令人放松的声音，用特殊滤光器将参与者的眼睛蒙住，使他们只能看见柔和的粉红色光线。在早期的超感官知觉全域测试实验中，心灵感应测试包括识别从大型图片库中随机选择的四张图片中的其中一张。试验的想 法是有一个人作为“发送者”，尝试把图像发送给在封闭房间中休息的“接收者”。传递过程结束时，接收者 需要回答四张图片中的哪一张是刚刚使用过的。随机猜测的命中率是25%,但如果心灵感应是真实存在的，命中率应该更高。1982年，此项研究的先驱者之一，美国超心理学家Charles Honorton对第一批超感官知觉全域测试研究结果进行了分析。研究结果显示了高于30%的典型命中率。虽然效果不甚明显，但统计测试显示不能将它归因于偶然。
其言下之意是超感官知觉全域测试方法揭示了心灵感应的真实证据。但这种说法有一个关键的漏洞—— 一个在较传统的科学领域经常被忽视的问题。仅仅由于这种解释排除了偶然因素并不能证明心灵感应一定存在;通过很多其他的方法也能获得积极结果。这些可能性既包括“感官泄漏”，即与图片有关的线索意外地传给了接收者，也包括彻底的欺诈。作为回应，研究者们发表了一份综述，总结了 1985年以前进行的所有超感官知觉全域测试研究，以表明80%的研究都发现了有统计意义的证据。但他们也同意目前实验中尚有太多的问题可能导致积极的结果，他们还草拟了一份清单，要求为今后的研究设立新的标准。
此后，许多研究人员转向了自动超感官知觉全域测试，这是一种技术的自动化变体，也就是使用电脑完成许多关键任务，如随机选择图像。通过最大限度地减少人为参与，这一想法是要将有缺陷的结果最小化。1987年，Honorton使用“荟萃分析”，即从一系列研究中寻找整体结果的统计技术，对上百次的自动超感官知觉全域测试结果进行了研究。结果虽然没有以往引人注目，却仍然令人印象深刻。
然而，一些超心理学家仍然为单个超感官知觉全域测试研究之间缺乏一致性感到烦恼。心灵感应捍卫者指出，要求每一项研究都提供令人印象深刻的证据忽略了一个基本的统计事实：检测这些微小影响需要大量的样本支持。如果像目前研究结果表明的那样，心灵感应的命中率仅仅略高于概率预测的25%，涉及40人左右的典型超感官知觉全域测试也不太可能检测得到：试验群体根本不够大。只有当大量研究结合在一个荟萃分析之中，心灵感应的微弱信号才会真正明显起来。而这似乎正是研究者们所发现的。
然而，他们肯定当然不会发现主流科学家们的态度有任何变化：大部分人仍然完全排斥心灵感应的观点。至少一部分问题在于心灵感应缺乏合理的机制。
各种理论都被提了出来，很多以理论物理学的深奥思想为重点。其中包括“量子纠缠”：无论两组原子间距离多么遥远，影响一组原子的事件都会立即影响另一组原子。虽然物理学家们用专门准备的原子演示了“纠缠”，但这一现象是否同样存在于构成人类头脑的原子中却无人知晓。对于这些问题的回答将改变超心理学。这使得一些研究人员认为该学科的未来不在于收集更多心灵感应的证据，而在与探索其可能的机制。一些工作已经开始进行，研究人员试图识别在自动超感官知觉全域测试中特别成功的被试者。早期的结果表明有创造力和艺术性的人们的表现要远远高于平均水平：在爱丁堡大学的一次研究中，音乐家的测试命中率高达56%。或许更多诸如此类的测试最终将为研究人员提供他们正在寻求的证据，巩固加强心灵感应存在的依据。

答案： v
关键词： oversimplified
定位原文： D段第1、2句“Many people think that...This is a very incomplete part of the picture.”
解题思路: D段首句阐述了一个大众观点(many people think...)，接着第二句指出这个观点过于片面。题干中的 oversimplified相当于原句中的 incomplete。
Question 17
答案： iv
关键词： altitude zones
定位原文： E段第2句“First, ATC extends over virtually …”
解题思路： E段第二句中提出让航空交通管制几乎遍及整个美国，接着分别讲述了不同高度的空域管制情况(from 365m above the ground and higher, 215m above the ground, below 365m...)因此答案为iv。
Question 18
答案: viii
关键词： weather conditions
定位原文： F段第1句“The FAA then recognized…”
解题思路: F段首句提出FAA确认了两种飞行环境。接着对这两种环境进行了解释说明，即在气象条件良好的情况下，飞行员可按照目视飞行规则(VFR)飞行;在低能见度的情况下，飞行员则须按照仪表飞行规则(IFR)飞行。因此答案是viii。
Question 19
答案: vii
关键词： airspace categories
定位原文： G段第1句“Controlled airspace is divided into…”
解题思路： G段首句点出此段主要阐述管制空域的分类(controlled airspace…different types)。因此答案为vii。文章中的 types 与选项 vii 中的 categories 对应。
Question 20
答案： FALSE
关键词： FAA, created as result of
定位原文： A段第1句“An accident that occurred in the skies…”
解题思路： 文章中第 1 句明确说 FAA 成立的原因是空难, 题目中却说是由于喷气式引擎出现, 题目表述与文章矛盾。
Question 21
答案： FALSE
关键词： Air Traffic Control, the Grand Canyon crash
定位原文： B段第1句“Rudimentary air traffic control (ATC) existed…”
解题思路： 文章中明确说是ATC existed well before the Grand Canyon disaster, 与题目中 started after 直接相反。

答案: TRUE
关键词: Class F, 365m
定位原文: G段第2句“Uncontrolled airspace …” E段第3、4句和最后1句
解题思路：通过定位词Class F可快速定位至G段处，但是只能确定Class F为uncontrolled airspace,通过该短语及365m可继续定位于E段。E段定位句说明从365米往上的区间为controlled airspace，且在大部分near airports的区域，215米以上的区间都是controlled airspace，因此可以逆推出uncontrolled airspace的情况。故此题答案为TRUE。
Question 25
答案： FALSE
关键词： Class E airspace, IFR
定位原文：G段第7句“The difference between Class E and…”
解题思路：此题通过定位词能够迅速定位。定位句的含义为“E级和A级之间的区别在于A级领空中所有的操作都遵循仪表飞行规则”。显然题干信息与定位句内容矛盾。此题还可以按照绝对化词汇all和must来快速判定答案。故此题答案为FALSE。

定位原文：第8段第4、5句“Answering such questions would…”
解题思路：第四句中的transform对应题干中的alter，第五句中才提及研究者们的attitude,即该研究的未来在于探究可能的机制(mechanisms)。故正确答案为A。
Question 30：
答案： F
关键词： autoganzfeld trials, success
定位原文：第8段倒数第2、3句“Some work has begun already …”
解题思路：此题通过定位词可以迅速定位到第八段倒数第三句，倒数第二句指出有创造力和艺术性的人们表现得更好。因此可知样本的选择对命中率会有很大影响。故正确答案为F。
Question 31：
答案： sender
关键词： Ganzfeld studies, 1982, person, acting as, four
定位原文：第3段第3句“The idea was that a person…”
解题思路：由空格前冠词和空格后的定语从句引导词 who 可知本题需填入一个指代人的单数可数名词。通过题目中数字 1982 迅速定位至文章第三段。再通过数字 four 定位至该段第 5 行。本题答案为 sender。
Question 32：
答案： picture/image
关键词： one, random selection, four
定位原文： 第3段第2句“In early ganzfeld experiments…”
解题思路： 此题轻微乱序，但定位词很明显且定位句是上一题定位句的前一句。空格所填词应为从random selections of four中picked out的宾语。所以此题填picture/image。题干中的picked out与原文中的chosen from属于同义转述。
Question 33：
答案： receiver
关键词： ichthyosaurs, can be determined by, appearance
定位原文：第3段第4句“Once the session was over, this …”
解题思路：此题定位较易。空格所填词应为 identify这一动作的发出者，定位句中与之相对应的是指代词this person,于是倒着往回看上一句，即第31题对应句，可以找出this person的具体指代对象。所以此题填receiver。
Question 34：
答案： sensory leakage
关键词： flaw, positive results
定位原文：第4段第4句“...there were many other ways of getting positive results. These ranged from ‘sensory leakage…”
解题思路：此题根据定位词及顺序原则可定位至第四段第四行最后，其中many other ways对应题干中的factors，具体内容在接下来的一句中。所以此题填sensory leakage。
Question 35：
答案： outright fraud
关键词： or
定位原文：第4段第4句““...there were many other ways of getting positive results. These ranged from ‘sensory leakage…”

解题思路： 空格所填词应为被用来完成key tasks的对象，文中的perform对应题干中的were used for。所以此题填computers。
Question 37：
答案： human involvement
关键词： limit
定位原文：第5段第2句“By minimising human involvement...”
解题思路：此题按照顺序原则定位，原文中的 minimising对应题干中的limit,空格所填词应为被限制的对象。所以此题填human involvement。
Question 38：
答案： meta-analysis
关键词： results, subjected to a
定位原文： 第5段倒数第2句“In 1987, results from hundreds…”
解题思路： 空格所填词应为 subject to的对象。所以此题填meta?-analysis。
Question 39：
答案： lack of consistency
关键词： flaw, different test results
定位原文： 第6段第1句“Yet some parapsychologists…”
解题思路： 此题定位较难，文中的individual ganzfeld studies与题干中的different test对应。空格所填词应为不同实验结果之间的关系。所以此题填lack of consistency。
Question 40：
答案： big/large enough
关键词： fact, sample group, not
定位原文：第6段倒数第3句“...the group is just not big enough.”
