　　Until recently the chances for criminal activity(犯罪活动)on the Internet have been low．However, business done on the Internet is growing rapidly, as people order books and other products and make money transactions(交易)．All this is a strong temptation(诱惑)for hackers．

　　Hackers are often young people who are deeply attractedby computers．They use them to prowl the Internet, looking for ways to break into computer systems(系统)run by banks, telephone companies and even government departments．They look for examples of credit cards(信用卡)and try to steal the numbers．

　　Recently in America, hackers have been caught testing the security(安全)system at the Pentagon, headquarter(总部)of the American Defence Department．But still the backers insist often for a dare “because it’s there” although with what success nobody really knows．

　　Hackers seldom admit to(享有)a successful break in．The first sign of a security breach(泄密)may be when a customer discovers fraudulent(欺骗)money transaction on a credit card account(账户), and it is hard to discover it．

　　“You just don’t give your credit card out to anybody, ”says Michael White, multimedia product manager for clear communications, “and in the same way you should regularly change your credit card entering number, you can defeat hackers by regularly changing your　Internet password(密码)．If you don’t, it’s like leaving the bank vault(金库)door wide open．”

　　The warning against hackers is out there, and the answer is obviously to choose tricky passwords and change them frequently and to watch who you pass your credit card details to．

(1)

We can learn from the text that hackers _________．
[　　]
A．	are computer fans and play tricks on people on the Internet
B．	steal only credit cards on the Internet
C．	are mostly young computer fans
D．	regularly attack the computer systems

(2)

“Prowl” used in the second paragraph means _________．
[　　]
A．	move quietly
B．	destroy
C．	get information
D．	rebuild

(3)

Hackers seldom admit to a successful break in because _________．
[　　]
A．	they are not easily caught by policemen
B．	they regularly change their Internet password
C．	it’s hard for them to get the information of the credit card account
D．	they can’t easily get the customers’ Internet passwords

In the computer age, most of us take a broadband（宽带）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files（档案文件）download much faster than ten years ago. And the files are much bigger too.

There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.

Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs（郊区）, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.

But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.

Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.

Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.

1.The underlined part “a catch” (in Paragraph 2) probably means “_____”.

A．a rare challenge B．a desirable plan

C．an efficient device D．a hidden problem

2.What can we know from the third paragraph?

A．Internet connection has not been popular in most cities.

B．Internet service providers care about rural（农村的）customers.

C．Computer is popular in developing countries.

D．It is hard to bring Internet access to users in remote areas.

3.Paragraph 4 mainly tells us that technological advancements _____.

A．make TV and telephone available everywhere

B．bring great change to people’s everyday life

C．make it possible for more people to use the Internet

D．bring faster Internet connections to users

4.What may eventually settle the “last mile” problem?

A．The broadband connection’s getting faster.

B．More and more Internet users.

C．more and more Internet connections.

D．The rapid progress in cell phone technology.

根据对话情景和内容，从对话后的选项中选出能入空白处的最佳选项。选项中有两项为多余选项。

We’ve all got a lot going on in our lives. Some things are fun, some aren’t. I think I’ m a fairly positive person. 1 In fact, being positive means different things to different people. 2

Focus on what you have not what you don’t. It’s impossible for one to have all the nice things in the world. Focus on what you already have. This can create feelings of happiness.

3 If you can express thanks for everything you have, you leave little room for bad thoughts. It’s a great practice. When you focus on what really matters, so many worries go away.

Forget the past and don’t cling to(紧紧抓住) the future: 4 If you cannot forget mistakes and missed opportunities from the past, you probably find you blame yourself all the time. Clinging to the future is a bad one, too. It truly may never happen. So pay more attention to the present .

5 It always makes me wonder what people are saying about me if they speak so ill of someone else when they aren’t around. If you don’t do this, you never have to worry about what you’ve said getting back to someone.

A． Be grateful.

B．Here are a few key ways to being positive that have really helped me.

C．Speak about others as if they were in front of you.

D．The past will never come again.

E．Being positive doesn’t mean smiling a fake smile all the time.

F．The past has happened and the future may never come.

G．Have fun and hug yourself.
