they always have a family meeting before ----.
a make decision b make a decision c making a decision d making decision
选哪个?为什么?before 的用法.

选C
before 是连词后面要跟动词ing形式,所以排除AB
decision是可数名词,所以说a decision或decisions
这样就只有C对了.
2.before除译为“在……之前”外,还可译为“还未……就……”；
“不到……就……”；“……才……”；“趁着还没……就……”；
“还没来得及……就……”等.
Please write it down before you forget it.
趁你现在没忘把它记下来.
Before I could get in a word,he had measured me.
我还没来得及插话他就给我量好了尺寸.
3.辨析before和since
before可构成句型：“it will(not)be...before...”和“it
was(not)...before...”,意为“多久之后才……”.
It won’t be long before we meet again.
It was some time before I realized the importance of it.
since可构成句型：“It is/has been...since...”,意为“做某事已有多
久了；已有多久没做某事了.”
It is three years since I smoked a cigar.
我不吸烟有三年了.
It is three years since I began to smoke.
我吸烟有三年了.
