1 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.
Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.
There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”
Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.
A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.

2 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.
The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.
“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.
Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

3 . A year back I received a full scholarship to attend the University of San Francisco. All of my hard work had paid off. My mom had spent a lot in my attending a private high school, so I made sure to push myself: I volunteered, joined different clubs, and graduated with honors.
I was so excited to start a new life. I had totally packed two weeks and wanted to go to college at once before it was time to leave.
Soon enough, the big day came, but it wasn’t like what I had thought. The first two weeks were the most difficult days of my entire life. Every night I would cry myself to sleep.
I was so homesick (想家) and I didn’t know how to deal with my broken heart. To distract myself, I threw myself into my studies and I applied for a lot of jobs. In any remaining free time, I started forcing myself to the gym. I wanted to keep every part of my day busy so I wouldn’t think how lonely I felt.
Soon after, I began to limit food, and then I became worse. Finally, I went to see a doctor. When the doctor weighed me, I was crazy about the number of my weight. So I continued to lower my goal, and convinced that controlling this number was the solution to my homesickness. But when I was told that I had no choice but to spend time on my studies. I quickly started recovery in my mind.
How could I do? I told myself that school was what I was best at. I decided to get rid of my homesickness and took exercise actively. My first term of college had passed by at last and I had gotten straight A’s. That’s why I want to share my story—to help other students feel less lonely.

4 . In 2011, artist Grimanesa Amorós stepped off a boat made of totora reeds (芦苇) onto an island—also made of totora reeds — in the northwest portion of Lake Titicaca. It’s home to one of the world’s most innovative achievement of human engineering: the Uros Islands.
The man-made floating islands, which are home to the native Uros people, are created by putting layers upon layers of totora roots and reeds. This water-resistant plant grows in the lake and is the lifeblood of the Uros community. It is used to make boats, houses, roofs, mattresses (床垫) and more. The plant is also eaten and serves as medicine, and its flowers are used to make tea.
However, the Uros weren’t always dependent on the totora. More than 500 years ago, the growing Inca Empire began to invade the Uros’ mainland villages. To beat this threat, the Uros began to build the islands, which could be launched deep into Lake Titicaca, away from danger. Hundreds of years later, there are now about 120 of these constructed islands, with around 1,300 people living on them.
To build the islands, the Uros first gather large blocks of totora roots. Multiple blocks are pulled together, and the roots and reeds mix naturally to form a layer about 1 to 2m thick. The totora reed is laid on top of this floating base. The Uros use a long tool to reach deep down into the water and cut the plant above the base. Then, the reeds are dried in the sun for one to four weeks and bundled (捆绑) together using a rope. Once dried, totora reeds are placed in alternating directions on top of the root blocks and become the ground that the Uros walk and build their homes on.
Today, urban influences are evident on the islands: Solar panels power bedroom lights and small TVs; a radio station operates on the main island. It’s evident that these modern changes and tourism have changed the Uros’ life on the lake. One thing remains certain, though. As long as there is totora growing at Lake Titicaca, the islands’ rooted foundation will stay the same.
1. Which word can best describe the role totora reeds play in the Uro’s life?| A．Essential. | B．Symbolic. | C．Protective. | D．Sustainable. |
| A．To develop tourism. | B．To maintain their lifestyle. |

5 . People generally like to pick out the best-looking fruits and vegetables when shopping for produce (农产品), but Canadian supermarket chain Loblaws is attracting customers with badly-shaped and faulty produce at the price of 30% lower than normal-looking one.
A trial run of the ugly food line, named “Naturally Imperfect”, began with only apples and potatoes to choose from. Consumer demand has been so huge that Loblaws is going to introduce more ugly vegetables and fruits like onions and mushrooms.
All the produce that will be sold through Naturally Imperfect would otherwise have been used in juices, sauces, or soups, or have not been harvested at all. The director Dan Branson explained that this program benefited both food producers who would otherwise have to let abnormal produce go to waste, and consumers who could buy fresh produce at low prices. And he was right, given how popular the line has become.
“It really went well beyond our expectation,” Branson said. “I think it really spoke to the fact that Canadians are out there really looking for some options.”
Of course, Canadians know that beauty is more than skin deep, and they also recognize that they can get the same flavor and nutritional benefits in spite of appearances. The positive response to the initial offering of apples and potatoes showed the opportunity to expand the line and offer more options at a greater price to Canadian families.
“If you grow produce in your backyard, there will be a lot of produce that won’t look as pretty as what you will see in a grocery store”, said Branson. “And nature doesn’t grow everything perfectly. I’d like to think if somebody were to take a No Name Naturally Imperfect apple, put it right beside a No.1 apple, close his eyes and eat them, there would be no difference.”
1. Loblaws is different from other supermarkets in that ______.| A．more fruits are offered at lower prices | B．normal-looking produce is forbidden there |
| C．only apples and potatoes are sold every day | D．imperfect produce is sold at lower prices there |
| A．prevents people from wasting their food | B．happens to be a win-win mode |
| C．teaches food producers how to grow | D．enables consumers to eat more fresh produce |
| A．Canadians are used to eating perfect produce. |
| B．Smart consumers know the importance of ugly produce. |
| C．Loblaws intends to improve customers’ quality of life. |
| D．Customers’ support promotes the development of the ugly food line. |
| A．Imperfect fruits are as tasty and nutritious as perfect ones. |
| B．The world is usually full of imperfect things. |
| C．We should eat imperfect apples with our eyes closed. |
| D．The fruits grown by ourselves are more nutritious than those in the store. |
6 . The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language and connect with family and friends.
As far as the Internet being a part of our lives —well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers.
A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group— teenagers. The study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure. High blood pressure can cause heart and kidney (肾) disease. It is also closely linked to some forms of dementia (痴呆), a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people from 14 to 17 years old participated in it. One hundred and thirty-four of the teens were described as “heavy Internet users.” Researchers found that out of these 134 teens, 26 had high blood pressure.
The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldn’t consume us.” For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week.” Ms. Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity.”
1. Which of the following statements is closest in the meaning to the underlined sentence in Paragraph 2?| A．The train has stopped at the wrong station. |
| B．There is something wrong with the train. |
| C．Life without the Internet is nowhere to be found. |
| D．The train has changed its course. |
| A．will remember everything clearly | B．will change his character |
| C．will develop a brain cancer | D．can do analysis accurately |
| A．40% | B．19% | C．25% | D．7% |
| A．The Internet Does Harm to the Study. |
| B．Too Much Internet May Be Bad for Teenagers. |
| C．We Should Stop Using the Internet. |
| D．High Blood Pressure Is around the Comer. |

8 . Are you a fan of outdoor adventures? Do you enjoy scenic views to relax? Look no further, as the following destinations offer all that and more.
Athabasca Falls
Alberta, Canada
Water from the Canadian Rockies flows down into the waterfalls of Jasper National Park, creating a flow with wild energy. The falls are wheelchairs accessible, with a paved path taking admirers to a number of viewpoints. If visitors leave the path, they can explore both the upper and lower regions of the trail.
Akaka Falls Trail
Hakalau, Hawaii
A short half-mile hike is big on sights and low on hard activity. The well-kept ring like trail guide visitors around to see a number of waterfalls, including the 442-foot main attraction, and beautiful local flora (植物群) among the famous landscape. Though there are no hills to climb, there are a number of stairways to go.
Nugget Falls
Juneau, Alaska
Located in Tongass National Forest about 12 miles from Juneau, the Mendenhall Glacier has produced Nugget Falls, a fan-like waterfall that leads into a lake. A series of short hikes allows for different views of the waterfall and icy surrounds, which are also known for frequent brown bear sightings.
Yosemite Falls
Yosemite Valley, California
Yosemite National Park is one of the oldest national parks in America and home to the fifth tallest waterfall in the world. Hikers can reach it by taking a 1-mile trail from the lodge or the 7.2-mile round-trip Yosemite Falls Trail route. Late spring is best, with the highest water flow. In the winter, the temperatures dip below freezing. A park admission fee applies.

9 . What is language for? Some people seem to think it’s for practicing grammar rules and learning lists of words — the longer the lists, the better. That’s wrong. Language is for the exchange of ideas and information. It’s meaningless knowing all about a language if you can’t use it freely. Many students I have met know hundreds of grammar rules, but they can’t speak correctly or fluently. They are afraid of making mistakes. One shouldn’t be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too. Bernard Shaw once wrote, “Foreigners often speak English too correctly.” But the mistakes that native speakers make are different from those that Chinese students make. They’re English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, they make language. But a people can only make its own language. It can’t make another people’s language. So Chinese students of English should pay attention to grammar, but they shouldn’t overdo (做过头) it. They should put communication first.
1. According to the passage, language is used to ________.| A．express oneself | B．practice grammar rules |
| C．talk with foreigners only | D．learn lists of words |
| A．never makes mistakes | B．often makes mistakes |
| C．can’t avoid making mistakes | D．always makes mistakes |

10 . Most of us know something about the Nobel Prizes, especially the Nobel Peace Prize, but few of us know anything about the man who set them up. His name was Alfred Nobel. He was a great scientist and inventor himself. Besides, he had a big business. His business may surprise you. He made and sold explosives (炸药). His companies even made and sold weapons (武器). Isn’t this something that surprises you? The man who made money from weapons should set up the Nobel Peace Prize?
Though Alfred Nobel had a lot of money from weapons, he hated war. He hoped that there would be no war in the world. He was one of the richest in Europe. When he died in 1896, he left behind him a lot of money and his famous will (遗嘱). According to his will, most of his money was placed in a fund. He wanted the interest from the fund to be used as prizes every year. We know them as the Nobel Prizes. The Nobel Prizes are international. Alfred Nobel wanted the winners to be chosen for their work, not the country they came from.
Alfred Nobel had given his whole life to his studies and work and to the benefits of mankind. He made money all by his own efforts, but he left the world share his wealth. His inventions and wealth stay with the world forever.
