题目列表(包括答案和解析)

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(障碍) 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.”
【小题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.
【小题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.
【小题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.
【小题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.

Julie, most of us are never going to achieve the heights you did as the CEO of a company.I just want to say that I was so touched by your transparency (坦诚).I haven’t been attacked publicly ever like you, but I’ve suffered from depression—just recently in fact.It helps a lot to hear personal stories, and it helped to read how you might have handled things differently.

Nancy responded on May 21, 2009

Something in Julie drew her to artwork during a very dark time in her journey.And later she stated that it’s beauty that keeps her going.Beauty and creativity can be very powerful in our lives.And it doesn’t surprise me that Julie was drawn to these naturally.Anne, maybe the artistic kinds of activities Julie used will support you well as you move beyond the depressive feelings you’re dealing with.

Anne responded on June 4, 2009

Nancy, thanks so much for taking the time to offer some great ideas for using creativity to help with depression.Actually during this time I’ve found that my creative work has been the one thing that’s brought me a lot of joy.

Nancy, thank you for your insights (深刻见解).Warmly, Julie.

完型填空

A Good Custodian

  I know a woman who tries hard to be a good custodian.I pass her every day after school as she pushes her cart down my hallway.Of course, she is my building's cleaner.

  One Tuesday morning I came into school and saw a   1   on my desk from my custodian.

  It seemed that some unbearable first year students had damaged the bathroom in a particularly disgusting way and she had been   2   to clean it.This took   3   than she had expected.She had left the typewritten note on my desk to   4   for not being able to clean my room as she was   5   to do.

  At the beginning of the period, I shared her note with my first period   6   When I mentioned that our custodian had apologized to us, their first   7   was to volunteer to seek out and beat up those first year students for making our custodian have to clean up their   8  .It turned out that just about all of my students also knew our custodian by name-all of them responded with smiles and   9   for a long time about this time or that time when she'd   10   each of them in the hallway.That she felt she needed to apologize   11   a strong reaction from many of the kids.

  As the class period was about to end, I asked them to   12   the floor like I do every period and thanked them for picking up any garbage   13   it wasn't theirs.My entire class disappeared; they each disappeared instantly   14   their desks to pick up those annoying tiny pieces of paper that   15   so easily from notebooks.One girl made a(an)  16   that I later used with my other classes:" Her job might be to clean the room, but she shouldn't have to clean up   17   us.There's a difference.”

  I believe that people know the difference between right and wrong.I believe that people appreciate it when others   18   take care of them.And I believe that people, even adolescents who are not quite yet mature, appreciate it when they see someone who takes   19   in her work.Sometimes we need a   20   of the things we take for granted...things like a good custodian to take care of us.
