Sharks have lived in the oceans for over 450 million years. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.

Sharks range in size from the 0.1 meter long dwarf-dog shark to the 18-metre long whale shark — the world’s biggest fish. The whale shark, like two other large shark species — the basking shark and the megamouth shark — are harmless to people because they feed on plants and small aquatic animals.

Sharks have extremely sensitive sense organs. Some sharks can detect the scent(气味) of decaying fish or blood even when it is diluted(稀释) to only one part per million parts of seawater. They can probably hear underwater sounds that originate as far as 3 kilometers away and can tell the direction from which underwater sounds are coming.

Sharks are key predators(肉食动物) in the world’s oceans, helping control the numbers of many other ocean predators. Without sharks, the oceans would be overcrowded with dead and dying fish.

Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which makes a profit for the sellers. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring.

Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of sharks injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.

If you are a typical ocean-goer, your chances of being killed by an unprovoked(无缘无故的) attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than by a shark.

Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.

Sharks are among the few animals in the world that almost never get cancer and eye cataracts. Understanding why can help us improve human health. Chemicals extracted from shark cartilage(软骨) have killed cancerous tumors in laboratory animals, and these chemicals may someday help prolong our life.

Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

1.Which statement best expresses the main idea of the article?

A. There are many different species of sharks, but only a few of them are dangerous to humans.

B. Sharks are important to the ocean ecosystem and they are a valuable resource for humans.

C. Although some sharks are dangerous to humans, they can help save human lives.

D. Sharks always eat small fishes and they are an essential part of the world’s oceans.

2.Which question is NOT answered in the article?

A. How long does a shark live?

B. How many people are killed by sharks each year?

C. Why are sharks important in medical research?

D. What do humans kill sharks for?

3.It can be inferred from the passage that ______________.

A. movies have given people the wrong impression of sharks

B. most sharks are dangerous to humans

C. sharks will attack anyone who is wearing black

D. it is very likely that ocean-goers will be killed by a shark

There are more species of beetles than any other form of life. About 380 000 species of beetles are known to exist, and more are discovered all the time. There are several theories about why there are so many beetles, but fossils evidence shows that beetle species die out less than other animals, Beetle species exist in such huge number because beetles are true survivors. They refuse to die out.

One of the reasons beetles survive so well is their body design. Most beetle species have two pairs of wings. The front pair of a beetle’s wings are hard and thick. They are not used for flying. These protect the back set of wings and the beetle’s stomach. Instead, some species of beetles have lost the ability to fly, but they are still equipped with front wings. The wings protect the beetle’s soft parts from harm. These features help protect beetles, which makes them less likely to die out if they are faced with new predators (捕食性动物).

Beetles can also eat a wide range of foods. Beetle species live all over the world, and they have many different types of food available to them. Most beetles are omnivores. That means they eat both plants and animals. Their mixed diets help beetles adapt to many different habitats. Over the course of time, food sources, like certain plants and animals, do not exist anymore. Others spring up. The beetle survives because it can find something to eat, no matter what.

Finally, beetles are good at moving quickly over long distance. Any change in an animal’s environment can be dangerous to it. For example, many species died out during the Ice Age, when Earth’s temperature dropped for a long time. However, some species can avoid dangerous environment changes by moving to a new place. Research shows that beetles respond quickly to shifts in temperature. They can move to safer environments.

Beetles’ bodies and habits help give them an edge over other creatures. They are unlikely to die out. As a result, beetles make up nearly one quarter of all animal species. There are more types of beetles on Earth than there are types of plants. Some types of beetles that exist today were around during the Permian period of history, 284 million years ago. Beetles, clearly, are here to stay.

1.What is important about a beetle’s front wings?

A.They are used to catch the prey.

B.They enable the beetle to fly.

C.They help the beetle move quickly.

D.They protect the soft body parts.

2.How do beetles respond to changes of habitats?

A.They are adaptable to the food change.

B.They can change their body temperature.

C.They are adaptable to the freezing cold weather.

D.They can use their wings to fight against the cold.

3.What is the most probable title of the passage?

A.The Ice Age affected the beetles

B.Different habitats affected the beetles

C.Beetles: the six-legged survivors

D.Beetles: the unique predators

Most American students go to traditional public schools. There are about 88, 000 public schools all over the US. Some students attend charter schools.

Charter schools are self­ governing. Certain companies operate some charter schools. They are similar in some ways to traditional public schools. They receive tax money just as other public schools do. Charter schools must prove to local or state governments that their students are learning. These governments provide the schools with the agreement called a charter that permits them to operate.

Charter schools are different because they do not have to obey most laws that govern traditional public schools. Each school can choose its own goals and decide what to teach and how to teach them in their own way. Class size is usually smaller than in traditional public schools.

The government strongly supports charter schools as a way to re­organize public schools, which are failing to educate students. But some education unions are against charter schools. One teachers' union has just released the results of the first national study, which compared the progress of students in both traditional schools and charter schools.

The results of the study show that charter school students performed worse on math and reading tests than the students in traditional public schools.

Some experts say the study is not fair because students in charter schools have more problems than students in traditional schools. Other education experts say the study results would make charter school officials realize that they should help their students make greater progress .

1.If a company wants to operate a charter school, it must ________.

A. try new methods of teaching

B. get the government's permission

C. obey the local and state laws

D. prove its management ability

2.What's the government's attitude toward charter schools?

A. Doubtful.　　 B. Unclear.

C. Satisfied.　　 D. Supportive.

3.What can we learn from the text?

A. More students choose to attend charter schools.

B. Charter schools are better than traditional schools.

C. Students in charter schools are well educated.

D. People have different opinions about charter schools.

4.What might be the best title for the text?

A. Charter schools in America　　 B. Public schools in America

C. The government in America　　 D. Education in America

Around the world, there are about 7,000 National Parks. Most of them cover huge areas of land where nobody lives. However, the National Parks in England include places where people live and work, as well as wild areas where there are few human activities.

The National Parks in England are called “England’s Breathing Spaces” because they are places where people can go to be in the open air, away from the dirt and noise of cities. They provide wonderful scenes of mountains, woods, grasslands and wetlands. And there are plenty of activities to do in all of the National Parks in England. Visitors can walk or ride bikes for fun. Many of the parks put on activities for families.

Every year there are about 110 million visitors to the parks, bringing many benefits（益处）to the areas. At the same time, it creates problems too. First, life can be difficult for local people. Car parks and roads are too crowded. Gift shops and cafes take the place of many everyday shops. Even house prices in some areas can become too high. Besides, country roads can be damaged, for too many people walk, cycle or ride horses on them. Roads can be rebuilt, but then they look less natural. Another big problem to the National Parks is litter. In the parks it is a danger to wild animals. Broken glass can also cause fires by focusing the rays of the sun. Such fires in wild places can be out of control.

　　　 ? All National Parks in England are making more rules, which tell people how to take good care of their environment. If these rules are followed, the National Parks will be well kept and continue to give pleasure to many people for a very long time.

1.Visitors to the National Parks in England can 　　　　　　　 .

A.give food to wild animals B.drive cars on the grasslands

C.enjoy fresh air and peaceful time D.have fun farming with local people

2.The third paragraph mainly tells us　　　　　　　　 .

A.the problems of the National Parks B.the pollution caused by visitors

C.the development of the National Parks D.the benefits brought by visitors

3.Which of the following is the best sentence to fill the blank in Paragraph 4?

A.What can people get B.How can people help

C.What are the National Parks like D.How are the National Parks set up

4.The passage is probably taken from the　　　　　　　 part of a magazine.
