Dear Ms. Akella:
I was interested to read about your company in the online issue of "Technology Today." Perhaps your company's technology can help us.
I own a candy company in Tennessee. We (141) a variety of kinds of candy which are sold all over the USA and in other countries as well. As part of their work, my employees use heavy equipment and move large boxes every day. Sometimes they fall or hurt their backs. As a result, they (142) days of work. Everyone suffers from this situation.
These accidents cost my company a lot of money, and my employees suffer from health problems.
Rapid Technology's "cobots" may help. I understand that a "cobot" is like a robot. However, it is a robot that collaborates-or works with-people. So, you call it a "cobot." Is that correct？ I understand that people are (143) when they work with cobots. However, the article I read only discussed cobots at car companies. Could they also be used at a candy company？
We are very interested in cobots, but we are not sure if they would work here. What do you think？ Please reply via mail. Thank you.

In recent years, school administrators have blamed some campus fights on Internet conflicts and urged parents to keep watch on their childrens computer activity. But students who use the Web to let their 500 closest friends know what they are doing at all times are sometimes surprised that police are watching, too.
Police dont have special privileges on Facebook or MySpace. Students who want to go unobserved can change privacy settings so that their profiles are displayed only to a list of approved people. But the default(默认)settings leave those profiles open to many Internet users(in the case of Facebook)or all of them(in the case of MySpace).
Employers and college admissions counselors have examined online profiles of student applicants for some time. Police across the country have been doing the same for the past two or three years, said Kevin Quinn, a spokesman for the Minnesota-based National Association of School Resource Officers.
"If youre already familiar with the technology, it doesnt take you but a couple of minutes to hook into the student population and keep an eye on things," Quinn said.
An expedition into a thicket(丛林)of MySpace profiles found high school students discussing drugs, sex and fights. It was all publicly available(although in language that caused a reporter to blush).
Late last month, Fairfax County police announced the arrests of seven Chantilly area teenagers for trying to recruit Franklin Middle School students to a gang. That investigation was aided when a student showed the school resource officer gang symbols littering one of the suspects MySpace profiles.
Fairfax police say they pride themselves on addressing issues in schools before they develop into major problems. Keeping an eye on Facebook and MySpace has become an extra tool in that effort, they said.
Police officers scan social networking sites like Facebook or MySpace because_____.
A．they have some special privileges to do so
B．they may detect gang-fighting through the Net
C．it is easier to solve students" conflicts online
D．it is their duty to protect students" privacy
