Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash（垃圾） there that scientists are now concerned that if we don't clean it up, we may all be in mortal （致命的）danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning things that no longer served any useful purpose in space.
It is estimated that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide（碰撞） with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

It seems hard to watch someone yawn（打哈欠） and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force.
Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don’t develop this deeply rooted behavior until around age four, the study found. Kids with autism (自闭症) are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect.
"Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did.
"The fact that autistic kids don’t do it might mean they’re really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others’," she added. "Autistic people never seem to understand that."
Like infectious （有感染力的）laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group.
1.What does the new study suggest, according to the first two paragraphs?
A. Yawning is a form of communication.
B. It is easy to stop yawning when you see others yawn.
C. Children follow others in yawning just after they are born.
D. Yawning has some mysterious force which is related to God.
2.According to Molly Helt, _________.
A. humans differ from animals because they communicate with others
B. yawning is a kind of emotional connection among humans
C. emotions are infectious, but yawning is not
D. yawning helps clear ears on planes
3.Which of the following is NOT true about yawning?
A. It is natural to yawn back if people around you yawn.
B. Some kids are too young to yawn after others.
C. Yawning can be used to test children’s development.
D. Kids with autism yawn easily when others yawn.
4.The author implies in the last paragraph that ________.
A. yawning is different from infectious laughter and crying in theory
B. it is bad manners to yawn on some social occasions
C. the more you yawn, the happier you will be
D. yawning can make people feel relaxed
The Swiss army knife is a popular device that is recognized all over the world. In Switzerland, there is a saying that every good Swiss citizen has one in his or her pocket. But the knife had poor beginnings.
In the late nineteenth century, the Swiss army issued（发给） its soldiers a gun that required a special screwdriver（螺丝刀） to take it apart and clean it. At the same time, canned food was becoming common in the army. Swiss generals decided to issue each soldier a standard knife to serve both as a screwdriver and a can opener.
It was a lifesaver for Swiss knife makers, who were struggling to compete with cheaper German imports. In 1884, Carl Elsener, head of the Swiss knife manufacturer（maker） Victorinox, seized that opportunity with both hands, and designed a soldier's knife that the army loved. It was a simple knife with one big blade(刀片), a can opener, and a screwdriver.
A few years after the soldier's knife was issued, the "Schweizer Offizier Messer," or Swiss Officer's Knife, came on the market. Interestingly, the Officer's Knife was never given to those serving in the army. The Swiss army purchasers considered the new model with a corkscrew（瓶塞钻） for opening wine not "essential for survival," so officers had to buy this new model by themselves. But its special multi-functional design later launched(发行) the knife as a global brand. After the Second World War, a great number of American soldiers were stationed in Europe. And as they could buy the Swiss army knife at shops on army bases, they bought huge quantities of them. However, it seems that "Schweizer Offizier Messer" was too difficult for them to say, so they just called it the Swiss army knife, and that is the name it is now known by all over the world.

The day of my holiday arrived, but I wasn’t looking forward to it. I had little money and had only been able to afford to stay with my Aunt Rosa in Spain. So, I wasn’t really excited as I knew exactly what it was going to be like: lots of noisy cousins , and Aunt Rosa begging me to take her for a ride.
After I had checked in, I made my way slowly to the departure gate. As I was waiting to board the plane, I kept thinking about my ideal holiday destination: Jamaica, with its long, sandy beaches and crystal clear water.
As soon as the plane took off, I fell fast asleep and only woke to the sound of the announcement: “Ladies and gentlemen, please fasten you seat belts, as we will shortly be landing in Kingston.” I froze in my seat. Was I dreaming? Kingston? Jamaica? I had boarded the wrong plane!
Immediately after the plane landed, I explained the situation to the authorities. It seems there were also three other passengers heading for Spain. Apparently it had been the airline’s fault, since the flight numbers for Spain and Jamaica were exactly the same! Therefore, with no flight back to London for a week, the airline had no choice but to pay for our stay.
So there I was, lying on the beach, enjoying the music and the marvelous food of Jamaica! As for Aunt Rosa, I suppose she just had to live without me!

[1]Although known as an extraordinarily successful businessman, Warren Buffet comes off as a pretty ordinary person.
[2]Looking back on his childhood, one can see how serious he was about making money. Buffet used to go door-to-door and sell soda pop. Later, he also worked at his grandfather’s grocery store. At the ripe age of 11, Buffet bought his first stock(股票). When his family moved to Washington D.C., Buffet became a paperboy for The Washington Post. While still in school, he was making $175 a month, a full-time wage for many young men.
[3]From the beginning, Buffet made his fortune from investing. He started with all the money that he had made from selling pop, delivering papers and so on. Between 1950 and l956, he grew his $9, 800 to $14, 000．From there, he organized investment partnerships with his family and friends, and then gradually drew in more people through very attractive terms.
[4]Buffet applied to Harvard Business School but , making it to be one of the worst admission decisions in Harvard history. The outcome ended up affecting Buffet’s life deeply, for he ended up attending Columbia Business School, where he studied under Benjamin Graham, the father of securities analysis who provided the foundation for Buffet’s grand success.
[5]Buffet is a person of habit—same house, same office, same city. He doesn’t collect houses or cars or works of art, and he hates companies that waste money on such goods. Instead, he has established the Buffet Foundation, with a detailed plan on how to invest his money more wisely to society.
