考研英語寫作的題材與我們日常生活息息相關，通常涉及事物間的比較，說明其相似性和相異性、事物之間的因果關系，有時要求考生分析事實，找出原因或解決問題的方法，或對一個問題提出個人看法等，所以，考生在復習時，要盡可能熟悉和掌握表達這些關系的常用句型：

有些作文的出題形式是圖表。因此考生需要熟悉和掌握一些常用的句型來解釋圖表，分析和表達數據間的倍數和比例關系。

Asiaranks first both in area and in population among the seven continents. Europe is second to Asia in population, but in area it is the last but one.

We all hope that a country’s population should be in proportion to its area. Unfortunately, the reality often goes against our will.

And in August as many as car accidents were recorded, indicating an increase of about 79 percent as compared with the number of January.

A is by far the largest university, being over three times as big as B.

“time”常用來表達倍數，總結其搭配，大致有如下幾種：

3 times as large as                           比……大兩倍

3 times the size of       是……3倍大

17 times that of                               是……的17倍

17 times over that of                是……的17倍

17 times greater                              增加了16倍

3 times as against                           為……的3倍

twice/thrice as much as                    是……的2/3倍

在表達倍數時，還可用“倍數+fold”，比如：

Between 1999 and 2002, the industrial output value of our city was up 8-fold.

此外，表達整數倍數的還有：double、more than doubled、treble/triple、quadruple。
