一、would like 的主语可以是第三人称
例句：She would like a cup of tea.(主语是she，she是第三人称单数)
二、would like ，中文意思是：想要，没有人称、时态和数的变化，would like 后可以接名词、动词不定式。另外主语和would可以缩写成“主语'd”，例如：he would 可以缩写成he'd.
例如：He would like some water.(would like 后面接名词水，意为“想要水”)
例如：She would like to go out.(would like 后面接动词不定式“to go out”，意为“想要出去”）
三、"想要"除了用"would like "表达，还可以使用“want”，want后面可以接名词、动词不定式，但是“want”有人称、时态和数的变化。
例一：I want a bottle of water.(I是第一人称单数，want用动词原形，句意：我想要一瓶水)
例二：She wants a bottle of water.(she是三单，所以谓语动词want加s)
例三：He wanted a bottle yesterday.(时间状语yesterday提示句子的时态是一般过去时，所以want加ed变成动词过去式)
例五：I want to stay at home.(want 加动词不定式，意为“想要做某事”
would like主语可以是第三人称吗
可以。
“ would like ”意为“想要”，would是情态动词，没有人称和数的变化.当主语是第一人称时，would 可与 should 换用，它们都可以缩写为 'd ，并且 like 也可换成 love.
例如：He would like to go shopping
①，1 Would like to do sth. 想要做某事Would like sb. to do sth. 想要某人去做某事。
如： He would like to go out for a walk.?他想要出去散步。
Our parents would like us to study well.
②，后接名词或代词，表示具体"要"某样东西。
例：I would like a cup of coffee.我要两杯咖啡。
He would like a large bowl of noodles.
My mother would like an apple.
③后接动词不定式(就是to do形式)，表示意愿、喜爱，常用于有礼貌地提出邀请、请求或建议。
例：I would like to help you.我愿意帮你。
She'd like to eat swim.
3、would like sb. to do sth.想要某人做某事。
例：I'd like you to meet them.我想要你见他们。
I'd like him to do my homework.
④Would you like...?你(们)想要…吗?表示向对方提出客气的、有礼貌的请求、邀请、希望或询问等。
例：Would you like an apple?你想要个苹果吗?
它的肯定回答多用Yes， please./Yes， I'd (We'd) like (love) to./Certainly./Yes， thank you.等否定回答常用No， thanks./No， thank you.等。
例：-Would you like to drink some tea?你要喝茶吗?
