    I have a new teacher. Her name is Li Ying. She has glasses and short black hair. She has two big eyes and a small mouth. She is tall and thin. She is very friendly. She likes reading books very much. There are many books in her study. I like my new teacher very much.

    I am Robin Today is Saturday. Tomorrow afternoon，I am going to the bookstore by bus. The bookstore is in front of the Italian restaurant. In the bookstore，I am going to buy a dictionary and a science book for my grandpa. Because my grandpa likes science very much. He has lots of science books In the evening，I'm going to visit my grandparent. We are going to have dinner together. After dinner, we are going to see a film about space travel. That will be fun! What about your weekend?

    Our future on Earth looks very bad. We are throwing rubbish on our land. We can't breathe the air. The sea is dirty, too. I visit some relatives recently in a small village. They grow their own food. They're not rich, but they are happy and healthy. We should close some factories, because they are producing useless products. That would reduce (减少) rubbish and air pollution. We should recycle more. and improve (提高) public transport. Overpopulation (人口过多) is a big problem in big cities. We should give up useless factories and get back to a simple way of life.
