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．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 |

| C．treat others equally with love and respect |
| D．think about one’s past as often as possible |

| C．A sightseeing trip | D．A humble moment |
It was a Sunday morning, and I was in a terrible mood. Two of my friends had gone to the movies the night before and hadn’t invited me. I was in my room thinking of ways to make them sorry when my father came in. “Want to go for a ride, today, Beck? It’s a beautiful day.”
“No! Leave me alone!” Those were the last words I said to him that morning.
My friends called and invited me to go to the mall with them a few hours later. I forgot to be mad at them and went. I came home to find a note on the table. My mother put it where I would be sure to see it. “Dad has had an accident. Please meet us at Highland Park Hospital”.
When I reached the hospital, my mother came out and told me my father’s injuries were extensive. “Your father told the driver to leave him alone and just call 911, thank God! If he had moved Daddy, there’s no telling what might have happened. A broken rib (肋骨) might have pierced (穿透) a lung....”
My mother may have said more, but I didn’t hear. I didn’t hear anything except those terrible words: Leave me alone. My dad said them to save himself from being hurt more. How much had I hurt him when I hurled (愤慨地说出) those words at him earlier in the day?
It was several days later that he was finally able to have a conversation. I held his hand gently, afraid of hurting him.
“Daddy... I am so sorry....”
“It’s okay, sweetheart. I’ll be okay.”
“No,” I said, “I mean about what I said to you that day. You know, that morning?”
My father could no more tell a lie than he could fly. He looked at me and said, “Sweetheart, I don’t remember anything about that day, not before, during or after the accident. I remember kissing you goodnight the night before, though.” He managed a weak smile.
My English teacher once told me that words have immeasurable power. They can hurt or they can heal. And we all have the power to choose our words. I intend to do that very carefully from now on.The author was in bad mood that morning because ________.
| A．his father had a terrible accident |
| B．he couldn’t drive to the mall with his friends |
| C．his friends hadn’t invited him to the cinema |
| D．his father didn’t allow him to go out with his friends |
Why did the author say sorry to his father in the hospital?
| A．Because he didn’t go along with his father. |
| B．Because he was rude to his father that morning. |
| C．Because he failed to come earlier after the accident. |
| D．Because he couldn’t look after his father in the hospital. |
The reason why the author’s father said he forgot everything about that day is that ________.
| A．he had a poor memory |
| B．he didn’t want to forgive his son |
| C．he just wanted to comfort his son |
| D．he lost his memory after the accident |
What lesson did Beck learn from the matter?

| B．Don’t hurt others with rude words |
| C．Don’t move the injured in an accident |
| D．Don’t be angry with friends at small things |
Scientists who discovered a new way of generating electricity from water say they may have come across an alternative source of clean energy to rival wind and solar power.
The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter(滤水器)that contained thousands of narrow channels lined up side by side. “When we took a syringe(注射器)of water and squeezed it through the filter, we got enough power to light a light bulb,” said Larry Kostiuk of the University of Alberta in Canada. “The harder you push the syringe, the more electric current you get.”
The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions(阳离子)fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. “The last time someone came up with a way of generating electricity was Michael Faraday in 1839,” he said. “So this is the first new way of generating electricity in 160 years, which is why we are so excited about it.”
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. “You’d need to be sure it wouldn’t leak, and you’d need to make sure it wouldn’t freeze,” he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. “It could compete with wind and solar power,” he added.What does the passage mainly want to tell us about?
| A．A kind of solar power discovered by scientists. |
| B．A kind of new energy source found in tap water. |
| C．The breakthrough to generate electricity 160 yeas ago. |
| D．A kind of new battery invented without poisonous substances. |
The underlined word “repels” in Paragraph 4 is closest in meaning to _________.
| A．rejects | B．identifies | C．attracts | D．rebels |
Why were the scientists extremely happy about their new discovery?
| A．They were the first to find a new way to produce electricity. |
| B．They could make an electric current to light a light bulb. |
| C．Their discovery could be used to invent water batteries. |
| D．Their discovery was made 160 years earlier than Faraday’s. |
What can we infer about potential water batteries?
| A．They must be used to power mobile phones and calculators. |
| B．They have some possible disadvantages like water leaking. |
| C．They would be needed greatly at city water filtration sites. |
| D．They would be better than wind and solar power. |

In Africa, listening is a guiding principle .It’s a principle that’ been lost in the constant chat of the Western world .From my own past experience , I noticed how much faster I had to answer a question during a TV interview .It is as if we have completely lost the ability to listen .We talk and talk , and we end up frightened by silence .
Everywhere, people on the African continent write and tell stories. Even the nomads(流浪者)who still live in the Kalahari Desert are said to tell one another stories on their daylong wanderings, during which they search for roots and animals to hunt.
A number of years ago I sat down on a stone bench outside the Teatro Avenida in Maputo, Mozambique, where I worked as an artistic consultant. It was a hot day, and we were taking a break, hoping that a cool gentle wind would move past. Two old African men were sitting on that bench, but there was room for me, too. In Africa people share more than just water. Even when it comes to shade, people are generous.
I heard the two men talking about a third old man who had recently died. One of them said, “I was visiting him at his home. He started to tell me an amazing story about something that had happened to him when he was young. But it was a long story. Night came, and I decided that I should come back the next day to hear the rest. But when I arrived, he was dead.”
The man fell silent. I decided not to leave that bench until I heard how the other man would respond to what he’d heard. Finally he, too, spoke. “That’s not a good way to die—before you’ve told the end of your story.”
What separates us from animals is the fact that we are storytelling creatures and we can listen to other people’s dreams, fears, joys, sorrows, desires and defeats—and they in turn can listen to ours.
Many people make the mistake of confusing information with knowledge. They are not the same thing. Knowledge involves the interpretation of information. Knowledge involves listening.
Many words will be written on the wind and the sand, or end up in store. But the storytelling will go on until the last human being stops listening. Then we can send the great record of human out into the endless universe.
Who knows? Maybe someone is out there, willing to listen…From the very beginning of the passage, we can know Europeans ________.
| A．actually lose the ability to listen |
| B．seldom chat constantly with each other |
| C．feel frightened when they are alone and silent |
| D．tend to talk more and listen less |
It can be inferred from the passage that if you are in Africa, you will _______.
| A．suffer hot weather and lack of water |
| B．be certainly helped when in trouble |
| C．often hear the stories told by strangers |
| D．have no choice but to listen during a talk |
According to the last three paragraphs, we can know _________.
| A．no one knows exactly why Africans are willing to listen |
| B．information is hard to understand without interpretation |
| C．listening makes the difference between information and knowledge |
| D．the existence of humans’ recordings totally depends on the way of storytelling |
The passage mainly talks about __________.
| A．the experience of the author |
| B．the art of listening in Africa |
| C．the importance of storytelling |
| D．the life styles of Africans |
A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. What is the passage mainly about?
| A．Teens’ sleep is linked to their relationship with people around them. |
| B．Lack of adequate sleep puts teens at risk of many bad consequences. |
| C．Modern technology has something to do with teens’ sleep problems. |
| D．It is necessary for teens to join in sports and positive social activities. |
According to Maume’s analysis, who will probably have a poor night’s sleep?
| A．Teens who feel like talking with their parents. |
| B．Teens who have friends sharing their dreams. |
| C．Teens who feel contented about themselves. |
| D．Teens who lack a sense of security at school. |
Para 5 functions as .
| A．a comparison | B．an introduction | C．a conclusion | D．an addition |
Parents are supposed to when their kids are growing up.
| A．continue their broken marriage |
| B．allow children to decide when to sleep |
| C．limit teens’ using new technology |
| D．force teens to have 10 hours’ sleep daily |
