2._____ is necessary for us to tell him about the result.( )A. | That | B. | This | C. | It | D. | What |
分析 我们有必要告诉他结果.
解答 答案:C
根据题干分析可知,句子真正主语为to tell him about the result,如果放在开头显得"头重脚轻",为使句子保持平衡,借助于"it"做形式主语,构成句型:It is adj.for sb to do sth…意为"对某人来说做某事…";注意,只能使用it做形式主语,其他词均不可以.
点评 本题考查it做代词的用法,属于固定句型,考生需要熟练掌握基本句型.
