A.have B.would have C.ought to have D.having
同志们呀,帮帮忙吧,急用!!

答案是:B
分析:这是个if引导的虚拟语气句,从句动词是:wanted,时态是过去式,故主句则用would/could done。再结合选项可知应选B。(虚拟语气很重要,要弄会)

选B
虚拟语气:从句用一般过去时,主句用情态动词+动词的过去分词,表示本应该做的事情却没做,或表示本该发生的事情却没发生,和现实/事实恰好相反。

B.
IF表示此句是虚拟语气。

it是先行词,主句是后面的that从句,倒过来你就清楚了,the boys have to finish the game quickly became obvious (to us)(omitted)if they wanted to avoid the storm。2个对应的时态是became 和wanted。主句用一般现在时就可以了
