The real answer is depends on what you mean by like. If you are describing the feeling of like, then you can say, "喜欢“ but only if you can control the situation. If you would like your boyfriend to change his behavior, then use 希望. If you would like to go to the movies, then 想，想要， 要（more harsh). If you mean, like as if one thing is similiar to another, than 像这样 or 和…一样, to seem like is 好像... I could go on but the use of the word like depends on your context in english and you want to use it.

Usually people use "xi huan" in most situations.But if you like something best people use "ai si le"(爱死了）.

Exactly!They are all the same word:喜 欢

yes

对的，都可以用喜欢。
