星期天,我和妈妈去奶奶家。路上,我看到村口两棵垂柳的“头发”随风飘动,觉得很漂亮,便走近去瞧。呀!一些柳叶上有奇怪的圆球,有的叶片上竟然长了两个圆球。这些圆球有绿色的,也有红褐色的。这是怎么回事?我一脸疑惑地请教妈妈。妈妈说她以前从没发现这个现象,也不知道是怎么回事。 Sunday, my mother and I go to my grandmother’s house. On the road, I saw the “hair” of two weeping willows at the entrance of the village fluttered in the wind and felt very beautiful. Then I went to look at it. Some of the willow leaves have strange balls, and some even have two balls on the leaves. The balls are green and reddish-brown. What’s going on? I asked my mom about the question. Mom said she had never discovered this phenomenon before and I did not know what was going on.
