Once in a physics class, the teacher asked students, “Why do we have brakes (刹车) in our cars?” Soon, students gave different answers. A student stood up and answered, “Sir, to ________ the car.” Another one said, “To slow down the ________ of the car.”

However, ________ of the answers was the same as the teacher’s. Then he said, “All of your answers are right. But in my opinion, the brakes in the car make us able to drive much ________ .”

“If the car has no brakes, how fast are we ready to drive? It is the brakes in the car that help us drive fast and safely.” Listening to this, the whole class was silent ________ no one had thought about this answer.

At the same time, there are many such “brakes” in our life, which ________ to stop us. For example, our parents may ask us about decisions (决定) in life. Their questions or ________ may be seen as “brakes” which stand in our way. But we can see them as our supporters which can protect us. Sometimes, we ________ stop, so that we can do better.

In fact, it is the “brakes” in life that help us a lot. ________ these “brakes”, we could lose our direction or get into danger. So we need to understand that “brakes”in our life do not mean pushing us back ________ making us move forward more quickly than before.

Do you like travelling? Do you think travelling is tiring or enjoyable? In the year 2070, most of you will be about 60 years old. The good news is that travelling might become smarter by that time. European airline EasyJet has made some predictions (预测) and showed them to the public: The Future Travel Report. Let’s take a look at some of their ideas.

Paper passports will be a thing of the past. You will use “heartbeat passports” instead. According to experts, everyone’s heartbeat is different. So your heartbeat will be taken and be used to tell who you are.

The seats on the plane will no longer be “one size fits all”. You’ll be able to book a seat according to your body type. The seat might even be able to cool or warm you until you feel comfortable with the temperature. There will also be no more screens on the back of your seats. A special machine in the future could show movies straight in front of your eyes.

If you hate packing clothes, you may not need to do it in the future. Before you fly, your body shape will be taken. And when you arrive, you’ll find a wardrobe filled with 3D-printed clothes in your size. When you leave, the clothes can be recycled and reprinted for the next person. You can also 3D print whatever you want to eat.

If you like to visit historic sites (历史古迹), augmented reality (AR，增强现实) will change the game. Wearing a headset, you can see what happened at a historic site, such as a famous battle. You may even be able to sit among the cheering people at the first Olympic Games.

Peter has worked and lived in Shandong Province for almost five years. When his boss asked him to Rizhao     39     , he realized that it was a good chance to visit it. Rizhao is famous for its beautiful beaches and delicious seafood. Rizhao certainly goes beyond that! It is also “hometown of green tea” in     40     China. Rizhao is in the southeast of Shandong Province near the Yellow Sea. It has pleasant weather, rich soil, and enough sunlight. All these make it special for growing high-quality green tea. Peter had the chance to     41     tea leaves for the first time in his life. “This is the first time I’ve learned about Chinese tea culture. After a hard day’s work, I     42    . However, it’s fantastic! I want to travel and have more exciting     43     in the future.” Peter said with a smile on his face.

We all know doing exercise makes us healthy. But many of us don’t know which is better, to exercise in the day     44     at night. Dr. Yang, a famous sleep doctor,     45     (advice) people to do outdoor exercise for     46     least 30 minutes a day in the daytime.

Dr. Yang has     47     (do) research (研究) on sports and sleep for years. He finds out that those who exercise in     48     (nature) light for half an hour every day have better sleep and more energy. Dr. Yang     49     (he) gets up at 6:30 a.m. Then he usually takes a walk outside. Sometimes, he walks his two dogs in the park in the afternoon with his sunglasses left at home.

Many schools put Dr. Yang’s findings into practice. They made it     50     rule that students should do outdoor exercise once or     51     (two) a day. In some schools, students even formed outdoor running clubs. After some time, most students said they benefited (受益) a lot from outdoor exercise. Now they sleep better and concentrate (集中)     52     (much) on their studies.

Some students are now thinking about     53     (invite) their teachers to join them in their daily runs.

Diego was looking at the old guitar on the wall of his house. The guitar had an old story. Diego’s grandfather, Miguel, played it everywhere he went. His playing was so good that people came to listen whenever he played it.

Diego knew this story well. He wanted to be like his grandfather. So, he started to learn to play the guitar when he was little. After he grew up, he had his own band (乐队). So, his grandfather gave him the guitar as a gift.

Diego’s grandfather saw how some singers broke their guitars during big rock shows. He didn’t like this. He thought people should take care of their guitars.

“Make sure you’ll never do this to our guitar,” he said to Diego.

“Of course,” said Diego.

Diego was now a big rockstar. Once he brought this guitar on the stage and played amazing songs with it. All his family were watching and felt very happy. At the end of the show, Diego got so excited that he lifted the guitar in the air. When everyone thought that he was going to break it, he slowly took a bow (鞠躬).

He always remembered what his grandfather told him, “If you really love rock, love your guitar. It is your friend, not just a thing.” Diego kept his word. He showed his love for rock music.
