It was getting dark when I got home. It was cold and I     1    (wear) a coat. I walked up to the door and put my hand into my pocket     2    (take) out my key     3     I couldn’t find it. I suddenly remembered that I     4    (leave) it on my desk in the office. It really didn’t make any difference. I knew my wife     5    (be) at home and the children must have come back from school by now, so I     6    (knock) at the door.

There was no answer, so I knocked again. I continued knocking at the door for some time. I     7    (get) angry. Then I remembered something the office boy had told me at noon. He said that my wife     8     (phone) saying that she     9    (go) shopping in the afternoon with the children.

There was only one thing for me to do: I had to clime in    10     a window.

When someone has deeply hurt you, it can be very difficult to let go of your anger. But forgiveness is possible — and it can be surprisingly     1     (benefit) to your physical and mental health. So far, research     2    (show) that people who forgive can have more energy, better appetite and better sleep. "People who forgive show    3    (little) anger and more hopefulness," says Dr. Fre deric Luskin, who wrote the book Forgive for Good. So it can help reduce the tiredness out of the immune system and allow people     4    (feel) more energetic."

So when someone has hurt you, cool down first. Take a couple of breaths and think of something     5    gives you pleasure: a beautiful scene in nature, or someone you love. Don't wait for an     6     (apologize). “Many times the person who hurt you may never think of apologizing," says Dr. Luskin. "They may have wanted to hurt you or they just don't see things in     7    same way. So if you wait for people to say sorry, you could be waiting a very long time."

Next keep in mind that forgiveness does not necessarily mean     8    (accept) the action of the person who upsets you. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person's perspective. You may realize that he     9    she was acting out of ignorance. To gain perspective, you may want to write a letter to     10    (you) from that person's point of view.

So far, China Eastern Airlines    1    (receive) approval(批准)fiom the Ministry oflndustry and Information Technology to offer in- flight Wi-Fi service on 21 airplanes.

The carrier becomes China's first airline company    2    （provide) Wi-Fi service for both domestic and international flights. Passengers    3    (leave) for New York, Los Angeles, San Francisco, Toronto, Beijing and Guangzhou will have access    4    me Wi-Fi service through a telecommunication satellite.

The flights will begin to provide the service in one month after operational    5    （prepare). The Wi-Fi service will be free in the 21 airplanes at the beginning,    6    a charge list is now under discussion.

The company plans to put in Wi-Fi service    7    (equip) in all airplanes by 2019-2020. Other carriers in China, such as Air China and Hainan Airlines also have been following this attempt in some oftheir flights during the past few years.

Industry experts note that    8    approval for the Wi-Fi service on 21 airplanes.is a trial for commercial in-flight Internet service operations in China. Aviation(航空)business staff say that China has the potential to become the world's     9    (large) aviation market,    10    is likely to create tens of billions of yuan in profit in the aviation Internet business.

China is home to different kinds of soybeans. In 2011, the soybean output of China dropped     1    the fourth place around the globe,     2     （account）for only 5.55% of the world’s total. China now relies    3    (much) on import to meet a domestic(国内的) need for the plant than ever.

Actually, Gai Juyi is one of the millions of diligent Chinese people    4    (work) hard to change the situation. For over two     5    (decade), Gai and his team went into various fields across the country just to collect seed from the farmers. “None of the seeds is the same.” he said. Seed collection is already no easy job. And they even     6    (have) to delay the process from time to time because of a lack of funding, many of Gai’s students left    7     industry for the small financial payback.     8    , Gai has remained in his post and spared no efforts in looking after the precious seeds.

The hard work of Gai and his team    9    (final) paid off. Thanks to them, China’s soybean harvest doubled over the years. The old man said, “I know     10    my persistence means when I see self-produced tofu and soybean milk on Chinese people’s table.”

Who is smarter？A human being or artificial intelligence？The question     1    （sweep）across the world when a Google-developed program called AlphaGo defeated the world top player. So，what comes next？

Some people are pessimistic，saying that the full development of artificial intelligence，    2     AI in short，could mean the end of the human race. So are we really about to live in the world     3    （show）in the Terminator（终结者）movies？

“Not quite，”answered John Markoff of The New York Times，    4     is optimistic about the future. “We think that，for the human beings，things like sight and balance，    5    （be）natural and ordinary in our life. Also，we humans are better at making     6    （adjust）to the surroundings. We have a long way to go before AI can     7    （true）begin to be similar to the human brain，even though the technology can be great.” Meanwhile，John Markoff said that researchers should build artificial intelligence to make people more     8    （effect）.

“Our fate（命运）is     9     our own hands，”he added.“Since technology depends on the values of     10     (it) creators, we can choose to use technology to improve the world.”

The giant panda     1     (love) by people throughout the world. Chinese scientists     2     (recent) had a chance to study a wild female panda with a newborn baby. She was a very     3    (care) mother. For 25days, she never left her baby, not even to find something     4     (eat)! She would not let any other pandas come near. She licked the baby constantly to keep it clean. Any smell might attract natural     5    (enemy) that would try to eat the little comforting panda. The mother held the baby in her front paws much the way a human does.     6     it cried, she rocked it back and forth and gave it little comforting pats. The mother continued to care for the young panda     7     more than two years. By that time, the panda no longer needed     8    (it) mother for food. However, it stayed with her and learned about the ways of the forest. Then, after two and a half years, the mother     9     (drive) the young panda away. It was time for her to have a new baby,     10     it was also time for the young panda to be independent.
