题目内容
7.---Do you know who invented the telephone?---No.I only know it ________________ in 1876.( )
| A. | invented | B. | was invented | C. | invents |
分析 --你知道电话是谁发明的吗?
--不,我只知道电话是1876年发明的.
解答 答案:B.
首先根据时间状语 in 1876,判断句子中的谓语动词用一般过去时,主语it(the telephone)是动作invent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,主语是it,be动词用was,故选B.
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.
