英语中基数词、序数词、分数、小数和百分数的读法
How to say the cardinal numbers, the ordinal numbers, fraction, decimals and percent.
1.基数词的读法：
A. 先说“几十”， 再说“几”，中间用连字符。如：
23— 89—
B. 先说“几百”， 再加and,再加末两位数（或末位数）。如：
twenty-three
eighty-nine
two hundred and twenty-three
four hundred and sixteen
eight hundred and nine
223—
416—
809—
C. 1000以上的数先从后向前数，每三位数加一“,”（千分位）；第一个“,”号前为thousand; 第二个“,”号前为million; 第三个“,”号前为billion。如：
1,001—
4,000—
9,743—
174,301—
750,000,000—
one thousand and one
four thousand
nine thousand, seven hundred and forty-three
a (one) hundred and seventy-four thousand, three hundred and one
seven hundred and fifty million
序数词一般以与之相应的基数词加词尾-th构成，如：tenth（第十），但下面这些基数词在变序数词时， 有特别的地方。如：

It is hard to think of a world without metals. Different metals have different uses, for example, steel is used in cars, and iron is used in electrical equipment. When we use metals, it is important to know how they react with different substance, for example, water and oxygen. The reaction of metals with these substances can be put in order. Here is a table with the metals that react most at the top, and the metals that react least at the bottom.
Read the passage again.Answer these questions.
1.Which of the metals in the table reacts the most with oxygen and water?
2.What happens when you heat calcium in oxygen?
3.Which metals react with steam?
Does iron have a slow or fast reaction with steam?
5.Does copper react with water?
A Simple Scientific Experiment
Below is a description of a simple scientific experiment. It shows us how iron reacts with air and with water.
Aim: To find out if iron rusts (a) in dry air; (b) in water that has no air in it (air-free water); (c) in ordinary water.
Apparatus: 3 clean iron nails; test tubes; test tube holder; cotton wool; oil; Bunsen burner.
Iron in dry air
Method
（1）. Put some iron nails at the bottom of a test tube.
（2）. Push some cotton wool down the tube.
（3）. Leave the tube for one week.
Result： After one week, the nails have not rusted.
Conclusion ：Iron does not rust in dry air.
Iron in air-free water
Method
（1）. Half-fill a test tube with water.
（2）. Boil the water for three minutes. (This makes sure there is no air in the water.)
（3）. Put two or three clean nails in the water.
（4）. Add some oil to the water. This will keep air out of the water.
（5）. Leave the tube for one week.
Result： The nails do not rust in the tube with air-free water.
Conclusion： Iron does not rust in air-free water.
Iron in ordinary water
Method
（1）. Half-fill a test tube with water and add two or three clean nails.
（2）. Leave the tube for one week. Result： The nails rust in the tube with ordinary water.
Conclusion ：Iron rusts in ordinary water.
1.Expend
(1)vi.膨胀，扩张，增长 e g. Water expands when it freeze.
(2) vt. 展开，张开（帆，翅膀）扩大，发展
e g. The old hen expanded her wings to help her children.
Expansion 为expand 的名词形式“扩展，扩张，膨胀”
e g. The suburbs are an expansion of cities.
2.contract
(1) vi. 收缩，缩小 常用with连用
Metals contract is cold weather.
(2) vt.缔结，订约，得病，沾染习惯，使缩小
They ’ve contacted an agreement.
I contracted a cold.
(3) n. 合同契约，enter into/make/sign/have a contract with
与 签订合同
make a contract with 与……签合同
sign a contract签署合同
carry out a contract 履行合同
3．equipment un. 设备
equip v 配备、装备 equip sb with sth 用某物来装备某人====be equipped with
4. react v 对….反应，对…有影响，起作用
react to……. 对…有反应
react on\ upon…… 对…有作用影响
reaction n 反应，影响 reactive adj 有反应的，易反应的
5. conclusion n.结论；断定；结束；结局；协定，协议
come to/arrive at/reach/draw a conclusion得出结论
in conclusion最后
conclude v.结束；断定;订立
conclude with以……而结束
6.astonished adj 人感到吃惊的 astonishing adj 令人吃惊的
astonishment n 惊讶
