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 they let in and out. For example, if we inject protein or DNA directly into the body, our immune (免疫的) 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.
A 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 layer of skin on top of the plastic.
The plastic feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection.What would be the best title for the text?

| B．The plastic skin will remain a part of the new skin. |
| C．Plastic blood will take the place of real blood. |
| D．The cells of our body will let in whatever molecules they get. |
One-hundred-and seventh birthdays aren’t usually celebrated for authors who aren’t alive anymore. But Theodor Seuss Geisel---better known as the children’s books author Dr. Seuss ---who came into the world on 2 March, 1904, was an unusual man.
Like generations of children I was raised on his wonderful stories. But when I now read them to my children it’s not just the childhood memories I enjoy. His writing is brilliant and imaginative and flows with a self-confidence as sure as the words of a Shakespeare poem. Readers ride his characteristic rhythm (韵律) with an effortless joy that cannot be matched by any other modern writer:
You have brains in your head
You have feet in your shoes
You can steer yourself any direction you choose
And will you succeed?
Yes indeed, yes indeed!
Ninety-eight and three-quarters percent guaranteed.
Seuss’s brilliant cartoons and clever words make his books a delight for adults but they attract mostly children of course. His stories teach kids moral lessons but in indirect and entertaining ways.
The first Seuss book I was given was The Lorax, written just as the 60s were becoming the 70s. Seuss was ahead of his time, and in this book the dawn of concern for environmental problems are shown as the Lorax “who speaks for the trees” battles against an evil businessman who wants to destroy the forest and make goods “which everyone needs”.
It’s not only a warning of the heavy price of environmental destruction, written well before most people had thought to worry, but it’s also a smart analysis of consumer societies: “Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not.” This is of course a moral message, but not of the kind designed to persuade the youngsters into behavior that adults want.
I could go on, but hey, it’s a birthday, and I’m sure you folks have some good toasts to raise for the party…What’s the purpose of this passage?

Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation. It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York，So I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made living looking for the best deals and exposing （揭露）the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money’s worth. I’m also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.Why did Delta give the author's family credits?
| A．They took a later flight. |
| B．They had early bookings. |
| C．Their flight had been delayed. |
| D．Their flight had been cancelled. |
What can we learn about the author?
| A．She rarely misses a good deal. |
| B．She seldom makes a compromise. |
| C．She is very strict with her children. |
| D．She is interested in cheap products. |
What does the author do?

| C．She's a media person. | D．She's a businesswoman. |

They tell us that the earth travels over a thousand miles a minute on its journey round the sun.
The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the moon but we know that no one can ever go to the sun. It is far too hot for people to live anywhere near it. The sun is three hundred thousand times heavier than the earth and more than million times larger.A long time ago, people said the sun was ____.
