2019小學(xué)英語語法專題:介詞

  1、介詞是一種虛詞。不能單獨(dú)作句子成分,它只有跟它后面的賓語一起構(gòu)成介詞短語,才能在句子中起作用。

  有:in, on, under, with, behind, about, near, before, after, for, to, up, down, from, in front of, out of, fromto, at the back of

  2、表示時間的介詞有:at, on, in。

  (1)at表示在某一個具體的時間點(diǎn)上,或用在固定詞組中。如:at ten oclock, at 9:30 a.m., at night, at the weekend

  (2)on表示在某日或某日的時間段。如:on Friday, on the first of October, on Monday morning

  (3)in表示在某一段時間(月份、季節(jié))里。如:in the afternoon, in September, in summer, in 2005

  3、in一詞還有其他的固定搭配,如:in blue(穿著藍(lán)色的衣服),in English(用英語表達(dá)),take part in(參加)。
