怎么样加强雅思阅读,要避开几大误区
以为自己在雅思阅读上下了足够的苦工,但实际上你可能只是在不断地重复错误。为了避免大家在雅思阅读备考上跳坑,下面就为大家总结雅思阅读备考的常见错误,一起来看吧。
怎么样加强雅思阅读,要避开几大误区
雅思阅读备考错误之死记词汇
很多同学都明白雅思考试最重要的基石是词汇,所以一开始就抱着一本很厚的词汇书从A到Z狠下决心死死记忆。可是好景不长,很难有同学将这么一个艰巨的工程进行到底的。
事实上,阅读考到6分真的需要很大的词汇量吗?其实如果能熟练掌握4000个词,阅读6分以上是完全可以实现的。
我们要做的,只有两件事情: 1.明白哪些单词是要重点掌握的;2.把这些单词记得滚瓜烂熟。
雅思阅读备考错误之题海战术
很多学生都认为阅读就是要多做题,做得越多,分数越高。这种思想并非绝对错误,但是有很多值得商榷的地方。
首先,烤鸭们要保证练习所选题目的考试策略和出题思路,应当和雅思阅读考试保持高度一致;其次,做完题目之后不应该只是对对答案就草草了事,而应该去精读分析相关的出题句子,记忆词汇,整理长难句。
建议烤鸭们以剑桥真题为主,不仅要满足把题做对,更要花功夫理解跟解题相关的句子。
雅思阅读备考错误之不会取舍
举个例子,如果是想考到阅读6分的烤鸭,大家一定要理清现实,认清形势!阅读考6分只需要你做对24个题目。换句话说,你可以错掉16个题目,分到3篇文章,每篇你只需要做对8个。这样的数据结果显示就一目了然,也就不要给自己太大压力。想要做全对,很可能结果一塌糊涂。
关键时候,该猜的就猜,该蒙的就蒙,该跳过就跳过。所以建议大家在考试的时候一定要学会舍弃,有些多选题太费时间,干脆就不要做了,看看题干,踢掉绝对意义的选项,快速解决。
断题定位不到,也就别费时间了,意义绝对的选FALSE或者No,意义相对的选TRUE或者YES,剩下的全部选择一个选项。
雅思阅读模拟真题原文:Sun's fickle heart may leave us cold
Sun's fickle heart may leave us cold
1 There's a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 years - exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star's core.
2 Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled the effect of temperature fluctuations in the sun's interior. According to the standard view, the temperature of the sun's core is held constant by the opposing pressures of gravity and nuclear fusion. However, Ehrlich believed that slight variations should be possible.
3 He took as his starting point the work of Attila Grandpierre of the Konkoly Observatory of the Hungarian Academy of Sciences. In 2005, Grandpierre and a collaborator, Gábor ágoston, calculated that magnetic fields in the sun's core could produce small instabilities in the solar plasma. These instabilities would induce localised oscillations in temperature.
4 Ehrlich's model shows that whilst most of these oscillations cancel each other out, some reinforce one another and become long-lived temperature variations. The favoured frequencies allow the sun's core temperature to oscillate around its average temperature of 13.6 million kelvin in cycles lasting either 100,000 or 41,000 years. Ehrlich says that random interactions within the sun's magnetic field could flip the fluctuations from one cycle length to the other.
5 These two timescales are instantly recognisable to anyone familiar with Earth's ice ages: for the past million years, ice ages have occurred roughly every 100,000 years. Before that, they occurred roughly every 41,000 years.
6 Most scientists believe that the ice ages are the result of subtle changes in Earth's orbit, known as the Milankovitch cycles. One such cycle describes the way Earth's orbit gradually changes shape from a circle to a slight ellipse and back again roughly every 100,000 years. The theory says this alters the amount of solar radiation that Earth receives, triggering the ice ages. However, a persistent problem with this theory has been its inability to explain why the ice ages changed frequency a million years ago.
7 "In Milankovitch, there is certainly no good idea why the frequency should change from one to another," says Neil Edwards, a climatologist at the Open University in Milton Keynes, UK. Nor is the transition problem the only one the Milankovitch theory faces. Ehrlich and other critics claim that the temperature variations caused by Milankovitch cycles are simply not big enough to drive ice ages.
8 However, Edwards believes the small changes in solar heating produced by Milankovitch cycles are then amplified by feedback mechanisms on Earth. For example, if sea ice begins to form because of a slight cooling, carbon dioxide that would otherwise have found its way into the atmosphere as part of the carbon cycle is locked into the ice. That weakens the greenhouse effect and Earth grows even colder.
9 According to Edwards, there is no lack of such mechanisms. "If you add their effects together, there is more than enough feedback to make Milankovitch work," he says. "The problem now is identifying which mechanisms are at work." This is why scientists like Edwards are not yet ready to give up on the current theory. "Milankovitch cycles give us ice ages roughly when we observe them to happen. We can calculate where we are in the cycle and compare it with observation," he says. "I can't see any way of testing [Ehrlich's] idea to see where we are in the temperature oscillation."
10 Ehrlich concedes this. "If there is a way to test this theory on the sun, I can't think of one that is practical," he says. That's because variation over 41,000 to 100,000 years is too gradual to be observed. However, there may be a way to test it in other stars: red dwarfs. Their cores are much smaller than that of the sun, and so Ehrlich believes that the oscillation periods could be short enough to be observed. He has yet to calculate the precise period or the extent of variation in brightness to be expected.
11 Nigel Weiss, a solar physicist at the University of Cambridge, is far from convinced. He describes Ehrlich's claims as "utterly implausible". Ehrlich counters that Weiss's opinion is based on the standard solar model, which fails to take into account the magnetic instabilities that cause the temperature fluctuations.
