In the universe, there is the sun, the moon, the earth and many stars. Through our geography lessons, we 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 further, and small things also look bigger when they are nearer.
The sun is big enough to give out very strong light. The moon can’t give 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 actually（事实上）the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are further away from the earth.
There are many other planets in the universe. But of all the planets, only on the earth there are living things and people can only live on the earth, too. But at 9:00 a. m. on October 15th, 2003, Chinese pilot Yang Liwei was sent up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.

【推荐1】What do black holes look like? Human beings have wanted to know about it for a long time. In 2019, we finally got the answer. They look like dark circles with a bright ring around the outside.
Scientists took the world’s first photo of a black hole. Scientists didn’t use a camera to take the picture. They used eight radio telescopes in different places around the world. Telescopes got signals (信号) from the black hole. Scientists used computers to process (处理) the signals. It took them two years to get the final picture.
The black hole is very far from Earth—about 55 million light years away. One light year is the journey that light travels in one year. One light year is about 9 trillion (万亿) kilometers.
This isn’t the only black hole in the universe. In fact, scientists believe every large galaxy (星系) has a big black hole at its center. The one in our galaxy is called Sagittarius A.
Black holes are some of the most mysterious (神秘的) things in the universe. This photo can help us learn more about them.

carry traits, such as being tastier, brighter, and riper? They are genetically engineered.
Genetic engineering（基因工程）is like making a change in a recipe. For example, when you make cakes, you mix together all of the usual ingredients. If you add an extra ingredient, like salt, the cakes will taste differently.
Genes are ingredients in the recipe for life. They carry the traits of living things. Your genes dictate what color hair and eyes you’ll have, how tall you’ll be, as well as many other traits. Genes carry traits for plants, too. By adding genes to a plant, you can sometimes create new traits. For example, adding a certain gene to a potato plant can make the potato plant distasteful to bugs（虫子）. This makes some farmers happy because they don’t have to use chemicals to keep bugs away from their plants.
It sounds great, but some people are opposed to the idea of food that is genetically engineered. Ronnie Cummins, from the Campaign for Food Safety, is against it. He says that one of the major concerns is allergies（过敏）. Supermarkets don’t always label foods that are genetically engineered. A customer could unknowingly buy food that has an added gene from another plant that he or she is allergic to. It could be dangerous.
Gary Burton from Monsanto, a seed（种子）company that engineers food, disagrees. He says his company tests for allergies. Burton believes that genetic engineering is a valuable tool for making better food. The technology can help farmers use less insecticide（杀虫剂）and grow healthier crops. Burton thinks there are many advantages.
But Cummins says that we just don’t know what will happen in the future if we keep adding genes to foods. We could mistakenly create a monster.
People have different opinions about genetic engineering. One side supports it and thinks it will only help us. The other side is opposed to playing with nature and fears health risks. Which side do you think is right?

The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see.Their light had burnt out. Others are still bright, but they are so far away that we can not see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life-giving star.

【推荐3】Garbage sorting is a big issue worldwide. In recent years, some Chinese cities have been working hard on it.
Shanghai has worked with Alipay to create a “green account (账户)” service for its residents (居民). Account holders get points by correctly sorting their garbage. Through the Alipay app, they can exchange the points for milk, phone cards and other products. The city is asking all of its residents to sort their garbage into four groups: wet, recyclable, harmful and dry.
Wet waste is also known as household waste. “They are things you don’t want but that pigs can eat,” Guangzhou Daily explained. Paper, metal (金属), glass and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and fluorescent bulbs (荧光灯泡). Finally, any waste that’s not wet, recyclable or harmful will go in the “dry waste” bin.
Many other Chinese cities are also using this method to sort their garbage. For example, Shenzhen has been sorting its garbage into the same four groups since 2012. Students there also receive waste-sorting guidebooks that they must study.
China is improving its waste-sorting efforts. There is still a long way to go. But it’s never too late to learn how to sort your trash properly and protect the environment.
If you don’t sort your garbage, all of it will go to a landfill (垃圾填埋场) and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of garbage, like the metal part of a pen, can be used to make other things if they are properly recycled.
1. How is Shanghai encouraging people to sort their garbage?| A．Paying people to sort their trash correctly. |
| B．Creating a “green account” servịce with the help of Alipay. |
| C．Providing its residents with guidebooks to help them. |

【推荐1】Hot pot is very popular no matter in hot summer or cold winter in China. It has a history over 1,000 years and until now, it is still the most popular dish for social or family gathering. People put a metal pot in the middle of a dining table, and while the water in the pot is boiling (沸腾) , ingredients are put into it and cooked in the pot. They are usually thinly sliced beef, pork, chicken, lamb, leaf vegetables, tofu and seafood. Many Chinese people like eating hot pot. Liu Yang is one of them.
Liu Yang went to university in England. Three days ago, he arrived there. He had three days of hamburgers, sandwiches and potatoes. Yesterday he was very excited when he heard that there was going to be a meal of hotpot to welcome the new students.
He went into the room and sat next to an American girl. To his surprise, he saw potatoes and bread in front of him. Where was the hot pot?
When the American girl found that Liu Yang was very surprised, she made an introduction to him that hotpot is not hot pot. China has hot pot in two words but English hotpot is written in one word. Hotpot is made with meat, potatoes and onions. People put them into the oven all day in a heavy pot and over a low heat. It is easy to cook.
Hotpot tastes fine. But Liu Yang still misses hot pot, two words!

【推荐2】Work is helpful to health. Scientists find that the hard-working people live longer than those who have no jobs. Studies show that the jobless are in poorer health than job-holders. The women who have jobs are healthier than housewives.
Why is work good for health? It is because work keeps people busy away from feeling lonely. Researches show that people feel unhappy and worried when they have nothing to do. The happiest people are those who are busy. Many high achievers who love their jobs feel they are the happiest when they are working hard. They work as a bridge between their dream and reality, so they have energy everyday. By work, people get to know each other. By taking part in all kinds of activities, they find friendship and warmth. This is helpful to health. The loss(丧失)of work means the loss of everything. It makes people down and it will cause more illnesses.
Besides, work makes one feel hopeful and proud. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are very happy.
From the above, we can come to a conclusion: the more you work, the happier and healthier you will be.
1. People who have no jobs are ________ than job-holders.| A．in poorer health | B．happier | C．healthier | D．busier |

【推荐3】①Researchers have long tried to understand the advantages of watching birds. A study in Scientific Reports last October in 2022, found that seeing or hearing these birds improved people’s feelings of happiness for up to eight hours. And a study in 2020 showed human’s happiness even has something to do with the number of different bird kinds around people’s homes and towns. Another research in 2017 supported the idea that birds are good for human’s brain. All the researches above show that birdwatching is good for mental (心理的) health.
②Why can birds make such a great difference? A very simple reason is the fact that birds can fly. And it is really fascinating. Another reason could be that spending time with flying birds in nature improves mental health, a mental health researcher at King’s College London once said.
③It may surprise you that birdwatching can make people less stressed out. Siting outside and listening to the birds, and getting to know their songs, can really keep you calm. Seeing birds flying can make you full of imagination. And it can let your worries fly away.
④When people search for a safe and free outdoor activity to relax, birdwatching is a good choice. A great thing about birdwatching is that anyone can do it. Here is how to start.
⑤One of the simplest ways to start is by feeding the birds. If you don’t know the names of the birds you see, you can use an app called The Cornell Lab’s free Merlin Bird ID to get to know them by the sounds they make.
⑥For another, if your family has a backyard, do what you can to make it a nice place for birds. One way is by choosing proper plants that attract (吸引) and protect them. The National Audubon Society can help you to know the proper plants. The last simple thing you should know about birds is that “All birds get thirsty”.
