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.

61．When will China's Olympic flame probably reach Mount Everest's summit?

A．April 28 B．May 12 C．June 10 D．May 7

62．The underlined word “barred” means_____________.

A．permitted B．stopped C．encouraged D．introduced

63．How many times Climbers can reach the top of the mountain at most in May?

A．once B．twice

C．three times D．as many times as they can

64．Where did the torch relay meet no trouble?

A．India B．Nepal C．Tanzania D．France

65．What is the attitude of the Nepali government towards towards China's Olympic flame climb to Mount Everest's summit?

A．negative B．positive C．ambiguous D．Indifferent

The Book of Life

So far, scientists have named about 1.8 million living species（物种）, and that’s just a small number of what probably exists on Earth. With so many plants, animals, and other living things coveting the planet, it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.

A soon-to-be-started Web site might help. An international team of researchers has announced the creation of Web-based Encyclopedia （百科全书）of Life（EoL）. The project aims to list every species on Earth in a single, easy-to-use reference guide.

To get the encyclopedia started, the creators will use information from scientific databases （数据库） that already exist. And eventually, in special sections of the site, non-scientists with specialized knowledge will come to help. Bird-watchers, for example, will be able to input what birds they’ve seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it.

As the EoL develops, you might find it useful for school projects. The site will feature （以……为特色）special pages for kids who are studying ecosystems in their neighborhoods. Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests, age, and knowledge.

It now takes years for scientists to collect all the data they need to describe and analyze species. The creators of the Encyclopedia of Life hope that their new tool will speed up that Process.

60. The Web-based EoL aims to__________ .

A. find out what covers the earth B. list all living things on Earth

C. work out the number of birds D. save the existing plants

61. One characteristic of the EoL is that__________ .

A. it is run by school students B. it focuses on different types of grass

C. it provides different levels of information D. it allows non-scientists to review its data

62. In the last paragraph, "that process" means__________ .

A. analyzing species B. creating a new tool C. collecting data D. describing species

“It’s our tradition to help each other”, added Tenpa, a medical official in neighbouring Madoi County, who said Yushu has always been quick to help other areas in times of trouble. “We have suffered many dangers and each time people in Yushu have sent food and clothes. We are always thankful to them and hopefully we proved it by being the first rescue team to arrive in Yushu after the earthquake.”

The Madoi medical team arrived just hours after the violent 7.1-magnitude earthquake hit Yushu. In two weeks, they have treated at least 1,800 people, while the county has donated 400,000 yuan.

The biggest fear in the earthquake area is the outbreak of diseases. Tenpa said, “Keeping things clean in the shelter is very hard. Even hand washing is almost impossible because of lack of water. Our team is spraying disinfectant (喷洒消毒剂) and we hope that will work.”

After driving for 13 hours with his medical team, Tian Jiancan said he immediately found a 40-year-old who was seriously injured after being trapped in a toppled house. Tian had to operate on the man in his emergency medical van. “If we had been one hour later, he would probably be dead. It’s good to see him out of danger now.” Tian’s medical team has treated over 3,200 people, including a 15-day-old baby and a 105-year-old man. They also helped to put up tents against winds, where patients are protected well.

One local man said although most doctors cannot speak Tibetan, they have shown their care and love through their actions.

60. Which of the following is TRUE according to the passage?

A. This is the first time that Tibetans have faced great dangers.

B. People in Yushu have always been ready to help each other.

C. Madoi was also hit by the 7.1-magnitude earthquake.

D. Tian’s team is the second rescue team to arrive Yushu.

61. What is the closest meaning to the underlined words in paragraph 7?

A. a house on the top floor B. a house which had no roofs

C. a house which fell down D. a house which was poorly built

62. How many people have been rescued by the medical teams according to the passage?

A. About 1,800. B. 3,200. C. At least 5,000. D. 4000,000.

63. What is the passage mainly about?

A. People in Yushu are encouraged by the medical team workers.

B. The doctors went along quite well in spite of the language trouble.

C. The Madoi medical team was the first to arrive at the earthquake-hit area.

D. The medical workers made great efforts to help the people suffering from the earthquake.

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species. That’s a move similar to what Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen(氮). If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

60. The aim of “Noah’s Ark” project is to _______.

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

61. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.

A. available panda eggs B. host animals

C. qualified researchers D. enough money

62. The best title for the passage may be _______.

A. China’s Success in Pandas Cloning

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China —the Native Place of Pandas Forever

63. From the passage we know that _______.

A. Kraemer and his team have succeeded in cloning a dog

B. scientists try to implant a panda’s egg into a rabbit

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand of species will probably die out in a century
