介词 (2).ppt

1、介词:介词是一种虚词，它不能单独使用，后面要跟名词、人称代词宾格或动名词。同一个动词，搭配不同的介词，可以衍变出各种不同含义的词组来，而且在不同场合所用介词也各不相同。因此，介词的用法是比较复杂的，要求我们去逐个记住。只有在看懂、理解整个句意的前提下，才能选对正确的介词。1与形容词搭配的词组有：be afraid of（怕）be angry with（生某人的气）be away from（不在某地）be different from（与不同）be good at（善于）be good/bad for(对有益/有害)be interested in（对感兴趣）be late for（迟到）be/

2、get ready for（为作好准备）be sure of(对有把握)be worried about（为感到担忧）2介词后常用人称代词宾格和动词-ing形式 1)You must take good care of her.2)Thank you for teaching us so well.3几组易混淆的介词 A“在.之后”in+一段时间（用于一般将来时）after+一段时间（用于一般过去时）after+一点时间（常用于一般将来时）如：The baby stopped crying after half an hour.The baby will stop crying in half

3、 an hour.They will visit their teacher after Friday.B for+一段时间 since+过去的一点时间 (这两者常是现在完成时的标志.)C be made of 用制成 be made in“由某地制造”be made by somebody“由某人制成”D in,on,at表时间 in“在某月(季节、年)等”eg:in 1996,in January,in summer 还有固定词组：in the morning,in a week,in a minute,in time,in the end on 用于指具体的某一天或专指某一天上午、下午或

4、晚上等 On Christmas Day,on the night of February 16 at“用于具体时刻前和某些固定词组中”固定词组：at seven,at the moment,at night,at last,at first,at noon,at times,at once,at this time of the year,at the beginning of,at the end of this month,at the same time 注意：在表时间里，下列情况下一般不用介词。词组里有：next,last,this,that,tomorrow,yesterday,o

5、ne,every,all 以及the day before yesterday和the day after tomorrow 前不用介词。如:不能说 in tomorrow,只能说 tomorrow 在明天 E.except+宾格/doing something 除之外”（不包括本身）Everyone is at school today except Lin Tao.(同义句转换)=Only Lin Tao isnt at school today.F“用”通过交通工具 by plane 用语言 in English 通过媒介 on/over the telephone,on/over th

6、e radio,on TV 用工具手段 with a pen,with ones hands G between“在和（两者）之间”between.and.,between the two.在.之间(二者)among 在.之间(三者或三者以上)Sue spent over two hours _ her homework yesterday evening.A.on B.with C.at D.over 例题解析:()Mr.Brown flew to Washington _ the night before last.A)inB)on C)atD)/在表达某一天的具体时间时，应该用介词“on

7、”。但是本句是表达“在前天的夜里”，与“在前天”(the day before yesterday）相仿，前面不该用任何介词，所以本题答案应该选“D”。()The school gate is _ the north of the classroom building.A)in B)to C)on D)at 在英语中，表达“东、南、西、北”的方位介词常见有三个：表示在方位区域的内部时，用介词“in”。如：The playground is in the south of the school.（操场在学校的南面。）表示在与方位区域连壤的外部时，应该用介词“on”。如：Room 203 is o

8、n the west of Room 205.（203室在205室的西面。）表示在与方位区域不连壤的外部时，应该用介词“to”。如：Shanghai is to the east of Nanjing.（上海在南京的东面。）本题的“校门”在“教学大楼”的北面，应该用介词“to”，所以答案应该选“B”。()Youll get one thousand dollars _.A)after allB)at allC)in all D)all together “after all”意为“到底”、“毕竟”、“终于”；“at all”通常与“not”连用，意为“完全不”、“一点也不”；“in all”通

9、常用于数量词后面，意为“总共”，同义词是“altogether”。所以本题答案应该选“C”。()This bus can run _ 70 miles an hour.A)forB)withC)atD)in 在表示“速度”、“温度”、“价格”意思时，应该用介词“at”。所以本题答案应该选“C”。()Its said he stayed there quietly _ two oclock that afternoon.A)on B)atC)untilD)by “at two oclock that afternoon”意为“在昨天下午两点钟”，时态通常用“过去进行时”；“by two oclo

10、ck that afternoon”意为“在昨天下午两点钟前”，时态通常用“过去完成时”；“until two oclock that afternoon”意为“直到昨天下午两点钟”，时态通常用“一般过去时”。本句中“stay”是延续动词，因此可用“until”句型；如果句中谓语是瞬间动词的话，就应该用“not until”句型了。所以本题答案应该选“C”。()Tom didnt attend the lecture yesterday evening _ his illness.A)asB)for C)because D)because of 在本句中，“因为生病”是一个词语，而不是原因状语

11、从句，因此，不能选连词“as”、“for”或“because”来连接，而要用介词词组“because of”。所以本题答案应该选“D”。()Now its quite important _ us to make full use of time.A)forB)toC)ofD)with “Its important to sb.”（意为“它对某人来说很重要”）是词语搭配，“Its for sb.to do”（意为“做某事对某人来说是怎样的”）是句型。当两者交叉、重叠使用时，词语要让位于句型。所以本题答案应该选“A”。同样，“I like it so much that”句型中用“so”、而不用

12、“very”，也属于这种类型的表达方式。()Its nice _ you to get the ticket _ F1.Its said the car-race is very exciting.A)of,for B)for,forC)of,ofD)for,of 这句是“Its of sb.to do”句型，意为“某人真是怎么样，做了某事”。后半句中“ticket for”是固定词语，意为“什么内容的票子”。所以本题答案应该选“A”。习题训练:Choose the best answer ()1.You can draw it _ paints and brushes.A)byB)with
