He is not ( ) to be present at the

He is not ( ) to be present at the
He is not ( ) to be present at the meeting tonight
A、possible
B、likely
C、probably
D、perhaps
选哪个?为什么

选B.因为主语是人称,经常用 be likely to“有可能”的意思.而其它几个词虽然具有“有可能”,但不用于人称后面,只能用于,it is pobbile that he will be present at eh meeting tonigh.这类句式.
be likely to 倒是可以用it is likely that .
