篇1：初中英语作文常用的句型

such+名词性词组+that…

So+形容词/副词+that…——如此……以致……

例如：(1)She is such a good teacher that we all love her.她是一个好老师，我们都爱她。

(2)It was such a hot day that they didn’t go out for a walk as usual.这么热的天气，他们没有像往常一样去散步。

注意点：

1.such+a+形容词+名词+that…，可以改写成：so+形容词+a+名词+that…，例句(1)可以改写成：She is so good a teacher that we all love her.2.在such+形容词+名词复数或不可数名词+that…结构中，形容词如果是many/few或much/little时，用so不用such，即：so+many/few+可数名词复数+that…，so+much/little+不可数名词+that…

(1)There are so many people in the room that I can’t get in.房间里人太多，我进不去。

(2)The man has so much money that he can buy a car.那人很有钱，他能买一辆小汽车。

(4)Neither you nor he is right.你和他都不对。

(5)Both Jack and Tim are English.Jack和Tim是英国人。

注意点：

当这几个句型连接主语时，谓语动词的人称和数要考虑“就近原则”，对比both…and… 来记忆，both…and…连接主语时视为复数。

句型(三)

Enough+名词+to do…——有足够的……做某事

形容词/副词+enough+to do …——足够……做某事

例如：(1)There is enough room to hold these people to have a meeting.有足够的地方容下这些人开会。

(2)The boy is strong enough to carry the heavy box.这个男孩力气够大，能搬动这只箱子。

注意点：

enough做副词修饰形容词或副词时，放在所修饰词的后面，句子可以用so…that…句型改写。例句(2)可以改写为：The boy is so strong that he can carry the heavy box.这个男孩力气很大，能搬动这只箱子。

这是一个否定句型，不能在不定式前加 not，可以用so…that…结构改写，例如例句(1)可以改写成：I was so excited that I couldn’t say a word.句型(五)

So that …——以便/以致……

例如：(1)They studied hard so that they could pass the exam.他们学习很努力，为了能通过考试。

(2)They started early so that they caught the early bus.他们起得很早，结果赶上了早班车。

注意点：

在例句(1)中,是引导目的状语；在例句(2)中，是引导结果状语。一般来讲，从句中含有情态动词的，为目的状语。无情态动词的，为结果状语。

句型(六)

祈使句+then/or/and+陈述句

例如：(1)Work hard,and/then/and then you will live a happy life.努力工作，你就会过上幸福生活。

(2)Hurry up, or we will be late for school.快点，否则我们上学就迟到了。注意点：

以上句型都可以用条件状语从句来改写。例句(2)可以改写成：If we don’t hurry up,we’ll be late for school.句型(七)

(1)It’s time for sth.是干某事的时间了。

It’s time(for sb)to do sth.该干某事了。

(2)It’s time for us to go to school.我们该上学了。

(3)It’s high time that you went to bed.你该上床休息了。

注意点：

在句型(3)中，可以在time前加rush、high等修饰词，这个句型是虚拟语气的一种，含有“稍迟一点”的含义。而(2)则是“正是干某事的时候”。

句型(八)

(1)It takes sb.Some time to do sth.干某事花某人一些时间

(2)sb.spend some time on sth./(in)doing sth.某人花时间在某事上/花时间干某事

(5)I spent 298 yuan on the bike.我买这辆自行车花了298 元。

(6)I paid 298 yuan for the bike.我花了298元买这辆自行车。

注意点：cost主语一般为物；spend、pay主语一般为人。例(1)中it 用做形式主语，动词不定式为真正主语。

句型(九)

(1)Why not do…?为什么不干某事？

(2)Let’s do …让我们干某事吧。

(2)Shall we go out for a walk?No, let’s go to the zoo.我们去散步怎么样？不，我们去动物园吧。

(3)Will you please fetch some chalks for me?请你给我拿些粉笔，好吗？

(4)What about singing an English song? Wonderful!唱首英语歌曲怎么样？好极了！

注意点：这些句型都是表示“建议”的句子，可视为同义句。

句型(十)

(1)Let’s go out for a walk,shall we?让我们出去散步，好吗？

(2)Read the book carefully,will you?认真读书，好吗？

注意点：在这两个句型中，(2)所代表的祈使句，一般用will you构成反意疑问句。在(1)中Let’s表示包括“我”在内，用shall we，但若是let us，表示不包括“我”在内，则用will you。

例如：Let us go out for a walk,will you?你让我们出去散散步，好吗？

句型(十一)

So+be/助动词/情态动词+主语——也……

Neither/Nor+be/助动词/情态动词+主语——也不……

例如：(1)He can sing a lot of English songs,so can she.他会唱很多英语歌曲，她也是。

(2)She speaks English very well,so do I.她英语说得好，我也是。

(3)Li Lei hasn’t read this book,neither has Lin Feng.李蕾没看过这本书，林风也没看过。

注意点：这两个句型都表示和前面所陈述的内容相同，用倒装句。要注意和 “so+主语+be/助动词/情态动词——确实是”相区别，试对比一下例(2)：A：She speaks English very well.她英语说得很好。

B：so she does.确实是这样。

句型(十二)

I don’t think his answer is right.我认为他的答案不对。

例如：(1)I can’t believe she is right.我相信她是不对的。

(2)You don’t think they will come tomorrow, do you?你认为他们明天不会来，是吗？

注意点：Think、believe、suppose 等接宾语从句时，表示否定时否定主句。变为反意疑问句时，若主语是第一人称，简短问句与宾语从句的主谓语保持一致，若主句主语是其他人称，与主句主谓语保持一致。例(1)变为反意疑问句应为：I can’t believe she is right, is she?

篇4：商务英语常用句型浅析

摘要：商务英语有自己独特的文体特征和句型特色。其实很多句型都是由规律可循的。本文精选了商务英语中的常用句型，并进行了英汉互译，还对每个常用句子进行了解析。

关键词：商务英语；常用句型；分析

中图分类号：H314 文献标识码：A 文章编号：1671-864X（2016）11-0156-01

1、In view of the unusually big size of our order， we hope you will offer us more favorable terms.

译文：鉴于我方的大量订购，我希望贵方能提供更优惠的付款条件。

分析：通常，大批量的订购能获得价格方面的优惠。如果彼此之间早就进行过很多次交易，索要优惠一般都会得到满足。

2、In order to expand mutual business， well accept usance L/C this time.

译文：为了扩大双方业务，这次我们将接受远期信用证。

分析：远期信用证其实也就是非即期信用证。

3、Its our usual practice to require payment by sight L/C， so we cant set a precedent（先例） for this transaction.

译文：即期信用证支付是我方的通常做法，这笔交易我们不能破例。

分析：这是常用的谈判技巧，拒绝对方要求的常用理由。一般来说，除非是双方有长期业务关系，否则一般不会轻易破例。

4、In view of the large amount involved in this transaction， we hope youll agree to our request for installment payment.

译文：由于这笔交易的货款数目巨大，我们希望贵方能同意我方分期付款的要求。

5、Wed like to make a down payment first， and then after the delivery， we pay off the rest of them in four payments.

译文：我方希望先付定金，其余款项在发货后分四次付清。

分析：通常来说余款是一次结清的，但是如果是买方市场的话，卖方也可能做出一些让步。

6、As you usually clear your accounts promptly， we wondered why the July account for US $5，400 was not paid last month when it was due.

译文：由于你方一般都很快结账，我们想知道7月份的5400美元上月已到期，你方为何还未支付。

7、With an eye to future business， well adopt payment by equal installments within three months.

译文：关于支付方式，我们只接受保兑的，不可撤销的信用证。

10、In compliance with your request， we exceptionally accept delivery against D/P at sight， but this should not be regarded as a precedent.

译文：按你方要求，我们破例接受即期付款交单，但只此一回，下不为例。

分析：即使最后被迫让步，也不要让人感觉自己毫无主见和地位。也是要给对方一点适当的回击，下不为例就是很好用的四个字。不要让对方觉得得到照顾是理所当然的。

11、除非你方能设法降低价格，否则成交希望很小。

译文：Business opportunity is rather remote unless you can see your way to reduce your prices.

分析：这一句语气很强硬，通常用于最后通牒。

12、相关信用证应由卖方可以接受的第三国银行开出。

译文：The relative L/C should be issued through a third country bank acceptable to the seller.

13、在签合同之前，我们有必要讨论支付方式。

译文：Its necessary for us to discuss the terms of payment before concluding this transaction.

分析：这是准备商议支付方式之前的一句套话。

14、为保证你方连续生产和合同中规定的准时交货，我方同意履行以下支付条款中规定的义务。

译文：In order to guarantee your continuous production and punctual shipment stipulated under this contract， we agree to excute the obligations specified in the following payment terms.

分析：常用的商務套话。其实商务英语中很多句子都是由规律可循的，我们要去发现和抓住这些规律，这样就能更好理解商务语言。

15、由于贵方呆板的支付条件，我们抱歉双方已无磋商余地。

译文：We very much regret that on account of your rigid payment terms， there is no room for negotiation.

分析：这也是最后交易谈崩的常用句式。

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.

(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.

五、氧化反应句型

硝酸、浓硫酸、高锰酸钾、重铬酸钾等都是强氧化剂，有关它们的反应涉及氧化反应，常见氧化反应句型如下：

(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.

(4) Hydrogen sulfate ions dissociate in water into hydrogen ion and sulfate.

(5) Hydrosulfuric acid is a weak acid, it can partly ionize to hydrogen sulfide ion.

(6) Sulfuric acid is a strong diprotic acid and it almost completely ionize in water to hydrogen sulfate ion in the first step.
