老託福閱讀試題及答案：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.

託福閱讀出題點列舉
託福閱讀出題點一、列舉和並列句
列舉指的是： First,... Second,... Third,.。。等逐條列出。並列句是指：A ，B and C，即逐項列出。它們共同的特徵是列出二點或三點以上的條目。該類型語言點常考的題型是“細節性問題”，主要有兩種：
1. Which 題型
該題型只要求從並列的三頂中選一項作爲答案，其它條目與題目無關。在這種情況下，往往題目的答案出自最後一個選項。
2 . EXCEPT 題型
該題型俗稱“三缺一”題型，即題目 4 個選項中有三個符合文章內容，剩下一個不符合，題目便是要求選出這個不符合文章內容的選項。例如： All of the following are mentioned as types of evidence concerning handedness EXCEPT ??? 這種題型只適合於考並列、列舉句，這是因爲它要求其三個選項一定是文章中出現的，也就是並列或列舉之處。利用這一特點。我們在讀文章的時候就可多留意，如看到並列、列舉句，可預想其有可能被考到;如發現題目中有“三缺一”題型，則應到並列、列舉處找答案。
託福閱讀出題點二、否定及轉折句
託福聽力段落題型及解題要點
如何用逆向搜索法得高分
如何提高託福聽力水平
否定句是指帶有 NO 或 NOT ， NEVER 等否定詞的句子，而轉折句則指帶有 HOWEVER ， BUT 或RATHER 等關聯詞引導的句子，它們可以用下面的句型說明： A is not B ， as C ， but is D 。對於以上的句型常出“推斷性問題”。
託福閱讀出題點三、舉例句
句中由 as 或 such as ， for example 等引導的短語或句子爲舉例句，常考“推斷性問題”和“細節性問題”。上面句型中的 as C 爲插入的舉例句。
託福閱讀出題點四、數字與年代
文中的數字、年代、日期等常常是出題者注意的考題點，如 1996 年 10 月第 48 題。
託福閱讀出題點五、最高級及絕對性詞彙
文章中若出現 must ， all ， only ， anyone ， always ， never 等絕對性詞彙或 first ， most beautiful 等最高級詞彙，往往是考題要點，一般出“細節性題目”。這是因爲它們都有一個共同的特點，那就是 概念絕對 ， 答案唯一 ，無論是出題還是做題，不會產出歧義和疑問，因此很容易出題，答案絕對正確。相反地，如果文章中出現相對性的詞彙、例如 Some of the people chose red hats,some chose green hats,and others blue ones. 其中 some 爲相對性詞彙，如果我們出這樣一道題： What color hats did some people choose? 那麼就沒有唯一正確的答案，因爲有可能爲 red,green 或 blue ，給評卷帶來困難。
託福閱讀出題點六、比較級及比喻
如果文中含有 more than 或 as ??? as ，like ( a fly )等句型，則爲比較級或比喻句結構，往往也是考題點，一般出“推斷性題目”。
託福閱讀出題點七、同位語及插入語
文章中帶有由 that is ，i.e. ，or 等詞彙引導的名詞詞組，放在一個名詞後面，爲同位語;插入語是指副詞、不定式、分詞、從句等結構故在句首，句中或句尾，不做句子成分，但修飾整個句子、表達作者感情的語法結構。 這些用逗號隔開的持殊結構往往也是考查的重點，一般會出“細節性題目”。
託福閱讀出題點八、因果句
句中若有如下結構或詞彙的稱爲因果句：
(1) 因果連詞：because，since，for，as，therefore，so，consequently 等
(2)表示因果的動詞：cause ，result in ，originate from 等;
(3) 表示因果的名詞： base, basis, result,consequence 等，這些因果句都是指明某兩個事件之間因果關係的，尤爲出題者所青陳。因爲通過出題可以考查文中兩個事件內在的因果關係。此種句型一般出“推斷性問題”。
託福閱讀出題點九、段落句
文章各段第一句( 段首句 )和末段員後一句( 文尾句 )都是十分重要的地方，往往是文章作者表達中思想，進行總結綜述的地方，因此常出(1)主題性問題，(2)細節性問題(3)結構性問題。
託福閱讀出題點十、特殊標點
有一些特殊標點的含義也屬於考查範圍，它們是：
(1) 破折號，表示解釋。考細節性問題;
(2) 括號，表示解釋。考細節性問題;
(3) 冒號，一股同上，有時冒號也表示列舉，則考“ EXCEPT ”題目;
(4) 引號。表示引用，考細節性問題：
(5) 驚歎號，表示作者感情，考態度性問題。
綜上所述，我們可以利用上面所介紹的考題點，作爲“路標”，迅速地指引我們找到正確答案;問時作爲出題規律，檢驗自己所選答案的正確性。
