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(氮). If certain species should become extinct, Dr.Duane Kraemar, a professor in Texas A&M University 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.”
1.The aim of “Noah’s Ark” project is to________.
A. make efforts to clone the endangered pandas
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another
2.The underlined word groundbreaking can be interpreted as __________.
A. especially new B. pioneering
C. damaging D. trouble- making
3.The best title for the passage may be ______.
A. China’s Success in Panda Cloning
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China---the Native Place of Pandas Forever
4.From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand species will probably die out in a century

Everyone is at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction (网上拍卖).
Buying for beginners: Sign up on www. ebay. co. uk. Most items(e.g. tables, computers, and books)ready for auction will come with a picture and a short description; others may be marked with “ Buy It Now ” and have a fixed price. You can buy these right away.
If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids(出价)for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish you get an email telling you whether you have won the item.
How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card (信用卡).
Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
The big things in life: It’s easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men. Check the ways of delivery before you bid.
1.What is the passage mainly about?
A.How to make payment online. |
B.Ways of using delivery online. |
C.Advantages of an online-auction system. |
D.How to use an online-auction system. |
2.After bidding for an item, a buyer __________.
A.will get what he wants in ten days |
B.should make payment immediately |
C.has chances to make higher bids |
D.may check its picture and description |
3.The easiest way of making payment mentioned in the passage is __________.
A.through an online payment system |
B.through a local banking system |
C.by sending the money to the seller |
D.by paying the deliveryman directly |

高二英语单项填空中等难度题查看答案及解析
China is showing the world its great resolve in the global climate campaign with concrete and self-motivated efforts as well as serious commitment.
At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China's plan made in June to cut its carbon emissions( 排放)per unit of GDP by 60-65 percent from 2005 levels by 2030, and increase non-fossil fuel sources in primary energy consumption to about 20 percent.
With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.
Actually, climate change efforts are already included in China's medium-and long-term program of economic and social development, and ecological efforts are the clear characteristics in China's 13th Five-Year Plan(2016-2020).
Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.
However, China's development rights need to be respected. It is unfair to overstress China's status as one of the world's largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.
It is worthy of notice that China's emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made it one of the biggest producers of the gases.
To show its great resolve, Beijing in September also announced the establishment of an independent South-South cooperation fund of 20 billion RMB to help developing countries affected by global warming.
While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China's commitment to fighting climate change and pointing fingers, and start shouldering their due responsibilities instead.
1.China is self-motivated to fight against climate change in order to_____
A.top the world B.transform its economic pattern
C.solve its population problem D.respond to pressure from developed countries
2.The underlined word "it" in paragraph 7 refers to _____
A.China B.the United States
C.economic expansion D.the population base
3.It can be inferred from the text that_______
A.China will completely use non-fossil fuels by 2030
B.China will carry out its plan by stopping its development
C.Chinese emit more greenhouse gases than Americans on average
D.some developed countries are not taking on their due responsibilities
4.Which of the following is a sign of China's self-motivated fight against climate change?
A.Expanding its economy
B.Using non-renewable energies.
C.Making it part of China's 13th Five-Year Plan.
D.Donating money to developing countries
