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.

Big cats have existed on the earth for millions of years, though scientists aren’t sure exactly how long. But a new study indicates that a skull (颅骨) of a snow leopard (豹) relative that was recently unearthed is 4.4 million years old. That makes it the oldest big cat fossil (化石) ever found.

A team of US and Chinese scientists unearthed the skull in Tibet. This creature is not a direct ancestor to big cats, but it is closely related to the snow leopard, study leader Jack Tseng told the Associated Press. The fossil lends evidence to the belief that big cats existed in Asia and spread out from there.

Big cats are at the top of the food chain and have few predators of their own. Big cats include snow leopards, clouded leopards, tigers and lions. Based on genetic judgements, most scientists believe they first existed in Central Asia. But previously, the oldest known big cat fossil was 3.6 million years old and found in Africa.

The new fossil findings were published in the November 13 issue of the science journal Proceedings of the Royal Society B: Biological Sciences. Tseng and his team were fossil hunting in the Himalayas in 2010 when they discovered some bones, including the buried cat skull. The researchers were able to determine its age by studying the surrounding rocks and soil. The skull indicates that the animal was about the size of a clouded leopard, which can grow up to 50 pounds. In 2012, the team returned to unearth more cat bones.

David Polly from Indiana University told the Associated Press that the fossil is “convincingly older than the current record holder”. He added that there could be even older big cat fossils in the Tibetan plateau to uncover.

1.What does the newly unearthed skull prove?

A. Big cats might have their origins in Asia.

B. The oldest fossil is 4.4 million years old.

C. The snow leopard is the oldest big cat.

D. The skull is of big cats’ direct ancestor.

2.What does the underlined word in Paragraph 3 mean?

A. relatives.　　 B. enemies.

C. partners.　　 D. protectors

3.How do the researchers know the skull’s age?

A. By measuring its size and forehead.

B. By examining other bones around it.

C. By studying its chemical composition.

D. By exploring the rocks and soil around it.

4.Where was “the current record holder” in the last paragraph found?

A. Asia.　　 B. Africa.

C. America.　　 D. Australia.

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions.Some believe the air inside many houses may be more dangerous than the air outside.It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired,to suffer eye pain,headache and other problems.Some pollutants(污染物质) can cause breathing disorders,diseases of blood and even cancer.Most scientists agree that every modern house has some kind of indoor pollution.

People have paid more attention to the problem now.It is said that when builders began making houses and offices,they did not waste energy.To do this they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.

As the problem became more serious,scientists began searching for a way to deal with it.They discovered a natural pollution control system for buildinggreen plants.Scientists do not really know how plants control air pollution.They believe that a plant’s leaves absorb(吸收；吸引) or take in the pollutants.In exchange the plant lets out oxygen through its leaves and small organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space.Studies of different plants show that each absorbs different chemicals.So the most effective(有效的) way to clean the air is to use different kinds of plants.Having green plants inside your house can make it prettier and more healthy place.

1.Generally speaking,indoor air pollution may be more harmful than that outside because _______.

A. indoor air pollution can often make people seriously ill

B. man-made building materials give off dangerous gases

C. there may be more harmful gases outside the buildings

D. the flow of air indoors is limited,which is very harmful

2.Some kind of indoor pollution can be found in _______.

A. every modern house　　 B. every old house

C. all kinds of houses　　 D. all kinds of offices

3.The indoor air pollution is caused by _______.

A. the limit of the flow of air between inside and outside

B. the building way that the builders want to save energy

C. the building things that are made of man-made materials

D. the man-made building materials and the limit of air-flow

4.The reason why we should use different kinds of plants to clean the air is that _______.

A. plants can let out all kinds of pollutants indoors

B. plants may take in more oxygen which people need

C. plants can absorb some kinds of harmful indoor chemicals

D. plants can make our houses prettier and more healthy

As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it.

We take fishes from the ocean — millions of kilograms of fish, every year, to feed millions of people. 1. We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates(蒸发). 2. Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them up by simple evaporation. Other gifts from the sea are pearls, sponges and seaweed. Pearls become jewelry. 3. Seaweed becomes food of many kinds— even candy, and ice cream — as well as medicine. Believe it or not, fresh water is another gift from the sea. We cannot drink ocean water. 4. But ocean water becomes fresh water when the salts are removed. In the future，we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. 5. Huge as it is, the ocean cannot hold all the water that we pour into it. Dumping garbage into the ocean is killing off sea life2. Yet as the world population grows, we may need the sea and its gifts more than ever.

We are finally learning that if we destroy our seas, we might also destroy ourselves. Hopefully, it is not too late.

A. Natural sponges become cleaning aids.

B. We pollute the ocean when we use it as a garbage dump.

C. The area of the sea is becoming smaller and smaller.

D. Along with salt, other minerals are left after evaporation.

E. We even use their bones for fertilizer.

F. Some of its contents may cause illness.

G. We take a lot from the ocean and give little to the sea.

Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

“Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

This may not________sit well with________pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don’t have to feed it, you don’t have to walk it, it won’t make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

It’s not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It’s the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn’t need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn’t have a heartbeat might not be a far-fetched dream.

1.What does the underlined phrase “sit well with” means?

A.be refused by B.be beneficial to

C.make a difference to D.receive support from

2.What are the advantages of robot pets?

a. They are plastic and feel smooth.

b. Owners needn’t worry about them when going out.

c. They can help cure allergies(过敏).

d. They save space and costs.

A.ab B.bc

C.bd D.cd

3.We can learn from the passage that___________.

A.Sony is the first company to produce robot pets Aibo.

B.People can develop strong bond(联系、关系) with their robot pets.

C.Rault thinks robot pets still have a long way to go.

D.Robot toys may help people care more about living beings.

4.The passage mainly tells us___________.

A.the advantages of robot toys B.the popularity of robot pets

C.living pets are dying out. D.robot pets are coming.

“White Bikes” on the Road

People in Amsterdam have been enjoying the benefits of cycling for years. The idea began about 50 years ago, and was first known as “white bikes”. Amsterdam is a good city for cycling because it’s _______ and therefore convenient for bikes. There are also plenty of places for bicycle parking and most streets in the city center have a bicycle path.

The group painted hundreds of bicycles white and placed them in many areas around Amsterdam for people to use. Anyone was allowed to take them and use them for short journeys. Wherever someone _______ a journey, they would leave the bike there for someone else to use. Soon after, _______, problems came up and the “white bikes” all _______—thieves took all the bicycles within weeks!

In 1999, the “white bikes” returned to Amsterdam—this time with a computer tracking system to _______ their every move! To take a bicycle, you had to put in a special card. The　　 bikes were parked at special parking places. Thus people who wanted to use them had to take them to another special parking place near their destination and leave them there.
