In Asia, the percent of the students whose eyes are being damaged is______.
The strong emphasis on educational achievement in China, Japan and other parts of South East-Asia may be coming at a heavy price.(1)Researchers say that hard work at school plus the lack of exposure to outdoor light is damaging the eyes of almost nine out of ten students—with one in five at serious risk of visual impairment and blindness. The scientists say that young people need up to three hours a day of outdoor light, but many infants are also missing out as they nap during lunch time. Dr. Ian Morgan, the lead author of the study, stated: We’ve got the massive educational pressures and we’ve got the construction of a child’s day in a way that really minimizes the amount of time they spend outside in bright light.
The scientists say that genetic factors, long thought to play a big role in short-sightedness, are not as important as the environment. They point to Singapore as a place with several distinct ethnic groups, all of whom are now suffering high levels of short-sightedness. The authors suggest that required time outdoors should be considered by educational authorities across South-East Asia as a way of dealing with the problem.
选项
A、genetic factors play a more important role
B、environmental factors play a big role
C、both genetic factors and environment do harm to people
D、both genetic factors and environment have something to do with short-sightedness
答案
B
解析
语义理解题。句(3)中,首先介绍了科学家们认为环境是导致近视的重要因素,基因在其次。接着用新加坡是一个多种族的国家,可同样饱受着高近视率折磨的例子来证明上述结论。所以答案为B。
