高中英语情态动词常见题型及答题技巧及练习题(含答案)
高中英语情态动词常见题型及答题技巧及练习题(含答案)一、单项选择情态动词1．The professor warned the students that on no account ________ use mobile phones in his class.A．should they B．they shouldC．dare they D．they dare【答案】A【解析】【详解】考查部分倒装和情态动词。
句意：这位教授警告学生们，在他的课堂上，决不应该使用手机。
on no account意为“决不”，否定词放在句首，句子使用部分倒装，排除B、D项；这里表示应该，故选A。
2．—Did you attend the meeting for the experiment project yesterday?—Yes, but I don’t think I ____ because my director was there.A．need to have B．need to C．needed to D．need have【答案】D【解析】【分析】【详解】考查情态动词+have done。
句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。
Think/suppose等宾语从句中如果有否定词时，要把从句的否定词not前移，即“否定前移”。
所以not是从句中的否定词。
“need have done”意为“本来有必要做而未做”；“needn’t have done”指过去本来没必要做而做了。
根据上一句时间状语“yesterday”可知本句指的是过去发生的事。
结合第二句“because my director was there(我的主管)在”可推断出，我本来不必要去。
故选D。

高中英语情态动词经典习题(含答案)

1．-- Catherine, I have cleaned the room for you.
---Thanks. You _______ it. I could manage it myself.
A．needn’t doB．shouldn’t have doneC．mustn’t doD．needn’t have done
【答案】D
【解析】
【详解】
考查情态动词辨析。句意: ---凯瑟琳，我已经为你打扫了房间。- - -谢谢。你本不必这么做的。我自己能行。A. needn’t do不必做某事；B. shouldn’t have done本不应该做某事；C. mustn’t do禁止做某事；D. needn’t have done本不必做某事。由“Thanks. I could manage it myself”可知，needn’t have done“本不必做某事，而实际上做了某事”符合句意。故选D项。
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.]
The temperature must have dropped to below zero last night, because the water is frozen all over.昨夜的温度肯定降到零度以下，因为水都冻住了。
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。）

考查情态动词。句意：-不好意思，我把窗户打开你介意吗?-好吧，如果你必须这么做的话。我可以多穿点衣服。A. can能够；B. may可能；C. must一定；必须；D. shall会；将。must表示偏要，必须要做的事情，故选C。

They started early this morning; they must have arrived by now.他们今晨很早就出发了，现在肯定已经到了。

would的用法
