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. |
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. |
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. |
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. |

The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age.

We all know that if we want to keep our body in good shape we have to do physical exercise regularly as well as be careful with what we eat.

Here"s some advice about how to choose the right diet to keep your eyes healthy.
— Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots,oranges,pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids,which help to maintain good vision.
— Include dark green vegetables,such as spinach (菠菜) and broccoli (西兰花) in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block (阻挡) the damaging UV radiation(紫外线辐射)from the sun"s rays.
— Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are necessary to good eye health.
— Increase your intake of omega3 with some sea fish, and some other seafood. Omega3 helps build cell walls and is especially beneficial to keeping eyes healthy .It also helps regulate the eye"s internal pressure and helps the eye dry up excess fluid.

The young student was experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the great nervousness. though poor scores are often a result of poor study habits, sometimes test anxiety causes low scores. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
Special university counseling(咨询) courses try to help students. In these courses, counselors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the test shows their anxiety is high, the students can take courses to help them deal with their nervousness. These courses teach students how to relax their bodies. By controlling their nervousness, they can let their minds work at ease, learn information, then come out without difficulty in a test.
An expert at the University of California explains, "With almost all students, relaxation is felt after taking our program. Most of them have better control during their test. Almost all have some improvements. For some, the improvement is very great.
