为什么不能加关系代词

I can't think of anybody to invite.

x … whom to invite.

There are a lot of letters of invitation to send in the morning.

x ... which to send in the morning.

为什么句中用关系代词反而是错的,不用是对的了

下面为什么又可以加了

The children would have a garden in which to play.

= ... to play in.

He was miserable unless he has neighbours with whom to chat.

= ... unless he has neighbours to chat with.

带有关系代词的不定式作定语只有一种形式:介词+which/whom+to do。即关系代词必须在不定式短语中作介词的宾语,且介词+关系代词必须置于不定式之前。如果关系代词是不定式的宾语或者关系代词是介词的宾语但介词在不定式之后,则关系代词是必须省略而不能出现的。现在你自己体会上面四个句子中,为什么前二个不能加关系代词(关系代词是不定式的宾语是必须省略的),后两句介词在不定式之后就不能再用关系代词了。
