The deadliest Ebola outbreak in history that has so far killed almost 1000 people in Guinea, Liberia, Sierra Leone and Nigeria in West Africa has caused fear around the world.

The outbreak is unprecedented（空前的）both in infection numbers and in geographic scope. Officials from the World Health Organization (WHO) said earlier this month the outbreak “is moving faster than our efforts to control it”, reported CNN. So far, the battle against the virus doesn’t appear to be slowing down.

The Ebola virus is terrifying no matter where it strikes: It’s a disease with no cure that causes headaches and fever, severe diarrhea(腹瀉), vomiting and bleeding and has been known to kill up to 90 percent of its victims.

It is understandable for people to be panicked, but those living outside Africa shouldn’t be particularly concerned about contracting the virus, says a Washington Post article.

This is because transmission of Ebola requires direct contact with an infected person’s blood, vomit or other bodily fluids during the period that he or she is contagious(接觸傳染的). It is something that is extremely unlikely for anyone but healthcare workers. The virus is not spread by coughing or sneezing.

Media outlets in the US and the UK are using terrifying headlines, wrongly claiming that people infected with the virus have traveled to their countries.

James Ball at The Guardian says the Ebola outbreak in Africa is tragic, but it is important to keep a sense of proportion. Other infectious diseases, including common influenza, are far, far deadlier.

1.What does the author say about the Ebola outbreak in West Africa?

A. It has caused thousands of African deaths.

B. Its spreading speed is beyond people's imagination.

C. It has already traveled to the US and the UK.

D. The fight against it is slowing down.

2.The Ebola virus is terrifying because ________.

A. it cannot be cured at the moment

B. it is easily infected

C. it spreads faster than any other infectious disease

D. it has caused more deaths than other infectious diseases

3.The underlined phrase in the last paragraph means

A. keep a secretB. stay calm

C. keep silentD. stay away from it

4.What is the author's attitude towards people's panic?

A. Objective.B. Supportive.C. Doubtful.D. Understandable.

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(fèi)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.
