I usually have some bread and milk. Sometimes I havesome eggs and beans. Which would you like with your meal, rice or noodles? Noodles, please! Would you like juice or coffee? No, thanks. I’d like a cup of tea. 3a Countable nouns： Uncountable nouns： eggs, beans, noodles bread, milk, rice, juice, coffee, tea would like 表达什么意思？可以缩写吗？ would like 意为“愿意；喜欢”，与want意义相近，但比want语气更委婉、 更正式。would like可与任何人称连用，没有人称和数的变化；与人称代词连用时，would可缩写为“’d”。 ①would like sth. “喜欢/想要某物” I’d like a large bowl of noodles. ②would like to do sth.“想要做某事” I would like to go to the park on weekends. ③would like sb.
