Dreams
"Dreams(梦) may be more important than sleep. We all need to dream," some scientists say.
Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That maybe because the dreamer is worrying about something. Dreaming maybe a way of trying to find an answer.
Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.
Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear(消失) quickly from memory(记忆).
Too much dreaming can be harmful(有害的). The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep and still wake up tired.

Have you ever been swimming in a pond, stream, or lake and had a leech(水蛭) stick on you? You probably shouted and tried to force it away as fast as you could. But leeches aren’t really sick, and sometimes they can save lives.
In ancient Egypt and later medieval(中世纪) Europe, doctors put leeches on patients. They believed that the spineless wormlike living things can cure all kinds of illnesses by sucking(吮吸) a patient’s blood. In Europe and in the United States, millions of leeches were used throughout the 1800s. Doctors used leeches to treat a number of illnesses, from obesity to headaches. People soon learned that leeches could not cure most diseases and were not a good treatment for patients. However in 1985, a Harvard University doctor changed people’s thinking once again. He was trying to reattach(重新接上) a patient’s ear, which had been cut off. He had trouble reconnecting the veins because the patient’s blood kept clotting(凝). He used a leech to draw out the blood and saved the ear.
Since then, leeches have often been used in surgery where body parts are reattached. During surgery, a leech is placed on the area where the surgeon does not want the blood to pool and clot. Then the leech produces a thing that keeps the veins(静脉) open and stops the blood from clotting. The leech sucks up excess blood, allowing fresh blood to flow, which helps the patient get well.
Some people are scared to death at the thought of having a blood sucking thing attached to them. But why not welcome a leech if it can save your life?

The world’s largest radio telescope was finished in China.
FAST is a five-hundred-metre telescope. It is also called Tian-yan (“The Eye of Heaven”), with a dish the size of 30 football grounds, deep in the mountains of south-west China’s Guizhou Province. The giant dish is built on a bowl-like valley.
The surrounding area has “radio silence” as there are no towns and cities within a 5-kilometre radius(半径范围）and only one county centre within 25 kilometres.
FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will e able to pick up weaker signals.
The radio telescope is like an ear, listening to meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系)and explore the origins of the universe. “Any of its discoveries will lead to a Nobel Prize,” said Joseph Taylor, a Nobel Prize winner.
The telescope is expected to remain the global leader for the next 10 to 20 years.
1.The passage may appear in the “_______________” section of a newspaper.
A.business B.advertisement C.literature D.science
2.FAST is used to ________________.
A.explore the origins of human beings
B.receive distant radio messages from the universe
C.watch the beautiful scenery of the Galaxy
D.help scientists to win the Nobel Prize in the future
3.The sentence “The FAST project began in 2011.”can be put at the beginning of ____________.
