3、s of crime in which someone wrongfully obtains and uses another persons personal data in some way that involves fraud or deception, typically for economic gain. The numbers associated with identity theft are beginning to add up fast these days. A recent General Accounting Office report estimates tha

4、t as many as 750,000 Americans are victims of identity theft every year. And that number may be low, as many people choose not to report the crime even if they know they have been victimized. Identity theft is “an absolute epidemic,“ states Robert Ellis Smith, a respected author and advocate of priv

5、acy. “Its certainly picked up in the last four or five years. Its worldwide. It affects everybody, and theres very little you can do to prevent it and, worst of all, you cant detect it until its probably too late.“ Unlike your fingerprints, which are unique to you and cannot be given to someone else

6、 for their use, your personal data, especially your social security number, your bank account or credit card number, your telephone calling card number, and other valuable identifying data, can be used, if they fall into the wrong hands, to personally profit at your expense. In the United States and

7、 Canada, for example, many people have reported that unauthorized persons have taken funds out of their bank or financial accounts, or, in the worst cases, taken over their identities altogether, running up vast debts and committing crimes while using the victims names. In many cases, a victims loss

8、es may include not only out-of-pocket financial losses, but substantial additional financial costs associated with trying to restore his reputation in the community and correcting erroneous information for which the criminal is responsible. According to the FBI, identity theft is the number one frau

9、d committed on the Internet. So how do job seekers protect themselves while continuing to circulate their resumes online? The key to a successful online job search is learning to manage the risks. Here are some tips for staying safe while conducting a job search on the Internet. 1. Check for a priva

10、cy policy. If you are considering posting your resume online, make sure the job search site you are considering has a privacy policy, like CareerB. The policy should spell out how your information will be used, stored and whether or not it will be shared. You may want to think twice about posting yo

11、ur resume on a site that automatically shares your information with others. You could be opening yourself up to unwanted calls from solicitors(推销员). When reviewing the sites privacy policy, youll be able to delete your resume just as easily as you posted it. You wont necessarily want your resume to

12、remain out there on the Internet once you land a job. Remember, the longer your resume remains posted on a job board, the more exposure, both positive and not-so-positive, it will receive. 2. Take advantage of site features. Lawful job search sites offer levels of privacy protection. Before posting

13、your resume, carefully consider your job search objectives and the level of risk you are willing to assume. CareerB, for example, offers three levels of privacy from which job seekers can choose. The first is standard posting. This option gives job seekers who post their resumes the most visibility

14、to the broadest employer audience possible. The second is anonymous (匿名的) posting. This allows job seekers the same visibility as those in the standard posting category without any of their contact information being displayed. Job seekers who wish to remain anonymous but want to share some other inf

15、ormation may choose which pieces of contact information to display. The third is private posting. This option allows a job seeker to post a resume without having it searched by employers. Private posting allows job seekers to quickly and easily apply for jobs that appear on CareerB without retyping

16、their information. 3. Safeguard your identity. Career experts say that one of the ways job seekers can stay safe while using the Internet to search out jobs is to conceal their identities. Replace your name on your resume with a generic（泛指的) identifier, such as “Intranet Developer Candidate,“ or “Ex

17、perienced Marketing Representative.“ You should also consider eliminating the name and location of your current employer. Depending on your title, it may not be all that difficult to determine who you are once the name of your company is provided. Use a general description of the company such as “Ma

18、jor auto manufacturer,“ or “International packaged goods supplier.“ If your job title is unique, consider using the generic equivalent instead of the exact title assigned by your employer. 4. Establish an email address for your search. Another way to protect your privacy while seeking employment onl

19、ine is to open up an email account specifically for your online job search. This will safeguard your existing email box in the event someone you dont know gets hold of your email address and shares it with others. Using an email address specifically for your job search also eliminates the possibilit

20、y that you will receive unwelcome emails in your primary mailbox. When naming your new email address, be sure that it doesnt contain references to your name or other information that will give away your identity. The best solution is an email address that is relevant to the job you are seeking such

21、as . 5. Protect your references. If your resume contains a section with the names and contact information of your references, take it out. Theres no sense in safeguarding your information while sharing private contact information of your references. 6. Keep confidential(机密的) information confidential

22、. Do not, under any circumstances, share your social security, drivers license, and bank account numbers or other personal information, such as race or eye color. Honest employers do not need this information with an initial application. Dont provide this even if they say they need it in order to co

23、nduct a background check.

The answer has changed over the years. Two hundred years ago, you were

44、 old at 35. That was the average life expectancy then. At the turn of the 19th century, as medical knowledge advanced, the average life expectancy increased to 45. In 1950, 70-year olds were really old. Today, a healthy 70-year-old is looking forward to many more active years. So, how old is old? Th

45、e answer is one youve heard many times, from all sorts of people. “You are as old (or young) as you feel.“ The calendar simply tells you how many years you have lived. Your body tells you how well youve lived. “Youth“, wrote an unknown author, “is not a time of life-it is a state of mind. Nobody gro

46、ws old by living a number of years; people grow old by deserting (抛弃) their ideals.“ Old is a point of view. Alice Brophy, when she was with the New York City Commission for the Aging, said, “It annoys me when people say, Gee, you look young for your age. What does that mean? Is there some model tha

47、t you re supposed to look a certain way at 65 and 75 and 85? You know, you can die old at 30 and live young at 80.“ It is often believed that most older people are in poor health. But the fact is that there are neither biological nor physiological (生理学的) reasons to connect poor health with growing o

48、lder. Older people are more likely to be affected with illness and physical disabilities than you are, but old age itself is not a disease. Its possible to remain physically fit throughout your life. （分数：177.50）(1).Which of the following statements is NOT true according to the passage?（分数：35.50）A.The concept of “old“ is differently defined in different times.B.Nobody can remain physically healthy throughout the life.
