I remember doing the household chores to help my mother when I was nine．I hated changing the vacuum cleaner（真空吸塵器）bag and picking up things the machine did not suck up．Twenty years later，in 1978，with this lifelong dislike of the way the machine worked，I decided to make a bagless one．
Easier said than done，of course．I didn't realize that I would spend the next five years perfecting my design，a process that resulted in 5，127 different prototypes（樣機(jī)）．By the time I made my 15th prototype，my third child was born．By 2，627，my wife and I were really counting our pennies．By 3，727，my wife was giving art lessons for some extra cash，and we were getting further and further into debt．These were tough times，but each failure brought me closer to solving the problem．
In the early 1980s，I started trying to get licensing agreements for my technology．The reality was very different，however．The major vacuum makers had built a business model based on the profits from bags and filters（濾網(wǎng)）．No one would license my idea，not because it was a bad one，but because it was bad for business．But soon after，the companies that I had talked with started making machines like mine．I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner．
I was still in financial difficulties until 1993，when my bank manager personally persuaded Lloyds Bank to lend me ＄l million．Then I was able to go into production．Within two years，the Dyson vacuum cleaner became a best-seller in Britain．
Today，I still embrace risk and the potential for failure as part of the process．Nothing beats the excitement of invention．
（1）What drove the author to make a bagless vacuum cleaner？DD
A．His willingness to help mom．
B．His curiosity about machines．
C．His trouble in doing family chores．
D．His discontent with existing cleaners．
（2）What does paragraph 2 mainly tell us？CC
A．The help from the author's wife．
B．The financial problems of the family．
C．The tough process of the new invention．
D．The procedures of making a bagless cleaner．
（3）Why did the companies refuse to license the author's technology？AA
A．They thought they might suffer loss．
B．They considered it not good enough．
C．They faced legal problems themselves．
D．They had begun making such machines．
（4）What lesson may the author learn from the experience？BB
A．Think twice before acting．
B．Failure is the mother of success．
C．Actions speak louder than words．
D．A good beginning makes a good ending．

1．For several days Ⅰ（Jane Eyre） saw little of Mr.Rochester.One evening，I was invited to talk to him after dinner.There was a smile on his lips，and his eyes were shining brightly.As I was looking at him，he suddenly turned around and asked me， "Do you think I'm handsome，Miss Eyre？"
The answer somehow slipped from my tongue before I realized it： "No，sir."
"Ah，you are really unusual!You look like a quiet，serious little person，but you can be almost rude."
"Sir，I'm sorry.I shouldn't have given an immediate answer to such a question about appearances；I should have said that beauty doesn't matter，or something like that."
"No，you shouldn't!I see，you criticize my appearance，and then you stick a sly penknife under my ear!You have honesty and feeling.There are not many girls like you.Perhaps you have awful faults to counterbalance（抵消） your few good points."
I thought to myself that he might have too.He seemed to read my mind，and said quickly， "Yes，you're right.I have plenty of faults.I went the wrong way when I was twenty-one，and have never found the right path again.I might have been as good as you，and perhaps wiser.I am not a bad man，take my word for it，but I have done wrong.It wasn't my character，but circumstances that were to blame.Why do I tell you all this？Because you're the sort of person people tell their problems and secrets to，because you're sympathetic and you give them hope."
"Don't be afraid of me，Miss Eyre，" he continued." You don't relax or laugh very much，perhaps because of the effect Lowood has had on you.But in time you will be more natural when you're with me，and laugh，and speak freely.You're like a bird in a cage.When you get out of the cage，you'll fly very high.Good night."
（1）Why did Mr.Rochester say "and then you stick a sly penknife under my ear" in paragraph 5？
A．Because Jane had offered some unnecessary explanations.
B．Because Jane had intended to be more critical.
C．Because Jane had regretted having talked to him.
D．Because Jane had intended to kill him with a knife.
（2）From what Mr.Rochester told Miss Eyre，we can conclude that he wanted to.
A．tell her all his troubles
B．tell her his life experience
C．change her opinion of him
D．change his circumstances
（3）Mr.Rochester soundedat the end of the passage.
A．rude
B．cold

2．To me，life without music would not be exciting．I realize that this is not true for everybody．Many people get along quite well without going to the concert，and listening to the record．But music plays an important part in everyone's life，whether he realizes it or not．Try to imagine，for example，what films or TV plays would be like without music．Would the feelings，the moving plot，and the greatest interests，be so exciting or dramatic？I'm not sure about it．
Now，we have been speaking of music in its more common meaning----the kind of music we hear in the concert hall．But if we look at some parts of music more closely，we discover them in our everyday life too----in the rhythm of the sea，the melody of a bird in the woods and so on．So music surely has meaning for everyone，in some way or other．And，of course，it has special meaning for those who have spent all their lives working on playing or writing music．
It is well said， "Through music a child enters into a world of beauty，expresses himself from his heart，feels the joy of doing things alone，learns to take care of others，develops his mind and makes his body strong．"
（1）What does the writer say more about in the text？
A．Life full of music．
B．The importance of music．
C．Life without music．
D．The development of music．
（2）From the text，we learn that many people．
A．go to the concert instead of enjoying music
B．get along quite well without music
C．don't realize the importance of music
D．think music would be less exciting than films
（3）What does the underlined word "melody" mean in the text？
A．flying
B．living
C．looking
D．singing
（4）From the last paragraph，we learn that music．
A．is very necessary for our everyday life
B．is very important，especially for children
C．can make our life exciting and dramatic
D．can enter another beautiful world發(fā)布：2025/1/1 18:0:1組卷：6引用：3難度：0.6 -
