    On Sunday we have a trip. We take different bags. Amy's is small and light. It's easy for her to carry it. John's bag is green and heavy. It's hard for him to carry it. Lingling's bag has got four wheels. It's easy for her to carry it. I have a beautiful bag. And I put lots of delicious food in it. It's heavy for me.

    Peter and his father often travel together. They travelled to many places. They went to China last year. They went to the Great Wall by bus. They arrived there at ten o'clock in the morning. The wall is very long and very old. They spent(花费) one hour walking on the wall. There were lots of people. They took many beautiful pictures of the mountains. Peter took a picture of his father. They were very happy.

    Hello! I have a friend. She is tall and thin. She has big eyes and a small red mouth. She has long black hair. She is very beautiful. She is a good student. She likes music, science and sports. She likes beef, fish and rice for lunch. Who is she? You are right! She is Susan.

    Sally is fourteen years old. She was born on October 18th. Mrs. Green is her mother. Today is Sally's birthday.

    There is a party for her. Lots of her friends come to her birthday party. A birthday cake is on the table. There are some bananas, oranges and apples on the table, too. But Sally doesn't like them. What does she want? Can you guess? Just then Sally sees a red card in her mother's hand. It says "Happy birthday to you, dear Sally." There is a nice present for you. Go to your room, you can find it. Sally runs to her room. Ah, a beautiful skirt! How happy she is!

    My name is Jack. I go to school from Monday to Friday. Every morning I get up at six thirty. I have four classes in the morning and two classes in the afternoon. I have Chinese, English, maths and science on Monday morning. I like Fridays very much, because I have PE. I can play sports. Football is my favourite sport. I also play football on the weekend. I think(我认为)we should play sports every day.
