定语从句中，如果关系代词在从句中作动词的宾语，关系代词可以省略。如果作介词的宾语，则不可省略。

speak to 后面接的应该是动宾还是介宾？The cartoonist we spoke to still uses pen and paper to make his drawings？这句话对吗那么后面这句话中 问题补充：1.speak to 后面如果接宾语的话，是动词的宾语还是介词的宾语？

这句话对
完整形式是The cartoonist （whom/who/that/省略）we spoke to still uses pen and paper to make his drawings.
（whom/who/that/省略）就是指代The cartoonist 在定语从句中作介词to的宾语。

对的

在定语从句中，关系代词that ,which, whom 在定语从句中作宾语宾语时可以省略，例如 he found the book ( which/that ) he lost yesterday. this is the boy (whom ) i talked of the other day. 如果定语从句中出现把从句中的介词提前到关系代词which和whom 之前，这时候关系代词which和whom 作介词宾语时，关系代词不能省,介词提前关系词不能用that . this is the pen ( which /that) he wrote his composition with. 在这个句子中which/that可省。 this is the pen with which he wrote his composition.这个句子中 which 就不能省。 i like the boy (whom ) we played football with. i like the boy with whom we played football .
