But not everyone knows why. Kids News researched the Dead Sea and found some interesting facts.The Dead Sea is an inland lake 50 kilometers long by 15 kilometers wide in the Middle East between the west bank and Jordan. The Jordan River is the main source of the Dead Sea water. It is about 430 meters below sea level, the lowest point on the surface of the Earth. The water level has been dropping even lower for the past 60 or so years. It drops about 1 meter each year.It’s a popular place for people to have a holiday, partly because it’s in the desert, which means lots of hot, sunny days.It’s called the Dead Sea because it is full of salt. The Dead Sea water is perhaps 10 times as salty as open ocean seawater and nothing much can live in it. Exactly how sally it is changes through the depth (深度) of the lake and with how much water is flowing in (流入) from the Jordan River and how much water is evaporating (蒸发). The water of the Dead Sea is full of salt, which makes it much denser (密度更大) and heavier than freshwater. If you swim in it, you float (漂浮) very easily.6. Which of the following is right?A.

Qomolangma is very famous and it is higher than any other mountain in the world. Its newest height is 8, 848.86 meters, which was announced on December 8th, 2020. At the height of 8, 000 meters, there is only 30% O2 and the human body can only stand this height for a few days, so it is dangerous for humans to climb higher. But many climbers want to challenge themselves in the face of difficulties. As Alan Arnette, a mountain climber from America, said “Climbing mountains drives you to look deep inside yourself, and lets you find out whether you are healthy enough and strong enough in mind when you want to stop.”It’s a good thing that Qomolangma gives people a chance to become strong-willed(意志坚强的) when trying to achieve their dreams. ▲ because many people leave their waste behind, such as water bottles and plastic bags. They cause the environmental pollution for Qomolangma. Many local farmers said their sheep and cows would die after eating the plastic bags and it was too difficult to clean them up. Luckily, many volunteers from all over the world came to Qomolangma to join in the clean-up activity. A volunteer advised, “When climbing Qomolangma, mountain climbing lovers should always take good care of themselves, and at the same time, take good care of Qomolangma.”9.

This man-made waterway—known in China as Da Yun he — is 1,700 kilometers long and some parts of it are more than 2,000 years old. It links the north of China with Hangzhou, a city in the southern part of the country. It’s the longest man-made waterway in the world. It was built as a way to transport grain（谷物）from the rich agricultural land in China’s south to cities in the north. In fact, it’s not one canal, but a system of canals and rivers linked together. It’s still an important part of the transport system in China. Thousands of boats use it every day to transport grain and many other types of cargo. Now the Chinese government is doing new work on the Grand Canal. It is making parts of it deeper, so bigger ships can use it. The canal will also help to move water. There is a lot of rain in the south of China, but not as much in the north. The canal will carry millions of liters of water from the south to the north. The Grand Canal is much less famous than the Great Wall, and not very many tourists visit it. But it’s possible to go on a cruise （乘船游览）along some of the oldest parts of the canal.

The well-known story of Pinocchio teaches the importance of telling the truth. Every time Pinocchio lies, his nose grows longer and longer. Another story is about the boy who “cried wolf.” In the end, he loses all his sheep and the trust of his fellow villagers because he tells lies many times. These types of stories show children that “honesty is the best policy.” Still, if this is the case, then why do so many people lie? The fact is that people lie for many reasons. One reason people lie is to minimize(减少) a mistake. While it is true that everyone does something wrong from time to time, some people do not have the courage to admit their errors(错误) because they are afraid they will be blamed. For example, students might lie to their teachers about unfinished homework. They might say that they left the work at home when, in fact, they did not do the work at all. These students do not want to get in trouble or seem irresponsible, so they make up an excuse—a lie—to save face. Another reason for lying has to do with self-protection. Parents, particularly those with young children, may teach their children to use this type of “protective” lie in certain circumstances (状况). What should children do if a stranger calls while the parents are out? Many parents teach their children to explain that their mother and father are too busy to come to the phone at that time. In this situation, protective lying can mean greater safety. People lie for many reasons, both good and bad. Lying to keep the peace or to stay safe can have positive results. However, lying to stay out of trouble can lead to more trouble in the end. Understanding the motives behind the impulse (冲动)to lie might minimize this habit of lying.26. What does the underlined word “this” refer to in the passage?A. Honesty is the best policy. B. The well-known story of Pinocchio. C. The story of the boy who "cried wolf".27. How does the writer explain why people tell lies?A. By asking questions. B. By giving examples. C. By showing the results.28. What is the correct structure of the passage?（P=paragraph 1. ） A. B. C. 29. What’s the best title for the passage? ________A. The Types of Lies. B. The Habit of Lying. C. The Truth behind Lying.8（2021·四川资阳）If you think of the jobs robots could never do, doctors and teachers may be your answers. It’s easy to imagine smart cleaners and robot factory workers, but some jobs really need human thinking and creativity（创造力）. Nowadays, robots already do a better job than doctors in hospitals in some way. Could there be a place for robots in education?British expert Anthony Seldon thinks so. He believes in 2027 robots will do the main job of passing information and teachers will just help. They can even read students’ faces, movements and brain activities. However, it’s not a popular idea and it’s impossible that robots will really connect with humans like another human can. But one thing is certain. A robot teacher is better than no teacher at all. In some parts of the world, there aren’t enough teachers. That problem could be partly solved by robots because they can teach anywhere and won’t get tired or move somewhere for a better job. Perhaps the question is not “Can robots do everything instead of teachers?” but “How can robots help teachers?” If robots could help to save the time teachers spend on students’ homework and reports, teachers would have more time and energy（精力）for the parts of the job humans do best.30. Anthony believes in 2027________.A. robots can do a better job than doctorsB. robots will do the same job as human teachersC. robots can understand students from their facesD. robots will move for better jobs like human teachers31. Why could robots partly solve the problem in Paragraph 3? ________A. They can teach anywhere. B. They can’t get tired easily.C. They can’t waste time on homework. D. They can do everything instead of humans.32. What does the writer think of robots in education? ________A. Thankful. B. Smart. C. Popular. D. Helpful.33. What is the best title for the passage? ________A. Robot Doctors. B. Robot Teachers. C. Abilities of Robots. D. Jobs of Robots.9（2021·四川雅安）We all know the dangers of fires.

Many young people pick up the habit every year—in fact, 90% of all adult smokers started when they were kids.You might wonder why people smoke at all. Many people start smoking when they are kids or teens and they try it for many reasons. Maybe all of their friends were doing it or they grew up in a house where all the adults smoked. On the other hand, kids started smoking in order to look cool, act older, lose weight, or feel independent.But no matter why they started, many smokers（ men, women, boys or girls）wish they could stop. Stopping smoking is hard, though, because there is nicotine （尼古丁） in cigarettes （烟）. Someone can get addicted to（沉溺于） nicotine within days of first using it. When something is addictive, your body and mind will tell you that you need it to feel OK. If you don’t get it, you might feel sick, stressed out, or get angry.Stopping smoking mostly has two steps. The first step is to deal with your dependence on nicotine and the other is to break the habit of smoking. When you stop smoking, you may have to wait a few days or even weeks before the nicotine finally leaves your body.Most importantly, we must make sure kids and teens understand the dangers of smoking as early as possible.39.

Local people not only sort their rubbish, but also put QR codes (二维码) on it.“When the rubbish is collected and the codes are seen, I will get reward points to exchange for small gifts and even some money,” one of the local people told reporters. “It’s really creative and encouraging.”This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example, Shenzhen and Shanghai have made laws to punish sorting rubbish incorrectly.China produces quite a lot of rubbish every year. Much of the rubbish is buried (填埋) in soil or burned without being sorted. Landfills (填埋场) take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting, we can reduce the use of landfills and air pollution.What’s more, rubbish sorting saves resources, which could bring economic benefits (经济利益). For example, a ton of waste paper can be reused to make about 850 kg of paper, saving 17 trees and 50 percent of water. Because of their benefits, some countries have developed successful sorting systems.Japan has a strict and detailed system. When people throw away a water bottle, the cap, the wrapper (包装纸) and the bottle itself have to go into three different bins. Every year, families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish.In Australia, every family is provided with three rubbish bins — the red lid (盖子) bin for “general waste” like food and plastic bags, the yellow lid bin for “recycling” like steel and glass, and the green lid bin for “green waste” such as grass and leaves. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.43. What will local people probably get if they put daily rubbish into the new system in Fangchengyuan Community?A. A computer. B. A car. C. A lot of money. D. Some small gifts.44. Which of the following is NOT the consequence (后果) of burying rubbish?A. Polluting soil. B. Polluting water.C. Taking up a lot of land. D. Saving resources.45. Which paragraph discusses the economic benefits of rubbish sorting?A. Paragraph 3. B. Paragraph 4.C. Paragraph 5. D. Paragraph 6.46. In Australia, which bin should you put food left after dinner in?A. The red lid bin. B. The yellow lid bin.C. The green lid bin. D. The black lid bin.47. Which of the following is TRUE according to the text?A. In Australia, the green lid bin is used for all kinds of recyclable (可回收的) wastes.B. In Japan, all kinds of things for recycling are printed on rubbish bins.C. Japanese people cannot throw a bottle into a bin unless they move away the wrapper first.D. Australian people have to obey local timetables and directions to throw away rubbish strictly.12（2017·辽宁丹东）Stamps (邮票) help people keep in touch with their friends and families. They have played an important role in people’s lives for centuries now.

In the past ,people used paste(糨糊) sometimes, but usually they had to pin (钉住) or sew (缝) stamps onto letters!        Years ago sending letters used to be the most important way to communicate with other people. It seemed that everyone had stamps on hand. Although now fewer people send letters, stamp collecting is still one of the world's most popular hobbies. There are even stamp clubs to help people find new stamps to add to their collections.

China’s first homemade aircraft carrier (航空母舰) hit the water in Dalian, Liaoning. The new big ship is China’s second aircraft carrier. It was designed in China and built in China, too. It is about 315 meters long and 75 meters wide. That is a bit larger than three soccer fields. An aircraft carrier is like an airport on the sea. It can carry planes and troops to war. Planes fly from and land back on it, and soldiers work and live on it, too. But building an aircraft carrier is very hard and expensive. It costs a lot of money and needs a large amount of steel and other special materials. For example, a basic aircraft carrier is made of 60,000 tons of steel. It also uses complex (综合的) technologies, including radar, electrics, mechanics and weapons. Finally, it takes years to build. Today, not many countries own an aircraft carrier or have the ability to build one. China has become the seventh country in the world that can build an aircraft carrier by itself, after the USA, Russia, England, France, Italy and Spain.53.

It was big news for students at Beijing Bayi School. After all, they designed the satellite.With the help of space scientists, more than 30 students built this satellite (12 cm long, 11 cm wide and 27 cm tall). This is the first satellite designed and built by middle school students in China.This August, the school worked with the China Center for Aerospace Science and Technology International Communications(CCASTIC 中国航天科技国际交流中心) and started the satellite program. It allowed space experts to teach students about basic knowledge of satellites.After several months of hard work, students designed their own satellite. Their main achievement was the design of the satellite’s functions (功能) in space. “We worked together and came up with more than 10 ideas. But after tests and experiments, we settled on four,” Zhu Xun, 16, told Beijing Evening News.Indeed, they have to consider the weight of the satellite. The satellite will stay in space more than 180 days. Its functions include taking pictures of Earth, radio communication and sending information to Earth. The students hope that the satellite can take photos of smog, typhoons(台风) and other weather conditions.The students were divided into five groups.
