I was blind, but I was ashamed of it if it was known. I refused to use a white stick and hated asking for help. After all, I was a teenager girl, and I couldn’t bear people to look at me and think I was not like them. I must have been a terrible danger on the roads, Coming across me wandering through the traffic, motorists probably would have to step rapidly on their brakes. Apart from that, there were all sorts of disasters that used to occur on the way to and from work.

     One evening, I got off the bus about halfway home where I had to change buses, and as usual I ran into something,“I’m awfully sorry,”I said and stepped forward only to run into it again. When it happened a third time, I realized I had been apologizing to a lamppost. This was just one of the stupid things that constantly happened to me. So I carried on and found the bus stop,which was a request stop, where the bus wouldn’t stop unless passengers wanted to get on or off. No one else was there and I had to try to guess if the bus had arrived.

    Generally in this situation, because I hated showing I was blind by asking for help,I tried to guess at the sound.Sometimes I would stop a big lorry and stand there feeling stupid as it drew away. In the end, I usually managed to swallow my pride and ask someone at the stop for help.

   But on this particular evening no one joined me at the stop;It seemed that everyone had suddenly decided not to travel by bus. Of course I heard plenty of buses pass,or I thought I did.But because I had given up stopping them for fear of making a fool of myself,I let them all go by.I stood there alone for half an hour without stopping one.Then I gave up.I decided to walk on to the next stop.

1.The girl refused to ask for help because she thought_________

2.After the girl got off the bus that evening,she_________.

   A.began to run                    B.hit a person as usual

   C.hit a lamppost by accident         D .was caught by something

3.What was the problem with guessing at the sound to stop a bus?

  A.Other vehicles （车辆）also stopped there.

  B.It was unreliable for making judgments.

  C.More lorries than buses responded to the girl.

  D.It took too much time for the girl to catch the bus.

4.Finally the girl decided to walk to the next stop,hoping__________.

“Now ,”Mrs. Virginia DeView said, smiling, “we are going to discover our professions .”
The class seems to be greatly surprised. Our professions? We were only 13 and 14 years old! The teacher must be _36 _. “Yes, you will all be searching for your future  37 . Each of you will have to   38  someone in your field, plus give an oral report.”
Each day in her class, Virginia DeView reminded us about this. Finally, I picked print journalism. This _39_ I had to go to interview a true-blue newspaper reporter. I was extremely nervous. I sat down in front of him_40_ able to speak. He looked at me and said, “Did you bring a pencil or pen?”
I shook my head.  “How about some   41_ ?” I shook my head again .
Finally , I thought he realized I was   42 , and I got my first big tip as a  43 : “Never,never go anywhere without a pen and paper. You never know what you’ll run into. ”After a few days, I gave my oral report totally from   44  in class. I got an A on the entire project.
Years later, I was in college looking around for a new career, but with no success. Then I _45 _Virginia DeView and my desire at 13 to be a journalist. And I called my parents. They didn’t __46__me. They just reminded me how competitive the field was and   47  all my life I had to run away from competition. This was true. But journalism did something to me; it was in my blood. _48__gave me the freedom to go up to total strangers and ask what was   49 .
For the past 12 years, I’ve had the most satisfying reporting career, __50 __ stories from murders to airplane crashes and   51  choosing my strongest area.  52 _ I went to pick up my phone one day, an incredible wave of memories hit me and I realized that had it not been __53__Virginia DeView, I would not be sitting at that desk.
I get  54  all the time: “How did you pick journalism?”
“Well, you see, there was a teacher…”I just wish I could  55 her.

Life on-line can be a much richer experience when you aren’t restricted to just written words and still pictures.Even if you’re new to the Net,you’ve probably heard about multimedia on-line—listening to audio,watching animations and videos,even playing in three-dimensional space.Sound and movement make information come alive.

To experience it,you’ll need special pieces of software called plug-ins.The term “plug-in” refers to a small,add-on piece of software which extends the capabilities of your web browser,like Netscape Navigator or Microsoft Explorer,turning your computer into a radio or TV.

When you arrive at a web page which contains a file requiring a plug-in which you don’t have,you will usually receive a message asking if you want to get it by downloading it and installing it into your computer.Most of the time,the installation will be automatic.

Occasionally,you’ll run into a downloaded file which needs to be decompressed or un-zipped before installation.Once installed,plug-ins run automatically,without you having to do anything.

Many multimedia controls still need to be obtained from the developer but are installed automatically.

Shockwave is a good example of this.All you need to do is go to the Macromedia site and click on the link to install the ActiveX control.The rest happens automatically.The next time you go to a “Shocked” website,the Shockwave control loads and plays the movie.

Most plug-ins and controls can be downloaded for free on the Internet,although not all will work with every system.Some of them,for instance,only work with Windows 95.

Plug-ins can help us to do all of the following except _________.

A.listening to music

B.watching animations and videos

C.playing three-dimensioned games

D.searching for information on the net

The correct explanation about “plug-in” is _________.

A.a radio or TV connected with a computer

B.a small,add-on piece of hardware which improves your web browser

C.a small,add-on piece of software which can turn your computer into a radio or TV

D.a small,add-on piece of software like Netscape Navigator or Microsoft Explorer

When we go to a “shocked” website a second time,_________.

A.we should go to the Macromedia site and click on the link to install the Active X control

B.the shockwave control loads itself and plays the movie for us

C.we will be asked whether to download the shockwave control or not

D.we have to buy the shockwave control and load it

Most of the time,how can we get a plug-in before automatic installation?

A.We have to buy it from the developer.

B.We have to borrow it from the developer.

C.We have to rent it from the developer.

D.We can obtain from the developer without paying.
