But paying online is a tricky business for consumers who are too young to own credit cards.Most have to use a parent's card.They want a facility that allows them to spend money. That may come sooner than they think: new ways to take pocket money into cyber(網(wǎng)絡(luò)的)space are coming out rapidly on both sides of the Atlantic.If successful, these products can stimulate online sales. In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK.Most teenagers have access to the Internet at home or at school—88 percent in the US, 69 percent in the UK.According to the Jupiter Research, one in eight of those with Internet access has bought something online—mainly CDs and books. In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children.Pressing parents to spend online is less productive than pressing on the high street.They are more likely to ask “Why？” if you ask to spend some money online. One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK.Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as ￡20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account. 文章大意：現(xiàn)在很多英美青少年想用零花錢網(wǎng)購，購CD或衣服等，但如何實現(xiàn)網(wǎng)上便利付帳呢？ 1．What does the underlined word “They” in paragraph 1 refer to? A．Sellers. B．Buyers. C．Teenagers. D．Parents. 答案：C　細節(jié)理解題。從文章第一段“They like using the Internet...

A．More than half of the teenagers in the US and the UK have Internet access. B．Teenagers pay for goods online with their own credit cards. C．Most teenagers in the US and the UK have bought something online. D．Teenagers found it easier to persuade parents to buy online than in a shop. 答案：A　正誤判斷題。從第四段第二句中的“Most teenagers have access to the Internet at home or at school—88 percent in the US, 69 percent in the UK.”可知，在英國和美國超過了50%的青少年可以接觸到網(wǎng)絡(luò)，故答案選A項。 3．A new way to help teenagers shop online is to use______. A．a(chǎn) new machine B．special coins and notes C．prepaid cards D．pay-as-you-go mobile phones 答案：C　細節(jié)理解題。從最后一段中的第一句話可知，現(xiàn)在一個幫助青少年網(wǎng)絡(luò)購物的方法是用預(yù)付卡，所以答案選C。 4．What is the passage mainly about?

D．The arrival of cyber pocket money. 答案：D　主旨大意題。從全文可知，本文主要告訴我們?nèi)绾伪ＷC青少年上網(wǎng)購物的安全，以及就此所采用的新方法來保障他們的網(wǎng)絡(luò)零花錢，據(jù)此D項能較好地概括大意。 B The Internet has led to a huge increase in credit-card(信用卡)fraud. Your card information could even be for sale on an illegal website. Websites offering cheap goods and services should be regarded with care. Online shoppers who enter their credit-card information may never receive the goods they thought they bought. The thieves then go shopping with your card number—or sell the information over the Internet. Computer hackers(黑客) have broken down security systems, raising questions about the safety of cardholder's information. Several months ago, 25,000 customers of CD Universe, an online music retailer(零售商), were not lucky. Their names, addresses and credit-card numbers were posted on a website，after the retailer refused to pay $ 157,828 to get back the information. Credit-card firms are now fighting against online fraud. Mastercard is working on plans for Web—only credit card, with a lower credit limit. The card could be used only for shopping online. However, there are a few simple steps you can take to keep from being cheated. Ask about your credit-card firm's online rules: Under British law, cardhohlers have to pay the first $ 78 of any fraudulent spending. And shop only at secure sites. Send your credit-card information only if the website offers advanced secure system. If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The website address may also begin with https：//—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone. Keep your password(密碼) safe: Most online sites require a user name and password before placing an order. Treat your passwords with care. 文章大意：本文介紹了網(wǎng)上黑客盜用信用卡資料進行欺騙的行為以及我們應(yīng)采取的防范措施。 5．What de most people worry about the Internet according to this passage? A.

Cheating. B. Sale. C. Payment. D. Safety. 答案：A　詞義猜測題。根據(jù)第一段第二句(你的信用卡信息可能會在非法網(wǎng)站出售)和第四段最后一句(可采取下列措施防止受欺騙)可推知此題答案為A。 7．How can the thieves get the information of the credit card? A. The customers give them the information. B. The thieves steal the information from websites. C. The customers sell the information to them. D. The thieves buy the information from credit-card firms. 答案：B　推理判斷題。根據(jù)文章第二段的提醒(當心那些提供便宜商品或服務(wù)的網(wǎng)站)和第三段前兩句可推知此題答案為B。也可采用排除法：根據(jù)文章內(nèi)容，排除A和C(并且這兩項也不合情理)；根據(jù)文章第四段第一句可知選項D也不正確。因此選B。 8．You are shopping on the site: http: //www. shopping. com, and you want to buy a TV set, what does this article suggest to do?
