三、英语歌曲欣赏。

Autumn leaves are a-falling,
Red and yellow and brown.
Autumn leaves are a-falling,
See them fluttering down.
Autumn leaves from the treetops,
Flutter down to the ground.
When the wind blows his trumpet,
See them whirling around.
Autumn leaves when they're tired,
Settle down in a heap,
At the foot of the old tree.
Soon they'll all fall asleep.
