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(未来的) 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 (备份) on servers and doesn't go away.”

As company recruiters，college admission officers，law enforcement personnel and parents become more Web savvy (有见识的)，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(网络空间) and find anything. Even government officials who thought that deleting email would exonerate(宣布……无罪) 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（纹身）. “Inherently(内在地)，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 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

After Steve Jobs died，his friend Larry Ellison said something like this, “There will never

be another Steve Jobs”. 1. Larry wrote this list of Steve's life lessons to remind us all.

1. Love what you do. Sure Steve became a billionaire when he brought Apple back. Apple was his calling even after he got fired from the company. We all have bad jobs at one point in our lives. But the question is: am I in the right job? Have I found the right company? Life doesn’t go on forever. 2.

2. Don't do it all by yourself.

Steve learned a great leader can't do it all by himself. He needs people. They must be talented. 3._ They must be given the opportunity to succeed and fail. In short，we have to learn to be a great leader if we want to see our great ideas and hard work truly have an influence on the world.

3. 4._

Apple is always good at creating a new product that meets the exact needs of users. It’s empathy（共鸣）that helps Apple achieve this. Whenever the user has the first touch with a new Apple product，he says "Wow，it's just what I need". Remember, you're King in the business world if you know exactly what consumers desire.

4. Don't mess around with your health.

5._ That's the most important lesson from Steve's life. It's great to learn from him but，the fact is he should still be here if he had treated his cancer properly. Instead, Steve chose a naturopathic(自然疗法)solution that wasn't effective. When he finally decided to take his doctor's original advice，it was too late.

A. What are the key things that we could learn from him?

B. Get on our right path now.

C. Will this lead to a successful career?

D. They must be inspired.

E. Put yourself in the other person's shoes.

F. Take your health seriously.

G. Be the best in your field.

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(腹泻), 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(接触传染的). 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.

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 (换挡).

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 (黑素缺失症). 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 (捕猎者) 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.
