23. Each member country of WTO must ____

     When I was a college student, I did a lot of traveling abroad. That was because a professor   1   me to
do so. She said, "Now is the time for you to travel around the world,   2   your knowledge through actual
experiences and have fun!" I   3   her.
     Since I started to work for a   4   company, however, I have done most of my traveling through the
Internet. By using the Internet, I have seen the   5   of many cities on my computer screen. And I have
really made business   6  , too. With the help of the Internet, I have also got   7   about food in different
countries.
     Therefore, I was beginning to feel that actual trips were   8   necessary when I happened to read a
famous chef's (厨师) comment on the Internet. He said, "It is very difficult to have real Italian food in a
foreign country, because we enjoy food and the   9   around us at the same time. So why don't you fly over
to Italy and enjoy real Italian  10 ?" Those words reminded me of my  11   advice. As information technology 
  12   , you might be able to do without making some real trips. But this also means that you will miss the
various  13  you can get from traveling.
     Today there are people who  14  direct communication with others and spend much of their time on the
Internet. It is not surprising to see a group of people  15   not with each other but into their micro phones.
It seems as if such people are  16   by an invisible wall. They seem to be losing out on a good chance to 
 17  and talk with other people. I do not think that they are taking good advantage of information technology.
We should use information technology as a tool to make our daily  18  more fruitful. However, we should
never let it   19   our time for face-to-face communication. Let's make use of information technology more
  20 , and have great fun in experiencing the actual world.
