　　参考译文
　　据报道，中国有3亿多人近视。随着越来越多的儿童患上眼疾，他们的父母希望能够通过药物、设备或通过纠正孩子读书和坐的姿势来治愈。但是实际上。对于眼睛的爱护应当从脚部的锻炼开始。3种保护眼睛的方法如下：
　　首先，不要把鞋系得太紧。试着穿宽松的袜子或在家里光脚走路。旅行的时候，尽量穿布鞋，以便使血液循环更容易些。
　　其次，踮着脚尖走路可以改善视力，并预防近视。数据表明芭蕾舞演员很少近视。
　　再次，跳绳对人的视力也有好处。跳绳的时候要反应迅速，这会使眼睛和大脑兴奋。这也有助于长得更高一些。
　　除了脚部锻炼以外，拉耳朵对视力也有好处。拉耳朵20次被发现是迅速减轻眼部压力的有效方法。
　　答案及解析
　　69．C【解析】事实细节题。从文章第一自然段第二句，…their parents hope to cure the disease by medicine，equipment or by correcting the way children read and sit暗示了当人们进行眼部保健时，很少有人能想到要进行足部锻炼。
　　70．A【解析】事实细节题。从文章第二自然段的内容可知，不要穿过紧的鞋袜，在家里可光着脚走路，旅行时穿布鞋，这就是说不要把双脚束缚得太紧，以利于血液循环。所以正确的答案为A。
　　71．D【解析】判断推理题。从文章第三自然段内容可知，踮着脚尖走可改善视力，按照常识，芭蕾舞演员是跳脚尖舞蹈的，所以可推测芭蕾舞演员很少有得近视的。所以正确的答案为D。 
　　72．C【解析】判断推理题。从文章第四段第二句话，When skipping the rope，one has to react quickly，which excites the brain as well as the eyes．可知，跳绳时会使大脑和眼睛兴奋，反应快速。所以正确的答案为C。
