最新冀教版七年级英语下册语法精讲全套Unit 1 A Trip to the Silk Road语法精讲一、数词(一) 定义与分类数词是指表示数目多少或顺序先后的词。

表示数目多少的数词叫基数词,如one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词,如first, sixth, tenth, twenty-first 等。

数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。

(二)基数词1.英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(ten thousand),“十万”用“一百个千”表示(one hundred thousand)。

2.用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。

About two thousand people died in the earthquake.大约有两千人在地震中丧生。

Thousands of people go to the seaside every year.每年成千上万的人到海滨去。

3.表示整十的基数词用复数形式可以表示人的大约岁数或年代。

He is in his early twenties.他才二十出头。

This took place in the 1930s.这事发生在20世纪30年代。

(三)序数词1.许多序数词是由相应的基数词后加词尾-th构成的,如four/fourth,six/sixth,ten/tenth,sixteen/sixteenth,但是nine变为序数词是ninth,而不是nineth。

2.twentieth, thirtieth, fortieth等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th构成。

3.first, second, third通常可缩写为1st, 2nd, 3rd。

凡是以th结尾的序数词可缩写为“基数词+th”:4th, 5th, 9th, 11th, 60th, 128th等。

4.非整十的多位数,将个位数变成序数词即可:twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),three hundred and sixty-fifth(第365)等。

5.hundred, thousand, million等序数词形式为hundredth, thousandth, millionth 等。

6.序数词前通常要用定冠词,但表示考试或比赛等的名次时,通常可省略其前的定冠词。

He was (the) third in the exam.他考试得了第三名。

【注意】(1)有时序数词前不用定冠词,而用不定冠词,表示次第在原有基础上的增加。

We’ll have to do it a second time.我们得再做一次。

(2)序数词前用定冠词和不定冠词的区别在于:定冠词表特指,不定冠词表泛指,有类似another的意思,但比another 的意思更明确。

二、一般将来时(一)(一)概念一般将来时表示将来某一时刻的动作或状态,或将来要发生的事情。

(二)构成主语+will+动词原形(三)用法一般将来时常与一些表示将来的时间状语连用,如:tomorrow(明天), next week(下周), from now on(从现在开始);in the future(将来);someday (未来的某一天) 等。

(四)一般将来时的句子结构1.肯定句:My father will go to Shanghai next week.我父亲下周要去上海。

We shall go to school tomorrow.明天我们将要去上学。

2.否定句:My father won’t go to Shanghai next week. 我父亲下周将不会去上海。

We shall not go to school tomorrow.我们明天将不去上学。

3.一般疑问句:Will your father go to Shanghai next week? 你爸爸下周将要去上海吗?肯定回答:Yes, he will.是的,他将要去。

否定回答:No, he won’t.不,他将不去。

Shall we go to school tomorrow?我们明天将要去上学吗?肯定回答:Yes, we shall.是的,我们将会。

否定回答:No, we shall not.不,我们将不会。

4.特殊疑问句:—When will your father go to Shanghai?你爸爸什么时候将要去上海?—Next week.下周。

—When shall we go to school?我们什么时候去上学?—Tomorrow.明天。

【注意】will 用于各种人称, shall 只用于第一人称I,we。

Unit 2It’s Show Time!语法精讲一般过去时(一) 定义一般过去时表示过去经常进行的动作或所处的状态,多与时间状语yesterday, last…,…ago, just now, the other day, once upon a time, when she was young等连用。

(二)句式结构肯定句式: 主语+过去式.否定句式: 主语+助动词didn’t+动词原形.疑问句式: 助动词Did+主语+动词原形?(三)一般过去时的用法1.表示过去某一时刻或某段时间发生的事,多与时间点或时间段连用。

I studied in this school ten years ago.十年前我在这所学校学习。

I got up at six this morning.今天早晨我六点起床的。

2.表示过去连续发生的动作,往往没有时间状语,而是通过上下文来表明过去的含义。

She opened the window, looked out and found some birds in the sky.她打开窗户、向外看了看, 看到空中有一些鸟。

3.某些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态,也应该使用过去时。

I didn’t know you were here.我不知道你在这里。

We thought you were ill.我们以为你病了。

(四)动词过去式的变化动词的过去式有规则变化和不规则变化两种形式,一般是在词尾加-ed构成。

不规则变化的过去式没有特定的规律,需要特别记忆。

1.规则变化的过去式(1)一般情况下,在动词的词尾加ed构成。

walk—walked, offer—offered, join—joined(2)以不发音字母e结尾的,直接加d构成。

live—lived, hate—hated, escape— escaped(3)以重读闭音节结尾,并且词尾只有一个辅音字母的,要先双写这一字母再加ed。

stop —stopped,prefer—preferred(4)以“元音字母+ y”结尾的直接加ed,以“辅音字母+ y”结尾的应先将y改为i再加ed构成。

play—played, copy—copied,try—tried,carry—carried2.不规则变化的过去式(1)原形和过去式相同。

花费cost cost切割cut cut(2)字母o改为a。

成为become became来come came(3)过去式为ought结尾的。

带来bring brought买buy bought战斗fight fought想think thought(4)过去式为aught结尾的。

抓住catch caught教teach taught(5)将eep改为ept。

保持keep kept打扫sweep swept(6)字母i改为a。

下沉sink sank游泳swim swam(7)字母ow改为ew。

知道know knew投掷throw threwUnit 3School Life语法精讲频度副词(一) 定义在某一时间段内表示动作发生频率的副词就是频度副词。

usually, sometimes, always, often等词被称为频度副词,是用来表示动作频率的,但程度上有别。

常见频度副词按频率大小排列如下:always>usually>often>sometimes>seldom> never(二)频度副词的位置频度副词在句中习惯上位于be动词、助动词之后,行为动词之前。

1.在be动词之后。

She is sometimes very busy.她有时很忙。

2.在第一个助动词或情态动词之后。

I will never forget this lesson.我将永远忘不了这一课。

3.在实义动词之前。
