英语翻译
She is good at English,isn't she?这句话中的at又是什么意思.
还有一个问题我想问一下是不是所有的情态动词后面都要接动词原形.
He must have drank a lot.You must not be late again.这两句话为什么后面的要加be动词,而前面的不用加,请大家祥细解说给我听
He must have drunk a lot.这句话我drunk这个词打错了，

good at ...,意思是擅长 ...She is good at English,isn't she?她英文是不是很不错?
He must have drunk a lot.must 后面跟动词完成时 have drunk,主谓结构
You must not be late again.must 后面跟系动词 be,表语是形容词 late,主系表结构
