        2.I should like to commend this dictionary to you
it's all have the meaning of "推荐" 
so i don't know what is the exaclt difference

Answer

Recommend: I will recommend you to my boss if you're interested in getting a job. I recommend the lasagne, it's very good.
Commend: I commend you on your excellent work. I commended the chef on such a great meal

Answer

I'll take your first example:

1.a  Can you recommend me a good lawyer? 
1.b  Can you commend me your good lawyer?

we "recommend" someone or something that goes with what is required, while we "commend" something or someone by delivering over to someone's care.  In other words, "recommend" is more of 'suggesting' and "commend" is of 'entrusting'.  therefore:

1.a  Can you recommend me a good lawyer? = Can you suggest a good lawyer?
1.b  Can you commend me your good lawyer? = Can you entrust me your good lawyer?
