1.Eyesight plays a very important role in our daily life.Every waking moment,the eyes are working to see the world around us.Over forty percent of Americans worry about losing eyesight,but it's easy to include steps into our daily life to ensure healthy eyes.Here are five suggestions for a lifetime of healthy eyesight:
•Schedule yearly exams.(31)B Experts advise parents to bring babies 6to 12months of age to the doctor for a careful check.The good news is that millions of children now can have yearly eye exams and following treatment,including eyeglasses.
•Protect against UV rays (紫外線).Long-term stay in the sun creates risk to your eyes.No matter what the season is,it's extremely important to wear sunglasses.(32)C
•Give your eyes a break.Two-thirds of Americans spend up to seven hours a day using computers or other digital products.(33)G Experts recommend that people practice the 20/20/20rule:every 20minutes,take a 20-second break and look at something 20feet away.
•(34)A As part of a healthy diet,eat more fruits and vegetables each day.Vitamins(維生素) C and E help protect eyesight and promote eye health.
•Practice safe wear and care of contact lenses(隱形眼鏡).Many Americans use contact lenses to improve their eyesight.While some follow the medical guidance for wearing contact lenses,many are breaking the rules and putting their eyesight at risk.(35)F Otherwise,you may have problems such as red eyes,pain in the eyes,or a more serious condition.

A.Eat your greens.
B.Eye care should begin early in life.
C.They can properly protect your eyes.
D.Stay in good shape by taking more vitamins.
E.Parents usually don't care about their own eyesight.
F.Always follow the doctor's advice for appropriate wear.
G.This frequent eye activity increases the risk for eye tiredness.

The brothers stood at each end of the bridge,and then they met in the middle,taking each other's hand.They turned to see the carpenter lift his toolbox on his shoulder."No,wait!Stay a few days.I've a lot of other projects for you,"said the older brother."I'd love to stay on,"the carpenter said,"but,I have so many more bridges to build."

1.A current topic of debate is the amount of support and services we are willing to provide for disabled people.Many people believe that society has become more caring over the old.However,if we look back in time,this may not prove to be true.A good example can be found by looking at some remains(遺。 of a prehistoric culture.
Several skeletons(骨架) were found in the Shanidar Cave in Iraq.It was the home of a tribe (部落) of Neanderthals who existed more than 40 000 years ago.One of these skeletons was a man about 40years old,an old age for that period.He is thought to have been killed by a falling stone.Careful study of the bones has shown that the man's right arm had never fully developed and had been cut off below the elbow(肘).The condition of the teeth was also unlike that of other Neanderthal men's.They showed signs of excessive(過(guò)多)use,as if they had been used to make up for the lack of a right arm.
How could someone so disabled from his earliest years have survived to become an adult,and even live on to old age?Societies in such early times faced severe conditions.People who could hunt for meat were few.A disabled person must have needed to keep close to the cave and been provided with meat.In fact,more care were shown towards this disabled man during that time,which suggests that the ancient people did better in caring their disabled people than we do in present-day societies.Such concern indicates a sense of unity(團(tuán)結(jié)) and cooperation that made possible the future achievements of humanity.With this in mind,are we doing enough for the disabled?Rather than being too proud of the efforts that modern society has made,it would be wise to consider if we even equal the efforts of the old societies.

32.Considering the remains of this prehistoric culture makes usC.
A.believe that society has become more caring over time
B.look back at Iraq history with admiration
C.question if society has become more concerned about the disabled
D.want to give more support to primitive societies
33.The man could live until such an old age becauseC.
A.he could use his teeth very well
B.he didn't have to do any hunting
C.he was taken good care of
D.the environment was excellent
34.The example of this ancient tribe suggests thatD.
A.everyone could take part in most of the hunting activities
B.it was easy to find enough meat to feed everybody
C.life was not as difficult as modern man may think
D.they had greater care for human life than people commonly think
35.The author believes that true civilization is achievedC.
A.by looking to the future achievements of humanity
B.by modern people taking pride in their accomplishments
C.by supporting and taking care of all its members
D.only when we show proper concern for people living in the ancient time.

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(dòng)機(jī))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.

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(chǎn) 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(píng)) 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        
B.The Best Advice I've Ever Had
C.My Father                            
D.My Childhood.
