情態(tài)動(dòng)詞can

特殊疑問(wèn)句。

表示疑問(wèn)，有疑問(wèn)詞(在開(kāi)頭)，回答有很多種可能。

常用疑問(wèn)詞：

What、When、Which、Who、Whose、Why、How

如何對(duì)劃線部分提問(wèn)：

1、將原問(wèn)句翻譯為漢語(yǔ)(在讀中要將劃線部分重讀)。

如：His birthday is on the 5th of May .

他的生日在五月五日。

2、用漢語(yǔ)進(jìn)行提問(wèn)。

如上句，應(yīng)該問(wèn)：他的生日在什么時(shí)候?

3、根據(jù)漢語(yǔ)將所要提問(wèn)的句子補(bǔ)充完整。

如上句When is his birthday ?

四、祈使句

表示請(qǐng)求或命令別人做某事或不要做某事。

肯定祈使句一定是以動(dòng)詞原形開(kāi)頭(有時(shí)有please)，否定的祈使句一定是don’t加動(dòng)詞原形開(kāi)頭(有時(shí)有please)。

把祈使句改為否定句只需在動(dòng)詞前加don’t即可。
