参考答案:A, C

Once upon a time there was a prince who wanted to marry a princess, but she would have to be a real princess. He travelled all over the world to find one, but    36   could he get what he wanted. There were enough princesses, but it was    37   to find out whether they were real ones. There was always something about them that was not as it    38    be. So he came home again and was sad,  39  he would have liked very much to have a real princess.

One evening a terrible storm    40   ; there was thunder and lightning, and the rain poured down in torrents. Suddenly a knocking was    41   at the city gate, and the old king went to open it. It was a princess    42    out there in front of the gate. But, good gracious! what    43   the rain and the wind had    44    her look. The water ran down from her hair and clothes; it ran down into the toes of her shoes and out again at the heels.    45   she said that she was a real princess.

“Well, we'll soon find that out.”    46    the old queen. But she said nothing, went into the bed-room, took all the bedding off the bedstead, and    47   a pea on the bottom; then she took twenty mattresses(床垫)and put    48   on the pea, and then twenty eiderdownbeds(鸭绒被)on top of the    49  .

On this the princess had to lie all night. In the morning she was asked    50   she had slept. "Oh, very badly!" said she. "I have    51    closed my eyes all night. Heaven only knows what was in the bed, but I was lying on something hard,    52   I am black and blue all over my body. It's horrible!"

Now they knew that she was a real princess because she had     53   the pea right through the twenty mattresses and the twenty eider-down beds.

Nobody but a real princess could be as    54   as that.

So the prince took her for his wife, for now he knew that he had a real princess. And the pea was put in the museum,    55   it may still be seen, if no one has stolen it.
