1. 方位介词（Prepositions of place）

1) 常用的方位介词（词组）

成反义词：above---below, over---under, inside---outside, in front of---behind

有关联的：above---over---on, below---under, beside---next to, at---in,

between---among

其他：opposite

2) 使用时的注意点

A. 方位介词在句子中的位置

The book is under the desk. （be动词的后面）

He is standing between the two trees.（实义动词的后面）

Do you know the man in front of the classroom?（放在名词后面修饰它）

He lives in an old house in the center of the city.（作为整句话的状语）

B. above和below，over和under

这两组反义词的前者都表示“在上方”，后者都表示“在下方”。

There are some bridges over the river. What’s under the bed? An old shoe.

The shelf is above the top bunk bed. She lives two floors below Linda.

C. above, over和on

这三个词都表示“在上面”，on是指和物体有接触，over是指在正上方，没有接触面，above也是没有接触面，正上方或斜上方，但现在可代替over，如：

The wooden house is over / above the river. The bag is on the table.

There is a plane flying above our heads.

D. at和in

这两个词常用在arrive后面，at后加小地点，in后加大地点，如：

He arrived at the airport at 4 p.m. We will arrive in Beijing tomorrow morning.

E. between和among

between是指在两者之间，常用词组between…and…，而among是在三者或三者以上之间，如：

I sit between Lily and Lucy.

Mr. Li likes staying among his students.（注：英语中的复数名词，没有特别指出是两个，都默认为三

者或三者以上）

F. opposite：在对面如：Our school is opposite a park.

2. 基数词（Cardinal numbers）

表示数目的数词是基数词。

1) 基数词的构成

A. 两位数：十位数与个位数之间加连字符。如：23 twenty-three

B. 三位数：百位数与最后两位数加and（美语省略and）。

如：201 two hundred and one 642 six hundred and forty-two

C. 四位数：thousand之后加逗号，后面依照以上原则。

如：1,351 one thousand, three hundred and fifty-one

D. 表示万以上的数目，将数字由右向左每三位加一个逗号，使一个数字分成几个小节，称为thousand

节，million节等，然后按节处理，如：

68,343 sixty-eight thousand, three hundred and forty-three

13, 526, 300 thirteen million, five hundred twenty-six thousand, three hundred

▲英语中没有直接的单词来表示“万”和“亿”，如：

一万10,000 ten thousand 两万20,000 twenty thousand

十万100,000 one hundred thousand 三十万300,000 three hundred thousand

一千万10,000,000 ten million 两千万20,000,000 twenty million

一亿100,000,000 one hundred million

▲表示十亿，美国用one billion，英国用one thousand million
