   B. .

  A lazy Susan is an addition to a table，which is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable(轉(zhuǎn)盤(pán)) ， which usually moves the food in a circle when pushed by those at table. In this way,the food never has to be picked up and passed around the table. Instead, it remains in place as the lazy Susan is turned about.

  A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.

  Whether the lazy Susan is on a tabletop or within a cabinet，it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan，though it was referred to as a dumb wai?ter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daugh?ter complained she was always served last at table and，as a result，never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留聲機(jī)) ，which later developed into the lazy Susan.

  Regardless of who invented it,it wasn't until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rath?er than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson's or Edison's daughter, both of whom were named Su?san.

(   ) 5. According to the passage, a lazy Susan        .

   A.is a person who passes food at table

   B.is a waitress who helps move dinner tables

   C.is an additional round table in a dining room

   D.is a turntable that passes food around the table

(   ) 6. Why did Jefferson's daughter Susan complain she was served last when having meals?

   A.Because she was too lazy.

   B.Because she was the youngest.

   C.Because the table was too tall for her.

   D.Because the table couldn't move food for her. 

(   ) 7. From the passage, we can know that        .

   A.the lazy Susan was invented earlier than the phonograph

   B.Susan was the name of Jefferson's and Edison's daughter

   C.Jefferson and Edison invented the lazy Susan at the same time

   D.when people talk about a lazy waitress they use the term "Susan" 

(   ) 8. What's the main idea of the passage?

    A.What is a lazy Susan?

   B.When was the lazy Susan created?

   C.Why do inventions come from daily life?

   D.How was "dumb waiter" replaced by "lazy Susan"?

 They do it late at night when their parents are asleep. They do it in restaurants and while crossing busy streets. They do it in the classroom with their hands behind their back. They do it so much that their thumbs hurt.

  Spurred(刺激) by the unlimited texting plans offered by carriers like AT&T Mobility and Verizon Wireless, American teenagers sent and received an average of 2,272 text messages per month, according to the Nielsen Company一almost 80 messages a day.

  The phenomenon is beginning to worry physicians and psychologists. Dr. Martin Joffe, a pediatrician in Greenbrae，Calif.，recently surveyed students at two local high schools and said he found that many were routinely sending hundreds of texts every day.

  The rise in texting is too recent to have produced any conclusive data on health effects. But Sherry Turkle, a psychologist who has studied texting among teenagers in the Boston area for three years,said it might be causing a shift in the way adolescents develop.

  "Among the jobs of adolescence are to separate from your parents，and to find the peace and quiet to become the person you decide you want to be," she said. "Texting hits directly at both those jobs.”

  Psychologists expect to see teenagers break free from their parents as they grow into autono- mous adults，Professor Turkle went on， " but if technology makes something like staying in touch very,very easy, that's harder to do;now you have adolescents who are texting their mothers 15 times a day,asking things like, * Should I get the red shoes or the blue shoes?'" 

(   ) 5. The purpose of the first paragraph is to tell us        .

   A.American teenagers are addicted to texting

(   ) 6. According to psychologists, teenagers        as they grow into autonomous a-

dults.

    A.should keep in touch with their parents

   B.should live without modern technology

   C.need some freedom or independence

   D.needn't be independent from their parents

(   ) 7. Which of the following is TRUE according to the text?

   A.American teenagers are not allowed to use mobile phones in school.

   B.Texting can also affect American teenagers' studies.

   C.Texting has no bad effects on American teenagers' health.

   D.Parents are not worried about the effects of texting.

   A.texting helps narrow the generation gap between parents and kids

   D.texting can play a .negative role in teenagers' becoming autonomous adults

  The principal of New Milford High School has nearly 12,300 Twitter followers. He and his teachers use Facebook to communicate with students and parents，and students use it to plan e-vents. In class, teachers routinely ask kids to power up their cellphones to respond to classroom quizzes. Rather than ban cellphones, Sheninger calls them "mobile learning devices".

  "The Internet as we know it is the 21st century," he says. "It is what these students have known their whole lives. They're connected, they're creating, they're discussing."

He and others say working online also pushes education beyond the limits of school, allowing kids to broaden discussion of their work. And it forces them to do "authentic" work that gets tested out in the real world, as outside viewers see it and respond to it.

  "Being literate in 2011 means being digitally literate. " says Chris Lehmann. "It is naive (天真的) to think that kids raised online will respond to school the same way as previous genera?tions. Kids are coming to us bored, disconnected, and it's a challenge for us to figure out how to use the tools inherent in the real-time Web.”

  Perhaps the biggest objection to widespread use of social sites is the likelihood that kids will meet irrelevant or even offensive material―a fear that many teachers say is overblown.

  "We as educators need to do a better job of advertising and sharing the meaningful work done with social media," says Matt Levinson. "If you keep it out,kids are creating their own cultures in this space with no guidance from adults―and that's not responsible.”

  "The other big misconception is that schools with open Web access are simply letting kids play freely as if there's no structure," says Lisa Highfill, a longtime devotee of YouTuhe. She used it recently to show her students videos of tornadoes. Highfill says she chooses videos in ad?vance.

  "I don't just search in front of the kids," says Highfill. She admits that even with careful planning，learning online carries risks. But the risks shouldn't be overstated. " When we go on a field trip,when we go anywhere," she says, "we warn students of the dangers of where we're going.”

(   ) 5. In the opinion of Sheninger, social networking        .

   A.is almost the whole life of many kids

   B.gets kids to learn something schools forbid

   C.allows kids to complain about their learning

   D.has kids get feedback on their online work

(   ) 6. According to Chris,teachers are challenged to know        .

   A.how to make full use of social sites in class

   B.how to avoid looking foolish in using social sites

   C.how to connect kids with social media effectively

   D.how to deal with a digital generation in class

(   ) 7. The example of Highfill's using YouTube proves        .

   A.online learning is full of unexpected things

   B.it is a risk to open the Web to students at school

   C.teachers provide guidance on the Web access

    D.kids play freely if having access to the Web

(   ) 8. What might be the most suitable title for the passage?

   A.Social networking helps online learning

   B.Social sites are a wonderful place for kids

   C.Social networking sites are blocked at schools

   D.Social media find place in class
