Writing

(Possible answer)

I study in Shenzhen City Middle School. The school is wonderful but there are still some problems. We should do something to improve our school life.

Inside the school，the first problem is the canteen. As you can see，we have only one canteen in our school. We have to stand in a long queue to buy our lunch. We should have another canteen so that we do not waste all our lunchtime queuing up. The next problem is the classrooms. There are only two electric fans in each classroom. In the summer，the classroom becomes so hot that students cannot work well. The school authorities ought to put air-conditioning in the classrooms.

Outside the school，the problem is the road safety. There are no traffic lights or pedestrian crossings outside the school. The traffic is heavy，so careless drivers may cause a bad accident. There should be traffic lights outside the school.

So everybody，let's act now and try our best to make our school a better place.
