条件状语从句在雅思写作中的应用

大作文举例只会用if？是时候换换啦

——条件状语从句在写作中的应用

王洪亮

今天跟大家分享一个老生常谈的知识点，什么叫做条件状语从句呢？通俗来讲，往往由引导词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后，其它事情才能发生，通常译作“假如”。在写作中，条件状语从句十分好用，拿过来就能用，可以起到很好的突出强调作用。

一提到条件句，很多同学马上就会想用if来引导。首先，我们一起来看以下七个句子：Part A：

1 You can borrow my dictionary if you return it before you go home.

2 You cannot go to university if you do not have good grades.

3 Pollution will get worse if we continue to live in a throwaway society.

4 Many developed countries are willing to waive the Third World debt if the mon-ey is reinvested in education and medicine.

5 Some countries will never be able to rectify their deficits even if they work hard.

6 Computers are difficult things to understand, even if you read a lot of books about them.

7 Crime is a problem, even if you go to relatively safe countries.

这些句子都是由if 引导的条件句（ even if 可以是条件也可以是让步状语从句），这些句子固然很好，但是是不是有些千篇一律呢？条件状语从句不仅仅限于if，下面给大家介绍一些可以替换if 的方式。我们分别用以下短语来替换上面七句话中的if ：

providing that （假如） / unless (除非） / as long as （只要） / on condition that （如果，条件是）/ no matter how （不管怎样）/ however many （无论多少）/ wherever （无论什么地方）

第一句话可以直接用providing that ( 也可以用provided that ) 来替换if

1 You can borrow my dictionary providing that you return it before you go home. 第二句话可以把if not 换成unless

2 You cannot go to university unless you have good grades.

第三句话可以直接用as long as 替换if

3 Pollution will get worse as long as we continue to live in a throwaway society.

第四句话可以直接用on condition that 替换if

4 Many developed countries are willing to waive the Third World debt on condi-tion that the money is reinvested in education and medicine.

第五句话用no matter how 直接替代if

5 Some countries will never be able to rectify their deficits even if they work hard.

第六句话用however many 直接替代even if

6 Computers are difficult things to understand, however many books you read about them.

第七句话用wherever 直接替代even if及后面的内容，改写为

7 Crime is a problem, wherever you go.

Part B: 如果我们强调的重点是条件里的内容，那么我们可以把条件句放在句子的前面。我们现在试着把刚刚七个句子的强调内容提前。

1 Providing that you return it before you go home, you can borrow my dictionary.

2 Unless you have good grades, you cannot go to university.

3 As long as we continue to live in a throwaway society, pollution will get worse.

4 On condition that the money is reinvested in education and medicine, many de-veloped countries are willing to waive the Third World debt.

5 No matter how hard they work, some countries will never be able to rectify their deficits.

6 However many books you read about them, computers are difficult things to understand.

7 Wherever you go, crime is a problem.

Part C: 练习

现在到大家自由发挥的时间了。大家根据上面七个短语，来试着补充以下句子

2 Working for a large company can be a fulfilling experience ____

3 Most banks are happy to lend customers money _____________

Part D: 此外，一些名词也可以表示条件，比如
