People spend about one third of their lives sleeping, and during that time, most people experience strange and colorful dreams every night. But why do we dream? This question has interested scientists for hundreds of years, and they have done different kinds of research to look for a reasonable explanation. Some scientists believe that dreams help our brain organize information. When we sleep, our mind deals with the things we see, hear and learn during the day. It connects new information with old memories properly. In this way, dreams are like a “cleaning and sorting” system for our memory, making our brain work more efficiently. Others hold the opinion that dreams prepare us for real life. In dreams, we may face dangerous or difficult situations, which can help us practice and deal with problems better when we are awake. Some dreams also show our true feelings and unconscious wishes that we may not notice or express in our daily life. Although they have different ideas, they have found one thing in common: not all dreams have deep or special meanings. Sometimes, dreams are just caused by body tiredness or strange thoughts before going to bed. They may be meaningless and have no clear message at all. Until now, scientists still do not have a final certain answer. They will keep studying the mystery of dreams. But there is no doubt that understanding dreams better may help humans know more about the secrets of the human mind and body. 1. What does the brain do during sleep according to Paragraph 2? A. It stops organizing information to have a good rest. B. It cleans the room and sorts the rubbish efficiently. C. It deals with daily information and connects it with old memories. D. It only helps with the difficult situations we may face in our daily life. 2. Which of the following is a fact instead of an opinion? A. Scientists have done different kinds of research about dreaming. B. Scientists believe that dreams help our brain organize information. C. Dreams can surely help us practice and deal with problems better in real life. D. Understanding dreams may help humans know more about our mind and body. 3. What does the underlined word “They” refer to? A. Dreams. B. Thoughts. C. Scientists. D. Memories 4. How is the text mainly organized? A. By telling a story and expressing feelings. B.

A. ①②→③④→⑤ B. ①→②③④→⑤ C. ①②→③→④⑤ D. ①→②→③④→⑤ 八、完形填空 When we look at pretty things like art, our brain’s reward system is turned on to give us a feeling of happiness.

However, many students do not get enough sleep. They often stay up late using phones or playing games. Good sleep improves our memory. When we sleep, our brain organizes the information we learn during the day. That is why students with enough sleep usually perform better in tests. Sleep also helps the body grow and repair itself. Teenagers need more sleep than adults. Most young people need at least eight hours of sleep every night to keep energetic. If you sleep badly, you will feel tired easily. You may become impatient and cannot focus in class. To sleep well, you should stop using electronic devices an hour before bedtime. Gentle music and light reading are also helpful. Sleep is not a waste of time. It is one of the easiest and most useful ways to stay healthy and happy. Task 1: Critical Thinking（根据文章内容回答下列问题） 1.
