arm的量词是an
Is there an arm? Yes， there is.
有一只手臂吗是的，有一只。
His arms were tied together behind his back .他的胳臂被反绑在背后。
She wanted to throw herself into his arms.她恨不得一头扑到他怀里。
Then he would beat his arms on the ground .他抡着双臂，在地上乱捶。

Infants were rent from their mother 's arms .婴儿从母亲手里被抢走。
arm的量词是a还是an
首先纠正一下，a和an它们不是量词，虽然在这里都形容手臂，都做一个的意思，但在英语里，它们的词性叫做不定冠词。那么在这道题里，要用an来做手臂的定语。因为arm的首字母是元音a，读音的音标也是元音。当单词是辅音时，就用a。如a pig.一头猪。谢谢你的提问。
