The cold weather of the last week has had a surprising result. Forty thousand Russian red-necked ducks have ___1___ in Britain where the weather, just below freezing, is like spring to them.

　　The Russian red-necked ducks manage perfectly well at temperatures down to thirty degrees ___2___ zero. They wouldn't think of ___3___ home at minus forty. But, as the weather gets colder, if it docs, they make a quick ___4___ to take off together all with a single thought ____5___,“Go somewhere ____6____”.

　　Last Tuesday the small ___7___ near my house was invaded by about three hundred Russian red-necked ducks, a noisy lot, though I must say they were not troublesome. Our local birds were at first quite ___8___ by these ___9___ from far away, and there were some obvious language difficulties too. At nine o'clock I went down ___10___ to the edge of the lake, with a little bread and milk ___11___ our own birds. I saw them standing up, __12___ the foreigners to eat up everything. But my worry proved ___13__：the red-necked birds didn't like the bread at all. Many of them ___14___ a mouthful, and threw up. In fact they pushed and fought to get away from the food, ___15___ own birds looked at them ___16___.
