    　　Computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversations.

    　　E-mail, screensavers, and electronic greeting cards can carry a secret code which is able to turn on the computer's micro-phone, make a recording, and forward it to someone else without the user's knowledge.

    　　In fact any attachments(附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy.

    　　Experts say people should always think twice about opening attachments because—although rat common—bugging(窃听) by computer can, and has been done.

    　　Bill Lyons, head of the Internet Security Company Finjian, said, “People in the army have tested this and you can be sure, if people in general are aware of(知道) it, then computer hackers are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments. ”

    [　　]

    A．may know nothing about it

    B．must turn off the computer

    C．can do nothing but wait

    [　　]

    A．tools can easily be got to tie dangerous codes to E-mails

    　　Traveling can be a way to gain life experiences, especially during Spring Break－a week long school vacation in the United States．But what if you’re a student and don’t have enough money for a trip? Don’t worry．Here are some useful suggestions．

    　　●Save：This probably is the most important preparation for traveling．Cut expenses to fatten your wallet so you’ll have more choices about where to go and how to get there．

    　　●Plan ahead：Don’t wait until the last minute to plan your trip．Tickets may cost more when bought on short notice．Giving yourself several months to get ready can mean security(安全)and savings．

    　　●Do your homework：No matter where you go, research the places you will visit．Decide what to see．Travel books will provide information on the cheapest hotels and restaurants．

    　　●Plan sensibly：Write down what you expect to spend for food and hotels．Stick to your plan or you may not have enough money to cover everything．

    　　●Travel in groups：Find someone who is interested in visiting the same places．By traveling with others you can share costs and experiences．

    　　●Work as you go：Need more money to support your trip? Look for work in the places you visit．

    　　●Go off the beaten path：Tourist cities may be expensive．You may want to rethink your trip and go to a lesser-known area．Smaller towns can have many interesting activities and sights．

    　　●Pack necessary things：The most important things to take are not always clothes：Remember medicine in case you get sick and snacks in case you cannot find a cheap restaurant．

    　　●Use the Internet：The Net can help to save money．Some useful websites include www．Travelocity．com, www．bargains-lowest fare．com and www．Economic travel．com．

    　　By planning sensibly, even students can enjoy the travel．Your travel experiences will be remembered for a lifetime．

    阅读理解

    　　BELIEVE it or not, the color of the tie Barack Obama wore to the inauguration(就职典礼)is now a hotly debated topic．The level of public interest in Obama’s tie might seem strange but many people believe his choice will symbolize the type of government he plans to run, as the color of a politician’s tie is thought to convey ideas of power, trustworthiness and more．

    　　Polities of ties．

    　　It may be the least practical item of male dress, but it is arguably the most expressive．In the UK and many other coun－tries around the world, conservative(保守的)politicians may wear a blue tie and their liberal opponents a red one．In America, the colors go the other way round．The Republicans have in recent years become associated with the color red, and the Democrats with blue．But in spite of this, bush wears blue ties more often than any other color．

    　　What they mean

    　　According to Sharon Haver, editor of focusonstyle．com, in America the feelings associated with colors overrule their political significance．“a guy who want to be regarded as strong and in charge would wear red,” Haver says．Unsurprisingly, the business tycoon Donald Trump is known for wearing red ties．But what about blue? According to Haver, “Blue is a softer color… Look at the sky．It’s peaceful and calm and trustworthy．”

    　　Selecting the right tie for the right occasion．

    　　●Perfect job interview tie．

    　　Perhaps no other tie －wearing occasion is as important as the job interview．Gilchrist, the fashion expert, advises playing it safe and choosing a conservative one．Best choices are solids, stripes or small patterns．An excellent color is burgundy(深红色)or another serious color．Avoid pink or yellow, which suggests that the wearer lacks gravity．

    　　Pattern ties, Gilchrist suggests, should be limited to a maximum of three colors．A striped tie is a safe choice as this is acceptable to everyone．Last, Gilchrist recommends saving the expensive “hip” tie for those applying for glamorous creative jobs．

    　　●Date－night tie

    　　When picking out the right tie for taking a girl out on a date, spend more time considering color than pattern．According to studies, women are attracted to men wearing the color blue, because blue gives the image of a “stable, faithful, constant, always there” person．So what is the worst color to wear on a date? “Flattened caterpillar(毛虫)yellow－green,” according to Gilchrist, “it will repel both sexes equally．”

    (1)

    Why are people interested in the tie that Obama wore to the inauguration?

    [　　]

    A．

    Because they think the tie he wore will enable them to know about his personalities and policies．

    B．

    Because they want to advise him how to select an appropriate tie for such a big occasion．

    C．

    Because they think the tie will tell if he is trustworthy as they expected when he assumes office．

    D．

    Because they believe the tie is an essential part of dressing to a mature politician like Obama．

    (2)

    What can we infer about Bush, the former president, from the passage?

    [　　]

    A．

    He was probably liberal in his policies when he was in power．

    B．

    He was a Republican when he served as president．

    C．

    He wore only blue ties and had no ties of alternative colors．

    D．

    He wanted to make himself unique by the tie that he wore．

    (3)

    The example of “the business tycoon Donald Trump” is given to _________．

    [　　]

    A．

    prove that color reflects people’s feelings to a certain degree

    B．

    show that Donald is so wealthy that he can afford expensive ties

    C．

    tell that Donald is physically strong and can handle everything

    D．

    explain that red is a popular color, especially with businessmen

    (4)

    Which of the following statements is TRUE according to the text?

    [　　]

    A．

    Ties can be ignored by politicians since they are the least practical item of male dress．

    B．

    Do choose ties carefully before dating, because it is the most important occasion．

    C．

    Why to avoid pink or yellow ties in job interviews is that they don’t match the atmosphere．

    D．

    The more colorful the tie is, the more likely you’ll get the job you want．
