倍数表达法是历届高考的热点。当我们要表达甲是乙的几倍时,通常可使用以下句型:

1. 倍数+as+形容词或副词的原级+as+其它。这种结构又常演变成下列两类:

①倍数+as+many+可数名词复数+as;

②倍数+as+much+不可数名词+as。如:

There are seven times as many people as I expected.

是我预料的人数的七倍。

There is five times as much coffee in this glass as in that one.---深圳中小学英语家教哪里好,质量好信誉好?

这个杯子里的咖啡是那个杯子里的五倍。

2. 倍数+形容词(或副词)的比较级+ than+其它。如:

The hall is five times bigger than our classroom.

这个大厅的面积比我们教师大五倍。

3. 计量名词+of+名词+be+倍数+that+of+其它。如:

The size of the newly broadened square is four times that of the previous one.

新扩建的广场为以前的四倍大。

4. 倍数+what从句。如:

The production is now three times what it was ten years ago.---深圳中小学英语家教哪里好,质量好信誉好?

现在的产量是十年前的三倍。

5. 倍数+more+名词+than+其它。如:

There are nine times more books in his bag than in yours.

他书包里的书比你书包里的书多九倍。

6. 其它表达。如:

She's twice/double my age.

她的年龄是我的两倍。

The average income of the staff has been increased by 50 percent compared with last year.

与去年相比,该单位职工的收入已增加了50%。---深圳中小学英语家教哪里好,质量好信誉好?

He runs faster than me by three times.

他跑得比我快三倍。

【考查方向】

1)倍数在句中的位置一般放在第一个as前面或比较级前面或名词前面。

2)用times表示倍数时,一般只限于表示包括基数在内的三倍或三倍以上的数。表示两倍可以用twicedouble,一倍用once.

【重点归纳】

除了我们初中所学的形容词的比较级的用法,本模块我们主要归纳几种句式结

(一)含倍数的比较句型

1. 倍数+as+形容词原级+as…。如:

This bridge is three times as long as that one.

His room is twice as big as mine;in other words,mine is only half as big as his.

【特别提醒】

asas”中间加入名词的句式:

●倍数+as+形容词+a/an+可数名词单数+as

●倍数+as+形容词+可数名词复数/不可数名词+as…。如:---深圳中小学英语家教哪里好,质量好信誉好?

Last year my brother twice as big a new house as mine.

He has collected more than three times as many stamps as I (have).

I spent twice as much time on my studies as you did.

【难点点拨】

该结构的省略:通常省略形容词后面的名词及比较的部分。如:

I have to transfer(转乘)buses so I spend twice as much (money as others)for the bus every day.

2. 倍数+形容词比较级+than…。如:

This street is four times shorter than that one.

Fear of danger is ten thousand times more terrifying than danger itself.

【特别提醒】

倍数+形容词比较级+名词+than…。如:

He earns five times more money now than he did ten years ago.

There are three times more books in our library than in yours.

3. 另外,请注意下面两种说法:

(1) 倍数+what从句。如:

The length of the road is four times what it was three years ago.

(2) 倍数+that of+被比较对象。如:

Airmail charges almost twice or three times that of a normal mail.---深圳中小学英语家教哪里好,质量好信誉好?

(二)其它句式

1. "比较级+and+比较级"表示"越来越…"。如:---深圳中小学英语家教哪里好,质量好信誉好?

Things are getting better and better every day.

Our country is becoming more and more beautiful.

2. "the+比较级…,the+比较级…"表示“越…,就越…”。如:

The more you have, the more you want.

The more a man knows, the less he knows he knows.

【知识扩展】

在形容词比较级前可以加a little, a bit, a lot, no, any, much, far, even,still等副词组表示程度的加深。如:

The result is much better than we expected.---深圳中小学英语家教哪里好,质量好信誉好?


Actually, health is far more important than wealth.
