问题     German zoologist Randolf Menzel says bees aren’t as busy as people believe they are. "Bees are not particularly【C1】______. Instead they sleep a lot and are lazy. They spend【C2】______80 per cent of the night sleeping. Even during the day they often fly to the nest【C3】______they rest their wings. " said Menzel, a zoologist at the Free University in Berlin, who has studied bees for four decades. But to【C4】______for their apparent laziness, they are actually very intelligent. They are【C5】______learners and able to recognize various smells.
    Menzel said bees’ learning, like【C6】______of many animals, was based on a reward system. "If a bee is rewarded once for something, it remembers it for a week. But if it is rewarded three times, it will remember it for its【C7】______lifetime. " Said Menzel. He last week was awarded a【C8】______by the German Zoological Society.
    The memory capacity of bees means they can【C9】______among more than 50 different smells to find the one they want. "What is interesting is that what smells good to a bee, is also a【C10】______smell for humans. " said Menzel.
【C5】

选项 A、rapid
B、swift
C、speedy
D、quick

答案D

解析 四个词都有“快的,迅速的”的意思,但其意义各有侧重点。rapid多指“运动本身",迅速的,以极高速度运动,例如:a rapid river湍急的河流;swift指“快速的”,但经常含有“灵巧的,优美的,不费力的”意思,指运动的流畅性与稳定性;在很多场合,可与quick、fast通用,但swift带有文学意味,是比较正式的用词,例如:The expreSS is as swift as an arrow.快车似箭一般地飞驶。speedy含有“时间快、速度快并且迅速把事情办好”的意思,如:aspeedy fight速战;quick指“用较短的时间或在较近的将来动作或理解迅速的”,例如:a quick reply一个迅速的回答。从此句意来看,他们学习东西很快,能够辨别出各种各样的味道。因此,D最为合适。
