Unit5 Topic2 知识点归纳一．语法：1.同级比较A+ be+ as+ adj.原级+ as+ B: Helen is as tall as Maria.A+ be+ not + as/so+ adj原级+ as + B: Helen isn’t as tall as Maria.A+V+as+adv原级+as + B: Helen runs as quickly as Lily.A+don’t/doesn’t/didn’t+V原+as/so+adv.原级+as + B:Helen doesn’t sing as/so well as Lucy.\注：①无论是肯定结构as…as…还是否定结构not as/so…as..，中间都用adj/adv 原级。

②谓语若是be,则用adj.原级；谓语若是v.,则用adv.原级。

2.原因状语从句：表示主句所发生的原因或理由，通常由because, as, since 等词引导。

e.g. Because I lost my cellphone, I didn’t call you yesterday.Since you are so young, you should be modest.既然你这么年轻，就应该谦虚一点。

1.because语气最强，用于回答why的提问，从句可放于句首，也可放句尾，想强调什么，就把什么放在句首。

e.g. He didn’t come to school because he was ill.他没去上学，是因为他病了。

Because they asked me to do it, I did it.因为他们要我做，所以我做了。

2. as 和since 语气较弱，用来表示非常明显的原因或者对方已经了解的原因，引导的从句一般要放在句首。

e.g. As he knew nothing about the matter, he kept quiet during the meeting.因为他对此事一无所知，所以在会上什么也没说。

Unit5 Topic3 知识点归纳一．语法：简单句的六种基本结构1.主语+系动词+表语（S+ Link.V+P ）说明主语的特征、类属、状态、身份2.主语+谓语（S + V)句子的谓语动词能表达完整的意思。

这类动词叫做不及物动词，后面可以跟副词、介词短语、状语从句等。

3.主语+谓语+ 宾语（S + V + O)谓语动词都具有实义，都是主语产生的动作，但不能表达完整的意思，必须跟有一个宾语，即动作的承受者，才能使意思完整。

这类动词叫做及物动词。

4.主语+谓语+ 间接宾语+直接宾语（S + V + O + O）谓语动词必须跟有两个宾语才能表达完整的意思。

这两个宾语一个是动作的直接承受者，另一个是动作的间接承受者。

通常这一间接承受者用一个介词来连接，当动作的间接承受者在动作的直接承受者之前时，这一介词往往被省略。

5.主语+谓语+ 宾语+宾语补足语（S + V + O + C）动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整。

6.There be 句型表示：在某地有某物（或某人）二．单词短语1.affect feelings 影响心情2.have a test 测试3.give a speech 演讲4.hate to do =hate doing讨厌做某事5.follow one’s advice遵从某人的建议get well=become well 康复6.must be----肯定推测；can’t be---否定推测e.g. The boy must be Jim. This book can’t be Jim’s.7. fall off= fall down from 从-----摔下来8. take turn s to do轮流做某事：We take turns to sing songs.in turn轮流：We sing songs in turn.It’s one’s turn to do轮到某人做某事：It’s my turn to clean a room.9. be ill in bed卧病在床 e.g. Li Ming is ill in bed.10. It’s +adj.+ for sb. + to do: It’s important for me to study well.It’s +adj. + of sb. + to do: It’s nice of you to help me.注：若adj.用来修饰人的性格、品质，则用of，若adj.用来修饰to do,则用for。

八下unit 5 topic 2 I feel better now.1.be sorry to do sth.很抱歉做某事例：I’m sorry to keep you waiting so long.很抱歉让你等那么久。

2.do badly in…在…方面做得不好，badly是副词，修饰动词的副词通常放在被修饰的动词之后。

如：listen carefully, read quickly等。

反义词组：do well in…例：Why do you think you did so badly in your text?你认为为什么你考得这么差？He did very well in English when he was young.他小时候就很擅长英语。

3.be strict with sb.对某人要求严格例：The teacher is strict with us.老师对我们要求严格。

be strict about/in sth.在某方面要求严格例：His father is strict with him about/in study.他的父亲在学习方面对他要求很严格。

例：Mary, I can’t go there with you, because I have a lot of homework to do.玛丽，我不能和你去那儿，因为我有许多家庭作业要做。

5.have a talk with sb.和某人交谈，talk在这里是名词，这个短语相当于talk with sb.例：You should have a talk with your son to know what he is thinking about. = You should talk with your son to know what he is thinking about.你应该和你的儿子谈一谈，弄清楚他在想什么。
