类型四:if 介词短语
这类结构往往要根据具体的语境来理解,但有些经常搭配的惯用结构也值得注意,如if in doubt, if at all, if by any chance等。如:
If in doubt, ask your doctor. He can give you further information. 你若有疑问,可以问问医生. 他会向你作进一步的说明。
Their policies have changed little, if at all, since the last election. 自上次选举以来,他们的政策就算是有所变化,也变得很少。
If by any chance you can’t manage dinner tonight, perhaps we can at least have a drink together. 就算你今晚不吃晚饭,也许我们至少可以一起喝一杯。
类型五:if ever
if ever 可视为习语,它通常与seldom连用,表示“极少”“难得”。如:
She seldom, if ever, goes to the cinema. 她难得看电影。
He seldom if ever travels abroad. 他到国外旅行,即使有过,也是极少的。
注:有时ever后面还修饰有其他词语。如:
The island is seldom if ever visited by ships. 这个岛难得有船停靠。
