Pigs are always considered dirty animals because they roll in mud.But in fact they prefer  being quite clean.They cover themselves with mud to help stay cool.During cooler weather,  they prefer to stay clean.So do elephants, who also cover themselves in dust or mud to keep cool.When they find a place with clean water they will take a bath,using their long noses to give  themselves—or each other—a nice shower
Some animals use dust to get clean.Chinchillas (南美洲栗鼠) have very fine fur. They don’t like to take water baths because water is not warm enough for them.So, instead, they roll  around in fine dust.The dust helps to keep their fur and skin dry.This protects them from disease
Usually, a small bird is a light meal for a crocodile.But when a crocodile wants its teeth  cleaned.it lies on the ground with its mouth open.The crocodile bird goes in and picks out any  parasites(寄生虫)between the crocodile’s teeth or under its tongue.The crocodile gets its mouth cleaned,and the crocodile bird gets dinner.
You wouldn’t think fish would need baths.But some undersea parasites live under the  fish’s skin.“Cleaner” fish,like the wrasse(隆头鱼),help take them away.The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business.The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food.

Sina Weibo, one of the country’s most popular micro-blogging sites, has launched a paid service. For a 10 yuan ($ l.57) monthly fee, users get a membership on their Sina Weibo accounts.
According to Xu Yuanyuan, a member of the marketing team at Sina, the move is to guarantee a more convenient and safer environment for users. But despite the company’s efforts to increase income, it seems that most of its 300 million users still prefer the free version.
The premium membership (高级会员) plans ,announced by the company on Monday, brought about negative comments from its users .
“The current service is good enough for me”, said a Beijing-based micro-blogger. “I don’t really need those value-added services and it might be a waste of money. I might consider paying for it if some more features are added.”
Dong Xu, an analyst with consulting firm Analysis International, said that Sina shouldn’t expect a great increase in income brought by the new services. The free services are enough for most users, Dong said. “The company has been making attempts at different profit models since last year. A potential source of income could be gaming. Games and advertisements are so far the two biggest sources of income.” she said.
Other micro-blogging service providers have not yet followed suit. Fang Gang, vice-president of rival Sohu, said via e-mail on Tuesday that Sohu’s micro-blogging service will never charge users. “It’s good news for us. Users can come to our website if they have to pay for services (at Sina).” Fang said.

The chimp didn’t feel well. She fell over, ignoring the other wild chimps. Finally, the sick chimp crawled over to a bush, picked some leaves and swallowed them. By the next afternoon, the chimp was as good as new!
Biologists watching the chimp were surprised. Somehow, the plant had cured the chimp! Did the chimp know the plant would make her feel better? Or was it just a lucky accident?
Many scientists don’t think it has anything to do with luck. They’re discovering that some animals seem to use plants to cure themselves. And these animals are leading scientists to new plants that could cure humans!
Dr. Richard Wrangham, an anthropologist at Harvard University, agrees that animals may know something we don’t know about forest plants.
Wrangham got to know chimps and their diets while studying them for three years in Tanzania. “You must know a lot about an animal’s feeding habits to know what it doesn’t consider food,” Wrangham explains. Every morning, he saw that most chimps ate fruit near their nests. Later on, they ate on leaves.
When he noticed chimps eating the leaves of a plant they usually ignored, Wrangham thought something interesting was going on---especially when he saw that they’d sometimes walk for 20 minutes to find the plant. Another strange thing that caught his eye was how they ate the bitter leaves.
“They swallowed the leaves whole,” explains Wrangham, noting that chimps usually chew their food well. “They seemed to rub(摩擦)the leaves around the roofs of their mouths. They closed their eyes, wrinkled their noses and swallowed slowly. ”
Wrangham wondered what could be so good about something tasting so bad. He had a chemist analyze the leaves. He discovered that the leaves contain a red oil that kills different viruses(病毒). Later tests showed that the oil might even fight cancer and the AIDS virus!
Why don’t the chimps chew the leaves? “Rubbing the leaves between the tongue and the inside of the mouth might allow the chemicals to enter the bloodstream directly,” he suggests, “instead of going to the stomach, where they might get destroyed by acids. The chimps seem to know what they’re doing.”
We can learn from the passage that _________.

A.chemicals in plants help cure animals
B.chimps cure themselves by chewing plants
C.scientists live with chimps to study their diets
D.Dr. Wrangham knows a lot about forest plants

How can Dr. Wrangham tell which plants are medicine for chimps?

A.By talking with the biologists.
B.By analyzing the chimps’ favorite food.
C.By studying the chimps’ feeding habits.
D.By comparing other scientists’ discoveries.

The author wrote the passage to ___________.

A.present a finding B.test a theory
C.provide a solution D.describe an experiment

What does the passage mainly talk about?

A.Forest plants. B.Animal doctors.
C.Chimp’s diets. D.A cure for cancer.

It does not matter who wins. We are told that from day one. Usually, that statement is followed by some remark about being a loser. If we do not care who wins, then why do we compete? Fun, experience, the chance to meet new people --- these are the reasons we try to outdo each other.
People will compete over anything. Every Christmas, my neighbors and I have a little Christmas light competition. It is heaven for the electric company, but I think we give Will Rogers Airport a scare. It is bright enough to land a plane in our front yards. I admit that last year my neighbors won, but only because they bought every strand of lights Wal-Mart had before I could get there.
Personal competitions are great, but we get a little carried away. I cannot stand to see coaches shout at kids playing sports. Who cares if someone messes up and the other team advances?
I’m tired of people competing just to win. It happens not only in sports, but in music competitions, too. People auditioning(试音)for chair placement in certain bands can get really unfriendly. This year I did not audition for a certain band, but I went to auditions anyway. This was the first time I actually had the opportunity to comprehend the whole picture.
Other times I’ve been the person who was nervous and anxious. This time, I sat back and observed everyone else. I came to the realization that the people who aren’t so good are terrified of the good people, and the good people are scared stiff that the bad people have taken lessons and can now show them up. Unless a person is on the outside looking in, I don’t think anyone realizes this.
Maybe competing is human nature, but we shouldn’t let it influence our judgment. Being disrespectful to opponents(对手), letting competition become our life, and becoming so involved that we close ourselves off from friends and family is not the meaning of competition.
A little competition is healthy, so it shouldn’t hurt anyone. If it does, someone somewhere needs to back off, find the good thing hidden inside, and try it again. Winning isn’t everything, and losing isn’t the end of the world.
The author mentions his competition with his neighbors to __________.

A.make excuses for his failure
B.express his concern about the airport
C.imply his neighbor cheated in the competition
D.show people really care about the result of competition

A.the author failed the audition

C.it is coaches who always mess up the match

A.Competition for the job is fierce.
B.Winning or losing is none of people’s concern.
C.Competition is healthy, but it can get out of hand.
D.The disadvantages of competition outweigh the benefits.

My name is Pablo. I think I’m a lucky guy. I have a good family, and we live in a nice neighborhood in Puerto Vallarta, Mexico. People travel here from many countries for their vacations. We have beautiful beaches, hotels, restaurants, shopping and sports.
However, in my beautiful hometown, there are also very poor neighborhoods. These areas are crowded and have a lot of crime. Life is terrible for many of the children in these areas. Some don’t really have a childhood because they’re homeless and live on the streets. They don’t have education. They don’t have enough food. Many use drugs or have diseases or mental problems.
Last year, I came back to Puerto Vallarta from my university in Mexico City. I spent one year as a volunteer with an organization called Outreach International. They have several programs. I volunteered for one program to help street children.
I worked in a home for street children (all boys, at this one). At this home, the boys have a place to sleep and three meals daily. The home keeps the boys off the streets. It shows them another way of life. As a volunteer, I helped to prepare meals. I taught games---such as basketball, football and art. I helped the kids with their homework. These kids can be fun. They have a lot of energy, but they’re also really tough. Their hardships on the streets make them strong and not always “sweet little children.”
At this boys’ home, I met two other volunteers---Brian from Canada and Greg from Australia. In many ways, we were very similar. We were the same age, came from good homes and had a good education. They were both college students, like me. We became very good friends. Now, we email each other.
It was the best---and most difficult---year of my life. I learned a lot that year.
