高考情态动词练习题及答案详解一、单项选择情态动词1．Look! There are so many mistakes in your composition. You ________ have fixed full attention on it.A．can B．shouldC．need D．might【答案】B【解析】【详解】考查情态动词。
句意：看！你的作文里有那么多的错误。
你本应该把所有的注意力都集中在它上面的。
表示“本应该做但实际上没有做”应该用should have done结构，can have done 表示可能；need表示需要；might have done表示可能做过某事；故选B。
2．—I don’t really like Janes. Why did you invite him?—Don’t worry. He come. He said he was’t certain what his plans were.A．must not B．need not C．would not D．might not【答案】D【解析】考察情态动词，题干中的h e wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。
3．-- Did Jim come?-- I don’t know. He _______ while I was out.A．might have come B．might comeC．must have come D．should have come【答案】A【解析】【详解】考查情态动词推测用法。
句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。
根据前文I don’t know.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。
对过去情况的推测为情态动词+have done，must have done 一定做了某事，should have done 应该来过，不符合，故选A。

A．canB．needC．mustD．will
考点：考查情态动词用法
点评：考本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事；shouldn’t have done本不应该做而实际做了。need have done本有必要做某事；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。
中国学生的常见病句是：They...; they certainly have arrived.病句的句义是“他们当然已经到达了。”（这不是对过去的肯定推测，而是断定动作已经完成。）
11．According to a newly released regulation on online video services, no one _____ generate, release or spread fake news or information by using such technologies.
Somebody must have stolen the ring.肯定有人偷了这枚戒指. [该句所推断的偷窃动作发生在过去.]
