Since its invention 100 years ago, plastic , the superstar of the technological age, has become ugly and ungreen . But that’s about to change. An exhibition at London’s Science Museum this week could put it back on the cutting edge of science.
Have you ever hesitated in donating blood? The invention of “plastic blood” might make you feel better.
British scientists are working on the artificial blood as a replacement for real blood in emergency situations. It is made of plastic molecules(分子 ) and can join oxygen and transport it around the body. As a red, honey-like glue , plastic blood can be carried around conveniently . You just add water to make as much blood as you need.
The cells  of our body are strict about what molecules the let in and out . For example , if we inject protein or DNA  directly into the body, our immune ( 免疫 ) SYSTEM WILL DESTROY IT BEFORE IT REACHES THE CELLS.
To get around this , a British scientist has created drug-carrying plastic balls that fool the body into thinking they are natural. Once inside the cell, their contents are spread out through a small controlled explosion.
Skin transplants  are widely done these days. But removing a piece of skin from, say , the bottom to plant it on the face  can hurt and be troublesome.
The British company, Celltran, is working on plastic skin. Using plastic, they plan to take a small piece of the patient’s skin and grow it into an extra lay of skin on top of the plastic. a
The plastic  feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection .

The sun was just coming up when I headed out to work last May at 6 a.m. Not quite dark but dark enough to need my headlights. I turned onto one of the lonely rural country roads.

Maybe it was because I was listening to the radio, maybe it was because I was already thinking about some projects at work, that I didn’t spot the dark object on the road until I was too late. I ran over it and felt the back left tire pull, and then sink. I stopped and got out of the car.

No mystery here---- my back left tyre was cut like a loaf of bread. Back 50 yards was a piece of sharp iron I had run over. I had never changed a tyre. I looked up the road. Not a car in either direction. The nearest service station was miles away. I threw up my hands. Then I remembered---- my cell phone! I powered it up before realizing, I didn’t know who to call.

Wouldn’t you know it, I spotted a car coming from the opposite direction. The driver slowed as he approached. I guessed he could see I was in trouble. He stopped his car, got out and immediately saw the trouble. “Madam, would you like me to change that tyre for you?” he asked. The man couldn’t have been more friendly. I was frightened out there and he put me completely at ease. “There,” he said, after putting on the spare, “you are all set to go.”

“Good thing for me that you were driving this way,” I told him, as I climbed back into my car.

“Funny you should say that,” he said. “Just like you, I was heading to work, but my job is in the opposite direction. I made a wrong turn at some point. I don’t know what I was thinking.”

A. He stopped and laughed at her.

B. He walked over to frighten her.

C. He helped her without hesitation.

D. He drove away in the opposite direction.

4.The end of the story tells us that the man ______.

A. went a wrong way                       B. felt the writer funny

C. didn’t know what he was doing     D. come specially to help the writer

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?

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.
【小题1】From the first two paragraphs, we can know                   ．

Getting your teen to think beyond his own immediate needs can be more difficult than cracking a nut with a plastic fork．But don't worry．It's not impossible．There are many ways to encourage your teen to care about those outside his immediate circle of friends．As he begins to have responsibility towards others, he will realize he feels even better about himself．
"Teens are thinking about career, college, and what their future might look like," explains Michelle Maidenberg, a clinical director of Westchester Group Works, a center for group treatment in New York．"This is very challenging and just one of the reasons why they are so focused on their own world．" Once teens participate in community service, however, they begin to look beyond their personal needs．They also learn firsthand about the challenges others face, and they experience a sense of authority as they realize they can make a real difference in others' lives．
Not sure how to convince a teen to get away from the cell phone and into a community project? Teens buy into community service when the project or program is in an area of their interest．
"Finding something in an area of interest for them keeps them motivated and inspired," Maidenberg says．For instance, if he is interested in culinary （烹饪） school, he could volunteer in a soup kitchen or bake for a project that supports families in need．Volunteer projects in your teen's area of interest will build her knowledge base as well as help others．
Parents can do their part by participating in community service themselves．Teens can learn directly from their parents that personal enjoyment is not ,all that matters．
Let teens know the benefits they will obtain．“Give them every reason in the world to volunteer," Maidenberg advises．She says that working on community service projects builds confidence．"By working with others, teens improve managerial, interpersonal and communication skills．Community service helps to approach maturity when they take a step back to see the needs of other people," she adds．Another reward: service hours look great on a resume!
