题目内容
18.The stones are so heavy.How they to the top of the building without modermachines?( )
| A. | do; lift | B. | did; lift | C. | were; lifted | D. | were; lift |
分析 这些石头太重了,在没有现代机器的情况下,它们是如何被搬到建筑物的顶端的?
解答 答案:C.
根据语境推测句意是"这些石头太重了,在没有现代机器的情况下,它们是如何被搬到建筑物的顶端的?"句子表述的是过去的事情,判断句子中的谓语动词用一般过去时,主语they(the stones)是动作lift的承受者,所以用被动语态,一般过去时被动语态的构成是:主语+was/were+动词的过去分词,故选C.
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.
