阅读理解

    Another thing an astronaut has to learn about is eating in space.Food is weightless, just as men are.

    Food for space has to be packed in special ways.Some of it goes into tubes that a man can squeeze into his mouth.Bite-sized cookies are packed in plastic.

    There is a good reason for covering each bite.The plastic keeps pieces of food from traveling in the spaceship.On the earth very small pieces of food would simply fall to the floor.But gravity doesn't pull them to the floor when they are out of the plastic in a spaceship.They move here and there and can get into a man's eyes or into the spaceship's instruments.If any of the instruments is blocked, the astronauts may have trouble getting safely home.

    As astronauts travel on longer space trips, they must take time to sleep.An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat.But be careful he must put his hands under the belt when he goes to sleep.This is because he is really afraid that he might touch one of controls that isn't supposed to be touched until later.

(1)、Why would astronauts cover each bite of food in space?
A、Because small pieces of food would fall down to the floor. B、Because weightless pieces of food might make trouble when they travel around. C、Because they haven't enough food for longer trips. D、Because astronauts don't want to waste food.
(2)、In a spaceship, astronauts can ________.
A、walk just as they do on the earth B、not eat anything because it's dangerous C、control the spaceship when they are sleeping D、not litter small things or it will make trouble
(3)、Why does an astronaut put his hand under his belt when he sleeps?
A、Because he thinks it is comfortable to sleep in that way in space. B、Because he doesn't want to touch any controls when he sleeps. C、Because the instruments of the spaceship are easily broken. D、Because he is afraid that the seat will move.
(4)、What is the best title of this article ?
A、Eating and Sleeping in Space B、How Astronauts Eat in Space C、Food for Space D、How Astronauts Sleep in Space

    I told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, "You mean fortunately." He explained that I should be glad of the extra exercise that the hill provided.

    My attitude to the hill has now changed. I used to complain as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smile of satisfaction as I reach the top of the hill.

    Problems are there to be faced and overcome. We cannot achieve anything with an easy life. Helen Keller was the first deaf and blind person to gain a university degree. Her activism and writing proved inspirational. She wrote, "Character cannot be developed in ease. Only through experiences of suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved."

    One of the main determinants of success in life is our attitude towards adversity (逆境). From time to time we all face hardships, problems, accidents and difficulties. Some are of our making but many are no fault of our own. While we cannot choose the adversity, we can choose our attitude towards it.

    Douglas Bader was 21 when in 1931 he had both legs cut off following a flying accident. He was determined to fly again and went on to become one of the leading flying aviators in the Battle of Britain with 22 aerial victories over the Germans. He was an inspiration to others during the war. He said, "Don't listen to anyone who tells you that you can't do this or that. That's nonsense. Make up your mind, you'll never use crutches (拐杖) or a stick, and then have a go at everything. Go to school, and join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible."

    The biographies (传记) of great people are full of examples of how they took steps to overcome the difficulties they faced. The common thread is that they did not become depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.

    Nevertheless, there is still the problem of how you change your attitude towards adversity.

    Jack Ma's net worth increased $2.8bn overnight as Alibaba forecast sales growth that topped every analyst's estimate, despite the fact that China's economy is slowing down.

    Mr. Ma, aged 52 this year, is now the richest person in Asia and 14th wealthiest in the world, according to the Bloomberg Billionaires Index. His net worth has climbed $8.5bn this year to $(4)8bn.

    The latest surge came after China's largest e-commerce company forecast 45 to 49 percent revenue(收入) growth in the year ending March, demonstrating how investments beyond online shopping are paying off. Shares in Alibaba, where Mr. Ma is chairman, rose 13 percent to a record high.

    Alibaba and Tencent, which dominate online shopping and social media, respectively have ventured(冒险) deeper into new areas from cloud computing services to streaming music and video as the country's economy slows. Alibaba is capturing more digital advertising spending by incorporating(合并) social elements such as video in its shopping sites.

    Alibaba is holding meetings with investors this week. On Friday, the former English teacher said he wasn't going to discuss corporate forecasts. He took the stage instead to describe how his company had become effectively the world's 22nd largest economy—just after Argentina—in terms of transaction(交易) by never fearing to think big. Mr. Ma, who said Alibaba revises 10-year plans annually, foresaw the company becoming the fifth-largest eventually by 2036 by serving a burgeoning Chinese middle classes, taking advantage of global trade and making use of its valuable data.

    Ma's comments about the evolution of data-driven technology echoed Masayoshi Son, Chairman of Japan's SoftBank. SoftBank—Alibaba's largest shareholder—has invested billions in companies such as ARM with the intention of staking out a leading position in the future Internet of Things.

    “The Internet of Things is going to be big because in the past, machines drink electricity,” Mr. Ma told investors. “In the next 20 years, machines will drink data. In the future, no company, no country, no business can survive without data.”

    John Blanchard stood up from the bench, straightened his Army uniform, and studied the crowd of people making their way through Grand Central Station. He looked for the girl whose heart he knew, but whose face he didn't, the girl with the rose.

    His interest in her had begun thirteen months before in a Florida library. Taking a book off the shelf he found himself intrigued, not with the words of the book, but with the notes penciled in the margin. The soft handwriting reflected a thoughtful soul and insightful mind. In the front of the book, he discovered the previous owner's name, Miss Hollis Maynell. With time and effort he located her address. She lived in New York City. He wrote her a letter introducing himself and inviting her to correspond. The next day he was shipped overseas for service in World War II.

    During the next year and one month the two grew to know each other through the mail. Each letter was a seed falling on a fertile heart. A romance was starting Blanchard requested a photograph, but she refused. She felt that if he really cared, it wouldn't matter what she looked like.

    When the day finally came for him to return from Europe, they scheduled their first meeting —7:00 PM at the Grand Central Station in New York. “You'll recognize me,” she wrote, “by the red rose I'll be wearing on my lapel.” So at 7:00 he was in the station looking for a girl whose heart he loved, but whose face he'd never seen.

    I'll let Mr. Blanchard tell you what happened: A young woman was coming toward me, her figure long and slim. Her blonde hair lay back in curls from her delicate ears; her eyes were blue as flowers. Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive. I stared at her, entirely forgetting to notice that she was not wearing a rose. As I moved, a small, attractive smile curved her lips. “Going my way sailor?” she murmured.

    Almost uncontrollably I made one step closer to her, and then I saw Hollis Maynell. She was standing almost directly behind the girl. A woman well past 40, she had graying hair tucked under a worn hat. She was more than plump, her thick-ankled feet thrust into low-heeled shoes. The girl in the green suit was walking quickly away. I felt as though I was split in two, so keen was my desire to follow her, and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own.

    And there she stood. Her pale, plump face was gentle and sensible, her gray eyes had a warm and kindly twinkle. I did not hesitate. My fingers gripped the small worn blue leather copy of the book that was to identify(识别)me to her.

    This would not be love, but it would be something precious, something perhaps even better than love, a friendship for which I had been and must ever be grateful. I squared my shoulders and saluted and held out the book to the woman, even though while I spoke I felt choked(哽咽)by the bitterness (痛苦)of my disappointment. "I'm Lieutenant (中尉)John Blanchard, and you must be Miss Maynell. I am so glad you could meet me; may I take you to dinner?"

    The woman's face broadened into a tolerant smile. "I don't know what this is about, son," she answered, "but the young lady in the green suit who just went by, she begged me to wear this rose on my coat. And she said if you were to ask me out to dinner, I should go and tell you that she is waiting for you in the big restaurant across the street. She said it was some kind of test!"

    It's not difficult to understand and admire Miss Maynell's wisdom. The true nature of a heart is seen in its response to the unattractive. "Tell me whom you love," Houssaye wrote, "And I will tell you who you are."

    I had worried myself sick over Simon's mother coming to see me.I was a new teacher,and I gave an honest account of the students' work.In Simon's case,the grades were awfully low.He couldn't read his own handwriting.But he was a bright student.He discussed adult subjects with nearly adult comprehension.His work in no way reflected his abilities.

    So when Simon's mother entered the room.my palms(手掌心)were sweating.I was completely unprepared for her kisses on both my cheeks."I came to thank you,"she said,surprising me beyond speech.Because of me,Simon had become a different person.He talked of how he loved me,he had begun to make friends,and for the first time in his twelve years,he had recently spent an afternoon at a friend's house.She wanted to tell me how grateful she was for the self-respect I had developed in her son.She kissed me again and left.

    I sat,stunned,for about half an hour,wondering what had just happened.How did I make such a life-changing difference to that boy without even knowing it?What I finally came to remember was one day,several months before, when some students were giving reports in the front of the class,Jeanne spoke quietly,and to encourage her to raise her voice,I had said,"Speak up.Simon is the expert on this.He is the only one you have to convince,and he can't hear you in the back of the room."That was it.From that day on,Simon had sat up straighter,paid more attention,smiled more,and became happy.And it was all because he happened to be the last kid in the last row.The boy who most needed praise was the one who took the last seat that day.

    It taught me the most valuable lesson over the years of my teaching career,and I'm thankful that it came early and positively.A small kindness can indeed make a difference.

    In the winter months the temperature in most of Canada usually stays below 0℃. However, in some parts of Canada, such as southern British Columbia, the temperature rarely goes below 0℃. In most areas where people live, snow will be on the ground from mid-December to mid-March. Though Canada's winter may be much colder and longer than you are used to, it can be very enjoyable. For many Canadians, being active in winter is an important part of enjoying life. There are many outdoor winter activities, including skiing, ice fishing, walking, and skating. Joining in one of these activities may help you appreciate winter and enjoy your time outside in the snow.

    Dressing for winter

    During winter in Canada, you will need warm clothing. If possible, arrive with these items or be prepared to buy them soon after your arrival. You will need:

    a warm waterproof boots   ☆ a scarf for your neck

    a hat that covers your ears  ☆ gloves for your hands

    thick winter coats, pants and sweaters

    Layers keep you warm

    It's a good idea to layer your clothing by, for example, wearing a T-shirt and a sweater underneath a jacket. If you become too hot, it's always easier to remove a piece of clothing than to add another. On the West Coast, prepare to dress for cool rainy or snowy weather. You will need:

    a warm waterproof coat   ☆ waterproof hats

    an umbrella    ☆ rain boots or snow boots

    Learn more about weather and seasons across Canada. You can also contact Related Links, for example, an immigrant-serving organization in the community where you live for more information about dressing for winter.
