8．Do you have imagination？Do you like to solve problems？Can you think out of the box？If so，you could be the next great inventor．"But I'm just a kid，"you might say!Don't worry about a little thing like age．Some of the greatest inventors in the world get their start as kids．
For example，Benjamin Franklin created paddles （桨） for his hands to help him swim faster when he was only 12 years old．His creation led to today's flippers （橡胶蹼）!
You don't have to be an adult，a scientist or a genius （天才） to be an inventor．One thing you need is：curiosity and imagination．Kids are known for looking at things in new and uniqueways．Sometimes their understanding of things leads to great inventions!
Sometimes inventors come up with completely new things that solve a problem．At other times new inventions are only things that are changed or improved．Then they work better or serve a different purpose．
So what should you do if you have a great idea for an invention？Talk to a friend of family member about it．Ask them to help you create a working model of your idea．
Once you have a working model，you should test it．Sometimes after the test，you may find your idea is not as great as you thought．At other times you realize it is a good idea and your working model can help you work out how to make it better．
If you need some ideas，consider these kids and their inventions：
Frank Epperson invented Popsicles （冰棍） when he was 11．One night he mixed soda powder （苏打粉） and water with a stick．He left it outside all night．The next morning，he found that the stick had frozen （冻结） inside the drink during the cold night．
Chester Greenwood created earmuffs （耳罩） when he was 15．He found his ears got painfully cold when he was skating．He decided to solve the problem．He found a piece of wire （电线），and his grandma helped him pad （用软物填塞） the ends．
At the age of 15，Louis Braille invented the system that allowed blind people to read．
52．The underlined word"unique"in Paragraph 3 probably means"C"．
A．strict
B．famous
C．unusual
D．popular?

A．Benjamin Franklin made paddles for his feet

54．The writer probably agrees thatD．

15．

London has a new magazine．But it is not printed on paper．Everyone who has a television can receive it because it is on TV
In order to read this magazine，you have to have a decoder（解码器）．Each page of it is numberes，so you only have to dial（拨号）the number to choose which subject you want to read about．There are all kinds of information一everything is included from cooking to the latest sports news．
If you want to read the news，the first thing you have to do is to turn to the back page，which has an easy-to-remember page number，100，for example．Then you start choosing what you want to read．The news is on page 101to 109，so you put in the numbers and the news appears written across your screen．Perhaps you want to go out in the afternoon，so you press 181，and a brightly colored weather map appears on the screen．But the weather is terrible，so you decide to go shopping and dial 162for a list of the week's best bargains（廉价商品）．But should you drive or take the train？To answer that question，you only have to press 189for the traffic report．It is very simple to use．But probably the best thing about the service is that it is being updated（更新）all the time．Journalists type new material directly onto the screen and all the pages of the magazine can be replaced in minutes．
London already has three services．One，sent out by TV，is called ORACLE while the other two，on BBC，are called CEEFAX because they let you see facts．Although CEEFAX and ORACLE have been operating for some time，they have not been well publicized（宣传）．BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere．But many people would agree that is a breakthrough（突破）as great as the invention of printing，which could not just change our reading habits but our whole way of life．
