篇2:初中英语常用句型

1. There be 结构

there be 结构和have has结构翻译成汉语都是“有”的意思,但含义不同。have (has)表示“某人拥有某物”,there be而结构表示“某人或某物存在于某地或某时”。

There are some apple trees in the garden.

We have some apple trees in the garden.

there be 结构中的动词 动词与后面的主语在数的方面保持一致。如果句中的主语是并列主语,即有两个或两个以上的人或物作主语,那么一般说来动词的数应与第一个主语的数保持一致。如:

There is a green apple and two oranges in the fruit bowl.

There are two oranges and a green apple in the fruit bowl.

2. I think he is very old.

(1)否定句

一些表示个看法的动词,如等引导宾语从句时,如果从句为否定句,那么否定形式应该表现在主句中,即否定这些动词本身。如:

I don’t think he is very old.

I didn’t think Wang Hai would enter for the high jump.

(2)反意疑问句

这些动词带有宾语从句构成反意疑问句时,根据主句主语的不同可分为两种情况:当主语是第一人称时,则缩略问句应与宾语从句的主、谓保持一致,但如果主句表现为否定为形式时,缩略问句要用肯定形式;当主句的主语是第二或第三人称时,缩略问句应该与主句保持一致。如:

I don’t think he has finished the work, has he?

You think my brother told a lie yesterday, don’t you?

3. That’s right. That’s all right. All right.

“That’s right.”表示“对、正确”。一般在对话中用于肯定对方的回答或表示赞同对方的说法。 “That’s all right.” 是回答感谢话或道歉话的用语,意思是“没关系,不用谢”,相当于“You are welcome”、“That’s OK”或 “Not at all”“All right”一般用于同意别人的请求,是“好的、可以”的意思。如:

A: I think the correct answer is two. B: That’s right.

A: I am sorry I left your notebook at home. B: That’s all right.

4. He’s up there in the tree with Bill.

这句话的主语是“he”,“with Bill”不是主语,而是表示一种伴随状态,所以请注意谓语要和主语在数和人称称保持一致。一般在句子中我们经常用“with+名词”这种结构表示“有、带着或伴随着”的意思。如:

He went to the concert with me.=He and I went to the concert.

She answered me with a smile.

He went to sleep with the bedroom light on.

5. It’s time…

这一句型用来表示“是。。。的时间了,该。。。了”。一般有以下几种形式:

(1) It’s time to +动词原形

(2) It’s time for sb. +动词原形

(3) It’s time for +名词

如:It’s time to go to school.=It’s time for school.

It’s time for us to go to school.

6. What’s wrong with you?

这句话的意思是“你怎么了?”,既可表示问身体有什么不舒服,也可以表示问出了什么事,介词后还可以跟物品名称,表示问某样东西怎么了(是否出了什么毛病)。与其类似的句型还有:“What’s the matter with…? / What’s the trouble with…?”这三个句型在使用时要注意wrong是形容词,所以在它有前面不加冠词,而matter和trouble都是名词,在它们前面要加定冠词。如

What’s wrong with Bill?

What’s the matter (the trouble) with Bill?

7. They looked like saucers.

在本句中like是个介词,解释是“像。。。”,常和动词 be或 look连用。请注意不要错把它当成动词“喜欢”。

8. You had better come early next time.

此句中的had better是一种习惯用法, 意思是 “最好…”成, 一般用来表示向别人提建议或劝告.这一句经常可以与祈使句或带有情态动词should 的句子进行替换.在使用had better 时请注意以下几点: (1) 它没有人称、时态和数量的变化。(2)它的后面只能跟动词原型。(3)它的否定式为had better not,后面同样只能跟动词原型在疑问句中,通常是把had提到主语之前。如

We had better not go fishing on such a windy day.

9. be + adj. + (for somebody) to do (something)

在此句型中谓语动词一般不用被动语态。同时请注意动词不定式都有动宾关系, 因此如果不定式中的动词是不及物动词,那么它的后面一定加上适当的介词。

The problem is not very difficult for me to work out.

10. I hope… / I wish…

Hope 与wish 都可以解释为“希望”,但它们所表达的意思和用法都有所不同。 在意思上Hope所表达的愿望是比较实际的,是可能实现的,而 wish所表达的是不太可能实现的梦想, 所以wish引导的宾语从句大多用虚拟的语气。在用法上它们的唏不完全相同,区别在于wish可以用于wish sb. to do, 而hope没有这种用法。:,

They hope to win the game in the afternoon.

We all wish him to bring us the good news.

11. My dad will come back in two days.

“in + 一段时间”常用来表示将来的一段时间以后,对它提问用 “how soon” 。如果表示将来的某个时间点以后,一般用“after +某个点时间”,对它提问要用 “when / what time”。如:

How soon will you finish your homework?

I will finish my homework in an hour.

When / What time will you come back?

I will come back after dinner.

12. I’m afraid…

I’m afraid…常用于表达与别人意见不同后拒绝别人的请求,有时也可以用在表示不肯定或推测的话前面,是口语中十分常用的短语。它的后面可以接从句,也可以加或。如

A: Must I hand in the report today?

B: I’m afraid you must

“be afraid of +名词或动名词”的用法也很常用。表示“害怕”。如:

She is afraid of going out at night.

13. Sorry, I forgot to tell you that.

在英语中有一些动词,它们的后面可以跟动词不定式,也可跟动名词,而且两种情况所表达的意思不同,如:

(1)与的用法基本相同。它们后面跟不定式时表示不定式所表示的动作还没发生;如果后面跟动名词,那么表示动作已经发生过了。如:

He forgot to return the money to me. 他忘记还钱给我。(表示钱还没有还。)

He forgot returning the money to me.他忘记已经把钱还给我了。(表示钱已经还了,但他忘记了这件事。)

(2) stop后面跟不定式表示停下来去做别一件事,如果加动名词就表示停止这个动作。如:

Please stop talking and listen tome. 请不要讲话,听我说。

Please stop to have a rest 请停下来休息一下。

14. This one is much better than that one.

英语中的形容词或副词在使用时都不得有比较结构。一般来说它们有三个级别:原级、比较级和最高级。

(1)原级比较

初中阶段常用的原级比较句型为:as…as…, not as (so)…as…。使用时注意它们的.含义,as…as… 表示“和。。。一样”,而它的否定结构表示“不如。。。”。如

Is the Huanghe River as long as the Nile?

He does not work so hard as his brother.

(2)最常用的比较级用法是“比较级别+ than ”。另外两个相同的比较级用连接起来可以表示“越。。。越。。。”。如果要表示“两个中较为。。。的一个” ,在比较级之前要加一个the,一般可以修饰比较级的有:much, far, a little, a bit, even, still.

It is even colder than it was last month.

More and more people are helping fight pollution.

His handwriting is better than any other student in his class.

(3)使用最高级的结构一般为“归高级+比较范围”。这个比较范围内应饱含主语。如果比较范围与主语是同类的话,可以用等介词引出,如果他们不是同类的话,一般用引出。一般来说,形容词的最高级前一定要加定冠词,而副词的最高级前可以加也可以不加。如果要表示“第几。。。”,可以在最高级前面加序数词。如:

Among all the sports I like soccer best.

I am the eldest girl in my family.

15. (not)…until (till)

在这一句型结构中until (till) 引导的是时间状语(从句),因此从句中不能用将来时,只能用一般现在时代替。如果主句的谓语动词或until (till)前面的动词是一个瞬间动词,那么该动词必须用否定形式。一般地来说until和till的意思与用法都基本相同,唯一的区别在于可以置于句首,而不能。如:

He watched TV until (till) his parents came back.

We couldn’t go back home until the rain stopped.

16. be pleased…

这个短语后面既可以另动词不定式,也可以加适当的介词。 加不定式be pleased to do表示“做......很高兴”, 而加介词 be pleased with / at / by......表示“对......感到很高兴,很满意。”如:

We are pleased to plant trees by the river every spring.

My parents are pleased with my hard work.

17. You should go out instead of staying at home.

Instead of 可解释为“代替,而不是”,介词 of后面可以跟名词或动名词。有时没有必要说出被代替的人或物,也可以只用instead

He stayed at home to read the book instead of going out to play basketball.

If you don’t want to go, I can go there instead.

18. I don’t like it any more.

No more, not any more, no longer, not any longer这几个短语都表示“不再......,再也不......”。在使用时请注意它们在句子中的位置。如:

篇3:高考英语作文常用句型归纳

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。

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。

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.
