I recently heard a story about a famous scientist who had made several very important medical breakthroughs（突破）. He was being interviewed by a reporter who asked him he thought he was able to be so much more than the average person.

He responded that it all came from a(n) with his mother that occurred when he was about 2. He had been trying to milk from the fridge when he the slippery(光滑的) bottle, its contents running all over the kitchen floor.

When his mother came in, shouting at him or giving him a lecture, she said, “Robert, what a great and wonderful you have made! I have seen such a huge pool of milk. Well, the damage has already been . Would you like to get down and in the milk for a few minutes before we clean it up?”

Indeed, he did. After a few minutes, his mother said, “Robert, whenever you make a mess like this, eventually you have to restore everything to its proper order. So, how would you like to do that? We could use a sponge(海绵), a towel or a mop. Which do you prefer?” He chose the sponge.

His mother then said, “ You know, what we have here is a experiment in how to effectively carry a big milk bottle with two hands. Let’s go out in the back yard and fill the bottle with water and see if you can .” The little boy learned that if he the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful !

This scientist then said that it was at that moment that he knew he didn’t need to be to make mistakes. Instead, he learned that mistakes were just for learning something new, which is, , what scientific experiments are all about. Even if the experiment “doesn't ,” we usually learn something from it.

Why is setting goals important? 1. Instead of just letting life happen to you, goals allow you to make your life happen.

Successful people imagine how their life should be and set lots of goals. 2. .It’s like having a map to show you where you want to go. Thank of it this way. There are two drivers. One has a destination (目的地) in mind which can be found on a map. She can drive straight there without any wasted time or wrong turns. The other driver has no goal or destination or map. She starts off at the same time from the same place as the first driver, but she drives aimlessly around, never getting anywhere, just using up gas. Which driver do you want to be?

3. . They decide what they want in life and then get there by making plans and setting goals. Unsuccessful people just let life happen by accident. Goals aren’t difficult to set and they aren’t difficult to reach . 4. . You are the one who must decide what to achieve and in what direction to aim your life.

5. . Written goals can be reviewed regularly, and have more power. Like a contract (合同) with yourself, they are harder to neglect or forget. Also when you write your goals in a particularly way, you are able to make yourself know situations that will bring you nearer to your goal.

A. Research tells us that when we write a goal down we are more likely to achieve it

B. Winners in life set goals and follow through

C. It’s up to you to find out what your goals really are

D. It’s difficult for a driver to reach his destination without a map

E. Because goals can help you do and experience everything you want in life.

F. By setting goals you are taking control of your life

G. Goals are difficult to set and they are difficult to reach.

 

Despite the promising publishing industry in China today, many Chinese people spend little time reading. Some of them read just to kill time or prepare for the tests rather than enjoy the reading itself.

As far as I am concerned , Chinese people don’t read as much as they used to for the following reasons. For one thing, people have too much going on in their mind as China is now experiencing great changes, so it has become difficult for them to enjoy reading quietly; for another, with heavy work load, people in China only read when they need something for practical use or something relaxing to keep them away from working pressure.

Personally, reading is of great significance in life. It not only provides a source of satisfaction and pleasure, but also serves as a means to seek information and to acquire, develop and apply knowledge. Besides, people can read to enhance language proficiency and to broaden life experience as well.

I myself have improved English a lot through reading. At the beginning, I thought it difficult to read English novels but gradually, my language proficiency was enhanced before I realized it. Personally, it will make a great difference by reading.

“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from 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 cows and a cat.

They just might succeed in cloning Missy soon — or perhaps not for another five years.

Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's 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（代孕的）mother. The wastage of eggs and the many spontaneously aborted(流产，发育不全) fetuses（胎）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 1996, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research.

Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype（原型；雏形）is, by all accounts, athletic, good-natured and super-smart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament（气质、性情）. 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 clones differ from Missy.”

Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.

However, Westhusin is cautious about his work. He knows that even if he gets a dog 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.By “stupid endeavor”, Westhusin means to say that ________.

A. human cloning is a foolish undertaking

B. animal cloning is absolutely impractical

C. human cloning should be done selectively

D. animal cloning is not worth the effort at all

2.What does the second paragraph tell us about Westhusin's dog cloning project?

A. Its success is already in sight.

B. It is progressing smoothly.

C. It is doomed to utter failure.

D. Its outcome remains uncertain.

3.By cloning Missy, Mark Westhusin hopes to ________.

A. study the possibility of cloning humans

B. search for ways to modify its temperament

C. find out the differences between Missy and its clones

D. examine the reproductive system of the dog species

4.We learn from the passage that animal clones are likely to have ________.

A. a bad temper

B. defective（有缺陷的、有毛病的）organs

C. immune deficiency

D. an abnormal shape

5.What’s the best title of the passage?

A. Cloning of Missy

B. Scientist Says ‘No’ to Human Cloning

C. Human Cloning Is Dangerous .

D. Westhusin Is Cautious about Cloning
