2 . China is determined to land its astronauts on the moon and set up a scientific station there,according to a project leader.

Zhou Yanfei,deputy chief designer of China's manned space program,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,explore ways to develop lunar resources and strengthen the nation's space capabilities.

＂A new wave of lunar explorations has been emerging in the world,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,"he said in a report delivered at the 2020 China Space Conference in Fuzhou,Fujian province."Unlike other nations,China must depend on its own science and technology to realize our goals."

The country is independently able to land its astronauts on the moon because it has the technologies,a group of well-trained,innovative professionals and high-efficiency research and management systems,Zhou said."However,our existing carrier rockets can't perform landing missions to the moon because they are not powerful enough.The Shenzhou- series manned spaceships are not suitable for lunar expeditions.We don't have a lunar landing capsule,"he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface.

To solve the problem, we set out to produce a powerful launch vehicle. Zhou said researchers thought about two approaches-making a new heavy-lift rocket,or adjusting the next-generation rocket designed to carry astronauts,which is under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.

The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 meters tall,with a diameter of 5 meters,which would make it almost twice as tall as the Long March 5,currently the biggest of China's rockets.

1. Which is NOT the goal of the manned lunar mission?

A．To explore lunar resources.

B．To perform scientific experiments.

C．To set up a scientific station.

A．China is not capable of pursuing the manned lunar program.

B．There are still difficulties in pursuing the manned lunar program.

C．There are a series of steps in the Manned Lunar program.

D．It is manageable to carry out the Manned Lunar program.

3. What can we infer from the passage?

A．Nations must depend on themselves to explore the moon.

B．The Long March 5 is the biggest of China's rocket.

C．The newly-designed rocket will not carry astronauts.

D．Producing a powerful launch vehicle is the most difficult part in the program.

Once upon a time, there was an old man who couldn't read or write. When he was little, his family was so poor that he couldn't attend school. But he always dreamed of being able to read.

One day, he took his seven-year-old grandson to school.

Since he didn't have anything to do that day, he didn't leave immediately. Instead, he stood outside his grandson's classroom and looked in through the window.

The kids' teacher, who was an old man in his fifties, entered the classroom when the class began. The teacher was wearing thick glasses. He started teaching. Through watching him, the old man found something interesting, He noticed that the teacher could read nothing without putting his glasses on. As soon as he put on his glasses, he could read very well.

“How amazing! said the old man to himself.

He waited outside the classroom until the class was over and stopped the teacher.

“Excuse me, sir," said the old man to the teacher.

“Yes?” said the teacher.

“I noticed something amazing. You can't read without the glasses, right?" said the old man.

"Yes, that's true. I can read nothing without them," replied the teacher.

"But you can read once you put them on, can't you?" asked the old man.

"Yes, that's true, too," replied the teacher, wondering why the old man was asking such strange questions.

The teacher looked at the old man, who left in a hurry with a big smile on his face.

5 . Slow Walking and Ageing

Getting old might not be something that’s yet to cross your mind.     1    , so it’s something I’m sure we’d all like to control. That’s why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.

    2    . To walk 10,000 steps a day or do three brisk 10-minute walks plays an effective role in our health. But the latest research might put a spring in your step if you’re accustomed to walking at a fast pace. That’s because the speed at which people walk is a sign of how much their brains, as well as their bodies, are ageing.

According to the result of those tested, slower walkers tended to show signs of “accelerated ageing”. Their lungs, teeth and immune systems were in worse shape than those who walked faster.    3    . Professor Terrie E Moffitt, has proved that a slow walk is a problem sign decades before old age.

This might be seen as a wake-up call for people with a slower gait who might feel it’s time to work out and get fitter. But it might be too late; researchers predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three.    4    .

So, what’s the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing.    5    . Any steps we can take to prolong a good mental and physical state is a no brainer!

A．Everyone wishes to keep young

B．There are various ways to exercise

C．We all know that regular exercise is good for us

D．But ageing is unavoidably going to get the better of us one day

E．This might help us make lifestyle changes while we’re still young and healthy

F．In other words, some signs even in early life will show who will live younger and healthier

G．To add insult to injury, the result also indicates the faces of slower walkers usually look older and they have smaller brains

6 . Exercise could not only benefit your body, but also improve your memory, researchers found recently. In their paper published on Monday, researchers from the University of California, Irvine in the United States and the University of Tsukuba in Japan introduced their experiment and conclusion.

Scientists invited 36 volunteers who were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they were shown pictures like broccoli（西兰花）or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. ^u The memory task was really quite challenging , "   said Michael Yassa,co-author of the study and a neuroscientist （神经科学家）at the University of California, Irvine. "We used very tricky similar items to see if they would remember whether it was this exact picnic basket versus （对抗）that picnic basket. "

Researchers also scanned brains of some, of the participants during the experiment. They found strengthened communication between regions involved in the storage and recollection of memories in brains of those who had exercised. This suggested that just 10 minutes of light exercise like walking,yoga or Tai Chi might increase memory power.

As all the volunteers in the experiment were relatively young, researchers are still working to look at the effects of light exercise on older people. "Our future goal is to try to develop an exercise prescription（处方） that can be used by older adults who might have disabilities or mobility impairments,but can still adopt very simple exercise rules of life and be able to,perhaps,delay cognitive decline temporarily," said Yassa.

1. What did the researchers find from the experiment mentioned in the text?

A．Regular exercise is of benefit to the memory of all people.

B．Just a short period of exercise better young people's memory power.

C．Older people can also improve their cognitive power by exercising regularly.

C．The items to be distinguished were extremely similar.

D．The questions asked by the scientists were too complicated.

3. What's the purpose of the text?

7 . A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot 's operator.

The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1 ,000 meters in the underground p ipeline.

The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers. " Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible. "

With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot ' s developer said.

Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company. " No digging is required and there is no need to interrupt traffic," Ge added.

1. What does Paragraph 2 mainly tell us about the pipeline robot?

A．Its developer.

B．Its components.

C．Its characteristics.

D．Its outward appearance.

2. What is the toughest in managing underground pipelines in cities?

A．Locating the position where the pipelines are.

B．Handling the poisonous gases in sewage pipes,

C．Arranging the repair and maintenance of pipelines.

D．Discovering flaws in the sewage and rainwater pipelines.

3. What does the author intend to do in Paragraph 5?

A．Add some background information.

B．Introduce a new topic for discussion.

C．Summarize the previous paragraphs.

D．Present some new functions of robots.

4. What is Ge Shengli's attitude towards the pipeline robots?

A．Doubtful.	B．Appreciative.
