## [转载]倍数的表达

(2012-01-18 11:50:35)

### 转载

在The Merchant of Venice一课中有这样一句话： If you offered me six times what you have just offered, I would still take my pound of flesh.

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 + 其他。

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.

There is five times as much coffee in this glass as in that one.

2. 倍数 + 形容词（或副词）的比较级 + than + 其他。如：

The hall is five times bigger than our classroom.

3. 倍数 + the size / height / length / width. etc. + of + 其他。如：

This road is six times the length of that one.

4. 计量名词 + of + 名词 + be +倍数 + that + of + 其他。如：

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

5. 倍数+what从句。如：

The production is now three times what it was ten years ago.

6. 倍数 + more + 名词 + than +其他。如：

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

7. 其他表达。如：

She’s twice/ double my age.

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

He runs faster than me by three times.

【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twice或double，一倍用once。

【真题再现】

① At a rough estimate, Nigeria is _______ Great Britain.                 （上海卷2005）

A. three times the size as              B. the size three times of

C. three times as the size of           D. three times the size of

② What a table! I’ve never seen such a thing before. It is _______ it is long.（湖北卷2005）

A. half not as wide as                  B. wide not as half as

C. not half as wide as                  D. as wide as not half

③ Americans eat ____ vegetables per person today as they did in 1910.（上海卷2002春）

A. more than twice                      B. as twice as many

C. twice as many as                     D. more than twice as many

【点拨】

①倍数要放在the size of的前面，three times the size of表示“……比……大两倍”，故选D。

②从题意知，这张桌子的长度不到宽度的一半，这里half相当于倍数，放在as前面。故选C。

③more than twice表示数量，应置于as...as结构之前，意为“是……两倍多”。题意：美国人现在每人所吃的蔬菜是1990年的两倍多。选D。
