therefor可以用在句首吗？
therefore可以用在句首。
therefore一般不放句末。放在句首时，后面要用逗号；放在句中时，前后都要用逗号。
如果用therefor连接两个分句，其后用不用逗号无所谓。若第二个分句前是逗号或无符号，则要注意therefore是副词，要保持句子完整，应用and therefore。

therefore和for的区别？
therefor与therefore在意义上是不同的.therefor是个副词,作“为此”(for that,for this,for it)解,用于正式语体,尤其是法律文件中:
1.He will be paid therefor.他会为此得到报酬的.
2.My client did commit crime,but his motive therefor has not been established.(Crews)我的当事人确实犯了罪,但是他犯罪的动机尚未确定.
3.He promised to give a building for a hospital and the land necessary therefor.(WBD)他答应捐一个用作医院的建筑物以及为此所必需的土地.
therefore在词义上相当于thus,consequently,for that reason,as a result of that(因此,所以,结果).(and) therefore常用于连接两个并列的分句,therefore亦可用作从属连词的关联词:because...therefore,seeing(that)...therefore:
