问题描述：

___ by a crowd of people,he felt nervous,____ what to say
a.Having been watched; not known
b.Being watched; not knowing
为什么选B?语法如何分析?尤其是第一个空

答

Being watched 表示当时是正在被人看着所以紧张
Having been watch 是现在完成时选起来有点牵强
第二个空因为前面he而且句子中的谓语已经有了所以属于主动用动词的ing形式

答

现在完成进行时表示从过去某一时间开始一直延续到现在的动作.现在这个动作可能刚刚终止,也可能仍在进行.
两个分句的动作是同事的没有先后所以没必要用现在完成进行时
强调的是被人看的状态
