第028句
If the letter to be mailed was placed on the writing table an hour ago, it is certain to be there now.
译文:如果那封要寄的信一个小时前是放在写字台上的,那它现在肯定还在那儿。
点睛:在if引导的条件状语从句中,to be mailed为letter的后置定语,表示将来的概念。该题考查不定式的用法,当certain在句中作表语,表示“一定会...”时,其后要跟动词不定式或that引导的从句。
He is certain to win the game.
他一定会赢得比赛。
He is certain that they will win the game.
他认定他们将赢得比赛。
考点归纳:将来时的表达方式:
*be going to do
It's going to rain。
要下雨了。
*be about to do
They’re about to leave.
他们就要走了。
*be to do
You are not to smoke in the office.
你不能在办公室里抽烟。
