When Wang Deshun made waves in the fashion industry as a model in his late 70s, many people thought he had reached his apex (顶点). However, the 85-year-old showed them that he was still flying.

Wang took flight in Beijing’s Miyun district in a SW10 light aircraft (轻型飞机) on Aug 17, 2021. During the course of the flight, he completed turns and climbs on his own, becoming the oldest person to undertake (接受) flight training in China.

“I’ve been dreaming of flying for more than 50 years, so I thought I should learn to fly a plane. I thought I could do this,” Wang said. “It’s never too late to realize your dream,” he added. “Age has never been a problem. Just do it.”

This was not the first time Wang had wowed people. Born in a rural (农村的) family in Shenyang, Liaoning Province, in 1936, Wang started his career as a bus conductor (售票员) and then—a factory worker. In 1960, he became an actor and appeared in films such as Brave Journey to Northeast and Miss Granny.

Wang kept challenging himself all his life. At 44, he learned English and at 50, he began fitness training. He learned to ride a horse at 65, to ride a motorbike at 78, and hit the catwalk (T型台) at 79 when he joined in Beijing Fashion Week and rose to fame on social media (社交媒体). And at 85, he finally realized his dream of flying a plane.

16．Wang ________ on his own during the course of the flight.

17．The underlined word “this” in para.3 refers to “________”.

18．Wang worked as ________, a factory worker and an actor in his life.

19．Wang was 50 years old when he took up ________.

20．The passage mainly wants to tell us that ________.

Red and yellow can facilitate(促进) learning

Students usually prefer to study in environments with light colors. They say the light colors make them feel more relaxed, but researchers have found the opposite works better.

According to a study from Curtin University in Australia, the students’ concentration(专注) levels are higher when they are in environments with bright colors. In the study, the students were asked to read a passage and answer questions in rooms with different colors. They were light and bright blue, red and yellow. The students’ reading comprehension(阅读理解) scores were higher in the bright red and yellow rooms.

Aseel Al-Ayash, one of the researchers in the study, said, “Bright colors can support students’ learning performance by positively(积极地) affecting physical and mental states. If the reading tasks are difficult, the bright colour conditions may increase excitement to the best levels.” Several past studies have shown that the colors red and yellow are more stimulating(有刺激作用的) than blue and green.

However, two-thirds of the students in the study believed that bright red wasn’t a suitable colour for a study room. They connected the colour with depression(沮丧), discomfort, anger, danger and things like that. But they could improve their learning results by using the colour—so perhaps a bit of discomfort is what they need.

Maybe in the future, red and yellow will be the popular colors of study areas because of the study.

21．Students usually prefer to __________ with light colors.

22．The students’ concentration levels are __________ when they are in a room with bright colors.

23．If _________ are not easy, the bright color conditions may increase excitement to the best levels.

24．Several past studies thought that the colors ___________ are less stimulating than red and yellow.

25．Maybe in the future, _________ will be the popular colors of study areas because of the study.

The ways of celebrating New Year

On the night of December 31, people all over the world celebrate the arrival of the new year. Some home they can forget the troubles of the past year and start with a “clean slate(从头再来)”.

This year’s celebrations will be quite different. For example, the famous Times Square celebration in New York City will not have a crowd for the first time in 114 years. It will go online, allowing “visitors” to explore Times Square virtually(虚拟地) with an app. People can watch musical performances, enjoy a virtual fireworks show, and even take selfies(自拍) “on site”.

In the US city of Naperville, the “Countdown at the Carillon(钟琴下的新年倒计时)” event will also go online. It is held every year. People have recorded a video of the carillon bell striking(敲响) midnight, followed by bells playing Auld Lang Syne. When the video is posted online, everyone can keep the city’s tradition and count down to the new year together at home.

In London, Sydney and Vienna, New Year’s events also changed. There will be no public gatherings. But people can still gather at home, of course—with safety being kept in mind. Lifestyle website RealSimple has created a list of party tips, such as keeping an eye on people’s drinks to make sure they don’t accidentally(意外地) share the same cup.

I’m James, from America. I can’t sleep well and I always wake up several times during the night. I know for a fact that there are many other people who have trouble going to sleep, too. So, I’ve collected some advice over the past few months. They have not only helped me get to sleep faster, but helped me get better night sleeps.

Have regular sleep habits

Go to bed at the same time every night. Try not to break this habit on weekends when you may be made to stay up late. Wake up at the same time every day. If you are getting enough sleep, you should wake up naturally without an alarm.

Turn off your computer

Don’t play on the computer for half an hour before you decide to sleep. Studies show that it is bad for your sleep. Read a book or listen to some light music to prepare your body for sleeping.

Have a nice bedroom

A clean environment helps people to be happy and relaxed. Make sure that you have turned off all light that might come into your room, and that the temperature is comfortable.

Exercise often

Exercising will help you to fall asleep more easily, so walk out for 45 minutes every day and you will sleep better at night. But don’t do it just before you go to bed.

Interest is the best teacher. For Lu Qirui, running is her favorite. Lu, seventeen-year-old, is from Hangzhou, Zhejiang Province. She became famous after a video showed she finished a 100-meter sprint (短跑) in just 12.07 seconds.

She has to spend a lot of time on running, but she has never fallen behind others in her studies. She always makes full use of her time to do what she likes.

“I love sports, especially running, so it’s not challenging for me to hold on to it,” said Lu. In the future, Lu plans to make more achievements in running. As for her dream, she said, “I want to be a P.E. teacher so that more students can feel the happiness that sports bring to them.”

Stay in the shade on a sunny day

When I walk down the street in Beijing during the summer, I often find it quite difficult to get where I’m going. Why? Because of all the umbrellas in my way. Before I came to China, I’d never seen people carrying umbrellas on sunny days. But in China, women carry umbrellas when it’s not raining. What is the purpose, I wondered?

I found that there are many reasons for this. Firstly, it protects people from the sun’s rays（光线）. Many Chinese cities get hot in the summer. People sometimes carry umbrellas to stay cool.

But wait a second. If umbrellas can help us stay cool, why don’t I ever see men carrying them?

That brings us to the second reason-blocking（阻碍） the sun helps women’s skin stay pale（白皙的）. In China,   pale white skin is considered to be more beautiful than tanned（晒成棕褐色的）skin. Cosmetics（化妆品）companies even sell special creams and powders（香粉）to make your skin look whiter. Women in the US, on the other hand, actually prefer to be tan. It’s considered more beautiful there. Some people will lie outdoors in the sun for hours to get a tan. But doing this too much can be dangerous, as the sun’s rays are bad for your skin.

And as it turns out, China isn’t the only place where women carry umbrellas during the summer. Women in Greece are also known to carry umbrellas to protect themselves from the sun. So there you have it — umbrellas aren’t just for rainy days. Although I don’t think I’m going to start carrying one anytime soon.

41．I often find it quite difficult to get where I’m going because of __________ in my way.

42．People sometimes carry umbrellas to protect them from ___________ and stay cool.

43．In China, people considered that ____________ is more beautiful than tanned skin.

44．__________ outdoors in the sun too much can be dangerous, as the sun’s rays are bad for your skin.

45．From the passage we know that umbrellas aren’t just for _____________.
