1、大学英语四级模拟试卷 248及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a composition entitled Complaint to the Manager. You should write at least 120 words following the outline given below: 假设你叫王丽,是某大学学生。暑假期间你和你的同学由 旅行社安排到五夷山旅游。你们所得到的服务,如导游、住宿条件以及饮食等均与广告不符。为此,你很恼火,
2、特写信给旅行社经理就以上情况进行投诉并希望该旅行社能够返还部分费用并改进服务。 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark: Y (for YES) if the statement agre
3、es with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Searching the Web with Yahoo! Yahoo!, like the Web itself, is too large to be explored entirely link by lin
4、k. However, with over half a million sites divided into more than 25, 000 categories, Yahoo! is both browseable and searchable. Use these two features and you will almost always find something to match your interests. You can browse Yahoo! by simply clicking on the various categories listed on each
5、page. Search Yahoo! by entering a word (or, a few words) into the search box that appears on every page in the directory. Combine the two strategies and you can “browse and then search“ or “search and then browse“. Of course, a key question remains: “When should I search Yahoo!?“ You should search Y
6、ahoo! when you are looking for a website and you know its rifle. Example: Youre looking for People Magazine online. Instead of browsing through the News and Media category, finding Magazines, and then finding the People Magazine in the alphabetical list, just type “people magazine“ into any search b
7、ox (you dont need to capitalize the words and you dont need quotes). You should search Yahoo! when you are looking for a specific topic. Example: Youre planning a vacation to Australia. Remember that Yahoo! organizes sites into categories, Those categories are organized by topic. “Does Yahoo! have a
8、nything on the topic of Australian Travel?“ Search. Type in the words “australia travel“ (no quotes, no capitals) and see what happens. One of the first results is the category. Regional: Countries: Australia: Recreation and Sports: Travel. Is that the topic youre after? Yes. Click on it. And rememb
9、er: if you dont get results on your first search, modify it and try again: sometimes searching is more of an art than a science. You should search Yahoo! when you want to see where in Yahoo! a particular website is listed, Example: You love the computer game Myst Youre not really interested in Myst
10、itself, since youve already played it for 150 hours, but you are in the market for a similar product. Type “myst into any search box. Check the results. Click on the first category. This will take you to the Myst game category, deep within the Yahoo! Hierarchy (等级制度 ). Now, heres the cool part: Look
11、 at the title of the page “Top: Recreation: Games: Computer Games: Genres: Adventure: Titles: Myst“. All the words in that title are hyperlinks except for the last one (because you are already on the Myst page). Click on the next to last word, “Titles.“ Voila! There is a whole list of computer games
12、 in the same type as Myst. So, now you know when to search Yahoo!. How about reading a search results page? That can be a tricky task for the uninitiated. Once you get the hang of it, however, its not hard to master. Inside the Search Machine Yahoo! search looks for the following main things: Yahoo!
13、 categories, websites listed in Yahoo! Web pages indexed by Inktomi. For the first two of these, Yahoo! searches for matches in its database and then ranks the results in order of most relevant to least relevant. Some of the factors that affect relevancy are: The number of search words matched. The
14、more words matched the higher the rank. Exact word matches. These are ranked higher than approximate matches. Where in an entry the search words were found. A match in the title of a site is ranked higher than a match in the comments or URL. Getting Results The first set of results are Yahoo! catego
15、ries. Since categories are populated with Yahoo! sites, a Yahoo! category can yield hundreds or even thousands of relevant websites. Thats why we put them first. Of course, if no categories match your search terms, we send you straight to the Yahoo! sites. Yahoo! sites are listed with the categories
16、 that contain them, That way, you can click on the category above the site to get a whole bunch of related sites. This powerful search strategy is a great way to discover related websites. Again, if Yahoo! doesnt find any site matches for your search, it goes on to the next set of results. The third
17、 set of results, a full-text search of the entire Web, is provided by Inktomi, a Yahoo! partner. Inktomi uses whats called a search engine, and it specializes in indexing every single web page it can find. This gives it a lot of raw data. Search engines provide good results with very specific reques
18、ts, and often poor results with general requests. Even if Yahoo! has found categories and sites that match your search terms, you may still want to check out what Inktomi has to offer. If so, ail you have to do is click the “Web Pages“ text at the top of the search results page. The same goes for mo
19、ving back and forth between categories and sites. Just click on the text links. Know Your Options If youve taken a crack at a couple of searches, and you think youre ready to move up to the next level, check out the “Search Options“ page. Here, youll find a number of ways of expanding and/or refinin
20、g your searches. The settings on this page allow you to control: What type of document youre looking for, how your search words are related, the range of dates for the resulting sites, the number of results to show per page. The first setting asks you to select “Yahoo!“ or “Usenet“ or “Email Address
21、“. These options are useful if you are interested in searching beyond the Web. Usenet is a huge set of Internet discussion groups that covers everything from bottle caps to biotechnology. Its a useful place to search for information that may be too obscure (费解的 ) or short-lived to find a permanent h
22、ome on the Web. The last option allows you to target your search towards email addresses. The second setting allows you to establish how the words in your search are related. This option only matters if you are entering multiple words or a phrase. The main distinction is whether your search terms ar
23、e to be treated as one single phrase or a group of single words, and if its the latter, whether the search should only include results that match ail the terms. For the most part, these options are for fine-tuning, since Yahoo!s default (预设 ) settings should produce very good results without any hel
24、p. “I Found It!“ Now that youre armed with the basics of searching Yahoo!, youre ready to tackle the Web. What you look for is up to you. Of course, if youd like some practice, take a couple of minutes to track down these items: your hometown newspapers website if your name appears anywhere on the W
