问题     Human beings act in a different way from that of animals just because they can speak while animals cannot. Even the cleverest animals cannot do things which to us seem very simple and which small children, as soon as they learn to talk, would be able to do.
    A German scientist, who made experiments for many years with big apes, found that his apes could use sticks as tools to pull down bananas which they could not reach. But they only used the stick to get a banana when both the stick and the banana were in view at the same time. If the banana was in front of them and the stick was behind them, they could not use the stick. They could not bear the banana in mind long enough to look around and pick up the stick and then use it.
    The reason for this is clear. We have words for banana and stick which help us to think about these things when they are not in sight. Even a small child knowing the words "banana" and "stick" has an idea of their relationship and is able to think of "stick" together with "banana" and to remember this long enough to pick the stick from behind and use it on the banana.
    Unable to speak, animals cannot keep their knowledge of things for long. That is why they often interrupt one line of action to something else and later forget it completely. Human beings, on the other hand, use language and are able to go after one thing continuously and do it with a definite aim.
From the passage, we can learn that the reason why the ape could not get the banana if the stick was behind him while the banana was in front of him is______.
选项 A、that the ape was unable to find where the stick was
B、that the ape forgot about the banana when it turned around to find the stick
C、that the ape didn’t see the banana and the stick in the meanwhile and it couldn’t remember the banana long enough to get the stick and use it
D、that the ape was not clever enough to catch sight of the banana and the stick at the same time
答案C
解析 本题问我们可以从本文中了解到如果香蕉在大猩猩的前面，而棍子在其后面，它们便不会用棍子，究其原因是什么。根据文章第二段结尾部分的内容：如果香蕉在大猩猩的前面，而棍子在其后面，它们便不会用棍子。因为动物不能说话，所以不能长久记住香蕉，以便寻找并拿起棍子再使用它。因此，本题的正确答案应是C。
