题目内容
15.The new online library makes possible for students to choose books by smart phone off campus.( )| A. | it | B. | one | C. | that | D. | this |
分析 新的网上图书馆使学生离开校园通过智能手机选择图书成为可能.
解答 答案选A.
这里使用了句型"make it+adj.+for sb.to do sth.",意思是"做…事情对某人来说是…",这里的it是形式宾语,to choose books by smart phone off campus是真正的宾语,其他三个选项都不能做形式宾语,故选A
点评 it在句中可以做形式主语或形式宾语,真正的主语或宾语通常为动词不定式或that从句或动名词.
例如:It is not right to use these places as rubbish dumps.把这些地方用来倒垃圾是不对的.(it用作形式主语,真正的主语为动词不定式)
It was clear that they had no desire for peace.很清楚他们没有和平的诚意.(it用作形式主语,真正的主语为that从句)
Do you consider it any good trying again?你觉得再试会有好处吗?(it用作形式宾语,真正的宾语为动名词)
