题目内容
3.Now all Chinese couples______to have two children.( )| A. | allow | B. | allowed | C. | are allowed | D. | were allowed |
分析 现在所有的中国夫妇允许生二胎.
解答 答案:C.
首先根据 句意"现在所有的中国夫妇允许生二胎.",判断句子表述的是现在的客观事实,所以用一般现在时,主语 all Chinese couples是动作 allow的承受者,表示"被允许"所以用被动语态,一般现在时被动语态的构成是:主语+am/is/are+动词的过去分词,主语是复数名词,be动词用are,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.
