题目内容
1.For better eyesight,doctors advise limiting the hours of screen time and encourage having enough eye resting time.However,another study shows that sitting in front of compute or TV screens for long hours is not the only reason for myopia (近视).An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.The research team found that there were less children who had myopia in Sydney than those in Singapore,even though they spent more time in front of computer and TV screens.The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore.Indoor and outdoor sports both make the eyes pay attention to more distant objects,which stops the eyes from changing original shape.But outdoor sports may be better than indoor sports for myopia.Because natural light is good for eye growth and vitamin D from the sunlight might be useful to it.Many doctors suggest that every child get its first eye test when he/she is about two and half years old,and even if his/her sight seems good enough.It is necessary for myopic (近视的)children to wear glasses to stop headaches,trouble reading and so on.It is also important that schools invite doctors to test their students eyes.
If that is not possible,school teachers should at least encourage parents and children to have regular eye examination and wear glasses.And parents should remember not only to limit the total screen time for their children,but also to encourage them to spend time outdoors.

A.Because the children in Sydney watch TV less.

28 D 细节题.根据第二段第四句 The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore 可知,尽管悉尼的儿童在电脑和电视机前花的时间更长,但他们的近视率比新加坡的儿童低.原因主要是悉尼的孩子们比新加坡的孩子们在户外运动上花更多时间.故正确答案为D.
29 C 细节题.根据第三段第三句 Because natural light is good for eye growth and vitamin D from the sunlight might be useful to it 可知,自然光对眼睛的成长有很好的作用,日光中蕴含的维生素D也有益于眼睛.故正确答案为C.
30 B 判断正误题.A项,根据第三段第四句 Many doctors suggest that every child get its first eye test when he/she is about two and half years old 可知,医生建议儿童在大约两岁半时就进行第一次视力检查,而不是到了上学的年纪才检查.故A项表述错误.B项,根据第三段第一句 Indoor and outdoor sports both make the eyes pay attention to more distant objects,which stops the eyes from changing original shape 可知,室内和户外运动都能让眼睛注意远处的事物,这样可以防止眼睛变形.故B项表述正确.C项,根据第三段第五句 It is necessary for myopic children to wear glasses to stop headaches,trouble reading and so on 可知,近视的儿童无论做什么事都要戴上眼镜,而不是在户外活动时不戴眼镜.故C项表述错误.D项,根据第三段第三句 Because natural light is good for eye growth and vitamin D from the sunlight might be useful to it 可知,阳光对于保护视力具有良好的作用,而不是应该限制儿童晒太阳的时间.故D项表述错误.题干要求选择正确(true)的选项,B项符合题意.故正确答案为B.
31 C 主旨题.根据全文可知,文章主要介绍了两种护眼方式:多做户外运动,减少盯着屏幕看的时间.C项意为"多做户外运动和限制看屏幕的时间都对眼睛有好处",符合主旨.A项意为"悉尼的孩子们在屏幕前呆的时间更长",这仅是科学家研究中发现的一个事实;B项意为"新加坡的孩子们喜欢室外运动",是悉尼的孩子更喜欢;D项意为"检查学生视力非常重要",本文主要不是介绍检查视力的重要性,而是要保护视力.均不符合主旨.故正确答案为C.
