do和does都是助动词.do用于第一\二人称单数,以及"我们\你们\他(她\它)们",does则用于第三人称单数.
例:"Do you like the dog?"
"She doesn't like the cat.
当用于一般疑问句时,句首要加do\does,此时动词要变回原形,具体依人称数而定.

肯定形式:She likes the cat.
like是一个使用频率较高的词，它既可作动词，又能作介词，弄不清楚的同学经常混淆用法。下面就已经学过的用法归纳如下：
一、作及物动词，意为“喜欢”，后接名词或代词，表示对某一事物的兴趣或爱好。例如： I like fish and vegetables very much. Jack doesn't like his work.
二、常与would,should连用，表示“想要、愿意、希望”，语气较为客气委婉。例如： Would you like something to drink?你想要喝点什么吗? I would like a bottle of orange and two cakes, please.我想要一瓶桔子汁和两块蛋糕。 三、like后接动词不定式作宾语，表示喜欢某项特定的或具体的活动。例如： Do you like to play basketball? No. I like to paly table tennis. His mother doesn't like to see a film.
四、like后也可跟动词的ing形式作宾语，强调喜欢和爱好的是一般性的行为或事实。例如： Do they like playing games? No. They like watching TV. The girl doesn't like doing housework.
五、How do you like…?句型主要用以询问对方对某个地方或某件事物等的看法，意为“你觉得…怎么样?”例如：
How do you like the city?你觉得这座城市怎么样? How do you like the film?你认为这部电影怎样?
How do you like…?和What do you think of …?意义相近，它们在口语中常用How about …?或What about…?代替。还要注意别和What do you like…?相混，该句型主要用以询问对方的兴趣爱好，意为“你喜欢什么?”例如：What do you like? I like swimming.
六、like作介词，意为“像”、“和……一样”。例如： She looks like her mother.
The boy jumps like a m＆＃111nkey.
It looks like rain.
We don't need a man like him
