What weighs 3500 pounds(1600kg)and lived 60 million years ago?Are you thinking of
dinosaurs?Guess again!You don,t have to go to a museum to see these creatures.They are alive
and swimming in the warm coastal waters of Florida.
Manatees(海牛)have lived a peaceful existence in the warm waters of Florida for 60
million years.However,they are now an endangered species.This means that if humans don,t do
something to save them,they will soon go the way of dinosaurs.
Humans have made life very difficult for manatees.One big danger that humans have
introduced is the speedboat.Because manatees are mammals.they need to come to the surface to breathe about every 5 to 6 minutes.This means that they are in constant danger of being caught in the propellers(螺旋桨)of speedboats.And boating aceidents are the greatest cause of death for them.
Manatees are in extra danger when they are in their sleeping or“torpor”state.They still
have to come to the surface for the air,but sometimes they are too sleepy to avoid the danger of approaching boats.
Another danger for manatees is the pollution that humans produce.Due to human pollution,
a deadly plant called red tide had increased greatly in the Gulf of Mexico.The plant,or algae,
t11riVes(繁茂)on pollution.It wiped out nearly 20 percent of the total manatee population on
earth.
Humans can help to save manatees。The government has established boating speed limits to
give the manatees.a chance to escape approaching speedlsoats.Everyone can help by cutting
down on waste and pollution to protect the waters for the manatees.
One famous singer,Jimmy Buffet,has helped save the manatees.He co-founded the Save the Manatee Club(SMC).SMC had begun an adoption(收养)program for the manatees.For a fee,sponsors(资助者)can name a manatee.Donations are used to help protect the manatees and their habitat.
45.The manatee is the kind of animal that___________.
A.1ikes living in the cold waters of Florida B.will die out if not protected in time
C.call dive in the deep sea for hours D.is the biggest living animal on earth
46.Why is it dangerous for manatees to be in a torpor state?
A.Because they come to the snlface to breathe,and that is when they are hunted.
B.Because they eat deadly algae,and this makes them too sick to avoid danger.
C.Because they live in groups and therefore they are easily hurt by passing boats.
D.Because they are sleepy when they surface,so they can,t avoid approaching boats.
47.The death of the manatees is largely due to__________.
A.human hunting B.human pollution

MONTREAL (Reuters) – Crossing the US-Canada border(边界)to go to church on a Sunday cost a US citizen $10,000 for breaking Washington’s strict new security(安全)rules.
The expensive trip to church was a surprise for Richard Albert, who lives right on the Canadian border. Like the other half-dozen people of Township 15, crossing the border is a daily occurrence for Albert. The nearby Quebec village of St. Pamphile is where they shop, eat and go to church.
There are many such situations in these areas along the largely unguarded 5,530-mile border between Canada and the US-which in some cases actually runs down the middle of streets or through buildings.
As a result, Albert says he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada, as usual. The US customs(海关)station in this are is closed on Sundays, so be just drove around the locked gate, as he had done every weekend since the gate appeared last May, following a tightening of border security. Two days later. Albert was told to go to the customs office, where an officer told him be had been caught on camera crossing the border illegally(非法).
Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country when Canadian customs stations are closed, but the US stopped a similar program last May. That forces the people to a 200-mile detour along hilly roads to get home through another border checkpoint.
Albert has requested that the customs office change their decisions on the fine, but he has not attended a Sunday church since. “I feel like I’m living in a prison,” he said.
60.We learn from the text that Richard Albert is .
A.an American living in Township 15
B.a Canadian living in a Quebec village
C.a Canadian working in a customs station
D.an American working in a Canadian church
61.Albert was fined because he .
A.failed to obey traffic rules B.broke the American security rules
C.worked in St. Pamphile without a pass D.damaged the gate of the customs office
62.The underlined word “detour” in paragraph 5 means .
A.a drive through the town B.a race across the fields
C.a roundabout way of travelling D.a journey in the mountain area
63.What would be the best title for the text?
A.A Cross-country Trip B.A Special Border Pass
C.An Unguarded Border D.An Expensive Church Visit

In the world today, all of the people need recreation (消遣). We cannot work all the time if we are going to keep healthy and enjoy life.
Everyone has his own way of relaxing. Perhaps the most popular form is to take part in sports. There are team sports, such as basketball and football; There are also individual (个人的) sports, such as swimming and running. Skating and mountain climbing are the most popular recreation for people who like to be outdoor.
Not everyone who enjoys sports likes to take part in them. Many people like watching them on TV or listening to them on the radio. So many people like some forms of indoor recreation, such as watching TV, singing and dancing.

Once when I was nine, I came down with a horrible case of tonsillitis (扁桃腺炎).I remember going to the doctor, feeling miserable and scared, but also knowing that this man would somehow fix me.As he declared his conclusion regarding my illness, he asked my mother “Is your daughter allergic (过敏的) to any medicine? ”My mom hesitated for a moment, while I was looking at her questioningly.Was I allergic to anything?What if I was?What would happen to me?My mother said no.
That evening after taking my pill, I began to shake uncontrollably.I complained of a terrible headache and continued shaking as my mother held me.She didn’t seem very concerned, yet I believed I was allergic to the pill.Before I fell asleep that night, I told my mom the medicine had made me sick and I wouldn’t take it anymore. The next morning, my mother had me drink a tall glass of ice tea that tasted funny.Later that afternoon, my mom asked me how I felt.I told her I was doing much better, and that was when she dropped the bomb on me.She told me she had mixed my ice tea that morning with my medicine.Guess what, no allergic reaction.I was never allergic to the pills, but my powerful subconscious (潜意识的) mind, accepted a mere suggestion by the doctor that I might be, and my body acted accordingly.
Most of us have no idea how powerful our minds are, and how incoming information continually affects our experience.When I took that pill, it had a negative(负面) effect on my mind. Researchers are finding more and more evidence that what we believe, or expect to happen medically, has a deep effect on what actually does happen.
In some medical tests, the patients never took any medicine, only sugar pills, but were told they had been given expensive medicine, and their conditions improved anyway.They simply believed they would get better.On the other side of the coin, people who believe they are going to die in an operation have a higher death rate than people who don’t.
What we expect often tends to get realized. The power of your mind to heal your body is absolutely fantastic.Take care in what information you choose to believe about your health and well-being.Think positively about your outcome in medical situations and allow your power of belief to help you heal.

On March 23, 2010, Google Inc took a major step in withdrawing(收回) its search-engine services from Beijing to Hong Kong. Google acknowledged that it failed to make progress in talks with the Chinese government for permission to let Google stop censoring(审查) its search results.
Since posting the announcement on its website, Google’s stock(股票) price has fallen from $595 to about $567, while Baidu, the leading search engine in China, has seen its stock price rise by 50%. A potential foreign beneficiary(受益者) is Bing, Microsoft’s new search engine. And while Bing may not exactly have got the keys to a very rich kingdom, its managing group understand their good fortune and have not been shy about sticking the knife into Google. Craig Mundie, a chief officer of Bing, told China Daily that “we feel good enough now,” adding, “but it’s a 20-year journey, and not just three years. And Microsoft is here to stay.”
Several other Chinese Internet companies are no doubt moving swiftly to take advantage of this situation. Both Sohu. com—a Yahoo-like website in China— and a hugely successful instant-messaging company called Tencent(腾讯) are already trying to hire Google China staff. Analysts believe that of the two, Tencent is in the better position. Nearly 70% of China’s 400 million Internet users use instant-messaging, and of those, 80% use Tencent’s system, known as QQ. That’s the major reason why Tencent’s potential market is bigger than Baidu’s, and an insider at the company acknowledges that the search business is full of opportunities.
All the competitors of Google do what the Chinese government requires: censor their search results. If Microsoft and the others intend to be in China “to stay,” as Craig Mundie put it, there is no chance that the censoring principle will change for them.
As to the Google’s exit, one of its investors made the comment recently, “There’re still a lot of us who believe that they’ve made the wise choice. But Google is apparently out and I guess we just get to accept.” However, some Chinese netizens regretted the loss of its professional services on google. cn, such as maps, videos, music and translations.

A. too many companies enter the market B. its stock price has fallen sharply
C. Chinese companies hire its workers D. it refuses to censor the search results
74.How many Chinese beneficiaries are mentioned in the passage?

A. Chinese netizens won’t have any professional service
B. only Chinese companies will provide search service
C. China’s attitude towards censoring won’t be changed
D. the Google managing group will regret its decision
76.A suggested title for this news would be ______.
A. When Google Withdraws From China B. Who Wins in China’s Search Business

Obesity(肥胖) in children and adolescents is rising at an alarming rate. Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.
Children are considered to be overweight if the BMI(Body Mass Index) is over 85% of the weight group in their age and sex categories. If it is 95% and over, they are considered to be obese. Adolescents are generally judged according to adult criteria(标准) for obesity, although there are other considerations in this population, for many factors will affect the result of these measurements.
Causes and Risk Factors for Obesity in Children
Lifestyle Factors. Without educational or parental guidance, children are extremely greatly exposed to the cultural pressures that are largely responsible for growth of the obesity. Neither the media nor the educational system has strong programs that encourage healthy way of life, including exercise and healthy foods. The following are some specific problems created by the culture:
﹡Too much television watching plays an important role in obesity in children. Not only is it a passive activity, but television also offers countless temptations(诱惑) with its advertisements for fast foods, sugar cereals, and unhealthy snacks. In one study obesity rate were lowest in children who watched television one hour or less a day and highest in those who watched four or more hours.
﹡Sugar, particularly from soda, other sweet drinks, and fruit juice, may be major contributors to childhood obesity. One study reported that drinking soda regularly increases a child’s risk for obesity by 60%.
﹡Less physical exercise and greater sitting activities play another significant role in obesity in children. A high level of physical activity – not just using up energy – is important for weight control in young people.
Family History. Parental obesity more than doubles the risk that a young child, whether thin or overweight, will become obese as an adult. In older children and teenagers, obesity in parents starts to affect less as a predictor(预言) for body weight than their own weight. The risk may be due to environmental or genetic factors, or both.
Ethnic and Socioeconomic Factors. As in adult populations, children from lower socioeconomic groups and minority populations are at higher risk for obesity. For example, among young Mexican Americans and African Americans, there has been an increase in overweight trend of about 13% to over 23%.
