Up to 90% of school leavers in major Asian cities are suffering from myopia ---short-sightedness, a study suggests. Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light.
Eye experts say that you are short-sighted if your vision is blurred(模糊的) beyond 2m. It is often caused by an elongation（拉伸） of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light.
Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight helps maintain healthy eyes.
Cultural factors also seem to play a part. Across many parts of South East Asia, children often have a lunchtime nap. According to Professor Morgan they are missing out on natural light to prevent short-sightedness.
A big concern is the numbers of the students suffering from “high” myopia. One in five of these students could experience severe visual impairment(障礙) and even blindness. These people are at considerable risk—sometimes people are not told about it and are just given more powerful glasses—they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help.
For decades, researchers believed there was a strong genetic component to the condition. But this study strongly suggests an alternative view. “Any type of simple genetic explanation just doesn’t fit with that speed of change; gene pools just don’t change in two generations. Whether it’s a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn’t matter, the thing that’s changed is not the gene pool---it’s the environment.”
【小題1】As is mentioned above, which factor mainly results in students’ myopia in South East Asia?

A．Genetic faults of the people.B．Elongation of the eyeball.
C．The shortage of outdoor light.D．Lack of research into the problem.
【小題2】Which of the following statements do you think agrees with Professor Morgan?
A．A lunchtime nap is helpful in reducing myopia.
B．Glasses keep myopia from getting even worse.
C．It’s necessary to treat myopia with an operation.
D．It’s of vital importance to reduce educational pressure.
【小題3】What’s the main idea of the last paragraph?
A．Gene remains the main cause of the long-standing problem.
B．The environment is to blame for the extraordinary rise in myopia.
C．Short-sightedness has nothing to do with changes in gene pools.
D．An environmental effect playing a sensitive genome counts.
【小題4】What’s the best way to take care of your eyes according to the passage?
A．Equip the classroom with better lights.
B．Look at the sun from time to time.
C．Do eyes exercise regularly.
D．Spend more time in the open air.

Not long ago, making a baby boy or a baby girl was pretty much a hit-or-miss affair, but not any more now. Parents who have accuracy, as Monique and Scott Collins learned to their delight two years ago, when their long-wished-for daughter Jessica was born after genetic pre-screening at a fertility clinic in Fairfax, Virginia.

And baby Jessica is just the beginning. Within a decade or two, it may be possible to screen kids almost before pregnancy(懷孕) , such as how tall they are likely to be, what baby type they will have, their hair and eye color, and even their IQ and personality types.

In fact , if gene therapy lives up to its promise, parents may some day be able to go beyond weeding out undesirable trials and start actually inserting the genes they want, perhaps even genes that have been crafted in a lab. Parents may be going to fertility clinics and picking from a list of choices the way car buyers order air conditioning or wheels. “It’s the most exciting shopping” experience designing your baby.” says biotechnology（生物工藝學） critic, Jeremy Rifkin, who is concerned about the prospect（前景）. “In a society that is used  to cosmetic surgery（整形手術）, this is not a big step.”

The prospect of designer babies, like many of the ethical（倫理）problems caused by the genetic revolution, is causing the doctors, ethicists, religious leaders and politicians of the whole world to start a fierce conflict , who are trying to decide how they feel about it all.

They still have a bit of time. Apart from gender, the only trails that can now be identified at the earliest stages of development are about a dozen of the most serious genetic diseases. Gene therapy in embryos（胚胎） is at least a few years away. And the gene or combination of genes responsible for most of our physical and mental attributes hasn’t even been identified yet, so the idea of engineering genes in or out is of no practical meaning.

1.What is gene therapy supposed to do if it lives up to its promise?

    A．Screen a baby for sex.           B． Choose a baby’ s eve color.

    C． Implant genes.                  D． Identify genetic disorder.

2.According to the passage , what scientists can do with the genetic testing technology now is to_______.

    A．screen a baby’s sex             B．screen babies for desirable qualities

    C．put in genes parents want        D．craft genes in a lab

3.What can best describe Jeremy Rifkin’s attitude toward designing babies through gene therapy?

    A．Strongly supportive              B． Warmly welcome.    

    C．Uninterested.                    D． Critical.

4.From the passage we know that         .

    A．designing babies is purely scientific not to cause ethical problems

    B．designing babies may bring people a lot of ethical concerns

    C．scientists are now working against time to design babies

    D． people are concerned about the harm clone to science by designing babies

Up to 90% of school leavers in major Asian cities are suffering from myopia ---short-sightedness, a study suggests. Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light.

Eye experts say that you are short-sighted if your vision is blurred(模糊的） beyond 2m. It is often caused by an elongation (拉抻)of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light.

Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight helps maintain healthy eyes.

Cultural factors also seem to play a part. Across many parts of South East Asia9 children often have a lunchtime nap. According to Professor Morgan they are missing out on natural light to prevent short-sightedness.

A big concern is the numbers of the students suffering from “high” myopia. One in five of these students could experience severe visual impairment(障礙）and even blindness. These people are at considerable risk-sometimes people are not told about it and are just given more powerful glasses-they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help.

Whether it's a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn't matter, the thing that's changed is not the gene pool—-it's the environment."

47. As is mentioned above ，which factor mainly results in students' myopia in South East Asia?

A. Genetic faults of the people.                             B. Elongation of the eyeball.

C. The shortage of outdoor light.                          D. Lack of research into the problem.

48. Which of the following statements do you think agrees with Professor Morgan?

A. A lunchtime nap is helpful in reducing myopia.

B. Glasses keep myopia from getting even worse.

C. It's necessary to treat myopia with an operation.

D. It's of vital importance to reduce educational pressure.

49. What's the main idea of the last paragraph?

A. Gene remains the main cause of the long-standing problem.

B. The environment is to blame for the extraordinary rise in myopia.

C. Short-sightedness has nothing to do with changes in gene pools.

A. Equip the classroom with better lights.
