We don't have beds in the space shuttle（航天飞机），but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. 

    On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane; the shuttle's computers and the engineers at the Control Office do that. If anything goes wrong, the computers ring a warning bell and the engineers call us on the radio. 

    On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes,we wear black sleep mask（眼罩）.

    It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float in a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax（放松）for a while, listening to music and watching the Earth go by under me. 

    When I'm in space I don't need as much sleep as I do on Earth. Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping.

    On my way home from work one day in 1994, I stopped at a supermarket for shopping. I was behind two customers. The person checking out was a young mother with her little girl. As the clerk was scanning （扫描）the things she had chosen, the young lady was carefully counting her money, worried. After the last thing was scanned, the clerk told the young mother the total.

    The young mother's expression turned to embarrassment （尴尬）as she realized she did not have enough money. She started to see which things to put back, and nervously looked behind her, knowing she was holding up the line. I was smiling and trying to look sympathetic （同情）I had been in situations where I did not have enough money plenty of times myself. Finally, the young mother gave something back to the clerk, and asked for new total. 

    At that moment, the woman in front of me asked the clerk to wait a moment. She took out $5 and handed it to the clerk to pay what the young mother was short of, When the clerk tried to give the woman the fifty cents change, she pointed to the little girl and told the clerk to give it to her. The little girl smiled and ran to one of the machines to spend the money. Naturally, the young mother was thankful and said so. The woman smiled and told her she was welcome.

    I will never forget the look on that little girl's face-not when she was given the money. But when she realized that a perfect stranger cared enough to help them. From the way she looked at the woman, you could tell that she learned something valuable that day; Some people do care.

    That woman taught me several things with that one little deed. There are many situations in which we can help other people. It doesn't take much money. A few dollars to someone like me was something quite different to that mother.

     A zoo is a place where animals are kept and displayed (展示) to the public. Some people argue that a zoo need not be a place for animal display alone, and may also include raising animal species (物种) which are becoming less and less.
     Animal rights groups are divided on the matter of keeping animals in zoos—with some in favor of this practice, and others calling for a ban (禁令) . The most important reason that those in favor of this practice put forward is that it offers protection for animals. For those species which are fighting for their life, zoos are the best places where they get plenty of food, water and medical care when needed.
     Those who are against the practice argue that the idea of"displaying animals to the public"is itself a strong enough reason for banning. They further add that the practice of using animals for our own selfish gains cannot be a good reason under the excuse of protection. The treatment of animals in these zoos is yet another big worry, with quite a few reports about ill-treatment (虐待) of animals once in a while.
     It's very difficult to come up with a clear idea on whether it is right to keep animals in zoos or not. It is true that the animals are protected in these places as they don't get into conflict with humans. But, at the same time, one has to admit that keeping them in zoos equals a disrespect for nature. These animals are born to live in the wild, and we should accept this fact. 

    Very soon a computer will be able to teach you English. It will also be able to translate any language for you too. It's just one more incredible result of the development of microprocessors-those tiny parts of a computer commonly known as "silicon chips". So give up going to classes，stop buying more textbooks and relax. In a couple of years you won't need the international language of English.
    Already Texas instruments in the United States are developing an electronic translation machine. Imagine a Spanish secretary，for example，who wants to type a letter from the boss to a business man in Sweden. All he or she will have to do is this ：first type the letter will appear on another television screen in Stockholm in perfect Swedish.
    And that's not all. Soon a computer will be able to teach you English，if you really want to learn the language. You'll sit in front of a television screen and practice endless structures. The computer will tell you when you are correct and when you are wrong. It will even talk to you because the silicon chips can change electrical impulses into sounds. And clever programmers can predict the responses you，the learner，are likely to make.
    So think of it. You will be able to teach yourself at your own pace. You will waste very little time，and you can work at home. And if after all that，you still can't speak English you can always use the translating machine. In a few years，therefore，perhaps there will be no need for BBC Modern English，or BBC English by Radio programs—no more textbooks or teachers of English. Instead of buying an exciting new textbook，the computer will ask you to replace it with microprocessor one thousand nine hundred and eighty-four. Fast，reliable and efficient language learning and translating facilities will be available to you. Think of that no more tears or embarrassing moments. One little problem is that a computer can’t laugh yet-but the scientists are working on it. Happy learning！

     Most 11-year-olds are just happy to have finished their first year of middle school. However, Tom is not like most kids. He did not go to elementary (小学) , middle or high school but went straight to college at the young age of eight.
     While Tom's parents knew he was smart, they had never imagined putting him in college this young. However, when they tried to send him to a private (私立的) school at the age of six, he was turned down, because he was so smart that the school was afraid he would feel dull.
     It turns out the school was right. After homeschooling the young boy for two years, the parents realized that he was ready for some real high-level courses. They came to East Los Angeles College, who agreed to take him in. However, until he proved himself, he could take only two courses-math and music.
     Tom did not disappoint. He got A's in both and hasn't looked back since. Last week, he graduated as a top student. In fact, the young boy was so smart that he helped his fellow math students, some of whom were 10 years older than him.
     While the world may cheer him as a genius (天才), his parents think he is just a normal boy who plays football and watches movies for children.

     Nowadays everyone is so much trying to keep fit that sometimes they miss the fact there are times when they should not be exercising at all. Here you can find real reasons to stop training for a while and do not feel sorry for your laziness.
     When you are ill
     Do not exercise if you are not feeling well, even if it is just a cold. Workout can hurt your immune system (系统) and lengthen illness. As a result, you will spend more time away from the physical activity. Training while being ill is also a main cause of other injuries since it is more difficult to focus on (专心于) what you are doing when you feel bad.
     When you have not had enough recovering time
     Do not rush back to your normal workout habit after you have been ill. Starting to train too early is likely to lead to a return of your symptoms (症状) . When you do decide to go back to the sports ground, be sure to start your exercise slowly and with care. Even one week or so off your usual exercise can make a difference.
     When you are tired out
     There sometimes are days when you do not feel like going to the sports ground, and sometimes your body might be telling you to take a break. It will do you a lot of good to have a day off from your fitness classes. Go home, have a healthy meal and do not feel sorry for not being at the sports ground.
     Remember that sometimes you just need to relax.

     A number of children with special educational needs are home educated when schools cannot meet their needs.
     As a parent, you must make sure that your child receives a full-time education suitable to their age and ability from the age of five. You do not need to be a good teacher and your child does not have to follow the National Curriculum (国家课程标准) or take national tests. There is no money directly from the central government for parents who decide to educate their children at home, but the local (当地的) governments do provide guidance for parents, including free National Curriculum materials.
     Local governments should keep an eye on the parents who educate their children at home to make sure that a suitable education is being provided. You can provide evidence (证据) that your child is receiving a suitable education by writing a report and providing some of your child's work. You can also invite a local government officer to your home or meet him outside the home, with or without your child being present—officers have no right to get to your home without permission.

     "Most children carry their phone in their back pocket, and when someone reaches for it, in my mind they're reaching for a gun, "said Della Fave, a spokesman (发言人) for New Jersey police.
     Della Fave shared a photo of the iPhone case (外壳) that he found on a social website (网页) . In the photo, a model stands with her phone in her back pocket, and the case looks like a gun.
     Della Fave said, "If a child draws the phone with the gun-like case before policemen, the first thing they're going to see as it's coming up is a gun. This doesn't seem like a good idea at all to a policeman.
     The phone case is sold online by various sellers at prices from about $5 to $49 and comes in several different colors. "The case is popular. That's why we sell it. If you have the case, you can play games of shooting at parties," said the Trend Shop. "Don't worry. You can't actually shoot anyone! "
     A policeman gave a few words of advice, "I would NOT suggest buying this kind of phone case, which was designed to look like a gun.
     It is not clear who makes the case. "If it's on the web, then it's out there somewhere；that's the bottom line," said Della Fave.

     Did your child's brain become smaller last summer? Probably not, according to a study by Dr. Harris Cooper, professor at the University of Missouri-Columbia. The study found that when students return to school after a long summer vacation, they've lost one to three months worth of learning.
     This is more harmful for math than it is for reading. "All students lose math skills," says Cooper.
     It may be because kids (小孩) have more chances to practice reading than math. Middle-class children actually learn more in reading than lower-income students over the summer. Cooper feels that this results from the variety of activities that many middle-class kids take part in over the summer, such as camping (野营) and trips.
     "Parents can help their kids keep educational skills," says Cooper. He suggests the following tips to have a learning-filled summer.
     1. Keep lots of books around and make regular trips to the library. Most libraries offer special summer events for kids.
     2. Think about what your kids may be learning next year when you plan the family vacation. Talk with teachers to find out what they"ll be covering in class.
     3. Keep math in mind. Since kids lose more math skills than anything else over the summer, try to do some special planning to find math-related activities.
     4. Consider summer school. Struggling kids can get a lot of different kinds of help from summer school programs. Summer school can also enrich and quicken learning in areas where kids show a special interest.
     Remember to keep it fun! You don't want to make your kids unhappy with learning during the summer break.

​     Effective teamwork is key to the success of a business. Teamwork helps tasks get completed quickly and efficiently (高效地) . However, poor teamwork can hinder a business' success and make operations much more difficult. Four parts of teamwork can make it effective and lead to business success.

     Effective Communication (沟通)
     Without effective communication, a team will be weak. When a team has open and honest communication, a lot more will be achieved. Communication makes sure that everyone listens to one another's ideas and will help them express their thoughts and feelings. Good communication also helps put together a clear plan of action.
     Different Skills
     The way the team is made up of plays a major role in how well the group works as a team. It is necessary that people with different skills be paired together so that they can make use of one another's knowledge and skills. For example, in a team, there should be a few people who are good at planning, one or two key leaders and several experts in various subjects.
     Strong Leadership
     Leadership is important in a team. A leader is needed to settle disagreements, set goals and keep the team on track. A good leader can lead without being bossy, achieve goals by encouraging the team and stepping in when necessary, and make suggestions for improvements.
     Passion (激情)
     A team without passion will get nowhere. If any member of the team does not have the passion to get the job done and do it well, he or she will become less and less interested in the duties and bring the rest of the team down.
