在托福考试写作和口语中，很多同学们往往会分不清楚to和for两个介词之间的用法。今天A加未来小编为大家提供一次比较详细的指导，来帮助同学们更准备的进行这两个词的运用，一起来了解一下吧！
托福考试写作
TO
1.direction/destination/distance
从一个地方去另一个地方(movement)。这里要注意的是，movement不只是具体的place，也可以是比较抽象的地方。
Do you usually take the bus to school?/If you’re feeling sick you should talk to a doctor./It’s only 6 kilometers from my house to the office.
2.time/time between two points
表述截止到的时间点，或是从某个时间点到另一个时间点。
I study English Monday to Thursday every week./The supermarket is open from 9 to 7.
3.preference
表达两者之间更喜欢/倾向于选择某一个的时候。
I prefer chocolate ice cream to vanilla ice cream.
4.limit/endpoint
表达结束点或是极限点，常与up to换用。
During the flood,the water came to my knees./The tickets could cost up to$200 each during the high season.
For
1.benefits
表达益处/好处。
Ginger is great for your immune system.
2.duration/period of time
表达一段时间，因此常与完成时连用。
They’ve been living in the city for three years already./I’ve been waiting for 20 minutes already.Where are you?
3.helping someone
表达帮助谁，或为谁做什么事情。
I baked a cake for you./I need to collect the mail for my mother./Could you grab those apples for me?
4.function/use/purpose
表达功能以及用途，常用for+Ving。
Yeast is used for baking bread./That camera is used for taking pictures underwater.
TO&FOR
(reasons/motive)
两个介词都可以用来表达原因或是动机，只是在用法上略有不同，to后加动词原形，for后加名词。
He studied English to apply for a job./She is studying French for work.
Attention:
有时候这两个动词用在同一个句子中会出现完全不同的意思哦~be careful
My assistant brought lunch to me.
(这句话中“我”是destination，我的助理实际意义上把午餐带到了我这里)
My boss brought lunch for me.
(这句话在我的上司帮我带午餐过来，强调“帮我”)
类似的，大家来区别一下下面这两句吧：

(我打电话给妈妈)
I made a quick phone call for my mom.
(我帮妈妈打电话)
