2025年中考英語(yǔ)易犯錯(cuò)的語(yǔ)法：情態(tài)動(dòng)詞

　　  七. 情態(tài)動(dòng)詞  

　　41．He can be at home now because the light in his room is still on.

　　表特別有把握的肯定判斷時(shí)用must，表特別有把握的否定判斷時(shí)用can, can表判斷時(shí)只用在否定句中。因此把can 改為must。

　　42．He need come here before the meeting begins.

　　作情態(tài)動(dòng)詞時(shí)need用在否定，疑問(wèn)和條件句中，不能用于肯定句中，而作實(shí)意動(dòng)詞時(shí)則可以。所以應(yīng)改為：He needs to come here before the meeting begins.

　　43．He used to get up very early in the morning, and now he is still doing so.

　　used to 用來(lái)表示過(guò)去常常做某事而現(xiàn)在不了，所以應(yīng)把后半句改為：but now he is not doing so.

　　44．I needn’t come yesterday because all the work had been finished.

　　由于情態(tài)動(dòng)詞本身不體現(xiàn)時(shí)態(tài)，所以在談?wù)撨^(guò)去的事情時(shí)在情態(tài)動(dòng)詞后加 have done，因此在 needn’t 后加have。

　　45．You hadn’t better stay up too late because you have to get up early tomorrow.

　　had better 的否定在 better 后面加not.
