The well-known “new great inventions” of modern China have made our daily lives more convenient.
High-speed trains
China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken on the trains. By 2020, one-fifth of the country's 150,000 km railway network will be used by the trains. This network will link more than 80 percent of major cities across China.
Mobile payment
Mobile payment is turning China into a“cashless society”. Instead of paying by cash (现金),customers now pay for their goods and some kinds of bills simply by typing a short password into the Alipay or WeChat pay app on their mobile phones.
Shared bikes
China has surprised the world with how quickly shared bikes are widely used. Nowadays, bike users can simply pick up or park the bike on the street through GPS and smart phone apps. China's two leading bike-sharing companies, Mobike and Ofo, have been open their overseas markets in Singapore,the UK and the United States.
Online shopping
With around 751 million Internet users, China has been the world's largest and fastest-growing online shopping market. Because of lower costs and fewer licensing requirements (执照要求), it's easier for sellers to open an online shop in China. In 2016, more than 20 million jobs of rural areas were created, with over 8.1 million running their own online shops.

Dog owners now have a little help understanding their funny friends. A new device (装置) called Bow-Lingual (狗吠翻译机) can translate dog barks.
Japanese inventors of the Bow-Lingual device spent much time and money studying dog barks. They have found that dog barks can be broken down into some different feelings: happiness, sadness and frustration (沮丧). Later they have also found dog noises have feelings of anger and desire (愿望).
One part of the Bow-Lingual device hangs on the dog's neck. The other part is a handle-held unit for the owner. When the dog barks, the unit displays translated phrases.
Some people have scoffed at Bow-Lingual. “Who would pay $120 to read a dog's mind ” they ask.
But those who have bought Bow-Lingual praise the device. A pet owner, Keiko Egawa, a Japanese, says it helps her know better about her dog, Harry. “Before we go to the park, he always says he wants to play,” says Egawa. “And after a walk, he always says he is hungry.”
Bow-Lingual is not yet available in China.

When were the cameras invented Let's go into the past. In the 1500s, men made experiments(试验) on cameras that made images. But it was not until the early 1800s that someone found a way to make the pictures permanent (永久的). Then photography was a new technology. Most families couldn't take pictures themselves. They would turn to a photographer. People didn't have their own cameras because it was too difficult to take pictures and develop the film (冲洗胶片).
In 1884, George Eastman invented a kind of film that fitted back to a small camera to change photography and the new film was easy to use for many people, so they began to buy cameras. When they had used up (用完) their films, people sent their cameras back to the factory. The film was developed in the factory and helped print pictures. Then more and more people could use the cameras and film.
Eastman's invention made it easy to take photos. Today's cameras are even easier to use and people can put in films themselves. Taking photo has become a growing hobby.
There are also many new jobs in the field such as newspapers, magazines and televisions. They all need pictures to tell their stories well. With the help of photographers, scientists can take pictures through microscopes (显微镜) and telescopes (望远镜). Deep-sea divers take pictures of ocean plants and animals, while astronauts take their cameras into space.
( ) 9. In 1884, George Eastman changed photography by inventing a new kind of .

(D)
Scientists in Switzerland have used lasers (激光) to change the path of a lightning strike (雷击的路径). The experiment suggests that in the future, lasers might be useful for protecting large buildings from lightning.
Lightning can be extremely powerful and cause serious problems on the ground. Lightning strike can cause fires, destroy buildings, and even kill people. The damage from lightning costs billions of dollars every year. In the US, lightning strikes killed close to 450 people between 2006 and 2021.
Scientists have been trying to find a way to protect buildings from lightning for a long time. Now the best way is by putting metal rods (金属竿) on the buildings. These rods are connected to the ground.The lightning is attracted to the rods, which safely guide the electricity into the ground. But lightning rods can only protect a small area. Some buildings——such as airports are so large that it's difficult to protect the whole building using lightning rods.
Another idea is to use lasers to guide lightning. Scientists had been working on the idea for over 20years. They have successfully guided lightning with lasers inside a lab. But until the summer of 2021,scientists could guide lightning with lasers outside. Using a powerful laser, scientists in Switzerland were able to guide lightning for 50 meters.
The heat from the laser creates a path of air that is less thick than the air around it. The path also has a special charge (电荷). The lightning can follow this path almost as if it were a lightning rod.Scientist Matteo Cleríci said, “The fact that we managed to do it in an outdoor environment is a very big step.”
But the laser still didn't guide the lightning as far as the scientists would like. Besides, the laser is*also very expensive. The scientists say it cost about $2 billion. It will probably take 10 or more years before a laser like this is truly able to protect large buildings.
( ) 13. To know how powerful lightning can be, which paragraph can we read
A. Paragraph 2. B. Paragraph 3. C. Paragraph 4. D. Paragraph 5.
( ) 14. What is the laser technology expected to protect
A. High-rise buildings. B. Large buildings.
C. Beautiful buildings. D. Important buildings.
( ) 15. Why are lasers not used widely for changing the path of lightning strike now
A. Putting metal rods on the buildings is the best way.
B. Some buildings are so large that it's difficult to protect.
C. Lasers are only able to guide lightning for a short distance.
D. Lasers are so expensive that scientists can't pay for experimenting.
( ) 16. What can we get to know at the end of the passage
A. Behind bad luck comes good luck.
B. A journey of a thousand miles begins with a single step.
C. There is still a long way to go before a laser can really work.
D. For scientists, working together is better than working alone.

The FIFA World Cup has come to an end in Qatar and excitement is truly kicking in. It's the world's biggest international soccer tournament ( 比赛) and also the most-watched sport ing event in the world. There are 32 teams competing to win. This year's tournament looks to be particularly (尤其)unique. What makes it different from the ones before
For starters, it's the first time the tournament has been held in the Middle East after Qatar beat other host competitors—the US, South Korea, Japan and Australia back in 2010. It's also the first time in history the tournament is happening during the Northern Hemisphere (北半球) winter months, fromNov 20 to Dec 18.
That's because Qatar is a desert country, and in summer the temperature can be as high as 42℃.That's too hot to play outdoor sports. But it will still be pretty warm in winter. The temperature in the stadium is expected to be around 20 C to 30 C. Air conditioning (空调) will help to keep it cooler.Qatar is also the smallest nation by area to host the cup. They'll be playing the first match of the tournament, facing Ecuador (厄瓜多尔). It's Qatar's first-ever FIFA World Cup game. This makes them the first country to host their debut (首秀) game since Italy in 1934!
There may be new challenges for many players too. Aside from (除……之外) the hot weather,for European teams like England, France, Germany and Spain, it's only just over a year since their last big international tournament, the UEFA Champions League (欧联杯). According to FlFA's rankings(排名), the favorites to win the tournament this year are Brazil, followed by Argentina and France.
41. How many teams are going to compete in the World Cup
42. How long does the 2022 FIFA World Cup last
43. What kind of country is Qatar
44. What's your favorite sport Who is your favorite athlete Why (write 30 words or more)

V. 45. One possible version:
There are many rules in my family. One of them is that I have to go to bed before 10: 00 p. m. I agree with this rule. I think students like me need to get lots of sleep. Then it is easier to concentrate and listen to the teacher in class. I always obey this family rule,but I'm unhappy about another rule in my home. The rule is that I'm not allowed to have a pet dog. My parents are afraid that I will spend too much time on the dog, but I think that a pet dog is just like a good friend. I can talk to it when I'm lonely or unhappy,so I will have a talk with my parents later.
