雅思复杂句写法：定语从句、状语从句、名词性从句怎么用才自然

很多同学一听到“雅思写作要用复杂句”，第一反应就是：

那我是不是要写很长、很绕、很高级的句子？

不一定。

雅思写作里的复杂句，不是越长越好，也不是从句越多越好。真正有用的复杂句，应该做到三件事：

• 语法准确
• 逻辑清楚
• 服务内容

如果一句话为了“复杂”写到主谓不一致、从句接错、意思模糊，那不但不加分，反而会扣分。

这篇文章重点讲雅思写作里最常用、最值得掌握的三类复杂句：

• 定语从句
• 状语从句
• 名词性从句

你不需要把语法书从头背一遍。备考雅思时，先把这些高频结构用稳，就足够明显提升句式多样性。

一、雅思复杂句到底有什么用

雅思写作评分里有一项叫 grammatical range and accuracy，也就是语法范围和准确性。

这里有两个关键词：

• range：你能不能使用不同句型
• accuracy：你用得对不对

所以复杂句的目标不是炫技，而是让文章更清楚地表达复杂关系。

比如：

简单句：

Many children use smartphones. Their parents are worried.

更自然的复杂句：

Many parents are worried because their children spend too much time using smartphones.

再比如：

简单句：

Online learning is flexible. It is popular among working adults.

复杂句：

Online learning, which offers greater flexibility, is popular among working adults.

复杂句真正解决的是“关系表达”：

• 谁修饰谁
• 为什么
• 虽然怎样但怎样
• 如果怎样会怎样
• 什么事情很重要
• 某个观点是否成立

二、复杂句写作的基本原则

1. 先准确，再复杂

不要为了复杂而硬写。

低质量复杂句：

People who they live in cities which have many cars are suffer from pollution.

问题很多：

• who they 重复主语
• are suffer 动词错误
• 句子结构混乱

更好写法：

People who live in large cities often suffer from air pollution caused by heavy traffic.

2. 一句话只表达一个主逻辑

很多考生喜欢把所有内容塞进一句话：

Although technology is useful because it helps people work faster which is important for companies that want to compete in the market, it also has problems.

这句话太拥挤。

更好写法：

Although technology helps people work more efficiently, it can also create problems. For example, employees may feel pressure to stay connected after work.

3. 复杂句要和段落逻辑配合

复杂句不是孤立存在的。它应该放在合适位置：

• 主题句：可以用名词性从句表达观点
• 解释句：可以用原因状语从句
• 例子句：可以用定语从句补充信息
• 让步句：可以用 although / while

三、定语从句怎么用

定语从句的作用是修饰名词，相当于中文里的“……的”。

基础结构：

名词 + who / which / that / where / when + 从句

1. who 修饰人

who 用来修饰人。

例句：

Students who study abroad often become more independent.

People who work long hours may have less time for exercise.

Children who receive enough support from their parents are more likely to perform well at school.

写作替换：

简单句：

Many students study abroad. They become independent.

合并：

Many students who study abroad become more independent.

2. which 修饰物或一件事

which 可以修饰物，也可以修饰前面整件事。

修饰物：

Online learning, which is flexible and convenient, has become increasingly popular.

修饰前面整件事：

Many people now work from home, which reduces the time they spend commuting.

注意：

第二种 which 指的是“很多人现在在家工作”这件事，不是单个名词。

常用句型：

• ..., which can lead to...
• ..., which may result in...
• ..., which means that...
• ..., which makes it easier for people to...
• ..., which is one reason why...

例句：

Many young people rely heavily on social media, which may reduce face-to-face communication.

Governments can invest more in public transport, which would help reduce traffic congestion.

3. that 修饰人或物

that 可以修饰人或物，语气比 which 更紧密。

例句：

The skills that students learn at university may affect their future careers.

The policies that governments introduce should protect vulnerable groups.

注意：

正式写作里，人通常优先用 who，物可以用 which 或 that。

4. where 修饰地点

where 用来修饰地点。

例句：

Cities where public transport is reliable usually have less traffic congestion.

Schools where students receive individual support tend to produce better academic results.

常见写作场景：

• cities where...
• countries where...
• schools where...
• workplaces where...
• communities where...

5. when 修饰时间

when 修饰时间。

例句：

There are times when children need guidance from adults.

In an age when technology develops rapidly, lifelong learning has become essential.

雅思写作里，when 不如 who / which / where 高频，但可以自然使用。

6. 非限制性定语从句

非限制性定语从句用逗号隔开，用来补充说明。

结构：

名词, which/who..., 谓语...

例句：

Public transport, which is cheaper and more environmentally friendly than private cars, should receive more government funding.

University graduates, who often have stronger professional skills, may find it easier to obtain well-paid jobs.

注意：

非限制性定语从句一般不用 that。

错误：

Public transport, that is cheaper, should be improved.

正确：

Public transport, which is cheaper, should be improved.

四、定语从句常见错误

1. who 和 which 用错

错误：

Students which study hard can get better results.

正确：

Students who study hard can get better results.

2. 从句里重复主语

错误：

People who they live in cities face more pressure.

正确：

People who live in cities face more pressure.

3. 缺少谓语

错误：

Children who from low-income families need more support.

正确：

Children who come from low-income families need more support.

或者：

Children from low-income families need more support.

4. 句子太长

不要一个定语从句接一个定语从句。

不推荐：

Students who study in schools that are located in cities which have many educational resources are more likely to succeed.

更好：

Students in urban schools often have access to more educational resources. As a result, they may have better academic opportunities.

主语从句可以把一件事放在句首当主语。

可以直接做这种改写训练：

简单句：

改写：

Many people who live in cities face high living costs.

简单句：

Public transport is cheap. It can reduce traffic congestion.

改写：

Public transport, which is relatively cheap, can help reduce traffic congestion.

简单句：

改写：

Because children often use smartphones excessively, their parents should set reasonable limits.

备考时，你可以在 优秀雅思 里练写作，然后用这篇文章检查自己的句子：有没有定语从句、有没有原因或让步从句、有没有 It is clear that... 这类名词性从句，以及最重要的，从句有没有写对。 官网：<https://ielts.youshowedu.com> 如果你用 iPhone 或 iPad，也可以直接去苹果应用商店搜 优秀雅思。

最后记住：

雅思复杂句不是为了把句子写长，而是为了把关系写清楚。

你能稳定写出准确的定语从句、状语从句和名词性从句，语法多样性就已经比只会简单句的作文强很多。
