【预测题目1】
Nowadays，mobile phones are very popular. They are playing an important role in our life. We can use them to read news，send messages，make phone calls and read all kinds of books. Besides，we can use them to enjoy music，do some shopping and play games. In a word，mobile phones have made our life more colorful.
However，they also bring us many problems. For example，if people use them while riding，they may have traffic accidents. If we spend a lot of time on the mobile phones，it may affect our study. What's more，they're bad for our eyes and necks.
In my opinion，we shouldn't spend lots of time on them and we should use them properly.

Dear Jim,
I’m writing to tell you more about the new form of sharing bike--mobike mentioned in your latest letter.
It’s very convenient to use if you have a smartphone. What you do is to find a nearest mobike through the APP, scan the QR code on the bike, and enjoy your trip.
Compared to other forms of sharing bike, the greatest advantage of mobike is that you can easily find one and never worry about where to park it. It is becoming a new trend as a means of transportation, which relieves the traffic pressure and does good to the environment as well.
Hope to ride a mobike with you in China.
Yours,
Li Hua
