倍數(shù)表達(dá)法是高中英語(yǔ)的高頻考點(diǎn)，也是難點(diǎn)。今天，小編總結(jié)了 高中英語(yǔ)中涉及到的11個(gè)表達(dá)倍數(shù)的句型，尤其是前三個(gè)基本句型，一定要記下來(lái)。

 

 

一. 表達(dá)倍數(shù)的3個(gè)基本句型

 

1.“A+be動(dòng)詞/謂語(yǔ)動(dòng)詞+倍數(shù)+as+形容詞/副詞原級(jí)+as+B”，表示“A正好是B的多少倍”。例如：

 

Asia is four times as large as Europe.

亞洲的面積是歐洲的四倍。

 

This big stone is three times as heavy as that one.

這塊大石頭的重量是那塊的三倍。

 

The plane flew ten times as high as the kite.

那架飛機(jī)的飛行高度是那只風(fēng)箏的十倍。

 

2. “A+be動(dòng)詞/謂語(yǔ)動(dòng)詞+倍數(shù)+形容詞/副詞比較級(jí)+than+B”，表示“A比B大（長(zhǎng)、高、寬等）多少倍”。例如：

 

This rope is twice longer than that one.

這根繩子比那根繩子長(zhǎng)兩倍（是那根繩子三倍長(zhǎng)）。

 

This hall is five times bigger than our classroom.

這個(gè)大廳比我們的教室大五倍(是我們教室的六倍大)。

 

The car runs twice faster than that truck.

這輛小車(chē)的速度比那輛卡車(chē)快兩倍（是那輛卡車(chē)的三倍快）。

 

3. “A+be動(dòng)詞+倍數(shù)+the size/height/length/width, etc+of+B”，表示“A正好是B的多少倍”。例如：

 

This street is four times the length of that one.

這條街是那條街的四倍長(zhǎng)。

 

This hill is four times the height of that small one.

這座山的高度是那座小山的四倍。

 

二. 倍數(shù)表達(dá)基本句型的7種變形

 

除表達(dá)倍數(shù)的三個(gè)基本句型外，我們還要掌握其基本句型的7種變形。

 

1. “ ... times as many/much+名詞+as+被比對(duì)象”。例如：

 

There is four times as much water in this pot as in that one.這個(gè)壺里裝的水是那個(gè)壺里的四倍。

 

There are six times as many students as we expected.學(xué)生數(shù)量是我們預(yù)期的六倍。

 

2. “ ... times+more+名詞（可數(shù)或不可數(shù)）+than+被比對(duì)象”。例如：

 

There are five times more books in our library than in yours.我們圖書(shū)館里的書(shū)比你們圖書(shū)館多五倍多。

 

We have produced twice more grain this year than we did last year.

我們今年生產(chǎn)的糧食是去年的兩倍多。

 

3.“ ... times+over+被比對(duì)象”。例如：

 

The grain output in that village is twice over that of 2002.

那個(gè)村的糧食產(chǎn)量是2002年的兩倍多。

 

4. “ ... times+that+of+被比對(duì)象 ”。例如：

 

In this workshop, the output of July was 4.5 times that of January.

這個(gè)車(chē)間7月份的產(chǎn)量是1月份的4.5倍。

 

5. “...times+compared with+被比對(duì)象”。例如：

 

The number of the students in our school has increased 4 times compared with 1980.

我們學(xué)校的學(xué)生人數(shù)比1980年增加了四倍。

 

6. “...times+what+從句”。例如：

 

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

現(xiàn)在的產(chǎn)量是十年前的三倍。

 

三. 用double表示倍數(shù) 

 

1. double用作形容詞，表示“兩倍的”。例如：

 

The production is now double what it was ten years ago.

現(xiàn)在的產(chǎn)量是十年前的兩倍。

 

2. double用作動(dòng)詞，表示“是……的兩倍。例如：

 

The output has been doubled in the past six years.

在過(guò)去六年中產(chǎn)量已經(jīng)翻了一番。

 

This brought a steady rise in the grain yield. In 2002 it nearly doubled that of 1980.

這使糧食產(chǎn)量不斷增長(zhǎng)。到2002年產(chǎn)量已經(jīng)比1980年將近翻了兩番。
