　　试题答案及解析：

　　1. AFor these children to develop to their full adult potential在句中做目的状语，these children 是to develop 的逻辑主语，这种主谓关系在目的状语中一般是不能用分词表示的。B中不定式被动式与句意相悖;for不是连词，故不能选D，否则语句不通。

　　2. Cas well as 在语法功能上相当于介词，所以在句中要接动名词leading to。

　　3. C句子的主语为solar power or fission power，谓语是may give, collected by satellite circling the earth是后置定语修饰solar power，其中circling the earth 又是现在分词短语修饰satellite，“环绕地球的卫星”，相当于the satellite which circles the earth。其他选择项均不符合句子语法结构要求。

　　4. C句中已给出频次状语several times，说明要用完成时态，同时句子的时态定位是现在时they are wakened，显然不能用过去完成时，所以选C。

　　5. C这是一个so…that结构表示结果状语的句型， A、D 可以排除。在that从句中又有条件从句，而且应该是虚拟语气结构，B中没有表示条件的连词，是错误的。C虽然也没有连词if，但采用了倒装结构，可以将if省略，又是had done，表示与过去事实相反的假设，时态、结构完全正确，因此是惟一正确的选择。

　　A. are

　　B. is

　　C. do

　　D. has

　　试题答案及解析：

　　6. D这是一个含蓄虚拟句，意为“有些妇女完全可以不呆在家里，干一份工作挣得可观的工资，可是她们决定不工作，为的是照顾家庭”，所以选D。should have made意思是“本应该做而实际上没做”，与原句意不够贴切。

　　7. B相当于A light with no more power than the power that is produced by…。that代替power，表示相比较的事物，而D中没有比较对象，故不对;as表示原级比较，不与than用在一起，故A也不正确;C中缺少that的先行词，也是错误的。

　　8. Clet alone，“更不用说……”，在用法上相当于并列连词，因此要求填入与前面一样的结构，此处是不定式。

　　9. D句子要求填一个能够代替these refrigerators 的代词，故排除A、C。the others一般与另一部分相对而言，在此句中不对，所以选the ones。

　　10. A句子后半句是倒装句，主语是复数its soil and the water of its lakes, rivers and oceans，因为较长，所以后置，故选A。

　　11. You _______ such a long essay; our teacher only asked for 200 words, and you have written 300!

　　A. but

　　B. because

　　C. as

　　D. in that

　　试题答案及解析：

　　11. Cneedn’t have done sth.表示做了不必做的事，此句意为：“你真不必写这么长的文章，老师告诉我们只写200个词，可你写了300个词。”

　　12. AB、C选项之所以错，主要是由于long的位置不对，应为：B. Being long used…;C Having long been used…。句子前半部分是状语，故D也不对。由此可见A是惟一正确的选择。

　　13. Cother than 的意思相当于except，常用在否定词之后，如nobody other than…，nothing other than等。本句中与no在一起连用，意为“只有在英国……”。it has been said是插入语。

　　14. Bas是关系代词，引导非限定性定语从句， 其先行词是measures，相当于…as the measures which are taken by the government…，其他几个词都是连词，不能引导定语从句。

　　15. A句中的第一个空白处需要一个引导名词性从句的关系代词，在从句中做write 的宾语;第二个空白处要填一个修饰way的定语从句的关系代词，因此只能选A。注意: 先行词是way, 引导定语从句的关系代词一定不能用how, 可以用in which, 可以用that, 也可以省略不用。

　　16. Cunless“除非”，从主从句的逻辑关系上看是惟一正确选择。句意：“假如发生了水灾或地震，且火车、汽车又无法通至灾区，除非用飞机空投，否则那里的人们就会饿死。”

　　17. Bto become在句中做desire的定语，意为“成为一个著名作家的愿望”，其他结构一般不做desire的定语。

　　18. B不定式to have been working…做主语scientist的补足语，用完成进行式表示：“这个科学家已对如此复杂的问题研究了大约十年，并且还要继续研究下去。”

　　19. Dtaken在句中做后置定语，修饰majority, 由于与所修饰的词是动宾关系，所以应用过去分词，a majority which is taken collectively可以理解为“(把)大多数人作为一个整体”。

　　20. A句中but表示转折，后面陈述的是事实情况：“……看错了问题所以没答对”。暗指“若不是看错了题，就会答对而且通过考试”。因此句子前半部分用的是虚拟语气would have passed。
