Tom is a young man. He has a very big dog and he has a very small car, too. He likes playing tennis. Today he plays tennis for two hours at the club and then he wants to go home by car. His dog comes after him, but it does not jump into the same car. It jumps into the next car. "Come here, foolish(愚蠢的) dog!" Tom shouts at it, but the dog still stays in the next car. Tom puts his key into the lock（锁）of the car, but the key does not turn（转动）. Then he looks at the car again. It is not his car! He is in the wrong car! And the dog is in the right car!

    Mary is an American schoolgirl. She is now in Beijing with her parents. She doesn't know Chinese, but she is trying (努力) to study and speak it. She often tries to speak Chinese to her Chinese friends. Sometimes they don't understand (理解) her, because she can't speak Chinese well.

    It's Saturday morning. Mary goes out. She is on her way to the park. She is going there to see a flower show (展览). But she doesn't know how to get there. She asks a Chinese boy. The boy can't understand her. Then she takes out a pen and some paper. She draws flowers on it, gives the picture to the boy and says something about it. The boy smiles and then shows (指给) Mary the way to the park.

A few years ago we moved to a new city, so I had to change schools. On the first day at my new school, I was really {#blank#}1{#/blank#} . I found it hard to make new friends and hardly said a word to anyone for {#blank#}2{#/blank#} . When the morning break started, I went outside and stood on my own. I was feeling really lonely. Towards the end of break, a girl walked up to me. She introduced {#blank#}3{#/blank#} as Monica and started chatting right away. She was also quite new at the school and we soon {#blank#}4{#/blank#} we had a lot in common. We watched the same TV shows, listened to {#blank#}5{#/blank#} types of music, and we were both learning to play the guitar. Also, we lived just a few minutes' walk from each other! 

Monica and I have been really good friends since that day. Naturally we sometimes argue like everyone does but we're very close. 

Hello, I am a box. I am big and green. I have many（许多）things. Look! This is a pencil box. It's white. It is Jack's. He likes white very much. What are in the pencil box? Three pens are in it. What is that? It's an orange. It's Linda's. Oranges are her favorite fruit. Two caps are in me, too. They are John's and Mark's. They lost them in the playground. Whose gloves are those? They are Anna's. She lost them in the library. A. boy found them. You can see an English book in me, too. Whose book is it? I don't know.

People are spending much money buying mystery boxes (盲盒) these days. Usually, there are toys in mystery boxes, but now shops are putting food in them. They are "leftover mystery boxes". 

They are more and more popular in China's cities, such as Beijing, Nanjing and Chengdu. The food inside is near its expiration date (保质期) and will be thrown away if no one buys it. 

Each box costs little money but has a lot of food inside. I buy leftover mystery boxes from an app called Too Good To Go. Each box costs about 3 to 5 pounds (27 to 45 yuan), and there are usually three to four things inside. For example, a box I buy from the coffee shop has three kinds of bread and one cake. The box costs 3 pounds but the original price (原价) is around 10 pounds. Every time I buy a mystery box, I feel happier thinking about how much money I can save. Wasting less food is also good for the environment. 

But the boxes also bring me problems. Because I can't choose what's in the box, sometimes I get the same kind of food. Also, the food may not be nutritious (有营养的) enough. I have to make other dishes, such as a salad, to make the meal healthier.
