Model Test 10

　　For many people the most exciting development in recent years is Picturephone service. Picturephone service, 1 became available commercially in the 1970�餾, was 2 used by large business corporations. But as Picturephone service becomes available, it will no doubt 3 from the office to the home. It is already clear that "the next 4 thing to being there" is going to be a Picturephone call.

　　Possibly the most significant research now 5 is in the us e of the laser beam in telephone communications. This "new 6 , first produced by scientists in 1960, can beam continuously and 7 extraordinary intensity. 8 using light to 9 , they are thinking of ways to use lights to communicate by. 10 , they are thinking of using light for the same purpose 11 radio waves are now used to 12 telephone calls, television programs; and data messages from one point to another. With the 13 of Picturephone service and high speed data communications 14 computers, present message�瞔arrying 15 may soon become inadequate. If it turns out to be technically and economically sound, the laser might prove to be a major 16 in telephone communications.

　　Current research in telephone communications is so extensive and changes are coming about 17 no one can predict with accuracy 18 the telephone of tomorrow will be like. But there is at least on e prediction that can be made 19 : there would be more and more telephones in the future, and they will be 20 .
