With only about 1, 000 pandas left in the world, China is desperately trying to clone 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.”

Because of the financial crisis in the US and UK, college students are beginning to struggle to find ways to pay their tuition fees and accommodations.
Recently, two major US student loan lenders — Citibank and JPMorgan Chase — announced they were leaving the student loan industry altogether. Because banks currently have a lack of credit, they are reluctant to offer students low-interest loans that need a several-year wait for any return of interest.
In the US, many undergraduates top up their financial needs with a private loan, although the majority can get government-funded loans. In the 2005-2006 academic year, $17 billion in private student loans was used to finance higher education. The shortfall in private funding has yet to be covered and will hit many US students hard.
Across the Atlantic, UK students have been less troubled by the crisis. Most undergraduates in the UK cover their university expenses with government-funded loans and grants (助学金). Their biggest concern is a sudden steep increase in student rent.
Most young professionals now rent houses, since 80 percent of UK mortgage schemes (住房抵押贷款计划) have disappeared — a direct result of the credit crisis. This has boosted the house rent market.
In large cities, UK students are paying almost 6.5 percent more in rent than the previous year. Figures from the UK organization Accommodation for Student show students in big cities such as London paying an average weekly rent of ￡103. Yet, despite students’ suffering, the number of this year’s university applications is expected to grow. During economic slumps (经济萧条时期), people regard further education as a way to survive tough job markets.According to the passage, banks are unwilling to offer students loans because ________.
| A．the students are poor and sometimes they can’t pay off the debt |
| B．banks prefer lending the money to the young professionals |
| C．banks don’t have enough money left at the present time |
| D．they think college students are not studying hard |
The underlined phrase “top up” in Paragraph 3 probably means ________.
| A．put up | B．make up | C．fill up | D．pick up |
Which of the following is NOT true according to the passage?
| A．UK college students have to pay more if they want to rent houses. |
| B．More UK students want to further their study in college. |
| C．It is not so easy for US students to loan money now. |
| D．College students’ tuition fees have risen greatly. |
It can be inferred that ________.
| A．there are no private student loan lenders in the UK |
| B．loans for US college students will be increased next year |
| C．private funding falls a little because of higher-interest loans in the US |
| D．private loans play a very important role in financing US students’ education |
It’s a goal for millions and millions of families every year——keep the Christmas spending within a certain amount, but can still afford the gifts that your loved ones will enjoy. Never has this concern been greater in recent years than right now. Even so, there are several things that you can do to help.
Hit the sales.
No one wants to get up at four o’clock in the morning and fight to get the best deal on Black Friday, and it’s surely very tough to pick up the courage and get out there in the cold for a good deal, but sometimes——it can be well worth. Many retailers(零售商) offer specials all through the day——and some even offer online Black Friday specials, so you may still be able to get a great deal on Black Friday.
Pay close attention to advertisements.
Once the Christmas shopping season is coming, retailers hungry for business will do just about whatever to get you in the store. Pay very close attention to weekly advertisements of sales among the major retailers and you may be lucky enough to find different prices for the same thing in different shops.
Shop online.
Some of us don’t like running from store to store in order to get the best price on the perfect gift, and some of us don’t like to go out in the cold at all——thankfully for us, we can do online shopping.
The world of online shopping lets people visit all the major retailers as well as some specialty stores that could only be found on the Internet.

Some time ago, I discovered that one of my chairs had a broken leg. I didn’t think there would be any difficulty in getting it mended, as there are a lot of antique (古董)shops near my home. So I left my home one morning carrying the chair with me. I went into the first shop expecting a friendly reception (接待). I was quite wrong. The man wouldn’t even look at my chair.
The second shop, though slightly more polite, was just the same, and the third and the fourth. So I decided that my approach must be wrong.
I entered the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, "Would you like to buy a chair?" He looked at it over carefully and said, "Yes, not a bad chair. How much do you want for it?" "Twenty pounds." I said. "OK," he said, "I will give you twenty pounds." "It’s got a slightly broken leg," I said. "Yes, I saw that, it is nothing. "the shopkeeper answered.
Everything was going according to my plan and I was getting excited. "What will you do with it?" I asked. "It will be easy to sell once the repair is done." "I will buy it." I said. "What do you mean? You just sold it to me." "Yes, I know, but I have just changed my mind, I am sorry. I will give you twenty - seven pounds for it." "You must be crazy." he said. Suddenly the penny dropped. "I know what you want. You want me to repair your chair." " You are right," I said, "What would you have done if I had walked in and asked you to mend the chair?" "I would not have agreed to do that. We don’t do repairs, not enough money in it, and too much trouble. But! will mend this for you. Will you pay it for five? ". He was a very nice person and was greatly amused (感到有趣)by the whole thing. We can learn from the passage that in the first shop the writer________.

It was getting dark and snow was coming down. Joe was driving home. He’d been unemployed since the factory closed. Most of his friends had left, but he stayed on. After all, he was born here.
Suddenly he saw a lady standing on the side of the road and pulled up. She was worried. No one had stopped to help her. Was he going to hurt her? He looked poor and hungry. Joe knew how she felt and said, “My name is Joe and I’m here to help you.” All she had was a flat tire, but for an old lady, that was bad enough. Joe changed the tire, but he got dirty and his hands were hurt. She wanted to pay Joe and said any amount would have been all right. Joe never thought twice about the money and there were plenty who had given him a hand in the past. He had lived his whole life that way. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance that they needed.
Later the lady went in a dingy-looking restaurant to grab a bite to eat. The cash register was like the telephone of an out-of-work actor----it didn’t ring much. The waitress, who was nearly eight months pregnant, brought a clean towel to her with a sweet smile. The old lady remembered Joe. After the waitress brought the change from a 100-dollar bill, she found the lady gone and something written on a piece of paper, “Someone once helped me out----the way I’m helping you. If you really want to pay me back, don’t let the chain of love end with you.”

“Few things help an individual more than to place responsibility upon him，and let him know that you trust him.” These words are from the black American educator，Booker Washington. He was saying that，“If you want people to grow up，you have to stop treating them like children.”
In America，families are close but children are encouraged to be independent，to make their own decisions，even at a very early age. It’s not unusual for a child of seven to be given an allowance(津贴)every week. The child is encouraged to save some of the money but he or she can spend it on whatever they choose，for example，buying clothes，school supplies or CDs. Some teenagers even have their own credit cards! That’s a big responsibility since even adults are tempted to overspend when they have credit cards.
From an early age，American children are asked for their opinions and they are included in family decision making. At the dinner table，teenagers will be listened to on any topic，from politics to buying a new family car or where the family will go on vacation. In this way, teenagers are getting practice in becoming individuals：they are learning how to stand on their own two feet.
Many Chinese young people are becoming almost as interested as American teens in searching for independence. They want to express those qualities that make them unique human beings. You can see this in the way they dress, the music they listen to and the friends they choose. “Super Girl” Li Yuchun caught the imagination of Chinese teenagers on the “Super Girl” television contest. She was not the traditional “nice，young Chinese girl”. With her short，spiky hair and boy-like clothes, she was telling everyone that she was different. She had the courage to be her own person and to stand on her own two feet...and she won!
There is an old saying，“Everyone should carefully observe which way his heart draws him and then choose that way with all his strength.” If you do this, step by step, over a period of time, you may find that you have become the person you always wanted to be.The passage is intended to encourage the youth to________.
| A．save money for useful things | B．become independent |
| C．express their great ambitions | D．make important decisions |
