第三部分阅读理解(共20小题;每小题2分,满分40分)

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项

A

Last year.I took a sightseeing trip to Washington, DC.I heard a voice say, “Can you help me?” When I turned around, I saw an elderly blind woman with her hand extended.Immediately, I pulled out all of my change and placed it on her hand without even looking at her.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 acted with prejudice―I judged another person simply for what I assumed she had to be.I hated what I saw in myself.

The thing I had forgotten about myself is that I am an immigrant.I left Honduras and arrived in the US at the age of 15.I started my new life with two suitcases,my brother and sister.Through the years, I have been a doorkeeper, cashier and pizza delivery driver among many other humble(卑微的)jobs, and eventually I became a network engineer.

In my own life, I have experienced prejudice.I remember a time―at the age of 17―when I was a busboy, I heard a father tell his little boy that if he did not do well in school, he would end up like me.

But now, living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am, where I have been ,and to lose sight of where I want to be going.That blind woman on the streets cured me of my blindness.She reminded me of my belief in humility(谦虚).By the way, I helped that lady to the post office.I hope to thank her for the priceless lesson.

56.How did the writer give the blind woman money?

A.In a modest way            B.In a polite way

C.In an impatient way.     D.In a painful way

57According to the text, the writer__________.

A.still lives a poor life         B.was busy with his work

C.was born in Honduras        D.was a native of Washington D.C.

58.According to the text, the author most probably agrees that one should__________.

A.be nice to the elderly and the disabled

B.try to experience different kinds of culture

C.treat others equally with love and respect

D.think about one’s past as often as possible

59.What would be the best title of the text?

A.A priceless lesson    B.An act of prejudice

C.A sightseeing trip    D.A humble moment

题型:单项选择题

The field of medicine has always attracted its share of quacks and charlatans — disrepu-table women and men with little or no medical knowledge who promise quick cures at cheap prices. The reasons why quackery thrives even in modem times are easy to find.
To begin with, pain seems to be a chronic human condition. A person whose body or mind "hurts" will often pay any amount of money for the promise of relief. Second, even the best medical treatment cannot cure all the ills that beset men and women. People who mistrust or dislike the truths that their physicians tell them often turn to more sympathetic ears.
Many people lack the training necessary to evaluate medical claims. Given the choice between (a) a reputable physician who says a cure for cancer will be long, expensive and may not work at all, and (b) a salesperson who says that several bottles of a secret formula "snake oil" will cure not only cancer but tuberculosis as well, some individuals will opt for "snake oil".
Many "snake oil" remedies are highly laced with alcohol or narcotic drugs. Anyone who drinks them may get so drunk or stoned that they drown their pains in the rising tide of pleasant intoxication. Little wonder that "snake oil" is a popular cure-all for minor aches and hurts! But let there be no misunderstandings. A very few "home remedies" actually work. However, most remedies sold by quacks are not only useless, but often can be harmful as well.

People who seek the advice of quacks and charlatans are those who______.

A.are poorly educated

B.are highly educated

C.dislike medical treatments

D.mistrust physicians’ truths
