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.)
