缺词填空。
I have lived in the countryside since I was a child. There were many k 1 of birds there when I
was young. Every morning, lots of sparrows liked singing and j 2 in the trees outside my window,
while the swallows were busy flying out to f 3 food for their babies. Sometimes in the afternoon, I
could even see eagles f 4 in the sky.
After twenty years, many of them cannot be seen now. I can seldom see the eagles o5 the
swallows. The n 6 of the sparrows is getting smaller. Only some of t 7 sing in the morning.
Why do the birds leave here? First I think it is because the environment is becoming worse now.
The birds can't find e8 food for themselves and their babies. Second I think it is because people
often k 9 them for food.
Without the birds around, we won't feel happy any more. So we must p 10 them. Why don't we
do something to help today?
