    Tom and Mike are good friends. They are good to kids. They want to find summer jobs. One day Tom tells Mike that Beidaihe Kids Summer Camp needs help with sports, music and computers. They are both very glad to hear this.

    Tom can play basketball and volleyball, and he can swim, too. Mike can play the violin, the drums and the guitar, and he also likes soccer. Tom and Mike like computers very much. Can they join the Summer Camp?

    There's a park near my home. People like to go to this park after work, because they like the beautiful flowers and clean air in the park. Some of them go there every day. Look! That's Mr. King. He is taking a photo for his son, Jim. They look very happy. Some boys are playing games. Some boys are playing football. Lucy and Lily are standing under a tree. They're talking. There's a small river in the park. We can see some boats on the water. Some children are sitting in the boats with their parents. Listen! A girl is singing.

    This is really a nice park. We all like it very much.

    It is Sunday afternoon. Mary goes shopping with her mother. Her mother wants to buy some food for supper. Mary wants to buy a T-shirt and some school things. They come to a shop.

     "What does your shop sell?" Mary asks. "A lot of things," the girl in the shop says. "You can buy food, drinks, clothes and school things in our shop."

    Mary and her mother go into the shop. There are many people in the shop. Mary finds a nice white T-shirt.

    "How much is the T-shirt?" Mary asks the girl in the shop.

    "It's eighty yuan."

    "That's too dear. Do you have a cheap one?"

    "What about the green one? It looks nice. And it's only thirty yuan."

    "OK, thanks a lot." "You are welcome."

    After that, Mary buys some school things too. Her mother buys a lot of food, like bread, cakes, meat and fish. They get home very late.

Many social media posts(社交媒体帖子) may let you believe that everyone is happy all the time, but being happy all the time is not possible.

As a teenager, you probably expected to get good grades in an exam or to win the most important basketball game, but it didn't happen. Good results make you happy and bad results make you sad. But sadness can drive you to improve yourself next time.

However, when people get into sadness for a long time and it starts to affect(影响) their lives, it's called depression (抑郁). You don't want to get out of bed. You don't feel like studýing or going out with your friends. I remember the same feeling when my dog Rebel died in an accident. I remember that he followed me to school. Now he was gone, and I lost all interests to do anything.

My parents told me dogs don't live forever. What was more, Rebel had a good life. If Ihad a good life, Rebel must be happy, too.

Depression is not a person's mistake. It's normal to feel sad sometimes. Many great people, like the comedy actor Jim Carrey, once get depressed. But you should know what to do to stop depression or make yourself less depressed.

When you feel down, you must not keep yourself away from the world. Try to share your feelings with a family member or a good friend. Staying at home by yourself will make you more lonely. You should stand up, open the window, and throw away (抛弃) the sadness.
