问题选择题

货币的本质是

A．一般等价物

B．劳动产品

C．流通手段

D．价值尺度

答案

答案：A

题目分析：货币是从商品中分离出来固定地充当一般等价物的商品。自货币产生后，货币可以衡量一切商品价值的大小且可以和其他一切商品相交换。由此可见，货币的本质是一般等价物。A项符合题意，可以入选；C、D两项是货币的基本职能，是货币本题的体现，不能入选；劳动产品不一定是商品，故B项不能入选。因此，答案是A项。

完形填空

Once, a circle lost a piece of its own. The circle wanted to be whole, so it went around, looking for its   41  piece. But because it was not complete, it could only roll (滚) very slowly. It enjoyed the flowers and the sunshine   42  the way. It talked with worms. It found lots of different pieces, but   43  of them fit. So it left them all by the side of the road and kept on   44  for the lost piece. Then one day the circle found a piece that fit   45 . The circle put the piece into   46  . It could be whole with nothing lost. It was so happy and began to roll. As it was a perfect circle, it could roll very fast, too fast to see flowers or talk to worms. It realized how different the world was when it rolled so quickly. It felt so sad   47  it stopped, left its found piece by the side of the road and rolled very slowly.
Sometimes we are perfect when we lose something. A man who   48  everything is poor in some ways. He will never have hopes, dreams or something   49 . He will never know someone loves him or someone is giving him something he has always wanted or never had.
We couldn’t be perfect. But we must be brave enough to love, strong enough to forgive, kind enough to share   50  with others and clever enough to know there is enough love around us and then we can always have a wonderful time in our life.
