During a research experiment a marine biologist placed a shark into a large holding tank and then released several small bait fish into the tank.
在一个研究实验中，一个海洋生物学家把一条鲨鱼放进一个大的水箱中，然后投放了一些小的诱饵鱼进去。
As you would expect, the shark quickly swam around the tank, attacked and ate the smaller fish.
你可能已经预料到了，鲨鱼快速地在水箱里四处游动，攻击并吃掉了那些较小的鱼。
The marine biologist then inserted a strong piece of clear fiberglass into the tank, creating two separate partitions. She then put the shark on one side of the fiberglass and a new set of bait fish on the other.
然后海洋生物学家将一面强韧的透明纤维玻璃插入到容器中，创建了两个单独的分区。然后，她把鲨鱼放在纤维玻璃的一边，另一边是一组新的诱饵鱼。
