How long is it ____ the metting___?
A.When,began B.since,began C.when,begins D.since,has been begin 不是瞬间动词嘛 不是不能和how long连用的嘛?为什么不选D
答
问题在于since,从"the meeting" began的那一刻开始算起,选D的话就不能用since了,“How long has the meeting been on ?"
答
B
begin 是瞬间动词,但它不是作主句的谓语动词,而是从句的谓语动词,HOW LONG 可与SINCE 连用呀.SINCE后的时态要用一般过去时.
