I, who ____ your teacher, will try my best to help you with your study. [ ] A. be B. amC. are D. is

Answer 1

选B. 先行词是I, 所以用am.如：
I, who am your friend, can help you.
我作为你的朋友可以辅佐你。
I, who am your best friend, will do all that I can to help you.
我是你的好朋友，我会尽我一切所能来帮你。

Answer 2

D
虽然前面有个 I， 感觉应该跟am, 但因为从句里是who,应该跟随从句的主语。Who 是第三人称，所以用is

Answer 3

B
