CHow long will the Chinese panda cloning project take according to the passage()

A.1 Year.
B.3 to 5 years.
C.2 years.
D.25 years.

A.
C
B.
With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the enered 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".
C.
Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine and a pioneer in embryo(胚胎) 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. "
D.
Noah’s Ark is aimed at collecting eggs, embryos, semen(精子) and DNA of enered 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.
E.
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 er of becoming extinct in the next 25 years.
F.
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.
G.
The entire procedure could take from three to five years to complete.
H.
"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 take s 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.
I.
"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. \

【单选题】DThe attitude of the author toward advertisers is (). A.appreciative B.trustworthy C.critical D.dissatisfactory

A.
D
B.
Advertisers tend to think big and perhaps this is why they’re always coming in for criticism. Their! critics seem to resent them because they have a flair for self-promotion and because they have so much money to throw around. "It’s iniquitous," they say, "that this entirely unproductive industry (if we can call it that) should absorb millions of pounds each year. It only goes to show how much profit the big companies are making. Why don’t theystop advertising and reduce the price of their goods After all, it’s the consumer who pays ... ".
C.
The poor old consumer! He’d have to pay a great deal more if advertising didn’t create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods derives largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of the ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc, from an advertisement.
D.
Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway by laws while waiting for a train Would you like to read only closely printed columns of news in your daily paper A cheerful, witty advertisement makes such a difference to a drab wall or a newspaper full of the daily ration of calamities.
E.
We must not forget, either, that advertising makes a positive contribution to our pockets. Newspapers, commercial radio and television companies could not subsist without this source of revenue. The fact that we pay so little for our daily paper, or can enjoy so many broadcast programs is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!
F.
Another thing we mustn’t forget is the "small ads. " which are in virtually every newspaper and magazine. What a tremendously useful service they perform for the community!Just about anything can be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the" hatch, match and dispatch" column but by far the most fascinating section is the personal or "agony" column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It’s the best advertisement for advertising there is!

Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. At the beginning of the 20th century there was a big farm called Hollywood. From the 1910’s to the 1950’s, Hollywood was the film center of the world.

【单选题】AThe purpose of the passage is (). A.to introduce the culture of antique clocks B.to offer some advice on collecting antique clocks C.to compare different ways to make a future profit D.to tell people...

A.

How should one invest a sum of money in these days of inflation Left in a bank it will hardly keep its value, however high the interest rate is. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.
C.
I sometimes wonder what a being from another planet might report back about our way of life. "The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound. It has a face with twelve black marks and two hands. Men can do nothing without its permission, and it fastens its young round people’s wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves. "
D.
Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time of day according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout the time. So it seems that the first clocks were human beings.
E.
However, men quickly found more convenient and reliable ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hour-glasses, and invented water-clocks. Indeed, any serious student of antiques should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.
F.
Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by the time, why not invest in air antique clock and perhaps make a future profit

【单选题】EThe underlined words "the loss" in the last paragraph refer to (). A.the money the author lost in buying the farm B.the sale of the garden in the Hollowell place C.the removal of the trees around the...

A.
E
B.
At a certain time in our lives we consider every place as the possible site(地点) for a house. I have thus searched the country within a dozen miles of where I live. In imagination Ihave bought all the farms, one after another, and I knew their prices.
C.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I had given for it.
D.
The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
E.
I was not really troubled by the loss. I had always had a garden,but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(不受约束的). It makes but little difference whether you own a farm or not.
