A poor farmer had a friend 1 was famous for the 2 apple he grew. One day, his friend gave the farmer a(n)3 and told him to 4 it home. The farmer was 5 with the gift, but when he got home he did not know 6 to plant it.

    He was 7 that if he planted the tree 8 the road, the fruit would be stolen. If he planted the tree in one of his field, his neighbors would come 9 and steal some of the apples. If he planted the tree near his house, his children would take the fruit.

    10 he planted the tree in his wood where no one could see it. The farmer was very 11 of what he did. However, as time went on, he found that the tree didn't 12 any fruit. He didn't know without 13and good soil, the tree soon 14 after he planted it.

    Later the friend asked the farmer why he had planted the tree in such a 15 place. "What's the difference?" the farmer said 16. "If I had planted the tree near the road,17 would have stolen the fruit. If I had planted the tree in one of my field, my neighbors would have come and stolen some of the apples. If I had planted it near my house, my own children would have taken the fruit."

    "Yes," said the friend, "but at least someone could have 18the fruit. Now you not only have robbed every one 19 the fruit, but also you have 20 a good apple tree!"

    Chinese volunteers have completed a one-year test living in a simulated（模拟的）space lab in Beijing. The total length of the test, which started on May 10th last year, 1 370 days, thus setting a new record for the 2 stay in a simulated space lab.

    The space lab, called the Yuegong-1, or Lunar Palace 1, measures around 150 square meters. It 3 four sleeping rooms, a bathroom, a waste-treatment room and a room for raising animals. The Yuegong-1 provides everything humans need to survive in an environment 4 to that of a space station in outer space. Oxygen, water and food are 5 within it.

    A total of eight 6, all of whom are students at Beihang University, took turns 7 in the space lab. They were divided into 8 groups. On May 10, 2017, two men and two women 9 the Yuegong-1 for an initial （最初的）stay of 60 days. On July 9, they were 10 by another group of four, who stayed 200 days. The second group of students 11 on January 26, 2018, and the initial group12 and spent 110 days inside it.

    13, the volunteers were expected to stay in the Yuegong-1 for 365 days. But the project ended up 14370 days —from May 10 last year until May 15. The 15 five days were designed as a way to simulate a（n）16, in which the spaceship might experience a 17 in returning to earth.

    The goal of the project “Yuegong 365” is to 18 the limits of humans' ability to live in a 19 ecosystem for China's manned moon landing ambition. The success of the project means that China goes one step closer to putting 20 on the moon.

    At the beginning of our next class, I asked if someone wanted to share what happened when they told someone they loved them. As was usually the 1, I fully expected one of the women to2 , but on this evening one of the men raised his hand. He appeared quite moved and a bit3 .

    He began by saying, “Dennis, I was quite4 with you last week when you gave us this 5 I didn't feel that I had anyone to say those words to, and6, who were you to tell me to do something that is 7? But as I began driving home a8 deep down in my heart started talking to me. It was 9me that I knew exactly who I needed to say 'I love you' to. You see, five years ago, my father and I had a cruel 10and really never resolved it since that time. We 11seeing each other unless we totally had to at Christmas or other family 12. But even then, we13 spoke to each other. So, last Tuesday by the time I got home I had14 myself I was going to tell my father I loved him.”

    “It's15, but just making that decision16to lift a heavy load off my chest.”

    “When I got home, I rushed into the house to tell my wife what I was going to do. She was already in17 , but I woke her up anyway. She catapulted (弹射) out and 18 me, and for the first time in our married life she saw me cry. We19half the night drinking coffee and talking. It was20.”

    There was once a boy called Joseph Webb who always loved to show off how many friends he had at school. One day his 1 said to him, “Joseph, I 2 you a big bag of popcorn that you don't have as many friends as you think. I'm sure many of them are nothing more than companions.”

    Joseph 3 the bet at once. However, he wasn't sure how to 4 whether his schoolmates were real friends or not, so he asked his grandfather. The old man answered, “Wait a minute.” Then he left and 5 soon as though carrying something in his hands, but Joseph could see 6 there.

    “Take it. It's a very 7 chair because it's invisible (看不见). It's rather 8 to sit on, but if you take it to school and 9 to sit on it, you'll activate (激活) its 10 and it'll be able to tell who your real friends are.”

    Joseph, brave and determined, set off for 11 with the strange and invisible chair. At break time he asked everyone to form a(n) 12, and he put himself in the middle, with his chair. Having difficulty seeing it, Joseph tried to sit on it but he 13 the seat and fell straight onto his backside. Everyone around him had a pretty good 14.

    Wait! Let me try again, Joseph said. But again, he missed the seat, 15 more surprised looks and a few catcalls (尖叫,喝倒彩). Joseph didn't 16 and kept trying to sit on the magic chair. But he kept falling to the ground…until, suddenly he tried again but didn't 17. Looking around, Joseph saw three of his best friends holding him up. 18, many others he had thought of as friends had done nothing but make fun of him. And there, the show came to an end. Joseph understood that 19 friends were those who care for him, and not just the 20 that happened to be passing by. And someone who took joy in his misfortunes (不幸) was even less of a friend.

    One afternoon, I went to pick up my mother from work. 1, I looked outside the car window, there was a small park 2 I saw a little boy running freely on the grass as his mother watched from a short distance. The boy would then fall to the grass, 3 , and without hesitation or without looking back at his mother, run as fast as he could, again, still with a smile on his face, 4 nothing happened.

    When they fall down, kids don't 5 their falling down as a failure, but 6, they treat it as a learning experience, 7 just another result of outcome. They try and try again 8 they succeed. They haven't associated “falling down” with the word "9" yet, thus they don't know how to feel the state which accompanies failure. So they don't 10. Plus, they probably think to themselves that it's perfectly okay to fall down, and that it's not 11to do so. In other words, they give themselves 12 to make mistakes, subconsciously.

    While I was13by the boy's persistence, I was equally touched by the 14 in which he ran. With each attempt, he looked so confident… so natural. His only aim was to run freely and to do it as effectively as he could. He was just being a child—just being himself—being completely in the moment. He was not looking for approval or was not worrying about15 someone was watching. He wasn't 16 about being judged. He didn't seem to be bothered by 17 that maybe someone would see him fall. No, what 18 to him was to accomplish the task or activity 19 to the best of his ability.

    I learned a lot from that 20 and experience, and have successfully brought that lesson with me in my life.

I went to a group activity, "Sensitivity Sunday", which was to make us more1the problems faced by disabled people. We were asked to "2 a disability" for several hours one Sunday. Some members, 3, chose to use wheelchairs. Others wore sound­blocking earplugs (耳塞) or blindfolds (眼罩).

Just sitting in the wheelchair was a4experience. I had never considered before how5it would be to use one. As soon as I sat down, my6 made the chair begin to roll. Its wheels were not7. Then I wondered where to put my   8. It took me quite a while to get the metal footrest into9. I took my first uneasy look at what was to be my only means of 10for several hours. For disabled people, "adopting a wheelchair" is not a temporary (临时的)    11.

I tried to find a12position and thought it might be restful, 13 kind of nice, to be14 around for a while. Looking around, I15 I would have to handle the thing myself! My hands started to ache as I16the heavy metal wheels. I came to know that controlling the17 of the wheelchair was not going to be a (n)18task.

My wheelchair experiment was soon 19. It made a deep impression on me. A few hours of "disability" gave me only a taste of the20, both physical and mental, that disabled people must overcome.
