What caused the accident and who was responsible for it ( )a mystery to us.
A.remains B.has been remained C.remain D.have been remained
A.remains B.has been remained C.remain D.have been remained
be responsible for sth. :负责
选D,意为:“谁造成的车祸和谁对这场车祸负责,已经对我们来说成了迷。”
选A. remain是系动词,不用于被动语态.
另外,()后的"a" mystery 也是个提示.
remain 后可加名词或名词词组,也可加形容词
be responsible for sth. 为...负责
译为”是什么引起了这场事故,由谁来为此事负责对我们来说仍然是个谜.”
A,前面是一个名词,后面还有个a mystery,是不是单数的意思啊!所以我选A
是选C么
D
