Question

those who are of great importance are_____ to make great achievements

those who are of great importance are_____ to make great achievements
A possibly B likely C probable D perhaps

Answer 1

答案：选B likely
因为：只有likely 才能用人做主语，即有sb be likely to do=it is likely to do 这种结构，
而possible ， probable 只能用形式主语it，即：it is possible/probable to do

请采纳，谢谢支持！

Answer 2

B
这几个选项中只有likely 是可以主语用人的，sb. is likely to do sth.
其他几个的主语是sth.

Answer 3

B，be likely to do / Be possible to do 主语不能是人 be likely to do 主语可以是人 也可以是物,而probable指某事很可能发生，perhaps就更不对了
