根据下列短文，回答下列各题。 Like most people, Ive long understood that I will be judged b

y my occupation, that my profession is a gauge people use to see how smart or talented I am. Recently, however, I was disappointed to see that it also decides how Im treated as a person. Last year I left a professional position as a small-town reporter and took a job waiting tables. As someone paid to serve food to people, I had customers say and do things to me I suspect theyd never say or do to their most casual acquaintances. One night a man talking on his cell phone waved me away, then beckoned (示意) me back with his finger a minute later, complaining he was ready to order and asking where Id been. I had waited tables during summers in college and was treated like apeon (勤杂工) by plenty of people. But at 19 years old, I believed I deserved inferior treatment from professional adults. Besides, people responded to me differently after I told them I was in college. Customers would joke that one day Id be sitting at their table, waiting to be served. Once I graduated I took a job at a community newspaper. From my first day, I heard a respectful tone from everyone who called me. I assumed this was the way the professional world worked--cordially. I soon found out differently. I sat several feet away from an advertising sales representative with a similar name. Our calls would often get mixed up and someone asking for Kristen would be transferred to Christie. The mistake was immediately evident. Perhaps it was because money was involved, but people used a tone with Kristen that they never used with me. My job title made people treat me with courtesy. So it was a shock to return to the restaurant industry. Its no secret that theres a lot to put up with when waiting tables, and fortunately, much of it can be easily forgotten when you pocket the tips. The service industry, by definition, exists to cater to others needs. Still, it seemed that many of my customers didnt get the difference between server and servant. Im now applying to graduate school, which means someday Ill return to a profession where people need to be nice to me in order to get what they want. I think Ill take them to dinner first, and see how they treat someone whose only job is to serve them. The author was disappointed to find that _______.

A.ones position is used as a gauge to measure ones intelligence

B.talented people like her should fail to get a respectable job

C.ones occupation affects the way one is treated as a person

D.professionals tend to look down upon manual workers

The Internet affords anonymity to its users, a blessing to privacy and freedom of speech.

But that very anonymity is also behind the explosion of cyber-crime that has 1 across the Web.

Can privacy be preserved 2 bringing safety and security to a world that seems increasingly 3 ？

Last month, Howard Schmidt, the nation's cyber-czar, offered the federal government a 4 to make the Web a safer place—a "voluntary trusted identity" system that would be the high-tech 5 of a physical key, a fingerprint and a photo ID card, all rolled 6 one. The system might use a smart identity card, or a digital credential 7 to a specific computer, and would authenticate users at a range of online services.

The idea is to 8 a federation of private online identity systems. User could 9 which system to join, and only registered users whose identities have been authenticated could navigate those systems. The approach contrasts with one that would require an Internet driver's license 10 by the government.

Google and Microsoft are among companies that already have these " single sign-on" systems that make it possible for users to 11 just once but use many different services.

12 , the approach would create a " walled garden" in cyberspace, with safe " neighborhoods" and bright "streetlights" to establish a sense of a 13 community.

Mr. Schmidt described it as a "voluntary ecosystem" in which "individuals and organizations can complete online transactions with 14 , trusting the identities of each other and the identities of the infrastructure 15 which the transaction runs. " Still, the administration's plan has 16 privacy rights activists. Some applaud the approach; others are concerned. It seems clear that such a scheme is an initiative push toward what would 17 be a compulsory Internet "drive's license" mentality.

The plan has also been greeted with 18 by some computer security experts, who worry that the "voluntary ecosystem" envisioned by Mr. Schmidt would still leave much of the Internet 19 . They argue that all Internet users should be 20 to register and identify themselves, in the same way that drivers must be licensed to drive on public roads.

【B1】

A．swept

B．skipped
