Question

________ of danger in the street at night, she had to go home, with a friend ________ her.

[　　]

A．Warned; followed

B．Warning; following

C．Having warned; following

D．Having been warned; following

Answer 1

答案：
解析：

第一空考查非谓语动词．因先受到别人警告，才让朋友跟着她一起回家。 受警告的动作先于谓语动词的动作，且表被动，故用“现在分词完成被动”形式。B．C两项第一空投用被动，故排除；A项第一空用“warned”不能把动作先后顺序表达出来，且第二空若用“followed”后应有“by”，而此题没有，故用with＋宾语＋现在分词（表主动）独立主格结构。
