1、want想，想要，及物動詞 want sth想要某物（名詞或代詞作want的賓語）。 例：I want some tomatoes. want to do sth想做某事（動詞不定式作want的賓語）。.例：He wants to see a film. want sb to do sth想讓某人做某事（動詞不定式做賓語sb的補定語）。例：Ted"s father wants him to have two cakes.
2、would為情態動詞，沒有人稱和時態的變化。 would like sth想要某物。例：I would like some tomatoes. would like to do sth想做某事（動詞不定式做would，like的賓語）。例：I would like to see a film. would like sb to do sth想讓某人做某事（動詞不定式做賓語sb的補足語）。例：Ted"s father would like him to see a film. 由以上解析可以看出want=would like，只是would like的語氣比want顯得委婉，更適合服務場所。
3、但在問句中，他們的表現形式卻是迥異的。 例如在疑問句的結構上： Do you want some tomatoes?（助動詞do引導） Would you like some tomatoes?（情態動詞would提前） Does he want some tomatoes?（有人稱和時態的變化） Would you like some tomatoes?（沒有人稱和時態的變化） What do you want? What would you like?
