请英语高手进,look like,looks like,looking 的正确用法,我一直认为looks like是用在第三人称单数的,可是课本上却出现第三人称单数也有Look like的,我就糊涂了,为什么说look the same而不能说looks the same

请英语高手进,
look like,looks like,looking 的正确用法,我一直认为looks like是用在第三人称单数的,可是课本上却出现第三人称单数也有Look like的,我就糊涂了,为什么说look the same而不能说looks the same 或者looking same,look 在动词时怎么用 名字时又怎么用
what does/do sb look like?
Their bags looks the same.这个句子中 Their bags不是复数吗？为什么还用looks?

一般现在时的第三人称单数只可能是Looks like.
楼主可否贴出原文来共同研究?
what does/do sb look like?
这是个疑问句,第三人称单数体现在前置的does,所以后面的look用原型.
Their bags looks the same.这里用looks是绝对错误的,应该是look the same.

因为这是个问句 do/does后要接动词原形的
