一、 have fun doing sth.

【句型介绍】 意为\"做某事有乐趣\",其中have fun 相当于enjoy oneself,表示过得愉快。

八年级册1-7单元重点知识回顾

1. 英语中的集体名词,如family, class, team等作主语时,若作为一个整体看,其后的谓语动词用单数;若强调其组成成员,谓语动词用复数。如:

My family is a happy one. 我家是个幸福的家庭。

My family are all watching TV. 我们全家人都在看电视。

2. 在比较级中,要注意than后面人称代词的格。

1)当句子中的谓语动词是不及物动词时,than后面的代词用主格还是宾格,在意思上通常没有区别。如:

He runs faster than I / me. 他跑得比我快。

They get to school earlier than we / us every day. 他们每天都比我们到校早。

2)当句中的谓语动词是及物动词时,than后面的人称代词用主格还是宾格在意思上就有差别了。试比较:

I like you more than he. (=I like you more than he likes you.) 我比他更喜欢你。

I like you more than him. (=I like you more than I like him.) 你和他相比,我更喜欢你。

3. 不定式作定语时,应放在被修饰词的后面,一般指一个还没有发生的动作。如:

Do you have anything to say about this? 有关这件事你有没有什么要说的?

4. 在比较句型中,than后面的谓语动词常常省略。也可以用相应的助动词来代替与前面相同的谓语动词,以避免重复。如:

Tom does better at the lessons than I (do). 汤姆功课比我好。

She ate less than I (did) for breakfast. 她早饭吃得比我少。

5. You\'d better ... 是You had better ... 的缩写形式。 had better 为固定短语,意为\"最好......\",后接动词原形,常用来提出建议或劝告,其否定形式是\"had better not + 动词原形\"。如:

You\'d better not stay there too long. 你最好别在那里呆得太久。

We had fun playing computer games. 我们玩电脑游戏很愉快。

【句式比较】 have a good / nice / wonderful time doing sth. 做某事有乐趣

Did you have a good / nice / wonderful time visiting that country? 访问那个国家你们快乐吗?

【特别提醒】 句中fun为不可数名词,表乐趣,前面不能加不定冠词。

Unit 8 How was your school trip?

Grammar:

一般过去时:指在过去某一时间内发生的动作或存在的状态,常和表示过去意义的时间状语连用。如:yesterday, last year(week,month…),two years ago, in2006等。有时也可用when,after,before, as soon as引导的时间状语从句。该时态在句中的体现是谓语动词用过去式。谓语be动词→was/were 否定:wasn’t /weren’t

Be动词句型

一般疑问句:was/were +主语…

特殊疑问句:疑问词+was/were+主语

陈述句:主语+was/were+…(肯定句) 否定句:主语+wasn’t/weren’t+…

行为动词句型(当句中的动词为行为动词时,要借助动词did构成一般疑问句和否定句)

肯定式:主语+动词过去式

否定式:主语+didn’t+动词原形

一般疑问句:Did +主语+动词原形

特殊疑问句:Did+主语+动词原形

Unit 9 When was he born?

Grammar: 一般过去时的特殊疑问句

一般过去时的特殊疑问句的变法同一般现在时一样,不同之处在于须将be动词或助动词改为过去时态,即“特殊疑问词+were或was(第三人称单数)+主语+(表语)+其他成分”或“特殊疑问词+助动词did+主语+实义动词+其他成分。”

以when引导的特殊疑问句,对某人的出生年月进行提问,句型是:

When was/were…born? … was/were born in +时间

When was David beckham born? 大卫.贝克汉姆是什么时候出生的?He was born in 1975.

二.以how long 引导的特殊疑问句,对表示某一短时间的状语进行提问。句型是:

How long did + 主语+动词?

How long did Charles Smith hiccup? He hiccupped for 69 years and 5 months.

三.When did he start hiccupping? 他什么时候开始打嗝?When +did+主语+动词?

Unit 10 I’m going to be a basketball player.

3.be +v.ing The Greens are moving to another city the day after tomorrow.

Unit 11 Could you please clean your room?

Grammar:情态动词

情态动词,表示说话者对某一动作的看法和态度,包括可能、怀疑、允许、愿望、必要、猜测等。Can(能、会),may( 可以),must( 必须、一定)等。

情态动词的特点:(1)情态动词有一定词义,但不能单独作谓语,必须和另一个动词原形一起构成谓语,且没有人称和数的变化。1. I can speak English. 2. She must be a teacher. 3. We may go home now.

(2)变否定句时,直接在情态动词后面加not,无需加助动词。He can’t play the guitar well.

He can’t answer the question. You mustn’t be late.

(3)含有情态动词的句子变一般疑问句时,须将情态动词提前。Can you help me? Must I go there at once?

(4)can 可表示能力、允许、可能性、怀疑猜测,意为“能,会,可以。”can’t, 意为“不能,不会,不可以。”,还有“不可能”之意。

--Can you drive? ? Sorry, I can’t. It can’t be true.

(5)can 也可表示请求与邀请

Can you please sweep the floor?

Unit12 What’s the best radio station?

Grammar:形容词/副词的最高级,用于三者或三者以上的人或事物之间的比较,表示在一群人或事物中,其中一个 “最……”见课本p93语法

the +最高级 She is the tallest of all her classmates.

最高级可被序数词以及much, by far,nearly,almost, by no means, not quite,not really, nothing like等修饰。This hat is by far the biggest.

表示最高程度的形容词,excellent, extreme, prefect等没有最高级也不能用比较级。He is an excellent teacher.

形容词最高级间修饰做表语或介词并与的名词代词是,被修饰的词往往省略。

He is the youngest (boy) in his class.

Who/Which +be+最高级,A,B,or C? Who is the most useful, a bicycle, a motorcycle,or a car?

the +序数词+最高级 He is the second tallest student in our class.

One of the +最高级+复数名词 The Yellow River is one of the longest rivers in China.
