Identifying young people with the potential to be great athletes has become a serious, business around the world. Many countries, including Australia, have sophisticated(复杂) programs for identifying and nurturing(培养) talent.

The AIS (Australian Institute of Sport) already runs a program that identifies potential winners starting from the age of 12 based on their physical and physiological(生理的) abilities.

Could genetics improve these programs? The problem is that no one gene test is ever going to do an accurate job of identifying someone with the physical attributes of a sporting champion, says Professor North.

"We can think of the elite athlete as what I'd call a complex phenotype(表现型)," she says. “There are going to be a large number of different genes involved. Any one single test is unlikely to be highly predictive.”

Professor Peter Fricker, director of the AIS, agrees. Although he is intrigued in the possibilities of genetic testing, he says using such tests to identify athletes would be difficult. "The feeling I have is that it won't be that easy," he says. "Talent selection is not just about your genes."

Since 2004, the AIS has been forbidden by government from any involvement in genetic work, including genetic testing. But Professor Fricker thinks that is likely to change in the near future. "There's been a shift in view more recently," he says.

When it does, the AIS will resume its work on the genetics of sports performance, Professor Fricker says. They would be particularly interested in looking for more genes that might help shape elite performance, but also for genes that increase the risk of injury.

Last year, the Human Genetics Society of Australasia issued a position statement on gene testing for sport, after concerns that people could use tests to steer children into particular sports.

“The Human Genetics Society thinks there are not enough data to use these tests for determining what sport kids should do,” said Professor David Thorburn, president of the society.

He stressed that genetic tests should not be performed on children, except in very specific medical circumstances.

57.The aim of the AIS’s program is to        .

A.predict how genes are connected with injuries

B.find potential great athletes

C.find out what qualities a professor has through gene tests

D.turn an athlete into a champion by transferring genes

58.By saying “Talent selection is not just about your genes”, Fricker means         .

A.effort is more important than genes in most cases

B.you can’t choose an athlete just depending on genes

C.to research one’s genes takes a long time

D.most people don’t believe in genetic tests

59.The underlined word “resume” in Para. 7 can be replaced by              .

A.stop B.complete   C.reduce      D.continue.

60.What’s Professor David Thorburn’s attitude towards genetic tests?

A.Genetic tests have a negative effect on children.

B.Genetic tests, under certain conditions, can be conducted on children.

C.Genetic tests can reduce the risk of athletes’ injuries.

D.People could use genetic tests to decide what sport kids should take.

I don’t really care how many claws the animal in a comic book (漫画书) has. I’m not overly concerned whether the bird is colored green or grey. In fact I don’t think comic book “collector” really applies to me at all. I’m probably more of a comic book “appreciator”. My interest has always been in what can be accomplished with the medium of “visual story - telling”. In the respect, comic books are the best thing going. And there are some great comics out there.

I’m not sure exactly where this interest of mine came from. I do know that as a child, comic books allowed me to improve my reading – skills. The Mighty Thor made me develop an interest in Norse legends; Challengers of the Unknown got me interested in science fiction. The combination of words and pictures was a perfect springboard (起点) for my childhood imagination.

So just how does one learn to appreciate comic book art? There is a classic example. Writer Scott Macloud was philosophical (达观的) about what makes a comic book stand out in his best – selling book Understanding Comics. The book, first published in 1994, has been translated into 13 languages and is practically useful for students studying graphic illustration (图示说明).

On the Internet there are some cool comic book sites to be found. More than a few are mainly about superheroes and the like. But there are some choice sites that I would describe as “literary (文学的),” in that you can find some great resources that discuss the comic book as an art form. Among them there is a great article and interview at www.rcharvey.com discussing the influence of several artists and writers in the field.

Check it out. Spend two dollars on a comic book and read it with your children. You may find yourself enjoying what you see and read. You may even find yourself wanting more.

And wanting to read more is a good thing!

53.According to Para. 1 the author is concerned about          .

A.the color of the characters in a comic book

54.What do we know about Scott Macloud’s best – selling book?

A.There are many classic examples if comic books in it.

B.It is helpful 1 for students studying science fiction.

C.It suggests what good comic books are like.

D.It is mainly intended for parents.

55.In the passage, the author encourages people to         .

A.follow the example of superheroes from comic books

B.join in the discussion at www.rcharvey.com

One warm day when I was walking in my backyard, I saw a pinecone(松球) on the ground. I picked it up, and some seeds fell out of it. Those seeds would be a tasty treat for a squirrel (松鼠).

I realized that pinecones were not always open like this one. Sometimes cones were tightly closed. I decided to find out why.

I gathered pinecones from my backyard. I watched them for over a year. Here’s what I learned.

Pinecones open and close slowly as the weather changes. When it’s cold or wet, cones are tightly closed. This protects the seeds inside from rain and snow.

When the weather becomes warm and dry, pinecones open. On a hot day, you might even hear the sound of cones popping open. The seeds inside may then fall to the ground. The wind may blow the seeds to places where they can grow into new pine trees. A seed has a better chance of taking root and growing when the weather is warm.

“Pine seeds are an important source of food for many animals,” says Monty Maldonado. He is a pinecone expert with the United States Forest Service. He says squirrels depend on pinecone seeds for most of their meals. They spend lots of time gathering and storing the cones. Maldonado says some animals eat only the seeds from a pinecone. But red squirrels and gray squirrels will eat the whole thing.

Small animals aren’t the only creatures that eat pine seeds. Maldonado says big grizzly bears (灰熊) and people eat them, too.

Seeds inside a pinecone are important for the growth of new trees and as food for animals. It is the pinecone’s job to protect them. So take note of the pinecones you see on the ground. They hold treasures inside.

45.According to the passage, when it is rainy, cones          .

A.are open   B.are usually shut       C.grow quickly    D.stop growing

46.According to Monty Maldonado,        .

A.not all squirrels eat the whole pinecone        

B.pine seeds are difficult to find for many animals

C.people in the forest are sometimes attacked by grizzly bears

D.most small animals depend on pinecone seeds for their meals

47.We can learn from the passage that on sunny days         .

A.seeds may fall out of the cones      

B.squirrels stay still in their nests      

C.it’s difficult for a seed to take root

D.the wind will put the pine trees in danger

48.In the last paragraph, the author points out that         .

A.more and more new trees need to be planted in future 

B.people should be responsible for protecting animals

C.people should be careful not to damage the pinecones  

D.squirrels now have few seeds to feed themselves

49.Which of the following is TRUE according to the passage?

A.The author learned why pinecones are not always open in the forest.  

B.The author gathered pinecones and observed them for a month.  

C.The author is fond of gathering and storing the cones.

第一节:阅读下列短文,从每题所给的四个选项(A,B,C和D)中,选出最佳选项。

Trouve sat up on its back legs arid growled(吼叫)the words “How are you, Grandmama?” The audience roared with laughter and clapped. Twenty-year-old Aleck gave the dog a morsel(一口)of food. His hard wok paid off. His dog could talk!

Aleck was fascinated with the different sounds of people’s speech. His father taught students who had a speech problem to improve their speech. Aleck paid close attention. Could an animal form sounds into words, too? He decided to experiment with Trouve, the family dog.

The easy part was teaching Trouve to growl whenever Aleck wanted. The little dog growled for a morsel of food.

Next Aleck moved the dog’s “lips’ as it growled. It sounded like “ma ma ma.” Trouve learned quickly to stop the growling just as Aleck’s hand moved away. They practiced and practiced until the dog said “ma ma” perfectly.

Soon Aleck discovered more. If he pushed gently under the dog’s jawbone(下颚骨), it made the “ga” sound. If he pushed once and moved the dog’s lips twice, he could make the dog say, “ga ma ma”. With even more practice, it sounded like “grandmama.” Whenever Trouve said “grandmam,” Aleck gave the god two treats, so Trouve loved the lessons.

Aleck tried to teach his dog to move its tongue. So that Trouve could say more words. That didn’t work, but Aleck didn’t give up.

After many hours of practice, Trouve could say, “Ow ah oo ga-ma-ma?” This sounded just like “How are you, Grandmama?”

Friends and neighbors traveled to see young Aleck and his amazing talking dog. Rumors spread that the dog could speak by itself, which wasn’t true. No matter how much Aleck tried, the dog was never able to move its lips without help.

Aleck’s full name was Alexander Graham Bell. He wanted to know more about the world all his life. He had many ideas. Some worked; others didn’t. But he kept trying—always learning; One of his inventions was something called the telephone.
