书名：是校内模拟试题第5回的incomplete sentence(应该是考古题)
页数：
题目：As a result of poor management, Sableline, a company once famous the
world over for its quality toys, is _____ to close down in two years.
(A) likely
(B) probable
(C) possible
(D) maybe
疑问： 正解为(A) likely
校内解释如下:
1) likely 用于下列固定句构：
It is likely that + S + V　　......很可能......
= sb /sth is likely to V
2) possible 用于下列句构：
It is possible that + S + V　　......可能......
= It is possible for sb / sth to V
3) probable 用于下列句构中：
It is probable that + S + V　　......很可能......
在原文书看过 "It is possible to ..."的用法
