二、用 “Would you like...?” 征求对方意见
1. 含义
“Would you like...?”用于询问对方是否愿意做某事或是否想要某物,意为“你愿意⋯吗?/你想要吗?”。
· “Would you like”后面既可以加名词、名词短语
· “Would you like”又可以加不定式“to do sth.”。意为 “想要去做某事”
如: Would you like an ice cream?
= Would you like to have an ice cream? 你想吃个冰淇淋吗?
2. 回答
对“Would you like...?”进行回答时
· 肯定回答为“Yes, please.”,意为“好的, 太感谢了。”
· 否定回答为“ No, thanks/thank you.”, 意为“不了, 谢谢。”
如:—Would you like a new T-shirt? 你想要一件新T恤衫吗?
—Yes, please. 好的,太感谢了。/No,thanks. 不了,谢谢。
3. would like 与 want
would like中的would是情态动词。可将would like 看作一个整体,此时它的用法与want 类似。
询问对方是否想要某物时,还可以用“Do you want...?”。
如: Would you like a cake?
= Do you want a cake? 你想要一个蛋糕吗?
