题目内容
5.-We had to walk to school two years ago,but now we can take the subway.-Things always______.( )
| A. | changed | B. | have changed | C. | had changed | D. | change |
分析 --两年以前我们必须步行去上学,但现在我们可以乘坐地铁了.
--事情总是在变化的.
解答 答案:D.
根据设空处所在句子的句意:事情总是在变化的.和句子中表示频率的副词always,判断句子表述的是事物的一般特性,所以用一般现在时,主语things是复数名词,所以谓语动词用动词原形;故选D.
点评 本题考查了动词的时态.做题时,一定要特别关注有关的时间短语,这是判断句子时态的标志.在没有时间状语的情况下可以联系上下文根据语境来做出正确判断.
