题型:不详难度:来源:
It is necessary _____ something to protect our environment. |
答案
B |
解析
试题分析:此题重点考查固定句型,It is+形容词 for sb. to do sth,“表示做某事对某人来说很adj”在这个结构中,it是形式主语,真正主语是后面的不定式短语,因此排除A、C、D故选B 点评:It is +adj+for sb to do adj应该是对做这件事的评价,该题常常考查不定式,很多同容易出错,同时还要加以区分It is+adj+of sb to do sth adj应该是对这个人做这件事的评价,adj多用形容人的 |
