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(主題的), such as "sports cars.” Commercial microblogs also exist, to promote (促進(jìn)) 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.

It is estimated that some seven hundred million people, about half the world’s  adult population, are unable to read or write, and there are probably two hundred and fifty million more whose level is so slight that it is hardly called literacy(有文化).
Recently the attack on illiteracy had been stepped up. A world plan has been drawn up by a committee of UNESCO experts in Paris, as part of the United Nations Development Decade（十年計(jì)劃）,and an international conference of the subject has also been held.

In Africa there are at least one hundred million illiterate people, which is eighty to eighty-five percent of the total population. In Europe the figure is about twenty-four million; most of them are in Sothern Europe, with Spain, Italy, Portugal, Yugoslavia heading the list (the United Kingdom has about seven hundred thousand).

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.  Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily. Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.  For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!
【小題1】The writer of this passage must be ______.

A．a(chǎn)n AmericanB．a(chǎn) ChineseC．a(chǎn) professorD．a(chǎn) student
【小題2】Which of the following statements is TRUE according to the passage?
A．Friendships between Americans usually extend deeply into their families.
B．Friendships between Americans usually last for all their lives.
C．Americans always show their warmth even if they are very busy.
D．Americans will continue their friendships again even after a long break.
【小題3】From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.
A．warmly welcomed at the airport
B．offered a ride to his home
C．treated hospitably at his home
D．treated to dinner in a restaurant
【小題4】The underlined words “generous with our time” in Paragraph 3 probably mean ______.
A．strict with timeB．serious with time
C．careful with timeD．willing to spend time
【小題5】 A suitable title for this passage would probably be “______”.
A．Friendships between Chinese
B．Friendships between Americans
C．Americans’ hospitality
D．Americans’ and Chinese’s views of friendships

The Carnival of Brazil is an annual festival held 46 days before Easter, especially famous for the Carnival in Rio de Janeiro. Carnival celebrations are believed to have roots in the festival of Saturnalia, which, adapted to Christianity, became a farewell to bad things in a season of religious discipline to regret and prepare for Christ’s death and coming back to life.
Modern Brazilian Carnival dates back to Rio de Janeiro in 1641. It originally copied the European form of the festival, later taking in elements of Native American and African cultures.
In the late 19th century, the strings (弦樂器) were introduced in Rio de Janeiro. These were pageant (游行) groups that paraded through city avenues performing on instruments and dancing. Today they are known as blocks, consisting of a group of people who dress in costumes or special T-shirts with themes or logos. Blocks are generally connected with particular neighborhoods; they include both a music group and a lot of revelers.
Block parades have become an expressive feature of Rio’s Carnival. Today, they number more than 100 and the groups increase each year. Blocks can be formed by small or large groups of revelers with a clear title. Before the show, they gather in a square, then parade in sections of the city, often near the beach.
Carnival time in Rio is very interesting, but is also the most expensive time to visit Rio. Hotel rooms and other lodgings (住宿) can be up to four times more expensive than the regular rates. There are big crowds at some locations and life is far from ordinary in many parts of town.
【小題1】What can we infer from the first paragraph?

A．The Carnival of Brazil is often held after Easter.
B．The Carnival of Brazil comes from Easter and Saturnalia.
C．The Carnival of Brazil is a festival to regret and begin a new life.
D．The Carnival of Brazil is mainly to celebrate the birth of Christ.
【小題2】How long is the history of the people’s celebrating modern Brazilian Carnival?
A．About 100 years.B．Less than two centuries.
C．About 370 years.D．Over five centuries.
【小題3】Which of the following statements is TRUE about the blocks in Rio de Janeiro?
A．They are always wearing costumes or special T-shirts with themes or logos.
B．They always parade through countryside villages singing and dancing.
C．There are no more than 50 blocks today.
D．They don’t parade before the show.
【小題4】What is the passage mainly about?

I was blind, but I was ashamed of it if it was known. I refused to use a white stick and hated asking for help. After all, I was a teenager girl, and I couldn’t bear people to look at me and think I was not like them. I must have been a terrible danger on the roads, Coming across me wandering through the traffic, motorists probably would have to step rapidly on their brakes. Apart from that, there were all sorts of disasters that used to occur on the way to and from work.
One evening, I got off the bus about halfway home where I had to change buses, and as usual I ran into something,“I’m awfully sorry,”I said and stepped forward only to run into it again.

No one else was there and I had to try to guess if the bus had arrived.

But on this particular evening no one joined me at the stop;It seemed that everyone had suddenly decided not to travel by bus. Of course I heard plenty of buses pass,or I thought I did.But because I had given up stopping them for fear of making a fool of myself,I let them all go by.I stood there alone for half an hour without stopping one.Then I gave up.I decided to walk on to the next stop.

SongKran--Thailand
Dates: 13th-15th, April
In Thailand, it’s time to celebrate the coming monsoon season, which will bring the rain many people have been looking forward to.

Many English learners have difficulty deciding what kind of English accent they want to have． A US accent, perhaps modeled on the way a Hollywood star speaks? Or maybe you want to imitate（模仿） the British accent of a BBC news reader?
Young British people find the US accent attractive while young US people like a British accent． Especially when the person speaking is of the opposite sex(異性)! Let’s listen to what they have to say．
Stephen Yang, 17, from London, UK
A US accent is cute, especially when a girl speaks it． Whether it’s Jessia Alba speaking or the girl- next-door, the way US girls speak has a sweet tingle that is really sassy(時(shí)髦)． A girl from Texas recently moved into our neighborhood． Her Texan twang（鼻音） had all the boys here on their knees within seconds of meeting her．
To me, accents reflect the attitudes, characteristics and lifestyles of the people．
Jennifer Sun, 16, from New Jersey, US
From watching English actors like Daniel Radcliffe, my friends and I have developed a soft spot for British men．Some are attracted to the qualities of English males, while others admire their sense of style．
Everyone, however, agrees that the most appealing aspect of an English man is his accent． For example, many American girls watch Harry Potter movies over and over again just to listen to the actors speak．
The English accent seems almost like art．
【小題1】In Stephen Yang’s opinion, accents just show__________．

A．the beauty of the language
B．how the language is spoken
