写作题型
上周，ETS外网放出了新版托福写作题型--学术讨论的最新10套模拟题，也上线了AI打分系统。我迫不及待地选择了一套题进行了写作&打分测试，一起来看看吧~
首先，我们来看一下题目：
Question3：Your professor is teaching a class on environmental science. Write a post responding to the professor’s question.
In your response, you should:
• l express and support your opinion
• l make a contribution to the discussion
An effective response will contain at least 100 words. You will have 10 minutes to write it.
Doctor Diaz
Nowadays, the world is facing a number of pressing environmental problems, and over the next few weeks, we'll be discussing various innovations that may help solve these problems. To begin our discussion, I'd like you to think of one global environmental problem-for example, it could be related to water, air, land, climate, biodiversity, energy, or something similar. Then explain what you think would be an effective solution to this problem.
Kelly
One of the major environmental problems is the limited freshwater supply in many areas of the world, which means that we need to find effective technologies to provide people with enough drinking water. One solution is to improve the technology for removing salt from seawater, which could allow us to use seawater to replenish dwindling freshwater supplies.
Paul
I think the biggest problem is the air pollution caused by the overuse of motorized vehicles. The obvious solution is for local governments to promote alternatives, like building bike lanes in cities or improving public transportation with electric buses. Both of these would be easy to implement as well.
要注意新版学术讨论的写作内容要求是：
1）回答教授的问题；
2）内容不能与以上两位同学的回答相同，要对discussion有所贡献。所以针对该题，我们需要写的是一个环境问题+解决它的有效方式。而Kelly同学提到的淡水资源短缺及Paul同学提到的空气污染问题，我们需要排除，好写其他的环境问题。

范文示例
以下是老师写的范文，AI给出了5分（满分）的成绩：
鉴于官方之前给出的满分范文长达170词+，所以本文在写的时候词数也偏长，达到了191词，导致写作时间确实比较紧张。但其实在剩余的几套题中，我也有尝试写150-160词，也是可以拿到满分的成绩的哦。所以，各位同学不需要在词数上特别焦虑，目前比较建议的词数是在120-180词之间。
整体的写作结构大家可以参考上图，按照背景1句 → 自己观点1句 → 论证6-8句的结构来完成，当然不同的立场和题型在结构上还会有些许的变化，但是大体的框架变动不大。
在论证方面，我们依然可以采用说理论证或是举例论证的方式来写，在论证过程中适当添加细节来支撑自己的观点。之前学过独立写作主体段写作技巧的同学们对此应该很熟悉，还没有了解过的同学，欢迎来新航道找我们学习哦~

亮点词汇与句型
最后，在语言方面，我们也需要保持词汇使用的地道、句型的多变及语法的正确。以下是上文中的亮点词汇与句型，供大家参考：
1) exacerbate v. 使...恶化
2) a series of 一系列的
3) pressing adj. 迫切的；紧急的
4) soil contamination 土壤污染
5) the indiscriminate use of ... 某物的滥用
6) put ... high on the agenda 某事是当务之急
7) It is a consensus that ... 某事是一个共识
