The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise. Millions of individuals became (1) in a variety of aerobic activities, and (2) thousands of health spas (3) around the country to capitalize on this (4) interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed (5) to this aerobic fitness movement, even a national chain with spas in most major cities. However, their (6) was not on aerobics, (7) on weight-training programs de signed to develop muscular mass, (8) , and endurance in their primarily male (9) These fitness spas did not seem to benefit (10) from the aerobic fitness movement to bet ter health, since medical opinion suggested that weight-training programs (11) few, if (12) , health benefits. In recent years, however, weight training has again become in creasingly (13) for males and for females. Many (14) programs focus not only on devel oping muscular strength and endurance but on aerobic fitness as well. (15) , most physi cal-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily (16) such fitness components have been related to (17) in athletics. (18) , in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health (19) as well. The American College of Sports Medicine now (20) that weight training be part of a total fitness program for healthy Americans.

【单选题】The aim of "Noah’s Ark" project is to（） A. implant embryo into a host animal B. salute the Chinese efforts in saving pandas C. save endangered animals from extinction D. introduce cells from a dead fe...
A.
With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A＆M University researcher has been undertaking for the past five years in a project called "Noah’s Ark".
B.
Dr. Duane Kraemer, a professor in Texas A＆M’s College of Veterinary Medicine and a pioneer in embryo transfer work and related procedures, says he salutes the Chinese effort and "I wish them all the best success possible. It’s a worthwhile project, certainly not an easy one, and it’s very much like what we’re attempting here at Texas A＆M—to save animals from extinction. "
C.
Noah’s Ark is aimed at collecting eggs, embryos, semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future.
D.
It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
E.
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.
F.
The entire procedure could take from three to five years to complete.
G.
"The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. 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 Missyplicity Project at Texas A＆M, the first-ever attempt at cloning a dog.
H.
"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 applaud 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.

B.
The Chinese scientists use (8) but they also monitor strange (9) such as various ground noises, the fluctuation of well-water levels, and the strange behavior of animals.

The seismologists say that their predictions have been (12) precise that they were able to evacuate many of their people (13) an earthquake occurred, (14) saving thousands of lives. (15) , the Chinese experts also admit that there have been some false alarms.
C.
American scientists have (16) stories of unusual prequake animal behavior before, but they (17) them too seriously until their recent visit to China. "Maybe there’s (18) in it", said Jack Everndon, a California scientist. We need some kind of short-term warning. We need something.
D.
He didn’t mention the kind of research he may be considering, "Some of us are thinking it’s (19) enough to give it a serious look," he commented. "Two years ago we (20) that.
