　　(2011·上海春招)

　　They like using the Internet.They have lots of pocket money to spend.And they spend a higher proportion of it online than the rest of us.Teenagers are just the sort of people an online seller is interested in, and the things they want to buy—games, CDs and clothing—are easily sold on the Web.

　　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(网络的)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 pay­as­you­go mobile telephones, they are sold in amounts such as ￡20 or $50 with a concealed 14­digit number that can be used to load the cash into an online account.

　　文章大意：现在很多英美青少年想用零花钱网购，购CD或衣服等，但如何实现网上便利付帐呢？

　　1．What does the underlined word “They” in paragraph 1 refer to?

　　A．Sellers.

　　B．Buyers.

　　C．Teenagers.

　　答案：C　细节理解题。从文章第一段“They like using the Internet... Teenagers are just the sort of people...”可知，此处They指代下文中的Teenagers，答案选C项。

　　2．According to the passage, which of the following statements is TRUE?

　　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　正误判断题。从第四段第二句中的“Most teenagers have access to the Internet at home or at school—88 percent in the US, 69 percent in the UK.”可知，在英国和美国超过了50%的青少年可以接触到网络，故答案选A项。

　　3．A new way to help teenagers shop online is to use______.

　　A．a new machine

　　B．special coins and notes

　　C．prepaid cards

　　D．pay­as­you­go mobile phones

　　答案：C　细节理解题。从最后一段中的第一句话可知，现在一个帮助青少年网络购物的方法是用预付卡，所以答案选C。

　　4．What is the passage mainly about?

　　A．Online shopping traps.

　　B．Internet users in the US and the UK.

　　C．New credit cards for parents.

　　D．The arrival of cyber pocket money.

　　答案：D　主旨大意题。从全文可知，本文主要告诉我们如何保证青少年上网购物的安全，以及就此所采用的新方法来保障他们的网络零花钱，据此D项能较好地概括大意。

　　B

　　The Internet has led to a huge increase in credit­card(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 credit­card 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 credit­card numbers were posted on a website，after the retailer refused to pay $ 157,828 to get back the information.

　　Credit­card 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 credit­card 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 credit­card information only if the website offers advanced secure system.

　　If the security is in place, a letter will appear in the bottom right­hand

　　corner of your screen.

　　The

　　website address may also begin with https：//—the extra “s” stands for secure.

　　If in doubt, give your credit­card information over the telephone.

　　Keep your password(密码) safe: Most online sites require a user name and password before placing an order. Treat your passwords with care.

　　文章大意：本文介绍了网上黑客盗用信用卡资料进行欺骗的行为以及我们应采取的防范措施。

　　5．What de most people worry about the Internet according to this passage?

　　A. A lot of stolen credit cards were sold on the Internet.

　　B. Fraud on the Internet.

　　C. Many websites are destroyed.

　　D. Many illegal websites are on the Internet.

　　答案：B　推理判断题。根据文章第一段(因特网已导致信用卡欺骗行为大量增加，你的信用卡信息甚至会在非法网站出售)可推知此题答案为B。

　　6．What is the meaning of the underlined word “fraud”？

　　A. Cheating.

　　B. Sale.

　　C. Payment.

　　D. Safety.

　　答案：A　词义猜测题。根据第一段第二句(你的信用卡信息可能会在非法网站出售)和第四段最后一句(可采取下列措施防止受欺骗)可推知此题答案为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 credit­card firms.

　　答案：B　推理判断题。根据文章第二段的提醒(当心那些提供便宜商品或服务的网站)和第三段前两句可推知此题答案为B。也可采用排除法：根据文章内容，排除A和C(并且这两项也不合情理)；根据文章第四段第一句可知选项D也不正确。因此选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?

　　A. Order the TV set at once.

　　B. Do not buy the TV set on this site.

　　C. E­mail the site your credit­card information.

　　D. Tell the site your password and buy the TV set for you.
