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
