Scientists think they have answered a mystery: How some ocean creatures got so huge so quickly.

A few million years ago, the largest whales, averaged about 15 feet long. Then seemingly overnight, one type of whale, the toothless baleen whale(须鲸类)became huge. Modern blue whales get as big as 100 feet. Nicholas Pyenson of the Smithsonian Natural History Museum said, “Why is that?” ”It happened in the glance of an evolutionary eye, which makes it harder to figure out what happened,” said Graham Slater, lead author of the study. Their study has suggested an answer: Ice ages in the last 3 to 5 million years started it, changing the oceans and food supply for whales.

The researchers used fossil records of the smaller whales to create a family tree for baleen whales which include blue whales, humpbacks and right whales. Using computer simulations(模拟)and knowledge about how evolution works, they concluded that when the size changes started, the poles got colder, ice expanded and the water circulation in the oceans changed and winds shifted, Slater and Pyenson said cold water went deep and moved closer to the equator(赤道)and then eventually moved back up with small fish and other small animals that whales eat.

Baleen whale, which have no teeth, feed by eating huge amounts of fish they capture. Toothed whales, like sperm whales (抹香鲸), hunt individual fish, so the ocean chants that made food less evenly spread out didn’t affect them as much. But baleen whales hunt schools of fish.

Olivier Lambert at the Royal Belgian Institute of Natural Sciences calls it “a really convincing situation”. But he said the lack of fossils in certain time periods is an issue. As oceans warm from man-made climate change, the seas will be more like it was when the whales smaller and they will have a more difficult time surviving.

1.What does the author mean by “It happened in the glance of an evolutionary eye” in the second paragraph?

A. The change of baleen whales happened too quickly.

B. The change of baleen whales was too difficult to explore.

C. Researchers paid little attention to the change of baleen whales.

D. Researchers thought the change of baleen whales was unimportant.

2.What played the key role in baleen whales’ becoming huge?

A. Man-made climate change.

B. Its eating a huge amount of fish.

C. The water circulation in the oceans.

D. The increase of food supply for whales.

3.What do we know about sperm whales and blue whales according to the text?

A. Sperm whales eat more food.

B. Blue whaler live much longer.

C. Sperm whales prefer to hunt schools of fish.

D. Blue whales usually swallow schools of fish.

4.What can we infer from the last paragraph?

A. There are no whale fossils now.

B. The whales may become even bigger.

C. Global warming has threatened the whales.

D. Olivier Lamber thinks the study is perfect.

After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf – grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’ s red foxes, and completely drove away the park’ s beavers.

As early as 1966,biologists asked the government to consider reintroducing wolves to Yellowstone Park.They hoped that wolves would be able to control the elk and coyote problems.Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S.Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone.Today,the debate continues over how well the gray wolf is fitting in at Yellowstone.Elk,deer,and coyote populations are down,while beavers and red fores have made a comeback.The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

1.What is the text mainly about?

A. Wildlife research in the United States.

B. Plant diversity in the Yellowstone area.

C. The conflict between farmers and gray wolves.

D. The reintroduction of wolves to Yellowstone Park.

2.What does the underlined word “displaced” in paragraph 2 mean?

A. Tested. B. Separated. C. Forced out. D. Tracked down.

3.What did the disappearance of gray wolves bring about?

A. Damage to local ecology. B. A decline in the park’s income.

C. Preservation of vegetation. D. An increase in the variety of animals.

4.What is the author’s attitude towards the Yellowstone wolf project?

A. Doubtful. B. Positive. C. Disapproving. D. Uncaring.

Summer is the perfect time to relax.As you plan for your trip,here are some tips on how to protect yourself. 1..

Fight against the mosquitoes in the hot spots.

There are many mosquito-borne illnesses in tropical regions,which are traditionally vacation hot spots. Therefore,mosquito repellent(驱蚊剂)that contains DEET should be an essential item in your travel bag.

2..

In lesser-developed countries there is less equipment for clean water and public health.If you can't avoid unhealthful water,make sure you bring along a tea or coffee—making pot that will boil water for you.You'd better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

Always protect your feet.

It's best to wear slippers in the shower,but if you must be barefoot,put a towel down on the floor.3..You should never walk barefoot in any area of a foreign country,including your hotel room.

Be sure to eat safe fruits.

4..They may have been washed in the same water,or wiped with the same rag used to clean work surfaces in kitchens.The best advice is to bring your own peeler(削皮器)so that you know that something clean has been applied to the fruit.

Enjoy the smell of roadside stands,not the food.

Unless the food is piping hot when served,it's best to stay away from roadside stands,no matter how good the smell of the food might be.If you are concerned about whether a restaurant is clean,order the food to go.5..

A.Don't trust the local water

B.Any fruit served fresh may be polluted

C.Look out for any water not served in a bottle

D.The boxes may be cleaner than the plate or fork on the table

E.You should know how to keep yourself away from dirty fruits

F.They are necessary to avoid coming back with a major illness from your trip

G.Parasites(寄生虫)can enter the skin of your feet and travel to different parts of the body
