Is it difficult for you to get up in the morning? Do you sometimes oversleep？ Are you often late for work or school? Yes? Then Hiroyuki Sugiyama of Japan has a (an) 1 bed for you. Hiroyuki's bed will get you up in the morning! Here is how it 2 .
The bed 3 an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays 4 music or other pleasant sounds. The tape recorder in Hiroyuki's bed plays a recording of his girlfriend. She whispers in a sweet 5 , "Wake up, darling, please." A few minutes later, a second recording 6 . The sound recording can be loud music or 7 sounds. Hiroyuki hears a recording of his boss shouts, "Wake up immediately, 8 you'll be late!"
If you don't get up 9 the second recording, you will be sorry! A mechanical "foot" is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few 10 minutes. What! You're still in bed! Slowly the 11 of the bed rises higher and higher. The foot of the bed goes lower and lower. 12 the bed is vertical (垂直的). You slide off the bed and onto the floor. You are out of bed and 13
Hiroyuki made his bed because he wanted to 14 a contest. He works for Honda Motor Company. Once every two years Honda has a contest for its 200,000 employees ---"All-Honda Idea Contest".

Most people believe they don’t have much imagination. They are 11 . Everyone has imagination, but most of us, once we become adults, forget how to 12 it. Creativity isn’t always 13 with great works of art or ideas. People at work and in their free time 14 think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
Making connections. This technique involves taking 15 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words 16 with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 17 to the job you have to do. So imagine you want to buy a friend an original 18 ; you could buy him tickets to match or take him out for the night.
NO limits! Imagine that normal limitations don’t 19 . You have as much time /space / money, etc. as you want. Think about your goal and the new 20 . If your goal is to learn to ski, 21 , you can now practise skiing every day of your life (because you have the time and the money). Now 22 this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a 23 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the 24 in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their 25 . The best fishermen think like fish!

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It's all very good to ban human cloning but scientists should be allowed to 47
research. If they don't, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.

With high pace of modern society, more and more people get stressed and feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and doesn’t require any specially attention. The second kind, situational loneliness, is a natural result of a particular situation ―for example, when a family problem appears, the time a loved one dies, or when they move to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type, it usually lasts for more than two years and has no specific cause. People in this case have problems socializing and can not become close to others. Unfortunately, many such people think there is little or nothing they can do to improve their condition.
Psychologists are trying to find ways to help habitually lonely people for two reasons: They are unhappy and unable to socialize and there is a connection between habitual loneliness and serious illness such as heart disease. While temporary and situational loneliness can be normal, healthy part of life, habitual loneliness can be a very sad, and sometimes dangerous condition.

In 1989 an international law was passed to 25 people putting waste into the sea. It is now against the 26 to put anything into the sea nearby. Such rubbish as plastics may not be thrown 27 the sea anywhere. Other waste may be put into the sea, either 19 or more than 40 kilometers from land, 28 the nature of the materials.
The 29 of dealing with waste has become so great that several international organizations have been 30 to protect the world and control pollution.

Butterfly’s wings
One day a small opening appeared on a cocoon(茧), a man sat and watched for the butterfly for several hours as it was struggling to 1 its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten 2 it could and it could go no further. So the man decided to 3 the butterfly: he took a pair of scissors and 4 the remaining part of the cocoon. The butterfly then 5 easily.
But it has a swollen(肿胀的) body and 6 wings. The man continued to 7 the butterfly because he expected that, at any moment, the 8 would enlarge and expand to be able to support the body, which would 9 in time. Neither happened! 10, the butterfly spent the rest of its life 11 around with a swollen body and small, shriveled(褶皱的) wings. It 12 was able to fly. What the man did in his 13 and haste(匆忙)did no good to the butterfly. He didn’t know the 14 cocoon and the struggle 15 for the butterfly to get through the tiny 16 were the natural way of forcing fluid from the body of the butterfly into its wings 17 it would be ready for flight once it achieved its 18 from the cocoon.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite ____53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize 54 young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

Every human being, 36 what he is doing, gives off body heat. The usual problem is 37 dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the 38 problem — how to collect body heat. They have designed a collection system which utilizes 39 body heat, but the heat given off by such objects 40 light bulbs and refrigerators as well. The system works so well 41 no conventional fuel is needed 42 the campus’ six buildings comfortable.
Some parts of most modern buildings — theatres and offices 43 classrooms — are more than amply heated by people and lights and sometimes must be air-conditioned 44 in winter. The technique of 45 heat and redistributing it is 46 “heat recover”. A few modern buildings recover 47 , but the university’s system is the first to recover heat 48 some buildings and re-use it in 49 . Along the way, Pitt has learned a great deal about some of its heat producers. The 50 a student studies, the more heat his body 51 . Male students emit more heat than 52 students, and the larger a student, the more heat he 53 .

The team was __7__ looking at how animals and birds make eggshells but suddenly made their surprising __8__. The big question now is where chickens came from. The _9__ is from dinosaurs.
The research team said eggshells are one of nature’s most __10__ creations. Professor John Harding from the team told reporters: “Understanding how chickens make eggshells is fascinating in itself, but it can also be __11__ in designing new materials.” Eggshells are very lightweight but incredibly strong. Even the most up-to-date materials __12__ by the world’s top engineers can not produce anything as __13__ as an eggshell.

It is interesting how NASA(美国航天航空局) chose their astronauts for landing them on the moon. They chose men 36 the ages of twenty and thirty-five. There were about fifty of them. Some were 37 air pilots, and 38 were scientists with two or three degrees. NASA telephoned each man they were going to choose, told him the plans and the 39 they might get into. They then asked him if he was willing to be trained as an astronaut, “How could any man 40 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous 41 most exciting.”
The health and physical condition of the people was, 42 , very necessary. Only those in very good health and physical condition were 43 .
While being trained to be astronauts, they went through many 44 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary 45 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the 46 of the moon. They were all 47 to fly in helicopters. There helicopters landed straight down to give them some 48 of the way the spaceship would actually land on the 49 . They were also taught the known facts about the 50 in space.
