Question

请问下面的题目选A还是D？

--Is Tom at home now?
--He( ) be at home now. Because I ( )his room just now and he answered.
A. must, called B. can't phone C. may, called D. must, phoned

Answer 1

很多时候call和phone做动词都可以通用，但有些时候不通用。
比如题中的意思是打了Tom家的座机，这时候需要用call，例如：
I called his room .（只能用call，不能用phone）
I called/phoned him on his home number .（用call或者phone都可以）
总结一下，就是：
打电话给某人，两者皆可。
打电话到某地，只能用call。
