In 1945，6 planes and 17 men disappeared without a sign, all in one day. This was Flight 19. Flight 19's captain was Lieutenant Charles Taylor. Flight 19 was a usual flight. It took off at about 2:10 p.m. from Miami. The weather was very normal on that December 5th of 1945. A message was received at 4：00 p．m.that told about pilot Taylor not knowing the way to go because his compass(指南针) was running around and around.

    After that，it was never heard from again.While searching for it，a search plane was also lost.The search for the both continued until December 10th of that same year.None of the things from Flight 19's planes，or from the search plane，was ever found.It is one of the most infamous disappearances. Searching for Flight 19 lasted five days，and covered 380，000 square miles. Dr. Kripke suggests that the accident happened because of a vortex(涡流).

    Say the words “reality TV” and the show that comes into most people's minds is Big Brother{#blank#}1{#/blank#} There have been varieties in more than seventy countries. The basic form is simple: put a group of strangers into a house, record everything they do and watch how they live together.

    {#blank#}2{#/blank#}A similar show, the Real World, was broadcast in 1992 on MTV. But the form really became popular with the success of Big Brother, and it was copied again and again{#blank#}3{#/blank#} For examples, in wife Swap, a mother went to live with a family of strangers and tried to run their home.

    I have had a lot of problems recently. Firstly, I'm not happy in class. I'm so shy that I'm afraid of speaking in class. Secondly, I argued with my best friend. I'm very worried because I have few friends. I don't want to lose her. Thirdly, I feel nervous when the midterm exams are coming. And sometimes I even can't sleep well at night.

    Yesterday, my mother took me to the doctor. I told the doctor my problems and 他给我一些建议. He asked me to make more friendly friends and play games in my free time, so that I would not be so shy. He also said, "If you don't want to lose your best friend, you should talk with her. Tell her ________ you think." Because I couldn't sleep well, he asked me to eat some food that was good for sleep. And he asked me to relax. I'm trying to follow his advice. I think I will get better soon.

    I've always wanted to try rock climbing, but never had the time or money for it. But I've discovered a way to experience the thrill(兴奋，紧张)of climbing rock, without climbing real rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer！Indoor climbers don't climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms, schools and camps have one.

    You can climb indoors at any time of the year, no matter how the weather is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for the rush(刺激感)they get. When I stand at the foot of the wall and look up. I'm always scared, But once I start climbing, fear changes to determination. With my heart pounding(怦怦地跳), I reach the top and look down. I can't stop grinning(咧嘴笑). I did it!

    Indoor climbing is a great workout. Climbing uses muscles that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

    Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls your climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip. But make sure your partner know how to use this equipment. And if you are a first-time climber, get some instruction before you begin.

    Many people believe that not only wetness, but also light and dirty things are the greatest enemies of stamps. People protect their stamps in several different ways.

    In fact, we should never touch the stamps with our hands. This avoids moving dirty things onto them. Stamp tweezers (镊子) should be used in all conditions.

    Stamps are printed things. The colour will slowly disappear if they are put in the light for a long time. So we should not put stamps in the light for long. Direct sunlight must be avoided as well.

    Wetness is an important problem for stamps. Some collectors will put stamps in separate plastic bags. However, it is possible that some stamps have taken in some water from the air before they are put into the plastic bags. Stamps become yellow easily and rapidly after they take in wet air. To protect the stamps, some people also put the stamps into a special room which has a machine to keep the air cool and dry. However, not many people can afford that.

    To keep stamps, stamp collectors usually put them under plastic covers. It is a common and simple way. This helps because the plastic cover keeps the stamps off the wet air. It also stops the fingers from touching the stamps.

    Some collectors prefer to store stamps inside a plastic box with desiccants (干燥剂). However, we should take care not to let the stamps touch the desiccants. On top of that, don't take your stamps out on a wet day.
