9．Working with a group of baboons （狒狒） in the Namibian desert，Dr．Alecia Carter of the Department of Zoology，Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box．Some baboons were given the chance to watch another baboon who already knew how to solve the task，while others had to learn for themselves．To work out how brave or anxious the baboons were，Dr．Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake．
She found that personality had a major impact on learning．The braver baboons learnt，but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did．In effect，despite being made aware of what to do，they were still too shy to do what the experienced baboon did．
The same held true for anxious baboons compared with calm ones．The anxious individuals learnt the task by observing others while those who were relaxed did not，even though they spent more time watching．
This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals，something that has previously been ignored in studies on how animals learn to do things．The findings are significant because they suggest that animals may perform poorly in cognitive （认知的） tasks not because they aren't clever enough to solve them，but because they are too shy or nervous to use the social information．
The findings may impact how we understand the formation of culture in societies through social learning．If some individuals are unable to get information from others because they don't associate with the knowledgeable individuals，or they are too shy to use the information once they have it，information may not travel between all group members，preventing the formation of a culture based on social learning．

A．The design of Dr．Carter's research．
B．The results of Dr．Carter's research．

A．Those that have more experience．
B．Those that can avoid potential risks．
C．Those that like to work independently．
D．Those that feel anxious about learning．
61．Which best illustrates the"mismatch"mentioned in Paragraph 4？C
A．Some baboons are intelligent but slow in learning．
B．Some baboons are shy but active in social activities．
C．Some baboons observe others but don't follow them．
D．Some baboons perform new tasks but don't concentrate．
62．Dr．Carter's findings indicate that our culture might be formed throughB．
A．storing information

C．understanding different people

6．"Shark on the bait （诱饵）!"shouted Andre Harman，pointing to a spot a few yards behind the outboard motors． His voice gave no indication of panic，but the crew suddenly became tense and fixed their eyes on the water． Slowly，smoothly，Andre drew in the bait．The shark followed． No one asked what kind of shark it was． Everything about it，from its color to its shape，tells that it was a great white shark．
Andre lifted the bait aboard． Placing himself between the two motors，he dropped his right hand into the water just as the great head reached the first motor．"My goodness Andre!"I said． His hand seized the big nose，moving it away from the tube of the motor，guiding the shark's head up as it rose out of the water． Andre's hand held the nose，touching it gently． No one spoke． No one breathed． The moment seemed endless． In fact，it lasted less than five seconds before Andre pulled his hand back．
Still nobody spoke． Then Andre smiled and said："The first time was an accident． I was just trying to move the shark away from the motor． Sharks are attracted to motors by their electrical signals and have a habit of biting them to see if they are eatable．"Andre has worked with great white sharks for years．"My hand landed on its nose，and it sort of paused，so I kept it there，and when I did let go，the shark bit and bit as if it was searching for whatever it was that had attracted it．"
Nearly every encounter （遭遇） we had had with the great whites had been totally illogical． The more we learned，the more we realized how little was really known about them in the past years． Back then，it was generally accepted that great whites ate people by choice． Now we know that almost every attack on a human is an accident in which the shark mistakes a human for its normal food． Back then，we thought that once a great white smelt blood，it would lead to death． Now we know that nearly three-quarters of bite victims survive，perhaps because the shark recognizes that is has made a mistake and doesn't return for a second bite．

A．Andre was about to fall into the water
B．Andre was about to touch the shark
C．Andre was followed by the shark
D．Andre was bitten by the shark
61．What does the author think of the encounters with great whites？B

62． Most bite victims survive in shark attacks becauseD．
A． they are taught how to fight off sharks
B． sharks discover they are no threats
