祈使句

在英語(yǔ)中，用于表達(dá)命令、請(qǐng)求、勸告、警告、禁止等的句子叫祈使句。祈使句通常省略主語(yǔ)(you)，句首動(dòng)詞用原形。祈使句一般沒(méi)有時(shí)態(tài)的變化，也不能與情態(tài)動(dòng)詞連用。學(xué)習(xí)理解類活動(dòng)1.以實(shí)義動(dòng)詞原形開(kāi)頭。e.g.Comehere.

Lookatthemap.2.以動(dòng)詞be開(kāi)頭。e.g.Beagoodboy.

Bequiet,please.3.以Let開(kāi)頭。e.g.Letmehavealook.

Let’sgo!有時(shí)可在祈使句的句首或句尾加上please，使語(yǔ)氣顯得客氣、有禮貌。如果在句尾加please，應(yīng)該用逗號(hào)與前句隔開(kāi)。e.g.Comein,please.肯定式No+名詞/動(dòng)詞-ing形式表示禁止或規(guī)勸，常用于公共場(chǎng)所。e.g.Nophotos!

Nosmoking！

否定式4.在動(dòng)詞原形前加don’te.g.Don’tsithere.Don’tbelate.5.以No開(kāi)頭的祈使句。eg.
