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.
【C1】
选项 A、working hard
B、hardworking
C、hard working
D、working hardly
答案B
解析 从此空白处可以看出，此处应该填入表语，而不能填入动词的进行时态，因为动词的现在进行时表示讲话时正在发生的动作，如果使用动词的进行时态，就说明蜜蜂正在工作，因此A和C不正确；hard可以用做形容词(坚固的，困难的)和副词(努力地，辛苦地)，hardly是副词，意思是“几乎不，简直不”。hardworking是个复合词，意思是“苦干的，不辞辛劳的”，可以作表语，故B是正确答案。
