天山5(GWD13)的第11题

以前没有讨论过的

Q11：A south American bird that forages for winged termites and other small insects while swinging upside down form the foliage of tall trees, the graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that is represented in virtually every kind of habitat.

我把正确答案打上去了。划线部分应该是bird的定语从句吧。哪位nn能帮我翻译下：while swinging upside down form the foliage of tall trees??这句话我不知道什么意思。我猜测是不是form应该改为from.要不说不通。

swing upside down from the foliage of tall trees

从很高的树的枝叶上翻身（upside down 大头朝下）飞下

谢谢joe11gg,看来是form这个单词错了。应该是from：）
