题目内容
15.Each year quite a lot of food ______ around the world.It's really time for us to do something.( )| A. | was wasted | B. | is wasted | C. | wasted | D. | will be wasted |
分析 每年全世界许多食物被浪费.我们该做些事情了.
解答 答案:B 根据这句话的主语quite a lot of food是动词waste的承受者,从而构成被动的关系,应该用被动语态.,根据句中的时间each year可知,应该用一般现在时.也就是一般现在时的被动语态,一般现在时被动语态的构成is/am/are+及物动词的过去分词,故选B
点评 在做此类谓语动词的题目时,首先要找出时间标志或隐含的语境,判断时态,然后根据主语和谓语动词的关系,判断其语态是主动还是被动,若能充分利用这些时态标志,同时结合句子语境,就可很快选出正确答案
