一道英语题.

Question

my mother is a doctor and she also ____me to be a doctor
a.hopes b.promise c.wants d agrees

答案是C.
那A为什么不可以?告诉我区别.

Answer 1

选C

从语言环境来看 显然这句话意思是说我妈妈是个医生 他（希望）我也当个医生 所以 B D显然不合适
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)
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.

Answer 2

want sb. to do sth.
hope sb. do sth.
