单词hope，want，wish，expect有什么区别

　　不同点：
（1）wish +宾+ to +动词原形表示命令,hope无此用法
I wish you to go意思是我要你去
（2）hope后不能直接跟名词作宾语,可跟for +名词,表示可实现的“希望”,wish虽也跟for +名词,但表示难实现的“愿望”.
I hope for success .我希望成功.
I wish for a car .我很想得到小汽车
（3）hope和wish可跟that从句,但hope + that表示希望
wish + that表示“愿望”,且从句动词用虚拟语气
I hope you”ll be better soon .
I wish I were ten years younger .
(4)wish可跟双宾语
We wish you a happy New Year
wish 意思是对某一特定物的欲望、向往或强烈倾向
I wish you well. 我希望你健康.
Expect 意思是期待某事或某人可能的发生或出现：
You can expect us for lunch.
你可以等我们一起吃午饭.
Hope 意思是热切期望并对获得所期待之物的可能性方面有一定的信心：
I hope to see you soon.
我希望不久就见到你.
"Want" is often used when you have a strong desire for something or when you have a need for something. The goal is easy to be achieved.
For example, I want to have some Italian food tonight.
Another example, I want to learn French.
The word "Hope" is quite similar to the word "Expect". "Hope" is often used when you have a desire with expectation of obtainment, which means you expect that to happen.
For example, I hope (expect) you will keep your promises.
Another example, I hope (expect)the person I am going to live with is a vegetarian.
"Wish" is often used when you have a desire for something that is unattainable, which means the goal is impossible to fulfilled.
For example, I wish I can be as smart as Albert Einstein (In reality, I know I can never be as smart as Albert Einstein because my IQ is lower than his.)
Another example, I wish I am an astronaut (In reality, I know I can never become an astronaunt.)

　　wish 语气不如desire 强，且可以表示一种不能实现的愿望，(从句动词有虚拟语气形式);后接“不定式”或“代词/名词+不定式”结构。所表示的“希望”大体是可以实现的;此外，还可以接双宾语，表“祝愿”或表委婉的语气。
　　如： I wish I could fly to the moon in a spaceship one day. 但愿有一天我能坐宇宙飞船飞向月球。
　　want “想”其搭配关系为：want to do sth. Or want sb to do sth. 比较口语化，没有wish那样正式。
　　如：She wants me to do with her.
　　hope 表对愿望的实现抱有一定的信心。后接“不定式;that 从句。”但不能接 双宾语。
　　如：I hope to be a doctor. 我希望当一名医生。
　　expect “期待、盼望、预料”等，指对某一特定的事件的发生抱有颇大的信心。
　　如：We are expecting a letter from her. 我们当时正期待着她的来信。
