Zhang Kai is a university student. He _______ a group of college student volunteers since last year. They help children at a primary school _______ their studies and daily lives.

“When I was a small child,” Zhang said, “I knew March 5th was a day for people to learn from Lei Feng and help others, _______ I didn’t know the real meaning of the spirit of Lei Feng. Now when I see the smiling faces of the kids I have helped, I _______ understand Lei Feng. Helping others makes me happy.”

Lei Feng (1940—1962) is one of _______ soldiers in Chinese history. He lost _______ parents when he was very young. His neighbors _______ him up. He died in an accident at 22. He did many good deeds（好事）in his short life. For example, he gave his own money to the parents of another soldier. And he bought tickets for a woman he didn’t know without _______ her his name. On March 5th, 1963, people _______ on to learn from Lei Feng by Chairman Mao.

Today more than 60 years has passed. Some people say that the spirit of Lei Feng is outdated. But many people think we need to advocate（提倡）that spirit __________ more people.

My child and I were in the garden building our shed (小棚), with a group of kids from the neighborhood around us. Everyone was ________ to join in the wonderful building project.

A boy came by with a beautiful bird ________ on his shoulder. Other kids all ran towards him. I asked the boy,   “Why doesn’t the bird fly away?” To my surprise, he answered that its wings were ________ . After hearing that, I replied, “That’s ________ ! You have hurt it by taking away its chance of development.” Hearing my words, the boy’s face turned red. Then I added, “This is what some people do to their ________ . They don’t give their encouragement, which makes their children feel that they can ________ succeed. Isn’t that cruel? “

Just then my 10-year-old son Jack started shouting, “ ________ me!” He was swinging (摇摆) with two wings made of a large piece of cardboard on his back. Other kids laughed when seeing him. I said seriously,   “He just has the ________ to do what he wants to do and hopes to get attention. Just make sure we get the attention we want in a way that is not ________ .”

I was happy that I could share the ________ with the kids. When I sat in the garden in the shining sun, I imagined how my kids would spread their wings and fly.

Could you imagine cars driving without human drivers? Recently, China has made a big step toward self-driving technology. This August, more and more driverless taxis run on roads in many big cities in China.

Why do we develop self-driving cars? Self-driving cars give us many benefits. They use computers to sense the things around them and make better use of space. This means fewer traffic jams and better parking of cars. Many people cannot drive for various reasons, including age, disability, or lack of experience. Now, they can get around more easily. Driving becomes more convenient.

According to a research, each year, over 1.3 million people die in car accidents around the world, and many more get hurt. Self-driving cars can reduce (减少) road accidents by 90% and save a lot of money. The main cause of car accidents is human mistakes. By using computers, self-driving cars don’t make poor decisions or lose attention like humans do. They can improve driving safety.

But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react (反应) as fast as a human driver can. Also, during weather events like heavy snow, it will be difficult for self-driving cars to see the lines on the road. It might lead to an accident. The computer system in the car can also get hacked (非法入侵) by someone, causing it to crash.

It’s clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads. And China is taking the lead in making this happen.

Wuyi Rock Tea is a kind of Oolong tea. It got its name from the place where it’s produced—Wuyi Mountain in Fujian Province. The tea trees usually grow on rock cracks（缝隙）. The traditional home of Rock Tea is only from a small area in the mountain. Wuyi Rock Tea is famous for its rich smell and good flavour. There are different kinds. The best is Dahongpao.

With its long history, Wuyi Rock Tea dates back to the Shang Dynasty. People used to send it to the emperor as a tribute（贡品）. In 2006, the skills of making Wuyi Rock Tea were added to China’s national intangible cultural heritage list.

Zhang Huichun, 65, is a master of making Wuyi Rock Tea. In 1980, he learned to make the tea and opened a tea factory. To his surprise, the skills were very complex. After 10 years of learning, he could finally make the tea by himself. Zhang said there were 13 steps to make it, including drying, shaking and roasting（焙火）. The most challenging for him is shaking. It takes strength and patience to shake the tea leaves by holding the round bamboo trays. “You have to decide when the best time is to stop based on the color,” Zhang said. “Sometimes you stop after shaking dozens of（几十）times, while sometimes it can be hundreds of times. Only years of experience can help you figure it out（弄明白）.”

“The last step—roasting—is also important. With three stages, it usually takes more than 20 hours! Each stage needs temperatures from 125℃ to 155℃. Tea makers have to keep a close eye on the process. Every 50 minutes, you have to turn over the leaves, or it might burn,” Zhang said.

Zhang is already a master, but he is still learning. “The most fascinating part is that every step is full of changes—different tea trees, weather and temperatures. Every time is an adventure.”

In recent years, Zhang has often worked with schools to train tea makers. “It’s my responsibility to pass on the traditional skills,” he said.

How do you feel when you walk into a messy room?     46     What about walking into a clean, organized room with your favourite furniture and colors? How does that make you feel?     47    

Sometimes, going online can feel a bit like going into a messy room.There’s just so much stuff in there, and it doesn’t seem to have any order.     48     What’s more, much of it is quite useless.

It’s good to think of the Internet world as its own environment, and it’s good to remember that you can create your own room in this environment. If you want a cleaner room, then you’ll need to start organizing it.     49     For example, if you’re a fan of video apps, you’ll know that you have endless videos to watch. But if you want to keep your online room clean, you might need to make sure that these apps don’t take up too much space in it. To do this, you’ll need to limit (限制) how much time you spend on them.

By making little changes to our online habits, we can live a more relaxed life and have a less messy mind.     50
