一、them前面加什么介詞
看意思決定呀。
in them
例如:You'll notice that a lot of different kinds medications do you have chlorine in them, you'll see that c l group.
你會注意到很多不同類型的藥物都含有氯,你會看到這類氯。
with them和他們
among them在他們中間
for them為他們
between them在他們之間
還有一些情況是不加的,比如 them作賓格的時候,賓語是動作的接受者。
例如:I beat them.我打了他們。
二、them they their 的用法
them是賓格,賓語是動作的接受者,比如I beat them.我打了他們,他們就是"打"的接受者
their是他們的
These are their books.
They是主格,比如They are Chinese.
介詞一般用在名詞代詞前面,表示方位,時間等,如on,in,at這些。
them(他她它們)是they的賓格,一般在介詞后 their(他它她們的)是they的形容詞性物主代詞,后面加名詞 they(他它她) 是代詞,作主語
三、介詞+which與介詞+them等怎么分別呀
介詞+which/whom 是定語從句,
介詞+them 是 普通的句子。
例如:
Last summer I happened to make friends with two American exchange students, from whom I learned much about America.
上面一個是定語從句,先行詞是students
Last summer I happened to make friends with two English students. From them I learned much about England.
這里是兩個獨立的句子,them指代前面一句話的students。
