More children in China are putting on weight.In 2018，16 percent of Chinese children were overweight，according to the National Health Commission（NHC）.
Being too fat is bad for children' s health.According to the World Health Organization （WHO），overweight children are more likely to develop diseases like diabetes（糖尿病） at a younger age.This can lead to a higher chance of earlier death.
On Oct 23rd，the NHC，together with five other national departments，worked out a plan.The plan aims to reduce the growth of fatness among children aged 0﹣18 years by 70 percent from 2020 to 2030，Xinhua reported.
Kids are putting on weight because of changes in their diet and lifestyle，according to experts.Too much schoolwork and greater use of electronic devices（ 电子产品） could also be a cause.
According to the plan，teachers should not allow their classes to run too late or too early.They should make sure that students have breaks and enough physical（躯体上的） activity.School students should have at least three hours of active physical activity each week.
Parents should reduce their children's use of electronic devices and stop their children from eating foods that are high in sugar，fat and salt.

People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.
But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.
Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.
Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.What is genius according to Thomas Edison?
| A．Hard thinking. | B．Hard work. | C．Useful ideas. | D．Useful inventions. |
How did Edison always deal with the secrets of nature after exploring them?
| A．To write down what he had learned. |
| B．To carry out a new experiment. |
| C．To make them useful in life. |
| D．To share them with others. |
What does the last sentence in the passage mean?
| A．Edison was born to be a great inventor. |
| B．Edison was able to live another 100 years. |
| C．Edison was ready to make his 100th invention. |
| D．Life was too short for Edison to work for human beings. |
More and more people think it necessary to study in an English-speaking country and it didn’t take long at all for me to decide to come and study in UK.
I have been used to school life since I came here two months ago, and I am starting to enjoy most of my time in here. School starts at 9 o’clock every morning, and every Monday, Wednesday and Friday we have long days, in which we have 9 lessons and school finishes at 4 o’clock. Every Tuesday, Thursday and Saturday we have short days, in which we have only 6 lessons and finish at 1 o’clock. After lessons, we have 2 hours of activity time, when you can choose from a number of activities, including many sports, such as rugby(英式橄榄球) , football, basketball and tennis.
As a boarder(寄宿者), the quality of food is something I consider very important, and Merchiston has not let me down. The school kitchens are run by a professional company, and the quality of food is excellent, and they are always trying to make the diet healthy. One of the obvious advantages of being a boarder is that we can have breakfast in the school, which means we don’t have to pull ourselves out of bed as early as the day pupils!How many lessons do the students have every week in this school?
| A．15 | B．45 | C．27 | D．18 |
The passage mainly tells us about __________________.
| A．the writer’s school life in the UK as a boarder |
| B．the writer’s opinion of the school life in the UK |
| C．the differences in school life between China and the UK |
| D．the boarder life in a British middle school |
Which of the following has the closest meaning to the underlined phrase “ let me down” in the passage?
| A．made me blue | B．cheered me up |
| C．encouraged me | D．made me surprised |
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (彗星) in the direction of Earth, and its orbit (轨道) will be changed. Our world will then be sent moving into a safer older part of the solar system.
This idea for improving our climate comes from a group of US NASA (美国航空航天局) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—hopefully doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy (重力势能) to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter (木星) or Saturn(土星). The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to worldwide warming, although the team was actually worried about a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying sides, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth—with deadly results.
There is also the question of the moon. As the present issue of Scientific American magazine points out, if Earth was pushed out of its present location, it is “most likely the moon would be stripped (剥离) away from Earth,” it states. This would greatly change our planet’s climate.What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
If the plan is successful, Earth will have a working life of ________ years.
| A．12 billion | B．6 billion | C．18 billion | D．24 billion |
What serious problems might the plan cause according to the passage?
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might die because of the coldness. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
What does the underlined word “compromise” mean?
| A．provide | B．benefit (受益) | C．share | D．endanger |
It’s in the 2010s.You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks what you’ve been thinking about lately. When you leave, she gives you some medicine, but also a list of thinking skills that you are supposed to practice daily. She says that the way you think is causing some of your illness.
Doctors and other scientists who study the human mind and try to explain why people act in the way that they do, called psychologists (心理学家), are starting to believe it. You know that your brain (脑) is connected to every part of your body through your nervous system (神经系统). Now scientists have proved that how you think and feel can have an influence on the health of your body.
Stress is caused whenever there is a problem or a change in your life. Of course, everybody has stress more or less; nobody’s life is perfect. In fact, stress is necessary. Without stress, we would never learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you. It can weaken your body’s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident.
When you feel stressed, your brain sends a message to your body to produce a chemical called adrenaline (肾上腺素). Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress. Problems like endless homework or troubles with your family are the kind of things you can’t fight or run away from, so you don’t use up all that adrenaline. It just stays bottled up inside you, and that’s what can do something bad to you.
What can you do about stress? First, you can try to find ways to change things so you aren’t under so much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out with your family or your friends. But sometimes you can’t change a stressful situation. Sometimes you don’t even want to. A big change might be a good change, but it will still be stressful.
The link (关联) between your body and brain works in two ways. Your body can help your mind deal with stress. If you are under stress, you need to take especially good care of your body. It’s important to get enough sleep and eat nutritious (有营养的) meals. Some people take a vitamin-mineral pill every day. Another thing that you can do is daily exercise. If you go walking or do aerobic dancing or work out at the gym (体育馆), you give your body a chance to burn up some of that adrenaline. Of course, a person who isn’t used to much physical activity should start slowly. Anyone with a continuing physical problem should check with a doctor before starting any exercise programs.Which of the following is TRUE according to the passage?
| A．You shouldn’t go to the gym if you are under stress. |
| B．One can do his homework to burn up adrenaline. |
| C．Disease and accidents are caused by stress. |
| D．Everyone needs stress to improve himself. |
From the last sentence of Paragraph 5 we can infer (推断) that _____________.
| A．it’s difficult to change a stressful situation |
| B．it’s not stressful when a good change takes place |
| C．a big change will cause another stressful situation |
| D．a stressful situation can’t be changed without any effort |
What is probably the best title for this passage?
| A．The Body-Brain Link | B．The Causes of Stress |
| C．The Advice on Health | D．The Nervous System |
Once there was a piano player in a bar (酒吧). People came just to hear him play. But one night, a lady asked him to sing a song.
“I don’t sing,” said the man.
But the lady told the waiter, “I’m tired of listening to the piano. I want the player to sing!”
