SCI论文写作之12个常用句式
SCI论文写作之12个常用句式1. 在Introduction里面经常会使用到的一个句子：很多文献已经讨论过了。
A. Solar energy conversion by photoelectrochemical cells has been intensively investigated. (Nature 1991, 353, 737 - 740 )B. This was demonstrated in a number of studies that showed that composite plasmonic-metal/semiconductor photocatalysts achieved significantly higher rates in various photocatalytic reactions compared with their pure semiconductor counterparts.C. Much work so far has focused on wide band gap semiconductors for water splitting for the sake of chemical stability.（DOI:10.1038/NMAT3151）D. Recent developments of Lewis acids and water-soluble organometallic catalysts have attracted much attention.（Chem. Rev. 2002, 102, 3641−3666）E. An interesting approach in the use of zeolite as a water-tolerant solid acid was described by Ogawa et al （Chem.Rev. 2002, 102, 3641−3666）F. Considerable research efforts have been devoted to the direct transition metal-catalyzed conversion of aryl halides toaryl nitriles. (J. Org. Chem. 2000, 65, 7984-7989)G. There are many excellent reviews in the literature dealing with the basic concepts of the photocatalytic processand the reader is referred in particular to those by Hoffmann and coworkers,Mills and coworkers, and Kamat.(Metal oxide catalysis,19,P755)H. Nishimiya and Tsutsumi have reported on（proposed）the influence of the Si/Al ratio of various zeolites on the acid strength, which were estimated by calorimetry using ammonia. (Chem.Rev. 2002, 102, 3641−3666)2. 正如下文将提到的...A. As will be described below（也可以是As we shall see below）, as the Si/Al ratio increases, the surface of the zeolite becomes more hydrophobic and possesses stronger affinity for ethyl acetate and the number of acid sites decreases.（Chem. Rev. 2002, 102, 3641−3666）B. This behavior is to be expected and will be further discussed below.(J. Am. Chem. Soc., 1955, 77, 3701–3707)C. There are also some small deviations with respect to the flow direction, which we will discuss below. （Science, 2001, 291, 630-633）D. Below, we will see what this implies.E. Complete details of this case will be provided at a later time.E. 很多论文中，也经常直接用see below来表示，比如：The observation of nanocluster spheres at the ends of the nanowires is suggestive of a VLS growth process (see below). (Science, 1998, 279, 208-211)3. 相反/不同于A. On the contrary, mononuclear complexes, called single-ion magnets (SIM), have shown hysteresis loops of butterfly/phonon bottleneck type, with negligible coercivity, and therefore with much shorter relaxation times of magnetization. (Angew. Chem. Int. Ed., 2014, 53: 4413–4417)B. In contrast, the Dy compound has significantly larger value of the transversal magnetic moment already in the ground state (ca. 10−1 μB), therefore allowing a fast QTM. （Angew. Chem. Int. Ed., 2014, 53: 4413–4417）C. In contrast to the structural similarity of these complexes, their magnetic behavior exhibits strong divergence. (Angew. Chem. Int. Ed., 2014, 53: 4413–4417)D. Contrary to other conducting polymer semiconductors, carbon nitride is chemically and thermally stable and does not rely on complicated device manufacturing. (Nature materials, 2009, 8(1): 76-80.)E.Unlike the spherical particles they are derived from that Rayleigh light-scatter in the blue, these nanoprisms exhibit scattering in the red, which could be useful in developing multicolor diagnostic labels on the basis not only of nanoparticle composition and size but also of shape. (Science 2001, 294, 1901-1903)4. 发现，阐明，报道，证实可供选择的词包括：verify, confirm, elucidate, identify, define, characterize, clarify, establish, ascertain, explain, observe, illuminate, illustrate，demonstrate, show, indicate, exhibit, presented, reveal, display, manifest，suggest, propose, estimate, prove, imply, disclose，report, describe，facilitate the identification of 举例：A. These stacks appear as nanorods in the two-dimensional TEM images, but tilting experiments confirm that they are nanoprisms. (Science 2001, 294, 1901-1903)B. Note that TEM shows that about 20% of the nanoprisms are truncated. (Science 2001, 294, 1901-1903)C. Therefore, these calculations not only allow us to identify the important features in the spectrum of the nanoprisms but also the subtle relation between particle shape and the frequency of the bands that make up their spectra. (Science 2001, 294, 1901-1903)D. We observed a decrease in intensity of the characteristic surface plasmon band in the ultraviolet-visible (UV-Vis) spectroscopy for the spherical particles at λmax = 400 nm with a concomitan t growth of three new bands of λmax = 335 (weak), 470 (medium), and 670 nm (strong), respectively. (Science 2001, 294, 1901-1903)E. In this article, we present data demonstrating that opiate and nonopiate analgesia systems can be selectively activated by different environmental manipulations and describe the neural circuitry involved. (Science 1982, 216, 1185-1192)F. This suggests that the cobalt in CoP has a partial positive charge (δ+), while the phosphorus has a partial negative charge (δ−), implying a transfer of electron density from Co to P. (Angew. Chem., 2014, 126: 6828–6832)5. 如图所示A. GIXRD patterns in Figure 1A show the bulk structural information on as-deposited films.B. As shown in Figure 7B,the steady-state current density decreases after cycling between 0.35 and 0.7 V, which is probably due to the dissolution of FeOx.C. As can be seen from parts a and b of Figure 7, the reaction cycles start with the thermodynamically most favorable VOx structures（J. Phys. Chem. C 2014, 118, 24950−24958）6. 这与XX能够相互印证A. This is supported by the appearance in the Ni-doped compounds of an ultraviolet–visible absorption band at 420–520nm (see Fig. 3 inset), corresponding to an energy range of about 2.9 to 2.3 eV.B. This is consistent with the observation from SEM–EDS. (Z.Zou et al. / Chemical Physics Letters 332 (2000) 271–277)C. This indicates a good agreement between the observed and calculated intensities in monoclinic with space groupP2/c when the O atoms are included in the model.D. The results are in good consistent with the observed photocatalytic activity...E. Identical conclusions were obtained in studies where the SPR intensity and wavelength were modulated by manipulating the composition, shape,or size of plasmonic nanostructures.F. It was also found that areas of persistent divergent surface flow coincide with regions where convection appears to be consistently suppressed even when SSTs are above 27.5°C.7. 值得注意的是...A. It must also be mentioned that the recycling of aqueous organic solvent is less desirable than that of pure organic liquid.B. Another interesting finding is that zeolites with 10-membered ring pores showed high selectivities (>99%) to cyclohexanol, whereas those with 12-membered ring pores, such as mordenite, produced large amounts of dicyclohexyl ether. (Chem. Rev. 2002, 102, 3641−3666)C. It should be pointed out that the nanometer-scale distribution of electrocatalyst centers on the electrode surface is also a predominant factor for high ORR electrocatalytic activity.D. Notably, the Ru II and Rh I complexes possessing the same BINAP chirality form antipodal amino acids as the predominant products. (Angew. Chem. Int. Ed., 2002, 41: 2008–2022)E. Given the multitude of various transformations published, it is noteworthy that only very few distinct activation methods have been identified. (Chem. Soc. Rev., 2009, 38, 2178-2189)F. It is important to highlight that these two directing effects will lead to different enantiomers of the products even if both the “H-bond-catalyst” and the catalyst acting by steric shielding have the same absolute stereochemistry. (Chem. Soc. Rev., 2009, 38, 2178-2189)G. It is worthwhile mentioning that these PPNDs can be very stable for several months without the observations of any floating or precipitated dots, which is attributed to the electrostatic repulsions between the positively charge PPNDs resulting in electrosteric stabilization.(Adv. Mater., 2012, 24: 2037–2041)8. ...仍然是个挑战A. There is thereby an urgent need but it is still a significant challenge to rationally design and delicately tail or the electroactive MTMOs for advanced LIBs, ECs, MOBs, and FCs.（Angew. Chem. Int. Ed.2 014, 53, 1488 –1504）B. However, systems that are sufficiently stable and efficient for practical use have not yet been realized.C. It remains challenging to develop highly active HER catalysts based on materials that are more abundant at lower costs. (J. Am. Chem. Soc., 2011, 133, 7296–7299)D. One of the great challenges in the twenty-first century is unquestionably energy storage. (Nature Materials 2005, 4, 366 - 377 )9. 众所周知A. It is well established (accepted) / It is known to all / It is commonly known that many characteristics of functional materials, such as composition, crystalline phase, structural and morphological features, and the sur-/interface properties between the electrode and electrolyte, would greatly influence the performance of these unique MTMOs in electrochemical energy storage/conversion applications.（Angew. Chem. Int. Ed.2014,53, 1488 –1504）B. It is generally accepted (believed) that for a-Fe2O3-based sensors the change in resistance is mainly caused by the adsorption and desorption of gases on the surface of the sensor structure. (Adv. Mater. 2005, 17, 582)C. As we all know, soybean abounds with carbon, nitrogen and oxygen elements owing to the existence of sugar, proteins and lipids. (Chem. Commun., 2012, 48, 9367-9369)D. There is no denying that their presence may mediate spin moments to align parallel without acting alone to show d0-FM. (Nanoscale, 2013, 5, 3918-3930)10. 我们的研究可能在哪些方面得到应用A. Our findings suggest that the use of solar energy for photocatalytic water splitting might provide a viable source for ‘clean’ hydrogen fuel, once the catalytic efficiency of the semiconductor system has been improved by increasing its surface area and suitable modifications of the surface sites.B. Along with this green and cost-effective protocol of synthesis, we expect that these novel carbon nanodots have potential applications in bioimaging and electrocatalysis.(Chem. Commun., 2012, 48, 9367-9369)C. This system could potentially be applied as the gain medium of solid-state organic-based lasers or as a component of high value photovoltaic (PV) materials, where destructive high energy UV radiation would be converted to useful low energy NIR radiation. (Chem. Soc. Rev., 2013, 42, 29-43)D. Since the use of graphene may enhance the photocatalytic properties of TiO2 under UV and visible-light irradiation, graphene–TiO2 composites may potentially be used to enhance the bactericidal activity. (Chem. Soc. Rev., 2012, 41, 782-796)E. It is the first report that CQDs are both amino-functionalized and highly fluorescent, which suggests their promising applications in chemical sensing.(Carbon, 2012, 50, 2810–2815)11. 什么东西还尚未发现/系统研究A. However, systems that are sufficiently stable and efficient for practical use have not yet been realized.B. Nevertheless, for conventional nanostructured MTMOs as mentioned above,some problematic disadvantages cannot be overlooked.（Angew. Chem. Int. Ed.2014,53, 1488 – 1504）C. There are relatively few studies devoted to determination of cmc values for block copolymer micelles. (Macromolecules 1991, 24, 1033-1040)D. This might be the reason why, despite of the great influence of the preparation on the catalytic activity of gold catalysts, no systematic study concerning the synthesis conditions has been published yet.(Applied Catalysis A: General2002, 226, 1–13)E. These possibilities remain to be explored.F. Further effort is required to understand and better control the parameters dominating the particle surface passivation and resulting properties for carbon dots of brighter photoluminescence. (J. Am. Chem. Soc., 2006, 128 , 7756–7757)12. 如何指出当前研究的不足A. Although these inorganic substructures can exhibit a high density of functional groups, such as bridging OH groups, and the substructures contribute significantly to the adsorption properties of the material, surprisingly little attention has been devoted to the post-synthetic functionalization of the inorganic units within MOFs. (Chem. Eur. J., 2013, 19: 5533–5536.)B. Little is known, however, about the microstructure of this material. (Nature Materials 2013,12, 554–561)C. So far, very little information is available, and only in the absorber film, not in the whole operational devices. （Nano Lett., 2014, 14 (2), pp 888–893）D. In fact it should be noted that very little optimisation work has been carried out on these devices. (Chem. Commun., 2013, 49, 7893-7895)E. By far the most architectures have been prepared using a solution processed perovskite material, yet a few examples have been reported that have used an evaporated perovskite layer. (Adv. Mater., 2014, 27: 1837–1841.)F. Water balance issues have been effectively addressed in PEMFC technology through a large body of work encompassing imaging, detailed water content and water balance measurements, materials optimization and modeling, but very few of these activities have been undertaken for anion exchange membrane fuel cells, primarily due to limited materials availability and device lifetime. (J. Polym. Sci. Part B: Polym. Phys., 2013, 51: 1727–1735)G. However, none of these studies tested for Th17 memory, a recently identified T cell that specializes in controlling extracellular bacterial infections at mucosal surfaces. (PNAS, 2013,111, 787–792)H. However, uncertainty still remains as to the mechanism by which Li salt addition results in an extension of the cathodic reduction limit. (Energy Environ. Sci., 2014, 7, 232-250)I. There have been a number of high profile cases where failure to identify the most stable crystal form ofa drug has led to severe formulation problems in manufacture. (Chem. Soc. Rev., 2014, 43, 2080-2088)J. However,these measurements systematically underestimate the amount of ordered material. ( Nature Materials 2013, 12, 1038–1044)（注：可编辑下载，若有不当之处，请指正，谢谢!）。

SCI科技论文写作常用句型大全
S C I科技论文写作常用句型大全Revised as of 23 November 2020一．好的论文题目是成功的一半好的论文，每一个部分都需要精雕细琢。
我们先来看看Science, Nature 子刊上用的都是些什么题目，到底这些题目暗含哪些玄机以下是从2016年发表的论文中随机挑选的一些题目，我将其做了一下简单的分类：1. Water splitting–biosynthetic system with CO2reduction efficiencies exceeding photosynthesis. (Science, 2016, 352, 1210)类似: Scalable water splitting on particulate photocatalyst sheets with a solar-to-hydrogen energy conversion efficiency exceeding1%(Nature Materials 2016,15,611-615)这种题目适合哪类文章适合于那种性能极其显着的文章（可以创纪录的文章），比如说Nocera et al. 的Science, 2016, 352, 1210，直接与光合作用进行对比，给人的震撼是非常强的。
这种对比效果能够一下子抓住人们的眼球，吸引着读者进行阅读。
要点：使用这样的题目首先你的实验结果得够牛，你对于实验结果要足够自信，对于背景知识的了解得要足够深。
因为取这样的题目意味着你要真正达到了某一个高度。
如果明明有很多大海在那里，你个小池塘和小水坑进行比较，那么会闹笑话的。
Quantifying the promotion of Cu catalysts by ZnO for methanol synthesis (Science,2016, 352, 969-974.)Exploring the origin of high optical absorption in conjugated polymers.

SCI写作必备语法专题四特殊句式第一部分倒装句主语和谓语有两种顺序：一是主语在前，叫自然语序。
反之，如果谓语在主语前就是倒装语序，又分全部倒装和部分倒装。
全部倒装是把全部谓语放在主语之前，部分倒装是把助动词或情态动词放在主语之前。
一、全部倒装1.there be句型：可以用在这类句型中的动词除be外,还可用live，happen，exist，remain，stand等等作这类句型的谓语。
如：There are many students in the classroom.教室里有许多学生。
Long，long ago there lived a king who loved horses very much.很久很久以前，有一位国王，他非常喜欢马。
There happened to be nobody in the bedroom when the fire broke out.起火的时候，碰巧房间里面没有人。
2.Here/There/Now＋vi.（常为come,go）＋主语（必须是名词）此句型中here/there用来唤起注意意思是“喂，注意了”。
如：Here comes Mary.→I can see Mary coming.玛丽来了。
There goes the bell.铃响了。
→I can hear the bell ringing.Here comes the bus.汽车来了。
There he comes.他来了。
这种句型不能用现在进行时。
here句中也可用系动词。
如：Here are some story books I want.→Here is what you asked for，or you are looking for.这就是我要的故事书。
（我找了好久）Here we are.This is the station.咱们到了，这就是火车站。
“Give me some paper.”“Here you are.”“给我点纸。
”“给你。
”3.then引起谓语为come，follow的句子。
如：Then came a new difficulty.然后产生了一个新的困难。
Then followed eight years of the Anti Japanese War.接着是八年抗战。
4.out，in，up,down，away之类的副词作状语放在句首，主语比较长，也就是说主语不能是很短的人称代词，谓语为不及物动词come，go，run,rush，etc。
句式为：副词＋vi.＋主语（必须是名词）。
如：Out rushed the tiger from among the bushes.老虎从灌木丛里冲了出来。
In came the rose fragrance through the windows.玫瑰花香透过窗户飘了进来。
5.介词短语作状语放在句首，谓语为不及物动词，主语比较长，也就是说主语不能是很短的人称代词。
句式为：介词短语＋vi.＋主语（必须是名词）。
如：In the middle of our school stands a high building.在学校中央有一座高楼。
6.表语放在句首，表语常为形容词、分词、副词、介词短语。
要求主语比较长，也就是说主语不能是很短的人称代词。
句式为：表语＋系动词＋主语（必须是名词）。
Gone are the days when the teachers were looked down upon.老师地位低下的年代一去不复返了。
On the both sides of the street are beautiful flowers.街道两旁有美丽的花。
South of city are two big lakes.城市的两边有两个大湖。
7.直接引语中间或后面，表示某人说这意思的插入语（特别是谓语较短时）。
“They must be in the fields now,”thought Xiao Lin.“他们准是下地了。
”小林想道。
“Help!Help!”cried the little girl.小姑娘叫道：“救命！救命！”如果主语不比谓语长，或是它后面有宾语，主语就仍然多放在前面。
“Take your seats，gentlemen,”Wilson shouted.威尔逊嚷道：“先生们坐好。
”“That man is a famous star,”Xiao Yang told me in a whisper.小杨低声告诉我说：“那个人是著名的电影明星。
”二、部分倒装1.“only＋副词/介词短语/状语从句”开头的句子。
如：Only then did I realize the importance of English.直到那时我才意识到英语的重要性。
Only in this way can you make progress in your English.只有通过这种方式你学英语才会取得进步。
注意：１）在only＋状语从句＋主句结构中，主句用倒装结构但从句用正常语序。
２）only修饰主语，不倒装。
Only Tom knows the answer.只有汤姆知道答案。
2.否定词（短语）开头的句子要用部分倒装。
表示否定的副词never，nor，neither,表示半否定意义的副词hardly，few，seldom，little，含有no和not 的词组by no means（决不），in no time（很快），at no time（在任何时候都不），（在任何情况下都不）not until，not only...but also，no sooner...than＝hardly...when/scarcely...when。
即“否定词＋助动词/情态动词＋主语＋其他”。
如：Never have I been in this city.我从没到过这座城市。
Little/Seldom do I watch TV.我很少看电视。
Not until I began to work did I realize how much time I had wasted.直到我参加了工作我才意识到我浪费了多少时间。
注意：1)关联词的搭配。
2)前一分句倒装，后一分句不倒装。
3.以so开头,用“so＋助动词/情态动词/系动词＋主语”表示前面叙述的情况也适合于另一个人或物，意为“也，同样，也如此”。
表示前面叙述的否定情况也适合于另一个人或物，用“neither/nor＋助动词/情态动词/系动词＋主语”。
Society has changed and so have the people in it.社会变了，人也变了。
注意:1)当so表示对前句内容的肯定、符合，或进一步强调前面所说的情况，或者赞同前面的说法时，应用自然语序。
意为“的确，正是”。
—Tom works hard.汤姆工作很卖力。
—So he does and so do you.的确如此，你也是。
2）倒装部分的助动词、情态动词、连系动词的时态和形式要与前句相一致。
If you don’t go，neither/nor shall I.（If you don’t go，I shall not go.）你不去，我也不去。
注意：表示前面的多种情况也适合于另一人或物，或者既有肯定又有否定情况或涉及到不同类型的动词时可用：It is the same with sth./sb.或So it is with sth./sb.句型。
She does well in English，but is poor in maths.So it is with Lucy.她英语学得好，但数学学的差，露茜也是如此。
4.由as引导让步状语从句要用部分倒装或前置。
句式为：表语/状语/动词原形＋as＋主语＋其他。
如：Clever as he is，he doesn’t study well.虽然他很聪明，但他学习不好。
Child as he is，he knows a lot.虽然他是个孩子，但他懂得不少事情。
Much as I like it，I won’t buy it.虽然我非常喜欢它，但我不买。
Try as she might，she failed.虽然她试过了，但还是失败了。
注意：表语前的名词无形容词修饰时冠词要省略5.在so...that从句中，如果so＋adj./adv.放在句首，其主句要倒装。
So loudly did he speak that everyone could hear him.他讲话声音足够大，以至于每个人都能听得见。
6.如果虚拟条件句的谓语含有were，should，were可以把if省略而将这三个词放于条件句主语前构成倒装。
If it hadn’t been for their help，we couldn’t have finished the work on time.＝Hadn’t it been for their help，we couldn’t have finished the work on time.要不是由于他们的帮助，我们不可能按时完成那项工作。
If there should be a flood，what would we do?＝Should there be a flood，what would we do?要是发了洪水，我们该怎么办呢？7.频度副词及短语often，always，now and then，many a time，every other day等放在句首时有时也倒装。
Many a time has he come to comfort me.他来安慰了我好多次。
Often did he warn them not to do so.他经常告诫他们不要那样去做。
8.某些表示祝愿句子也用倒状语序。
May you succeed.祝你成功！Long live the Communist Party of China!中国共产党万岁！第二部分强调句基本定义强调句(The Emphatic Pattern)是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。
通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。
英语常用的强调结构是"It is(was)+被强调部分(主语、宾语或状语)+who(that)..."。
一般说来,被强调部分指人时,用who;指事物时用that,但that也可以指人。
在美国英语中指事物时常用which来代替that。
常用句式1.陈述句的强调句型It is/was+被强调部分（通常是主语、宾语或状语）+that/who（当强调主语且主语指人）+其他部分。
