【小编编语】今天查字典英语网小编教给同学们的是初中英语祈使句结构,一起来学习下吧!
祈使句
用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句,祈使句通常省略主语,谓语动词用原形,句尾用感叹号或句号。
1、肯定结构:
1)动词原形(+宾语)+其它成分。如: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。如:This way, please. = Go this way, please. 请这边走。
2)Be + 表语(名词或形容词)+其它成分。如:Be a good boy! 要做一个好孩子!
3)Let + 宾语 + 动词原形 + 其它成分。如:Let me help you. 让我来帮你。
2、否定结构:
1)don't+动词原形+其他。如:Don't forget me!不要忘记我!Don't be late for school!上学不要迟到!
2)Let + 宾语 + not + 动词原形 + 其它成分。如:Let him not go. 别让他走。
3)有些可用no开头,用来表示禁止性的祈使句。如:No smoking!禁止吸烟!
常见考法
对于感叹句和祈使句的考查,常会出现在单选和完成句子中,主要考察两种句子的用法和构成。
典型例题:You should not talk in class.(改写同义句)
in class.
解析:本题考查祈使句的用法。从题意“你不应该在课堂上说话可知,这是建议对方不要做某事的,应该用祈使句。
答案:Don't talk
误区提醒
感叹句中what 和how的用法区别,是很多学生头疼的地方,实际上区分它们并不难,只要记住:有形容词直接加名词的地方,或只有名次的地方,用what,反之用how.
典型例题:____ strange clothes he is wearing!
A. What a B. What C. How a
解析:题中strange clothes是形容词直接加名词构成的名词短语,应该用what,clothes是不可数名词,不能加a.
答案:B
