(定语)The girl will be back
2、 in two hours. (状语)Our English teacher is from Australia. (表语)Help yourself to some fish. (宾语补足语)1. 常用介词的用法辨析1， 表示时间的介词(1) at, on, in1 表示时间“点”用at.例如：The meeting began at half past seven. 会议七点半开始。 有时表示不确定的时间和短假期日的名词之前也可用at.例如： Most people were hungry at that time. 那时候大部分人都在挨饿。 Some people in cities h
3、ave a trip in the countryside at weekends.周末，城里的一些人到乡下旅游。2 表示时间“段”用on 或 in.一般说来，“在某一天”用on;指长于一天的时间段（年，月等）用in. 例如：The woman often does some washing on Saturdays. 那个女人常在星期六洗衣服。The farmers are very busy in autumn. 农民在秋季特别忙。3 表示某天的 morning, afternoon, evening 时用 on. 如果在 morning, afternoon, evening 之前有形容
4、词也用on. 例如：It happened on the morning of May 31st,2006.(2) during, for, since1 during 连接表示某一段特定时间的词。例如：what are you going to do during the summer holiday? 暑假你打算干什么？He was quite free during the week. 那一周他很清闲。2 for 连接表示不特定的一段时间的词。例如：Ive already waited for you for forty minutes. 我已经等了你40分钟了。3 since 后面接时
5、间的起点，其终点往往是现在，常与完成时连用。例如：she has been in hospital since last Wednesday. 从上周三起她就住院了。 （3）after, in 这两个介词都表示时间，意为“在什么之后”。他们的区别是：after 以过去为起点，表示过去的一段时间之后，通常用于过去时态；in 以现在为起点，表示将来的一段时间之后，通常用于将来时态。例如： The girl finished the work after three hours. 三个小时后，那个姑娘完成了工作。 I will return the book to you in two days.两
6、天后我把书还给你。 (4) since, after由since和after 引导的词组都可表示从过去某一点开始的时段，但since词组表示的时段一直延续到说话的时刻，因而往往要与现在完成时连用。而after词组所表示的时段纯系过去，因而要与一般过去时连用。例如：I havent heard from him since last summer.After five days the boy came back. （5）till/untill 表示“ 直到 为止”的意思。用于肯定句表示“一直做某事到某时”； 用于否定句表示“直到某时才做某事”。两者用法基本一样，可以相互替代。放在句首一般用un
7、till. 例如： He did his homework till midnight. 他做家庭作业一直到午夜。 He didnt do his homework till midnight. 他一直到午夜才做家庭作业。2.表示地点，位置的介词（1） in, on, to ,at 这四个介词都表示地理位置的关系。1 in 表示在某一范围内。例如：They are all in the classroom. 他们全在教室里。2 on 表示在某个物体上或表示两个不同的个体相邻或接壤。例如：Your clothes are on the floor. 你的衣服在地板上。America stands
8、 on Canada. 美国和加拿大接壤。3 to 表示两个个体之间有一段距离或隔海相望。例如：Yantai lies to Dalian. 烟台和大连相对。They are standing face to face, being silent. 他们面对面站着，沉默不语。4 at 表示在小而狭窄的场合或街道的门牌号数。例如：A car stopped at the school gate. We found him at 56 Xinjian Road.（2） above, over, on 都表示一个物体高于另一个物体，可翻译为“在。上面”。1 on 指两个物体表面接触，一个在另一个的上
9、面.例如：Dont put your feet on the chair.2 above 表示位置高于某物，在其上方，但不是正上方，它的反义词是 below.例如：A bird is flying above the tree. 一只鸟在树的上方飞翔。 3 over 表示在正上方，指垂直方向，她的反义词是under.例如： They will build a bridge over the river. 他们要在河上修一座桥。（3） between ,among1 between 一般指两人或两物之间。例如：We have a farm between the hill and the riv
10、er. 我们在小山和河之间有一个农场。2 among 指三个或三个以上的人或物之间，其宾语是名词或代词。 例如：There is a thief among the passengers. 在乘客当中有一个小偷。（4） across , through1 across 指从一边到另一边，“横过或越过物体的表面”。例如：Be careful when youre walking across the street. 你过马路时要当心。2 through 意为“ 穿过或通过”空间。 例如：It is difficult for us to go through the thick forest.

13、问题。2， 表示“除去”的介词 except, besides, but(1) except 通常跟名词，代词，介词短语或从句，作“除了 以外不再有”或“不把 包括在内”讲，即在整体中除去一部分，有时用于all , none 等词的后面。例如：Everyone is here except Mr. King and his wife.除了金先生和他的妻子外，人都到齐了。The boy is afraid of nobody except his father.除了他父亲以外他谁都不怕。（2）but 多和nobody, nothing, who, no, one, one, everyone,
14、all 等连用，与 except意思相近，意为“ 除了 以外”，后面跟名词或代词。 例如： He hate all his subjects but P .
