英语六级考试攻克语法的必备练习(17)

　　汉英

　　必做：

　　1._______that Jack has returned.

　　2._________is a basic assumption of social scientists.

　　选做：His ability has never been in doubt,but the question is________

　　答案及解析

　　1.It is evident

　　【解析】该题考点为主语从句后置，句首it充当形式主语

　　2.That nearly all behavior is learned behavior

　　【解析】该题考察主语从句的用法。主语从句需有连接词that引导，且不能省略

　　选做：whether he is prepared to work hard

　　【解析】该题考察表语从句的使用，前文中表示never in doubt,即为肯定之意，而后文中用but转折，表示与前文不一样的感情色彩，即有些怀疑，所以应用表示不确定的引导词whether或if;由于if不能用在表语从句中，故只有使用whether.

　　c)To be judged the best d)Having judged the best

　　6.a)had been fulfilled b)were fulfilled

　　c)been fulfilled d)having been fulfilled

　　答案及解析

　　1. 选c。该题考察过去分词短语作后置定语的用法。观察句子可以看出Professor Wang与动词know间为被动关系，所以要用动词过去分词形式作后置状语，修饰Professor Wang, known for sth意为以而著称/闻名

　　2. 选a。该题考察with+名词+介词结构作伴随状语的用法。

　　3. 选a。该题考察不定式的用法。动词不定式to translate这一动作发生在谓语动作之前，而且该动作的客体是本句的主语，所以应当用完成式被动态。in the last decade这个时间状语也提示应选择不定式的完成式。

　　4. 选c。该题考察动名词的用法。观察句子结构可以看出这里需要构成一个表达式作句子的主语，由于review与主句谓语give us a much better feel 同步发生，所以用一般时而不用完成时，reviewing their work是动名词短语作主语。

　　5. 选b。该题考察非谓语动词分词作状语的用法。根据句意确定这句应选分词短语做原因状语，而且考虑到分词短语与主句中主语的逻辑关系是被动关系，所以选b

　　6. 选d。该题考察分词独立结构。根据句子语义结构判定前后表达非并列关系，因而应选非谓语的表达，而且由于fulfill与all the tasks是被动关系，而且发生在谓语动词之前，因此用现在分词的完成被动式。
