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.
【小题1】Why is a microblog different from a traditional blog?

B.Because a microblog doesn’t include videos, but a traditional blog does.
C.Because a microblog has smaller contents than a traditional blog in actual and total file size.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.

Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.

The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr. Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents.  " Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends," he says.

If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use.  Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child’s physical, sensory, communicational and social development.Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten.

There are good reasons for the government to push early childhood education.Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life.Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in   

Special Education classes, and are less likely to receive public help or go to jail.

There are also negative parts to putting a child in formal education programs too early.Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work.” I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school.Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier.

Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years.It seems that environment is a bigger factor on life’s success than early education.Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children.Perhaps it is time to find other ways to close that gap.

1.The purpose of the government valuing the early childhood education is ________.

    A.to develop the children’s communication

    A.to give orphaned children good care and education

    C.to get the children prepared for the kindergarten

    D.to train the children formally and regularly

2.According to the studies, which of the following is True?

    A.Children with good early education may have a rich life.

    B.The orphaned children are usually unhappy in their life.

    C.Children without early education can do well at school.

    D.Head Start programs are helpful to the poor children.

3. The author’s attitude toward the early childhood education is _________.

    A.puzzling     B.objective   C.indifferent   D.approving

4.The main idea of the last passage is that __________.

    A.the early childhood education is very necessary

    B.Head Start programs have helped the children a lot

    C.environment is the most important to life’s success

    D.better ways should be found to help the poor children

         A new study by a Penn State College of Medicine research team found that honey is a better and safer treatment for children than cough medicines.   

         Ian Paul, the study’s lead researcher, was motivated to test honey because treating coughs in children has recently become a sticky subject. Coughing is the body’s way of clearing irritated (受刺激的) airways to help you breathe. But too much coughing can irritate your lungs and throat even more. It can also make it tough to get the sleep your body needs to heal. Hoping to ease the suffering of their children, parents often give them cough medicines.  

         But there have never been any good studies showing that they work. Cough and cold medicines may also cause serious side effects. Hundreds of kids die in the hospital each year after receiving too much cough medicine by mistake. Last October, the US Food and Drug Administration suggested that parents should not give cough medicines to children under 6.

         In order to search for a different solution, Paul designed a study that involved 105 kids who were sick with coughs and other cold conditions. At bedtime, the kids took buckwheat (荞麦) honey, honey-flavored (蜂蜜味的) DM (one of the most common ingredients in cough medicines), or no treatment. Parents and kids in the no-

-treatment group knew they weren’t getting anything, but the other two groups weren’t told which treatment they were getting.

         The surveys showed that kids who swallowed about 2 teaspoons of buckwheat honey before bedtime coughed less and slept better than kids in the other groups. “When parents want something for their kids to take,” Paul says, “honey seems like the best option”.

         But what gives honey its healing power? Substances called antioxidants (抗氧化剂) may be part of the answer. All honey contains antioxidants that protect our cells from damage. Studies show that antioxidant levels in the body rise after someone swallows honey.

68. Which of the following can be the best title for this passage?

A. No cough medicines to children    

B. Sweet solution to kids’ coughing

C. Best treatment for your cold   

D. Cough medicines don’t work  

69. We can learn from Paragraph 2 that coughing ______.

A. sometimes does good to people 

B. can cure lung and throat diseases

C. is more harmful to children  

D. helps improve children’s diet   

70. During Paul’s experiment, the kids who received treatment ______.

A. seemed much worse than before 

B. knew they weren’t getting anything 

C. coughed less and slept better

D. had no idea what they swallowed
