DOGS DRIVE CAR

Auckland, New Zealand

After two months of learning, Monty, and Porter were able to drive an automobile around a racetrack. “We wanted to prove how smart rescue dogs are,”animal behaviorist Mark Vette says. Vette first used voice commands and treats to teach the dogs how to turn a steering wheel and how to change gear (換擋).

The dogs’ ride only accelerated up to 7.5 miles an hour, and trainers could stop the auto using a remote control.

GOLDEN ZEBRA

Kailua-Kona, Hawaii

Zoe the zebra’s markings are special. The animal has white and golden stripes. Zoe’s appearance resulted from a rare condition called amelanosis (黑素缺失癥). Her body doesn’t make enough melanin, the substance in an animal’s skin and hair cells that produces color. “Only 25 other golden zebras are known to exist in the world,” says Ann Goody, who runs the wildlife refuge where Zoe lives. In the wild, life may be difficult for animals with amelanosis because predators (捕獵者) can easily spot them. But Zoe is protected at her refuge.

COCKATOO MAKES TOOLS

Vienna, Austria

When Figaro the cockatoo spots food lying just out of reach from his cage, he builds a tiny wooden tool to sweep the tasty prize in his way.

The bird first revealed his talent when a stone he was playing with rolled out of his cage. The cockatoo couldn’t reach the stone. So he flew away and returned with a small branch, slipping it through the fence to slide the stone toward him.

Wondering if he would do it again, scientists placed a nut exactly where the stone had been. This time, Figaro pulled out a small piece of wood in his cage and dragged the nut toward him.

1.If Zoe the zebra is set free in the wild, she will ________.

A. meet no natural predators

B. not get along with other zebras

C. manage to make enough melanin

D. be easily found for her appearance

2.What’s special about Figaro the cockatoo?

A. He is particular about his food.

B. He is extremely fond of stones.

C. He is good at drawing support from outside forces.

D. He can tell the difference between stones and nuts.

3.What is the text mainly about?

A. Amazing animals.

B. Ways to help animals.

C. Animals’ unique talents.

D. Tips on training animals.

During a career planning class, Brenda Fabian asked how many students use Facebook, a popular online networking community for college students. Almost everyone in the room raised a hand.“Then I asked how many knew that employers are reviewing Facebook for hiring purposes，”says Fabian，director for Center for Career Services at Susquehanna University.“No hands were raised, and their faces revealed the students' surprise.”

Although some parents do keep track of their teen's online activities，most teenagers don't realize that websites may be monitored by schools，prospective(未來的) employers or anyone else who might be interested in the teenager's lifestyle not just today but anytime in the future.

Most of us don't realize that the information that gets posted on the Internet may be deleted，but it doesn't disappear permanently.“The stuff is there forever，”says Jamie Riehle，director of Web Publishing at Lycos.“It is backed up (備份) on servers and doesn't go away.”

As company recruiters，college admission officers，law enforcement personnel and parents become more Web savvy (有見識的)，it becomes even more vital for teenagers to be cautious when posting any information on their websites. Even though sites that are private can be seen only by a preselected list of friends，there are companies that，for a fee，can dig deeper into cyberspace(網(wǎng)絡(luò)空間) and find anything. Even government officials who thought that deleting email would exonerate(宣布……無罪) them from wrongdoing are discovering that，on the Web，there is no such thing as private or gone forever.

Steven Rothenberg，president and founder of College-Recruiter.com，suggests that teenagers think of their Web posts as tattoos（紋身）. “Inherently(內(nèi)在地)，there is nothing wrong with them if they are private，”he says.“But if they are visible or offensive, it can affect the way others see you.”

1.The information posted on the Internet ________.

A．can be deleted easily

B．can't be deleted completely

C．usually falls in the hands of employers

D．remains for a long time

2.What do we know about sites that are private?

A．They are owned by some companies.

B．They charge people for viewing them.

C．They can keep the information a secret.

D．They are not so private as supposed.

3.The second paragraph implies that ________.

A．one who posts negative things may have their employment affected

B．a(chǎn) teenager should not write about his lifestyle online

C．it's hard for parents to keep track of their teen's online activities

D．the Internet is becoming more insecure

4.Steven Rothenberg believes that ________.

A．teenagers should not be allowed to post anything online

B．teenagers should keep their information private online

C．teenagers should be cautious about their posts online

D．teenagers should be monitored online

See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer. You might find it hard to believe that you could actually “print” an object like you would draw a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.

Instead of ink, the materials the 3D printer uses are mainly plastic, resin(樹脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.

Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20,000, while now they cost only about ￡1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes, bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.

However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

1.According to the article, in the future, the 3D printing technology will _______.

A. enable people to make better purchases online

B. change the way we make many products

C. be applied as widely in our daily life as computers

D. shorten the time it takes for people to get what they buy online

2.What happened in the 3D printing industry last year?

A. The 3D printing technology was taken out of the factory.

B. The 3D printing technology began to be used in various fields.

C. The 3D printer was used for medical treatment for the first time.

D. The 3D printer became more affordable for consumers(消費者).

3.What is the best title of the passage?

A. Great Demand for 3D Printers

B. Technology in the Future

C. Online Shopping Disappearing

D. Printing out Everything

4.How is the last paragraph developed?

A. By giving examples.

B. By making comparisons.

C. By analyzing the cause and effect.

D. By using figures.
