2、词，那么提升一下的话就可以想到它的如下同义词：话就可以想到它的如下同义词：significant, vital, significant, vital, main, key, crucial main, key, crucial 等。等。more examples:n方面方面 sideaspectsn表明表明 showdemonstrate, indicaten利用利用 useutilizen因此因此/结果结果sothereforen部分部分 partproportionn提高提高 improveenhancen改变改变 changetransformn强调强调/重视重视 emphasize

4、t-eventuallynbut-howevernif-provided thatn2 2、词汇准确性、词汇准确性nn 所谓词汇的准确性是指，我们在有一个词近而想到它的所谓词汇的准确性是指，我们在有一个词近而想到它的同义词之后，要结合语境选择恰当的用词同义词之后，要结合语境选择恰当的用词, ,并不是词汇等并不是词汇等级越高越好，必须还要考虑到适合于不同的语境。级越高越好，必须还要考虑到适合于不同的语境。n比如，眼睛大，这个比如，眼睛大，这个“大的大的”形容词，我们首先会想到形容词，我们首先会想到big,big,近而想到近而想到great, large, huge, vast, titanic,

5、 great, large, huge, vast, titanic, enormous etcenormous etc。那么是不是用后面的词就可以了呢？或者。那么是不是用后面的词就可以了呢？或者说用上说用上enormousenormous等词更能博得阅卷人的好感呢？答案是否等词更能博得阅卷人的好感呢？答案是否定的。在这里很明显用后面的词来修饰眼睛是不可以，只定的。在这里很明显用后面的词来修饰眼睛是不可以，只能用能用bigbig。二、造句二、造句1 1、词组、词组n很多考生平时写作不太擅长用词组，对于他们而言最很多考生平时写作不太擅长用词组，对于他们而言最习惯的就是想到汉语，然后对应汉语思维写

6、出英语句子，习惯的就是想到汉语，然后对应汉语思维写出英语句子，这种写作只能是单词的罗列组合，谈不上什么技巧文采可这种写作只能是单词的罗列组合，谈不上什么技巧文采可言，因此，写出来的文章必然就是平淡如流水，没有英语言，因此，写出来的文章必然就是平淡如流水，没有英语的味道。如果我们能够在单词的基础上，进一步想到与之的味道。如果我们能够在单词的基础上，进一步想到与之同义的词组，那么文章就会显得与众不同，更具有英语的同义的词组，那么文章就会显得与众不同，更具有英语的味道。味道。n 比如上面所说的比如上面所说的“重要的重要的”这个单词，当我们想到这个单词，当我们想到importantimportant的

7、时候，如果从语法角度再稍加考虑一下，我的时候，如果从语法角度再稍加考虑一下，我们会想到们会想到“be of importance”be of importance”。因为，语法中规定：形。因为，语法中规定：形容词等于容词等于ofof加这个形容词的名词形式。如果再提升一步，加这个形容词的名词形式。如果再提升一步，我们还学过一个常用的词组叫做我们还学过一个常用的词组叫做“play an important play an important role in-”role in-”。2 2、句式、句式n 除了采用词组，要使文章更具英语的味道，我们还需除了采用词组，要使文章更具英语的味道，我们还需要变换

8、句式。没有受过正规作文训练的考生，通常采用的要变换句式。没有受过正规作文训练的考生，通常采用的句式多为主谓宾、主系表。于是我们看到大多数的文章充句式多为主谓宾、主系表。于是我们看到大多数的文章充斥着这样的形式：斥着这样的形式：ni am a good boy, and i am a student. i study in shandong university, and i have three years experience in qilu hotel.n这样流水帐式的文章显然不能得到高分。这样流水帐式的文章显然不能得到高分。nn写作中阅卷人喜欢的句式有以下两种：写作中阅卷人喜欢的句式有以

9、下两种：n（1 1）是插入语）是插入语 n（2 2）是倒装。）是倒装。n（1 1）插入语。）插入语。n所谓插入语，英语中有两种形式。一种是有两个逗号所谓插入语，英语中有两种形式。一种是有两个逗号之间引起的成分称之为插入语；第二种是有两个半破折号之间引起的成分称之为插入语；第二种是有两个半破折号引起的成分称之为插入语。引起的成分称之为插入语。njinan, the spring city, is a famous tourist city.nother people may give us instrumental supportfinancial aid, material resources

10、, and needed servicesthat reduces stress by helping us resolve and cope with our problems.n插入语的作用主要有两个：插入语的作用主要有两个：n一个是突出主语，比如说：一个是突出主语，比如说：nhe, who would like to play basketball, is a good student. .n第二个作用是解释说明，比如说：第二个作用是解释说明，比如说：npeople, especially students, should work hard.（2）倒装）倒装n倒装是我们写作中需要用到的

11、。虽然略显俗套，但是倒装是我们写作中需要用到的。虽然略显俗套，但是却是很能满足阅卷人的主观感受的。却是很能满足阅卷人的主观感受的。n常用的倒装形式有以下几种：常用的倒装形式有以下几种：n nonly + 时间状语时间状语 nonly when all of us join in the efforts of eliminating cheating at all levels can we expect to have a cleaner society and a more beautiful future. n nonly + 介词词组介词词组 nonly by planning his

12、time carefully can he improve efficiency and make achievements. nonly in this way can we master the writing skills step by steps. n n 否定词位于句首否定词位于句首（hardly when; never; not only-,but also-; seldom） n在我一生当中很难遇到这样的人在我一生当中很难遇到这样的人 n seldom in my life have i met such a kind-hearted man. n 地点方位名词位于句首地点方位

13、名词位于句首 nin no other place in the world can one find such enthusiasm for applying for hosting the 2008 olympic games. 3 3、修辞、修辞n无论是汉语写作还是英语写作，修辞其实非常的重要。无论是汉语写作还是英语写作，修辞其实非常的重要。它是作者写作功底具体事例的展现。所谓修辞包括比喻、它是作者写作功底具体事例的展现。所谓修辞包括比喻、拟人、排比等等。这里仅举一个比喻例子，还是拿拟人、排比等等。这里仅举一个比喻例子，还是拿“重要重要的的”来举例。当你用完词组之后，如果你用上下面句子，

14、来举例。当你用完词组之后，如果你用上下面句子，则文章就会显得神采飞扬，试比较：则文章就会显得神采飞扬，试比较：nnthe bicycle is important for us.nthe bicycle is of importance for us.nthe bicycle plays an important role in our life.nthe bicycle, environmental friendliness vehicle, plays an important role in our life.nthe bicycle is like the air, water, an

35、l kinds of nutritious foodn第一句用人称名词作为主语开头，第二句则用第一句用人称名词作为主语开头，第二句则用there there bebe句型开头。这样既改变了主语谓语宾语单调句型，又句型开头。这样既改变了主语谓语宾语单调句型，又把想强调的意思突出出来。实际上，为了把文章写得生动把想强调的意思突出出来。实际上，为了把文章写得生动活泼，除了用主语开头外，还可以用句子的其他成分开头。活泼，除了用主语开头外，还可以用句子的其他成分开头。n1用副词开头用副词开头too often，students stray into the habit of cheating on te

38、短语开头nto pass the exam，you should work very hardn4 4、长短句交插、长短句交插n 长句和短句各有其优点和缺点。长句，因为使用的定长句和短句各有其优点和缺点。长句，因为使用的定语、状语较多，限制了概念的外延，增大了概念的内涵，语、状语较多，限制了概念的外延，增大了概念的内涵，所以比较精确、严密，但使用起来不够活泼简便。短句，所以比较精确、严密，但使用起来不够活泼简便。短句，由于字数少，直截了当，一般比较简洁、明快、有力，但由于字数少，直截了当，一般比较简洁、明快、有力，但不利于表达复杂的语义内容。在具体语言活动中，最好长不利于表达复杂的语义内容。在

39、具体语言活动中，最好长短句交替使用。这既体现了节奏上的要求，也是给文章润短句交替使用。这既体现了节奏上的要求，也是给文章润色的技巧之一。色的技巧之一。n（1）we can imagine the beautiful surroundings（2）there are many trees along the streets（3）there is a clean river in the city（4） there are many fishes in the river（5）there are willow trees on the one side（6）there are some piece
