As the train moved by, the son was overjoyed with the 38 outside. “See, dad, the scenery of green trees moving 39 is very beautiful.”

This behaviour from a 40 son made the other people feel strange about him. Everyone was 41 about the son. “This person seems to be 42,” a newly-married man whispered to his wife.

Suddenly it started 43. Lots of drops fell on the travellers through the open window. The son excitedly said to his father, “See, dad, how 44 the rain is, too.” The man’s wife was annoyed by the rain drops spoiling (弄坏) her 45 suit. The young man said to the father, “Can’t you see it raining yourself? Your son 46 be mentally ill. Get him to a hospital!”

The old man 47 at first, feeling rather hurt and then replied, “We are on the way back from the 48. My son was 49 from birth. He just recovered from an eye operation yesterday. The rain and nature are all new to his eyes. Please 50 us for the inconvenience that we may have caused.”
