China covers large areas and has a great population. Different living habits have always been an interesting topic in the country. Recently, another difference between southern Chinese and northern Chinese became a hot one: the way people shop at markets.

    People from southern China say that they always buy what they need for just one or two meals. It is normal for them to buy half of a Chinese cabbage, two potatoes and 0.25 kilogram of beef at a time.

    However, one may be laughed at if he does this in the north. Instead, buying vegetables and meat enough for a week is usual. Also, you can buy a small amount (数量) of fruit, such as a single apple or pear, each time in the south. Shop owners even help you peel and cut them. But shop owners in the north hardly offer such service. And many fruits are sold in baskets and boxes.

    The difference could be due to the different weather.

    Food can be kept for a long time in the north, as it is usually cold and dry there. Many northern Chinese have the habit of storing food, especially for the long winter. But the hot and wet weather in the south makes southern Chinese buy just enough food for one meal or one day, or else the food may go bad.

Hello, everyone. I am Eric, a student in No. I Middle School. Now let me tell you about my favorite teacher. 

My favorite teacher is Mrs. Plath. She is my English teacher. She is my friend John's aunt, too. She is good to every student in my class. Everyone likes her. She gives us some interesting homework. It's relaxing for me to do the homework. 

Now Mrs. Plath is 40. She has many things to do. She has three classes a day. And she helps in the reading club after school. She helps children read and makes them love books. 

I think good teachers can make students love school. They have a good influence (影响) on their students. Mrs. Plath is a good teacher. I want to thank her. I want to be a teacher like her.
