IT'S a mystery that has puzzled scientists. Five years ago, researchers found an area in the Atlantic Ocean seabed, where a part of the Earth's outer layer, or crust(地壳), is missing. A thick layer of dark green rock, which is usually found deep inside the planet, lies exposed.
The crust, mantle(地幔) and core(地核) are the main layers that make up the planet. The mantle rests between the crust and the core.
Last month, a team of 12 British scientists set off on a six-week trip to study the hole in the crust.
The hole is about 4,800 meters below sea level and is believed to be more than 48,000 meters long and more than 48,000 meters wide. Scientists think that there are other nearby gaps. "It is like a window into the interior (内部) of the Earth," says scientist Bramley Murton, who is part of the research team.
The site where the hole is located is part of a ridge (山脉) of undersea volcanoes. There, two of the plates that make up the Earth's surface meet. The plates are always moving. When the plates move away from each other, lava rushes up from the mantle to fill the gap and form a new crust. But this did not happen in the area where the hole is located.
The hole is giving researchers a good opportunity to study what's below the Earth's surface. The team will use a special robotic tool to film the area and get samples of the exposed mantle. They hope to study everything from the chemistry of the oceans to how the Earth's surface behaves under the sea. What's the title for the passage?

Cheerleading is the fastest growing girls' sport, yet more than half of Americans do not believe it is a sport. Actually, competitive cheerleading is a sport.
A sport is a “physical activity against/with an opponent, governed by rules and conditions under which a winner is declared, and the primary purpose of the competition is a comparison of the relative skills of the participants. "Because cheerleading follows these guidelines, it is a sport.
Competitive cheerleading includes lots of physical activities. Like gymnasts, cheerleaders must learn to tumble (翻滚) . They perform lifts and tosses. This is where the "flied' are thrown in the air, held by "bases" in different positions that require strength and cooperation with other teammates.
Just as basketball and football have guidelines for competitive play, so does competitive cheerleading. The whole routine has to be completed in less than 3 minutes and 15 seconds and the cheerleaders are required to stay within a certain area.
Competitive cheerleaders' goal is to be the best. Just like gymnasts, they are awarded points for difficulty, creativity and sharpness. The more difficult a mount, the sharper the motions, the better the score. Cheerleading is a team sport so without cooperation, first place is out of reach.
Cheerleading is the number-one cause of serious sports injuries to women. Emergency room visits for cheerleading are five times the number of those for any other sport, partially because they do not wear protective gear. While many athletes are equipped with hip pads or helmets, smiling cheerleaders are tossed into the air and spiral down into the arms of trusted teammates. The fliersmust remain tight at all times so that their bases can catch them safely. Also, because cheerleading is not yet recognized as a sport by many schools, neither proper matting nor high enough ceilings are provided to ensure safety. Instead, the girls use whatever space is available. More recognition of competitive cheerleading as a sport would decrease the number of injuries.
So why do many Americans not think cheerleading is a sport? Some people argue that cheerleaders are just "flirts in skirts" with their only job to entertain the crowd, but cheerleaders today work just as hard as other athletes.
Hopefully, cheerleading will become as well-known a sport as football and basketball, and even appear in the Olympics since cheerleaders are just as athletic and physically fit as those involved in the more accepted sports.What does the underlined word "bases" in Paragraph 3 refer to?
A.Strength and cooperation. |
B.Lifts and tosses. |
C.Supporting teammates. |
D.Physical activities |
Gymnasts are mentioned in the passage to _
A. explain the dangers of cheerleading |

It can be learned from the passage that cheerleading
A.is a good sport for all people |
B.lacks necessary guidelines to follow |
C.is more than a form of entertainment |
D.enjoys greater popularity than other sports |
This passage is written mainly to

Being bored can encourage people's creativity-partly to escape the horrible, frustrated. And meaningless feeling of boredom-recent studies find. It could even be true at work.
Psychologists at the University of Central Lancashire had participants copy numbers out of the telephone book for 15 minutes,while others went straight into a standard creativity task.
Both groups were asked to come up with as many different uses as they could for a plastic cup. The group that felt more bored came up with more uses.
Dr. Sandi Mann, one of the study's authors said. " Boredom at work has always been seen as
something to he removed. hut perhaps we should be welcoming it in order to encourage our creativity. What we want LO do next is to see what the practical implications of this finding are. Do people who are bored at work become more creative in other areas of their work-or do they go homeand write novels?"
In a later study, Dr. Sandi Mann found that creativity was reduced when people were still bored but didn't have the chance to daydream.
While we tend to think of boredom as something; that certainly leads to trouble-drinking, gambling. and antisocial behavior, this research suggests differer possibilities.
More than anything, the feeling of boredom is a 8trong signal that we are stuck in some kind of rut and we need to seek out new goals. In the study above, this research led participants to new ideas.
Usually people will do anything to avoid being bored. as it's such an aversive experience. But creative people, like writers, sometimes talk ahout seeking out boredom.
Here is the comedy writer Graham Linehan talking about boredom Lo The Cuardian. "I have to use all these programs that cut off the Internet,force me to be bored, because being bored is an essential part of writing, and the Internet has made it very hard to be bored. The creative process requires a period of boredom ,of being stuck. That's actually a very uncomfortable period that a lot of people mistake for writer's block, but it's actually just part of a long process. "
So, when you start to feel bored , instead of g7ancing at your smartphone.,try being bored for a bit. Who knows what creative thought might come of it?From the study of Dr. Sandi Mann, we can learn that__.
A.boring tasks make people creative |
B.daydreaming may increase creativity |
C.plastic cups can be used very creatively |
D.copying numbers might be very interesting |
The underlined word "aversive" in Paragraph 8 probably means _

According to Craham Linehan..
A.glancing at a smartphone is a solulion. |
B.he is forced to feel bored by the Internet |

D.being stuck for a period benefits him a lot |
What is the author's attitude towards boredom?

I may not be the wisest person on this planet. but I will tell you a little secret to happiness: Help other,, and live life. It is that simple. Just help a friend study for a test, or volunteer at a nursing home . I learned this after a long, hard search.
I was feeling really down because my long4ime friend had died. Then I started a six-week volunteering at a nursing home all day every Saturday. My routine was to serve the meal and clean up. After that, I would wait for the head nurse to tell me what to do.
One day I was told to go to Room 117 to make sure the patient was all righL. In the room I found a boy of eight sitting in his bed watching a movie. I was shocked to see a child in this seemingly forgotten nursing home for the old. He was so small and weak that you had to look closely to find him. He motioned for me to sit down. I grabbed his medical chart from which later I found out he had a terminal illness.
We started to talk, and I found out that his family rarely visited, and all he did ever7 day was watch TV. I wanted to cry for him, and for my lost friend. As we talked, he had a smile on his face, and I asked him why.
"The entire two hours I've been here you've never lost that smile. With this horrible disease, how do you still manage to stay happy?"
He thought for a moment, and then said that too many people are dead even before they die.
They walk around feeling that God has cursed (诅咒) them and that they have nothing to live for.
The boy said that he would not be like that. He wakes every morning thankful to see another sunrise. He keeps his window open so that he can smell the flowers and feel the heat of the sun. He also said that he has hope.
"Too many people haven't seen much of that around here," he said," Life is full of hope and we need to live life before it is gone. "
I don’t know what happened to him. I assume he passed away, but his lesson lives on. I now wake up and live each day to the fullest. The key to life is not money or fame, but the lessons we learn from it.The nursing home in the passage is mainly for _
A.the elderly | B.the homeless |
C.the disabled | D.the abandoned |
The boy stayed happy mainly due to.
A.wonderful TV programs |
B.his positive attitude |
C.good medical condition |
D.others' encouragement |
The writer participated in the volunteering job in order to .
A.find out the secret |
B.search for help |
C.enrich experiences |
D.get out of sadness |
What would be the best title for the passage?
