选择题
The stones are so heavy. How _____ they _____ to the top of the building without modern machines?
A.do; lift
B.did; lift
C.were; lifted
D.were; lift
答案
答案:C
题目分析:句意:那些石头那么重。没有现代的机器他们怎么被举到那个建筑的顶部的?被动语态表示主语是动作的承受者,即行为动作的对象。例如:English is spoken by many people.主语English是动词speak的承受者。被动语态由“助动词be+及物动词的过去分词”构成。一般过去式的被动语态构成was/were+taught,lift的过去分词为 lifted,肯定句变疑问句,如果肯定句有be把be动词提前。根据语境故选C.
