Question

17．It is well-known that twins are closer to each other than most brothers and sisters----after all，they probably spend more time with each other．Parents of twins often notice that they develop special ways of communicating：they invent their own words and one can often finish the other's sentence．In exceptional circumstances，this closeness becomes more extreme：they invent a whole language of their own，as in the case of Grace and Virginia Kennedy from Georgia in the USA，who communicated so successfully in their own special language that they did not speak any English at all until after they started school．
However，these special relationships are the result of lives spent almost entirely in each other's company．What happens when twins do not grow up together，when they are separated at birth for some reason？Are they just like any other strangers，or are there still special similarities between them？Professor Tom Bouchard，of the University of Minnesota，set out to find the answer to this question．He traced sixteen pairs of twins，who were adopted by different families when they were babies，and often brought up in very different circumstances．Each twin was then interviewed about every small detail of their life．
The results of this research make a surprising reading．Many of the twins were found to have the same hobbies，many have suffered the same illnesses，and some have even had the same type of accident at the same point in their lives．One pair of middle-aged women arrived for their first meeting in similar dresses，another pair were wearing similar jewellery．The most incredible similarities are to be found in the case of Jim Springer and Jim Lewis from Ohio in the USA．The story of the'Jim Twins'made headline news across USA．Born to an immigrant woman in 1939，and adopted by different families at birth，both babies were named Jim by their new parents．
But what can be the explanation for these remarkable similarities？Is it all pure coincidence，or is the explanation in some way genetic？Research into the lives of twins is forcing some experts to admit that our personalities may be at least partly due to'nature'．On the other hand，analysts are also anxious to emphasise that incredible coincidences do happen all the time，not just in the lives of twins．
73．The case of Grace and Virginia Kennedy （Para.1）is to show thatA．
A．twins communicate with each other in an unusual way
B．twins are more likely to suffer from speaking problems
C．most twins have exceptional abilities to invent a new language
D．twins won't have an effective communication until they go to school

A．what will happen if twins spend lives entirely in the same company
B．why the 16 pairs of twins have been adopted by different families
C．whether separated growing up has effect on twins'special similarities
D．when the special similarities come into being during their growing up
75．What does the word"reading"in Paragraph 3 most probably mean？B
A．Book．B．Interpretation．C．Literature．D．Measurement．
76．According to Tom Bouchard's research，the special similarities between twinsD
A．depend on what the twins enjoy and suffer from
B．can not be proved or accepted by all the experts
C．result from the twins'growing up and development
D．are not closely linked with where the twins are raised
77．What can be learned from the last paragraph？C
A．Incredible coincidences happen to twins all the time．
B．Nature is the only way to explain the similarities between twins．
C．The differences between twins are to some extent the results of genes．
D．Similarities shows the close relationship between two strange persons．

Answer 1

分析 本文论述了双胞胎之间会有如此多的相似之处是由共同的生活环境决定的还是由基因决定，根据Tom Bouchard教授的研究结果，可知双胞胎的相似之处很大程度上是天生的，即由基因决定的．

解答 ACBDC
73．答案 A 推理判断题 根据第一段Parents of twins often notice that they develop special ways of communicating：they invent their own words and one can often finish the other's sentence．可知，作者用Grace and Virginia Kennedy两个人的例子来证明"双胞胎可以以一种非同寻常的方式来交流"，故答案为A
74．答案 C 细节理解题 根据What happens when twins do not grow up together，when they are separated at birth for some reason？Are they just like any other strangers，or are there still special similarities between them？Professor Tom Bouchard，of the University of Minnesota，set out to find the answer to this question．可知，Professor Tom Bouchard研究的目的是看看分别长大的双胞胎还会有如此多的相似性，故答案为C
75．答案B 词义猜测题 根据下文Many of the twins were found to have the same hobbies，many have suffered the same illnesses，and some have even had the same type of accident at the same point in their lives．可知，研究结果是令人吃惊的，reading此处的意思为"解读，阐释"，故答案为B
76．答案 D 推理判断题 根据Research into the lives of twins is forcing some experts to admit that our personalities may be at least partly due to'nature'．可知，双胞胎即使分别被抚养长大仍然有如此多的相似之处，说明这不是由环境影响，而很可能是由基因决定的，故答案为D
77．答案 C 主旨归纳题 根据Research into the lives of twins is forcing some experts to admit that our personalities may be at least partly due to'nature'．可知双胞胎的相似之处很大程度上是天生的，即由基因决定的，故答案为C

点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．
