2010年浙江省金华市中考科学试题
AbstractThe ABSTRACT is to be in fully-justified italicized text, at the top of the left-hand column, below the author and affiliation information. Use the word “Abstract” as the title, in 12-point Times, boldface type, centered relative to the column, initially capitalized. The abstract is to be in 10-point, single-spaced type. The abstract may be up to 3 inches (7.62 cm) long. Leave two blank lines after the Abstract, then begin the main text.1.IntroductionPlease follow the steps outlined below when submitting your manuscript to the IEEE Computer Society Press. This style guide now has several important modifications (for example, you are no longer warned against the use of sellotape to attach your artwork to the paper), so all authors should read this new version.nguageAll manuscripts must be in English.1.2.Dual submissionBy submitting a manuscript to CVPR, the authors assert that it has not been previously published in substantially similar form. Furthermore, no paper which contains significant overlap with the contributions of this paper either has been or will be submitted during the CVPR 2011 review period to either a journal or any conference (including CVPR 2011) or any workshop (including CVPR2011 workshosp).Note that this is consistent with CVPR2010 but a strengthening from the policy of some previous CVPRs}. Papers violating this condition will be rejected and a list of violating authors may be included in the proceedings.If there are any papers that may appear to the reviewers to violate this condition, then it is your responsibility to (1) cite these papers (preserving anonymity as described in Section 1.6 below), (2) argue in the body of your paper why your CVPR paper is nontrivially different from these concurrent submissions, and (3) include anonymized, versions of those papers in the supplemental material.1.3.Paper lengthConsult the call for papers for page-length limits. Overlength papers will simply not be reviewed. This includes papers where the margins and formatting are deemed to have been significantly altered from those laid down by this style guide. Note that this LATEX guide already sets figure captions and references in a smaller font. The reason such papers will not be reviewed is that there is no provision for supervised revisions of manuscripts. The reviewing process cannot determine the suitability of the paper for presentation in eight pages if it is reviewed in eleven.1.4.The rulerThe LATEX style defines a printed ruler which should be present in the version submitted for review. The ruler is provided in order that reviewers may comment on particular lines in the paper without circumlocution. If you are preparing a document using a non-LATEX document preparation system, please arrange for an equivalent ruler to appear on the final output pages. The presence or absence of the ruler should not change the appearance of any other content on the page. The camera ready copy should not contain a ruler. (LATEX users may uncomment the \cvprfinalcopy command in the document preamble.) Reviewers: note that the ruler measurements do not align well with lines in the paper—this turns out to be very difficult to do well when the paper contains many figures and equations, and, when done, looks ugly. Just use fractional references (e.g. this line is 189.5), although in most cases one would expect that the approximate location will be adequate.1.5.MathematicsPlease number all of your sections and displayed equations. It is important for readers to be able to refer toMicrosoft Word Author Guidelines for CVPR ProceedingsFirst AuthorInstitution1 Institution1 address firstauthor@Second AuthorInstitution2First line of institution2 address /_secondany particular equation. Jus t because you didn’t refer to it in the text doesn’t mean some future reader might not need to refer to it. It is cumbersome to have to use circumlocutions like ―the equation second from the top of page 3 column 1‖. (Note that the ruler will not be present in the final copy, so is not an alternative to equation numbers). All authors will benefit from reading Mermin’s description of how to write mathematics:/doc/mermin.pdf. Every equation should be numbered, even if you don't refer to it!1.6.Blind reviewMany authors misunderstand the concept of anonymizing for blind review. Blind review does not mean that one must remove citations to one’s own work—in fact it is oftenimpossible to review a paper unless the previous citations are known and available.Blind review means that you do not use the words ―my‖ or ―our‖ when citing previous work. That is all. (But see below for techreports)Saying ―this builds on the work of Lucy Smith [1]‖ does not say that you are Lucy Smith, it says that you are building on her work. If you are Smith and Jones, do not say ―as we show in [7]‖, say ―as Smith and Jones show in [7]‖ and at the end of the paper, include reference 7 as you would any other cited work.An example of a bad paper:An analysis of the frobnicatable foo filter.In this paper we present a performance analysisof our previous paper [1], and show it to be inferiorto all previously known methods. Why theprevious paper was accepted without this analysisis beyond me.[1] Removed for blind reviewAn example of an excellent paper:An analysis of the frobnicatable foo filter.In this paper we present a performance analysis ofthe paper of Smith et al. [1], and show it to beinferior to all previously known methods. Why theprevious paper was accepted without this analysisis beyond me.[1] Smith, L and Jones, C. ―The frobnicatablefoo filter, a fundamental contribution to humanknowledge‖. Nature 381(12), 1-213.If you are making a submission to another conference at the same time, which covers similar or overlapping material, you may need to refer to that submission in order to explain the differences, just as you would if you had previously published related work. In such cases, include the anonymized parallel submission [4] as additional material and cite it as[1] Authors. ―The frobnicatable foo filter‖, ECCV 2006 Submission ID 324, Supplied as additional material eccv06.pdf.Finally, you may feel you need to tell the reader that more details can be found elsewhere, and refer them to a technical report. For conference submissions, the paper must stand on its own, and not require the reviewer to go to a techreport for further details. Thus, you may say in the body of the paper ―further details may be found in [5]‖. Then submit the techreport as additional material. Again, you may not assume the reviewers will read this material. Sometimes your paper is about a problem which you tested using a tool which is widely known to be restricted to a single institution. For example, let’s say it’s 1969, you have solved a key problem on the Apollo lander, and you believe that the CVPR70 audience would like to hear about your solution. The work is a development of your celebrated 1968 paper entitled ‖Zero-g frobnication: How being the only people in the world with access to the Apollo lander source code makes us a wow at parties‖, by Zeus et al. You can handle this paper like any other. Don’t write ―We show how to improve our previous work [Anonymous, 1968]. This time we tested the algorithm on a lunar lander [name of lander removed for blind review]‖. That would be silly, and would immediately identify the authors. Instead write the following:We describe a system for zero-g frobnication. This system is new because it handles the following cases: A, B. Previous systems [Zeus et al. 1968] didn’t handle case B properly. Ours handles it by including a foo term in the bar integral....The proposed system was integrated with the Apollo lunar lander, and went all the way to the moon, don’t you know. It displayed the following behaviours which show how well we solved cases A and B: ...Figure 1: Example of a figure with caption. Captions are set in roman, 9 point. Use a Drawing area to make space for figures.As you can see, the above text follows standard scientific convention, reads better than the first version, and does not explicitly name you as the authors. A reviewer might think it likely that the new paper was written by Zeus et al, but cannot make any decision based on that guess. He or she would have to be sure that no other authors could have been contracted to solve problem B.1.7. MiscellaneousWhen citing a multi-author paper, you may save space byusing ―et alia ‖, shortened to ―et al .‖ (not ―et. al.‖ as ―et ‖ is a complete word.) However, use it only when there are three or more authors. Thus, the following is correct:―Frobnication h as been trendy lately. It was introduced by Alpher [3], and subsequently developed by Alpher and Fotheringham-Smythe [1], and Alpher et al. [2].‖This is incorrect: ―... subsequently developed by Alpher et al. [1] ...‖ because reference [1] has just two a uthors. If you use the \etal macro provided, then you need not worry about double periods when used at the end of a sentence as in Alpher et al.For this citation style, keep multiple citations in numerical (not chronological) order, so prefer [1, 3, 4] to [3, 1, 4].2. Formatting your paperAll text must be in a two-column format. The total allowable width of the text area is 76inches (17.5 cm) wide by 878inches (22.54 cm) high. Columns are to be 31/4 inches (8.25 cm) wide, with a 5/16 inch (0.8 cm) space between them. The main title (on the first page) should begin 1.0 inch (2.54 cm) from the top edge of the page. The second and following pages should begin 1.0 inch (2.54 cm) from the top edge. On all pages, the bottom margin should be 811inches (2.86 cm) from the bottom edge of the page for 8.5 × 11-inch paper; for A4 paper, approximately 851inches(4.13 cm) from the bottom edge of the page.2.1. Margins and page numberingAll printed material, including text, illustrations, and charts, must be kept within a print area 876 inches (17.5 cm) wide by 878inches (22.54 cm) high. 2.2. Type-style and fontsWherever Times is specified, Times Roman may also be used. If neither is available on your word processor, please use the font closest in appearance to Times to which you have access.MAIN TITLE. Center the title 1-3/8 inches (3.49 cm) from the top edge of the first page. The title should be in Times 14-point, boldface type. Capitalize the first letter of nouns, pronouns, verbs, adjectives, and adverbs; do not capitalize articles, coordinate conjunctions, or prepositions (unless the title begins with such a word). Leave two blank lines after the title.AUTHOR NAME(s) and AFFILIATION(s) are to be centered beneath the title and printed in Times 12-point, non-boldface type. This information is to be followed by two blank lines.The ABSTRACT and MAIN TEXT are to be in a twocolumn format.MAIN TEXT. Type main text in 10-point Times, singlespaced. Do NOT use double-spacing. All paragraphs should be indented 1 pica (approx. 1/6 inch or 0.422 cm). Make sure your text is fully justified —that is, flush left and flush right. Please do not place any additional blank lines between paragraphs.Figure and table captions should be 9-point Roman type as in Figures 1 and 2. Short captions should be centred. Callouts should be 9-point Helvetica, non-boldface type. Initially capitalize only the first word of section titles and first-, second-, and third-order headings.FIRST-ORDER HEADINGS. (For example,1.Figure 2: Short captions should be centred.Introduction) should be Times 12-point boldface, initially capitalized, flush left, with one blank line before, and one blank line after.SECOND-ORDER HEADINGS. Should be Times 11-point boldface, initially capitalized, flush left, with one blank line before, and one after. If you require a third-order heading (we discourage it), use 10-point Times, boldface, initially capitalized, flush left, preceded by one blank line, followed by a period and your text on the same line.2.3.FootnotesPlease use footnotes1 sparingly. Indeed, try to avoid footnotes altogether and include necessary peripheral observations in the text (within parentheses, if you prefer, as in this sentence). If you wish to use a footnote, place it at the bottom of the column on the page on which it is referenced. Use Times 8-point type, single-spaced.2.4.ReferencesList and number all bibliographical references in 9-point Times, single-spaced, at the end of your paper. When referenced in the text, enclose the citation number in square brackets, for example [4]. Where appropriate, include the name(s) of editors of referenced books.2.5.Illustrations, graphs, and photographsAll graphics should be centered. Please ensure that any point you wish to make is resolvable in a printed copy of the paper. Resize fonts in figures to match the font in the body text, and choose line widths which render effectively in print. Many readers (and reviewers), even of an electronic copy, will choose to print your paper in order to read it. You cannot insist that they do otherwise, and therefore must not assume that they can zoom in to see tiny details on a graphic. When placing figures in LATEX, it’s almost always best to use \includegraphics, and to specify the figure width as a multiple of the line width as in the example below\usepackage[dvips]{graphicx} ...\includegraphics[width=0.8\linewidth]{myfile.eps}2.6.ColorColor is valuable, and will be visible to readers of the electronic copy. However ensure that, when printed on a monochrome printer, no important information is lost by the conversion to grayscale.1 This is what a footnote looks like. It often distracts the reader from the main flow of the argument. 3.Final copyYou must include your signed IEEE copyright release form when you submit your finished paper. We MUST have this form before your paper can be published in the proceedings. Please direct any questions to the production editor in charge of these proceedings at the IEEE Computer Society Press: Phone (714) 821-8380, or Fax (714) 761-1784.References[1] A. Alpher, , and J.

2010年浙江省金华市中考数学试卷(全解全析)
2010年浙江省金华市中考数学试卷(全解全析)一、选择题(共10小题,每小题3分,满分30分)1、(2010•金华)在﹣3,﹣√3,﹣1,0这四个实数中,最大的是()A、﹣3B、﹣√3C、﹣1D、0考点:实数大小比较。
分析:由于正数、0大于所有负数,根据这个法则即可比较四个数的大小.解答:解:∵|﹣3|=3,|﹣√3|=√3,|﹣1|=1,3>√3>1,∴﹣3<﹣√3<﹣1,又因为0大于一切负数,所以﹣3<﹣√3<﹣1<0.故选D.点评:此题主要考查了实数的大小的比较,比较两个实数的大小,可以采用作差法、取近似值法等.实数大小比较法则:(1)正数大于0,0大于负数,正数大于负数;(2)两个负数,绝对值大的反而小.2、(2010•金华)据报道,5月28日参观2010上海世博会的人数达35.6万,用科学记数法表示数35.6万是()A、3.56×101B、3.56×104C、3.56×105D、35.6×104考点:科学记数法—表示较大的数。
专题:应用题。
分析:应先把35.6万整理为用个表示的数,科学记数法的一般形式为:a×10n,在本题中a 为3.56,10的指数为整数数位减1.解答:解:35.6万=356 000=3.56×105.故选C.点评:将一个绝对值较大的数写成科学记数法a×10n的形式时,其中1≤|a|<10,n为比整数位数少1的数.3、(2010•金华)在平面直角坐标系中,点P(﹣1,3)位于()A、第一象限B、第二象限C、第三象限D、第四象限考点:点的坐标。
分析:应先判断出所求点的横纵坐标的符号,进而判断点所在的象限.解答:解:因为点P(﹣1,3)的横坐标是负数,纵坐标是正数,所以点P在平面直角坐标系的第二象限.故选B.点评:解决本题的关键是掌握好四个象限的点的坐标的符号特征:第一象限正正,第二象限负正,第三象限负负,第四象限正负.4、(2010•金华)图中几何体的主视图是( )A 、B 、C 、D 、考点:简单组合体的三视图。

4. 这个寓言故事告诉我们一个怎样的道理?(二)《谁与我同行》上初中时,学校每周总有二三晚的补习课。
家中离学校有三里来路地,白天不觉怎样,三蹦两跳便到了学校,夜晚就悚然了。
过一片稻田,翻一座山岭,而过岭是极惧怕的。
一条窄窄的山道,铺着青石,是乡村独轮车行的路。
两旁是过人的小树林,风一吹来,飒飒作响。
间或林子里有夜莺和爬行动物鸣叫,全身毛孔大张,一身冷汗。
有月亮时,从密密的枝桠间透出些淡淡的光两来,洒在青石路上,行来可稍见轻松些;若遇伸手不见五指的夜晚,心口便如兜着一只小兔。
这时就想起母亲的话来,将头顶的毛发尽力往上梳,露出亮亮的额头来。
母亲说,年轻人额头有团火,能驱妖捉魔。
走夜路最怕的是碰上“鬼”这东西,,尽管谁也没见过。
总之,晚上补习归来,见四周漆黑,便无端想起了“鬼”来。
父亲见我害怕,便说:胆是锻炼出来的,你应该时时想到你是男子汉。
一天晚补习归来,刚上山岭,便见前面几时米远的地方有个火把在移动。
我高兴极了,心里也不再有惧怕。
我加快步伐,想赶上那火把,结伴过岭。
谁知我的步子加快时,那火把移动的速度也加快了。
我的心顿时一阵惊跳,莫不是碰上老人们说的“鬼火”!夏天纳凉,老人们常说鬼的故事,都说荒郊野外有鬼火出没。
一时间,我仿佛肩上压有千斤重担,两腿发软,寸步难移。
想到了父亲的话,你是男子汉,我多少鼓了鼓勇气,艰难地一步步朝前走去。
