我想要些茶。

一般有以下三种结构形式

② would like to do sth. 想要干某事

I would like to go with you. 我想和你一起去。

③ would like sb. to do sth. 想要某人干某事

※相关句型

（1）Would you like to do sth?“你愿意干某事吗？”这是日常生活中用来向对方有礼貌地提出建议或邀请的句型。

如果是同意，一般说Yes, I’d like/love to; 但是，如果是拒绝，我们也要说客气些，比如可以先说 “sorry”,再说明原因。 eg: -Would you like to play games? 你愿意做游戏吗？

-Yes, I’d love to. 是的，我愿意。

-Sorry, I have to do my homework. 对不起，我必须做作业。

（2）Let’s …一般可以用于提出建议，也可以用来表示邀请。如：

-Let’s stay at home and watch TV .我们在家里看电视吧。

-OK./ All right./ A good idea. 好。/ 好吧。/ 好主意。

（3）Would you like sth?意为“你想要某东西吗？”这也是日常生活中有礼貌地、语气很委婉地征求对方要求时的用语。

其肯定回答是:Yes, please./All right./Ok.等；

否定回答是:No, thanks.

eg: -Would you like some rice?你想要些米饭吗？

-Yes, please.请来一些。 -No, thanks.不，谢谢。
