KATHMANDU, Nepal (CNN) - Nepal has given its security personnel permission to shoot pro-Tibet demonstrators during China's Olympic flame climb to Mount Everest's summit early next month.

"About 25 soldiers and policemen have established camps on the mountain and they have been ordered to use force if necessary to stop any anti-Chinese activities," Mod Raj Dotel, spokesman for the home ministry, said Sunday. "This could mean shooting if necessary."

Security personnel will also check mountain climbers for non-essential expedition materials, Dotel added.

"If anyone is found with anti-Chinese material their permit will be canceled and returned from the mountain," he said.

Chinese climbers plan to take the Olympic flame to the top of the world's highest peak, at 8,848 meters (29,028 feet) as part of the global relay leading up to the August 8 opening of the Summer Olympics in Beijing.

Spring is the most popular season for climbing Mount Everest, which straddles(跨越) the border between Nepal and Tibet, an autonomous region of China.

The Nepali government has given permits to dozens of climbers from 30 expeditions this season.

But between May 1 and May 10, climbers are barred from going above 6,400 meters until the torch run is completed. China plans to take the Olympic flame to the summit sometime then.

Bad weather conditions allow only about two opportunities in May for a push to the summit.

The Chinese have not allowed any expedition to climb the mountain from the north side, according the Kathmandu representative of the Tibet China Mountaineering Association.

Almost every day in the past month, Nepalese police have arrested pro-Tibet protesters from in front of the Chinese Embassy and the United Nations offices. The demonstrators are released later in the evening.  

Supporters of Tibet punish the government's attitude toward the autonomous region, and many believe China should not have been awarded the honor of hosting the Olympic Games.

Earlier torch relay stops in London, England; Paris, France; and San Francisco, California attracted tens of thousands of demonstrators. They led to attacks on the torch and relay participants, and prompted police to make dozens of arrests.

Subsequent stops in Argentina, Tanzania and Oman were trouble-free.

In Pakistan, authorities closed the relay to the public. And India shortened the relay and kept thousands of anti-Chinese protesters at bay by sealing off roads and shuttering buildings along the route.

The relay went smoothly in Bangkok, Thailand, on Saturday, amid heavy security and scattered protests along the route.

The flame arrived in Malaysia on Sunday. About 1,000 police officers will be on hand to watch for protesters during a relay in the capital city Kuala Lampur Monday.

A new study finds that the animal known as man’s best friend can also be a good friend to the heart. Researchers in California say they have found that even just a short visit with a dog helped ease the worries of heart patients.               

The study divided the patients into three groups. In Group A, a dog and a person visited each patient for twelve minutes. Patients in Group B received just a human visitor for twelve minutes. And members of Group C received no visitor, human or canine(犬的).

The dogs would lie on the hospital bed so the heart patients could touch them. The researchers say some patients immediately smiled and talked to the dog and the human visitor. Dogs, in her words, “make people happier, calmer and feel more loved.”

The researchers examined the patients before, during and after the visits. They measured stress levels based on blood flow and heart activity. They say they found a twenty-four percent decrease in the group visited by both a dog and a person. They reported a ten percent decrease in the group visited by a person only. There was no change in the patients without any visit. These patients, however, did have an increase in their production of the hormone epinephrine (epinephrine腎上腺素). The body produces epinephrine during times of stress.

The increase was an average of seven percent. But the study found that patients who spent time with a dog had a seventeen percent drop in their levels of epinephrine. Patients visited by a human but not a dog also had a decrease, but only two percent.

The author believes that _______.  

   A. the dog can take the place of most medicines

   B. the dog is the most popular pet for man

   C. the findings of the research cannot be trusted

   D. visits by a human work better than visits by a dog

Which of the following best shows the stress level changes in the groups of patients? BACC

  

From the research findings we may conclude that _______.

A. the less the body produces epinephrine, the better

B. the longer a visit lasts, the happier the patient should be

C. the patients enjoyed the dogs’ company more than the human visitors’

D. it’s impossible for heart patients to recover without dogs’ visits

Which of the following is the best title for the passage?

  A. Worried Heart Patients               B. Epinephrine and Stress

  C. Good Friend to the Heart             D. Three Groups of Patients

A classic series of experiments to determine the effects of overpopulation on communities of rats was conducted by a psychologist，John Calhoun．In each experiment，an equal number of male and female adult rats were placed in an enclosure（場(chǎng)地）．The rat populations were allowed to increase．Calhoun knew from experience approximately how many rats could live in the enclosures without experiencing stress due to overcrowding．He allowed the population to increase to approximately twice this number Then he fixed the population by removing the children that were not dependent on their mothers．At the end of the experiments，Calhoun was able to conclude that overcrowding causes a breakdown in the normal social relationships among rats，a kind of social disease．The rats in the experiments did not follow the same patterns of behavior as rats would in a community without overcrowding．

       The females in the rat population were the most seriously affected by the high population density（密度）．For example，mothers sometimes deserted their children，and，without their mothers’care，the children died．The experiments showed that in overpopulated communities，mother rats do not behave normally．Their behavior may be considered diseased and pathological（病理學(xué)的）．

       The leading males in the rat population were the least affected by over population．Each of these strong males claimed an area of the enclosure as his own．Therefore，these individuals did not  experience the overcrowding in the same way as the other rats did．．However leading males did behave pathologically at times．Their antisocial（反社會(huì)）behavior consisted of attacks on weaker male，female，and immature rats．This unusual behavior showed that even though the leading males had enough living space，they too were affected by the general overcrowding．

       Non-leading males in the experimental rat communities also exhibited unusual social behavior．Some withdrew（縮回） completely ,avoiding contact with other rats．Other non-leading males were too active，chasing other rats and fighting each other．

       The behavior of the rat population has similarity in human behavior．People in densely（密） populated areas exhibit unusual behavior similar to that of the rats in Calhoun’s experiments．In large urban areas，such as New York City，London，and Cairo，there are deserted children．There are cruel，powerful individuals，both men and women．There are also people who withdraw and people who become too active．Is the major cause of these disorders（混亂）overpopulation?

       Calhoun’s experiments suggest that it might be．In any case，social scientists and city planners have been influenced by the results of this series of experiments．

Which of the following inferences（推斷）can NOT be made from the first paragraph?

       A．Overpopulation causes pathological behavior in rat populations．

       B．Calhoun had experimented with rats before．

       C．Calhoun’s experiment is still considered important today

       D．Stress does not occur in rat communities unless there is overcrowding．

The author implies that the behavior of the leading male rats is sometimes similar to that of

       A．people who would like to keep to themselves 

       B．people who abandon their children

       C．too active people

       D．cruel，powerful people

The main point of this passage is that _______________．

       A．a(chǎn)lthough rats are affected by overcrowding，people are not

       B．overcrowding may be an important cause of social pathology

       C．the social behavior of rats is seriously affected by overcrowding

       D．Calhoun's experiments have influenced many people

A new study shows one of the largest glaciers① in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.

The rates② of change that we’re noticing are much higher than expected. If these rates continue, it is not unlikely that Greenland could shrink③ by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.

Greenland is the world’s largest island, covering an area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.

Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past four years, its trip to the sea has sped up from about 70 feet per day to nearly 110.

The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit in the last decade. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen anytime soon.
