Ⅱ.Write a few paragraphs about one of the new inventions (high-speed train, electronic payment, sharing bikes, online shopping, artificial intelligence, etc.). Be sure to use a topic sentence and supporting details to organize your writing.
答案
Sharing bike is my favourite invention. What you do is to find the nearest Mobike through the app on your smartphone, scan the QR code, and enjoy your trip. Here are some advantages as follows.
First of all, Mobike makes our life more convenient. People can go anywhere on public bicycles. What is more, if more people choose to go to school or work by bike, the traffic problems can be reduced gradually. Meanwhile, our environment will be better and better. In addition, riding a bicycle is a dream way to shape our body as well as make us become strong and healthy.
We should use public bicycles as much as possible and be supporters of a low-carbon lifestyle.
