西沙群岛照片:表语和状语怎么区分？

表语是和系动词同时出现的，也就是说有系动词才有表语。比哪i feel good，因为feel是系动词，所以good是表语。
表示限定，程度，方式，比较，让步等意思是状语，在英语中时间和地点也叫做时间状语和地点状语。
i knew it by asking her.
i went to the market yesterday.中的by asking her和yesterday是状语，分别表示方式和时间。

A predicative (表语) word follows the verb, e.g. old in the dog is old (but not in the old dog) and house in there is a large house.

The adverbial adjunct (状语) directly modifies the verb in a manner similar to an adjective modifying a head noun. This boosts the force of the verb, heightening our sense of it from its usual norm. Splitting the infinitive creates a type of “going” that is different from other types (e.g., a slowly go, an easily go, a meekly go). The effect of this placement almost creates a “new” verb. Where we position the adjunct syntactically depends, or should depend, on the communicative effect we wish to convey.
