Unit 3 The World online Section Project原文呈现读文清障Researching on the InternetThe Internet is the fastest growing source of information in the world today. There are, however, some things to keep in mind when you use it to do research. Before you sit down at a computer terminal， read this brief guide to make sure that you use the Internet in the best way possible.Step one: choosing a search serviceLets start by looking at the two services you can choose between to assist you in your search: search engines and subjectdirectories. Both give you direct links, but the information is chosen and organized in different ways.keep in mind 谨记，牢记terminal/tmInl/n.终端，终端设备；终点 adj.末端的，末梢的注意in the best way possible中的way通常与介词in连用，possible作后置定语，修饰way。you can choose between是定语从句，修饰the two services。assist sb. in/with sth.在方面帮助某人directory/drektrI/n.目录；电话号码簿；公司名录因特网上作研究因特网是当今世界发展速度最快的信息来源。但是，当你使用因特网作研究时，有些事项是要谨记的。在你坐在计算机终端之前，阅读这一简要指南，以确保你尽可能以最好的方式使用因特网。步骤一：选择一种搜索服务让我们先看看能帮助你搜索的两种可选择的搜索服务：搜索引擎和主题目录。这两者都能给你直接的链接，但是两者对信息的选择和组织方式不一样。Search enginesSearch engines are a type of computer program. The links that you get are not classified by subject. These engines search the Internet for you based on the key words you type in, and choose web pages for you which contain the words you ask for. The contents they search have not been evaluated. This means that the information has never been checked it could be reliable， true information or false information written by a person without qualifications or someone who does not have solid facts. The links you obtain from the search engines go to full articles or pages. This requires you to be patient as you have to read the information to decide whether it is linked to what you are researching. Examples of famous search engines are Google, Yahoo and Baidu. You can also go to the www. thesearchenginelist. com website and check their list of search engines.Subject directoriesSubject directories are built by humans. Someone has combed through pages and links and selected all those that are in the directory. The results of your search are divided into specific subjectcategories. You do not get the full pages to read. Instead, you get a bunch of titles of articles or pages and, sometimes, a short summary of the information they contain. You need to decide whether the information is useful to you on that basis. Most often, the information in subject directories has been evaluated, and someone has decided that the information is relevant and correct. Being relevant and correct， though, does not equal being up to date.search enginen(因特网)搜索引擎that you get 是定语从句，修饰先行词the links。classify/klsIfaI/vt.分类，归类classify by 按照进行归类type/taIp/vt.(用计算机或打字机)打字web/web/n.网状物，网络web pagen网页which引导定语从句，修饰web pages；其中you ask for也是定语从句，修饰the words，引导词that/which被省略了。evaluate v评估，评价reliable adj.可信的，可靠的false adj.虚假的，伪造的；人造的，错误的qualification/kwlIfIkeIn/n.资格，资历without qualifications 没有资格solid本意为“固体(的)”，此处引申为“可靠的”。you obtain from .是定语从句，修饰the links。require sb. to do sth.要求某人做某事be linked to 连接到comb/km/vt.仔细搜索；梳理(头发) n梳子comb (through) sth. (for) 仔细搜寻that 引导定语从句，修饰those，that在从句中作主语。specific/spsIfIk/adj.具体的，明确的；特定的；独特的category/ktgrI/n.类别，种类bunch/bnt/n.串，束a bunch of 一串，一束；大量whether引导宾语从句。on that basis 在那个基础之上on the basis of 以为基础relevant/relvnt/adj.紧密相关的，切题的；有价值的be relevant to与相关联，与切题动名词短语作主语，谓语动词用单数形式。搜索引擎搜索引擎是一种电脑程序。你获得的链接并没有根据主题分类。搜索引擎根据你输入的关键词在网络上为你进行搜索，并选择包含你所寻找的词语的网页。它们搜索的内容并没有经过评估。这意味着(搜索到的)信息从未被核实过它可能是可靠、真实的信息，也可能是由没有资历的人或没有掌握确凿事实根据的人撰写的虚假信息。你从搜索引擎获得的链接指向完整的文章或页面。这就需要你有耐心，因为你必须阅读这些信息，然后判断它是否与你所作的研究有关。有名的搜索引擎有谷歌、雅虎和百度。你也可以进入网站查看所提供的搜索引擎列表。主题目录主题目录是由人建立的。有人已将页面和链接整个搜索了一遍，选出了所有那些列在目录中的内容。你搜索的结果会被分成特定的主题范围。你阅读的并非完整的页面。相反，你看到的只是很多文章的标题或页面的标题，有时候是它们所含信息的概要。在此基础上，你得判定这些信息对你是否有用。大多数情况下，主题目录里的信息是经过评估的，有人已经判定这些信息是相关的和正确的，不过，相关的和正确的信息并不等同于最新的信息。Step two: searching forinformationThere are several things to take into consideration when you are searching.1Information gets old. Just as you might look at when a book was published, you must also check the dates of the websites you find. Many websites will say, at the bottom of the page, the date when they were last updated. Do not use information that is too old.2People put information on the Internet. Usually, people try ot put correct information on the Internet, but not every personbothers to read over their own writing and make corrections. As a general rule， check the source of the information you find. Personal web pages are not recommended for doing research. Government pages or pages managed by organizations and companies you trust are much better. If you are not sure about the information you find, consult other web pages to confirm it.3The way you type your key words makes a difference. If you use the plus symbol ， it means the same as the word and. You can search for birdsparrow and the results of your search will only be pages that have both the words bird and sparrow in them. A minus symbol means the same as not， so if you want to learn about birds but you do not want any information about sparrows， you could type birdsparrow. Then your results will be all the pages that have the word bird， but not ones that have the word sparrow. If you type bird OR sparrow， then your results will be web pages that have information about birds or sparrows.search for 搜查，搜索take . into consideration把考虑在内at the bottom of 在的底部not every person是部分否定，表示“不是每个人都”。bother/b(r)/vi.&vt.花费时间、精力(做某事)；打扰，给某人造成麻烦bother to do sth. 费心做某事correction/krekn/n.改正，纠正，修正make corrections修改as a general rule 一般来说，通常说来generally speaking 一般说来recommend sth. for sth./sb.为某事/某人推荐某物过去分词短语managed by .作后置定语，修饰pages。consult v查阅；咨询，请教，(与某人)商议consult a dictionary 查词典consult (with) sb. about sth. 咨询某人某事；与某人商议某事you type your key words是定语从句，修饰the way。引导词that或in which已被省略。make a difference 有影响，起(重要)作用plus/pls/n.加号；优势，长处 prep.加；以及，和adj.零度以上的minus/maIns/n.减号；负号；缺点 prep.减；没有，缺乏 adj.零度以下的；负数的sparrow/spr/n.麻雀两个that都引导定语从句，分别修饰the pages和ones。ones作为替代词，代替前面出现的pages。步骤二：搜索信息当你在搜索信息时，有几件事要考虑：1.信息会过时。正如你可能会留意书的出版时间一样，你也必须检查你所找到的网站的日期。很多网站会在页面的底部标明他们上次更新的日期。不要使用过于陈旧的信息。2.是人将信息放在因特网上的。通常，人们试图把正确的信息放在因特网上，但并不是每个人都会费心校对他们所写的东西并作修改。作为一项常规的做法，核查你所找到的信息的来源。不建议将个人网页作研究之用。政府网页或你信得过的机构和公司的网页要好得多。如果你对找到的信息感到不确定，查阅其他网页来确认它。3.输入关键词的方式很重要。如果你使用符号“”，它的意思就与“和”一样。你可以键入“鸟麻雀”，你搜索的结果就是所有含有“鸟”和“麻雀”的页面。符号“”的意思是“不是”，所以，假如你想了解鸟类但不需要任何麻雀的信息，就键入“鸟麻雀”，那么所有显示出来的页面就会都含有“鸟”，但不包括“麻雀”。如果键入“鸟OR麻雀”，那么显示的网页既可能是关于鸟的，也可能是关于麻雀的。Step three: using your informationRemember that someone wrote the information you have found. This means those words belong to them. To copy the words just as you found them is not only cheating, but also illegal. Write an outline of the information you have found. Then write your report, using your own words and making your own decisions about what it means. When you are finished, you should always acknowledge where you got your data by attaching a list of the websites you got your information from. This way, a teacher can check them, and an interested friend can also read what you read.Follow these tips, and your time spent doing research on the Internet will be much more worthwhile.
