There are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.

    But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little in school. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may have many problems at their schools.

    You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, it may not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.

    What do you think of cats? Some people think very lovely. But not all people love cats. Compared with dogs, cats seem to be very lazy and unfriendly. Besides, cats are not known for acts of selflessness (无私). But maybe we're wrong about them. Don't believe it? Then meet Pippa, a very unusual cat.

    The black-and-white cat was left in a box outside a shop and taken by the British RSPCA to the Jansa family in Whitstable, Kent. They really loved her character (性格) and decided to adopt (收养) it，but they never guessed she'd become a lifesaver.

    Eight-year-old Mia Jansa had diabetes and had become good at testing her blood during the day, as well as having something to eat or drink to bring her blood sugar levels back. But the danger was at night. Mia could easily experience hypoglycemic (低血糖症的) situations when she was asleep, which could cause even death.

    Soon after she was adopted, Pippa went into Mia's bedroom in the middle of the night and woke her up. When the child tested her blood sugar levels, she found they were dangerously low. Ever since, Pippa always visits Mia at night. If she can't get her to wake up, she raises the alarm.

    “Pippa does this of her own accord,” says Mia's mother Laura. “We don't make a request for caring because we don't want to encourage wrong alarms. She gets plenty of hugs. It gives me peace of mind and I know someone else is keeping an eye on Mia.”

    Now the family is so happy that they've chosen to adopt it in the first place.

    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.

    A golf tournament (锦标赛) isn't held every day and thus, as an organizer, you have to put on a great show for those who wait for it.

    Preparations before the Tournament

    An important thing you need to note down at this stage here is that once you start advertising an event, the event has actually begun for the audience. At this stage, you need to decide what you are going to call this event. You should make the name and the advertisement special, so that people will give them a second look. Depending on your economic situation, you need to decide whether you want to hold this event for amateurs or for experts. The next thing is to choose a proper place to hold the tournament.

    Plan of Action during the Event

    While the players are on court, you have to make sure that everything they might need is made available to them. Since golf is a sport that is played in the open, guests should be given drinks from time to time, preferably a drink of their choice. There should also be enough dustbins to keep the court clean. The things the guests need, from extra equipment to drinks, should not be put off for any reason. Announcement of some contests, lucky draws and prizes during the event will add to the entertainment of the tournament. Another one of the successful golf tournament ideas is an auction (拍卖) of some particular things during the game. You can get some equipment signed from the players.

    Post Tournament Necessities

    Now that the tournament is over, you need to keep a small after-party in the form of a dinner. During this party, the guests can actually communicate with the players and congratulate those who won.

    In the far future, robots live on Earth as humans but the population of humans is smaller than a thousand. This is a story of a repair robot R-62.

    One day, a car came to the repair factory and a human stepped out of the car.

    "Wow, a human! I have never seen a real one," said R-62.

    "Humans are quite clever. They're able to do any action they want to. They're even able to harm other human beings or organize wars, which they have been doing a lot in the history. Also they don't even have to follow orders if they don't want to," said another robot T-59 quietly to R-62.

    "How terrible it is! And almost all robots seem afraid of him and don't look at him directly," said R-62.

    The human then sat down and asked if there had been any problems in the last 10 years and he only got a quick answer, "No, sir."

    Then suddenly, R-62 said loudly, "I have one question for you."

    The human said, "Yes", a bit unhappy for not getting "sir".

    "Why do human create so many robots?" asked R-62.

    Silence followed the question and he then said, "I don't need to answer questions from robots!" He then went into his car and drove away quickly.

    "I really don't understand why humans replaced (取代)themselves with robots," asked R-62.

"Because they thought that robots were more advanced(先进的) than humans. They created us to support themselves," answered T-59.

    "But there are so few humans on Earth. What they should do is take away the robots or at least make them stop doing the work which humans are supposed to do," said R-62.

    "I agree. But we can do nothing about it. And now we have to finish repairing this car," said T-59.

    "All right, let's continue."
