问题补充：

She often shares her deepest thoughts and fears with friends through QQ, as if they chatting in her living room.

A. were

B. are

C. had been

D. has been

答案：

(答案→)A. were

B. are

C. had been

D. has been

解析：答案：A考查虚拟语气。句意为：她经常在QQ上和朋友们分享她内心最深处的想法和担心，好像他们正在客厅里聊天似的。根据语境可知，as if引导的状语从句是与现在事实相反的虚拟语气，因此，从句中用be的过去式were。故答案选A。
