This morning, when I was walking on the streets, I saw that two travelers were reading a map, looked puzzled. It seemed that they were lost. I went up and asked what I could help them. They told me they are looking for the Temple of Heaven. I led them to nearest bus stop and advised them to take Bus No. 20, who could take them there directly. They were appreciated my help greatly.

There is much discussion about the necessity of daily homework for students. Some say homework is necessary since only practice 1. (make) perfect, while others disagree. In my opinion, daily homework is necessary for students. However, this might be misleading that one may believe all forms of homework 2.(be) necessary. Actually, only proper amount of homework in proper form is 3. (accept); some homework may not only fail to help the students, but on 4. contrary bore them so much 5. they may lose their interest in studying. “Proper” homework, in my opinion, should vary in its forms, 6. might be some extensive reading, a paper, or even just a game, as well as other ordinary exercise. And it should leave enough 7. (free) to the students so that they could do things they really like to do with selfmotivation, rather than unwillingness. We should always remember that homework is something for us to guide the students, rather than 8. (drive) them. Only if a teacher 9. (keep) this 10. his/her mind, the homework could be of the most help to the students.

“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？”
1.Which of the following is TRUE about animal cloning?
A. Few private cloning companies could afford it.
B. Few people have realized its significance.
C. An exact copy of a cat or bull can be made.
D. It is becoming a prosperous industry.
2.From the passage we can infer that ________.
A. Mr. Westhusin is going to clone a dog soon
B. scientists are pessimistic about human cloning
C. human reproductive system has not been understood
D. rich people are only interested in cloning animals
3.Mr. Westhusin seems to believe that cloning ________.
A. is stupid and should be abandoned

C. should be taken cautiously
D. is now in a dilemma
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
