单元清祈使句1祈使句的定义。用于表达命令、请求、劝告、警告、禁止等的句子叫作祈使句。2祈使句的用法。肯定祈使句以动词原形开头。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。【注意】祈使句因对象(即主语)是第二人称，所以通常都省略主语。3祈使句句型结构。(1)肯定结构：Do型即：动词原形(宾语)其他成分Please have a seat here.请这边坐。Be型即：Be表语(名词或形容词)其他成分Be a good kid！要做一个好孩子！Let型(即：let宾语动词原形其他成分)Let me help you.让我来帮你。(2)否定结构：Do型和Be型的否定式都是在句首加dont。Dont be late for school！上学不要迟到！Let型的否定式有两种：Dont let宾语动词原形其他成分；Let宾语not动词原形其他成分。Dont let him go./Let him not go.别让他走。写作案例假如你是Tom，请根据邮件内容及所给信息，给王刚回一封电子邮件。Dear Tom，How are you?Im writing to ask you something about cooking.My good friends want to spend this weekend with me.I want to make fruit salad for them.But I dont know how to make it well.Can you help me？Please tell me what I need and what I should do.I hope to hear from you as soon as possible.Yours，Wang Gang原料：四根香蕉，三个苹果，半个西瓜，或者其他水果，蜂蜜，奶酪。步骤：全部切碎放在碗里面；加蜂蜜和奶酪；搅拌均匀。思路点拨这是一篇关于物品的制作流程的文章。我们在写作时，先写原料和设备；再写制作流程，写流程可运用表示步骤的first，next，then与finally等词汇；最后写出评价和总结。高分模板引出话题：want to make fruit salad，need four bananas，three apples，and a half watermelon.制作好后的感受：.enjoy it with your friends.美文欣赏Dear Wang Gang，Im glad to hear from you.You want to make fruit salad.You need four bananas，three apples and a half watermelon or other fruits，and you also need some honey and yogurt.First，wash and cut up all the fruits，and put them into a bowl.Next，add two spoons of honey and a cup of yogurt to the fruit.Then，mix up everything.Finally，serve the fruit salad an
