8AUnit 2 Numbers--语法教案

语法一、基数词

(1)基数词的构成---表示数目多少的词叫基数词。

1.1-12独立成词:one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve。

2.13-19(+teen): thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen。两个音节都要重读。

3.20-90(整十位数+ty): twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety。第一个音节重读。

4.21-99间的两位数,先说“十位”,再说“个位”,中间要加连字符“-”

5.101-999之间的三位数,先说“百位”,再加and,再加末尾两位数。

eg: one hundred and one nine hundred and ninety-nine

156—读作:709—读作:

6.1000以上的大数,使用计数符号,每三位加以逗号,从第一个逗号起单位依次为thousand, million, billion.“万”

表达为ten thousand

【考考你】The road is over___________ metres long.

A. six hundred and fifty-two

B. six hundres and fifty-two

C. six hundred, fifty-two

D. six hundred, fifty and two

二、基数词的用法

1. 从句子成分上分析,基数词在句中可用作主语、宾语、表语等。

Four of them went to the factory. 他们中的四个人去了工厂。(主语)

I want two. 我要两个。(宾语)

My classmate is eighteen. 我的同学十八岁。(表语)

2. 编号的事物用基数词。

Today we are going to study Lesson Five. 今天我们要学习第五课。

He lives in Room 801. 他住在801房间。

3. 表示“年、月、日”时年份用基数词,日期用序数词,其顺序由小到大。

The accident took place in 2006. 这次事故发生在2006年。

4. 钟点表达法

1. 先点后分,顺读法。如:8:53 eight fifty-three

2. 先分后点,倒读法。前半小时用“分钟数+past+已过钟点数”;后半小时用“(60-分钟数)+to+下一个钟点数”;

正好半点用“half past+已过钟点数”;一刻钟用“quarter”。

7:20 twenty past seven; 6:35 twenty-five to seven; 1:58 two to two;

8:30 half past eight; 9:15 a quarter past nine; 9:45 a quarter to ten.

5. 用于加减乘除的数字用基数词。

One plus two is three. 一加二等于三。

Five times six is thirty. 五乘以六等于三十。

6. 表示百分数用基数词。

Thirty percent of them is water. 它们当中有30%的水。

7. 表示分数时,分子用基数词,但分母要用序数词;若分子大于1,分母上的序数词要用复数形式。

Two fifths of the book are mine. 五分之二的书是我的。

8 表示带有小数的词用基数词。小数点前的整数按基数词的规则表示,小数点写作point,小数点后的数字应按数字直接表示出来。

18.38 可写成eighteen point three eight.

9. 数词+名词(+形容词)作定语,名词用单数形式。

A twenty-one-year-old girl is behind me. 一位二十一岁的女孩在我身后。

10. 两组与数词有关的介词短语:

(1) in +定冠词the +数词的复数形式,表示年代。

in the 1870s / 1970s

(2) in +物主代词+数词的复数形式,表示某人的年龄。

in one’s thirties 在某人三十多岁的时候

有时在物主代词后面可加上形容词early 或late 使其含义更确切一些。

The young man is in his early thirties.

注意:“十几岁”要用in one’s teens,不可以说in one’s tens。

11. 数词前加every,表达“每一段时间或每隔一段……”

every ten days every four weeks

每10天/每隔9天每4周/每隔3周

every ninth day every third week

【关于基数词的重点与考点:】

基数词表示顺序编号时:名词+基数词,此时两个词的首字母都要大些。

Class Three Room 5 Lesson One

【考考你】My grandma is in her ____________(八十多岁),but she can still take care of herself.

语法二、序数词

(1)序数词的构成

表示顺序先后的数词叫序数词。序数词大多由基数词变形而成,所以掌握了基数词和基变序的方法,序数词也就简单啦。

基变序的方法:

基变序,有规律,词尾加上th; four-fourth six-sixth

一二三,单独记;八减t,九去e; first, second, third eighth, ninth

ve变f;遇y变ie,词尾再加th。five-fifth twelve-twelfth twenty-twentieth

若遇几十几,只变个位就可以。twenty-two--------- twenty-second

注意:four—fourteen—forty—forty-two nine—nineteen—ninety—ninety-nine

fourth—fourteenth—fortieth—forty-second ninth—nineteenth—ninetieth—ninety-ninth

【考考你】--How was your weekend?

--Great! It was my grandpa’s ______birthday. We enjoyed ourselves.

A. seventy

B. seventieth

序数词的用法

序数词主要用作定语、表语,前面要加定冠词the。

The fifth lesson is very easy to learn. 第五课很好学。

You are the first one I believe. 你是我最相信的人。

【序数词的考点:】

序数词表示顺序时,其前要加the,后面接单数名词。

The second picture is very beautiful.

The fourth student comes from America.

【考考你】Jack got the _______________(four) place in the 100-metre race.

表示日期中的“日”。

如2013年9月19日,表示为“September 19th,2013”; 读作:September the nineteenth, two thousand and thirteen 序数词的缩写:1st2nd3rd4th20th63rd78th

序数词表示编号顺序时:Unit One= the first unit Part Two= the second part

几种特殊数词的表示方法:

普通分数:子饥母叙,分子>1,分母+S (饥-基,叙-序)eg: 1/3: one third 2/3: two thirds

1/2:读作a half或one half

1/4读作a quarter 或one fourth

eg: Two thirds of the earth is covered by water.

百分比:基数词+percent(per cent)

2%读作two percent 27%读作twenty-seven percent

eg: Over 25 percent of the surface of the ground is covered with grass.

习惯表达

one and a half apples= one apple and a half 一个半苹果

half an apple半个苹果one or two apples= one apple or two 一两个苹果

10:30 half past ten

10:25 twenty–five past ten

9:45 fifteen to ten 或a quarter to ten

语法三、加减乘除---数字的运算

加法:3 plus 9 is/equals 12. 减法:9 minus 3 is/equals 6.

乘法:3 multiplied by 9 is/equals27. 除法:9 divided by 3 is/equals 3.

=: is/ equals +: plus -:minus *: multiplied by /: divided by都是表示加减乘除的介词。用于读出已列的算式。eg: --What is 2 plus 3? --2 plus 3 is 5.

而出题者通常用“加减乘除”的动词原形来开头,构成祈使句,命令做题者。

Add A and B Subtract A from B Multiply A by B Divide A by B

If we add 2 to 5, we can get 7. Multiply 2 by 3, please.

Animals United

Animals United is a 3D German(德国的)cartoon which is directed by Reinhard Klooss and Holger Tappe. It is a story about animals that get together to find water. Along their journey, lots of funny things happen, and of course, they have a lot of adventures.

The animals in the grasslands in Africa are waiting for the coming flood(洪水). However, this year's flood seems to come later than in other years. The animals become upset and worried. At the same time, some animals from other places come to the grasslands to look for peace. However, the situation seems worse because the water is becoming less and less. So they decide to look for the river.

Finally, they find the reason why they don't have any water to drink. A dam(拦河坝)has been set up so that humans can have a better life. After a long fight with humans, they let the world know that animals are in danger.

This film is about environmental matters. The humans are the bad and the animals are the good. This film is to give humans a warning that they must not destroy the homes of animals or damage nature in order to improve their own life. Humans should know that animals also have their own world.
