Is the art of conversation dying? The other day, my wife   1  two teenage children did something we haven’t    2  for ages. It didn’t require the Internet, a TV screen, batteries… or anything else for that matter. But we all   3  it so much we’re thinking of doing it again sometime.
We had a conversation. The kind of real, live conversation that was   4  when I was growing up, but which seems all too rare these days. Today we have chat rooms, text messages, e-mails but we seem to be losing the   5  of communicating face-to-face. We all know  6  young people are out on a date(约会）these days, they spend most of that time   7  their mobile phones. And teenagers nowadays seem to   8  communicating with their friends by sending text messages rather than actually   9  to them.
If we carry on like this，in the future, we’ll lose the use of our   10 . What do you think? E-mail me, and who knows? Maybe we could even have a real conversation about it!

Is your schoolbag too heavy? The e-schoolbag will help you. It is said that e-schoolbags are going to be brought into   43  in Chinese middle schools soon.
Heavy schoolbags have been a serious   44  for a long time. But the e-schoolbag will  45 . An e-schoolbag is  46  lighter than a usual schoolbag. Perhaps, the e-schoolbag should be   47  an e-textbook. It is a small computer for students. It is as   48  as a usual book,   49  it can still have all the things for study, such as textbooks, exercise books and so on which can be made   50  chips(芯片) like stamps. The students can read the text page by page on the screen, take notes, or even send e-mails to their teachers. They only need to   51  the right chip into the e-schoolbag. Then they can use it.
Some people say   52  e-textbooks can be easily broken, while others say it is not good for eyes. But only time will tell.

Is it difficult for you to get up in the morning? Do you sometimes oversleep? Do you often     26    late? Yes? Then Hiroyuki Sugiyama of Japan invented a     27     bed for you. His bed will wake you up! Here is    28    it works.
There is an alarm clock and a recorder（录音机） in the bed. When the clock      29   a sound, you’ll have a few minutes to wake up. Then the recorder plays light music with a little girls’    30     voice. She says quietly, “Wake up, my dear.” A few     31     later, a second recording plays. It can be unpleasant sounds, “Wake up,    32    you’ll be late!”
If you don’t get up after the     33    recording, you’ll be sorry. There is a mechanical (机械的) “    34    ” in the bed. It can kick（踢） you in the head. Then the bed ­    35    for a few more minutes. What? You’re     36     lying in bed! Slowly the top of the bed goes     37    . The end of the bed goes lower and lower.     38     the bed is straight. You slide off(滑下)the bed and fall onto the    39     . You are     40    the bed and awake.
