    Nearly 7,000 medical workers in the team supporting Central China's Hubei province left the capital, Wuhan, the hardest-hit city in the novel coronavirus outbreak in China, and went back to their hometowns on Tuesday, March 31, marking the largest scale departure (离开) of medics (医学工作者)since the first group left on March 17. The Civil Aviation Administration of China has organized 51 planes to support the departure.

    More than 42,000 medics from other parts of the country have joined the battle with local medics to fight against COVID-19. The support teams came from 21 provinces, cities and autonomous regions(自治区) and some of them worked on several battlefields during the past months. The support team from the First Hospital of China Medical University in Shenyang, was among those in the group. Sixty members were in charge of treating COVID-19 patients in 100 beds in the Union Hospital and treated 174 patients who have been seriously ill since they arrived on Feb 10.

    Wang Zhenning, the leader of its support team, expressed his thanks to the Wuhan people who offered great help to them. "I am proud to witness and play a role in history. We've been here, seen it happen and become better. Wuhan is our second hometown. We will forever care about the city and the people fighting with us." he said.

    Wuhan city government showed great thanks to all medics in a letter, expressing their gratefulness of the medics' efforts to save lives in the battle. "Thanks to your arrival, Wuhan welcomes today's peace and stability. We will always remember your kindness!" the letter said. In it, the city government also invited the medics to visit Wuhan in the future for sightseeing. Local people volunteered to line up and see medics off as the medics left for home after finishing their mission(使命) in Wuhan. Wuhan traffic police led the way for medics to the airport.

I was walking along a busy road when I noticed a young man standing near the crossing selling toys.1I would hurry past such sellers. But I found this young man was 2, so I stood for some time without crossing the street. I wanted to see how he sold his things.

Soon, a young mother with a little girl came by and the child set 3 eyes on one of the teddy bears. The mother asked the 4 and it was only one dollar. She 5 out a 10­dollar note from her handbag and told the young man that she was giving him 10 dollars and wanted the 6 back. I was wondering how he was going to do it. He told the young mother to put the money in the bag 7 around his neck and take out her change.

I realized that this young man depended on believing people would not cheat him. There was no way for him to know 8 someone took out more than they should have done. I was so 9. I bought a car model from him that I did not need. As I walked down the street, I gave the car model to a kid walking with his father.

I kept thinking that the world would be a better place if we could all learn to 10others more, like the young blind street seller.

阅读下列短文, 从下面每个小题的A、B、C、D四个选项中选出最佳选项。

One day, Ben was playing basketball in the living room, breaking a vase. To cover his terrible action, the frightened boy glued the pieces together and put the vase back to its place.

That evening her mother noticed the cracks (裂纹). But to her surprise, the repair work was actually very good. At dinner time, she asked her boy if he broke the vase. Fearing punishment, the boy said that a neighbor's cat jumped in from the window and knocked the vase off. His mother was quite clear that her son was lying. However, she said nothing.

Before going to bed, the boy was asked to go to the study. In the study, his mother didn't look angry. On seeing her son carefully come in, she gave him one chocolate, saying "This chocolate is a reward (奖励) for your imagination: a window-opening cat!" At that moment, the boy felt the chocolate was a hot potato. “Did mom find holes in my excuse?” he thought. “You know, all the windows were closed.” Mother continued calmly and took out two chocolates into his hand, “An award for the perfect repair.”

Now with the chocolates in hand, the boy wished the ground to open up and bury him! He told the truth. “So I have to punish you for your lie.” The mother said with a serious voice and took back his chocolates. The boy bent down his head in shame. “But your honesty should have the award—a box of chocolates.” The mother suddenly bent to kiss his cheek, speaking gently to the crying boy, “My son, honesty values more than anything.”

Astronauts would face dangers both getting to and surviving (生存) on Mars. Let's learn about surviving a trip to Mars.

What would it take to keep people safe and healthy on a trip to Mars? Scientists are already working on it, though the trip may be many years later.

Over the last 60 years, many spaceships have flown by orbited（沿轨道运行）and even landed on the Red Planet. However, machines cannot replace humans. That's why the United States, China and other countries want to send people to Mars. But surviving on this trip would not be easy.

A trip to Mars would be the farthest journey in human(人类) history. Mars is about 225 million kilometers away, so it would take astronauts at least 180 days to reach there. However, it only takes a few days to get to the Moon.

Space travel is dangerous. For one thing, staying in space for long periods makes the human body weak. Also, it puts pressure behind the eyes and causes eye problems. But gravity(重力) machines could help.

Then there's space radiation(辐射) to worry about. It is bad for astronauts when they have long journeys. Scientists are working out the issue. They have found that taking certain vitamins can help.

Astronauts will have to pack light to lift off from the earth. But they won't be able to get the things they need easily. Astronauts on the space station practice for this by growing lettuce and other food in space. Engineers are developing 3D printing techniques（技术）which can allow future Mars astronauts to build what they want.
