孟浩然的诗《春晓》共有四句，其中不涉及生命活动、生命现象的是（　　）

   Henry works in a factory. He comes from a poor family and was in school for only four years. He has to do the hard work, but he is paid less. He likes to watch football matches very much and spends much time on them.
   One afternoon there was a big football match on the playground. He borrowed some money from his friend and hurried there. There were a lot of people there. And all the tickets were sold out. He was sorry for it. He saw a pole（杆子）outside the playground and climbed it quickly. A policeman came and said, “It is dangerous to stay on it! Come down!”“Wait a minute, please!” Henry said and just at that moment the policeman heard cheers on the playground and asked in a hurry, “Which team has kicked a goal（进球）?” “Ours!” “Wonderful! You can stay there. But take care!” The policeman said happily and left. When the match would be soon over, he came back again and asked, “Who has won?” “Theirs, 3:2.” “Come down,” the policeman said angrily. “Such a match is not worth watching!”
Henry had to come down. But soon they heard cheers again. The policeman said in a hurry, “Climb up quickly and see who has kicked a goal.”
