假如在一个系表结构中出现一个副词修饰语，怎么分辨这个副词是修饰什么词呢？是修饰系动词还是修饰其后的表语？譬如：
He is always late for school.
He is always at home at the weekend.
He is always a kind person.
He is always here when the weather is fine.
假如换其他的副词呢？譬如：He is very much like his mother.等。
告诉你一个检验的办法。假如always是修饰表语的，那它就与作表语的形容词和名词关系密切，不可以分开。假如它是中位状语，则要放在操作词之后，实意动词之前。我把你的句子稍作改动，改为其它时态，看看always的地方是不是有变化。
He has been always late for school for a year.
He has always been late for school for a year.
He has been always at home for a month.
He has always been at home for a month.
He will be always a kind person
He will always be a kind person.
He has been always here for 3 weeks.
He has always been here for 3 months.
He will be very much like his mother.
He will very much be like his mother.
我想目前你一个人都能做出判断了吧。
