so that与such that用法区别

so.that和 such.that用法区别,so.that和such.that的意思均为“如此以致”，都用来引导结果状语从句。但二者用法不尽相同，现归纳如下： 1） so.that结构中的so为副词，后面跟形容词或副词； such.that中的such为形容词，后面接名词(名词前可以有形容词或副词修饰)。 例如： He became/is so angry that he couldnt speak. 他变得很生气，以致说不出话来。 It was such a fine day that we went out for a walk.,2) 当that前的名词有表示数量多少的many, much, few, little等修饰时，只能用so，不能用such. 例如： There was so much noise outside that we couldn't hear the teacher. He had so many falls that he was black and blue all over.,注意：若名词前的little解释为“小(的)”意思时，则仍用such, 而不能用so. 例如： It is such a little sheep that it cant run fast.它是一只小绵羊，它不能够跑得快。,3) 当that前是单数可数名词且该名词前面有形容词修饰时，so与such可以互换， 即：soadj.a/ann. sucha/anadj.n.。 例如： She is so good a teacher that we all love her. She is such a good teacher that we all love her.她是一位好老师，我们都爱她。,4) 当that前是不可数名词或复数可数名词时，则必须用such，不能用so来代替。 例如： It was such fine weather that they all went swimming. They are such nice apples that we would like to eat them.,( )1.It was_difficult a question that_people could answer it. A.so,few B.so,a few C.such,few D.such,a few,A,由此可知第一空应当使用so，故排除C和D；根据前一句子“问题如此难”可知“几乎没有人可以回答出来”，故正确答案为A项。a few表示肯定意义，意思为“一些”；few表示否定意义，意思是“很少，几乎没有”。,seem,seem可用作连系动词或不及物动词，意为“似乎，好像”，其常见的用法有：,一seem常常和不定式，形容词，分词，名词和介词短语搭配。如:,1seem+不定式（短语） I seemed to hear a voice in the distance 我好像听到那边有声音。 Your advice seems to be doing me a favor . 你的建议似乎帮了我个大忙。 I seem to have caught a cold . 我好像感冒了。,seem to be doing sth 表示不定式的动作和主句中seem是同一个时态， 比如，He seems to be doing his homework. 他好像正在做作业； seem to do 表示不定式的动作发生在主句动词seem之后， 比如It seems to rain. 好像要下雨了。 rain的动作，是发生在seem之后的； seem to have done sth 表示不定式的动作发生在主句动词seem之前， 比如 she seems to have finished her homework. 她好像做完了她的家庭作业。finish的动作发生在seem之前,注意：,1.seem后跟不定式（短语）时，要注意不定式所表示动作发生的时间，以此来确定不定式的时态。 不定式的一般式(to do)表示的动作或状态通常发生在谓语动作之后或同时发生 进行式(to be doing)表示其动作正在进行，与谓语动词发生的动作同时进行。 完成式(to have done)表示的动作或状态通常发生在谓语动作之前。,2.seem +形容词,a) She seems quite happy today. b) The enemy seems powerful but in fact it is weak. 注此句式可看作是seem +to be +adj.句式的一种简化形式。 如例a可转换为： She seems to be quite happy today. 例b可转换为： The enemy seems to be powerful but in fact it is weak. 但目前由于英语的发展，seem+to be+形容词结构的用法已越来越少，seem+adj的结构已趋成型，属口语语体。,3Seem+分词,a) The situation seemed quite encouraging. b) The news seems exciting. c) They seems interested in the film. 注seem后用现在分词还是过去分词取决于分词本身的逻辑主语，如句中的主语（盍作的执行者）是分词的逻辑主语，用现在分词，反之用过去分词。,4、seem+名词,a) She seems a clever girl. b) Her mother seems a teacher. c) It seemed a long time before my turn came.,5.seem+介词短语,They seemed in high spirits.,seem 常用句型,用于说明主语的特征或状态，表语多为名词或形容词，有时是其他的词或短语。 e.g. Tom seems (to be) a very clever boy. Tom似乎是一个聪明的孩子。 Mr. Black seemed (to be) quite happy. 布莱克先生好像十分快乐。,一、主语+seem + (to be) +表语,二、“主语+ seem + 不定式”,此句型中的seem与不定式一起构成复合谓语。 The young man seemed to have changed much. 这个年轻人看起来变化很大。 Mrs Green doesnt seem （或seems not ） to like the idea. 格林夫人似乎不太喜欢这个主意。,It seems +that 从句,It 是形式主语，that引导主语从句。 It seems that no one knows what has happened in the park. 似乎没有人知道在公园发生了什么事。 It seems to me that Mr Brown will not come again. 在我看来布朗先生不会再来了。,There seem to be+名词,to be可以省略，seem的单复数形式要根据后面作主和的名词的单复数形式而定。 There doesn't seem to be much hope of our beating that team. 我们队似乎不太可能打赢那支队。 There seems no need to wait longer. 看来没有再等的必要了。,
