( Cac ban giai thich giup minh nhe) We've all heard the incredible dot-com success stories about Internet start-ups that became billiondollar companies almost overnight. Companies like e-Bay, PayPal, YouTube, and Google turned a lucky few into instant millionaires. But what about the so-called "dot-bombs, " the companies that didn't make it? Who were they, and what did they do wrong? Webvancom was an online grocery store that was founded in the late 1990s and went bankrupt in 2001 . On Webvancom, a user could order groceries and have them delivered whenever they wanted. Sounds like a great idea, right? So why did it fail? Like some of its fellow Internet failures, Webvancom moved much too fast. Within a year and a half, Webvan was available in eight cities and had plans to enter over a dozen more. Perhaps counting on a huge number of future users, Webvan spent over $1 billion on warehouses and supplies before it had become profitable. But the company didn't attract the number of users it needed and soon closed its doors. Another mistake shared by some dot-bombs is spending too much money on advertising and losing sight of the company's real goals. For example, the company Petscom focused a great deal of its energy and funding on commercials featuring a loveable sock puppet. The puppet became extremely popular with consumers, and the company spent millions of dollars on advertising. But the start-up's actual service, selling and delivering pet supplies, never became popular enough with consumers to justify all the money that was spent on promotion. The downfall of some other dot-bombs was focusing on cutting-edge technology more than user needs. This was one of the factors leading to the failure of the British start-up needs. This start-up was created to sell fashion online to consumers around the world. However, the website was difficult to navigate, and it used technology that required a lot of bandwidth to operate at a time when most people were using slow dial-up connections. . 1.Which would be the suitable title for the passage? A. Successful Internet starts-ups B. The foundation of dot-bombs C. Dot-bombs -their recipes for failure D. The failure of dot-coms 2. The word "them" in paragraph 2 refers to A. companies B. groceries C. users D. grocery stores 3. What is the reason why Webvancom failed, as stated in the passage? A. It spent too little on warehouse and supplies. B. It acted too rashly C. It attracted a large number of customers D. It had to borrow from banks to buy supplies 4. The word "cutting-edge" in paragraph 3 is closest in meaning to A. dangerous B. sharp C. blunt D. advanced 5.Which of the following is NOT mentioned in the passage? A. YouTube is one of the incredible dot-com success stories B. Some dot-bombs paid too much attention on commercials C. Petscom ultimately forgot its initial business goal D. Webvan never had a plan to expand into new markets
