英语语法分析

A phrasal verb refers to a verb combined with an adverb or a preposition, or sometimes both, to give a new meaning.

短语动词指的是动词与副词或介词，或者有时两者结合，赋予新的意义。

The phrasal verb 'tear up' is separable because you can say 'She tore the letter up' or 'She tore up the letter'.

* tear up 是可以分开的短语动词，因为既可以说 She tore the letter up ，又可以说 She tore up the letter。
