Cats are well-known for the way they keep themselves clean by licking , but other animals have their own ways to stay clean as well. And tidiness can be important for their survival. Even cockroaches have to keep their feelers clean to help them into food. Many animals in the wild, such as deer, wolves and bears, have an automatic cleaning system. Insects like to attach themselves to animals to feed on the skin or blood. These parasites can be unhealthy. But their "host" animals are constantly dropping skin and fur by a natural process. They also like to rub up against trees or rocks to comfort themselves, and this removes additional skin and fur. Along with old fur goes the dirt and parasites living in the fur. While these animals may sometimes take a bath when they enter or cross a river or lake, they don't need the water to stay clean. They don't get sweaty, because they don't have sweat glands all over their bodies the way people do. Growing new skin and fur is enough to keep them clean. Some animals and birds use dust to get clean. Chinchillas, a kind of small animal that lives in the mountains of South America, have a very fine fur. (They are raised for their fur, in fact.) If they took water baths, they might get too cold. So, instead, they roll around in fine dust, raising quite a cloud as they "bathe". The dust helps to keep their fur and skin dry. This protects them from bacteria and parasites that enjoy warm and wet places. And the fine dust doesn't stick in their fur for long. It falls off or blows away. As for lions and tigers, their rough tongues act like combs and can remove dirt and loose fur. Why is it important for them to stay clean and smooth? It helps them stay cool in very hot summer or feel warm in cold winter. Question: What's the main idea of this passage? Options: A: Animals enjoy living in a clean environment. B: Animals fight against parasites in different ways. C: Unlike people, animals hate staying in water. D: For animals, cleanliness is a survival skill.

Article: Many people don't realize the importance of music education in the schools today.A new study showed, however, music education is extremely important. In college, music education is one of the largest programs.Teachers have to learn general education materials and techniques. They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more.At the same time, much of our culture and tradition is absorbed in music. Music plays a very important role in our education. Music helps with math and science. Students learn to count, and how to multiply and divide.Students also use science to help them discover what sounds good together and what doesn't.Students also need science to understand something called the "overtone series", which is about how music is produced by vibration and why. Students learn a lot about languages through music.Many songs are written in other languages, including ancient ones.Students must learn to translate these works to understand what they are singing about. A song is likely to be a famous short work set to music; so students are exposed to that very often while singing. Students learn a huge amount of cooperation of body parts through music, so parts of the body can work better together.Students must use motor skills in order to play an instrument.Singers and wind players must learn breath control and be in good shape to play. Students learn about art. Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music. Music education also brings higher thinking to our children.It allows them to think about complex patterns.Students have to be aware of what every other musician does at every time.In that way, it develops cooperation, as well.They tend to develop more ability for learning. As one can see, music is very important to education. Question: As to the benefits from music, which of the following is NOT included in the passage? Options: A: Calculation. B: Language study. C: Relaxation. D: Cooperation of body parts.
C

Q: Read the article and select the best answer. Article: Computer people talk a lot about the need for other people to become "computer-literate". But not all experts agree that this is a good idea. One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer, David does not see _ that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them "people-literate". David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do. They find out. The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don't have to learn computer terms , but the experts have to explain in plain language. The computers are becoming "people-literate". Question: We can infer from the text that "computer-literate" means _ . Options: A: being able to afford a computer B: being able to write computer programs C: working with the computer and finding out the value D: understanding the computer and knowing how to use it
A: D

Q: Read the article and select the best answer. Article: The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland. Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation. JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers." For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident. Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water. JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables." The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean. JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of _ . So the concentration of radioactivity in the seawater would still be quite low." Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says. Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry. A new United Nations... Question: According to the passage which of the following is not TRUE ? Options: A: Water people drink ,food and vegetables people eat may be polluted by nuclear radiation . B: Japan is the only country to have had atomic bombs dropped on it. C: You can go to www.unsv.com. to get the latest news . D: The nuclear accident in Japan is the worst in the nuclear power industry.
