Although websites such as Facebook and MySpace experienced rapid growth during the middle of the first decade of the 21st century, some users remain unaware of the fact that the information they post online can come back to haunt them. First, employers can monitor employees who maintain a blog, photo diary, or website. Employers can look for controversial(引起争议的) employee opinions, sensitive information disclosures, or wildly inappropriate conduct. For example, a North Carolina newspaper fired one of its features writers after she created a blog on which she wrote about the strange things of her job and coworkers without signing her real name.

The second unintended use of information from social networking websites is employers who check on prospective employees. A June 11, 2006 New York Times article reported that many companies use search engines and social networking websites such as MySpace, Xanga, and Facebook to conduct background checks on college campuses. Although the use of MySpace or Google to check a student’s background is somewhat unsettling to many undergraduates, the Times noted that the use of Facebook is especially shocking to students who believe that Facebook is limited to current students and recent alum(校友).

Corporate employers are not the only people interested in college students’ lives. The third unintended use of social networking websites is college administrators who monitor the Internet — especially Facebook — for student bad behavior. For example, a college in Boston’s Back Bay expelled (除名) its student Government Association President for joining a Facebook group highly critical of a campus police sergeant. In addition, fifteen students at a state university in North Carolina faced charges in court for underage drinking because of photos that appeared on Facebook.

Although more users of websites such as Facebook are becoming aware of the potential dangers of online identities, many regular users still fail to take there basic security precautions(警惕). First, only make your information available to a specific list of individuals whom you approve. Second , regularly search for potentially harmful information about yourself that may have been posted by mistake or by a disgruntled

(不满的)former associate. Thrid, never post obviously offensive material will likely make its way to the wider world. By taking these simple steps, members of the digital world can realize the many benefits of e-community without experiencing some of the damaging unintended consequences.

1.The main purpose of the passage is to _____.

A. explain the growth of the digital world from the view of privacy

B. discuss the risks of the digital world and suggest ways to protect yourself

C. propose steps Facebook, MySpace and Google can take to protect user privacy

D. illustrate(说明) potential unintended uses of private information

2.The writer implies that users should take all of the following actions to protect their online privacy EXCEPT _____.

A. know to whom you make your online information available

B. actively hunt for damaging information posted about you or under your name

C. speak with employers to inform them of any misinformation published about you

D. avoid uploading information that would be extremely damaging if it were discovered

3.According to the passage, which of the following does the author imply?

A. Information obtained unwillingly from the Internet is permitted in court.

B. It is impossible to protect yourself from unintended uses of information online.

The rapid growth in skyscrapers worldwide, most of which have large windows, has led to a high demand for window washers. Though the job is well-paid, it is dangerous and accidents are not uncommon. However, if Israel-based start-up Skyline Technologies has its way, the dangerous job may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.

Much like humans, Ozmo, sitting on platforms hanging from the buildings, uses its arms and brushes to clean the dirt on the glass. A 3D map of the building’s surface programmed into its system allows the robot to skillfully deal with any obstacle it is likely to meet, as it moves up and down the buildings. The robot will self-correct and move around every obstacle that it might have met so as not to break a window.

Unlike present window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled (蒸馏的) water to do the job. Yaron Schwarcz, CEO of Skyline Robotics explains, “We are environmentally friendly.”

Ozmo is also expected to be much more efficient than its human counterparts. While it presently takes three cleaners 480 hours each to clean windows of a 40-storey glass building, the robot will be able to do it in 80 hours. However, unlike other robots, Ozmo will not replace human workers, and only make their jobs safer by making them supervisors, who will be controlling the operation from the safety of the ground.

Whether Ozmo, which is still being tested, does as good a job as humans remains to be seen. If things go well, its creators have much bigger ambitions for Ozmo. Schwarcz told Forbes Magazine, “Window cleaning is just the tip of the iceberg. We plan to replace all tasks that are dangerous and dirty.”

1.Why is Ozmo friendly to our environment?

A.It uses less soap than other robots.

B.It depends on solar energy.

C.It makes our ecosystem more balanced.

D.It consumes nothing made from chemicals.

2.What can we infer from the passage?

A.Like cleaning windows, a well-paid job is usually dangerous.

B.Without humans supervising, Ozmo could have performed better.

C.Ozmo can save 400 hours per building compared to a human cleaner.

D.Ozmo can’t be stopped by obstacles with its advanced system.

3.What does the underlined part “the tip of the iceberg” mean?

A.A small part of a big plan.

B.As cool as the iceberg.

C.The most advanced technology.

D.The leading role in the modern world.

4.What is the best title for the text？

A.Robots make a difference.

B.Meet Ozmo, the window cleaning robot.

C.Supervise Ozmo, human safe.

D.Intelligent Ozmo becomes known worldwide.

The rapid growth in skyscrapers worldwide has led to a high demand for window washers since most of these buildings feature large glass panes (窗格) to highlight their breathtaking views.

Though the job offers a handsome salary, dangling alongside multi-story structures is dangerous, and accidents are not uncommon. However, if Israel-based company Skyline Technologies has its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot.

"As a society, we've become too comfortable watching people hanging off the sides of 30-story buildings," says Yaron Schwarez, co-founder and CEO of Skyline Robotics. "No salary could justify allowing people to put their lives in the hands of a system of ropes."

Much like humans, Ozmo is placed on platforms suspended from the buildings and uses its arms and brushes to clean the dirt on the glass panes. A 3D map of the building's surface programmed into its system allows the robot to skillfully handle obstacles as it moves up and down the structure. Computer vision and touch sensors enable it to move out of the way in case of unexpected events, such as the sudden opening of a window.

Unlike current window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled water (蒸馏水) and a process called dirt absorption to do the job. Schwarez explains, "We use pure water to absorb and remove the salts, the minerals, the oils, and the dirt from the building. We are environmentally-friendly."

Ozmo is also expected to be much more efficient than humans. While it currently takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers. It will only make their jobs safer by lifting them to the role of supervisors, who will be remotely controlling the operation from below.

Whether Ozmo, which is still undergoing testing, does as good a job as human remains to be seen.

1.Which of the following can best replace the phrase "has its way" in paragraph 2?

A.Succeeds. B.Hesitates.

C.Struggles. D.Exists.

2.What can we learn about Ozmo from the passage?

A.It requires chemicals to clean.

B.It has trouble crossing obstacles.

C.It operates with great efficiency.

D.It works without human helpers.

3.What is the author's attitude towards the future application of Ozmo?

A.Optimistic.

B.Doubtful

C.Unconceded.

D.Objective.

4.What is the best tile for the text?

A.Ozmo: a Double-edged Sword.

B.Ozmo: a Smart Window Cleaner.

C.Window Washing: a Dangerous Job.

D.Window Washing: a Blessing in Disguise.
