“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 13yearold 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 modern 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 to 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？”

Global warming could make humans shorter, warn scientists who claim to have found evidence that it caused the world’s first horses to shrink nearly 50 million years ago.
In fact, a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammals — horses, in this case, the last time the world heated up.
The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago.
As temperatures went up, their size went down, and vice versa (反之亦然); at one point they were as small as a house cat, said Dr Jonathan Bloch, curator (馆长) of the Florida Museum of Natural History, was quoted by the Daily Mail as saying.
The scientists say that the current warming could have the same effect on mammals — and could even make humans smaller.
“Horses started out small, about the size of a small dog like a miniature schnauzer (雪纳瑞犬). What’s surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that exactly corresponds to the global warming event, followed by cooling. It had been known that mammals were small during that time and that it was warm, but we hadn’t understood that temperature specifically was driving the evolution of body size，” Dr Bloch said in the Science journal.
1.How did the scientists find out the evolution of horses?
A. By using fossils.
B. By following the horses.
C. By heating up.
D. By studying cats.
2.What does the underlined word “miniature” in the last paragraph probably mean?
A. Small. B. Large.
C. Natural. D. Gentle.
3.What can we learn from what Dr Jonathan Bloch said?
A. As temperatures went down, the size of horses went down.
B. Horses first appeared small, then smaller and then became big.
C. Horses’ becoming smaller was connected with the global cooling.
D. Horses will be as small as a house cat in the end.
4.What would be the best title for the passage?
A. Global warming could make humans shorter
B. Scientists from Florida and Nebraska
C. Horses used to be like cats
D. Dr Jonathan Bloch
I think people everywhere dream about having lots of money. I know I do. I would like to earn large amounts of money. You can win a large amount of money in the United States through lotteries. People pay money for tickets with numbers. If your combination of numbers is chosen, you will win a huge amount of money — often in the millions.
A few years ago, my friend Al won the lottery. It changed his life. He was not “born with a silver spoon in his mouth”. Instead, my friend was always short of money. And the money he did earn was chicken feed.
Sometimes Al even had to accept handouts (施舍物) from his friends. But do not get me wrong. My friend was always very careful with the money he spent. In fact, he was often a cheapskate. He did not like to spend money. The worst times were when he had no single penny left.
One day, Al scraped together a few dollars for a lottery ticket. He thought he would never gain lots of money unexpectedly. But his combination of numbers was chosen and he won the lottery. Al was so excited. The first thing he did was buy a costly new car — one thing that he normally would not buy. Then he started spending money on unnecessary things. It was like he had “money to burn”．
When we got together for a meal at a restaurant, Al paid every time. He would always tell me the money made him feel like a millionaire. But, Al spent too much money. Soon he was “down and out” again. He had spent his “bottom dollar” — his very last amount. He did not even save any of the money.
I admit I do feel sorry for my friend. He had enough money to “live like a king”. Instead, he was back to “living on a shoestring” — a very low budget. Some might say he was wise about small things, but not about important things.
1.What does the author desire to do like others?
A. To combine the numbers perfectly.
B. To make a huge fortune.
C. To be chosen for selling lotteries.
D. To get in touch with millionaires.
2.Before Al won the lottery ________.
A. he spent too much money buying chicken
B. he didn’t value the money he had earned
C. he had trouble feeding his family
D. he hated to give a hand to his friends
3.What does the fourth paragraph imply?
A. Al always had good luck in life.
B. Al valued his money above his life.
C. Al had loved the expensive car probably.
D. Al pretended to have more money.
4.When a person is “down and out”， ________.
A. he is as poor as a church mouse
B. he lives a life like other people
C. he has set aside all his money
D. he is looking forward to big success
The young man arrived on the Massachusetts beach early carrying a radio, a shovel (铁锹), and a strange set of tools: a brick layer’s trowel, a palette knife, spatulas, spoons, and a spray bottle.
He walked down near the water — the tide (潮水) was out — and switched on the radio to listen to soft rock. Then he shoveled wet sand into a pile nearly four feet high and as many feet across. Then he created a square shape.
After that, he set to work with palette knife, spatulas, and spoons. He shaped a splendid tower, topped walls, fashioned beautiful bay windows, and carved (雕刻) out a big front gate.
The man knew his sand. He smoothly finished some surfaces and carved artistic designs on others. As the shapes began to dry, he gently kept them slightly wet with water from the spray bottle, in case they might break in the wind.
All this took hours. People gathered. At last he stood back, obviously satisfied with a castle worthy of the Austrian countryside or Disneyland.
Then he gathered his tools and radio and moved them up to drier sand. He had known for a while what many in the crowd still ignored: the tide was coming in. Not only had he practiced his art with confidence and style, he also had done so against a powerful, irresistible (不可抵抗的) deadline.
As the crowd looked on, water came at the base of the castle. In minutes it was surrounded. Then the rising flood began to eat into the base, walls fell, the tower fell, and finally the gate fell. More minutes passed, and small waves erased bay windows — soon no more than a small part was left.
Many in the crowd looked terribly sad; some voiced fear and discouragement. But the man remained calm. He had, after all, had a wonderful day, making beauty out of nothing, and watching it return to nothing as time and tide moved on.
1.In this passage, why did the young man start early in the day?
A. He needed the sun to help dry the sand.
B. It gave plenty of time for the crowd to gather.
C. He knew the tide was out on this particular morning.
D. It was easier to begin his work with only a few people around.
2.In this passage, what does the incoming tide signal?
A. It is time to begin working.
B. It is the end of a day’s work.
C. It is the busiest time of the day.
D. It is time for lookerson to leave.
3.How did the lookerson react when the tide began to come in?
A. They were disappointed to see the art ruined.
B. They tried their best to save the sand castle.
C. They were nervous about their own belongings.
D. They helped the artist finish the castle.
4.We can tell that the young man’s reward for his work is ________.
A. payment for his work
B. personal satisfaction
C. popularity as an artist
D. attention from the crowd
