It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats faster when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

He holds numerous F1 world records including most race victories, fastest laps, and most races won in a single season. According to the Formula One website, he is “statistically the greatest driver the sport has ever seen”. Also notable are his contributions to charity, during the peak of his career he has given away more than 50 million Euros to a variety of charity organizations, most to help children around the world.

Americans plan parties for many reasons. As in other cultures, many Americans attend parties for weddings and religious or national holidays. But some parties are especially American. For example, a group of neighbors may gather on their street to eat food, play music and visit with one another. This is called a block party. A woman might invite a group of women to a party called a baby shower for a friend who is about to give birth. Guests bring presents for the new baby.
Americans also attend tailgate parties. A tailgate is the back end of a truck or other vehicle that opens down. The tailgate parties are a big part of sports culture in the United States. Friends bring food and drink to a sports event. They eat together in the parking area of the sports stadium.
Birthday parties are also very popular. Many parents organize a party for their child around a theme. Birthday parties usually include gifts and a birthday cake with candles. In many parts of the United States, cupcakes have become a popular replacement for cakes.
Birthday parties can be low cost or very costly. Some parents take their children’s birthday parties very seriously, even when the child is too young to fully understand the celebration.
One group of parents started a website called Birthdays Without Pressure. They decided that some parents were under too much social pressure to plan costly parties for their children. The group sees this movement as an example of America’s culture of “too much stuff”. The group’s website gives suggestions on how to keep birthday celebrations simple, meaningful and fun without spending a lot of money.

Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studiedfor the test or who were the true winners of a game.
Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test --- unless the person cheats again.
Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.
Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can’t pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn’t a good idea.
If you were sick or upset about something the night before and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.
A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions(解决办法) together. Talking about these problems and working them out will be better than cheating.The author thinks that when kids cheat in class,________.
| A．it does harm to their heath |

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pet in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.The word shelter in paragraph one means:
| A．warm clothes | B．a hiding place | C．proper temperature | D．diet food |

Mark Thompson, the BBC’s director general, is expected to announce on Thursday that the BBC will quit its entire west London home -- possibly selling the land to Chelsea football club -- as part of main plans that will see more staff moved out of the capital to Salford and elsewhere．
The move is at the heart of the BBC’s long-awaiting cost-cutting strategy（策略）which will see nearly 2,000 more jobs going at the public broadcaster, and some original programming，such as daytime shows on BBC2, eliminated to save money．
Several thousand people are employed at the west London sites，including Thompson himself and the bosses of all the BBC’s television channels．The employees are expected to be relocated（重新安排）to Broadcasting House in central London, Salford, or elsewhere．
The BBC has been broadcasting at various locations in the Shepherd’s Bush area since moving into Lime Grove in 1949．It then switched to the Television Centre in 1960，and more modern offices at nearby White City．But it is now open to selling the site, and the broadcaster has had talks about attracting Premier League clubs Chelsea or Queen’s Park Rangers as buyers．Both clubs are looking for new homes．
Earlier leaks（透露）suggest that the BBC will seek to cut spending on sports where the corporation has already decided to share coverage of Formula 1 with Sky TV -- and imports，such as Mad Men and The Killing．BBC4 is expected to focus on “arts and archive（档案）”, but Thompson has long ruled out closing any channels or radio stations．BBC1 and Radio 4 will be protected，but there are expected to be some cuts to local radio programs, which will see stations share shows outside breakfast and drive-time hours．
The corporation is already committed to remove TV Centre by 2015, but because parts of the building are listed, the football clubs have expressed an interest in the BBC’s White City offices instead，which could be knocked down. The White City building is where Thompson and the broadcaster's commercial division, BBC Worldwide, are based．
BBC sources say the 2,500 job losses being proposed（提议）include the 650 cuts to the World Service already announced, with up to l,000 coming from BBC News．It is understood that some staff who have only just made the move to Salford could see their jobs at risk. Salford is now home to Radio5 Live, children’s programs such as Blue Peter, and sports output including Match of the Day．Why is the BBC planning to quit its west London home?
| A．The BBC wants to earn more money． |
| B．The BBC would like to support British football sport． |
| C．The BBC is planning to save money for new programs． |
| D．The BBC has to cut down its cost． |
The underlined word “eliminated” in the second paragraph means“_________”．
| A．set aside | B．cut out | C．sold out | D．put on |
What will happen if the BBC moves its home ?
| A．Some original programmes will be adjusted． |
| B．All the BBC staff will have to work outside London． |
| C．More people will be employed for new programs． |
| D．Some TV channels or radio stations will be closed． |
From the passage，we can learn that ________．
| A．the BBC will cover Formula 1 on its own as usual |
| B．the football clubs are likely to buy some of the BBC’s offices |
| C．the BBC’s commercial division will be open to selling the sites |
