18．The biggest secret about inventing is that anybody can do it!Perhaps this sounds crazy，but it's true．Maybe you have the wrong idea about inventing，so read on to discover the truth．
Wrong idea No.1：An invention has to be something completely new．
Well，inventing means creating something"new"，but the idea could come from something that already exists（存在）．The Wright brothers，for example，got the idea for building a"flying machine"from watching birds．
Wrong idea No.2：Inventors are born，not made．
There are a lot of factors（因素） that make invention possible．Take Mazart，for example．He was born with a talent for musical composition．But other factors were also important for his creativity．His father was a music teacher，and Mozart practiced for hours every day，from the time he was four years old．Thomas Edison said that being an inventor was"99% hard work and 1% inspiration"！
Very successful creators don't give up when they get something wrong．As one inventor said，"A failure is the right answer to the wrong question．"
Wrong idea No.3：Inventors are always old people．
Don't believe that you can't invent something when you are young．Here are two examples of young inventors：Louis Braille went blind when he was a child．When he was fifteen，he invented a system of reading and writing for blind people that is still used in most countries today．
As a young man，George Nissen was watching some artists performing in a show．He watched how they fell into the safety net and then jumped back up again．This gave him an idea，and he invented the trampoline（蹦床）．

48．D got the idea for building a"flying machine"from watching birds．
A．Mazart  
B．George Nissen
C．Louis Braille   
D．The Wright brothers
49．The underlined word"talent"probably meansC．
A．態(tài)度  
B．品質(zhì)  
C．天賦      
D．能量
50．Which of the following is the writer's opinion？A
A．Anybody can do inventing．
B．Inventors are born，not made．
C．Inventors are always old people．
D．An invention has to be something completely new．
51．The best title for the passage would beD．
A．How to Perform in a Show 
B．Be a Composer
C．How to Help Blind People 
D．Be an Inventor．

49．C  詞義猜測(cè)題．根據(jù)Take Mazart，for example．He was born with a talent for musical composition．例如，莫扎特，他的出生對(duì)于樂(lè)曲有天賦．可知莫扎特的音樂(lè)天賦，talent意為天賦．故選C．

6．One day，I heard an American boy said to a Chinese girl student，"You speak very good English．"But the girl answered，"No，no．My English is very poor．"The foreigner was quite surprised at the answer．Thinking he had not made himself understood or the girl had not heard him clearly，he said，"Yes，indeed，you speak very well．"But the girl still kept saying，"No．"In the end，the American boy could not understand and didn't know what to say．
What's wrong with the girl's answer？She didn't accept a compliment（夸獎(jiǎng)） in the same way as the American people do．She should answer，"Thank you"instead of"No"．She really understood what the American boy had said，but she thought she should be modest．In the west，people will feel proud and confident when they are praised．So if someone says the dishes you have cooked are very delicious，you should say，"Thank you．"
In our country，we think being modest is a virtue（美德）and being proud is a bad thing，but in my opinion，being confident does not mean being proud，so sometimes you should be confident instead of being modest．
If you are modest and say，"No，I'm afraid I can't do it well"，while working in a western country，the others may think that you really cannot do it．If you often say，"No"，you will certainly be looked down upon by others．When asking for a job，if one says something like‘'Yes，I can certainly do it"instead of"let me have a try"，he or she will expect to get it．So in the west，you should be brave to show your self-confidence．

46．Why did the Chinese girl say"No"when she was praised？C
A．Because she thought she should be proud．
B．Because she thought she should be confident．
C．Because she thought she should be modest．
D．Because she thought she is a student．
47．If you say，"I can do it well．"when asking for a job in the west，the others may think thatA．
A．You can do it well．
B．You can't do it well．
C．You like doing it．
D．You don't like doing it．
48．What does the underlined part"looked down upon"mean in Chinese？A
A．瞧不起   
B．瞧得起   
C．表?yè)P(yáng)   
D．批評(píng)
49．Which of the following is true according to the passage？C
A．The girl didn't hear the boy clearly．
B．The American boy understood the girl's answer．
C．In China，people think being modest is a virtue．
D．The writer thinks being modest means being proud．
50．What does the writer want to tell us？D
A．We should be proud and selfish in the west．
B．We should be modest and confident in the West．
C．We should be modest and brave in the West．
D．We should be brave and confident in the West．
