题目内容
8.-Tom is always careless with his schoolwork.Could you help him?-No problem!I think he _______ to think twice before starting.( )
| A. | should be told | B. | can tell | C. | should tell | D. | can be telling |
分析 --汤姆在功课上总是很粗心.你能够帮帮他吗?
--没问题.我想应该告诉他在开始前要先三思.
解答 答案:A
首先根据语境判断答语的意思是"没问题.我想应该告诉他在开始前要先三思."主语 he是动作tell 的承受者,表示"被告知",确定用被动语态,根据句意用情态动词should,含有情态动词的被动语态的构成是: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.
