The careless driver is ___ for the traffic accident ___ yest
The careless driver is ___ for the traffic accident ___ yesterday. A.to blame; happened B.to blame; happening C.to be blamed; happened D.to be blamed; happening 选B 我选A来着
选B呀! be to blame for词组,没什么好说的 == 首先,这句话有谓语动词了,后面又不是从句,所以非谓语一般用ing表主动,ed表被动.而happen是主动的,所以用B == 因为句子本应是The careless driver is ___ for the traffic accident (which happened) yesterday 定语从句.接着省略which,ing表主动
