介词
（preposition 简写prep.）
又称作前置词，表示名词、代词等与句中其他词的关系，在句中不能单独作句子成分。
介词后面一般有名词、代词或相当于名词的其他词类、短语或从句作它的宾语，表示与其他成分的关系。介词和它的宾语构成介词词组，在句中作状语，表语，补语，定语或介词宾语。介词可以分为时间介词、地点介词、方式介词、原因介词、数量介词和其他介词。
介词一般用于名词或者代词前面，表示该词与句中其他成分的关系。介词后面的名词或代词称为介词宾语（如果是人称代词，则要用宾格）。介词和介词宾语合在一起构成介词短语。
按构词成分
介词又称作前置词，表示它后面的名词或代词（或相当于名词的其他词类、短语或从句）与其他句子成分的关系。介词通常位于名词或代词之前。
（注意：介词是一种虚词，不能单独作句子成分，只能用在一个名词、代词或相当于名词的结构之前，可以与后面的词一起构成介词短语。）
简单介词
包括in，on，with，by，for，at，about，under，of等。
Where is the cat?
合成介词
包括into，within，throughout，inside，outside，without等
重叠介词

from behind 从...后面，
until after 直至...之后，
at about 在大约...，

短语介词
一个或两个简单介词和一个或几个其他词类构成一个短语，作用相当于一个介词，这就叫做短语介词。这类介词的末尾总是一个简单介词
如according to，because of，by means of，in addition to，in front of，in spite of，into等。
分词介词
有极少数介词的词尾是“-ing”，形似现在分词（其中也有些可做分词）。
常用的有：considering，regarding，respecting，including。
按词义分
表示“地点（包括动向）”的有：about around（在...附近、周围），above(高于、在...斜上方)，across(在...对面、横过)......

介词for用法归纳 用法1：(表目的)为了。如： They went out for a walk. 他们出去散步了。 What did you do that for? 你干吗这样做？ That’s what we’re here for. 这正是我们来的目的。 What’s she gone for this time? 她这次去干什么去了？ He was waiting for the bus. 他在等公共汽车。 【用法说明】在通常情况下，英语不用for doing sth 来表示目的。如： 他去那儿看他叔叔。 误：He went there for seeing his uncle. 正：He went there to see his uncle. 但是，若一个动名词已名词化，则可与for 连用表目的。如： He went there for swimming. 他去那儿游泳。(swimming 已名词化) 注意：若不是表目的，而是表原因、用途等，则其后可接动名词。(见下面的有关用法) 用法2：(表利益)为，为了。如： What can I do for you? 你想要我什么？ We study hard for our motherland. 我们为祖国努力学习。 Would you please carry this for me? 请你替我提这个东西好吗？ Do more exercise for the good of your health. 为了健康你要多运动。 【用法说明】(1) 有些后接双宾语的动词(如buy, choose, cook, fetch, find, get, order, prepare, sing, spare 等)，当双宾语易位时，通常用for 来引出间接宾语，表示间接宾语为受益者。如： She made her daughter a dress. / She made a dress for her daughter. 她为她女儿做了件连衣裙。 He cooked us some potatoes. / He cooked some potatoes for us. 他为我们煮了些土豆。 注意，类似下面这样的句子必须用for： He bought a new chair for the office. 他为办公室买了张新办公椅。 (2) 注意不要按汉语字面意思，在一些及物动词后误加介词for： 他们决定在电视上为他们的新产品打广告。 误：They decided to advertise for their new product on TV. 正：They decided to advertise their new product on TV. 注：advertise 可用作及物或不及物动词，但含义不同：advertise sth＝为卖出某物而打广告；advertise for sth＝为寻找某物而打广告。如：advertise for a job=登广告求职。由于受汉语“为”的影响，而此处误加了介词for。类似地，汉语中的“为人民服务”，说成英语是serve the people，而不是serve for the people，“为某人的死报仇”，说成英语是avenge sb’s death，而不是avenge for sb’s death，等等。用法3：(表用途)用于，用来。如： Knives are used for cutting things. 小刀是用来切东西的。 This knife is for cutting bread. 这把小刀是用于切面包的。 It’s a machine for slicing bread. 这是切面包的机器。 The doctor gave her some medicine for her cold. 医生给了她一些感冒药。 用法4：为得到，为拿到，为取得。如： He went home for his book. 他回家拿书。 He went to his friend for advice. 他去向朋友请教。 She often asked her parents for money. 她经常向父母要钱。
小学英语介词知识点（口诀） 必背1 年月周前要用in，日子前面却不行。遇到几号要用on，上午下午又是in。 要说某日上下午，用on换in才能行。午夜黄昏用at，黎明用它也不借。 at也在时分前，说“差”用to，说“过”要用part。 必背2 in在……里，out在……外，在旁边的是beside，靠近的为by 。 on在……上，under在……下，above在上头，below 在底下。 必背3 this、that、tomorrow，yesterday，next、last、one。 接年、月、季、星期、周，介词省略已习惯。 over、under正上下，above、below则不然，若与数量词连用，混合使用亦无关。 beyond超出、无、不能，against靠着，对与反。
besides，except分内外，among之内along沿。同类比较except，加for异类记心间。 必背4 before、after表一点，ago、later表一段。before能接完成时，ago过去极有限。 since以来during间，since时态多变换。 与之相比beside，除了last but one。 必背5 ①早、午、晚要用in in the morning 在早上 in the afternoon 在下午 in the evening在晚上 in the day 在白天 ②黎明、午、夜、点与分用at at night 在夜间 six o‘clock 在6点钟 at 7：30 在7点半 at nine fif** 在9点15分 at the weekend 在周末 ③年、月、年月、季节、周用in。例;

We study hard for our motherland. 我们为祖国努力学习。 Would you please carry this for me? 请你替我提这个东西好吗? Do more exercise for the good of your health. 为了健康你要多运动。 【用法说明】(1) 有些后接双宾语的动词(如buy, choose, cook, fetch, find, get, order, prepare, sing, spare 等)，当双宾语易位时，通常用for 来引出间接宾语，表示间接宾语为受益者。如：
