想要某个东西时，用 would like，这是一种礼貌的说法。（I'd like = I would like。）
I'd like 一个东西
I'd like a coffee, please.
She'd like two tickets.
We'd like a table for four.
试一试: ___ a coffee, please. (I'd like / I'd like to / I would to like) 答案: I'd like — 咖啡是个东西，所以 I'd like 后面直接接东西就行。只有动作前面才加 to，东西前面不用。
I'd like 做某事
想做某个动作时，在动词原形前用 would like to。别忘了加 to。
I'd like to order now.
She'd like to speak to you.
They'd like to book a room.
Not "I'd like order now." — say "I'd like to order now.". 动作前面一定要有 to：I'd like to order。
试一试: ___ now. (I'd like to order / I'd like order / I'd to like order) 答案: I'd like to order — "Order" 是个动作，所以前面要加 to：I'd like to order。而且 to 永远不会插在 would 和 like 中间。
试一试: ___ book a room for two nights. (I'd like to / I'd like / I'd to like) 答案: I'd like to — "Book" 是个动作，所以要加 to：I'd like to book。只有东西前面才用 I'd like（不加 to）。
提议：Would you like...?
想礼貌地问别人要不要什么，就把 would 放最前面：Would you like...?
Would you like a coffee?
Would you like to sit down?
What would you like?
试一试: ___ a coffee? (Would you like / You would like / Do you would like) 答案: Would you like — 问别人要不要的时候，would 放在最前面：Would you like a coffee? would 前面不用加 "do"。
I wouldn't like = I would not like
表示不想要某样东西，用 wouldn't like。（wouldn't = would not。）
I wouldn't like a cold coffee.
She wouldn't like a noisy room.
I would not like cold soup. = I wouldn't like cold soup.
试一试: ___ a table near the door. (I wouldn't like / I don't would like / I wouldn't like to) 答案: I wouldn't like — 桌子是个东西，所以 I wouldn't like 后面直接接东西，不加 to。（wouldn't = would not。）
试一试: ___ a cup of tea. (I'd like / Would I like / I'd like to) 答案: I'd like — 一杯茶是你想要的东西，所以 I'd like 后面直接接东西。（"Would I like" 是在提问；to 只用在动作前面。）
