提出不同观点

阐述不同人的不同看法。

使用连接词如“Some people think… the others…”，“On the one hand… on the other hand…”等来组织内容。

例如：“Some people think that… whereas others argue that…”

个人观点

表达你自己的看法，通常以“I think”或“As far as I am concerned”开头。

给出支持你观点的理由或例子。

例如：“I firmly believe that…”或“For one thing,… For another…”

论证

详细阐述你的观点，可以使用事实、数据或例子来支持。

保持逻辑清晰，条理分明。

例如：“Taking all these factors into consideration, we may safely come to the conclusion that…”

检查语法和拼写

确保句子通顺，语法正确，拼写准确。

使用适当的标点符号，如逗号、句号等。

字数控制

根据题目要求控制字数，通常不少于80词。

话题：The Impact of Social Media

作文：

Nowadays, there is a growing concern over the impact of social media on young people. Some people think that social media has a positive influence, as it provides a platform for people to connect and share their ideas. Others argue that it has a negative impact, as it can lead to addiction and affect mental health.

As far as I am concerned, I agree with the opinion that social media has both positive and negative effects. For one thing, it helps people stay in touch with friends and family, especially those who live far away. For another, it can be a powerful tool for learning and networking. However, we should also be aware of its potential negative effects, such as cyberbullying and the pressure to present a perfect life.

In conclusion, social media is a double-edged sword that we should use wisely. By being mindful of its impact, we can harness its benefits while minimizing its drawbacks.
