1.Air pollution is getting more and more serious in many places around the world.The fact that public parks in cities become crowded proves that people long to breathe in green,open spaces.And,in these surroundings,they are generally both peaceful and peaceable.It is rare to see people being at odds or even fighting in a garden.It seems to be proved that if human beings can freely breathe and share air,there is no primary reason for them to struggle with one another.
       But do we only sense what life could be when we enjoy green spaces?
       The plant world silently shows us what a reflection of life truthfully is.It also helps us to a new beginning,urging us to care for our breath.We must,in turn,care for it,opposing any sort of pollution that destroys both our world and that of plants.The interdependence to which we must pay the closest attention is what exists between ourselves and the plant world.Often described as"the lungs of the planet",the woods that cover the earth offer us the gift of breathable air by releasing oxygen.But their capacity to renew the air polluted by industry has long reached its limit.If we continue to pollute the air by filling it with chemicals and destroy the ability of plants to restore it we will soon pull our world into an unavoidable disaster.
      Humans must learn to share life,both with each other and with plants.This task can be carried out only when each takes it upon her 一 or himself 一 and only when all work together.The lesson taught by plants is that human life can only exist with nature.We must come to view the air,the plants and ourselves as the contributors to the protection of life and growth,rather than productive objects we can use and throw away freely.Perhaps then we would finally begin to live,rather than merely survive.

13.I'm seventeen.I had worked as a box boy at a supermarket in Los Angeles.People came to the counter and you put things in their bags for them and carried things to their cars.It was hard work.
While working,you wear a plate with your name on it.I once met someone I knew years ago.I remembered his name and said,"Mr.Castle,how are you?"We talked about this and that.As he left,he said,"It was nice talking to you,Brett."I felt great,he remembered me.Then I looked down at my name plate.Oh,no.He didn't remember me at all.He just read the name plate.I wish I had put"Irving"down on my name plate.If he'd have said,"Oh yes,Irving,how could I forget you?"I'd have been ready for him.There's nothing personal here.
The manager and everyone else who were a step above the box boys often shouted orders.One of these was:you couldn't accept tips.Okay,I'm outside and I put the bags in the car.For a lot of people,the natural reaction is to take a quarter and give it to me.I'd say,"I'm sorry,I can't."They'd get angry.When you give someone a tip,you're sort of being polite.You take a quarter and you put it in their hand and you expect them to say,"Oh,thanks a lot."When you say,"I'm sorry,I can't."they feel a little put down.They say,"No one will know."And they put it in your pocket.You say,"I really can't."
It gets to a point where you almost have to hurt a person physically to prevent him from tipping you.It was not in agreement with the store's belief in being friendly.Accepting tips was a friendly thing and made the customer feel good.I just couldn't understand the strangeness of some people's ideas.One lady actually put it in my pocket,got in the car,and drove away.I would have had to throw the quarter at her or eaten it or something.
I had decided that one year was enough.Some people needed the job to stay alive and fed.I guess I had the means and could afford to hate it and give it up.

24.What can be the best title for this text?B
A.The Art of Taking Tips
B.Why I Gave up My Job                  
C.How Hard Life Is for Box Boys
D.Getting along with Customers

B.Mr.Castle mistook Irving for Brett
C.with a name plate,people can easily start talking
D.Irving was the writer's real name
26.The box boy refused to accept tips becauseC.
A.customers only gave small tips
B.he didn't want to fight with the customers
C.the store didn't allow the box boys to take tips
D.some customers had strange ideas about tipping
27.The underlined phrase"put down"in the third paragraph probably meansD.
A.misunderstood        
B.defeated        
C.hateful

17.Henrietta Lacks was born in 1920 in Virginia and raised on a tobacco farm.She married her first cousin,David Day and later settled near Baltimore in Turner Station where Day worked at a steel mill.After giving birth to her fifth child,she was diagnosed with cervical cancer.She was treated at Johns Hopkins,the only hospital within twenty miles that treated black patients and had been established as a charity hospital.
    In an attempt to grow everlasting cells,Dr.George Gey took samples of all women who came to Hopkins with cervical cancer.After taking a biopsy (活检) of Henrietta's cervical cancer,researcher Dr.George Gey discovered that unlike any cells they had seen before,Henrietta's cells could not only reproduce,but thrive outside the body--a breakthrough that would change modern medicine.Actually,her cells doubled in size every 24 hours and Dr.Gey shared these cells for free with any researcher interested.Later,Dr.Stanley Gartler found that Henrietta's cells were even capable of jumping out of the petri dish(培养皿) and taking other cell types.As a result,these cells,named HeLa(for Henrietta Lacks) were essential in the research into cancer,AIDS,the effects of radiation and poisonous substances,gene mapping,and countless other scientific pursuits.And they've been used in tens of thousands of research studies.
    Ms.Lacks died not too long after her diagnosis in 1951.She unknowingly held the key to unlocking medical advancements in her tumor cells.Now,decades after Henrietta's death,her cells are still alive.For many years,her family knew nothing about the impact her cells had on medical science-she provided a crucial sample of cells that has furthered the knowledge of medical science and disease prevention.
    Now nearly 60years after her death,in May 2011,Morgan State University in Baltimore awarded her an honorary degree.

25.What is the passage mainly about?A
A.A woman's contribution to medical progress.
B.The contribution of Johns Hopkins.
C.The original research of cancer.
D.The death of a black patient.
26.Which word can describe the cells of Henrietta Lacks?C
A.Radioactive.B.Poisonous.C.Active.D.Interesting.
27.What does the underlined word"thrive"mean probably?B
A.Die.B.Grow.C.Break.D.Change.
