湖南省临澧县第一中学高中英语论文高中英语常考点辨析 牛津版1. i was too tierd to eat anything we were given.【考点】副词too的用法【点拨】副词too用在tooto结构中，意为“太.以致不能”。【拓展】副词too是一个常用的词，表示“也，太”的意思。表示“也”时，通常用于肯定句。例如： its a nutritious meal and cheap too. 但在下列情况下可以用于否定句： 当too仅仅修饰某一个带有肯定意义的动词，或以否定的形式表示肯定意义的场合时。例如： wont you come ,too? 如果连用的两个句子都是否定句,并且第二个句子中被”也”强调的成分又位于句首时,”也”既可用too也可用either来表示，但它们在句中的位置不同。例如： tom didnt see the film ,and john too didntsee it. (比较：tom didnt see the film ,and john didnt see it , either.) 由too构成的常用结构有： tooto(太.以致于不.) 表示否定。例如:he was too tired to go any further .他太累了，再也走不动了。 在too前有not ,never 时，该结构不表示否定意义，通常表示“并不（太）.所以能.”之类的意思。例如：its never too late to mend .亡羊补牢未为晚矣。 在不定式前有not时，该结构表示肯定意义，通常表示“太（很、非常）.不会不.”之类的意思。例如：he is too careful not to notice it .他非常细心，不会不注意这一点。 当tooto跟少数形容词（如ready,glad,pleasd,willing,inclined,eager,easy,anxious等）搭配时，表示肯定意义。例如：he is too ready to help othors .他非常乐于助人。有时在该结构中，too前面会有only,but,all，其中的only,but,all相当于very。例如：we are but too willing to do it you.我们非常乐意为您效劳。 cannot(或can never)to表示“怎么.也不会过分”、“越.越好”的含义例如：one can never be too caerful in ones work.工作越细越好。you cannot praise the play too highly.这出戏对你无论怎么称赞都不过分。 “too+形容词+a(an)+名词”中too意为“太”。例如： its too hot a day for an outing .天太热，不能去郊游。 辨析： too much much too 在too much这个短语中，中心词是much，too在任何情况下都能修饰much，用来加强语气。该短语可根据much词性的不同在句中充当不同的成分。例如： i drank too much beer last night.(定语) you have given me too much.(宾语) he talks too much but does too little .(状语) too much has been said on how to learn english well.(主语) much too 只能作状语，修饰形容词或副词。例如： this one is much too big 2. he has been working much too hard at his lessons recently.special gloves are also worn so that people and objects in the film can be touched. 【考点】so that的用法 【点拨】句中的so that 为连词，意为“以便”，引导一个目的状语从句。 【拓展】so that 在句中可以引导目的状语从句，也可以引导结果状语从句。so that引导目的状语从句时，意为“以便，使能够”，从句中谓语由can,could,may,might,will,would,should等与实义动词够成。 lett try and arrange so that we can get there at one oclock.speak clearly so that they may understand you .i did this so that i might have a couple of weeks to prepare my essay.he wore a mask so that no one should recognize him.在非正式语体中，so that中的that 可以省略。例如： cant you fix it somehow so you could stay?illshow you so you can see how its done. 三者均可引导结果状语从句，但用法不尽相同。现分述如下（so that用法见上文 ）so.that 引导结果从句时，意思为“如此.以致.”，so是副词，后面接形容词或副词，有时so也单独使用。例如：he was so young that you must excuse him .they were all so sleepy (that)they could do nothing but yawn.当表示结果的部分为动词原形+.时，则用so+形容词、副词+as to 结构。例如：he got up so early as to catch the early bus .在such.that 中，such为形容词，后接名词。在非正式语体中，suchthat中的that 有时可省略。例如： it was such a hot day that everybody decided to stay home.the child had such a fever (that)he nearly died .也可以用suchas to+动词原形+.表示结果。例如：so i went about my job in such a way as to try to kill the two birds with one stone .此外,such还可以用作代词，such as to /such that 意思为“（是）这样（以致）”。例如：his bad behavior was such as to annoy everyone .the situation is such that agreement is unlikely.3.while we damage our environment ,we keep producing more people who need more land to live on and more food to eat!【考点】连词while的用法【点拨】句中while意为“当时候,与.同时”，引导时间状语从句。【拓展】作连词的while可以引导状语从句，表示时间、让步、对比、条件等语法意义。表示时间，意为“当.时候”。例如：they arrived while we were having dinner .在引导时间状语从句时，当从句中的主语与主句一致且从句的谓语中含有be动词时，从句的主语和be动词可省略。例如：he got hurt while (he was)playing football.表示让步，通常只置于句首，意为“尽管、虽然”，用来表示部分同意或接受某事。从句与主句常有互相交替，但强调的是交替后的主句。是比较：while she is a likeable girl ,she can be extremely difficult to work with.while she can be extremely difficult to work with ,she is a likeable girl.表示对比，相当于whereas,作“而，然而”解，用来强调两种情况、活动等之间的差别。例如：that region has plenty of natural resources whlie this one has none .表示条件，相当于so long as ，作“只要”解，例如：while there is life there is hope.注：在带有while引导的时间状语从句的主从复合句中，表示过去发生的事情时，主句和从句都可以同时用过去时或过去时，意思上没有多大差别。例如：i cooked the dinner while he played the piano .(=i was cooking the dinner while he was playing the piano)但如果两个动作持续的时间有长有短，持续时间长的用过去进行时，短的用过去时。由于while总是表示延续性的时间，因此在这种情况下，从句往往用进行时。例如： grandpa fell asleep while he was watching tv 辨析1：while though两者均有“虽然”之意，但while指前后两件事同时发生，居于平等地位，无主次之分，例如：while i like the color of this hat, i dont like its
