定语从句是使用频率非常高的一种句型，掌握起来相对容易。但是，在实际写作的过程中，同学们在这个部分还是会犯一些基本的语法错误，影响到最后的分数。下面小编为大家分享定语从句作文例句，欢迎大家参考借鉴。
一、用法不当
很多中国考生认为因为which使用次数更少，所以在定语从句中which会比that使用分数更高，这其实是一个误区，因为which不能取代that在所有的定语从句中的使用。
A.可共用的地方——指代一般物
例如：
The amount of the rubbih that we produce i increaing at an alarming rate.
在这句话中，that就可以用which取代，而且建议考生当that和which在定语从句中充当宾语的情况下能省略就省略。
再如：
The problem thatha been under debate for everal decade i that the baic facilitie andinfratructure are unlikely to atify the need of more tourit.
B.不能共用的地方——只能用which，不能用that
例如：
Student living in their own home would live a morecomfortable life and have more opportunitie to communicate with their parent,which ha a beneficial impact on thedevelopment of their peronal character.
再如：
Televiion, the mot pervaive mean of entertainmentfor the average public, i advancing toward an entirely new era, an era ofextraordinary ophitication and veratility, which i likely to rehape the world.[由wWw.HaozuoWen.com整理]
在这两句话中，which都是不可以用that取代的，因为which在文章中指代的是前面的整句话，所以which后面的谓语动词用的也是单三形式。当which在从句里面用来表示前面整句话造成的影响时，which前面要用逗号，谓语动词用单数。
C.只能使用that，不能使用which的地方
1. 当先行词为all、little、much、few、everything、none等不定代词时关系代词用that而不用which。
Many people hold the view that they can do nothing to protect thefragile environment, and everything thatdoe have good impact on the environment can only be implemented with thepolitical will.

2. 当先行词既有人又有物时，关系代词用that，不用which。

二、缺乏将定语从句转换成高分的方法
定语从句高分的用法——将定语从句转换成非谓语动词，修饰前面的先行词
例如：Thoe people who h2ly upport capital punihment havethe following reaon.
改成：Thoe people h2ly upporting capital punihmenthave the following reaon.
再如：Thoe tudent who tudy in a foreign country eem tobe more elf-confident, independent and well-informed.
改成：Thoe tudent tudying in a foreign country eem tobe more elf-confident, independent and well-informed.
将从句中的关联词who去掉，从句的谓语动词变成了ing形式
例如：The building that were knocked down everal year ago arewith neither financial nor aethetic value.
改成The building knocked down everal year ago arewith neither financial nor aethetic value.
Food that areexported from a foreign market are more expenive than the local productof the ame kind.
改成Food exported from a foreign market are more expenive than the localproduct of the ame kind.
从句中的that照样去掉，从句的谓语动词由被动语态变成了过去分词。
例如：The foret and buh that have been cleared for agricultureare now uffering from oil eroion.
改成The foret and buh having been cleared for agricultureare now uffering from oil eroion.
从句中的that去掉，构成完成时态的have变成having，这与主被动没有关系。
