2、So the researchers tested whether the birds could store and recover a tool so they could get it at their food after a gap of 17 hourssomething we wouldnt expect them to do naturally.But they were able to instantly select the tool out of a number of unnecessary items.In another experiment,the researc
3、hers taught crows to select a token(代币) from a number of items so that they could then exchange for food.Again,the birds then showed that they could plan for the future using this new behaviour.This is different from all of the previous studies in future planning,which have focused on naturally occu
4、rring behaviour.For example,we know that chimpanzees select,transport and save appropriate tools for future needs.These studies have shown that animals can plan for the futurebut they left an important question open for debate.Are animals only able to plan to use abilities that have evolved to give
5、them a specific advantage,or can they flexibly and intelligently apply planning behaviour across various actions?Most critics would say the former,as the animals were tested in naturally occurring behaviours.But the new research provides the first evidence that animal species can plan for the future
6、 using behaviour that doesnt typically occur in nature.This supports the view that at least some recognitive abilities in animals dont evolve just in response to specific problems.Instead,it suggests that animals can apply these behaviours flexibly across problems in a similar way to humans.We need
7、to investigate how flexible behaviour evolved.Then we might be able to see how crows ability to plan for the future fits in with their broader cognitive powers.1Whats the new finding about some crows according to Paragraph 1?AThey can store food.BThey can use tools to recover food.CThey can store an
8、d recover tools.DThey can select and store food.2What are crows trained by scientists to do when given a token?AReject it casually. BExchange it for food.CSave it as their food. DBuild a nest with it.3What do scientists think of the studies that animals can plan for the future?AThey are controversia
9、l. BThey are disappointing.CThey are contradictory. DThey are convincing.4What can be inferred about recognitive abilities in animals?AThey develop only with age.BIt is unclear how theyve evolved now.CNo animals but crows benefit from them.DPlanning for the future helps their evolution.完形填空(2017江西九江
