Every day born a decade from now will have its genetic code(基因编码)mapped at birth, the head of the world’s leading genome sequencing(基因图谱)company has predicted.

A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.

This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.

A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.

Personal genomes could also be used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.

The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.

“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.

“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.

As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.

1.In the first two paragraphs, the author mainly wants to tell us about__________.

A. the significant progress in medicine

B. the promise of a leading company

C. the information of babies’ genes

D. the research of medical scientists

2.Which of the following is a problem caused by this approach?

A. The delaying in discovering DNA.

B. The risk of developing diseases at birth.

C. The side effects of medicine on patients.

D. The letting out of personal genetic information.

3.What does the underlined sentence “… this horse is out of the barn” mean?

A. Genetic mapping technique has been widely used.

B. people can’t stop genetic mapping technique advancing.

C. People are eager to improve genetic mapping technique.

D. Genetic mapping technique is too horrible to control.

4.What’s Dr Flatley’s attitude towards the technology?

A. Tolerant. B. Conservative. C. Positive. D. Doubtful.

"Joe? Is that you?" The woman speaking to me at the baseball game looked a little familiar. "Marci?" I asked.

"It IS you!" she cried out, smiling broadly. "Gosh, it's good to see you again!"

It was good to see Marci, too. Off and on during the past few decades, I've wondered about her. I almost tried to search for her a few years ago after talking to a friend who had indicated that the 1990s had been pretty rough for Marci. So meeting her at the baseball game was really out of expectation.

We spent a few minutes talking about our lives—the good old, bad old days. Then Marci grew quiet for a moment. “You know, Joe,” she said, “ I’ve always wanted to tell you…how…how sorry I am for the way I treated you. You must have been hurt both physically and mentally.” I was a little embarrassed. I turned and looked at her. “It’s OK,” I said, “No big deal!” “But I was such a jerk.” she continued. Yes you were, I thought. “We were both pretty young,” I smiled. “I know.” she said, “It’s just always bothered me, remembering how mean I was to you. And I’ve wanted to tell you that I’m sorry.”

The expression on her face was warm and sincere. And there was something in her eyes—it looked a lot like relief. “OK,” I said. "Apology accepted!” Overcome by the sweetness of the moment, I reached an arm around her and gave her a quick hug. Just then, the crowd erupted with a huge cheer, and Marci and I both returned our attention to the game. By the time I looked over to where she had been, she was gone. But the warm, wonderful feeling of our brief exchange was still there, and continues to this day whenever I think about it .

It isn't enough to just say “I’m sorry” and "You're forgiven." But when those words are truly felt and sincerely expressed, they can open the door to miracles of the heart. Forgiveness can bring peace to an injured soul—even years after the fact. Even at a baseball game.

1.What kind of life did Marci live during the late 20th century according to the passage?

A. Happy. B. Busy. C. Hard. D. Simple.

2.What does the underlined word “jerk” in the third paragraph mean?

A. A humorous person.

B. A cruel person.

C. A careless person.

D. An honest person.

3.Why did Marci look in relief after talking with the author?

A. Because her favorite team won the game.

B. Because she learned Joe was living a good life.

C. Because she made an apology to the author.

D. Because she found she was not mean any longer.

4.What might be the best title for the passage?

A. Excitement of A Baseball Game

B. Mental Burden of A Woman

C. Miracles of Forgiveness

D. Relief of Finding A friend

In the afternoon, after divided into two groups, we began to work for the coming English speech context. Just as I was wondering what to do next, I saw a familiar figure passed by our classroom.
