it is convenient to you是否能够与it is convenient for you通用

对于人可以通用.it is convenient for/to sb.但是在下面句型中介词只能用for. it is convenient (+for sb.) to do sth.(对某人来说做...方便)
记住两个复合结构的不定式:for/of sb. to do sth.(仅此两种)
for本身无意义,其后的名词或代词是不定式的逻辑主语,这种结构的不定式可在句子中作主语,宾语,表语,定语和状语.(eg.)
it is very important for us to learn english well.
i don't think it impossible for him to be absent without leave.
this is for you to decide.
there are a lot of difficulties for them to overcome.
i stepped aside for her to pass.
后者这种复合结构(of sb.)只在句中作状语,句子的谓语一定是形容词,而且这形容词是表示不定式逻辑主语的性质或特征.
it is very foolish of you to believehim.=
you are very foolish because you believe him.
