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.
【C2】
选项 A、as to
B、as much
C、up to
D、such as
答案C
解析 四个词组的意思分别是：as to关于，至于；as much同样多；up to多达，到……之多；such as诸如……，像……那样的。此句子的意思是：晚上它们80%的时间都在睡觉，这里需要一个修饰时间量的介词短语，因此C是正确答案。
