A press report stating that Microsoft has restarted talks to buy Yahoo's search business for 20 billion U. S. dollars. "It has no basis in fact," the San Francisco Chronicle said on Monday.

The Times of London reported on Sunday that the deal under discussion would put former AOL CEO Jonathan Miller and Ross Levinsohn, a former president of Fox Interactive Media, in charge of Yahoo. The report also said executives (管理人員) at both companies had agreed to the broad terms of a deal.

In fact, there are no current talks between the two companies. The Chronicle quoted an executive at one of the firms who requested his name to be kept secret as saying. Furthermore, the 20-billion-dollar price mentioned in the Times of London article for Yahoo's search business appears questionable given that the market capitalization (資本總額) for all of Yahoo is 16 billion dollars, said The Chronicle.

Yahoo and Microsoft had had on-again, off-again talks over several months earlier this year about a 47. 5-billion-dollar takeover, and later a proposal focused only on Yahoo's search business. Discussions regarding both plans collapsed without an agreement.

Microsoft CEO Steve Ballmer has said repeatedly that he is no longer interested in buying all of Yahoo, but that he is open to some sort of partnership involving their respective search businesses.

Brad Williams, a Yahoo spokesman, said Sunday "We don't comment on rumors." Frank Shaw, a Microsoft spokesman, declined to comment.

Yahoo's shares have plummeted since Microsoft withdrew its 33-dollar-a-share acquisition offer earlier this year, leaving people to think that discussions would eventually be restarted. Yahoo's shares closed Friday at 11. 51 dollars, nearly one-third of the original offer.

1. From this passage, we can know that ______.

  A. Microsoft has given up buying all of Yahoo but its search business 

  B. Microsoft has already taken over the whole company of Yahoo

  C. the market capitalization for all of Yahoo is over $ 20 billion

  D. the market capitalization for all of Microsoft is only $ 6 billion

2. What is the author trying to convince readers of in the third paragraph?

  A. Yahoo and Microsoft are talking about takeover.

B. Microsoft is buying Yahoo’s search businesses for $ 20 billion.

C. Yahoo would like to sell its search businesses to another company.

D. There are no current talks between Yahoo and Microsoft.

3. What does the underlined word “plummet” in the passage most probably mean?

  A. develop rapidly      B. increase quickly      C. fall quickly     D. keep balanced

4. You can find this passage most probably in ______ .

  A. an entertainment website       B. an economical newspaper

  C. a sports magazine              D. a biological dictionary

BROOKSVILLE — It’s the time of year again, when young bears are on their own for the first time. And that means more sightings where bears usually aren’t supposed to be.

This weekend, a 258-pound black bear took a brief tour of Brooksville, with police and firefighters chasing.

Another black bear, weighing just 100 pounds, was spotted Saturday, crossing busy U. S. 19 near a retirement community in Spring Hill. Several other bear reports have come from Citrus County.

"It is really difficult for the younger bears to find their own land around here, " said Niki Everitt, bear hot line director for the Gulf Coast Conservancy.

Brooksville’s bear first was spotted late Thursday crossing State Road 50, headed toward Tom Varn Park. Police and firefighters tracked the bear through the park and the Brooksville Quarry golf course.

The bear then wounded down the middle of Broad Street before being surrounded near Luigi’s Pizza. An official with the Florida Game and Fresh Water Fish Commission came with a tranquilizer spear(加入鎮(zhèn)靜劑的矛).planning to stick the bear by hand. "The guy saw the size of the bear and figured that wasn’t a great idea, "said Capt. Frank Phillips of the Brooksville Fire Department.

Emergency officials waited until a tranquilizer gun was brought from Land O’ Lakes. The bear then got a free ride to the Chassahowitzka Wildlife Management Area.

It is not unusual for bears to move into living areas this time of year, experts say. Mothers give their male baby bears the boot once the youngsters are 2 years old. With living areas growing, the young bears keep finding smaller and smaller areas in which they can set up their own land.

"They’ re trying to find a land of their own, where they won ‘t get beat up, " said Lt. Rip Stalvey, a game commission spokesman.

Everitt said people should not be too concerned about the recent bear sightings, since" we have never had a bear attack in Florida."

Black bears mainly eat the tender and fresh leaves of Sabal palms, as well as acorns and berries. Recent weeks of dry weather likely have reduced their food supply.

"If we don’t get some relief soon," Everitt said," we’re probably going to see a lot more of it."

1. What’s the main idea of this passage?

A. Bear sightings in living areas worry people.

B. Policemen try hard to get the bears controlled.

C. People take up too much land from bears.

D. ears come out to disturb people’s lives.

2. Which is true according to the passage?

A. The 100-pound bear was caught near Luigi’s Pizza.

B The Gulf Coast Conservancy makes bears homeless.

C. Brooksville’s bear was too large to be caught by hand.

D. Bears frequently visit humans’ living areas.

3. Bear sightings can usually be expected ______.

A. in the cold season                    B. in the warm season

C. near lakes or rivers                   D. near Luigi’s Pizza

4. The underlined phrase "give their male baby bears the boot" means______.

A. make them wear the boots             B. find new homes for them

C. drive them away from home            D. keep them in safe places

LONDON----Here’s a new warning from health experts: Sitting is deadly.

     Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be bad for your health. And it doesn’t matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it occurs. Several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.

　　In an editorial published this week in the British Journal of Sports Medicine, Elin EkblomBak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.

　　While health officials have issued guidelines recommending minimum amounts of physical activity, they haven’t suggested people try to limit how much time they spend in a seated position.

　　"After four hours of sitting, the body starts to send harmful signals," Ekblom-Bak said. She explained that genes regulating(調(diào)節(jié)) the amount of glucose（葡萄糖） and fat in the body start to shut down.

　　Even for people who exercise, spending long periods of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day — but still spend a lot of time sitting — might get more benefit if that exercise were spread across the day, rather than in a single bout.（一回）

　　Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, independently of whether or not they exercised.

　　"We don’t have enough evidence yet to say how much sitting is bad," said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, who led the Canadian study. "But it seems the more you can get up and interrupt this sedentary behavior, the better."

　　Figures from a U.S. survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.

　　Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible to offset those effects.

　　"People should keep exercising because that has a lot of benefits," Ekblom-Bak said. "But when they’re in the office, they should try to interrupt sitting as often as possible," she said.

1.What is the best title for the text?

A. Not Sitting Too Much While Working      B. How To Avoid Sitting Too Much

C. Sitting Too Much Could Be Deadly          D. More And More People Sit Too Much

2.According to the research,______________.

A. the more time you spend in exercising in a single bout, the healthier you will be.

B. those who often sit too much are sure to grow fat or suffer from a heart attack.

C. regular exercise is effective to get rid of the side effect of sitting too much.

D. you had better not sit for more than four hours in a single bout.

3.How does the danger of sitting too much affect the human body?

A. It results in a higher death risk.

B. It increases glucose and fat in the body.

C. It makes a person unable to exercise long enough in a day.

D. It causes the gene to fail to balance the glucose and fat in the body.

4.In the opinion of Ekblom-Bak, you’d better have a rest in the office by________.

A. sending your friends e-mails           

B. having a walk around your office

C. chatting online or playing computer games 

D. listening to music with your head on the desk.

The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.

Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(覓食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don't know whether this is due to an increase in the number of nests or because we have started to monitor(監(jiān)控)nesting beaches more closely.

The green turtle is the largest hard­shelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.

Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.

In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.

1.The main idea of the passage is to tell us________.

A．something about an endangered animal

B．how green turtles got extinct

C．how heavy a green turtle is

D．how long a green turtle can live

2.Which of the following is NOT a reason why green turtles are endangered?

A．Humans catch them to get profit.

B．They lose their nests.

C．They have fewer places to find food.

D．People like to keep them as pets.

3.According to the passage, the green turtle________.

A．can reach 100 cm in length in 17 years

B．lives in the sea and grows very slowly

C．lives only in Florida and on the Pacific coast of Mexico

D．can grow from 30 to 75 cm in 17 years in southern Florida

4.Why is it hard for us to know the number of green turtles?

A．Because it is difficult for us to be close to them.

B．Because we have limited knowledge about them.

C．Because we haven't measured their growth rates.

D．Because they grow too slowly.
