Bacteria are an annoying problem for astronauts. The microorganisms（微生物） from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overcoming this very tiny big problem? It's turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.
HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon's students have been studying ways to kill bacteria in zero gravity, and they think they're close to a solution（解决方案）. "We don't give the students any breaks. They have to do it just like NASA engineers," says Florence Gold, a project manager.
"There are no tests," Gordon says. "There is no graded homework. There almost are no grades, other than 'Are you working towards your goal?' Basically, it's 'I've got to produce this product and then, at the end of year, present it to NASA.' Engineers come and really do an in-person review, and…it's not a very nice thing at time. It's a hard business review of your product."
Gordon says the HUNCH program has an impact（影响） on college admissions and practical life skills. "These kids are so absorbed in their studies that I just sit back. I don't teach." And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.

At the beginning of my 8:00 a.m. class one Monday at UNLV（拉斯维加斯内华达大学）, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been very good. The young man then proceeded to ask me why I always seemed to be so cheerful.
His question reminded me of something I’d read somewhere before: “Every morning when you get up, you have a choice about how you want to approach life that day,” I said to the young man. “I choose to be cheerful.”
“Let me give you an example,” I continued. “In addition to teaching here at UNLV, I also teach out at the community college in Henderson. One day a few weeks ago I drove to Henderson. I exited the freeway and turned onto College Drive. But just then my car died. I tried to start it again, but the engine wouldn’t turn over. So I put my flashers on, grabbed my books, and marched down the road to the college.”
“As soon as I got there, the secretary in the Provost’s office asked me what had happened. ‘This is my lucky day’, I replied, smiling.”
“Your car breaks down and today is your lucky day?” She was puzzled, “What do you mean?”
“I live seventeen miles from here. I replied. My car could have broken down anywhere along the freeway. It didn’t. Instead, it broke down in the perfect place: off the freeway, within walking distance of here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class. If my car was meant to break down today, it couldn’t have been arranged in a more convenient fashion.”If you want to be cheerful you should ___________.
| A．try to succeed in doing everything | B．try to please your boss every day |
| C．earn a lot of money by working | D．choose to be cheerful every day |
The underlined phrase “turn over” in the third paragraph means “________”

According to this passage we can infer that the teacher’s car broke down ____.
| A．near UNLV | B．along the highway |
| C．near Henderson | D．at the community college |
Which one of the following is TRUE?
| A．The teacher taught not only at UNLV but also at the community college. |
| B．That was the teacher’s lucky day because the teacher liked walking. |
| C．The teacher always hoped that the car would break down often. |
| D．The young man was sad because his car broke down. |
Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．
The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses． So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none． However, a change in food is one of the main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains． We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.
But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.
| A．Stone Age people lived a simple life. B．But today, we enjoy eating a lot of these. C．In that case, they would live much healthier. D．Ancient people also got lots of physical exercise. E．These new sicknesses were not known in ancient times. F．People today probably don't want to live like our ancestors. G．Modern people used to suffer from "diseases of civilization". |
Man has always wanted to fly. Some of the greatest men in history have thought about the problem. One of these, for example, was the great Italian artist, Leonardo da Vinci. In the sixteenth century he made designs for machines that could fly. But they were never built.,
Throughout history, other less famous men have wanted to fly. An example was a man in England 800years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into the air from a tall building. He did not fly very far. He fell to the ground and broke every bone in his body.
The first real step took place in France in 1783. Two brothers, the Mongolfiers, made a very large “hot air balloon”. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year, the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted 8 minutes and that the animals landed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about 8 kilometers. Leonardo da Vinci .

Some people are pessimistic(悲观的)when they think about the future. They say that, a hundred years from now, we will have used up most of the earths resources. We will have made our seas so dirty that we will not be able to eat fish from them. There will be so many people in the world that we will have to use all the countryside for housing; there will be no farmland left.
Other people have a different idea about the future. In their view, the city of the future will be a huge pyramid-shaped(金字塔形的) building, which will be floating on the surface of the sea. About 5,000 families will live there, and there will also be schools, shops in it.
In a hundred years’ time, people will not need to use oil. They will heat their homes with power from the sun.
Think of space. Perhaps a station will be set up on the moon; people will be able to visit the moon as tourists. They may even spend their holidays in space, travelling from planet to planet.
What an interesting picture!
Many people don't think about the future. “I don't care. I’ll be dead. ”they say. But it is our duty to care because the world of a hundred years’ time will be the world of our children’s and their children after them. How many viewpoints are discussed here about the future?
