1 . Looking at art should be like walking in the countryside. You may not know exactly where you are, what bird is making that strange sound, or what the hill ahead of you is called, but that’s part of the fun of it. You don’t need to know these things to feel the beauty of nature.
Of course, if you do know your birds, trees and local history, a walk can be more attractive. Yet such knowledge comes slowly. It is picked up through experience. A true knowledge of nature cannot just be given to you through an app on your phone. Imagine pointing your phone at the hill and getting plenty of information on screen. Would that enrich your dreamy walk or ruin(毁灭) it?
Braggarts enjoy an app that allows them to show off their knowledge, for example, about baroque(巴洛克风格的) paintings. In fact, apps in museums try to provide on-screen art history at once just to encourage people to read their phones instead of looking at paintings.
It is a mistaken idea that you need to be spoon-fed(灌输) amazing facts about a work of art in order to appreciate(欣赏) it. Our first experience of a work of art should be raw(自然状态的), unguided, and a bit puzzling, like following a path in the woods. Later, you might choose to do some personal research into the work. It can further increase your enjoyment and appreciation for it. Yet it is best done when you’re away from the art itself, so that even when you return, the work still feels fresh.
Anyone who thinks knowing some dates and details makes you better understand a work of art is wrong. We all need to put aside our screens and our supposed knowledge when we look at art. Let the paintings flow in; let your intuitions(直觉) fly off. Art is a journey in the wilderness or it is nothing at all.

2 . Influenza, or flu(流感), is a type of virus. It spreads from one person to another quickly. When someone who has the flu coughs or sneezes, little droplets from their lungs (肺) spread out into the air. Anyone nearby can get sick. Even a person who touches something with the virus and then touches his or her mouth, eyes, or nose, can become infected(感染).
The outbreak of the 1918 influenza infected about 500 million people worldwide. It killed from 20 million to 50 million people. It was first seen in Europe, the United States, and parts of Asia. It then spread quickly around the world. Many people who became sick were young, healthy adults. At the time, no treatments worked in the prevention of the spread of the killer flu. People were ordered to wear masks. Schools, theaters and other public places were closed.
When the first wave(波〉in the spring of 1918 hit, it didn't seem serious. People who were infected felt the usual flu symptoms(症状), which are chills, fevers, and feeling tired. Those who got sick generally got better after several days. Not many died. However, a second, highly contagious(传染的)wave of influenza appeared in the fall of that same year. Victims died shortly after they were infected — within hours or days. Their skin turned blue and their lungs were filled with liquid(液体), making it very difficult to breathe.
By the summer of 1919, the flu pandemic(大流行病) came to an end. Sick people had either got well or died. Almost 90 years later, in 2008, researchers announced they’d discovered why the 1918 flu was so deadly. The flu virus inflamed (使…恶化)the lungs, causing them to fill with liquid.
Since 1918, there have been several other influenza pandemics, although none has been quite as deadly.

3 . Taking online classes is becoming increasingly popular. Do you know what students around the world think of it? There are four students from different countries discussing it.
Li Mei from Wuhan
Taking online courses gives me a lot more choices and freedom. We can choose to learn whatever we want. Also, online classes make us to study whenever and wherever we want.
Jenny from New York
There are many temptations(诱惑) on the Internet. Students can be distracted easily when they are having online courses. The learning process is not as organized as it is in the classroom.
Reiyu from Tokyo
We might feel more focused on learning when we are having online courses, because we are alone in front of a computer with no one to distract us. In addition, taking online courses also helps us practise our computer skills.

4 . The Taojinshan Greenway (绿道) in Shenzhen has been open to citizens since July, 2019.Sitting at the west side of Shenzhen Reservoir, it is as long as 7.07 kilometers.
With plants along both sides and lakes lying at different sites, tourists can enjoy wonderful scenery all the way. If they are tired, they are free to take a rest at the 3 stops that were built for breaks. Additionally, five unused guard posts (岗亭) along the old route have remained. They serve as sightseeing platforms for visitors to feel the cultural spirit behind the place.
Of all its 13 scenic spots, 8 were designed to have AI helpers. From them, visitors can gain information on parking, tour guide services and more. The smart greenway, with free Wi-Fi available, also provides environmental date, such as temperature, wind speed and air quality. What's more, it can give visitors warnings of coming extreme ( 极端的) weather and natural disasters, including rainstorms and typhoons that may hit Shenzhen.
"Started in the middle of 2015,the building process of the Taojinshan Greenway has taken good care of the wildlife and environment nearby" said Yang Shiming, an official in charge of the project.
The greenway is an example of construction projects without doing harm to the nature. It also shows the role that technology plays in building a smart greenway for more life convenience."

5 . Tea is an important part of Chinese tradition. Tea has very close relationship to Chinese culture.
It's said that Chinese tea was discovered by King Shen Nong. People say that he lived 5,000 years ago. One summer day, while he was visiting a faraway part of his country, he felt very thirsty. When the servants were boiling the water for him to drink, the dried leaves from a near plant fell into the water. The King drank some, and found it could make him feel less tired, which made Shen Nong interested in the new drink. And so, tea was created in 2737BC.
Drinking tea has many advantages. It makes people feel less tired, clears heat inside the human body and helps people lose weight. As you add a cup of tea to your daily life, please check the following advice.
(1)Drink it hot. Tea oxides(氧化)quickly, so it is suggested that you drink it hot.
(2)Do not drink too much strong tea. It will probably be harmful to your stomach and make you feel sick if you make the tea too strong.
(3)The best time to drink tea is between meals. It may not make you have a strong wish to eat when your stomach is full.
(4)Do not drink with medicine. It may change the medical result. You can drink tea two hours after you take medicine.
(5)Green tea is the best choice for office workers. Why? Because green tea helps stop the bad result of the computer.

6 . Elsie Eiler is the head of Monowi, a tiny town in northern Nebraska, U.S.A., and that isn’t her only job. She is also the town secretary, the town treasurer, the librarian, and she works in the café. Why has she got a lot of different jobs? Because there’s nobody else to do them. Monowi has got a population of one — Elsie.
Monowi is an unusual sight. There are about twelve old wooden houses there. They are all empty and are surrounded by a few trees, several old cars and lots of rubbish. The town is silent. An old yellow school bus, with no wheels or seats, stands next to the small school. The school closed 40 years ago. Opposite Elsie’s café is an old building, filled with rubbish. It was a shop but it closed in the 1950s.
The busiest time for Monowi was in the 1930s. Then, the population was 150, and was made up of mostly farmers and their families. There was a railway too. However, the farmers couldn’t compete（竞争）with the large industrialized（工业化的）farms, and left the town to look for other work. In 1971, the railway closed and the town began to die. Three years ago, the last people that lived there, except Elsie’s family, moved away. Then, Elsie’s husband died, and then her son and daughter left to find work in bigger towns, leaving Elsie the only person in the town.
____________Her food is good, her beer is cold, and farmers and truck drivers travel a long way to eat at her café. “One day Monowi will just be memories, and it will probably turn to dust,” she says. “But I like it, and as long as I can take care of myself, I will stay here.”

7 . A tornado（龙卷风）is a kind of strong storm with air which moves in a circle quickly. They can move over 200 miles per hour and cause a lot of damage（损坏）. As they move across the land, they can easily pick up cars, trucks, and even houses, and then throw them very far. It is important to find a safe place if a tornado gets close.
A safe place could be a basement（地下室）or the lowest floor. If you are in a home without a basement, try to find a first-floor bathroom or a small room without windows in the middle of your house. You should curl up（蜷缩）into a ball and cover your head and neck with your hands.
But there are some people who actually want to get close to tornadoes. They are scientists who want to learn more about tornadoes. One of the best ways to do this is to get as close as possible to the tornado. They use special tools to measure （测量） what is happening in and around a tornado.
One special tool is called a tornado probe（探测仪）. Inside the tornado probe, there are sensors（传感器）to measure wind speed, temperature, pressure, and direction. Some probes even have cameras, so the scientists can see and understand what it’s like to be in a tornado.
To be able to get these measurements, the scientists have to get a tornado probe near or into a tornado. Scientists will try to guess where a tornado will go next. Then they drive to that location and put down the probe. If they do not guess correctly, they pick up their probe and try another place. If they are right, the tornado will go near or even right over the probe. Then they take all of the measurements from the probe and use them to predict where future tornadoes may form（形成）and travel. And they can give people some warning to keep away from a dangerous tornado.

8 . It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.
First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain（劳损）, headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.
Second, screen use can do harm to children’s brains. A new study shows that using screens too much can affect（影响） how children’s brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.
Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the ages of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then it’s hard for you to get enough sleep. So you’d better turn off smartphones, TVs, and all other screens an hour before your bedtime.
To keep healthy, doctors and researchers strongly advise that you shouldn’t use screens for long hours.
1. The blue light from your screens can cause ________.| A．eyestrain | B．headaches | C．dry eyes | D．all of the above |
| A．take a break every 15 minutes | B．have lower levels of white matter |
| C．use screens too much before bed | D．are the people from 13 to 64 |
| A．Using smartphones for long hours does harm to your eyes. |
| B．A lot of screen time affects children’s brain growth. |
| C．The light from electronics at night may make you excited. |
| D．People of all ages mustn’t use electronics. |

| C．The ways to use screens. | D．The advantages of using screens. |
9 . Have you ever paid for educational podcasts (播客)or live videos? Ask some people and most of them will say yes. "Pay-for-knowledge" has been more and more fashionable these years. The contents of these "pay-for-knowledge" products are from language learning to gardening or baby-caring. Everything you think of can be found online at this moment. "Pay-for-knowledge" is on the rise(兴起).
Why is "pay-for-knowledge" industry developing so rapidly? First, its development is based on the Internet. With a fast network and a smartphone, anyone who has passed the identity(身份) check can be an online teacher, and anyone with an online account can buy "pay-for-knowledge" products that he or she wants at an affordable price. Second, people are afraid to miss any information. On one hand, people hope for more useful information.
On the other hand, such information is usually at the hands of experts (专家) who serve well-known companies and universities. Moreover, the need to learn new skills in today's job market also pushes people to learn on such educational podcasts.
The industry of "pay-for-knowledge" has proved to be lucrative. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What's more, this is a reflection(反映)of respect for knowledge and talents.
However, the rapid development of "pay-for-knowledge" has a few problems. For one thing, the market is full of eye-catching words such as "How to be an Industry's Expert in 5 Hours" and "15 Classes to Be a Master of Appreciating (欣赏) Classical Music", which sound like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. In fact, those who have really had self-growth after buying online courses may be the kind of people who need them least. In other words, with or without these courses, they can make it anyway, because they are those who have the ability to learn by themselves.
In general, the best is the one that suits you most. "Pay-for-knowledge" may be used as a good start for self-growth. Be careful! Otherwise, your dream of success may not come true.
1. Which of the following is TRUE according to the passage?| A．"Pay-for-knowledge" products can help all the people succeed. |
| B．"Pay-for-knowledge" products can offer people different kinds of courses. |
| C．People who can teach themselves need "pay-for-knowledge" products most. |
| D．People must learn from experts who serve famous companies and universities. |
| A．The history of its development. | B．The problems of its products. |
| C．The advantages of its products. | D．The causes of its rise. |

| C．win great respect | D．enjoy self-growth |
| A．recommend the "pay-for-knowledge" products to people |
| B．advise everyone to learn knowledge by themselves online |
| C．remind people to choose "pay-for-knowledge" products wisely |
| D．teach parents how to buy some online courses for their children |
10 . “Amy! Milk!” Mama called.
Milk. It was Amy’s turn to get it. Amy sighed and shut her first-aid(急救) book.
Amy tied the cow close to a tree. Somewhere down the mountain, some volunteer doctors were teaching medical skills to village nurses. Amy heard Betty dive off hours ago. “She should have taken me with her. She thinks I’m too young.” Amy thought. “But she’s wrong. I am already 15!”
Amy carried the milk back to Mama, then wandered up the road. Roy, a village boy, was trying to stand on a horse’s back. “No wonder they don’t trust kids with anything important,” Amy thought.
She had just turned away when she heard a heavy fall and a few cries. Roy was on the ground. “Roy!” The kids nearby ran towards him. “Get Betty,” one said. Amy shook her head. “Betty’s gone to the city.”
The kids didn’t know what to do. Amy ran to Roy and saw one of his legs out of shape. A broken leg! She remembered what the first-aid book said about it.
“Victor!” Amy called to one of the boys. “Go get Roy’s mama, and find someone with a truck,” She turned to the others. “Give me your shirts. We need something to tie his leg with.”
Amy then found a strong, straight stick. She carefully wrapped the shirts around Roy’s leg and the stick. Roy cried out in pain. “I know it hurts,” Amy said softly. “But this will hold it still until you get to the hospital.”
When Amy was done, she looked up and saw Roy’s mama and a man watching beside a truck. “Thank you, Amy,” Roy’s mama said. Amy helped them lift Roy into the truck, then they drove down the hillside towards the hospital.
The next day, Betty came to Amy’s home. “I heard what you did,” Betty said. “You kept your head in an emergency. That’s an important skill.”
Amy’s face turned red. “I was afraid ...”
Betty shook her head. “It’s OK for a nurse to be afraid, as long as she has a clear head. The volunteer doctors are coming tomorrow with vaccines. We need some more hands. Can you help?”
“I’d love to.” Amy replied at once.
“Come early, then. There is a lot to learn.”
Amy smiled. “I’ll bring my first-aid book.”
