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 Asian 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.”
1.As is mentioned above, which factor mainly results in students' myopia in South East Asia?
A. Lack of research into the problem. B. Genetic faults of the people.
C. Elongation of the eyeball. D. The shortage of outdoor light.
2.Which of the following statements do you think Professor Morgan agrees with?
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.
3.What's the main idea of the last paragraph?
A. Short-sightedness has nothing to do with changes in gene pools.
B. Gene remains the main cause of the long-standing problem.
C. An environmental effect playing a sensitive genome counts.
D. The environment is to blame for the extraordinary rise in myopia.
4.What's the best way to take care of your eyes according to the passage?
A. Look at the sun from time to time. B. Do eyes exercise regularly.
C. Spend more time in the open air. D. Equip the classroom with better lights.

Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants (移植). However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects (排斥) the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel’s Tel Aviv University printed a 3D human heart on April 15.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” professor Tal Dvir told CNN.
Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels (血管), chambers (心室) and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb (拇指). And, although it can contract (收缩) like a muscle, it cannot pump out blood like a real one. At present, the heart prototype (样品) is like a tiny airplane that has all of the right parts, but can’t fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue (脂肪组织) into human heart tissue with stem cell (干细胞) technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.
“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized (个性化的) for every patient.”
But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice.
“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely,” Dvir said.
1.Why is the 3D-printed heart important?
A.It will be used on a patient.
B.It is the first 3D-printed heart.
C.It will replace a heart donation.
D.It has a complete heart structure.
2.What problem do 3D-printed hearts have?
A.They cost too much. B.They are too small.
C.They can’t contract. D.They are hard to produce.
3.Why would there be less risk of organ rejection with the 3D-printed heart?
A.It would be made with stem cell technology.
B.It would be made from human fat tissue.
C.It would come from a patient’s body.
D.It would be printed according to the patient’s condition.
4.What attitude does Tal Dvir hold toward the future of 3D printing of organs?
A.Confident. B.Doubtful.
C.Worried. D.Confused.

Hilversum is a medium-sized city between the major cities of Amsterdam and Utrecht in the Gooi area of North Holland,the Netherlands.Unlike most of the Netherlands,Hilversum is actually in a hilly area with the soil mostly consisting of sand.Once called the Garden of Amsterdam,it still attracts travelers to come over to cycle and walk through the surrounding forests.They visit it for a relaxing day off from the urban madness.For Dutch people,Hilversum is all about textile(纺织) and media industries,and modern architecture.
