问题补充：

He is not to be present at the meeting tonight.

A. possible

B. likely

C. probably

D. perhaps

答案：

A. possible

(答案→)B. likely

C. probably

D. perhaps

解析：考查近义词辨析：这几个词都是“可能”的意思，但perhaps，probably是副词，possible，likely是形容词，但用法也不尽相同，possible可以用于形式主语it的句型：it is possible to do sth/that从句，likely可以用于sb/sth is likely to do句型或It is likely that句型。这句话的主语是he，用likely。句意：他今天晚上不可能出席会议。选B。
