[高分范文]
Girls and boys，
With the development of the economy， many students have smartphones.①
The students often spend so much time in playing games on them. Some don’t finish their homework on time. Some even sleep in class. Besides， smartphones are bad for eyes， and some students’ eyesight is becoming worse.②
一

To avoid these disadvantages， I think we should make some changes. First， we should keep away from smartphones and work hard. Second， stay with our family or friends if we are free and talk with them about our daily life， feelings and so on. Third， take an active part in all kinds of activities， such as playing basketball， singing songs and playing chess.③
That’s all. Thank you！

Dear Editor，
I’d like to say something about this topic.
With the development of the internet， many students enjoy surfing the internet in their spare time. There are many resources on the internet and it’s convenient for students to find what they need. Some websites provide students with teaching videos. They’re useful and helpful for students’ studies.

But on the other hand， surfing the internet causes a lot of problems. Some students are crazy about playing computer games. The internet takes up nearly all the students’ spare time and they have little time to spend with their parents and friends. They have trouble getting on well with others.
In my opinion， students should use the internet properly. It’s better to regard the internet as a good helper in our studies. Don’t let the internet control our life.

人与社会——科学技术
Facial recognition technology（人脸识别技术） is widely used today. For example， the police use it to search（搜查） for bad guys. Most people use it to unlock phones or doors. It can also be used for payment.
Now， a similar technology， known as facial detection（探测）， is entering a new field： the business of advertising.
一

五
Such systems are going through tests in a small number of stores. There are two kinds of facial detection systems. One facial detection system can judge a person’s “happiness” or “fear” level. That helps businesses see how people feel as they look at advertisements of products in the store. Another system can detect whether someone is wearing glasses or not. If so， stores can send advertisements for new glasses to him.
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people’s ages and five levels of feelings—from “very happy” to “very unhappy”.

Supporters of the technology say it could improve buyers’ experience by showing products they might like or by offering them products at lower prices.
Some are against the idea or using such systems. Pam Dixon， the head of a privacy（隐私） group， is one of them. She thinks the strange actions may cause something unfair. For example， a business could raise the price of a product according to a person’s age and feelings.

② AI and machine learning already play a bigger role in everyday life than you might imagine. Health care， banking， video games， every search on the internet you make ...， all are driven by AI.

⑤ But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots， some people believe AI will make our working lives better. It will improve the work of humans， and new jobs will appear to take the place of the old ones.
⑥ What’s more， machines become more intelligent and they are able to finish more human tasks. Things which only belong to humans like creativity and critical thinking will become even more valuable in the future.

① The smartphone and the computer are two important inventions in our daily life. They help us in many ways， but they may also lead to health problems.
② First， looking at the screen of your smartphone or computer for too long can make your eyes dry. It is not good for your eyesight. To help your eyes keep healthy， you can follow the “20－20－20” rule—after 20 minutes’ use of eyes， look at something 20 feet away for 20 seconds.

③ Next， other parts of our body could also become worse because of using smartphones.When we write a lot of text messages（信息）， we can develop “texting thumbs（拇指）”. It will stop us from holding things well. So we have to exercise our thumbs and fingers from time to time.
④ In addition， smartphones could hurt our brain. One of the biggest problems is that using smartphones can have bad effects on our sleep. Doctors say the screen light keeps us from feeling sleepy. So they advise people not to use smartphones for at least one hour before sleeping.
