单元测验

1、单选题：
​ Read the following paragraph and compare the summaries. Decide which is the best.‏​‏​Researchers in France and the United States have recently reported that baboons are able to think abstractly. It has been known for some time that chimpanzees are capable of abstract thought, but baboons are a more distant relation to mankind. In the experiment, scientists trained two baboons to use a personal computer and a joystick. The animals had to match computer designs which were basically the same, but had superficial differences. In the experiment the baboons performed better than would be expected by chance. The researchers describe their study in an article in the Journal of Experimental Psychology.‏
选项：
A:   French and American scientists have shown for the first time that baboons have the ability to think in
 an abstract way. The animals were taught to use a computer, and then had to select patterns that were similar, which they did at a rate better than chance.
B:  Baboons are a kind of monkey more distant from
 man than chimpanzees. Although it is known that chimpanzees are able to think abstractly, until recently it was not clear if baboons could do the same. But new research by various scientists has shown that this is so. 
C: According to a recent article in the Journal of Experimental Psychology, baboons are able to 
think in an abstract way. The article describes how researchers trained two baboons to use a personal computer and a joystick. The animals did better than would be expected.       --Academic writing: A Handbook for International Students by Stephen Bailey, 2006, London & New York: Routledge, p. 34
