Help when parking.

Computers have difficulties making ethical decisions and many people will lose their jobs.

Yes. Because they are convenient. (答案合理即可)

Smartphones are becoming more and more popular in our daily life. They bring many advantages

to us. Smartphones greatly enrich our daily life. First, they let us surf the Internet anywhere at any time.

We can get all kinds of information by watching the news about any country in the world. Second, with

smartphones, we can listen to music, watch films and play games. It is also convenient to do online

shopping. Third, we can keep in touch with each other by chatting on QQ or WeChat. What's more,we can

learn a lot of knowledge by having online courses.

However, every coin has two sides. Using smartphones for too long is harmful to health. Some

teenagers spend too much time on mobile games. As a result, they fail to pass the exams and have poor

eyesight. So using smartphones can affect their study.

In my opinion, whether it is good to use the smartphones depends on ourselves. We should use them

properly to improve ourselves.
