Question

请问下 I want 和I would（I would like）怎么区别? 能给点例句么

Answer 1

区别：
want=would like，只是would like的语气比want显得委婉，更适合服务场所。
1、want想，想要，及物动词。
want sth想要某物（名词或代词作want的宾语）。例：I want some tomatoes.
want to do sth想做某事（动词不定式作want的宾语）。例：He wants to see a film.
2、would为情态动词，没有人称和时态的变化。
would like sth想要某物。例：I would like some tomatoes.
would like to do sth想做某事（动词不定式做would,like的宾语）。例：I would like to see a film.
词义辨析
lack，want，absence，shortage，scarcity这些名词均含“缺乏，不足”之意。
lack普通用词，指部分或完全的不足。
want指完全或短缺某物，侧重缺少之物是必需的东西。使用范围比lack窄些。
absence指某物根本不存在或完全短缺，或某人虽存在，但未到现场。
shortage指不足，但侧重达不到规定的，需要的或已知应有的数量。
scarcity指产量不足或缺乏某物难以应付或满足需要

Answer 2

意思上差别不大.不同在于want 是行为动词,所以有时态和人称变化；would like 可以看成了情态动词,没有时态人称变化.比如：He wants to have a cake; He would like to have a cake.
