想要提高托福写作分数？快来学习这六种复合句吧！

　　我们注意到托福官方评分标准中语法部分强调两点∶展示syntactic variety(句法的多样性)和errors(错误)越少越好。

　　当然，提升语法的正确性是考生的首要任务。但要取得高分，就一定要展示语法多样性。

　　于是很多学生就会理解成，要多写复合句(从句)，似乎越多越好，越长越好。

　　其实不然，考官要看的，是考生能不能恰当、地道地运用不同的从句。

　　什么是复合句?

　　从结构上说，句子分为三类∶

　　1.简单句 (Simple Sentences)——句子成分都由单词或短语担任，且只有一个主谓结构。

　　例∶ I love you.

　　2.并列句(Compound Sentences)——句子成分都由单词或短语担任，但有两个或更多的互不依从的主谓结构。

　　例∶ I lover you, and you love me.

　　3.复合句 (Complex Sentences)———从句担任句子成分。

　　例：I believe that you love me.(从句担任该句宾语)

　　中国考生熟悉的从句是宾语从句(I think that…)、状语从句(If/because…)和定语从句(… people who..)。

　　不熟悉的从句是主语从句、表语从句和同位语从句。

　　接下来，大家和南京托福培训机构小编一起重点学习这六种从句在写作中最常用的句式。

　　快速学习六种复合句

　　宾语从句

　　下面例句中∶第 一句大家都会写;第二句包含两个从句;第三句是介词后的宾语从句，会写的考生不多，要重点学习。

　　· Many people believe that we have developed into a"throw-away society".

　　· While there are both benefits and drawbacks to a multicultural society,it is safe to say that the prosoutweigh the cons.(while 引导状语从句，that 引导宾语从句)

　　· Traditionally, the approach has been to punish criminals by placing them in prisons to pay for what they have done.(what 引导宾语从句，作为介词 for 的宾语)

　　状语从句

　　状语从句花样很多，除了人人都会的 because 以外，还要求大家复习两种∶if引导的条件状语从句和 while (虽然、尽管)引导的让步状语从句。

　　1. If

　　· If a student wants to learn aboutjob-specific information,they don't need to sit in a classroom to get it.(有时可用when,once代替)

　　· If a person loses a job but can get assistance,or a minority still has an equal opportunity of success, then we can say this country is advanced.

　　· Many medications and procedures currently in use would not exist if animal testing was banned.(当表示可能性很小或想象中的事情时，用虚拟语气)

　　2. While

　　· While people traditionally prioritize caring,sharing and generosity in life and work,modern people seem to be more self-absorbing and self-concerned.

　　· While the economic development has made our life more comfortable, it has also polarized the society in the distribution of wealth.

　　· Whie traditional buildings might look nice from the outside，they are often not very user-friendly.(有时可用 although 代替)

　　定语从句

　　复习三种就行。

　　1. who 引导，修饰"人"Those who…，……的人……Students who…，……的学生……Children who…，……的孩子…….

　　· Those who feel that sports stars' salaries are justified might argue that the number of professionals with real talent are very few.

　　· Students without teachers will surely be lost; but students who simply rely on teachers for knowledge aren't really learning.

　　· Chidren who enter school at an early age are generlly more confident and independen than children who stay at home with their parents.

　　2. that 引导，修饰"物"

　　· Likewise,economics is a findamental discpline that allows societies to be stable and move forwar.

　　· The workload that could take months to finish by manual labor could be done flawlessly by robots in minutes.

　　· How to handle criminals is a problem(that)all countries and societies face.(that 在定语从句中作宾语，可省)

　　· Advertisement is an effective marketing tool(that)almost every company uses.(同上)

　　3. 逗号后加 which 引导，修饰前面的整个句子 (非限制性定语从句)

　　· If fuel prices go up,either fewer people will drive or people will drive less,which makes sense for reducing pollution.

　　· Demand for various commodities creates a huge market for the local and international businesses,which in turn increases demand for the labor market.

　　· Governments should develop and launch a good traffic control system, which can monitor and facilitate traffic flows on major roads for better and safer road usage,reducing the chances of acidents.

　　主语从句

　　用that或wh-词引导的从句作为主句的主语名词。

　　在写作中我们只需要会写下面3个主语从句∶(下划线部分为句子主语)

　　1. Whether 引导的主语从句

　　· Whether mobile phones bring more harm than good to us has caused heated debate.

　　· Whether the increase of fuel price can solve the world's environmental problem is a controversial issue.

　　· Whether universities should provide students with practical skills or academic knowledge is a controversial issue.

　　2. 先行词 it 开始的主语从句

　　· It is obvious that we are living in an information age.(该句是 That we are living in an information age is obvious. 的变形。)

　　· It is obvious that investing in education is investing in one's future.

　　· It is obvious that human activities have the greatest impact on environment.

　　3. 在文章中辩论时，要强调自己观点的正确性并同时驳斥反方观点，我们有一种强大的句型武器∶what 引导的主语从句 + not… but…. 搭配。

　　· What governments should do is to create policies to encourage low carbon development.

　　· What most companies and workforces need are not robots, but creative people who can contribute ideas.

　　· What the poor countries need most is not money,but advanced technologies and talents in some key areas.

　　同位语从句

　　同位语从句实际上是 that 前面那个名词的解释或具体内容。that在这里相当于破折号(——)的作用。

　　· Nowadays,an increasing number of people are concerned about the phenomenon that our kids are spending more time watching TV.(第 一段第 一句用到)

　　· I agree with the view that not only governments but every single citizen should do one's part to fix this problem.(第 一段最后一句用到)

　　· The fact that we have different languages demonstrates that we have different cultures.

　　表语从句

　　背诵下面三个句子中加粗的黑体部分就行。

　　· This means that change is not always a personal option, but an inescapable fact of life.

　　· This is because it is the rich and powerful people in our society who are able to impose changes.

　　· Another reason for this is that old buildings, like native language,form a cultural identity and keep a unique record of a country.

　　融会贯通以上南京托福培训机构小编分享的的从句，你就拥有了托福写作25分以上的语法功力。

　　再在作文中点缀一些花俏招式，比如not only…but also…;neither…nor…;too…to…;not to mention;regardless of 等，你的作文一定会很精彩!
