介词为虚词，不能单独充当句子成分，必须同名词、代词、短语、句子构成介词短语，才能充当句子成分。介词短语在句中常作表语、定语、状语和补足语。介词的用法比较复杂，在英语学习中须多多注意。 想看基础知识，请看介词。
下面我们来学点介词口诀。帮你快速记单词。
一、介词及介词短语
介词像个“游离体”， 名前动后常出现，
一旦组成“某结构”， 句中成分有一位。
“介+宾”叫“介短”， 作“形、副”句里边。
“宾补、表、定、状”， 都能用得上①。
“动+介”——动词性②， “及、不及物”谓语用。
成语、习语常固定， 应用起来有弹性。
注 ①介词后面的名词、代词或数词是介词的宾语，介词和介词宾语合成介词短语。介词短语在句中的语法作用相当于形容词或副词，在句中做宾（主）语、补足语、表语、定语或状语。
②“动词+介词（副词）”组成一个动词词组或短语动词，其语法作用相当于一个及物动词或不及物动词，在句中作谓语。
二、介词在句中的位置
介词活跃句关键， 短语合成形简单，
独作成分看不见， 介短表定状可担。
before时空在之前， after之后off远。
直上 over，above斜， under，below下相反。
直到till，on表面， 穿过through，for因缘。
by表旁边in里面， with伴随by车船。
时间地点at、in、on， 二者between多among，
behind后面beside旁， 附近near沿着along。
from来自like像， 表示目的for，to当。
of所属周围round， 向上up向下down。
三、on,at,in用法巧记
on，at，in这三个常用介词都可以表示时间和地点，但具体用法不同，多数学生对它们混淆不清。现在只要记住了口诀，就可避免at，on，in的种种误用。
1. on，in，at表示时间
on“在具体某一天”①
“当某时”，动名词， arrival，death前；
用in一般“上”“下”“晚”；
on用于天，in用于月、季、年③；
限定三时in要变。④
at是个时间点，
“工作”“时刻”与“圣诞”⑤。
at noon（night），in the day，
习惯用语记心间。
注：①on表示在具体某一天及具体某一天的上午、下午和晚上。
例 On Mother's Day, we should sned flowers to our mother. 母亲节，我们应该送花给我们的母亲。
On my arrival home，I found he had gone already．当我到家时，我发现他已经走了。
② 当early，late用于句首修饰介词短语时，尽管表示具体某一天的上午、下午、晚上，都要用in，泛指一般的上、下午，晚上也用in 。
例 Early in the morning of National Day，I got up to catch the first bus to the zoo． 国庆节一清早，我便起床去赶到动物园的第一班公共汽车。

④当 morning，afternoon，evening有前位定语或后置定语限定时，就不用in而用on。
例 on a hot (summer) noon 在一个炎热（夏天）的中午
on Monday Morning 在星期一上午
on the morning of March 8th在3月8日上午
⑤ 表示某时某刻及在work，Christmas前用at。
例 We get up at eight o’clock． 我们8点起床。

2. on，in，at表示地点
on“在之上”接触面，“靠近、接壤、左右边”①；
in“在里面”和“中间”②；
at表示小地点， “入口、车站、电影院”③；
home出现定语、冠， 须用in把at换④；
“夜间、车辆”若有限， 及“在途中”on在前⑤。
注： ①在表示地点时，指“在……之上（与表面接触）” “靠近、接壤”及“在左右边”都用on。
