In the universe (宇宙) , as we all know, there is the Sun, the Moon, the Earth and a large number of stars. Through our Geography lessons, we know that the Sun is a star, the Earth is a planet and the Moon is a satellite (卫星) . We also know the Earth goes around the Sun and the Moon goes around the Earth. We have day and night because the Earth keeps turning all the time When our part of the Earth turns to the Sun, it is day. When our part of the Earth turns away from the Sun, it is night.
Just because the Moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are farther and small things also look bigger when they are nearer.
The Sun is big enough to give out strong light. The Moon can’t give out any light at all, but it looks quite bright, too. Why? In fact, the light from the Moon comes from the Sun. The Moon looks much bigger and brighter than the stars, but in fact the stars are much bigger and brighter than the Moon. They look smaller than the Moon also because they are farther away from the Earth.
There are many other facts about the universe and we should study hard to know more.

【推荐1】As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health.
The harm of the radiation won’t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.
Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion (爆炸) in space in 1999 made a cloud of 300, 000 fragment (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage (损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth.
We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.

【推荐3】Many people know that rubbish is a big problem on the planet Earth. What many people don’t know is that junk（垃圾）has become a problem in outer space too.
According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes （望远镜）. There are also millions of smaller pieces of junk that we can’t see.
Objects, like bits of old space rockets（火箭）or satellites（卫星）, move around the planet at very high speed so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage （损害）the space tool.
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional （额外的）space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth’s atmosphere （大气层）after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists also suggest different ways to clean up space junk. In England, scientists are testing a special net that can be sent into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely dealt with.
“The problem is becoming more challenging because we’re sending more objects into space to help people use their mobile phones and computers,” says Marco Castronuovo, an Italian space researcher.
“The time to act is now. The longer we leave the problem, the bigger it will become,” he says.

It’s believed that fish can’t remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don’t be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.
In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish still went to the same place where they first got food.
In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence (证据) until the latest findings.
Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to live in the wild. “If fish are able to remember that a certain area contains (容纳) safe food, they will be able to go back to that area without putting their lives in danger,” lead researcher Trevor Hamilton told Live Science.
So next time you are watching your pet fish from outside the tank, perhaps you should feel closer to them—they may remember who you are.
1. We often feel sorry for fish because every moment in their lives is new.2. To know if fish can find food easily, the researchers carry out the research.
3. The underlined word “tank” in Paragraph 2 means a container for keeping fish.
4. Fish are often in danger when they look for food.

Years ago, as we know, zoos kept animals in cages. Cages made it easy for visitors to see the animals, but a small cage is not a good place for an animal to live in.
Today animals live in open areas. There are usually plants and a little lake around, like the animals' habitats. Visitors usually stay in the bus to see the animals outside.
Zoos help to protect all kinds of animals. They protect animals in the zoo as well as animals in the wild. How do they do this? Zoos tell people how animals live in the wild and how to help protect their environment.
The number of many kinds of plants and animals is becoming smaller and smaller. Mammoths, which are related with Asia elephants, are now extinct（已灭绝的.Scientists say that
Zoos are working together to help animals-our friends.

ChatGPT, a smart AI chat-bot (聊天机器人) tool, has swept the education world in the past months. According to a US survey of more than 1,000 students, over 89 percent of them have used ChatGPT to help with a homework assignment.
Developed by US company OpenAI, ChatGPT is a powerful tool. You can ask it to write stories and emails, create recipes(食谱), translate languages, and answer all kinds of questions.
Some schools in the US, Australia and France have banned (禁止) the use of ChatGPT. In the US, for example, New York City public schools banned students and teachers from using ChatGPT on the district’s networks and devices(设备).
The move comes out of worries that the tool could make it easier for students to cheat on assignments. Some also worry that ChatGPT could be used to spread inaccurate (不确定的) information.
“It does not build critical-thinking (批判性思维) and problem-solving skills, which are necessary for academic (学术的) and lifelong success,” said Jenna Lyle, the deputy press secretary of the New York City Department of Education.
Apart from bans, teachers are making changes to their classes to block the use of ChatGPT. Some college teachers in the US try to include more speaking exams and handwritten papers instead of typed ones.
However, not all educators say “no” to ChatGPT. Some Canadian universities are drafting (起草) policies on its use, for both students and teachers. They have no plans to completely ban the tool so far.
Bhaskar Vira, the headmaster at the University of Cambridge in the UK, said that bans on AI software like ChatGPT are not sensible (明智的). “We have to know that [AI] is a tool people will use,” he told Varsity, the school newspaper of the university. What we need to do is “adapt (调整) our learning, teaching and examinations”. That way, we can “have integrity (诚信) while recognizing the use of the tool”.

Success is often considered to be the opposite of failure. To teenagers, it is the achievement of a goal or completion of something they really need, such as good grades and the ability to get along well with their classmates. Some schools used to agree with most parents who measured the success of their children according to grades, but now they pay special attention to moral (道德的) education and character-building to make sure teenagers achieve success in building human relationships.
Schools give chances to students to discover their hidden abilities so that they can enjoy some form of success. For example, those good at speaking skills are advised to take part in speech competitions while those interested in arts are expected to perform in front of their classmates. Teenagers also get the pleasure of success when they join their favorite clubs.
Teenagers are often told that success is not easy to achieve and that success lies in hard work. Great efforts have to be put into project work. Doing things much later than planned should be avoided as this will lead to a mountain of work which finally makes them nervous. Another good quality (品质) is a sense of responsibility which makes them remember that a task has to be completed.
Sticking to moral values is the key to success, too. Honest teenagers will win the trust of friends leading to good relationships. Self-motivation (自我激励) is another quality to be developed, for self-motivated teenagers will have the strong will and drive to perform a task and finally get to enjoy a sense of achievement.
1. What does the underlined word “measured” in Paragraph 1 mean?| A．Answered. | B．Decided. | C．Planned. |
| A．project work makes teenagers nervous |
| B．good qualities will lead to a happy life |
| C．teenagers are advised to complete tasks in time |
| A．Honesty | B．Self-motivation | C．Communication |
