题目内容
3.It's difficult _______and the dust makes me ill.( )A. | to breathe | B. | breathing | C. | to be breathed | D. | breathe |
分析 呼吸困难;灰尘使我生病.
解答 答案选择A.本题考查动词不定式做状语.英语中做表语和补语的形容词后往往接动词不定式做状语,并且可用主动形式表示被动的含义;句中需要的是动词不定式做表语difficult的状语,所以答案选择A.
点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.
