You really have to get very old before you realize you’re old.I’m in my early thirties and I don’t feel sorry for my age yet.However,sometimes when I 16 on my childhood and compare something to today’s,I find some things have certainly changed.
One area of change is televisions.Some changes are good.Some changes,17 are not so good.
When I started school,18 people didn’t have a television.TV was just beginning to get 19 .My father decided to buy a 16-inch black and white Motorola set.I still 20 watching the Lone Ranger save people from the bad guys on that small electronic machine.That was 21 .
Now televisions have larger pictures in full colour.The pictures are clearer and the sound is much more realistic.The new high definition(高清晰) sets are made to be like 22 screens.
These are hundreds of channels and more shows than one person could ever watch.There are many fine entertainment and educational 23 .There’s also a lot of garbage that most parents don’t want their kids to watch.In a word,we have more 24 ,and that is good.
I 25 what television will be like when today’s kids are my age.
