老托福阅读试题及答案：PASSAGE 30
Butterflies are among the most extensively studied insects — it is estimated that 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.
Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions. For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed.
A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates. In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.
In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

托福阅读出题点列举
托福阅读出题点一、列举和并列句
列举指的是： First,... Second,... Third,.。。等逐条列出。并列句是指：A ，B and C，即逐项列出。它们共同的特征是列出二点或三点以上的条目。该类型语言点常考的题型是“细节性问题”，主要有两种：
1. Which 题型
该题型只要求从并列的三顶中选一项作为答案，其它条目与题目无关。在这种情况下，往往题目的答案出自最后一个选项。
2 . EXCEPT 题型
该题型俗称“三缺一”题型，即题目 4 个选项中有三个符合文章内容，剩下一个不符合，题目便是要求选出这个不符合文章内容的选项。例如： All of the following are mentioned as types of evidence concerning handedness EXCEPT ??? 这种题型只适合于考并列、列举句，这是因为它要求其三个选项一定是文章中出现的，也就是并列或列举之处。利用这一特点。我们在读文章的时候就可多留意，如看到并列、列举句，可预想其有可能被考到;如发现题目中有“三缺一”题型，则应到并列、列举处找答案。
托福阅读出题点二、否定及转折句
托福听力段落题型及解题要点
如何用逆向搜索法得高分
如何提高托福听力水平
否定句是指带有 NO 或 NOT ， NEVER 等否定词的句子，而转折句则指带有 HOWEVER ， BUT 或RATHER 等关联词引导的句子，它们可以用下面的句型说明： A is not B ， as C ， but is D 。对于以上的句型常出“推断性问题”。
托福阅读出题点三、举例句
句中由 as 或 such as ， for example 等引导的短语或句子为举例句，常考“推断性问题”和“细节性问题”。上面句型中的 as C 为插入的举例句。
托福阅读出题点四、数字与年代
文中的数字、年代、日期等常常是出题者注意的考题点，如 1996 年 10 月第 48 题。
托福阅读出题点五、最高级及绝对性词汇
文章中若出现 must ， all ， only ， anyone ， always ， never 等绝对性词汇或 first ， most beautiful 等最高级词汇，往往是考题要点，一般出“细节性题目”。这是因为它们都有一个共同的特点，那就是 概念绝对 ， 答案唯一 ，无论是出题还是做题，不会产出歧义和疑问，因此很容易出题，答案绝对正确。相反地，如果文章中出现相对性的词汇、例如 Some of the people chose red hats,some chose green hats,and others blue ones. 其中 some 为相对性词汇，如果我们出这样一道题： What color hats did some people choose? 那么就没有唯一正确的答案，因为有可能为 red,green 或 blue ，给评卷带来困难。
托福阅读出题点六、比较级及比喻
如果文中含有 more than 或 as ??? as ，like ( a fly )等句型，则为比较级或比喻句结构，往往也是考题点，一般出“推断性题目”。
托福阅读出题点七、同位语及插入语
文章中带有由 that is ，i.e. ，or 等词汇引导的名词词组，放在一个名词后面，为同位语;插入语是指副词、不定式、分词、从句等结构故在句首，句中或句尾，不做句子成分，但修饰整个句子、表达作者感情的语法结构。 这些用逗号隔开的持殊结构往往也是考查的重点，一般会出“细节性题目”。
托福阅读出题点八、因果句
句中若有如下结构或词汇的称为因果句：
(1) 因果连词：because，since，for，as，therefore，so，consequently 等
(2)表示因果的动词：cause ，result in ，originate from 等;
(3) 表示因果的名词： base, basis, result,consequence 等，这些因果句都是指明某两个事件之间因果关系的，尤为出题者所青陈。因为通过出题可以考查文中两个事件内在的因果关系。此种句型一般出“推断性问题”。
托福阅读出题点九、段落句
文章各段第一句( 段首句 )和末段员后一句( 文尾句 )都是十分重要的地方，往往是文章作者表达中思想，进行总结综述的地方，因此常出(1)主题性问题，(2)细节性问题(3)结构性问题。
托福阅读出题点十、特殊标点
有一些特殊标点的含义也属于考查范围，它们是：
(1) 破折号，表示解释。考细节性问题;
(2) 括号，表示解释。考细节性问题;
(3) 冒号，一股同上，有时冒号也表示列举，则考“ EXCEPT ”题目;
(4) 引号。表示引用，考细节性问题：
(5) 惊叹号，表示作者感情，考态度性问题。
综上所述，我们可以利用上面所介绍的考题点，作为“路标”，迅速地指引我们找到正确答案;问时作为出题规律，检验自己所选答案的正确性。
