首先看一下hope, wish和want的用法
1.hope作“希望”解,主要用来表示主观上的愿望并对其实现抱有信心。可接
不定式(短语)或that引导的
从句,但不可接“宾语+不定式”,即
宾语补足语的结构,也称不定式的复合结构,例如:
We are hoping to see the president who will
come to China.
I hope that you can tell us the truth.
We hope you to meet us at the station. (错误)
2.wish作“但愿、希望”解,表示某种未完成或不能完成的愿望。可接不定式(短语)、
双宾语、宾语+不定式的复合结构以及that从句,例如:
I wish you to go to Beijing with me next year.
Everyone wish (that) he could pass the English exam.
We wish you success/ (to be) happy.
I wish (that) I were a millionaire.
注意:表示实现愿望的可能性不大或根本不可能时,从句用
虚拟语气。
3.want作“想要”解,可接名词、不定式短语、还可接宾语+不定式/
现在分词/过去分词的复合结构,例如:A
Mr. Black wants to see you, sir.
I don’t want you to make so much trouble.
He wanted his hair cut after work.
I want you telling stories all the time.
但当want作“需要”解时,则后接V-ing的形式(表示被动的含义)或不定式的复合结构,此时用法跟need相似,例如:
The floor wants cleaning/to be cleaned.
回到原题:
如果用hope me to be,意思ok,但语法上不正确,因为hope不可接宾语+不定式,而wish通常用于纯粹的美好愿望表达,但实现希望不大,很显然父母是真心希望孩子成为doctor,所以不能用wish,故选want.
