Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

During a research experiment a marine(海洋) biologist placed a shark into a large holding tank and then released several small fish into the tank. 【1】_______

The marine biologist then inserted a strong piece of clear fiberglass（玻璃纤维）into the tank, creating two separate parts. She then put the shark on one side of the fiberglass and a new set of small fish on the other.

Again, the shark quickly attacked. This time, however, the shark hit the fiberglass divider and bounced off. 【2】_______ Meanwhile, the small fish swam around unharmed in the second part. Eventually, about an hour into the experiment, the shark gave up.
This experiment was repeated several dozen times over the next few weeks. 【3】_____ Eventually the shark got tired of hitting the fiberglass divider and simply stopped attacking altogether.

The marine biologist then removed the fiberglass divider, but the shark didn’t attack. 【4】_____ So, they swam wherever they wished, free from harm.

Like the shark in the story, many of us, after experiencing setbacks and failures, emotionally give up and stop trying. 【5】____ In other words, we continue to see a barrier in our heads, even when no ‘real’ barrier exists between where we are and where we want to go.

A. At the same time, the shark tried again and again.

B. We believe that because we were unsuccessful in the past, we will always be unsuccessful.

C. The shark was trained to believe a barrier existed between it and the small fish.

D. It kept repeating this behavior every few minutes fruitlessly.

E. We should keep on trying even if we meet obstacles.

F. Each time, the shark got less aggressive and made fewer attempts to attack the small fish.

G. As you would expect, the shark quickly swam around the tank, attacked and ate the smaller fish.

Answer 1

【答案】

【1】G

【2】D

【3】F

【4】C

【5】B

【解析】

试题分析: 本文主要通过一位海洋生物学家做的关于鲨鱼攻击玻璃纤维的实验来说明人们往往和鲨鱼一样，在遇到阻碍时，尝试几次没有成功就放弃了，但是当阻碍没有了，人们还是没有继续前进，因为人们往往把一些不存在的阻碍当成是阻碍。

【1】G 考查对上下文语境的理解。空前的意思是：海洋生物学家把一些鲨鱼放到大的水缸里，把一些小鱼也放到水缸里。所以这里选G（正如你所预料的那样，鲨鱼很快的在水缸周围游，攻击并且吃小鱼。）与上下文一致。

【2】D 考查对上下文语境的理解。空前的意思是：然而，这一次，鲨鱼撞到了玻璃纤维然后反弹；空后的意思是：同时，一些小鱼在另外一部分没有受到伤害。所以这里选D（鲨鱼每几分钟徒劳的重复同样的动作。）与上下文一致。

【3】F 考查对上下文语境的理解。空前的意思是：在接下来的几周这个实验被重复了几十次。空后的意思是：最终鲨鱼疲于撞击玻璃纤维，停止攻击。所以这里选F（每一次，鲨鱼的攻击性减弱了，也减少了攻击小鱼的次数。）与上下文一致。

【4】C 考查对上下文语境的理解。空前的意思是：海洋生物学家然后把玻璃纤维搬走，但是鲨鱼不再攻击了。空后的意思是：所以它们很自由，如愿的游着。所以这里选C（鲨鱼被训练的相信鲨鱼和小鱼之间有障碍。）与上下文一致。

【5】B 考查对上下文语境的理解。空前的意思是：就像鲨鱼一样，我们许多人在经历了挫折和失败后，情感上就放弃了。所以这里选B（我们认为我们在过去没有成功，我们不会成功。）与上下文一致。
