Today， as a greener means of transportation， bike-sharing is becoming more and more popular in many cities. It's known that it has many advantages. So it is enjoyed by lots of people.
First of all， it's very convenient for people to go somewhere. Also， it helps toreduce the traffic pressure. There will be less pollution because of bike-sharing. Besides， bike-sharing helps people take more exercise. In this way， it's helpful to people's health.
However， it also brings some problems. For example， some people throw them away after using bikes. Even some people destroy them， and some bikes are stolen by thieves.
In my opinion， everyone should try to be civilized and follow these rules of using bikes. As long as we take good care of bikes， they will make our life better and better， and our environment will be more beautiful.
Dear Miss Li，
I am very happy to know that Datang School will start the summer camp. The middle school students from the Belt and Road countries will join it. I'd like to work forthe summer camp. I want to be a cook，because I want to cook delicious food for students and make them know more about our food culture. I can make many kinds of foods， such as dumplings，noodles and so on. If I become a member of the summer camp， I will prepare delicious food carefully and keep the food clean and safe every day. I will try my best to let students have a wonderful time in our country.
Do you agree that your parents have a second child? Different students have different opinions about it.
Some students agree with the idea. They think， if so， they won't feel lonely and there will always be someone to play with. Besides， if their parents get older or ill， they can take turn to look after them. However， some students disagree. They worry that they will get less love from their parents if another child comes to the family. What's worse， they may not get along well， or even fight against each other.
As for me， I'd love to have a brother or sister as company， so that we can share our happiness and sorrow anytime.
