"二、阅读理解:阅读下面的短文,根据文章内容从A、B、C、D三个选项中选出一个最佳选项。

While there are still many people who don't feel comfortable using a credit card to buy over the Internet, e-commerce is absolutely here to stay. If you take a few precautions buying over the Internet can actually be safer than using your credit card in a restaurant.

Just as you should notice your surroundings and suspicious-looking people when withdrawing (提取) money from an ATM, you should know how to recognize the warning signs of Internet tricks and take steps to avoid being a victim when shopping online. Here are some good tips to remember when shopping online:

Before submitting your personal information to a site, try to find out how the information may be used and whether it will be sold to or shared with other businesses. If you don't like what you read, shop somewhere else.

Don't provide personal information such as address , telephone number, social security number , or e-mail address unless you know who you are providing the information for, why it' s being requested , and how it will be used .

Use a credit card, not a debit card (借记卡) for shopping on the internet. Debit cards don't have the same protection as credit cards.

Carefully review your credit card and bank statement each month for unknown charges and inform your credit card company or bank immediately if you notice any charges you didn't know about.

Clean your computer with free online software that detects spy-ware and install a firewall (防火墙) to ensure the sites you shop on don' t install spy-ware on your computer.

"二、阅读理解:阅读下面的短文,根据文章内容进行判断,正确为“T”,错误为“F”。

It is amazing to note that the Internet is still such a new device,and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet,a big online company can be run by only two guys in their garage. So it is only reasonable then,that people shopping online would be a little leery of the security levels.
Internet giants such as Microsoft knew consumer confidence was the key to getting virtual(虚拟的) shopping off the ground,and they work hard to make people feel safe to shop online.
Credit card companies,too,quickly saw the potential for online shopping,and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases,many credit card companies will happily refund(退还) your money and then set their claws on the company that wronged you. Now that’s buying power!
There are other bonuses for online shoppers,of course. No line"
