问题补充：

I witnessed the gate of the bank open and many men entering it, but I couldn’t make them out in the darkness.

A. force

B. be forced

C. forcing

D. being forced

答案：

A. force

B. be forced

C. forcing

(答案→)D. being forced

解析：句意：我目击了银行大门被强制打开，许多人冲了进去，但是里面太黑我没能认出他们来。故being forced表示正在被冲开和and后面的内容是并列关系。所以选D。
