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.”

Being a senior high school student, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford’s graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.
It started when I became a junior, when college came into view. It’s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He also felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn’t mean that students shouldn’t attend college, but rather that they shouldn’t worry so much. You'll get where you need to go, even if your path is a bit more winding than you'd like.
Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don’t panic. One particular part of his speech stayed with me. Steve Jobs quoted the saying “Stay hungry, stay foolish” and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you've learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs’ level of success is possible to achieve, and I aim to prove that. With the will power to go into the world living every day like it’s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I’ll be proud of what I have done and hope to have all the wisdom a person could wish for.The author felt worried when_______.

An Israeli law banning too skinny models went into effect with the start of 2013. The law, approved last March in Israel, requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months before a fashion show. That means a woman who is 5'8''tall can weigh no less than 119 pounds.
“This law is another step in the war against eating disorders,” said physician Adatto. “Underweight models,” he explained, “can no longer serve as role models for innocent young people who copy their false image of being skinny.”
But some critics in this country say it is misguided, focusing on weight instead of health. They also say the Israeli ban is bound to fail because of the strong power of the fashion industry. “I think it’s an approach that isn’t going to work.” Said eating disorder expert Susan Ice, who worked with an organization which creates a healthy working environment for models.
But Adatto told the reporter that he began to concern the issue after meeting an ambitious model who looked like she needed to be hospitalized. He said. “I realized that only legislation can change the situation. There was no time to waste, so many girls were dieting to death.”
However, the efforts to regulate models’ weight in Spain and Italy have not resulted in significant changes in part because of difficulties in determining reliable methods of measuring weight and health.
Still, folks including Ice say there’s no denying that images from Hollywood and the fashion industry can be difficult for young women to deal with. “Certainly I don't believe the modeling industry has caused the rise in eating disorders, but it makes it harder,” she says. “It’s a difficult recovery environment, worshiping thinness as the beauty ideal.”What does BMI in the first paragraph refer to?
A.A measure of body health based on height and weight. |
B.A worldwide prize for the healthiest model. |
C.A new show held by those skinny models. |
D.A kind of medicine to cure eating disorders. |
One benefit the new Israeli law may bring is ________.
A.to change the working conditions of models |
B.to lower the chance of skinny models’ death |
C.to prevent models from suffering from eating disorders |
D.to provide guidance for women worshiping thinness |
In the opinion of the critics, the law won’t succeed because .
A.it misleads young women to form a bad eating habit |
B.the fashion industry is much too influential |
C.it doesn’t provide a proper approach that can work well |
D.it doesn’t create a healthy working environment for models |
What caused Adatto to think that a law was needed to change the situation?
A.Establishing his fashion model agent. |
B.Meeting an ambitious but too skinny model. |
C.Being interviewed by a reporter. |
D.Seeing a model die from eating disorders. |
According to the passage, the new Israeli law banning skinny models is .
A.practical | B.acceptable |
C.reasonable | D.Controversial |
A 12-year old boy who donated bone marrow (骨髓) to his dying sister and has raised more than£10,000 for charity has been named the UK’s Family Hero of the Year.
Adam Kerr, 12, from Armagh, Northern Ireland, also helps his mother care for his younger brother Brian, 9, who suffers from the genetic disease Fanconi’s anaemia (贫血症). But it is not the first hardship that has affected young Adam. When he was just six, he donated his own bone marrow to his younger sister Helen who suffered from a rare blood disorder. Sadly she developed complications and died a few months after the operation in 2005.
Adam found it very difficult to be happy after Helen’s death. So he decided to start raising money in memory of Helen to help local poor children and families with bereavement (丧亲之痛). Overall he has raised £10,000 and he has no intentions of giving up.
He organised a Fun Day to provide the money for a brother and sister from Northern Ireland to visit their sick brother having a bone marrow transplant in a London hospital.
He received his award and a cheque for£2,000 at an “Oscar’s style” ceremony in London. Ms Phillips said: “Adam is an incredible young man. In his relatively short life he has faced real sadness and bad luck and yet he works tirelessly to make life better for others.”
The Awards were sponsored by the charity 4Children and Take a Break Magazine. Anne Longfield OBE, Chief Executive of 4Children said:“It’s an honour to recognise Adam’s devotion and self-sacrifice, and his bravery shows there is always reason for hope and optimism. There is so much unrecognized goodwill out there of people who do so much for others, and the inspiring winners of the Family Heroes Awards remind us how important it is for us all to do our best to make a difference in the lives of others.”From the passage we can see Adam’s younger brother .

More than one-third of adults in the United States are obese(肥胖). In fact, over obesity has reached such proportions that one big-city mayor has gone about banning large-sized, sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools.
Even many adults who do not fit the clinic definition of obesity are still overweight, and a large percentage are looking for the best ways to lose weight.
Reducing pounds largely comes down to the two-sided factors of diet and exercise. Not carrying out the first one enough, and not getting enough of the second one, ends up giving the individual a recipe for being overweight.
Advising someone to eat less and exercise more might be the easiest advice possible, but it’s also, partially, an oversimplification. Dieting has more to do with the types of food you eat than how much you eat. Reduce the amount of red meat in your diet. If you don’t want to eliminate red meat altogether, choose cuts of meat with less fat content. Limit your intake of salt and starches. If you’ve got to have potato chips alongside your sandwich at lunch, choose the baked potato chips that contain less fat than the deep-fried chips. You might find you’re really not sacrificing that much in terms of taste.
A diet rich in fruits, vegetables, egg whites, fish and nonfat dairy products will certainly aid in the mission of losing weight. Drink more water and less sugary drinks. If you have to have a soda, a diet soda is a better option, but seltzer is an even better choice than that.
It’s important—if not always easy—to make sure you get at least some physical activity each and every day. If your feet won’t allow for a regular jogging regimen, then make sure you take lots of walks. Next time you need to mail a letter, walk to the mailbox instead of driving. Try to work in a daily walk in your neighborhood. You shouldwhen you want to lose weight
A.try not to fit the clinic definition of obesity |
B.diet as well as exercise enough |
C.get little exercise every day |
D.focus your attention on diet only |
The First Lady has started a movement to.
A.raise people’s awareness of healthy diet |
B.control the public school dietary supplying |
C.ban the sugary soft drinks |
D.realise the importance of dieting |
What can we learn from the fourth paragraph?
A.We must keep far away from fat and ignore our taste. |
B.The simplest and best way to lose weight is to eat and exercise more. |
C.We should remove the red meat in our diet completely to reduce weight. |
D.When it comes to diet, no one needs to starve themselves in order to lose weight. |
The last paragraph is mainly about.
A.walk | B.diet |
C.exercise | D.jog |
It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little leery of the security levels.
Internet giants such as Microsoft knew consumer confidence was the key to getting virtual(虚拟)shopping off the ground, and they work hard to make people feel safe to shop online.
Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund(返还) your money and then set their claws on the company that wronged you. Now that’s buying power!
There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won’t get them what they want.
When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn’t be any easier. And thanks to courier companies(速递公司)getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door.
No wonder so many companies are shaking their heads at traditional advertising and instead looking to the “virtual” world to attract online shoppers. The underlined word “leery” means.
A.satisfied | B.distrustful |
C.hopeful | D.sad |
leads to consumers’ trust in online shopping.
A.Shopping law | B.Shopping convenience |
C.Internet access | D.Shopping security |
Which group of words would the writer use to describe current Internet shopping?
A.Adventurous, enjoyable, fast, unreal. |
B.Unsafe, cheap, slow, convenient. |
C.Reliable, popular, convenient, slow. |
D.Safe, convenient, fast, comfortable. |
The following are thought to have made contributions to the popularity of online shoppingEXCEPT_________.
A.internet companies | B.courier companies |
C.advertising companies | D.credit card companies |
