1．Television has turned 88 years old on September 7，2015，and it has never looked better．In its youth，television was a piece of furniture with a tiny，round screen showing unclear pictures of low budget programs．In spite of its shortcomings，it became well-received．Between 1950 and 1963，the number of American families with a television jumped from 9% to 92% of the population．
As the audience got larger，the technology got better．Television sets became more reliable through the 1960s．Both of the reception and the picture improved．The major networks started broadcasting programs in color．
Even greater improvements were coming according to Sanford Brown，who wrote an article for the Post in 1967．Surprisingly，just about every prediction he made in the article became a reality．For example：All sets in the not distant future will be color instruments．He also predicted that TV sets would become smaller，simpler，more reliable and less expensive and may forever put the TV repairman out of work．Smaller sets do not，of course，mean smaller screens．TV engineers expect screens to get much bigger．However，today's 3D TV is even farther away，if it's coming at all．There is some doubt whether the public would be eager to pay for it，in view of people's cold reception given to 3D movies．
But the technology with the greatest potential，according to Brown，was cable television （有線電視），which was still in its early stages then．As he predicted，the future of cable television was highly interactive．It wasn't cable television that gave Americans their electronic connection to the world，however．It was the Internet．He even foresaw the future office：using picture phones，big screen televisions for conferences，and computers providing information，at the touch of a button．
Brown ever said，"The future of television is no longer a question of what we can invent．It's a question of what we want．"

解答 29--31 ABC
29．推理判斷題．根據(jù)第一段In its youth，television was a piece of furniture with a tiny，round screen showing unclear pictures of low budget programs．In spite of its shortcomings，it became well-received．可知，在它的早期，電視是一種微小的家具，顯示不清的圓形屏幕．盡管這些缺點，它還是很受歡迎．故選A．
30．B 推理判斷題．根據(jù)倒數(shù)第二段However，today's 3D TV is even farther away，if it's coming at all．說明他沒有預測到3D技術(shù)在電視上的運用．故選B．
31．C 主旨大意題．根據(jù)文章第一段內(nèi)容就可以知道文章主要講述的就是電視的發(fā)展歷史．故選C．
