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(物种). That’s a move similar to what a 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. 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.” 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 |
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 |
The best title for the passage may be _______.

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.Not enough sleep can cause obesity by ______.
| A．burning more of your energy |

| D．have your hunger increase and your weight decrease |

The very first capsule hotel to be opened in Shanghai has attracted many budget travelers with its prices, even though it is not fully operational yet.
The hotel consists of 68 "capsules", each 1.1-meters high, 1.1-meters wide and 2.2-meters long. The basic rate is 28 Yuan ($4.22) per person, plus an additional 4 Yuan an hour. The hotel also offers a package of 68 Yuan for 10 hours and 88 Yuan for 24 hours.
All of the capsules are imported from Japan where capsule hotels originated，and each is equipped with independent sockets, clocks, lights, TV and wireless Internet service. The hotel also has a public lavatory(洗手间)，shower room, smoking room and shared guest room.
"This is a huge bargain compared with other budget hotels in Shanghai," said Ta Zan, the owner of the hotel. Ta used to stay at capsule hotels in Tokyo during his undergraduate years and worked at a capsule hotel while he was doing his MBA in Japan in 2005, so he knows how they work and how to make guests feel comfortable.
He based the hotel on capsule hotels in Japan but he has made some special changes based on Chinese guests' habits. "In Japan capsule hotels are usually equipped with bathtubs, but in China people are more willing to take a shower, so we have the shower room," he said. He has also separated the capsules into three snoring (打鼾的) zones so that guests who often snore won't disturb others. Like most of capsule hotels in Japan, the one in Shanghai is for men only.
But the idea of staying in such a compact space is not appealing to everyone. "I feel the idea is like putting a person in a coffin (棺材), and the price is also not that appealing. A bed at a youth hostel in Shanghai costs about 60 Yuan per night," said Wang Lei, a student from Beijing. The first capsule hotels in the world appeared in .
| A．Shanghai | B．Japan | C．Beijing | D．America |
If you stay in the capsule hotel in Shanghai for 8 hours， you will have to payyuan.
| A．28 | B．60 | C．68 | D．88 |
What does the underlined word "compact" mean?
| A．Dear | B．Cheap. | C．Close. | D．Clean. |
The capsule hotel in Shanghai differs from those in Japan in that.
| A．it serves men as well as women |
| B．its capsule is much larger |
| C．it has a shower room |
| D．it has no snoring zones |
We can know from the passage that.
| A．everybody considers the capsule hotel a nice place to stay |
| B．all the capsules of the hotel were made in China |
| C．each capsule of the hotel has a private lavatory |
| D．no guest has ever stayed in the capsule hotel in Shanghai |
Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks ---- we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do. Ray Birdwhistell believes that physical appearance ____.
| A．has little to do with culture |
| B．has much to do with culture |
| C．is ever changing |
| D．is different from place to place |
According to the passage, the final mouth shape is formed ____.
| A．before birth |
| B．as soon as one’s teeth are newly set |
| C．sometime after new teeth are set |
| D．around 15 years old |
Ray Birdwhistell can tell what area of the United States a person is from by ____.
| A．how much he or she laughs |
| B．how he or she raises his or her eyebrows |
| C．what he or she likes best |
| D．the way he or she talks |
