Microblogging is a broadcast medium in the form of blogging. A microblog differs from a traditional blog in that its content is typically much smaller, in both actual size and aggregate file size. Microblogs “allow users to exchange small elements of content such as short sentences, individual images, or video links”.
As with traditional blogging, microbloggers post about topics ranging from the simple, such as "what I'm doing right now," to the thematic(主题的), such as "sports cars.” Commercial microblogs also exist, to promote (促进) websites, services and/or products, and to promote collaboration within an organization.
Some microblogging services offer features such as privacy settings, which allow users to control who can read their microblogs, or other ways of publishing rights besides entering the web-based interface.(界面) These may include text messaging, E-mail, or digital audio.
The first microblogs were known as tumblelogs. The term was invented in a blog post on April 12, 2005. However, by 2006 and 2007, the term microblog came into greater usage for such services provided by Tumbler and Twitter. Other leading social networking websites Facebook, MySpace, LinkedIn, and XING also have their own microblogging features, better known as status updates.
Several studies, especially by Harvard Business School have tried to analyze the usage behavior of Microblogging services. Many of these studies show that for services such as Twitter, there is a small group of active users contributing to most of the activity.
Twitter, Facebook and other microblogging services are also becoming a platform for marketing and public relations, with a sharp growth in the number of social media marketers. The Sysomos study shows that this specific group of marketers on Twitter is much more active than general user population, with 15% following more than 2,000 people.Why is a microblog different from a traditional blog?

Then comes July, and with it examinations, but these are soon finished and with them ends the school year. Boys and girls have nearly two months’ holiday before them as they leave school by train and car to return home to their fathers and mothers.
The summer holidays are the best part of the year for most children. The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields. Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside. Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something that they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpoor or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside? I think it is the sand, sea and sun more than any other things. Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that make the seaside what it is.After the examination, pupils leave for home________
| A．by train only |
| B．by air |
| C．by bike |
| D．by either train or car |
July and August are the brightest months for most children, for they can_____.
| A．stay with their parents for all the vacation. |
| B．do more reading |
| C．play out-of-door |
| D．meet their old friends |
Children like the seaside so much, because they can ______.
| A．swim in the sea |
| B．play with the sand |
| C．take a sun bath |
| D．do all of the above |
Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That's every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles.”Miss Gogers was teaching her class_________.
| A．how to telephone |
| B．about electricity |

You don’t know what you’ve got until it’s gone. I’ve learned that through my personal experiences. A few months ago, I woke up deaf in one ear. I did not pay much attention to it at first. It felt that I had water in my ear. However, I began to hear less and less out of that ear. I even had to ask people to talk into my other ear so that I could hear them. I didn’t realize how serious it was until late in the day (为时太晚). One evening, when I was sitting on my bed doing chemistry homework, I fell off my bed. When trying to get up, I was incredibly dizzy (头晕的).
I went to see a doctor and he told me that hearing loss was common. However, hearing loss is usually bilateral, or occurs in both ears. He said that my hearing should come back within a week. After about a week the dizziness eventually went away, but the hearing loss did not. The medicine helped and I gained some of my hearing back. After many hearing tests, the doctor diagnosed (诊断) that I had permanent hearing loss in that ear.
School became harder for me because I couldn’t hear my teachers. I was very depressed. Finally, I bought a hearing aid. With the hearing aid, my hearing is almost back to normal. It makes school and group conversations easier.
My friends, teachers and even complete strangers always ask me questions about hearing loss. I answer them patiently. I never get offended because I know this is new to them. I am delighted that I can teach them something new.
What I have learned from this particular situation is that when things are desperate（绝望的；急切的）, there is always something good that can come out of it. My experiences have given me an opportunity to teach people about hearing loss and also taught me about the value of hearing.What happened to the author?

Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.
Susanna Rohm said she had experienced a parent’s worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. “I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的),” Rohm told a local newspaper. “Then I noticed that he looked like he wasn’t alive.” In dismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.
“I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, ‘Go and ask your parents to call 911,’” Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.
Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. “I was thinking we’d better give her a helping hand instead of getting scared,” Ethan said. “I told her to push on the baby’s chest five to ten times a minute with only two fingers, tilt back the baby’s head, plug the baby’s nose and breathe into the baby’s mouth,” Ethan said in an interview.
At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. “If the little boy hadn’t shown me what to do right there, my baby would probably not be alive right now,” Rohm said.We can learn from Paragraph 1 that in the US, .
| A．CPR is considered important by most people |
| B．most children are taught how to perform CPR |

| A．grateful | B．regretful |
| C．surprised | D．ashamed |
Imagine shopping for clothes online and being able to run your hand across the screen of your computer or smartphone to feel the materials. That kind of simulation (仿真) technology could be available within the next five years.
“We’re talking about reinventing how computers interact （互动）with humans,” said Bernie Meyerson, IBM Vice President. Extending our sense of touch is one of the innovations (创新) IBM believes will change the world in the next five years, according to the company’s annual “Five in Five” list.
Smart machines will also be able to listen to the environment and highlight （强调；突出）the sounds we care about most. For instance, an advanced speech recognition system will tell new parents why their baby is crying. This kind of thing is not possible today, but with an advanced enough system, it’s actually possible.
In the near future, personal computers will be able to do more than recognize images and visual data. Their built-in cameras will be able to analyze features such as colors, and understand the meaning of visual media, such as knowing how to sort family photos.
Smart machines will also be able to smell. If you sneeze on your computer or cellphone, tiny sensors (传感器) in the machine will be able to analyze thousands of molecules (分子) in your breath. “It can give you an alarm and says, ‘Hey, you are probably sick, go to see your doctor immediately,’” Meyerson says.
Mark Maloo is a computer science professor from Georgetown University. He hopes the advances will encourage more students to study science, technology, engineering and math, preparing them to play a role in future innovations. He believes there’s little doubt that advances in computer technology over the next five years will make what now seems like science fiction a part of our everyday lives.The purpose of the text is to show us
| A．how smart machines will replace humans |

In the future, if you buy clothes online, you may .
| A．feel the materials of the clothes by touching the screen |
| B．ask your computer to give you some advice |
| C．ask your computer to make the decision for you |
| D．save a lot of money by using a smartphone |
How will a smart machine figure out that you are probably sick?
| A．By analyzing the thousands of molecules in your breath. |
| B．By analyzing your comments about your body condition. |
| C．By referring your condition to doctors. |
| D．By asking you to describe how you feel. |
