2017-2018学年人教版必修二Unit3 Section 3巩固提升含解析 Ⅰ.单句语法填空 1.The computer, __with__whose help we human beings have stepped into the information age,should be regarded as one of the most important inventions in the 20th century. 解析:先行词是computer,指物,关系词在从句中作help的定语,而关系词+help又作介词with的宾语,with前置。从句的意思是“在它(电脑)的帮助下,我们人类进入了信息时代。” 2.A completely new situation is likely __to arise__(arise) when the new law comes into effect. 解析:句意:当这条新法律生效时,一个全新的形势很可能会出现。be likely to do...“可能……”。 3.Over the past four years,the Chinese naval escort(海军护航队) has successfully watched __over__ more than 5,000 ships from China. 解析:句意:在过去的四年里,中国海军护航队成功保护了中国的5 000多艘船只。watch over照顾,保护。 4.Can you tell me __what__he is busy dealing with now? 解析:考查宾语从句引导词的用法。句意:你能告诉我他现在在忙于处理什么吗?动词短语deal with“处理”,后面应该跟宾语,所以使用能作宾语的引导词what。受定势思维的影响,此题易误填how。
