1. 阅读下列短文，根据短文内容选择最佳选项。

My mum loves to feed birds. She puts a birdfeeder(鸟食槽) in the big tree in front of our house. Then, she waits for the birds to come. She enjoys watching all the birds coming to cat there.

There was once a problem, though. Every year two squirrels(松鼠) came and stole(偷) all the bird food. It really frustrated my mum. "Why do they think they can steal all the bird food?" she said. "If I wanted to feed them, I would set up a squirrel feeder. "

Over the years, Mum has tried every way in the book to keep the squirrels away. But squirrels have a lot of talent. Mum once put up a fence(栅栏). But the squirrels just found a way to jump over it. It seemed Mum wouldn't win.

Mum didn't give up easily, though. Two weeks ago, she went on the Internet and read all about the problem with squirrels stealing from bird feeders. She found a new way successfully. This weekend, Mum caught the two squirrels in a trap(捕捉器). She drove them outside of the city and let them go free.

Now, only birds come to Mum's bird feeder. She is happy. The birds are happy. And of course, the two squirrels are happy living in the countryside where there is always lots of food to eat. I think everyone wins.
