一日一词【64】decide

decide

decide是个比较复杂的单词。它的难点在于与介词的搭配。一般来说，decide之后可以接三个不同的介词以表示不同的意思。

1．如果就某事作出决定，但至今尚未作出，可用about:
　We still have to decide about a date for our picnic.
我们仍须决定野餐的日期。

2．如已作出决定，则可在日期或该事之前加on或upon:
We have decided on June 8 as the date of the term examination.
　我们已决定6月8日为期终考试的日期。

3．如果表示反对做某事，可在decide后用against:
His wife decided against subscribing to the journal.
　他的太太决定不订阅那本杂志。

当然，如将decide作及物动词用，那么在它之后可跟动词不定式及其它相当于名词的结构。例如：

I decided to buy a new car.

They couldn’t decide where to go during the vacation.
