Tom has gone out. Tom _______. A. was out B. has been out C. is off D. will be out 说明:对不起,由于匆忙,原题中的 C选项打成了 is out,其实是is off, 很抱歉!另外,我说请专家再补充的意思没说清楚,我想问的是选C 即 is off 可不可以,谢谢!
不太同意 wfyiqpl1的看法,has been out 肯定是可以说的,be out 并非表示“一个事物的特征”,它只是表示一种状态。be out 与 have been out 的区别就是它们所用时态的区别。类似的如 be ill 与 have been ill。它们与 have been beautiful的情况不一样。
