初二上英语(新目标)各单元知识点总结

U1 where did you go on vacation?

1.短语:

decide to do决定

decide on/upon

feel like

2.语法:一般过去时

口诀:过去式之歌

过去式构成有方法,一般词尾加ed。

如果词尾有个e,直接加d就可以。

辅音字母y在尾,变y为i加ed。

“一辅重闭”作尾巴,双写之后ed加。

标准过去式加ed,少量不规则分别记。

am和is对was,are要变were没问题。

have和has用had,do和does变did。

一般过去时表示过去某个时间发生的动作或存在的状态。常和表示过去的时间状语连用。如:last year, yesterday等;也可表示过去经常反复发生的动作,常和often, always等频率副词连用。

1.一般过去时的形式:

动词be: 第一人称单数和第三人称单数用was, 其余的人称一律用were。

动词have: 一律用had, 没有人称和数的变化。

行为动词:一律用过去式,没有人称和数的变化,行为动词的过去式有两类,一类是规则动词,另一类是不规则动词。

3. 复合不定代词

something, somebody, someone, anything, anybody, anyone, nothing, nobody, no one, everything, everybody, everyone 等。

(1)它们在句中可用作主语、宾语或表语,但不能用作定语。

(2)something, someone 等和 anything, anyone等的区别与 some 和 any 的区别一样,前者一般用于肯定句,后者一般用于否定句、疑问句或条件句。具体使用时应注意以下几个语法特点:

特点1 其定语修饰语的位置:复合不定代词受定语修饰时,定语应放在它们后面。如:

There is nothing wrong with the radio. 这收音机没有毛病。 Have you seen anyone [anybody] famous? 你见过名人吗?

特点2 复合不定代词与指示代词:指人的复合不定代词若用作主语,其谓语动词一般用单数,相应的人称代词和物主代词也用单数 he, him, his (不一定指男性)。但在非正式文体中常用复数代词 they, them, their。如:

If anybody comes, ask him [them] to wait. 要是有人来,让他等着。

指事物的复合不定代词若用作主语,谓语动词只能用单数,相应的人称代词也只能用 it,而不用 they。如:

Everything is ready, isn’t it? 一切都准备好了,是吗?

特点3 其后是否接of短语:anyone, everyone 等只能指人,不能指物,且其

后一般不接of 短语。若是指物或后接 of 短语,可用 any one, every one (分开写)。如:

any one of the boys (books) 孩子们(书)当中的任何一个(本) every one of the students (schools) 每一个学生(一所学校)

4.enough 形容词副词前,to do 后

5. few, a few, little, a little 虽然都表示“少”,但

(1)few, a few是可数的, little, a little是不可数的。

(2)a few, a little含肯定意味,few, little含否定意味。这里所谓的“肯定意味”和“否定意味”应该这样来理解:同样是半杯水,口渴者会认为:There is little water in the glass. 而不口渴的人则会认为:There is a little water in the glass.

6. because 是连词,其后接句子;

because of 是复合介词,其后接名词、代词、动名词、what 从句等

how many 多少,用来提问可数名词数量;

how much 多少 用来提问不可数名词的数量或价格等。

2. Here are the results of the activity survey of Green High School.

本句为倒装句

here, there, out, in, up, down等副词开头并起强调作用时,可采用倒装结构,将副词置于句首,主谓语交换位置就好。其中主语须为名词,谓语的单复数形式由名词的数来决定。

结构:Here+谓语+主语

Here comes a bus.

Here are some apples.

▲当主语为代词时,不需要倒装,即谓语动词仍放在主语之后。

Here you are.

Here it is.

3.most 的用法:

(1)most作形容词直接用于名词前作定语,意为“大多数的,大部分的”。 Most students like watching TV.

(2)most作代词常与of连用

构成“most of the+名词”或“most of +代词宾格”,意为“大部分,大多数”。其中of后可接可数名词复数形式,也可接不可数名词,作主语时谓语动词要和of后的名词保持一致。

Most of the apples are red.

Most of us don’t like him, because he is too lazy.

4.be good for…对……有好处,对……有益

be bad for…对……有害处

be good at …擅长,善于做……=do well in

be good to …对……友好(和善,慈爱)=be friendly to =be kind to

5.be/keep in good/poor/bad health身体好/不好

6.have a habit of…有一个……的习惯

7.try to do sth 尽力去做某事,努力做某事

try doing sth 尝试,试着做某事

try one’s best to do sth 尽某人最大努力去做某事

try on 试穿

have a try 试一试,试试(try为名词)

8.look after =take care of 照看,照顾

look after…well=take good care of…照顾的好

9.help sb do (to) do sth=help sb with sth 帮助某人做某事

10.be the same as+n/pron/v-ing 和……一样,与……相同

be different from 与……不同

11.kind of =a bit=a little有点儿,有几分. +形容词和副词,表程度。

12.although=though ,是连词,引导让步状语从句,意为“虽然,尽管”。

在英语里如果用了although 或者though,就不能用but , 但可以用yet 或still.。 although 和though 意思相同,用法也基本一样。但是在让步状语从句中,though的位置比较灵活,although则一般用于句首。另外,在短语even though(即使)和as though(仿佛,似乎)中不能换用 although。

Although he was ill, he (still) worked hard.
