Noah’s Ark was 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, said there would be enough of the basic building blocks to reintroduce the species in the future.
It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was 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 were then trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nucleus 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 believed. “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, ”added Kraemer, who was 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. ”
At present, the project has worked. The number of the pandas has increased to more than 1, 500.

答案
小题1:B
小题2:A
小题3:C
小题4:D
解析
本文讲述的是十年前中国竭力克隆濒临绝种的熊猫, 这和Texas A & M University的Noah’s Ark工程极为相似, 都是想拯救濒临灭绝的动物。
小题1:选B。推理判断题。从第二段内容可知, “诺亚方舟”工程的目标是把濒临灭绝的动物的蛋(卵)、胚胎、精液和DNA储存在液体氮中, 如果某一种动物濒临灭绝时, 将来可以重现这一动物。
小题2:选A。细节理解题。从第六段第一句“The nucleus transfer of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem”可以做出正确判断。
小题3:选C。主旨大意题。从文章内容来看, 无论是中国还是世界克隆熊猫还没有成功, 所以排除A、B项; D项内容明显与文章内容不符, 故排除。所以“探索克隆熊猫的可能性”应该是这篇文章的标题。
小题4:选D。推理判断题。此题B项的干扰性较强, 但由于它没有说明是Chinese scientists, 所以应排除。A、C项明显与原文不符。根据文章第三段第一句可知选D。

In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.
Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.
Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(证据)to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.
But so far, no one has found bones or any other definite proof that the giant creature exists.
As a result many people believe the evidence is just part of a big trick.
The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.
They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.
小题1: So far what we can be sure about is that .
| A．there exist savages(野人)in several places in the world |
| B．there are some traces of hair, footprints and body prints of the “bigfoot” |
| C．bigfoot is a direct descendent of ancient gigantopithecus |
| D．all the big foot discovered have the same look |
| A．1999 | B．the 1960’s |
| C．the 1950’s | D．the 1940’s |
| A．may fool the world into believing |
| B．have definite evidences to prove |
| C．refuse to believe |
| D．will soon offer proofs of |
| A．apes |
| B．bears |
| C．gigantopithecus |
| D．people dressed in animal skins |
First of all, a lot of professional photographers give respect to these animals and the environment they are in. Just remember that you should respect the animals and the environment in case these animals bite or hurt you.
Keep in mind that you are taking pictures of real, live, wild animals. A wild animal may bite to protect itself. You must be sensitive while taking their pictures and be gentle in all your movements. Do not feed the animals, or interact with animals that are sleeping or caring for their young.
If you are going to a place where it is privately(私人)owned, you’d better get the owner’s permission first before you start taking pictures.
Change the flash of your camera to natural light, so the animals will not be frightened or surprised when you start shooting. Animals do not react well when they are surprised.
Be very patient. Make sure you are aware of the changes in behavior of the animal and its moods. Be familiar with the animals’ natural habitat.
Now if those rules are clear, it is time for planning. Consider the weather; some animals do not go out when it is raining while some animals love the rain. Therefore, a little research on the weather will not hurt. You should consider taking pictures after sunrise and before sunset. Now if the animal is nocturnal(夜间活动的), then you should prepare to battle not only the wild but also the darkness.
An adventure in the wild will make you very excited. However, you should be well equipped, have experts to back you up, and also a permit for doing the photo shoot. If you do not have any of these, then maybe you should consider visiting the zoo instead.

Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
Lost in the Wild
Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
Turkestanian salamander
This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
Gastric brooding frog
Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
Rio Pescado stubfoot toad
Last sighting: 1995, in South America
Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
小题1: Which of the following animals hasn’t been seen for over a century?
| A．Rio Pescado stubfoot toad. |
| B．Gastric brooding frog. |
| C．Turkestanian salamander. |
| D．Scarlet frog. |
| A．the scarlet frog used to live in Africa |
| B．researchers have no way to save amphibians |
| C．the scientists will search 14 countries at most |
| D．Robin Moore has begun his search for amphibians |
| A．Because they want to rescue the missing amphibians. |
| B．Because they want to set up a scientific program. |
| C．Because they want to do a scientific research on the missing amphibians. |
| D．Because they want to publish a report about the missing amphibians on WR News. |
| A．It’s hopeful. | B．It’s interesting. |
| C．It’s tiring. | D．It’s dangerous. |
Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of student affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”
IIT-Mumbai, with about 5,000 students, is one of seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional(不正常的) lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.
Starting Monday, Internet access will be banned between 11 p.m. and 12.30 p.m. at IIT-Mumbai’s 13 boarding buildings to encourage students to sleep early and to try and force them out of their “shells”, Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby(摇篮曲) to go to sleep,” said Rajiv, an electronics student.
小题1: What measure has been taken in IIT- Mumbai?
| A．Students have unlimited free Internet access in their dormitories. |
| B．Students are forbidden to surf the Internet. |
| C．Internet access is unavailable in deep night. |
| D．Students must go to bed before 11 p.m. |
| A．sleep through their lessons |
| B．break away from the Internet |
| C．go to sleep along with music |
| D．stop surfing, make friends |
| A．the banning order causes some complaints among the students |
| B．all electronics students hate the banning order |
| C．more students prefer listening to music to surf- ing the Internet |
