Part A
Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)
"I've never met a human worth cloning", says cloning expert Mark Westhusin from the cramped confines of his lab at Texas A & M University. "It's a stupid endeavor.' That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two calves and expect to clone a cat soon. They just might succeed in cloning Missy later this year—or perhaps not for another five years. It seems the reproductive system of man's best friend is one of the mysteries of modem science.
Westhusin's experience with cloning animals leaves him vexed by all this talk of human cloning. In three years of work on the Missyplicity project, using hundreds upon hundreds of canine eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted fetuses may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. "Cloning is incredibly inefficient, and also dangerous", he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly, the sheep, was cloned in 1997, Westhusin's phone at A&M College of Veterinary Medicine has been ringing busily. Cost is no obstacle for customers like Missy's mysterious owner, who wishes him remain unknown to protect his privacy. He's plopped down $3.7 million so far to fund the research because he wants a twin to carry on Missy's fine qualities after she dies. But he knows her clone may not have her temperament. In a statement of purpose, Missy's owner and the A&M team say they are "both looking forward to studying the ways that her clone differs from Missy".
The fate of the dog samples will depend on Westhusin's work. He knows that even if he gets a dog viably pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems. "Why would you ever want to clone humans", Westhusin asks, "when we're not even close to getting it worked out in animals yet？"
Which of the following best represents Mr. Westhusin's attitude toward cloning？

听力原文：Q：Excuse me，may I see your boss now？

Actually the Leonardo had been gone for more than twenty-four hours before anyone noticed it was missing. The museum was always closed on Mondays for maintenance. Just before closing time on Sunday three men had entered the museum, where they had hidden themselves in a storeroom. The actual theft was quick and simple. Early the next morning Perrugia removed the painting from the wall while the others kept watch. Then they went out a hack exit.
Nothing was seen or heard of the painting for two years when Perrugia tried to sell it to a dealer for half a million lire. Perrugia was arrested on December 13th Perrugia claimed he had stolen it as an act of patriot-ism, because, he said, the painting had been looted from the Italian nation by Napoleon. Perrugia was imprisoned for 7 months. It seemed that the crime of the century had been solved.
But had it？ Perrugia was keen to claim all responsibility for the theft, and it was twenty years before the whole story came out. In fact Perrugia bad been working for two master criminals, Valfierno and Chaudron, who went unpunished for their crime. They would offer to steal a famous painting from a gallery for a crooked dealer or an unscrupulous private collector. They would then make a copy of the picture and, with the help of bribed gallery attendants, tape the copy to the back of the original painting. The dealer would then be taken to the gallery and would be invited to make a secret mark on the back of the painting. Of course the dealer would actually be marking the copy. Valfierno would later produce forged newspaper cuttings announcing the theft of the original, and then produce the copy, complete with secret marking. If the dealer were to see the painting still in the gallery, he would be persuaded that it was a copy, and that he possessed the genuine one.
Chaudron then painted not one, but six copies of the Mona Lisa, using 400-year-old wood panels from antique Italian furniture The forgeries were carefully aged, so that the varnish was cracked and dirty. Valfierno commissioned Perrugia to steal the original, and told him to hide it until Valfierno contacted him Perrugia waited in vain in a tiny room in Paris with the painting, but heard nothing from his partners in crime. They had gone to New York, where the six copies were already in store. They had sent them there before the original was stolen. At that time it was quite common for artists to copy old masters, which would be sold quite honestly as imitations, so there had been no problems with US Customs. Valfierno went on to sell all six copies for $ 300 000 each. Valfierno told the story to a journalist in 1914, on condition that it would not be published until his death.
Does the story end there？ Collectors have claimed that Perrugia returned a copy. It is also possible that Leonardo may have painted several versions of the Mona Lisa, or they might be copies made by Leonardo's pupils. There has been a lot of controversy and argument about the 450-year-old painting, but after all, maybe that's what she's smiling about.
The painting was probably stolen ______.
