题目内容
9.-We should do what we can _____ the endangered animals.--Yes,it's duty_____ them.( )
| A. | save,to protect | B. | save,protect | ||
| C. | to save,protect | D. | to save,to protect |
分析 --我们应该做我们能做的来拯救频临灭绝的动物.
--是的,保护他们是我们的责任.
解答 答案:D.
save的意思是"挽救,拯救";protect的意思是"保护".动词不定式经常用来作目的状语,还可以作主语,作主语的时候,经常用it作形式主语,把不定式放在后面.在"We should do what we can _____"中"what we can"是宾语从句,作前面动词do的宾语,这句话的意思是:我们应该做我们能做的来拯救频临灭绝的动物.所以要用动词不定式来作目的状语.又根据"it's duty_____ them"结合给出的选项protect,可知保护他们是我们的责任,在此处用动词不定式作主语,而用it作形式主语,综上所述,故选D.
点评 首先要掌握动词不定式的用法,然后结合具体的题目,就可以确定正确答案.
