【例题】—Most students in my class exercise every day
—Great. I should learn from them.
A . are doing B . did C. does D .do
【答案】D
【解析】句意:——我们班大多数学生每天都做运动。——太棒了。我应该向他们学习。考查动词时态。根据every day可知,此句是一般现在时,主语students是复数形式,动词用原形,故选D。
【例题】It's true that light much faster than sound.
A .travels B . travelled C.was travelling D . is travelled
【答案】A
【解析】句意:光的传播速度确实比声音快得多。考查动词时态。因为“光的传播速度比声音快得多”是一个客观事实,所以用一般现在时,谓语动词用三单形式。故选A。
