篇4：图表类英语四级作文常用句型

图表类作文讲究“图面简单，寓意深刻”，它以图表/图画的形式给出提示，深层次信息则隐含在图表/图画之中，这种题型不仅需要考生描述图表/图画中的基本信息，更要求考生解读图表/图画中所隐含的深层含义，即文章主题。下面我们以2005年考研英语作文为例，谈谈图表作文的审题六要素：

Directions: Write an essay of 160~200 words based on the following drawing. In your essay, you should first describe the drawing, then interpret its meaning and give your comment on it. You should write it neatly on ANSWER SHEET 2（20 points）.

一审“要求”(Directions)

拿到作文题目时，考生要对题目的“Directions”(包括作文类型、写作篇章结构和篇幅长短等)做出适当分解，以求对作文要求及所规定的任务有一个清晰的了解。例如：从“Directions”中，考生可知这是一篇图画作文；写作字数应控制在160～200字之间；全文可按“三段式”谋篇布局：第一段描述图画内容(describe the drawing)，第二段说明图画所反映出的问题(interpret its meaning)，第三段提出自己的看法或建议(give your comment on it)。

二审“图表/图画”

考生要仔细观察图面，细心揣摩，牢牢把握图表中各个数据的变化和相互关系，以及认真判断图画中人或物的体貌表情特征和背景，确立人物之间、人物与背景之间的主要关系，以便准确掌握图表/图画所传达的信息，正确把握试题所涵盖的审题立意的角度。从以下画面中，考生可观察到老父亲衣着破旧、神情凄婉、身体缩成一团，像个“足球”般无奈地“立”在场地中央，而他的儿女——四个“守门员”，要么时尚袭人，要么一身休闲，要么西装革履，要么身壮体胖，分别围站在老人的东、西、南、北四个方向，他们个个表情严肃，严阵以待地站在球门前，似乎谁都不想让这个“足球”射进自己的“球门”。根据对图画的这番观察，很显然，本文审题立意的角度应考虑到老人与其子女之间的关系和目前所处的境况。

三 审“提示语”

图表/图画中的提示语，既是限制，又是启发；既是提示，又是暗示。考生一定要注意这些提示语中透露出来的信息，并加以利用。根据作文画面中的“养老‘足球赛’”提示语，考生可知三个儿子和一个女儿正进行着一场特殊的“足球赛”，他们个个蓄势待发，而“立”在场地中央的“足球”竟然是他们可怜的老父亲。人人都说“养儿防老”，可这四个儿女却在进行着一场“养老足球赛”，把父亲当作“足球”踢来踢去(The four children regard their father as a football to play with each other)，谁都不想让这个“足球”射进“自家门”(None of them is willing to raise their elderly father)，从中可进一步确定本文审题立意应从“子女如何对待老人(How to treat the elderly)”这个角度出发。

四审“主题”

图表/图画作文的主题是隐含在图面信息中的，分析时切忌就图论图、就事论事。要“以小见大”，“透过现象看本质”，把隐含的主题显现化。依据作文画面：从表象上看，三个儿子和一个女儿与父亲之间进行着一场“足球赛”，但透过表层意思、表面现象，通过与现实的联系，我们不难发现画面折射出的是一个十分普遍的社会现象(a common social phenomenon)，令人深思(thought-provoking)，应引起社会的极大关注(arouse the considerable concern of our society)，从而揭示了事物的本质，即它所隐含的主题——全社会都应孝敬老人(respect the elderly)，这是我们的传统美德(tradition)，对子女不孝敬老人的行为要进行严厉地批评和谴责(Such immoral behavior as abusing the aged should becastigated and condemned.)。

五审“文体”

“文体”狭义上指文学风格，广义上有两层含义：一是指文体的内涵为“文体风格”；二是指文体包括各种以语言为表达方式的话语体裁。我们知道，文章是以一定的体裁和一定的文体特征体现语言的。图表类作文是一种特殊的提示性作文，一般属于说明文或议论文。说明文主要有例证法、定义法、分类法、因果关系法、比较对照法和过程分析法；议论文则要注意论述的严谨性和逻辑性，旗帜要鲜明，立场要坚定。历年考研英语写作常常是以说明和议论两种方式互相补充，交叉考查的。例如这篇2005年的作文要求考生客观描述画面，说明画面内容以及提出自己的看法或建议。通过分析，我们可得出此文章既要求说明，又要求议论，属于说明性议论文。审定体裁后，考生还应明确在语言表达上所要选取的风格，例如判断该文是应该使用正式体还是口语体。2005年的作文体裁是一篇说明性议论文，因此所用句法和词汇应体现比较正式的文体风格。如“as is vividly portrayed in the drawing above”与“we can see from the picture”相比更为正式；“it goes without saying that”与“it is clear that”相比更为正式；“there is no denying to the obvious fact that”与“the obvious fact that”相比更为正式等等。因此考生在练习此类文章时可以多准备一些句型，以便在考试中灵活应用，使句式灵活多变。

六审“提纲”

2005年作文可采用三段行文：第一段（opening）：忠实客观地描述图画内容(The four children are reluctant to raise their old father. Instead，they regard their father as a football to play with.)不要就画论画，而是要以点带面、概括性地进行总体描述(What the picture reveals mirrors a common social phenomenon.)第二段(body)：正面说明孝敬老人(respect the elderly)的问题，这部分内容要体现本文的中心意旨(the aim is to reveal the fact that the children do not want to raise their parents)，揭示图画所隐含的主题(to respect the old is of great import-ance)，并对“孝敬老人”这一社会现象展开讨论；第三段(closing)：提出自己的看法或建议，考生要旗帜鲜明地表达自己的观点(it is urgent that a series of counter-measures should be adopted immediately)，并提出一些可行的、建设性的意见或建议(For one thing... For another...)。

综上所述，图表类作文开篇之“举”在于认真审题，只有这一步走正了、走好了，才有可能写出符合题意的作文。考生们在平时的复习过程中可以抽出一段时间专门练习审题，练习材料可以历年考研真题为主。俗话说“熟能生巧”，平时勤学多练，考试时就一定能取得理想的成绩！

Say No to Pirated Products

Piracy is currently becoming a severe problem, which happens to products like books,1

CDs and softwares in particular.So long as a new product is expected to sell well, its pirated counterparts will always unsurprisingly flood into our eyes.Why is piracy so rampant? First and foremost, pirates are madly allured by the huge profits from pirated products due t their considerably low cost.Second, in contrast to the original ones, the pirated products have much lower prices, which is more acceptable by most of the consumers.Last but not least, our government fails to take sufficient measures to prevent it.As a result of all these, piracy is prevailing, and it enriches the unlawful traders but only at the cost of the interests of authors, legitimate producers and even customers.Above all, it infringes both author’s intellectual property rights and legitimate producers’ copyrights.In addition, the poor quality of pirated products not only causes tremendous damage to author’s reputation but also misleads customers.Therefore, it is high time that piracy should be banned.In my view, a complete law system should be established and strictly carried out.The government should call on everyone to fight against piracy and drastically punish those involved in it.As for us consumers, we should develop our consciousness to resist pirated products.作业：

My Ideal Job

1.人们对职业各有不同的理想

2.我理想的职业是什么

3.我怎样为我理想的职业作准备

Harmfulness of Fake Commodities

1.目前社会上有不少假冒伪劣商品

2.为什么会有这种现象

篇8：化学专业英语常用句型例谈

一、分解反应句型

在无机化合物中碳酸氢盐、氯酸盐、硝酸盐、过氧化氢、碳酸等易于分解，这些化合物分解常需加热或催化剂，表示它们分解反应的词为decompose或decomposition，常用句型如下：

(1) When water containing HCO-3is heated, the bicarbonate ion rapidly decomposes to give carbonate, carbon dioxide, and water.

(2) When compounds containing nitrates are heated, they do not readily release all of the oxygen atoms in the compound.They decompose to give a compound that is a nitrite along with oxygen gas.

(3) When compounds containing chlorates are heated, they decompose to give the metal chloride and oxygen gas.

(4) Hydrogen peroxide undergoes decomposition in the presence of catalyst to produce oxygen gas and water.The iodide ion or MnO2catalyzes this reaction.

(5) Carbonic acid is a very unstable substance and decomposes to give carbon dioxide and water.

经常对具有分解反应的无机物加以综合，不仅有助于专业英语的学习，也有助于无机化学的学习。另外，某些金属碳酸盐、氢氧化物等也可发生分解反应。

二、歧化反应

歧化反应也是无机化学中的重要反应，三价猛和锰酸盐在溶液中会发生歧化反应，氯和溴在碱性介质中也易歧化，氧化亚铜在稀硫酸酸性条件下岐化为二价铜和金属铜。掌握一些无机物的歧化反应结合化合物的名称和两个英语词汇disproportionation和disproportionate可以用专业英语很好地描述该反应。

(1) Mn3+is unstable;its disproportionation is spontaneous.

(2) Manganate ion is also instable in unstable in acidic solution;its disproportionation gives permanganate and manganese (II) ion.

(3) In the sodium carbonate solutions, bromine disproportionates to form sodium bromide and sodium bromate.

(4) Chlorate salts form when Cl2disproportionates in hot alkaline solutions.Hypochlorites form in cold alkaline solutions.

三、中和反应

在无机反应中，酸碱中和形成盐发生中和反应，常用的词汇有名词neutralization和动词neutralize。它们在句子中的位置及描述该反应的句型如下：

(1) CaCl2is a salt formed during the neutralization reaction of hydrochloric acid with calcium hydroxide.

(2) A salt and water are formed when sulfuric acid neutralizes sodium hydroxide.

(3) A neutralization reaction involves the combination of hydrogen ions and hydroxide ions to form water.

(4) Ammonia undergoes neutralization reaction with hydrochloric acid to form ammonium chloride.

四、还原反应句型

金属的制备或冶炼等常用还原法，reduction和reduce可用于描写还原反应。典型的例句如下：

(1) After purification, the tin (IV) oxide is reduced with carbon to produce tin metal.

(2) Calcium, strontium, and barium are obtained by the reduction of their oxides with aluminum.

(3) Tin (II) chloride is a good reducing agent and is used in the quantitative analysis iron ores to reduce Fe (III) to Fe (II) in aqueous solution.

(4) Pb (IV) compounds tend to undergo reduction to com pounds of Pb (II) and therefore good oxidizing agents.

(5) Chromium (II) compounds can be prepared by the reduction of Cr (III) compounds with zinc in acidic solution.

(6) Pure Cr can be obtained in small amounts by reducingCr2O3with Al in a reaction similar to the thermite reaction.

(1) Both Cu and Ag react with concentrated H2SO4or HNO3.The metals are oxidized to Cu2+and Ag+, respectively, and the reduction products are SO2and NO.

(2) The HNO3oxidizes the metal and Cl-from the HCl promotes the formation of the stable complex ion[AuCl4]-.

(3) Concentrated H2SO4is a sufficiently strong oxidizing agent to oxidize Br-to Br2and I-to I2.

(4) Then sulfur trioxide is produced by oxidizing SO2in an exothermic, reversible reaction.

(5) Sulfites are good reducing agents and easily oxidized by O2.

(6) Ammonia and CuO can Undergo oxidation-reduction to form nitrogen.

(7) When copper reacts with dilute nitric acid, Copper is oxidized to copper (II) nitrate, and nitric acid is reduced to nitrogen monoxide.

(8) Firstly, ammonia is converted to NO by oxidation in the presence of platinum, followed by reaction with air and then waterto yield nitric acid.

六、化合物电离

酸、碱、盐在水中电离出氢离子、氢氧根离子、正离子或阴离子。它们与化学反应不同，没有形成新的物质，只是离解出离子，可以用ionize和dissociate来描述。

(1) When ammonia dissolves in water, the aqueous solution partially ionize into ammonium ions and hydroxide ions.

(2) Nitric acid is a strong acid, it is completely ionized to hydrogen ion and nitrate ion.

(3) Water very slightly ionize to hydronium and hydroxide ions.
