Having two eyes instead of one is particularly useful for ______ .
选项 A、seeing at night
B、seeing objects far away
C、looking over a wide area
D、judging distances
答案D
解析 细节题。第五段的第一句话和最后一句话给出了答案：“Having two good eyes is important for judging distances．”和“People who have only one eye can not judge distance as people with two eyes can．”由此可以得出用两只眼睛代替一只眼睛最关键的是帮助人们判断距离。
