有一道英语单选题We will have the final examinations next week,so our teachers are busy ____the exams.A.preparing forB.preparing为什么答案选B 不选A 呢?preparing 也是为考试准备呀
看了你这道题和begin的题,这么说你们也做百思喽?
prepare后面加东西,是准备了某些东西,prepare for是为某事而准备
此处意为老师出试卷（或者准备考试的东西,反正差不多就这个意思）,是准备了某些东西,无论是布置考场还是弄试卷还是什么.而学生们是备考,是为考试而准备（但不是准备东西!只是复习什么的,是准备事情!……）所以要用for.
还有一个微小的差别,prepare是乐意且有能力的,而for没有这个意思
看这个句子,这是网上找到的我认为很不错的句子,不过你大概也看过了
I prepared for the picnic by preparing some sandwiches.前者是准备野餐这件事,后者是准备三明治这个东西.
我是冒着采纳率降低的危险回答的…………没懂的话你可以再等等别人的回答,但一定采纳我啊…………祝你百思愉快!（话说初高中都做百思还是挺亲切的~）
那个……如果你问题补充里的意思是老师也要备考……我就不知道怎么解释了……这不是这道题的意思哒~
鸭子爱好者敬上

全部展开

但看这句our teachers are busy ____the exams.A、B带进去，都正确，但意思不同，前面是我们要考试，所以选B
补充：
prepare "准备什么事情" She is preparing the food.(她在准备食物)
prepare for "为什么事情做准备" She is preparing for their supper.(她在为他们的晚餐作准备)
"perpare"后的"the food"就是准备做的东西
"perpare for"后的"their supper"不是准备的直接作用的东西,她为晚餐做准备,可能是买菜,洗菜,炒菜...做这些的一切是为了"supper". 所以要加for
所以，第一个prepare for ，第二个prepare

收起

如果是A的话，变成老师在准备考试，显然不对

选B 的话意思就是为参加考试而准备了。
