To tweet, or not to tweet?
A guide to the social networking/ microblogging service Tewitter
SINCE its creation in 2006, Twitter, the social networking service, has taken cyber space by storm. At first glance it might seem like Facebook, but Twitter is in a league of its own, connecting people with fast-paced updates. It has become a place for activities, celebrities, businesses and everyday people to let others know about videos, opinions, interesting news, advertisements-and, yes what they are eating for lunch.
Twitter: n. a free social networking service that connects users through fast-paced status updates.
Twitter-er: n. one who uses Twitter.
Tweet: n. short updates or messages, of 140 characters or less, wh ich are posted on your profile and sent to your followers.
Retweet (RT): n. unofficial Twitter feature that indicates a re-posting of a tweet from another user. Often uses the text RT@username (of the original source) before the post.
Follower: n. one who receives another user’s updates on his or her Twitter profile.
Direct message: n. a private message sent from one Twitter-er to another.
The phenomenon includes a host of new vocabulary terms and concepts that every self-respecting Twitter-er should know. Here’s a quick course on Twitter.
So you’ve finally been swept up by the techno-tide and gotten a Twitter account. But what to write? Who knew 140 characters could be so overwhelming?
Darren Rowse of the TwiTip blog(www.twitip.com) recommends a two- step tweeting process: figure out what your follows want, and then give it to them. Some combination of cool links, conversation- starting quotes or questions , retweets and photos works well, Rowse writes.
Keep in mind that Twitter doesn’t directly offer photo hosting. You will need to use a third-party site like TwitPic (www.twitip.com) to upload your photos. Other sites, like TwitVid (tweetdeck.com/beta) can be used to post videos.
If you th ink the Twitter Web Site too complicated, try a Twiiter client—Tweetdeck(tweetdeck. Com/beta) and the Mac-only Tweetie(www. stebits. com)are popular, and both also are available as iPhone apps(應用程序).
Even without an iphone, you can update you Twitter on the go. After adding your phone number to your Twitter account, you can text updates to 40404(check Twitter’s Web site for numbers to use outside the United States)
But no matter how you tweet, remember that people can see what you post, and Twitter might not be the best place to complain about your boss, even if you make your Twitter private, your followers may not share your sense of discretion.
Twitter is crowded with celebrith accounts. The famous , who once avoided the media in their private lives, are posting everything on Twitter for all the cyber world to see, gathering followers in the millions. Who’s leading the celebrity pack? TwitterCounter(www.twittercounter.com), a site that tracks the most popular Twitter users, lists Ashton Kuntcher and former fashion model, as the nost popular Twitter-er with, as of our publication date, 2,691,112 followers.

Dorothea Shaw is 71 years old and nearly blind, and she chose to live alone far away from people. She lives in Belize — a county the size of Wales with a population only that of Swansea. Her home is at Gales Point, a tiny village which can be reached only by sea or air; after a 10-mile walk into the hills one finally reaches a piece of land and two small houses so hidden in the thick over-grown forest that only a handful of people know Dorothea is there.
She lives happily and totally alone – growing her vegetables, looking after her trees and dogs, cats and chickens. Once a month or so an old friend passes by with her food supplies and letters-usually including a letter from her sister in Scunthorpe and some bits of clothing from friends in Canada. Sometimes a local man will come and cut wood for her and a group of British soldiers will come across her and be greeted with the offer of a cup of coffee.
At night she lies in her tiny sleeping room with the dogs on the floor, the cats on the table near the typewriter and one of the hens settled down in a corner of the bookshelf, and listens for hours to any Spanish, English, German or French broadcasts she can find on her radio. Sometimes she gets lonely but most of the time the animals and the radio are company enough.
But recently the very things that she had tried to get free from so well have begun to catch up with her. The peace of the forest has been destroyed by the noise of earth-moving machines not many miles away. What she once only heard of distantly on the radio is now on her doorstep. Things began to change three years ago. The new main north-south road in Belize was cut through the forest only four or five miles away. “Now more people know I’m here.” She says. “I feel more and more uneasy each day.”
小題1:Dorothea’s small houses ________.    
A.are entirely surrounded by trees
B.have always been her home
C.were built for just a few people
D.are in a county with the same population as Wales
小題2:Dorothea lives in the tiny village because ________.
A.she doesn’t like living near peopleB.she is too old to move
C.machines destroyed her homeD.there’s nowhere else for her to live
小題3: Dorothea doesn’t get lonely since she has _______ with her.
A.her sisterB.some animalsC.friends from CanadaD.a postman
小題4:Dorothea spends a lot of time __________.
A.growing all the food she needsB.cutting down trees
C.listening to the radioD.studying languages

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項,并在答題卡上將該項涂黑。
I was helping in my son’s classroom when I spotted a poster that reads, “Sticks and stones
may break my bones but words can break my heart”. I started thinking.
Teachers are such an important part of a child’s life. A teacher’s support determines how safe a child feels in school. His inspiration determines how much risk a child will take in the classroom, his understanding determines how important a child feels in school and his love determines a child’s motivating and attitude toward education. And the effect a teacher has on a child doesn’t end when the school bell rings at the end of the day. Rather, those feelings developed in the classroom go home with the child and, in a large part, determine what sort of evening the child and the family have. The importance of a teacher to a child is fantastic and cannot be over-emphasized.
All my children are fortunate to have remarkable teachers. Consequently, the three of them love going to school almost as much as they love using teacherisms. For example, one of Hannah’s favorite phrases in used when I mess up. She looks at me with understanding and says, “It’s okay to make mistakes, mama, because you’re only learning.” Rachael’s favorite phrase is used to start most of her jobs; with a glow in her eye, she says, “I’m just going to do my best, mama, because that’s all I can do!” But perhaps my favorite is Jacob’s response to his sisters when one of them says something he doesn’t like. With his hand on his heart he says, “Don’t say that because words can break my heart.”
Like most parents, I hear teacherisms daily. And every time I hear one, my heart floods with gratefulness for the wonderful teachers who make my children feel safe, important, and successful in the classroom, and who are helping my children achieve emotional good health. There is much talk today how to measure a teacher’s worth. I think we need only look at the students. Children mirror teachers’ words and actions, and the content of those reflections shows teacher’s greatness.
51.Teachers are important to students in that________.
A.they equip them with book knowledge
B.they help free the parents from worries
C.they guarantee each family a happy evening
D.they help keep them emotionally healthy
52.The three children’s examples are used to show that________.
A.they are lucky to have wonderful teachers
B.they can eventually develop into good teachers
C.they are sometimes mentally hurt by the teachers
D.they have a successful performance in school
53.To his mother, what the boy says possibly sounds________.
A.ridiculous B.convincing       C.humorous D.inspiring
54.The underlined word “teacherisms” probably refers to “________ ”.
A.how teachers normally deal with their students
B.what teachers usually say to their students
C.why teachers seem important to their students
D.where teachers agree with their students

D
An “apple-polisher” is one who gives gifts to win friendship or special treatment. It is not exactly a bribe(賄賂), but is close to it.
“Apple-polishing” is as old as human society, but the phrase itself is recent, about 50 years old. It comes from the schoolroom. For a long time, some schoolboys would leave a shiny(有光澤的,發(fā)光的) apple on the teacher’s desk. They would rub and polish the apple to give it a bright shine, so as to make it look more tasty. Such a gift, the students hoped, might make the teacher shut her eyes to their poor work and give them a good mark.
All sorts of people are apple-polishers, including politicians and people in high offices—almost everybody.
There are other phrases meaning the same thing as “apple-polishing”— “soft-soaping” or “buttering-up”. A gift is just one way to “soft-soap” somebody, or to “butter him up”.
Another way that is just as effective as apple-polishing is flattery, giving someone high praise — telling him how good he looks, or how well he speaks, or how wise he is. Flattery, of course, is the cheapest kind of “apple polishing”.
To flatter another costs you nothing and you can give it as freely as you want. And you can always find somebody eagerly looking for it.
53. An “apple-polisher” is one who ________.
A. tries to please someone to get favor   
B. bribes with money to get something
C. is really friendly to everyone around him
D. plants apple trees and polishes his apples every day
54. Why did the students polish the apple for their teacher?
A. They hoped that she would not pay attention to them.
B. They didn’t want her to wash the apple by herself.
C. They wished to draw her attention.
D. They longed for her giving them a good mark.  
55. According to the passage, the cheapest way to please someone is ________.
A. to flatter him                                               B. to bribe him
C. to talk freely with him                             D. to play jokes on him
56. The author seems to suggest that ________.
A. nobody likes to be flattered                    B. very few people apple-polish others
C. apple-polishing is a kind of bribe            D. many people like to be soft-soaped
