with a tank of air on your back ,you can
Skin-diving（轻装潜水）is a new sport today. This sport takes you into a wonderful world. It is like a visit to the moon. When you under water, it is easy for you to climb big rocks, because you are no longer heavy.
Here, under water, everything is blue and green. During the day, there is much light. When fish swim nearly, you can catch them with your hands.
When you have tanks of air on your back you can stay in deep water for a long time. But you must be careful when you dive in deep water.
To catch fish is one of the most interesting parts of this sport. Besides, there are more uses for skin-diving. You can clean ships without taking them out of water. You can get many things from the deep water.
Now you see skin-diving is both useful and interesting.
With a tank of air on your back, you can __________.
A. catch fish easily
B. stay under water for a long time
C. climb big rocks
D. have more fun
为什么选择D，不是B

我觉得是因为stay in deep water和stay under water,不是完全相同的意思.一个是强调在深水里停留,另一个只是说在水下,没有具体表明深浅.
第四个选项have more fun,虽然一下无法能找到直接的语句,但是从后两段中“To catch fish is one of the most interesting parts”,和“Besides, there are more uses for skin-diving.”以及“You can get many things from the deep water”,应该算是可以找到根据.
不过我个人认为这个题如果真的选第四,是比较缺德的出题方法,基本上就是要忽悠你,选那个看起来很像的.不是在考阅读理解的能力了,小心一点吧.
