The Internet's Effects on Teenagers
The internet has both positive and negative effects on teenagers' lives.
On the positive side, it helps us developing our interests. For example, I love read science fiction novels, and I post my book reviews online. Every time I write a review, I get hundreds of comment. Also, it allows us to learn online. Last month, I took an online coding course and learned a lot of useful skills.
However, there are negative effects too. Some teenagers spend too much time in social media. My cousin, for instance, spends more than five hours a day scrolling through social media apps, which makes him have little time for homework. What's more, the internet may expose us to inappropriate content. Once, my little sister saw a scary video by accident when she was using the internet, and she was afraid to sleep alone that night. In conclusion, while the internet is helpful, we should use it properly.

Writing Suggestion
Sentence Structure:
Adopt a "general statement - positive effects - negative effects - conclusion" structure.
Start with an overview of the Internet's dual impact, then detail positives and negatives with examples, and end with a call for proper use.

Writing Suggestion
Use vivid and precise language. Employ a mix of simple and compound sentences. For example, "The internet opens up a world of knowledge, yet it also brings some troubles."

Writing Suggestion
Before Writing
Brainstorming: Recall personal internet usage experiences. Think about how it helps with study, socializing, or hobbies, and also any downsides like excessive screen time or online distractions.
Listing Ideas: Complete the "Positive effects", "Negative effects" and "Examples" tables. Add more points such as the internet aiding in creative projects or causing sleep disorders due to late - night use.
Outlining: Sketch a rough outline with the main points (e.g., two positive and two negative effects) and their supporting examples to ensure logical flow.

Writing Suggestion
While Writing
Maintain Coherence: Use transition words (e.g., moreover, on the contrary, for example) to link sentences and paragraphs. This makes the writing easy to follow.
Elaborate Examples: When giving an example, explain how it illustrates the effect. If you write "It helps develop interests", add "Like my friend who learned guitar through online tutorials and now performs in a band."
Check Clarity: Regularly read aloud what you’ve written to ensure your opinions and examples are clear and easy to understand. Revise ambiguous sentences promptly.
adj.模棱两可的
adv.立即；马上

After Writing
Self - Checking: Use the provided checklist to verify if you’ve clearly expressed opinions, supported them with examples, used unit vocabulary, and ensured correct spelling, grammar, and punctuation.
Peer Review: Exchange writing with a classmate. Ask them to give feedback on clarity, example relevance, and overall flow.
Revising: Based on self - check and peer feedback, make necessary changes. Improve weak examples, fix grammatical errors, and enhance sentence variety.
