Step1 Language practice 观察Language practice下方的句子，并试着总结黑体部分的规律。 结论：一、祈使句 1.定义:用于表达命令、请求、劝告、警告、禁止等的句子叫祈使句,祈使句最常用于表达命令,因此也常称为命令句。 2.句型 (1)Do型:动词原形(+宾语)+其他成分 Please have a seat here.请这边坐。 有的祈使句在意思明确的情况下,动词可省略。 This way,please.=Go this way,please.请这边走。 (2)Be型:Be+表语(名词或形容词)+其他成分 Be a good boy!要做一个好孩子! (3)Let型:Let+宾语+动词原形+其他成分 Let me help you.让我来帮你。 【注意】 在标志牌上,常用“No+动名词/名词”构成简略的否定祈使句。 No smoking!禁止吸烟! No parking!禁止停车!No photos!禁止拍照! 对句子中涉及的语法进行点拨讲解。
