It's not a new phenomenon, but have you noticed how many nouns are being used as verbs? We all use them, often without noticing what we're doing.

I was arranging to meet someone for dinner last week, and I said “I’ll pencil it in my diary”, and my friend said “You can ink it in”, meaning that it was a firm arrangement not a tentative one!

Many of these new verbs are linked to new technology. An obvious example is the word fax, which is a shortening of facsimile originally, an exact copy of a book or document. We all got used to sending and receiving faxes, and then soon started talking about faxing something and promising we'd fax it immediately. So, nouns turn into verbs in two easy stages. Then along came email, and we were soon all emailing each other madly. How did we do without it? I can hardly imagine life without my daily emails.

Email reminds me, of course, of my computer and its software, which has produced another couple of new verbs. On my computer I can bookmark those pages from the World Wide Web that I think I'll want to look at again, thus saving all the effort of remembering their addresses and calling them up from scratch. I can do the same thing on my PC, but there I don't bookmark; I favorite—coming from “favorite pages”, so the verb is derived from an adjective not a noun. I wasn’t really sure whether people said this, but someone told me recently that they had favorited a site I was looking for and so they could easily give me its address.

In the late 1980s I noticed that lots of my friends had acquired pagers, and kept saying things like “I’ll page you as soon as I know what time we’re meeting”. They couldn't say it to me, though; I refused to have one. So my children bought me a mobile phone, now known simply as a mobile and I had to learn yet more new verbs. I can message someone, that is, I can leave a message （either spoken or written）for them on their phone．Or I can text them, write a few words suggesting when and where to meet, for example. How long will it be before I can mobile them, that is, phone them using my mobile? I haven’t heard that verb yet, but I’m sure I will soon. Perhaps I’ll start using it myself!

The science of physics today is as current as the morning newspaper. Indeed,as

a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants, the world ?itself? has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.

Clearly, every grown?up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美国国会) voting huge sums of money for new ?warships,? space exploration, or atomic energy；the office staff learning to use a new computer；son Bobby wanting to know about going to the moon；or the housewife learning to operate a new electric stove physics seems to be everywhere.

Teachers in thousands of schoolrooms in America are trying to communicate some of the excitement and importance of these new developments to their students.

 They know that some of their eager students will someday be scientists and will them selves then contribute(贡献) to the development of new knowledge or its application to new things.

But in any case, they can be sure that if they bring a knowledge of science(any science) to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.

Before astronauts can go into space, they have to have the right suit. That’s why NASA（美国国家航天和航空局）scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(灵活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.

Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.

“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.

Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.

These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.

What characteristic does the new space suit have?

A. The new space suit will need much maintenance.

B. The new space suit will be heavier than before.

C. The new space suit will have less mobility than before.

D. The new suit will use new technology to help astronauts be safe in outer space.

What’s the disadvantage of the Russian space suit?

A. The Russian space suit is big and massive.

B. The Russian space suit is much complicated.

C. The Russian space suit is merely used a few times.

D. The Russian space suit is easy to work in for long periods of time.

The underlined word “shield” in the third paragraph might mean_______.

A. harm          B. protect        C. help           D. warn

Why can scientists test the design out before actually making the new space suits?

A. Because designing the new space suit is not a complex task.

B. Because computers are being used to help scientists design the new space suits.

C. Because it needs little knowledge to design the new space suits.

D. Because the scientists only change the old space suits a little and make them into the new ones.

How long will it take scientists to put the new space suits from prototypes into the first practical use?

A. Two years.     B. Three years.     C. Four years.     D. Six years.

DNA ( Deoxyribonucleic acid ) is one of the most important discoveries in science. DNA is the plan for the human being , as a blueprint is the plan for building. DNA makes a person look the way he does. A  person's  DNA. comes  from a mixing of his parents' DNA. That's why a child looks like his parents. But, besides controlling things such as height and hair color, DNA can also give people diseases , Scientists are now studying DNA to cure diseases.

In the seventies, scientists developed a process called recombinant (重新组合) or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In so doing, scientists can better understand DNA, especially what parts of DNA do . After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure.

Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans, because they take CO₂, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too, but do if much faster. As things such as cars and factories have already put much CO₂ in the area, “super-trees” are badly needed.

Unfortunately, there is serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.

As a result, RDNA research will create many solutions (解决方案), but it will also create many problems.

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals, ” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.

It’s not just that we’re going to where the animals are, we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.

“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But some strains (变异体) may become harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.

We learn from Paragraph 1 that the pet sold at the shop may ________.

A. come from Columbia

B. enjoy being with children

C. prevent us from being infected

D. suffer from monkey-pox

Why did Isaksen advise people not to have foreign pets?

A. They attack human beings.

B. We need to study native animals.

C. They can’t live out of the rain forest.

D. We do not know much about them yet.

What does the phrase “the wake-up call ” in Paragraph 3 most probably mean?

    A. a new disease

    B. a clear warning

    C. a dangerous call

    D. a morning call

The text suggests that in the future we_____.

    A. may have to fight against more new diseases

B. may easily get infected by diseases from dogs.

C. should not be allowed to have pets

D. should stop buying pets form Africa.
