A few years ago, I took a sightseeing trip to Washington,D.C.Standing outside the Ronald Reagan Center,I heard a voice say, “Can you help me?” When I turned around, I saw an elderly blind woman with her hand extended.In a natural reflex (反应),I reached into my pocket, pulled out all of my loose change and placed it on her hand without even looking at her.I was annoyed at being bothered by a beggar.But the blind woman smiled and said, “I don’t want your money.I just need help finding the post office.”

     In an instant,I realized what I had done.I judged another person simply for what I assumed she had to be.I hated what I saw in myself.This incident re-awakened my belief in humility(谦恭),even though I’d lost it for a moment.

     The thing I had forgotten about myself is that I am an immigrant.I left Honduras and arrived in the U.S.at the age of 15.I started my new life with two suitcases,my brother and sister,and a strong,serious-minded mother.Through the years,I have been a dishwasher, mechanic and pizza delivery driver among many other humble jobs,and eventually I became a network engineer.

     In my own life,I have experienced many open acts of prejudice(偏见).I remember a time, at age 17 ----- I worked as a waiter, and I heard a father tell his little boy that if he did not do well in school,he would end up like me.I have also witnessed the same treatment of my family and friends,so I know what it’s like,and I should have known better.

     But now,living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been,and to lose sight of where I want to be going.That blind woman on the streets of Washington,D.C.,cured me of my blindness.She reminded me of my belief in humility and to always keep my eyes and heart open.By the way,I helped that lady to the post office.And in writing this essay,I hope to thank her for the priceless lesson.

阅读下面短文,从题中所给的四个选项(A、B、C和D)中,选出最佳选项。

  Cut out part of a healthy person's liver and transplant it into a sick person-it sounds like a complicated and dangerous operation, not to mention very expensive.But it is sometimes the only possible cure for a seriously ill patient with liver disease.

  Until now British scientists have just announced a new stem cell technique, which allows them to grow healthy liver cells outside human bodies.According to the researchers, it could be another five to 10 years before the technique can actually be used to help patients with liver disease.However, they say the method might one day replace liver transplants altogether.The study was led by the University of Cambridge and the Welcome Trust Sanger Institute, a British genomics and genetics research institute.It was published in the journal nature on October 12, 2011.

  The researchers took skin cells from a patient with a mutation(变异)in a gene called alphal-antitrypsin(a-l抗胰蛋白酶).This gene makes a protein that protects our bodies against inflammation(炎症).People with changed or damaged alphal-antitrypsin are not able to release the protein correctly from the liver, so the protein is trapped there and eventually leads to liver cirrhosis(肝硬化).

  Scientists then used an advanced technique to cut away the faulty section of DNA from a stem cell and replace it with a corrected one, according to the journal.The stem cells went on to produce fresh and healthy liver cells with normal protein levels.Scientists put the new liver cells into mice and found that they worked very well.

  Stem cells are the life source of all other cells in the body.They could transform medicine, providing treatment for blindness, spinal cord injuries and other serous injuries.They could also be used to produce new cells for damaged organs.

  David Lomas, a Cambridge biology professor who worked on the team, said: “If we can use a patient's own skins cells to produce liver cells that we can put back into the patient, we may prevent the future need for transplantation.”

(1)

what is the best title of this passage?

[  ]

A.

How to transplant liver for patients

B.

A new way to transplant livers for patients

C.

The difficulty in curing liver patients

D.

New life for liver patients

(2)

The first paragraph is written to ________.

[  ]

A.

show how difficult it is to cure liver disease

B.

tell us what a liver transplant involves

C.

introduce a potential cure for liver disease

D.

show how serious liver disease can be

(3)

Why do some people get liver cirrhosis according to the article?

[  ]

A.

Because their bodies are lacking in alphal-antitrypsin.

B.

Because their skin cells are not able to protect against inflammation.

C.

Because the alphal-antitrypsin in their bodies is changed or damaged.

D.

Because their liver releases too high a level of protein.

(4)

According to British scientists, liver transplant might ________.

[  ]

A.

become history sooner or later

B.

be replaced by a new stem cell technique in five years

C.

be the only possible cure liver disease in the future

D.

be prevented in the future

(5)

What can be inferred from the passage?

[  ]

A.

Stem cells can keep liver cells healthy and fresh.

B.

Equaling medicine, stem cells can cure blindness, spinal cord injuries and other serous injuries

C.

Stem cells can replace the damaged organs.

D.

All other cells in the body can't work well without stem cells

  Nowadays more and more people are talking about genetically modified foods(GM foods).GM foods develop from genetically modified organisms(有机体), which have had specific changes introduced into their DNA by genetic engineering techniques.These techniques are much more precise where an organis m is exposed to chemicals to create a non-specific but stable change.For many people, the high-tech production raises all kinds of environmental, ethical(伦理的), health and safety problems.Particularly in countries with long farming traditions, the idea seems against nature.

  In fact, GM foods are already very much a part of our lives.They were first put on the market in 1996.A third of the corn and more than half the cotton grown in the U.S.last year was the product of biotechnology, according to the Department of Agriculture.More than 65 million acres of genetically modified crops will be planted in the U.S.this year.The genetic genie is out of the bottle.

  However, like any new product entering the food chain, GM foods must be subjected to careful testing.In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs.In developing countries desperate to feed fast-growing and underfed populations, the matter is simpler and much more urgent:do the benefits of biotech outweigh the risks?

  The statistics on population growth and hunger are disturbing.Last year the world ' s population reached 6 billion.The U.N.states that nearly 800 million people around the world are unhealthy.About 400 million women of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.

  How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values.Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops.Biotech can also improve farming productivity in places where food shortages are caused by prop damage attributable to drought, poor soil and crop viruses.

(1)

The passage mainly talks about ________.

[  ]

A.

the world' s food problem

B.

the development in biotech

C.

the genetically modified foods

D.

the way to solve food shortages

(2)

According to the passage, GM foods ________.

[  ]

A.

will replace naturally grown foods

B.

are far better than naturally grown foods

C.

may help to solve the problem of poor nutrition

D.

can cause serious trouble in developing countries

(3)

The underlined sentence "The genetic genie is out of the bottle." in Paragraph 2 probably means that ________.

[  ]

A.

GM foods are available everywhere

B.

the technology in producing GM foods is advanced

C.

genetic technology may have uncontrollable powers

D.

genetic technology has come out of laboratories into markets

(4)

What' s the writer' s attitude towards GM foods?

[  ]

A.

Enthusiastic.

B.

Cautious.

C.

Disapproving.

D.

Unbelievable.

In my own life, I have experienced many open acts of prejudice (偏见).I remember a time, at age 17 —— I worked as a waiter, and I heard a father tell his little boy that if he did not do well in school, he would end up like me.I have also witnessed the same treatment of my family and friends, so I know what it’s like, and I should have known better.
But now, living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been, and to lose sight of where I want to be going.That blind woman on the streets of Washington, D.C., cured me of my blindness.She reminded me of my belief in humility and to always keep my eyes and heart open.By the way, I helped that lady to the post office.And in writing this essay, I hope to thank her for the priceless lesson.
