题目内容
7.---It's difficult for the village children to cross the river for school.---I think a bridge ________ over the river.( )
| A. | should be built | B. | be built | C. | should built |
分析 --对村子里的孩子来说过河去上学太难了.
--我认为应该在河上建一座桥.
解答 答案:A.
首先根据语境推测答语的句意是"我认为应该在河上建一座桥.",主语 a bridge 是动作build 的承受者,确定用被动语态,结合句意用情态动词should,说明本题考查含有情态动词的被动语态,其构成是:主语+情态动词+be+动词的过去分词. 故答案为:A
点评 本题考查时态和语态.每个时态都有标志词,熟记这些标志词是做题的关键.在没有时间状语的情况下可以根据语境来对时态做出判断.判断语态的关键则是观察主语是谓语动词的执行者还是承受者.
