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. 小题1:Plug-ins can help us to do all of the following except _____.

D．a small,add-on piece of software like Netscape Navigator or Microsoft Explorer小题3: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小题4:Most of the time,how can we get a plug-in before automatic installation？

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.

Time is very important in our lives. It  16  our everybody moments. However, time never had any  17  in my life until I received a watch from my father that organized my life and made me more  18 .
It’s round in the center with two silver bands that go around my wrist. And all of it is made of silver. This  19  tells me the importance of time in my life.
I received this  20  on a gray-sky day. I had to go to the airport at 9:00 am to  21  up my uncle Ali and take him to my father’s house  22  , I was late because I was  23  out with my friends. Later on that day, around 11:00 am, I  24  my uncle, but I was very 25  for him. He had  26  the airport and taken a taxi to my father’s house.
I got to my father’s house at 2:00 pm on the same day and looking at my angry father’s face I felt 27  of myself at that moment. After I said hi to my  28  father and tired uncle, my father asked me to sit next to him where he handed me this watch as a gift from him. Then he said, “Essa, did you have  29  with your friends today？” I answered, “Yes, father, and I’m sorry about not picking up my uncle Ali.” He said, “What you  30  was not very nice and you should be sorry for your  31  .” I was ashamed and said, “Father, I’ll never do it again, I promise.” He said, “I hope today you learned something important, and this watch will be a  32  for you.” He told me to take this watch and use it as an organizer of my 33 .
I learned a very important lesson from my father: to  34  time and never be late to get someone. This watch is  35  to me, not because of its price, but because of the lesson that I learned from it.

Interview With God I dreamed I had an interview with God.“So you would like to interview me？”God asked.“If you have the time,”I said.“My time is eternity.”God smiled,“what questions do you have in mind for me？”“What surprises you most about humankind？”God answered,“That they get bored with childhood,they rush to grow up,and then long to be children again.That they lose their health to make money... and then lose their money to restore their health.That by thinking anxiously about the future,they forget the present,such that they live in neither the present nor the future.That they live as if they will never die,and die as though they had never lived.”God’s hand took mine and we were silent for a while.And then I asked,“As a parent,what are some of life’s lessons you want your children to learn？To learn they cannot make anyone love them.All they can do is to let themselves be loved.To learn that it is not good to compare themselves to others.To learn to forgive by practicing forgiveness.To learn that it only takes a few seconds to open profound wounds in those they love,and it can take many years to heal them.To learn that a rich person is not one who has the most,but is one who needs the least.To learn that there are people who love them dearly,but simply have not yet learned how to express or show their feelings.To learn that two people can look at the same thing and see it differently.To learn that it is not enough that they forgive one another,but they must also forgive themselves.”“Thank you for your time,”I said humbly.“Is there anything else you would like your children to know？”God smiled and said;“Just know that I am here always.” 小题1:.In answering how many questions did God give “me” his opinion？
