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

With the Indian economy predicted to grow by 7．5 percent this year, experts say it could be time for Western CEOs to learn some lessons from Indian CEOs．The key differences between Indian and Western bosses are:
Social purpose
One of the most important things is that Indian leaders lead with a sense of social purpose．Every leader in India gave a specific social purpose as being the goal of their business．Those purposes ranged from improving healthcare to getting cell phones to people who didn't have access to communication tools．Having a social purpose motivates workers．
Invest in employees
Indian firms invest an enormous amount in their employees' training and development．IT firms typically offer 60 days of formal training for newly hired workers and they even spend months training experienced workers．A study said that Western firms have largely abandoned investing in employees, seeing it as a waste if they quit．But Indian bosses believe that investing in employees ensures the quality of those who stay at the company．
Take the long view
Indian bosses stress far less on shareholders than it is typical at Western business．As a result they're more able to take a long-term view．Western companies can't just ignore their shareholders, but their CEOs can do more to protect their -employees from short-term financial pressures, letting them get on with their jobs．
Work from their strengths
Western companies often think about strategy in terms of chasing customers or pursuing market opportunities, but Indian firms will more often start by identifying their strengths and customers’ needs, and then try to meet those needs．
Act as a role model
Being a personal role model for their employees is an amazing thing for a CEO．If Western bosses could think of themselves as role models, it would have a real impact on their workers．
Indian CEOs use their sense of social purpose to _________．
A．improve the workers' healthcare system
B．provide cell phones to people in need
C．motivate and encourage their employees
D．promote the development of communication systems
Western firms have largely abandoned investing in employees’ training and development because _______．
A．it takes too long to complete the formal training of newly hired workers
B．they often hire experienced workers who don't need much training
C．they are afraid of the losses brought about by the resignation of employees
D．they don't care about the quality of the employees in their firms
Which of the following is TRUE about Western bosses?
A．They stress on workers more than shareholders．
B．They always act as role models for employees．
C．They are good at identifying their own strengths．
D．They pay closer attention to market opportunities．

“I’ve decided to apply for the test to enter a medical college to become a doctor, changing from my original plan to prepare for a lawyer qualification exam in order to get a more stable job in the future,” said a 24-year-old college graduate, Lee, who majored in business administration during his undergraduate schooling.
The new medical and dental school system is getting popularity, attracting an increasing number of students every year since its appearance in 2004, as it is open to all college graduates regardless of their previous majors.
The Education Development introduced the new medical and dental education system, in which college students with bachelor’s degrees are allowed to study medicine or dentistry by taking the Medical Education Test (MET) and Dental Education Test (DET).
Ten medical schools and six dental colleges that have used the new system have received 4,377 applications (申请) for the entrance exams.
Applicants are getting younger compared with those in their 20s representing 76.9 percent of the total. The tests might be easier for students with biology and chemistry majors, but graduates from other majors are also applying for the tests.
Under the existing medical and dental education system, students should take a two-year premedical course followed by a four-year medical course.
Students graduating under the new medical or dental education system are given master’s degrees, while those graduates who studied under the previous system have bachelor’s degrees.
1.Why do more and more Korean students apply for medical schools?
A．Because doctors are highly respected in Korea.
B．Because they want to get a more stable job.
C．Because medicine is easier to learn than other subjects.
D．Because the medical education system is reasonable.
2.Students in the old system may spend _______ years at college to get bachelor’s degrees.
A．two B．four C．six D．seven
3.We can learn from the passage that _______.
A．it takes a longer time to get the master’s degree in the old system
B．students may find it a lot easier to get a bachelor’s degree in medicine
C．graduates from other majors like history are not allowed to apply for those schools
D．the new system are not so popular as expected because of its high unemployment
4.What would be the best title for the passage?
A．New Medical and Dental School System Is Carried Out in Korea
B．Korean College Students Have a New Job Choice
C．Korean College Students Rush to Medical and Dental Schools
D．Doctors Are Becoming Popular in Korea
