9．The world moves so quickly nowadays．With so many daily responsibilities，some of us can hardly keep our heads above water．Should we make time for studying  or appreciating the arts？Many people would say the arts are nice，but not necessary．In school，students should focus on languages，math and science．Painting，drama and music are frills． After graduation，listening to Mozart won't lead you to a better-paying job．
     In truth，spending time learning to appreciate the arts may be more worthwhile than you think．A recent British study examined the salaries and jobs of people who spent time enjoying the arts when growing up．The researchers found those who enjoyed the arts from an early age had better jobs and higher salaries than those who didn't．What's the link？How could visiting a museum，enjoying a symphony，or honing painting skills lead to career success？It turns out that the arts help us develop many useful skills．
      Other students have found students studying the arts exercise their reasoning ability．The skill helps with problem-solving．Creative and critical-thinking abilities are also developed through art study．Moreover，those who enjoy the arts have more motivation（動機）to achieve．Students who practice an art experience the rewards that come from persistence and goal-setting．These benefits also extend to those who make time to appreciate the arts beyond their school years．The best kind of art stirs our imagination and makes us think．Paintings aren't just pretty pictures．They tell stories about the lives of the subjects or about the experience of the painter．See Michelangelo's art and you'll taste the power of his faith in God．Look at the world from Picasso's point of view，and you see everyday life in new ways．Those who appreciate the arts also gain a broader perspective on the world．The arts reveal and explain the world beyond our own personal knowledge which can help us better communicate and cooperate with other people．
      If you want to better yourself，go and enjoy the arts．Check out an art gallery or a museum．Take in a play．You won't regret it and it will do you more good than you can imagine．
32．The underlined word"frills"in paragraph 1 probably meansA．
A．decorations    B．necessities   C．fillings      D．possessions
33．The benefits of enjoying arts are all of the following EXCEPTB．
A．communicating skills              
B．high positions
C．problem-solving  abilities            
D．creation and imagination
34．How is the passage developed？A
A．By providing examples             
B．By analyzing causes
C．By listing the facts                 
D．By comparing the facts
35．What is the author's attitude towards art appreciation？D
A．Doubtful      B．Opposed   C．Critical        D．Supportive．

6．We have a strange and strong belief in the idea of perfection．Driven by our culture，we struggle for an unattainable ideal：If I have the perfect parents，perfect grades，perfect…，then I would be happy．We seek what we can't have without remembering that we don't actually need to be perfect．Imperfection allows us to be human．
Parents，teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive．However，what job or school requires you to develop a cure for some form of cancer by the age of 18？Although these grades would be admirable achievements，are they worth losing sleep over？We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job．Making use of our thirst for perfection，the whole college and career industries have emerged claiming to help us reach our goals．
Truth is，you only need to be good enough to get into the conversation．It is what you do afterwards that sets you apart．Focus more on your passions．Don't worry about anything secondary to your passions．You don't become an expert at anything if you spent your time trying to succeed in everything you do．You only become an expert when you devote your time to that one project that truly brings you joy．
As members of this society，we have a responsibility to be excellent in what we do，not perfect．Although perfection can be a goal，it should not be the only goal．We only have 24 hours in a day and seven days in a week．Thus，we need to plan what we want to do and cut out the activities we cannot do．
With everything，though，make sure you're doing enough．Pursuing your passions is not enough of a reason to completely give up on everything else．Try as hard as you can and let your future worry about itself．Worry about your task at hand and you will be successful in achieving your dreams．Most of all，remember that you're going to be okay．
8．It is implied in Paragraph 1 that there is a culture whereB．
A．Students are driven to learn concepts
B．great importance is attached to perfection
C．imperfect people aren't happy at all
D．perfect grades result from remembering facts
9．We can infer from the second paragraph thatD．
A．a perfect grade is worth losing sleep over
B．the whole college and career industries are perfect
C．some schools ask students to invent some medicine
D．someone is profiting from our search for perfection
10．According to the author，we shouldB．
A．see becoming perfect as our responsibility
B．deal with what we hope to do first
C．set a goal of perfection in our life
D．worry about our future dreams
11．What might be the most suitable title for the passage？B
A．How to be perfect
B．Being enough is enough
C．Finding your own passions
D．Giving up your secondary goals．

13．When I was about 12，I had an enemy，a girl who liked to point out my shortcomings．Week by week her list grew：I was very thin，I was not a good student，I talked too much，I was too proud，and so on．I tried to bear all this as long as I could．At last，I became very angry．I ran to my father with tears in my eyes．
He listened to me quietly，and then he asked．"Are the things she says true or not？Janet，didn't you ever wonder what you're really like？Well，you now have that girl's opinion．Go and make a list of everything she said and mark the points that are true．Pay no attention to the other things she said．"
I did as he told me．To my great surprise，I discovered that about half the things were true．Some of them I couldn't change （like being very thin），but a good number I could-and suddenly I wanted to change．For the first time I went to a fairly clear picture of myself．
I brought the list back to Daddy．He refused to take it．"That's just for you，"he said．"You know better than anyone else the truth about yourself．But you have to learn to listen，not just close your ears in anger and feeling hurt．When something said about you is true，you'll find it will be of help to you．Our world is full of people who think they know your duty．Don't shut your ears．Listen to them all，but hear the truth and do what you know is the right thing to do．"
Daddy's advice has returned to me at many important moments．In my life，I've never had a better piece of advice．
21．What does"Week by week her list grew"mean？B
A．She made a list of my shortcomings and kept on adding new ones so it was growing longer and longer．
B．Week by week she discovered more shortcomings of mine and pointed them out to me．
C．I was having more and more shortcomings as time went on．
D．Week by week，my shortcomings grew more serious．
22．What did the father do after he had heard his daughter's complaint（抱怨）？C
A．He told her not to pay any attention to what her"enemy"had said and just do what she wanted to do．
B．He criticized （批評） her and told her to overcome her shortcomings．
C．He told her to write down all her"enemy"had said and pay attention only to the things that were true．
D．He refused to take the list and want to have a look at it．
23．Which do you think would be the best title for this passage？B
A．Not an Enemy，but the Best Friend

3．Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy．
"Our most important finding was the difference between Canadians and the others，"said Professor Michel Claes，the lead author of the study．"Canadians focus on independence and negotiation．On the other hand，Italians，for example，exercise more control．We found Canadians seem to focus on negotiation in case of a conflict．"
Claes said Canada，France and Italy were selected for the study because they share important cultural and social factors．"We chose FrenchCanadians because they share the same language as France，and originally came from France and share certain values．Italy was included because it was considered to have similar，strong and important family values，"he explained．
The researchers examined the emotional ties between parents and their children by questioning 1，256students aged 11to 19years old．
Canadian students reported less control and more free actions，according to the study．Italian parents were stricter and French parents were somewhere in the middle．
Claes explains that the differences lie in education in Canada，France and Italy．
"North America has its own educational values，which promote individualization．Tolerance and comprehension are encouraged．Italy，on the other hand，promotes respect of authority，control，and the need for permission．"he said．
Children from all three countries described their mothers as warm and communicative．Italian and Canadian children had similar feelings about their fathers，and reported high levels of emotional ties．But French fathers were generally thought by their children to be more distant and cold．
"We were surprised by this，"Claes admitted．"It seems as though the relationships between French mothers and their children were becoming closer over time，while fathers maintain a form of distance and coldness，which is more of a source of conflict in France than in the other countries．"
21．Professor Michel Claes believes that Canada，France and ItalyB．
A．have the same family spirit
B．have some similar cultural traditions
C．have experienced some similar social changes
D．have experienced similar cultural developments
22．How did the researchers carry out the study？B
A．By collecting answers of parents from Canada，France and Italy．
B．By collecting answers of children from Canada，France and Italy．
C．By questioning parents and their children from Italian Canadian families．
D．By  questioning  children  from  FrenchCanadian families．
23．According to Michel Claes，what mainly leads to the differences in parentchildren
relationships among Canada，France and Italy？C
A．Educational opportunities．
B．Traditional ideas．
C．Educational values．
D．Historical events．

8．As the population of the planet increases，so does the number of homes，business，parking lots，schools，airports and roadways．All these structures use electricity and need to be lighted．Humans demand light．They want their homes more comfortable and they want their streets safe．The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well．
Less than 10years ago I drove to a thinly populated section of my own，lay down in the middle of the road and watched an attractive meteor shower（流星雨）．If I did that today，I wouldn't be able to see the meteor shower．
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution．One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted．One only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky：a total waste of electricity．
Additionally，the production of electricity creates pollution by releasing greenhouse gases．This affects the air we breathe and our quality of life．
Scientists are also studying the effects of light pollution on wildlife．Thousands of birds die each year when they crash into highly lighted buildings，as they become puzzled by the light．It has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea．
Fortunately，light pollution is one of the easiest sources of pollution that can be corrected without a negative effect．Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution．

33．According to the passage，the best way to deal with light pollution is toC．
A．Reducing the output of lights
B．Educating people about light pollution
C．Avoiding the use of unnecessary lighting
D．Inventing environmentally-friendly lights
34．What can be inferred from the passage？D
A．Astronauts can't see clearly in space nowadays
B．Global warming results in light pollution in some way
C．We are almost at a loss how to deal with light pollution
D．Some animals use natural light to direct their movements．
35．What will probably be provided following the last paragraph？D
A．Benefits of searching on Google 
B．More bad effects of light pollution
C．Helpful tips for suffering the Internet 
D．Ways to decrease light pollution．
