2019-2020年高中英语每日一题之快乐暑假第05天情态动词含解析新人教版必修 高考频度：难易程度：1. (xx北京) Samuel, the tallest boy in our class, _ easily reach the books on the top shelf.A. must B. should C. can D. need【参考答案】C【试题解析】考查情态动词。句意：Samuel，我们班最高的男生，能很轻松地够着书架顶上的书。表示能力，用can。【特别提醒】情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式是在情态动词后面加not。个别情态动词有现在式和过去式两种形式,，过去式用来表达更加客气、委婉的语气，时态性不强，可用于过去、现在和将来。情态动词没有被动语态。【归纳总结】can的用法：(1)表示一贯的能力。(2)表推测，只能用于否定句与疑问句中。can 用在肯定句中表示一时的可能性。(3)表示允许(和may意思相近)，常见于口语。(4)比较委婉、客气地提出问题或陈述看法。2.
