人教版八年级下册英语Unit 4 知识点语法归纳总结

Unit 4 Why don’t you talk to your parents?1.短语归纳2.典句必背3.用法集萃(1)My parents don't allow me to hang out with my friends. 我的父母不允许我和我的朋友们出去闲逛。

❖allow作动词，意为“允许；准许”。

allow sb. to do sth. 意为“允许某人做某事”，也可以是allow sb. sth.例：His parents won't allow him to stay out late. 他的父母不允许他在外面待到很晚。

Each passenger is allowed 20 kilograms of baggage. 每位旅客准许携带20千克行李。

❖allow sb. to do sth.的被动结构是：“sb. be allowed to do sth.” 某人被允许做某事例：We are allowed to choose our own clothes. 我们被允许选择自己的衣服。

The children are not allowed to play on this lawn. 孩子们不准在这块草地上玩耍。

(2)What’s wrong?怎么了?❖wrong作形容词，意为“有毛病的；错误的”例：There’s something wrong with my bike. 我的自行车出毛病了。

I’m sorry to tell you that your answers are wrong. 我很遗憾地告诉你，你的答案错了。

❖拓展：wrong的延伸(3)I’m really tired because I studied until midnight last night.我真的很累，因为我昨天晚上一直学习到半夜。

❖because是连词，意为“因为”，引导原因状语从句。

人教版英语八年级下册第四单元知识点总结

人教版英语八年级下册第四单元知识点总结Why not…?/why don’t you…?用法Why not…?意为“为什么不……呢？”后跟动词原形，表示建议，相当于Why don't you do…?另外，Why not? 意为“好啊，为什么不呢？”是交际用语，表示同意对方的提议。

如：Why not go for a walk?为什么不去散步呢？Why don't you help your parents do housework?你为什么不帮你父母做家务呢？-Let' go to the beach.-Why not?-我们去海滩吧。

-为什么不呢?till / until在表达方式和意义上的特殊性：until是till的强调形式，但是它们表达的意义是相同的，都表示“直到某时”。

不过，在否定句中，它引出的意思是“直到（某时）（某动作）才（发生）”，这时候常会出现“not…until/till…”的结构。

例如：They didn't notice their mistakes till we pointed them out to them. 直到我们指出了他们的错误，他们才意识到。

但是，在肯定句中，它引出的意思是“直到（某时某动作停止了）”。

例如：The students made much noise till the teacher came into the classroom.直到老师走进教室学生们才停止了大声喧哗。

另外，until可以放在句首而till则不行。

我们只能说：Until they used up all their money, the young couple were very happy. 在他们花光他们所有的钱之前，这对年轻夫妇都很开心。

这两个词意义相同。

肯定形式表示的意思是“做某事直至某时”，动词必须是延续性的。

否定形式表达的意思是“直至某时才做某事”,动词常为非延续性动词。
