雅思寫作影響高分的關鍵因素，就是定話從句在寫作中的應用。好多考生經常練習定語從句，卻不知道怎么有效的備考。

定語從句是中國考生在雅思寫作中用得最多的一種從句，也是最純熟的從句，但是為什么寫了大量定語從句的中國考生雅思寫作成績平均分一直保持在5.5分以下呢，到底是從句寫得不恰當使用錯誤，還是因為用得太多而分數不高？本文中，朗閣海外考試研究中心的專家將帶領各位考生分析這其中的原因。

一、用法不當

很多中國考生認為因為which使用次數更少，所以在定語從句中which會比that使用分數更高，這其實是一個誤區(qū)，因為which不能取代that在所有的定語從句中的使用。

A 可共用的地方——指代一般物

例如：

The amount of the rubbish that we produce is increasing at an alarming rate.

在這句話中，that就可以用which取代，而且建議考生當that和which在定語從句中充當賓語的情況下能省略就省略。

再如：

The problem that has been under debate for several decades is that the basic facilities and infrastructure are unlikely to satisfy the needs of more tourists.

B 不能共用的地方——只能用which，不能用that

例如：

Students living in their own homes would live a more comfortable life and have more opportunities to communicate with their parents, which has a beneficial impact on the development of their personal character.

再如：

Television, the most pervasive means of entertainment for the average public, is advancing towards an entirely new era, an era of extraordinary sophistication and versatility, which is likely to reshape the world.

在這兩句話中，which都是不可以用that取代的，因為which在文章中指代的是前面的整句話，所以which后面的謂語動詞用的也是單三形式。當which在從句里面用來表示前面整句話造成的影響時，which前面要用逗號，謂語動詞用單數。

C 只能使用that，不能使用which的地方

1. 當先行詞為all、little、much、few、everything、none等不定代詞時關系代詞用that而不用which。

Many people hold the view that they can do nothing to protect the fragile environment, and everything that does have good impacts on the environment can only be implemented with the political will.

There would be few that could pursue a career without future.

2. 當先行詞既有人又有物時，關系代詞用that，不用which。

There are a great number of ignorant people and large companies that sacrifice the environment to get the maximum profits.

The most important thing is concerned with the reaction of workers and factories that do not agree with this new scheme.

3. 當先行詞有形容詞最高級修飾時，關系代詞用that，而不用which。

Many people have extraordinary willingness to bombard their brains with new experiences, while others avoid the latest things that they think would make them have the feeling of fear.

4. 當先行詞有序數詞修飾時，關系代詞用that，不用which。

The first sight that was caught at the Great Wall has made a lasting impression on him.

The first impression that you leave to the interviewer is the most important thing that determines whether you are admitted by the company.

5. 當先行詞被the only, the very, the same, the right等修飾時，關系代詞用that，不用which。

Travelling exposes the students to a variety of cultures and natural beauty by themselves, the very experience that school education cannot provide to them.

This is the very hotel that we lived last year.

6. 當先行詞被all, every, any, much, little, few, no等修飾時，關系代詞用that，不用which。

Much of the blame that needs to be taken should be placed on tourists themselves, who foolishly clambered all over the revered Buddha statues.

Every child that has auditory deficit would have difficulty in learning to reach the maximum potential.

7. 當主句是以which開頭的特殊問句時，定語從句關系代詞一般用that而不用which.

Which of the books that had pictures was worth reading?

Many people wonder which of the problems that they are facing is the most pressing one and should be researched and solved immediately.

8. 指代人時，只可以使用that以及who，而不可以使用which。

In my opinion, there are plenty of opportunities for everyone in our society, but only those that are adequately prepared and highly qualified can make full use of them.

that不可以用which取代，因為that前面的先行詞是人，所以只能用that或者who來引導。

9. 在強調句型“It is ... that ...”中，只用that，不用which。

It is the lack of financial incentive that is responsible for the shortage of talents in the athletic field.

It is talent that determines whether a person can succeed in any field, particularly in the artistic and mathematic field.

二、缺乏將定語從句轉換成高分的方法

定語從句高分的用法——將定語從句轉換成非謂語動詞，修飾前面的先行詞

1.

例如：Those people who strongly support capital punishment have the following reasons.

改成：Those people strongly supporting capital punishment have the following reasons.

再如：Those students who study in a foreign country seem to be more self-confident, independent and well-informed.

改成：Those students studying in a foreign country seem to be more self-confident, independent and well-informed.

將從句中的關聯(lián)詞who去掉，從句的謂語動詞變成了ing形式

2.

例如：The buildings that were knocked down several years ago are with neither financial nor aesthetic values.

改成The buildings knocked down several years ago are with neither financial nor aesthetic values.

Foods that are exported from a foreign market are more expensive than the local products of the same kind.

改成Foods exported from a foreign market are more expensive than the local products of the same kind.

從句中的that照樣去掉，從句的謂語動詞由被動語態(tài)變成了過去分詞。

3

例如：The forest and bush that have been cleared for agriculture are now suffering from soil erosion.

改成The forest and bush having been cleared for agriculture are now suffering from soil erosion.

從句中的that去掉，構成完成時態(tài)的have變成having，這與主被動沒有關系。

總之，想要在雅思寫作中拿到高分，一定要將定語從句寫對并且要寫好，而定語從句高分的用法就是將定語從句轉換成非謂語動詞，作為后置定語修飾先行詞。
