2．　　On Feb. 12th, 2020, Dalian (not his real name) was taking a train to Changsha, Hunan, for a business trip. While on the train, he went into a carriage (车厢) to have lunch and chose to remain in the carriage. He didn't know that the carriage was only for people heading to Wuhan.
　　Several hours later, when the train arrived in Wuhan, Dalian was asked to get off, as he was in the special carriage. Although he was surprised, he didn't want to cause trouble and got off the carriage with just a single bag.
　　Because of the epidemic(流行病), Wuhan had been locked down. So Dalian couldn't find a hotel to stay in. Feeling at a loss, he saw a notice online looking for volunteers to work in hospitals. Dalian decided to give it a try.
　　He soon became a volunteer in Wuhan No. 1 Hospital. He was responsible for taking out rubbish, sweeping the floor, disinfecting (消毒) the hospital, dealing with used protective suits (防护服) and bringing meals to patients.
　　The young man, reportedly from Northeast China, had to work 12 hours every day, changing his protective suit three times a day. While working, he couldn't drink anything or go to the bathroom. He also had to have close contact with infected patients, which is risky (冒风险的).
　　Dalian was afraid of getting infected at first. "When I entered the wards (病房), I was kind of frozen (僵硬的) and felt like I couldn't move, " he said. But after he saw more patients get better, his fear gradually went away.
　　Dalian's story has gone viral (走红的) online. People were surprised by his experience, and described him as having "a heart of gold".

3．　　Holidays play an important part in our life. We work hard during the year, so we feel tired and stressed at times. We need holidays to relax, even if they only last for a few days. This is especially true for women. They could get away from their husbands, children and family for even one week in the year.
　　Holidays have many good results. Firstly, they can improve the economy(经济). If there were no holidays, people would have little time to spend the money they earn. Secondly, holidays allow people to relax after working hard throughout the year. During and after the holidays, people feel more relaxed and energetic;they then bring this energy to work when they continue working. Lastly, holidays help people learn how to enjoy life. Most people improve their relationships with their other family members during holidays.
　　However, holidays also have bad aspects(方面). For example, many people said that they couldn't enjoy shopping or travelling because there were so many people shopping and travelling, too. Anyway, most people realize that they need holidays. I can't imagine what people's lives would be like if there were no holidays.

4．　　No one wants to work at a messy desk and look lazy. But does a messy desktop actually mean that?Not all disorders (无序) mean you mess everything up. Even Steve Jobs thought his personal attraction came from his messy desktop.
　　People who prefer a messy desk have their own ideas. Some think it makes them comfortable. Some believe it helps them focus more easily. Messy tables can make it easier to focus on the tasks, just like some novelists can write patiently in a noisy café. Others may be the people who want to do things perfectly. For those who strive for perfection, tasks are either 100% or 0% done. So they usually put away the less important things and do the most important ones perfectly, which leads to paper mountains on the desktop.
　　Many people are described as untidy, careless and slow because of messy tabletops. However, when we see the desks of Albert Einstein, Mark Twain and Mark Zuckerberg — pioneers of their times — things might change. Clearly, the world welcomes uniformity (一致) and order, it also never refuses regular (有规律的) disorder, which seems like a mess but goes in an organized (有条理的) way.
　　Research shows that people working with a messy desktop are probably more creative and like to take risks. But people with a tidy one often follow the rules and may not like to try new things. For example, in an experiment (实验) done by Kathleen Vohs, people in the messy group came up with more interesting and creative ideas about the new uses of ping﹣pong balls than the organized one. Vohs says, "Messy environments seem to inspire people to think up fresh ideas. "
　　But a messy desk might not be the best choice all the time. When you need new ideas, a messy desk might be a good choice;but when you want to do a task quickly and successfully, it seems better to make a desk clean and tidy.

13．　　There are many teenagers who have too much pressure. Last Wednesday, Mr. Trent began his psychological (心理的) health class (1)      holding up a glass of water. He asked the students what would happen if he held it up for a day. A student said the teacher's arm would ache or go numb(麻木的). He might have to go to hospital!All the students laughed.
　　"But during the time, did the weight of the glass change?" asked Mr. Trent. "Then what (2)       (cause) the pain and numbness?"
　　The students (3)       (puzzle) by the question.
　　"What should I do now (4)       (get) rid of the pain?" asked Mr. Trent again.
　　"Put the glass down!" said another student.
　　"Exactly!" said Mr. Trent. "Life's problems are something that caused the pain like this glass. Hold them for a few(5)       (minute) in your head and they seem OK. Think of them for a long time and they begin to ache. "
　　It's important to think of the challenges or problems in your life. But what's even more important is to put them down at the end of every day.

14．　　My family moved to America last year from a small town in north China.
　　I had a part﹣time job (1)       a waiter in a Chinese restaurant. One day, when I was serving food to a middle﹣aged couple, the wife asked me how I could bring their food so quickly. I told her I always respected the elderly. I found her (2)       (happy) when she heard that. My manager heard my words and told me in a low voice that Americans were sensitive(敏感的)and hated the description of "old". Then I walked back to the table and politely said sorry to the wife.
　　In the USA, people think "growing old" is a problem. Here many people try to keep (3)       (them) away from growing old by exercising, like jogging or swimming. When I told the couple I respected the elderly, they got angry because this made them feel they failed to stay young, they didn't want to hear that.
　　Now I (4)      (change) the way I treated the elderly. I still respect them, but now in a different, (5)      (little) direct way.

15．
　　One sunny morning, when Zebra(斑马) visited the river for a cool drink, he heard a tiny voice. "Help me, Zebra!"
　　Zebra looked around and found Wasp(黄蜂) (1)       by a spider web in a thorn bush (荆棘丛). Carefully, Zebra reached into it, but the thorns hurt him. "Ouch!" Zebra stepped back and was leaving.
　　"Please help me, " said Wasp. "One day I will (2)       your help. "
　　Zebra laughed. "I'm fast and strong. Besides, I have a big family. Why would I need help from a (3)       wasp?"
　　"Please try one more time, " Wasp said. Zebra knocked at the web. Luckily, this time it was enough to free Wasp. "Try to stay out of trouble, " Zebra said. "I might not be nearby the next time a spider gets (4)      . " Then he left.
　　All day, Zebra stayed with his family until he noticed his favorite fruit—some berries!The hungry Zebra ran to (5)       the berries.
　　Wasp was resting in the bushes when she saw Zebra. She also found Lion hiding quietly ahead. If Zebra got too close to Lion …
　　Thinking quickly, Wasp flew down and gave Lion a sudden sting. The (6)       lion cried. "Roooooaaar!" Zebra heard the loud cry. In a second, he turned around and ran back family.
　　A moment later, Wasp flew around Zebra's head. "Try to stay out of trouble, " Wasp said with a (7)      . "I might not be nearby the next time a lion gets hungry. "

16．　　When learning is mentioned, regular school (正规学校) can be the first place which you can think of. However, the Internet is changing the way students learn. Many learning apps provide rich courses (课程) for the learners to meet their levels of knowledge and interests. With the Internet, learners are allowed to learn at home or anywhere else.
　　*Which do you prefer:Regular School or Home School?
　　Amelia, 14.
　　Regular school helps you learn more. And you have more chances to take part in clubs and try out different kinds of courses. In class, you can discuss problems by working in groups.
　　Miya, 15.
　　I prefer regular school. I can have more friends and work with more people in groups. When I was having classes at home, I disliked it.
　　Scott, 15.
　　I prefer having classes online because I can spend more time learning when I am the only student in "my class". Having classes at home may make me very independent.
　　Michael, 16.
　　If you are a slow learner, you may fall behind in regular school. But if you have classes at home, you can learn well. I'm having classes at home and I make much more progress now than when I went to regular school.
　　*What can you do to improve your online studies?
　　To successfully learn online, you can follow these steps. First of all, you should always keep in mind what you hope to complete by the end of it. Then a study plan is needed. A good study plan includes a study calendar and a to﹣do list. Next, when having a class, be active to think about what the teacher says and express yourself. After class,remember to review what you have learned by reading your notes or making a mind map.

　　With the coming of 5 G, the cloud classroom might not be far away. However, whatever advantages online learning has, it just offers a way of learning. It doesn't take the place of any of the ways. There must be more ways of learning in the future. Nobody knows what will happen.
