Now, this is a separable phrasal verb, which means it can 'filter something out' or you can 'filter out something', and it basically means to remove something completely or to purify.
现在,这是一个可分动词语,意思是指“过滤掉一些东西”它可以用“filter something out”,也可以可以用“filter out something”,它基本意思是完全去除某物或净化某物。
Well, that's because this is a transitive phrasal verb and it's also separable so that gives us a little bit of flexibility when it comes to forming our sentence.
Right, it doesn't make any sense in English but the phrasal verb take off as in take off my hat is separable which means we can separate the elements within the phrasal verb.
这在英语中没有任何意义,但是语动词 take off 就像在摘下我帽子中一样是可分,这意味着我们可以分语动词中元素。
Now in addition to knowing if a phrasal verb is transitive or intransitive, you also need to know if it's separable or inseparable and this is as simple as it sounds!
