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（氮）. If certain species should become extinct , Dr. Duane Kraemar, a professor in Texas A&M University 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 |

As the richest country in the world, you'd expect that Qatar would also be the happiest. And you'd also expect Japanese people to be extremely positive, seeing as though they have the highest life expectancy. But clearly wealth and good health do not guarantee happiness after both countries failed to make the top ten most positive countries.
The poll (民意测验 ) of nearly 150,000 people around the world found that seven of the world's 10 countries with the most upbeat attitudes are in Latin America. Gallup asked about 1,000 people in each of 148 countries if they were wellrested, had been treated with respect, smiled or laughed a lot, learned or did something interesting and felt feelings of enjoyment the previous day.
In Panama and Paraguay, 85 percent of those polled said yes to all five, putting those countries at the top of the list. They were followed closely by El Salvador, Venezuela, Trinidad and Tobago, Thailand, Guatemala, the Philippines, Ecuador and Costa Rica.
The people least likely to report positive emotions lived in Singapore, the wealthy and orderly citystate that ranks among the most developed in the world. Other wealthy countries also sat surprisingly low on the list. Germany and France tied with the poor African state of Somaliland for 47th place.
Many of the seven countries which were most positive do poorly in traditional measures of wellbeing, like Guatemala, a country torn by decades of civil war followed by waves of gangdriven criminality that give it one of the highest killing rates in the world. Guatemala sits just above Iraq on the United Nations' Human Development Index, a composite of life expectancy, education and per capital income. But it ranks seventh in positive emotions.
In Guatemala, it's a culture of friendly people who are always smiling, said Luz Castillo, a 30yearold surfing instructor. Despite all the problems that we're facing, we're surrounded by natural beauty that lets us get away from it all.
The poll shows that prosperous nations can also be deeply unhappy ones. And povertystricken ones are often positive, or at least a close approximation (类似事物) of it.________ may feel the most unhappy according to the poll.
| A．People from Qatar | B．People from Thailand |
| C．People from Japan | D．People from Singapore |
The underlined word “Gallup” in Paragraph 2 refers to ________.
| A．a country | B．a polling organization |
| C．a person | D．a magazine |
Which of the following is NOT included in the United Nations' Human Development Index?
| A．Life expectancy. | B．Education. |
| C．Natural beauty. | D．Per capital income. |
What's the best title of the text?
| A．Happiness does not depend on wealth |
| B．How to live happily? |
| C．Health leads to happiness |
| D．What are the standards to be happy men? |
Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes (密码) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake (假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip, you would need an operation to remove it.The Verichip is ________.
| A．the identity number | B．the security code |
| C．a tiny microchip | D．a radio reader |
Which is true of the Verichip?
| A．Your information on it will always be safe. |
| B．Medical records have already been included. |
| C．You can easily reach for your wallet using it. |
| D．An operation has to be performed to remove it. |
Life is like the four seasons. Now I am very old, but when I was young, it was the spring of my life. I was born. I played a lot, and then I started school. I learned many new things. Like a flower, I grew bigger everyday. There were happy days and tragic days; some days the sun shone, and some days it didn’t.
In my twenties, I had a good job. I was strong and happy. Then I married and had a child. In those days, I didn’t have much time to think. Every day, I was busy and worked very hard. And so, I started to get some white hairs. The summer of my life passed quickly.
Then the days got shorter. Leaves fell from the trees. My child was a university student, and then an engineer. My home was much quieter. I started walking more slowly. One day I stopped working, I had more time. I understood this was my autumn, a beautiful time when the trees change colour and give us delicious fruits.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel” (燃料). Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise forms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.According to the passage,_________.
| A．we should always keep fit |
| B．if we were healthy, we could spend our days in doing things with less sleep |
| C．one can eat a lot to stay in good shape |

In order to keep good health, ___________ .
| A．we should eat a lot of sweets |
| B．one needs a large amount of fat |
| C．people should eat according to the foods nutrition |
| D．we must try to sleep now and then |
