托福独立写作是需要30分钟时间完成的300字以上的作文，也就是给出一个话题或者一个论述，然后考生需要用一篇文章来表达自己针对这个话题的观点。很多同学看到这样的任务都会觉得非常难，但是独立写作都是有“套路”的，现在就让我们一起来看看独立写作应该如何写好开头段。
开头段又叫introduction段，它的作用是引入话题，并且综合概述全文观点，所以它的组成有两部分：
• General statements (to give background information)
• Thesis (to show the main theme in the essay)
意思就是一开始需要用一两句话来给出背景信息，来说明这篇文章主要谈论的是什么，然后再用一句话写明这篇文章的主题，也就是亮明自己的观点。
我们来看一个例题：
• Do you agree or disagree with the following statement? The invention of the Internet has had negative effects on your civilization. Use specific reasons and examples to support your opinion.
题目翻译：你同意或者不同意以下观点？网络的发明对于文明有消极影响。用具体的原因和例子来支持你的观点。
首先确定观点，这里假如我们采取支持的观点。然后写出全文的主题句，也就是头一段的结尾一句，写这句话的要点是把你的观点具体化：
The Internet enables us to communicate more easily, save time, and save money.（网络能够使我们交流更容易，节约时间，节约金钱）
接着写前面的主题引入部分，也就是在你要谈论的主题上进行适当拓展，介绍它的大环境，和人们对于它的一些普遍观点：
People have always been worried about the impact when new technology is introduced. For instance, business people are worried about profits since a new technology can make their company obsolete. Yet, progress itself is not negative. The positive or negative impact of technology results from how it is used. One recent development in technology, the Internet, has both positive and negative potential. However, overall, I feel that the Internet is positive for society since it enables us to communicate more easily, save time, and save money.
这就是一个完成度很高的介绍段。
接下来我们看一些介绍段的句型：
Some people say that it is most important to protect the environment against pollution.一些人说……
Others say that it is more important to create jobs, even if pollution is a result.另一些人说……
I agree/disagree with the view that …我同意/不同意xx观点……
There are several/ a number of reasons that 我同意/不同意的原因是……
There is no doubt in my mind that/There is no question that… 对于……的观点我确信无疑
好了，让我们来做一些练习，请写出下列题目的开头段：
• Do you agree or disagree with the following statement? Classmates are a more important influence than parents are on a child’s success in school. Use specific reasons and examples to support your answer.
• Some people say that computers have made life easier and more convenient. Other people say that computers have made life more complex and stressful. What is your opinion? Use specific reasons and examples to support your answer.
• It is better for children to grow up in the countryside than in a big city. Do you agree or disagree? Use specific reasons and examples to develop your essay.
