Printing images is easy. Just select an image of a purple robot on your PC, for example, and press print. Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot’s 2-D image. “Printing” 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle (喷嘴) releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you.

3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids.

So far, few homes have 3-D printers. That’s because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores (零售商店) plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they’ll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing.

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.

Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?

Point 2 The mobile phone means that we are never alone. “The mobile saved my life,”says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance(救护车) to her rescue.

Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.

Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”

Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously ( 同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access(存取) the Internet, the biggest library on Earth.

1.How do you understand‘Point 1 —The telephone creates the need to communicate, …’?

A. People don’t communicate without telephone.

B. People communicate because of the creating of the telephone.

C. People communicate more since telephone has been created.

D. People communicate more because of more traffic.

2.Which of the following best shows people’s attitude towards mobile phones?

A. Mobile phones help people deal with the emergency.

B. Mobile phones bring convenience as well as little secret to people.

C. Mobile phones are so important and should be encouraged.

D. Mobile phones are part of people’s life.

3.It is possible to talk to several complete strangers simultaneously through _______.

A. the TV screen

B. a fax machine

C. the phone line hooked up to the computer

D. a microphone

4.The best heading for the passage is _________.

A. Phone Power

B. Kinds of Phone

D. Advantage of Phones

Football T-shirts are more commonly connected with boys than girls. This can often cause a problem when you want to find a cool shirt for a girl. That is not to say that there are no cool shirts out there for girls to wear. The problem is that they are often harder to find than the ones for boys.

You can get custom (订制的) shirt printed for girls from a number of custom print stores. Of course you have to make sure that they are legally allowed to use the logos (商标) and colours of the team you want to support.

You can also go through official channels to get the shirt you want. The official channels will generally be the large sportswear stores or the official stores of the teams. These stores will be able to use the colours of the teams and even put the name of the person who the shirt is for on it.

If you do not feel like you have to try the T-shirts on, then an online store may be your best choice. The reason for this is that you can visit various stores and find the best ones.

If you want to see what the T-shirt looks like in real life, then going to a store is the best choice. Large sportswear stores often have football shirts. These are the best places to go if you do not live close to an official store. And these stores usually have lower prices than the official stores.

1.According to the text, football T-shirts ________.

A. are all made by boys

The United States government wants to know what the public thinks about its finding on the safety of cloned animals.

The Food and Drug Administration says meat and milk from clones of adult animals are safe to eat. They called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代)are safe to eat as well.

The United States this year could become the first country to allow the sale of foods from cloned animals. First,however,the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents. The agency says it must receive comments by April 2nd. The F.D.A. seemed ready to act several years ago,but an advisory committee called for more research.

For now,the government will continue to ask producers to honor a request that they do not sell foods from cloned animals.

Clones are still rare. They cost a lot and are difficult to produce. The F.D.A. says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.

Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public know little about cloning. Cloning differs from genetic engineering. A cell taken from a so­called donor animal is grown into an embryo(胚胎)in the laboratory. Next, the embryo is placed into the uterus(子宫)of a female animal. If the process is successful, the pregnancy reaches its full term and a genetic copy of the donor animal is born.

1. From the passage, we know ________.

A. the US government is very cautious about the safety of cloned foods

B. foods from cloned animals are popular in America

C. cloned animals will be easy to produce

D. most foods from cloning are expected to come from clones themselves

2.Who believes that foods from cloning are safe to eat?

A. Most Americans. B. An advisory committee.

C. Critics. D. The F.D.A. .

3. It can be inferred from the last paragraph that _______.

A. cloning has much in common with genetic engineering

B. not every cell taken from a donor animal can grow into a genetic copy

C. the donor animal should be a female one

D. cloned animals grow faster than normal ones

4. Whether the sale of cloned foods is allowed in the US depends on ________.

A. cloning technology

B. the advisory committee’s research

C. public comments

D. the documents of the F.D.A.
