              In our life,we have rarely expressed our gratitude to the ones who have lived those years with us.In fact,we donˈt have to wait for  (1)  to thank the ones closest to us—the ones so easily  (2)  .If I have learned anything about giving thanks,it is this:Give it now!

                (3)  your feeling of appreciation is alive and sincere,act on it.Saying thanks is such an easy way to  (4)  the worldˈs happiness.

              Saying thanks not only  (5)  someone elseˈs world,but brightens yours.If youˈre feeling  (6)  ,unloved or unappreciated,try reaching out to others.It may be just the  (7)  you need.

              Of course,there are times when you canˈt express gratitude  (8)  .In that case donˈt let embarrassment sink you into silence—speak up the first time you have the chance.

              Once a young minister,Mark Brian,was sent to a  (9)  town of Kwakiutl Indians in British Columbia.The Indians,he had been told,did not have a  (10)  for thank-you.But Brian soon found that these people had   (11)  generosity.Instead of saying thanks,it is their custom to  (12)  every favor with a favor of their own,and every kindness with an equal or superior  (13)  .They do their thanks.

              I wonder if we had words in our   (14)   for thankyou.Would we do a better job of  (15)   our gratitude?Would we be more responsive,more sensitive,more caring?

              Thankfulness sets in motion a chain reaction that  (16)  people all around us—including ourselves.For no one ever  (17)  the tune of a grateful heart.Its message is   (18)  ;its words go  (19)  all earthly barriers;its music   (20)   the heavens.

              TIANJIN, Feb. 6 - The computer viruses known as "Kompu" and "Happytime" will attack China next week, but damage will be limited, predicted the Tianjin-based National Computer Virus Emergency Response Center on Sunday.

              The center - the only anti-virus products testing and certification center authorized by the Chinese Ministry of Public Security - raised the alert about the two viruses, which are expected to hit the country from Feb. 6 to 12.

              The experts explained that the Wm_Kumpu virus originated in Estonia and appears on the computer screens with the messages "Mul on paha tuju!" and "Tahan kommi", which mean "I am in bad mood" and "Give me some candy".

              The Vbs_Happytime, a virus in e-mail attachments, can eliminate.exe and .dll files in the computer hard disks.

              Experts warned computer users who may log on to the Internet to receive mail or visit Internet chat rooms when they finish the week-long Spring Festival vacation and return to work on Monday.

              The center advised computer system maintenance technicians to scrutinize their systems and upgrade anti-viral software as precautions against the viruses, before the routine working week starts on Monday.

              Experts with the center said that there is no need to immediately format computer hard drives stricken with the viruses, since the viruses can not possibly damage all data on the hard disk in a short period of time. Computer users can use software and tools to restore the lost data.


              (1) Which statement is WRONG according to the passage?
              A. There is no need to immediately format computer hard drives stricken with the viruses.
              B. Computer users should be careful when they receive mail or visit Internet chat rooms.
              C. The Wm_Kumpu virus is a virus in e-mail attachments.
              D. It is impossible for the viruses to damage all data on the hard disk in a short period of time.
              (2) Where do you think the passage is from?
              A. textbook B. newspaper C. magazine D. computer book
              (3) What is the meaning of the underlined word eliminate ?
              A. remove B. save up C. keep D. use up
              (4) Which is the best title for the passage?
              A. Warning
              B. Don’t turn on your computer
              C. Vbs Happytime is On the Way
              D. Computer viruses to hit China next week

              One day I was driven by a rainstorm to take shelter in a little hut by the roadside, which was  (1)  by a shoemaker as his workshop. The man and his son were  (2)  at their work, and  (3)  saying, “Good day,” we began to talk together. 

              Before I had been with them long, the old man  (4)  his son out to get something that he  (5) for his work. The boy was only five minutes  (6) , but it was too  (7)  for the active old shoemaker. He became  (8) , moved about the room, and  (9) took up a piece of leather and fell to  (10)  it, saying, “You know, sir, it will never do to be idle.” 

              As soon as the rain was over, I went on my way home,  (11)  what I had heard—“It will never do to be idle.” Some people are  (12) idle; others are idle only now and then. I was one of the latter class. I could work only  (13) . So the old man's words came home to me. They awakened my  (14), and I begin to feel how wrong it was to (15)  so much of my life in idleness. 

              I had often heard and read that  (16)  is a very great evil, but now I began to see that it  (17)  far more sorrow than people are  (18). It is the man who is doing nothing that is drawn into disaster, while the busy man is  (19) . It is only the idle that are unhappy. So I made up my mind to  (20)  the shoemaker's rule for the rest of my life.

              At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time.

              The   (5)  of “a body clock” should not be too  (6)  since the lives of most living things are controlled  (7)   the 24 hour night-and-day cycle. We feel  (8)  and fall asleep at night and become   (9)  and energetic during the day. If the 24 hour-cycle is  (10)  , most people experience unpleasant  (11)   . For example, people who are not  (12)   to working at night can find that  (13)   of sleep causes them to  (14)  badly at work.

              She handed me a fivedollar bill through the car window,then turned and walked away.I didn't know her name,nor where she was going,but I knew I will never forget that stranger who generously saved me from a lot of frustration(挫折) and walking a mile or more to my destination.
              That day my husband,Leo,and I were already half an hour late for an important conference.We had taken the wrong fork in the expressway,and found ourselves stuck in traffic that was blocked for four miles due to a serious accident.
              When we finally were able to exit,we tried to find parking lots near the hosting hotel.But they were all full.Plus neither of us had brought change and all we had was a twentydollar bill.When we did find some space in a lot two blocks away from the conference,we were unable to pay the automatic(自动的) box for parking.So we needed five dollars.
              We asked several people approaching the pay box if they could change a twenty."No","No"were their answers.So,dejected,we walked back to our car,got inside,and started to back out.We were going to look for other parking spots on the street,which would surely have taken us a longer distance away.
              Just then,one of the people we had spoken with tapped on the window on the passenger side.It was a medium built woman,who was all bundled up in jacket and scarf,wearing jeans and boots.Surprised,I was reluctant,at first,to roll the window down.What could she possibly want?I lowered the window just enough to hear what the woman had to say.Through the window,she showed a fivedollar bill."I don't have change,"she said,"but here is an extra fivedollar bill.Use it to pay for your parking spot."
              I was floored!Was this woman,whom I'd never seen before,actually giving me this much money?Yes,that was exactly what she was doing!She wouldn't take the check I offered her for the cash.She just walked away.

              It's great fun to explore new places,and it may be like an adventure,even when you know you're not the first to have been there.But to make sure not to get lost or waste time going round in circles,the following tips may be helpful.
              •Do the map reading if you're being driven somewhere.It'll be easier if you keep the map following the direction you're traveling in.Keep looking ahead so that you can give the driver lots of warning before having to make a turn or you'll have to move to the back seat.
              •Get a group of friends together and go exploring.You'll need a good map,a compass,a raincoat,a cell phone to call for help in case you get lost,and a bit of spare cash for emergencies.Tell someone where you're going before you set out and let him know what time you expect to be back.The purpose of the activity is in not getting lost,not in seeing how fast you can go,so always stick together,waiting for slower friends to catch up.
              •See if your school or a club organizes orienteering(越野识途比赛) activities,in which you need a map and a compass to find your way.This can be done as a sport,with teams trying to find the way from A to B (and B to C,etc.) in the fastest time,or simply as a sparetime activity.It enables you to be familiar with the use of maps and compasses and gain some practical skills.In some way,it's not only good fun,but also a great way to keep fit.
              No matter which way you choose,it's not only good fun,but a great way to keep fit.

              (1) Sitting beside the driver,you should ______ .
              A. direct the driver when necessary
              B. look ahead to see where there's a gas station
              C. move to the back seat if feeling uncomfortable
              D. keep looking at the map to find another place to go to
              (2) Why do you need to wait for the slower friends in the exploration? ______
              A. To show them how fast you can go.
              B. To avoid yourself or your friends getting lost.
              C. To share the fun with him/her in exploration.
              D. To tell him/her what's going on with the group members.
              (3) Orienteering activities can ______ .
              A. make people work fast
              B. help people stay healthy
              C. help people organize other activities
              D. make people get prepared for sports
              (4) The text mainly talks about ______ .
              A. the fun of exploration
              B. what to bring for exploration
              C. the way to use a map in exploration
              D. how to prevent people getting lost in exploration.
