eBay eBay is a global phenomenon-the world’s largest garage sale, online shopping center, ear dealer and auction site with 147 million registered users in 30 countries as of March 2005. You can find everything from encyclopedias to olives to snow boots to stereos to airplanes for sale. And if you stumble on it before the eBay overseers do, you might even find a human kidney or a virtual date. eBay Basics eBay is, first and foremost, an online auction site. You can browse through categories like Antiques, Boats, Clothing & Accessories, Computers & Networking, Jewelry & Watches and Video Games. When you see something you like, you click on the auction title and view the details, including pictures, descriptions, payment options and shipping information. If you place a bid on an item, you enter a contractual agreement to buy it if you win the auction. All auctions have minimum starting bids, and some have a reserve price-a secret minimum amount the seller is willing to accept for the item. If the bidding doesn’t reach the reserve price, the seller doesn’t have to part with the item. In addition to auctions, you can find tons of fixed-price items on eBay that make shopping there just like shopping at any other online marketplace. You see what you like, you buy it, you pay for it and you wait for it to arrive at your door. You can pay for an item on eBay using a variety of methods, including money order, cashier’s check, cash, personal check and electronic payment services like PayPal and BidPay. It’s up to each seller to decide which payment methods he’ll accept. Just as you can buy almost anything on eBay, you can sell almost anything, too. Using a simple listing process, you can put all of the junk in your basement up for sale to the highest bidder. When you sell an item on eBay, you pay listing fees and turn over a percentage of the final sale price to eBay. Once you register (for free) with eBay, you can access all of your eBay buying and selling activities in a single location called "My eBay." eBay Infrastructure A series of service disruptions in 1999 caused real problems for eBay’s business. Over the course of three days, overloaded servers intermittently shut down, meaning users couldn’t check auctions, place bids or complete transactions during that period. Buyers, sellers and eBay were, very unhappy, and a complete restructuring of eBay’s technological architecture followed. In 1999, eBay was one massive database server and a few separate systems running the search function. In 2005, eBay is about 200 database servers and 20 search servers. The architecture is a type of grid computing that allows for both error correction and growth. With the exception of the search function, everything about eBay can actually run on approximately 50 servers-Web servers, application servers and data-storage systems. Each server has between 6 and 12 microprocessors. These 50 or so servers run separately, but they talk to each other, so everybody knows if there is a problem somewhere, eBay can simply add servers to the grid as the need arises. While the majority of the site can run on 50 servers, eBay has four times that. The 200 servers are housed in sets of 50 in four locations, all in the United States. When you’re using eBay, you may be talking to any one of those locations at any time--they all store the same data. If one of the systems crashes, there are three others to pick up the slack. When you’re on the eBay Web site and you click on a listing for a Persian rug, your com-puter talks to Web servers, which talk to application servers, which pull data from storage servers so you can find out what the latest bid price is and how much time is left in the auction, eBay has local partners in many countries who deliver eBay’s static data to cut down on download time, and there are monitoring systems in 45 cities around the world that constantly scan for problems in the network. Using eBay: Security In order to make buyers feel safer when making purchases on eBay, all tangible (有形的) items are automatically insured for 200. A recipe that was supposed to be delivered to you via e-mail is not considered a tangible item. But if you purchased a set of speakers that never arrived, and you go through the dispute process and eBay determines you were defrauded (欺骗), you can get your money back up to 200. Buyer Fraud Buyer fraud is typically less damaging than seller fraud. The most common type of fraud a buyer can commit is simply not paying for an item. Sellers can deal with non-paying bidders by filing an Unpaid Item dispute, eBay will then attempt to contact the buyer and get her to pay. If she does not respond to eBay’s attempts after eight days, the seller is reimbursed (赔偿)for eBay’s cut of the final sale price and can relist the item for free. If the buyer does respond, the dispute can end in one of three ways: The buyer decides to pay, and everybody’s happy. The buyer and the seller decide together to abandon the transaction, the seller gets reimbursed for the final-value fee and relists the item for free, and everybody’s happy. The seller decides not to deal with the buyer, the buyer gets an unpaid-item strike against her, and the seller gets reimbursed for the final-value fee and relists the item for free. In the end, the damage to the seller is relatively small. Another type of buyer fraud occurs when a buyer sends false payment. In most cases, this is in the form of a bounced check, and the seller finds out about it before shipping the item. Bounced checks are as common on eBay as they are in the rest of the world, and many sellers choose not to accept personal checks for this reason. Seller Fraud Seller fraud is what most people think about when they worry about using eBay. There are two main ways in which a buyer can be defrauded by a seller. The item the buyer purchased is dramatically different from how it was described in the listing; or the item simply never arrives. One thing to keep in mind when you think you’ve been defrauded is that miscommunication is common on eBay. For instance, if you didn’t read every word of the auction listing for your item, you may have missed the part that said the seller would be out of town for three weeks and wouldn’t be able to ship the item until she returned. This could be why you don’t have your item and the seller isn’t answering your e-mails. Also, e-mail is not the most straightforward form of communication. If your item hasn’t arrived after two weeks, and you’ve e-mailed the seller but haven’t heard back, it’s a good idea to check your junk mail folder. Your seller may have sent a response e-mail that just never made it to your inbox. If there’s nothing from the seller in your junk folder, you can request that eBay reveal your seller’s phone number so you can give him a call and see what’s going on. If you don’t get an answer to your phone call (or if your seller lives in another country and it would cost too much money to call), your next step is to start the dispute process. When a buyer believes he has been defrauded, he can file a complaint, and eBay will work to solve the problem. When you file a complaint in eBay’s "Item Not Received or Significantly Not as Described" system, eBay will act as middleman between you and your seller to try to settle the dispute. If that fails, you can file a claim to get reimbursed for your purchase.At present, each of eBay’s server is equipped with ______ microprocessors. A．200B．about 50C．6 to 12D．20

Below are some tips for women traveling alone.Exercise hotel safetyThere are many ways you can make a solo stay at a hotel safer. At cheek-in, you might consider asking for a room near the elevator so you won't need to walk down long, potentially ill-lit hallways to reach your room. When filling out guest registration forms， consider using your first initial instead of your name, and skip the " Mrs/Miss/Mr" check box. Additionally, make sure the clerk writes down your room number instead of saying it out loud. This will prevent anyone nearby from knowing where to find you later.Arrive during the dayArrive in new cities during the day. Areas around bus and train stations can be scary and/or deserted, and small towns tend to shut down early. Veteran solo traveler Mara Rothman of San Francisco notes that plenty of beautiful towns can appear mysterious at night, and locals who are genuinely trying to help you can appear unnecessarily threatening. Arriving during the day means you'll be able to find a place to stay and get to know where you are before dark.Keep your documents safe If you choose to wear a money belt, use it for storage and not as a purse. Constantly reaching under your shirt for money draws attention to it, and tends to defeat the purpose. Instead，keep your passport, extra stores of money, and other important documents well hidden, and use a bag or purse for carrying daily spending money.Dress appropriatelyTo avoid attracting unwanted attention, dress as conservatively as the women you see around you. This doesn't necessarily mean wearing the traditional dress, as that can sometimes have the opposite result. A good rule of thumb is to dress modestly. Think knee-length or longer skirts. Bare arms, shoulders, and legs are considered risked in some countries, so do the research before you go and once you're there. Note which body parts the local women cover and do the same.Know when to make friends Traveling alone doesn't always mean being alone. There are plenty of situations in which seeking out company can make for a safer and more enjoyable experience. Smaller hotels and hostels are great places to find like- minded travelers to explore new places with. In some countries, there are women-only sections in trains and women's waiting rooms at train stations. Sticking close to families on public transportation and in unfamiliar public markets and bazaars is another technique some women use.Show confidence to a great extentWhether you're on a street at home or 7, 000 miles away, walking confidently and with direction is an effective technique for deterring unwanted attention, since appearing lost or confused can make you weak and easily damaged. If you are lost，walk into a shop or restaurant and ask for directions there. Try to avoid obviously looking at maps while you're in the street. Study your route before you go, or find one of those wallet-sized maps that you can carefully palm and refer to secretly.Use common senseUsing common sense is perhaps the single best tip for staying safe and having a good time while you，re traveling alone. This category includes the usual recommendations: don't walk around late at night , don't drink with strange men，don't ride in empty compartments on trains, don't compromise safety to save a few bucks on a hotel or transportation, and know how to use a pay phone.1.

When it came to role models，Diana Ortiz said her mother，Marcia Dominguez，was the "hero". Ms. Dominguez came to the United States from Cuba in 1979. She went to college and got a job as a social worker - all the while raising three children in America mostly on her own. "It was always school first，" Diana said， "My mom had us in a straight line. If we got out of line，she corrected us. She was a perfect woman. She was beautiful，she had the education and she had everything - but the illness took over. When I was 11， it frightened me to see how quickly my mother's health was ruined by cancer. A week before I turned 14， my mother died at age 50. I had tried to prepare myself， but on the first morning I woke up without my mother， the sense of loss was painful." Diana had not seen her father for five years，who refused to provide for her. Diana then entered the city's foster care system. She has spent about four years in foster homes. Despite Diana's hard teenage years， the values her mother had planted in her mind inspired her to go after higher education. Since August 2010， she has been a fulltime student majoring in law. A public organization offers her tuition but she has part-time jobs to help people like her and earn more life experience. Her goal is a job in the Federal Bureau of Investigation. For now， Diana works 20 hours a week as a cashier at Marshalls， earning D|S7.25 an hour. In November， she moved into her own public housing studio apartment on the Lower East Side. She pays D|S236 a month in rent. Although she is out of foster care，Diana has been speaking at workshops for foster youths. She emphasizes that nothing should get in the way of their success， not the trials of their lives or what they may have lost. "I tell the young who have the similar experience like me，'Why are you going to let what happened to you affect you in the long run？'" Diana said， "'Why are you going to sit there and feel sorry for yourself？You're wasting precious time.' It is a message my mother would approve of. My mom taught me that everything is not given to you. You have to go out and get it."（1）Which of the following words can be used to describe Ms. Dominguez？ ____ A．Learned， independent and strict.B．Positive， simple and graceful.C．Hardworking， dependent and tough.D．Kind， determined and lonely.（2）How did Diana grow up after her mother passed away？ ____ A．She was provided for by a law institute.B．She depended on foster care system.C．She relied upon the people like her.D．She supported herself by doing part-time work.（3）What made Diana go on with her education despite there are so many difficulties？ ____ A．The sense of loss from her mother's death.B．The eagerness to achieve success.C．The deep influence of her mother's values.D．The wish to win prizes to please her mother.（4）With provided tuition， Diana still works after school because she knows ____ .A．success comes with her own struggle and effortsB．rich experience helps her find better jobsC．her tuition will be increased sharplyD．nobody is perfect in the world
