分析 这篇短文作者通过一个实验，告诉了我们在我们的眼睛上有一个盲点，并重点解释了造成这一现象的原因．

解答 答案：66．B  细节理解题．根据第一段句子It seems to be strange to you that there is a blind spot （盲点）on the eyes．你似乎觉得很奇怪，在眼睛上有个盲点，可知很少有人知道眼睛上有盲点．故选B．
67．D   词义猜测题．根据下文But if you move the card nearer to your face，the letter will be seen again，但如果你移动卡片靠近你的脸，将再次看到字母，可知上文说的是当你慢慢地向你移动卡片，会发现字母L消失．所以此处disappear指的是让某物消失，故选D．
68．C   细节理解题．根据最后一段第一行句子When the image （影像） of the letter falls on the blind spot，it won't be seen．当这个字母落在盲点上的时候，它将不能被看到．故选C．
69．⑥④①③⑤②细节排序题．根据第二段内容及其第一、二行句子Make a card about the size of a postcard and write two English letters L and R on it，做一个明信片大小的卡片，然后写上两个英文字母L和R．hold the card about 80 cm away．控制卡片大约80厘米远．Then close your right eye and look at the letter R only with your left eye．然后闭上你的右眼只用左眼看这个字母R．as you move the card slowly towards you．你慢慢的朝你移动卡片．可知正确顺序是⑥④①③⑤②．故答案为⑥④①③⑤②．
70．A 主旨归纳题．根据这篇文章内容及其第一段句子It seems to be strange to you that there is a blind spot （盲点）on the eyes．你似乎觉得很奇怪，在眼睛上有个盲点．可知这篇短文主要告诉了我们在我们的眼睛上有一个盲点，故选A．
