A Long March 5 rocket took off from the Wenchang Space Launch Site in Hainan province on May 3, 2024. After flying for about 37 minutes, it successfully placed the Chang’e 6 robotic lunar probe(月球探测器)into an Earth-moon transfer trajectory(转移轨道). Several days later the probe was programmed to land on the moon’s far side and started its tasks, which would last about 53 days.
This is the world’s first try to bring samples(样本)from the moon’s far side. For China, it’s the second sample-return moon journey. Chang’e 5 successfully brought samples from the moon in the winter of 2020. Up to now, 10 moon sample-return tasks have been carried out by the United States, the former Soviet Union(前苏联)and China, but all these samples were collected from the moon’s near side.
The moon’s far side has always been a subject of scientific wonder because of its many mysteries. It’s facing away from Earth and it can never be seen from Earth. It was once called the “dark side of the moon” even though it receives just as much sunlight as the near side.
Chinese researchers have found that the soil on the far side is much thicker than that on the near side, but they haven’t found out the reason. Samples brought back by Chang’e 5 have helped scientists find that there were volcanic(火山的)activities on the near side around 2 billion years ago. Some scientists thought maybe volcanoes became inactive on the far side about 4 billion years ago. Is it true? Samples from the far side will allow them to know the answer.
“Comparing the make-up of the far side samples from Chang’e 6 with those collected from the near side will be of great scientific value to the international community,” said Martin Sweeting, a famous professor of space engineering.

You have waited 45 minutes for the valuable 10 minutes’ break. But when the bell for the next class rings, you can’t believe how quickly time has passed. If you have this experience, you’ll know how time flies when you are having fun and drags when you are bored. Now scientists have come up with a reason why this happens.
They have found that the brain changes its way to work according to how we direct our attention to a task. When we are bored, we pay more attention to how time is passing. And this makes our brains think the clock is ticking more slowly.
Recently some researchers who want to understand the conditions carried out an experiment. In the experiment, twelve volunteers watched a picture while researchers monitored(关注)their brain activity.
The volunteers were told to first notice how long a picture appeared, then the color of the picture, and thirdly, study the both. The results showed that the brain was more active when the volunteers paid attention to more subjects.
It is thought that if the brain is busy noticing many aspects(方面)of a task, it has to spread its resources, and pays less attention to the clock. Therefore, time seems to go quickly. If the brain is not so active, it spends its full energy on the passing of time. As a result, time seems to move slowly.
Next time you feel bored in class, perhaps you should concentrate(专心于) on what the teacher is saying.What does the underlined word “drags” probably mean?
A.passes slowly | B.runs quickly. |
C.moves actively | D.goes silently |
What have the scientists found?
A.Time goes by fast when we have nothing to do. |
B.The ten minutes’ break is important to students. |
C.The brain works in different ways in different situations. |
D.Students pay more attention to the pictures than the passing of time. |
Which of the following is TRUE according to the passage?
A.We will be full of energy if we’re busy. |
B.Concentrating on things is a way to make people less bored. |
C.Time goes slowly when the brain is noticing many things at the same time. |
D.We should pay no attention to time when we are doing something. |
Which is the best title of the passage?
A.The best way to save time |
B.The importance of planning time |

D.The reason for time flying and dragging |
Zoos are places where different kinds of animals are Kept and shown for the public. At most modern zoos people can see, smell and hear animals in their natural way. Some zoos even have “friendship farms” where people can touch some of the animals. Here are four reasons why people need zoos.
Firstly, zoos educate people about animals and their natural environment. They give interesting information about each animal, such as where it comes from and how it lives. Special teachers at the zoo help children to understand more about the animals. Trained guides show visitors around the zoo.
Secondly, zoos are working hard to find out more about animals. New knowledge leads to improved ways of looking after animals in the zoo, and better understanding of the same animals in the wild.
Thirdly, zoos play a part in protecting animals and stopping them from disappearing. Zoos work together with each other to help the animals in danger. For example, gorillas(大猩猩) from Taronga Zoo were sent to live with gorillas at the Melbourne Zoo in the hope that they would give birth to babies.
Finally, zoos are important for people’s enjoyment. People enjoy getting close to animals without having to cross the plains(平原)of Africa or climb the mountains of China. In the past, animal shows were common in zoos. Visitors were excited by monkeys in human clothes, and they even took rides on elephants or horses. However, today people prefer to see animals behaving naturally.
So a modern zoo is a place where animals are well cared for. Special teachers at the zoo___________.
A.show visitors around the zoo |
B.ride elephants or horses |
C.look after animals in danger |
D.help children know about animals |
According to Paragraph 5, visitors to the zoos enjoy themselves because they_____
A.can get close to animals |
B.prefer to cross plains |
C.like climbing mountains |
D.can organize animal shows |
Which of the following is NOT TRUE according to the passage?
A.Modern zoos have improved ways of looking after animals. |
B.At modern zoos people like to see animals behaving naturally. |
C.At modern zoos baby animals are usually born on the “friendship farms”. |
D.Modern zoos educate people about animals and their natural environment. |
One day in the eighth grade, I was taking a Math Test on basic trigonometry (三角学). Now for a middle school student, there was nothing basic at all about it. So I had studied for about two hours the night before. After reviewing it for some time, I had started to understand it, so then I closed the book and _________. However, it was not until midnight that I fell asleep. The next day, when I got the test, it might as well have been written in Serbian (which I don’t know how to read). I tried my best to work out the hard problems, but the numbers I came up with were strange. I sat back on my chair and looked for any possible answers, but I could not remember anything or think correctly. I started thinking about my dad coming home from work to find that I failed the test …
“How could you have failed the test? I am certain that nobody else in the whole class got as bad a grade as you did!”
Naturally I didn’t want that to happen. My dad was also really busy at work at present, so I was afraid that this might make him mad. When feeling hopeless, I noticed that my table partner was writing fast on his test. I could see smoke rising up from how fast he was writing. I was attracted to look over at his test, but then the many bad results I had heard about cheating (作弊) came into my mind. I reasoned that if I started cheating now, it would be hard to give up that habit during high school. In the end, I decided not to copy his answers, and got a B- on that test. Even though my dad gave me a hard time about it, it would have been a lot worse if he found out that I had given in and cheated.The writer might feel ______ before the Math Test.
A.surprised | B.relaxed |
C.worried | D.excited |

Life in the year 3044 is very different from life in the 21st century(世纪). We still do many of the things you did, but we do them differently. For example, we now have e-friends to help us and keep us company. An e-friend is a machine that looks just like a human being. It can walk and talk like humans and can do almost the same things as we human beings do. My e-friend is a lot like me and we have much fun together. She helps me with my homework and we often go swimming. She is computerized to take care of me in case (万一) anything happens, so I always feel safe when we are together. She can also send me messages, just like old-fashioned e-mail, and I can download (下载)information from her memory chip. It’s so great to have an e-friend – I feel never lonely and I always have someone to talk to.
Actually, I would plan to tell you more about life in the year 3044, I have to send my e-friend to clean up my room, though. Maybe one day I will be able to fly back in time rocket and visit you and old friends. Looking forward to! An e-friend can do the following EXCEPT________.
