Writing your opinions about the internet
Teen Life Magazine
Nowadays teenagers spend a lot of time on the internet. What are the positive and negative effects of the internet on their lives Write a paragraph to express your opinions.
1 Look at the lists below and add your own ideas. Support your opinions with examples.
The internet helps us develop our interests
It allows us to stay in touch with friends.
It allows us to learn online.
I love reading science fiction novels, and I post my book reviews online. Every time I write a review, I get hundreds of comments.
Examples
Positive effects
My best friend moved to another city last year, but we still chat every day on WeChat. We share photos of our school life, send voice messages, and even have video calls on weekends.
The internet helps us develop our interests
It allows us to stay in touch with friends.
It allows us to learn online.
During the summer holiday, I wanted to learn how to draw cartoons. I found free video lessons on a learning website. The teacher showed each step clearly, and I could replay the videos when I forgot something. Now I can draw my favorite characters and share them with my classmates online!
Some teenagers spend too much time on social media.
Negative effects
My classmate Tom spends over 3 hours every day on TikTok. He always stays up late to watch short videos, so he often falls asleep in class. Last week, he missed an important math test because he was busy editing a video for his social media account. His parents have to take away his phone to make him study!
Examples
The internet makes teenagers less active in real life.
Many of my classmates prefer playing mobile games at home rather than doing sports. My neighbor Jack used to be on the school basketball team, but now he spends all his free time playing video games online. He has gained weight and often feels tired. His PE teacher even warned him that he might lose his spot on the team if he doesn't start exercising again.
Spending too much time on internet harms our health.
Many students play online games for hours every day ,they often suffer from short-sighted eyes. Sitting in front of the computer or phone for too long makes people less active. It makes you feel back pain and get tired easily. Using the internet late into the night is bad for sleep. This disperses(分散) your energy during class
话题分析
写关于观点类的文章
　本单元我们阅读关于因特网对我们生活影响文章，以对话的形式呈现，要求我们学习“观点”+“事例支撑”这种写作模式，本单元写作要求我们写出因特网对我们生活正面和负面的影响，学会这种写作模式，也要运用本单元的目标言语展开写作。写作时要注意一下几个方面：
一，开篇要明确主题与立场。若有正反观点，可在开头暗示（如
both...and...）；若侧重单方面，直接表明态度。
二，中间：分点论证，结合例子。正面 / 积极影响论证。负面 / 消极影响论证。
观点与例子强关联。避免结构混乱，缺乏层次。一般先写正面观点。再写负
面影响，最后总结。
三，结尾：总结观点或提出建议。
一、开头：明确主题与立场
直接点明主题：用一句话概括讨论的核心话题，可结合现象或问题。
二、中间：分点论证，结合例子

(3)技巧：使用 “for example /take...as an example” 引出例子，用 “also
/moreover” 连接多个观点。
2.负面 / 消极影响论证
结构：问题句 + 实例 + 后果说明。例：
问题：The internet makes teenagers less active.
例子：Classmates prefer games at home, feeling tired.用身边现象说明后果
技巧：用 “however /another problem is that” 转折，增强对比
三、结尾：总结观点或提出建议

So, while the Internet is useful, we should use it wisely.
总结利弊，呼吁合理使用
展望式结尾：结合前文观点，给出未来展望。
例：Yes, it will. We‘ve already started doing some of these things!(课文)
肯定未来可能性，呼应前文例子
注意事项
逻辑连接词

as a result（结果）

I expressed my positive / negative opinions about the internet clearly in my writing.
I supported my opinions with specific examples, such as _________.
I used the words and expressions I learnt in this unit.
I used correct spelling, grammar and punctuation.
The Internet has brought great changes to our life. It has both good and bad effects on teenagers. On the positive side, it helps us develop our interests. For example, I love drawing, and I often watch drawing lessons on the Internet. By following these lessons, I’ve improved a lot and even started my own art blog. Also, the Internet allows us to stay in touch with friends. My best friend moved to another city last year, but we still chat every day on WeChat, sharing funny stories and photos of our daily lives. Moreover, it’s a great tool for learning. During the winter holiday, I used online platforms to study English grammar. The videos and exercises there made learning much easier.
However, there are negative effects too. Many teenagers become less active in real life because of the Internet. They prefer playing mobile games at home instead of playing basketball or running outside. As a result, they often feel tired and weak. Another problem is that some teenagers spend too much time on social media. My neighbor always posts short videos and checks comments every few minutes. He sometimes stays up late doing this, and then he can’t focus in class the next day. So, while the Internet is useful, we should use it wisely.

Advantages and disadvantages of the Internet
The Internet has come into students' life. It brings us not only a lot of convenience and happiness but also troubles．
As a good learning tool, it helps students learn English. They can watch English videos or listen to English songs online. It's also easy to read news and send emails to friends quickly.
But there are troubles too. Some students are addicted to chatting or playing games, which wastes their study time. Staring at the screen for long is bad for their eyes. What's more, watching bad films online can have a bad influence on their growth.
It is clear that the Internet has advantages and disadvantages. I think we should use it correctly.
