祈使句

在英语中，用于表达命令、请求、劝告、警告、禁止等的句子叫祈使句。祈使句通常省略主语(you)，句首动词用原形。祈使句一般没有时态的变化，也不能与情态动词连用。学习理解类活动1.以实义动词原形开头。e.g.Comehere.

Lookatthemap.2.以动词be开头。e.g.Beagoodboy.

Bequiet,please.3.以Let开头。e.g.Letmehavealook.

Let’sgo!有时可在祈使句的句首或句尾加上please，使语气显得客气、有礼貌。如果在句尾加please，应该用逗号与前句隔开。e.g.Comein,please.肯定式No+名词/动词-ing形式表示禁止或规劝，常用于公共场所。e.g.Nophotos!

Nosmoking！

否定式4.在动词原形前加don’te.g.Don’tsithere.Don’tbelate.5.以No开头的祈使句。eg.

Digahole.Putthetreeinthehole.Putthesoilbackintothehole.Waterthetree.It’sOKnow.Let’slearnhowtoplanttrees.Doyouknowhowtoplantatree?howtoplantatree是“疑问词+动词不定式”结构，在句中作know的宾语。动词不定式常与what,how,where,when等疑问词连用，在句中作主语、宾语、表语等。Whentostartisnotdecidedyet.什么时候动身还没有决定。Idon’tknowhowtousethismachine.我不知道如何使用这台机器。Thequestioniswhattodonext.问题是下一步做什么。学习理解类活动“疑问词+动词不定式”结构的常见考点：Idon’tknowwhattodonext.我不知道接下来应该做什么。①同义句转换=Idon’tknowwhatIshoulddonext.②

动词不定式的动词后面是否需要宾语。Idon’tknowwhattodo.我不知道做什么。Idon’tknowhowtodoit.我不知道怎么做。what是连接代词，可作do的宾语，所以不能再加it；how是连接副词，作状语，所以需要it作do的宾语。学习理解类活动1、用祈使句表达说话者的要求:2、用“first,next,then…”等来表达顺序:Peelthebananas.Pourthemilkintotheblender.First,...then…;next…;finally…

3、用“howmany,howmuch”对名词数量提问
