Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world’s ocean’s food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!
Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt(适应) well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one-third of the 400 shark species are in danger of extinction, largely due to over-fishing. Each year, tens of millions of sharks are caught and killed just for their fins(鳍). The fins are used to make shark fin soup.
Humane Society International (HSI) joined with the Jane Goodall Institute’s Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, “the Price Behind the Taste-----Protect Sharks. Don’t Eat Shark Fins”, was designed to tell people that shark finning is cruel and unnecessary. It’s hoped that the activity will help put an end to the practice.
Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.

Sharks have lived in the world's oceans for millions of years. A shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. These powerful senses help them find their food. 1.
Sharks grow slowly. About forty percent of the different kinds of sharks lay eggs. 2. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.
3. .They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in the ocean do not become too great. This protects the plants and other forms of life that exist in the oceans.
People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased greatly because many parts of a shark are valuable. 4. . Shark liver oil is a popular source of Vitamin. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins.
Sharks are among the oldest animals on Earth. 5. If too many sharks in one area are killed, the group of shark may never return to normal population levels
A. The others give birth to live young.
B. Sharks are important for the health of the world's oceans.
C. This is a threat to other form of life in the ocean.
D. Collectors pay thousands of dollars for the jaws of a shark.
E. Sharks are valuable to us and we can make full use of them.
F. But some sharks are in danger of disappearing from Earth.
G. Sharks eat fish, other sharks, and plants that live in the ocean

Easy floating
If you have ever been swimming in the ocean, you may have noticed that sea water is easier to float in than pool water. Here’s why:
You’ll need
Two clear bowls Food coloring Spoon Salt Two eggs
1. Fill bowls halfway with water.
2. Add 10 tablespoons of salt to one bowl, mix until it dissolves, and then add several drops of color.
3. Carefully put an egg into each bowl of water, and watch what happens.
What happens?
The egg in the plain water sinks. The egg in the salt water floats.
(If the salt water egg does not float well, mix more salt into the bowl. )
The water and salt particles (粒子) in the salt water bowl are closer together than plain water particles are. They press harder against the egg than the plain water particles do and the egg floats.
1.The purpose of the experiment is to explain ________.
A. why the egg floats in the salt water
B. why people float more easily in the sea
C. how we can make the egg float in water
D. how the water and salt particles act together
2.According to the text, if the egg in the salt water doesn’t float, which is the reason?
A. The water is too hot. B. The egg is not fresh.
C. The bowl is too small. D. The salt is not enough.
3.Why does the egg float in the salt water instead of in the plain water?
A. The egg gets more pressure. B. The salt particles press harder.
C. The water particles are closer. D. The food coloring gives a force.

Each year, about 7 million tons of trash (垃圾) is found in the ocean. This trash consists of cigarette ends, medical waste, plastic, mile-long nets, etc... Those items of trash choke (窒息) many species of ocean life so quickly that they eventually become extinct. Ocean pollution harms the earth and animals, and we should stop the problem.
Some other causes of ocean pollution are waste, poisonous chemicals, and the biggest cause is littering (乱丢垃圾). How do these items end up in the ocean? Waste flows through rivers and drains (下水道) directly to the ocean, so ocean pollution continues to step up. The estimated amount of ocean pollution that floated in the sea in 2012 was 288 million tons. This huge number continues to increase by 4% each year. That means 11, 520, 000 tons of trash increase each year. Imagine the future of our ocean. Will there be any room to swim? Also 80% of the ocean is composed of plastic: plastic bottles, plastic bags, and some plastic toys.
How can ocean pollution be solved? Use fabric bags instead of plastic bags. This would reduce the plastic pollution in the ocean. Also for the waste water problem, we could use waste water treatment system. Lastly using renewable energy sources such as wind power or solar power would limit offshore drilling.
If we don’t stop the causes of ocean pollution, water temperatures will continue to rise and ocean life will become endangered. Please be mindful that what we do affects the people around us, the animals around us, and the habitats around us. So will you pay attention to this problem or wait for the next generation to?
1.What leads to the ocean pollution worst?
A.Cigarette ends. B.Littering.
C.Medical waste. D.Plastic.
2.How many ways are mentioned to solve the problem in Paragraph 3?
A.3 B.4
C.5 D.6
3.What’s the author’s purpose in writing the text?
A.To introduce what’s ocean pollution.
B.To make a survey about ocean pollution.
C.To make us know more about ocean pollution.
D.To call on everyone to fight against ocean pollution.
4.What is the best title for the text?

In summer, millions of people will head for the beach．And while the ocean can be a great place to swim and play, it may also be useful in another way．Some scientists think that waves could help make electricity．
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”
Scientists are working on using that energy to make electricity．
Most waves are created when winds blow across the ocean．“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said．“Waves are one of nature’s ways of picking up energy and then sending it off on a journey．”
When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) ．The turbine can then power an electrical generator (发电机) ．
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．
The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal．
Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．
Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Besides, wave power would get in the way of fishing and boat traffic．
With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
1.We can infer from the passage that ______．
A. finding new energy sources like wave energy is important
B. wave energy is a resource that will never run out and is used all over the world
C. wave power is perfect for creating energy around the world
D. wave power doesn’t create any pollution
2.The underlined word “drawbacks” probably means ______．
A. regrets B. adventures C. disadvantages D. difficulties
3.What can be the best title for the passage?
A. How to Get Electricity by Waves．
B. A Huge Resource of Energy．

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino(厄尔尼诺). The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
1.El Nino is known as ___.
A. the changing of the weather in southern Africa
B. the warming of waters in the Pacific Ocean
C. the weather which brings drought(旱灾) to Africa
D. the weather phenomenon (现象)that brings heavy rains to Africa
2.Scientists study El Nino in order that ___.
A. they can provide a kind of early warning to the place that will suffer from drought
B. they can tell why Zimbabwe has little or no rain
C. they can do some research work in this field.
D. they can put all this information into their computers.
3.Which of the following is TRUE according to the passage?
A. Nature is the name of the article written recently by the scientists.
B. Three scientists from the USA work on this subject.
C. Southern Africa suffered a serious drought and many people died from hunger.
D. El Nino has something to do with Zimbabwe’s poor crops.
4.What’s the best title for this passage?
A. Appearance of El Nino is Predictable（可预测的） B. Drought in Zimbabwe
C. Early Warning System D. Weather in Africa
