英语情态动词练习题20篇及解析

英语情态动词练习题20篇及解析 一、单项选择情态动词 1．—________ the woman with the baby come over? We have a seat here. —Thank you, sir. Actually I do have my seat here. But my baby likes to look out of the window. A．Would B．Shall C．Must D．May 【答案】A 【解析】 【详解】 考查情态动词。句意：——那位抱小孩的女士，要不来这边吧?这儿有个座位。——谢谢，实际上我有座位的，只是我的孩子喜欢看窗外。would表示婉转的请求，征求对方的意见，Shall提问一般只用于第一人称，我们常说Shall I.或者 Shall we；may表示请求对方允许。故选A。 【点睛】 would的用法 1.would 最常见的用法是：相对于一个过去时间点的后来“将要”做什么，比如：He said he would meet me at the station. 他说他会在车站接我的。这句中的 would meet 是相对于 said （过去说）之后要做的事情。又如：She thought she would have to ask someone for help. 她当时想，她得找个人帮忙。 2．Students ____ remain in their seats until all the papers have been collected according to the regulation. A．would B．shall C．will D．could 【答案】B 【解析】 【详解】 考查情态动词。句意：学生们必须呆在自己的座位上，直到所有的试卷都被收回。根据句意，“学生们呆在自己的座位上”是一项规定。shall 可表示某种规定或义务，用于第二、三人称的句子中。而其他情态动词无此用法。故正确答案为B。 3．Most of the top leaders expressed a common desire at the UN conference, ______ that different cultures ______ coexist with tolerance. A．the one ; must B．the one ; should C．one ; must D．one ; should 【答案】D 【解析】 【详解】 考查替代和情态动词。句意：大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。替代表泛指的单数名词，通常用one替代。此处用
