北师大出版社 高一年级 下册 畅言教育Unit 6 DesignLesson 1 A Matter of Taste 教材分析本课是本单元的第一课。教材围绕三个著名的画家以及他们的作品展开。大部分学生对绘画不是很了解，所以需要对相关简单的知识进行介绍并引出话题词汇。本单元的Warm-up 部分做了很好的铺垫，学生在此基础上了解三位画家及其作品，并学会如何描述绘画作品。 本课的难点在于对话题词汇的积累，以及运用适当的词汇来描述绘画作品。因此在几个活动中分层次帮助学生识记并运用这些词汇。 教学目标Enable the Ss to have a good understanding of the basic usage of preposition. 教学重难点【教学重点】Help Ss grasp the usage of preposition of time, place and movement. 【教学难点】Use the target language to finish some exercises. 课前准备 A projector, some slides and a blackboard. 教学过程Step 1 PresentationPresent to students the definition and classification of preposition.介词(preposition)又叫做前置词，一般置于名词之前。它是一种虚词，一般不重读，在句中不单独作任何句子成分，只表示其后的名词或相当于名词的词语与其他句子成分的关系。介词和它的宾语构成介词词组，在句中作主语、状语、表语、补语或介词宾语。介词可以分为时间介词、地点介词、动作介词、方式介词、原因介词、数量介词和其他介词。Step 2 ExplanationT: Today well mainly deals with three kinds of prepositions: preposition of time, place and movement. Lets see one by one.Preposition of time1表示时间的介词有in，on和at。(1)表示某个世纪、年、月、季节、早上、下午、晚上用in。in 2007，in March，in springin the morning/afternoon/evening(2)表具体的某一天或某天的特定一段时间用on。on the 8th of March 2008，on the afternoon of 20th of May(3)在午间、夜间，在开头和结尾用at。at noon/night，at the beginning/end of2表示时间之前用before，之后用after或in。表示“在某段时间之后”，介词in短语常与将来时连用。after与表示“某段时间”的词语连用时，句子谓语动词常用过去时。after与表示“某一特定时间”的词语连用时，句子动词用过去时、将来时均可。e.g.Well have to finish the work before rain season.雨季到来之前，我们得干完这些活。Please wait here.Ill come back in a few minutes.请在这儿等一下。我几分钟后就回来。He came back from abroad after two years.两年后他从国外回来了。Well come back after five oclock.我们将在五点以后回来。3表延续的一段时间用for和since。for后只接表示一段时间的词语。而since只接表示特定时间点的词语。e.g. I have been here for two hours.我来这儿两小时了。I have worked here since 1996.自1996年以来，我一直在这儿工作。4by，during，till，until表时间。by表示时间点，表示“不迟于，到时候为止”。during可以表示一段持续的时间，也可以表示这段持续时间中的某一点或一刻，视具体情况而定。till与until也可以表示一段时间。一般来说，till在肯定句中与延续性动词连用，until则常用在否定句中，与瞬间动词连用。e.g.Your son will be all right by supper time.到晚饭时你儿子就会好了。He called on me during my absence.他来看我时我不在。He had stayed in Shanghai till last week.他在上海一直待到上星期。Dont go away until I come back.我回来你才能离开。Preposition of place1表示地点的in和at。介词in通常表示大地方，而at通常表示小地方。所谓的大地方或小地方是相对而言的。He arrived at New York in America two days ago.两天之前他到达了美国的纽约。2表示地点的at和to。at和to都可以表示“朝向”，但是at表示“以某一点为目标”，而to则单纯表示方向。Dont shout at me.别对我叫喊。This road leads to Paris.这条路通往巴黎。3.表示上下方位的词on 接触over/under 不接触，有锤子关系，正上方/ 正下方above/below 不接触，无垂直关系，仅仅高于或低于e.g.The moon was above the trees in the east.From the building ,we saw the lake below us .There was a big umbrella over my head and I felt cool under it .4. 常用来表示与某一点的关系： A 在B的范围内用in,在范围外用to,在接壤处用on e.g. Shanghai is in the east of China.
