When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白內(nèi)障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.
小題1:We should take good care of our eyes________.     .
A.only when we can see well
B.only when we cannot see perfectly
C.even if we can see wel
D.only when we realize how important our eyes are

A.obviousB.possibleC.clearD.unclear

小題1:C
小題2:A
小題3:D
小題4:D
眼睛是心靈的窗戶,我們應(yīng)該保護(hù)好我們的眼睛。
小題1:推理題。根據(jù)文章第一段內(nèi)容可知很多人看得見(jiàn)的時(shí)候不重視對(duì)眼睛的保護(hù),只是到了眼睛出了問(wèn)題的時(shí)候才意識(shí)到眼睛的重要性,那么C正確。即使我們能看見(jiàn),我們也要照顧好我們的眼睛。
小題2:推理題。根據(jù)文章第2段第一句People who are near-sighted can only see things that are very close to their eyes.可知當(dāng)看遠(yuǎn)處的東西模糊不清的時(shí)候,我們應(yīng)該是患了近視。
小題3:猜測(cè)詞義題。根據(jù)上文的can only see things that are very close to their eyes.可知是指遠(yuǎn)處的東西看起來(lái)都很模糊不清。D正確。
小題4:推理題。根據(jù)文章最后兩句The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.可知兩只眼睛對(duì)于判斷距離很重要。

Several years ago, while attending a communication course, I experienced a most unusual process. The instructor asked us to list__36__ in our past that we felt __37__ of, regretted, or incomplete about and read our lists aloud.
This seemed like a very __38__ process, but there’s always some __39__soul in the crowd who will volunteer. The instructor then __40__ that we find ways to __41__ people, or take some action to right any wrong doings. I was seriously wondering how this could ever __42__ my communication.
Then the man next to me raised his hand and volunteered this story: “Making my__43__, I remembered an incident from high school. I grew up in a small town. There was a Sheriff __44__ of us kids liked. One night, my two buddies(同伴) and I decided to play a __45__ on him.
After drinking a few beers, we climbed the tall water tank in the middle of the town, and wrote on the tank in bright red paint: Sheriff Brown is a s.o.b. (畜生). The next day, almost the whole town saw our glorious __46__. Within two hours, Sheriff Brown had us in his office. My friends told the truth but I lied. No one __47__ found out.”
“Nearly 20 years later, Sheriff Brown’s name __48__ on my list. I didn’t even know if he was still __49__. Last weekend, I dialed the information in my hometown and found there was a Roger Brown still listed. I tried his number. After a few __50__, I heard, “Hello?” I said, “Sheriff Brown?” Paused. “Yes.” “Well, this is Jimmy Calkins.”
“And I want you to know that I did it.” Paused. “I knew it!” he yelled back. We had a good laugh and a __51__ discussion. His closing words were: “Jimmy, I always felt bad for you __52__ your buddies got it off their chest, but you were carrying it __53__ all these years. I want to thank you for calling me...for your sake.”
Jimmy inspired me to __54__all 101 items on my list within two years, and I always remember what I learned from the course: It’s never too late to __55__the past wrongdoings.

In 1826, a Frenchman named Niepce needed pictures for his business, but he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.
The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. This kind of photograph was called a daguerreotype. Soon, other people began to use Daguerre’s process. In about 1840, the process was improved. Then photographers could take pictures of people and moving things.
Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were very life-like and full of personality.
In the 1880s, new inventions began to change photography. Photographers could buy film ready-made in rolls. And finally, the invention of the small handheld camera made photography less expensive. With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favorite places. They called these pictures “snapshots”.
Photography also turned into a form of art by the end the 19th century, some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.

A.inventing daguerreotype

I fell in love with music from a young age and often sat down making a few songs of my own.What would life be like, I wondered, without a beautiful song? In 1992, I made two love songs to my darling wife and watched tears run down her face as I sang."Sam," she said earnestly, "Your songs should be heard by more people."
She got my ballads and started bothering various media people about me, her singing barber husband.Two radio stations took an interest and played the songs.After the programme was aired, I became known in our community as the Singing Barber.
The biggest surprise, however, was still to come.I received a call from a music promoter who offered me a long-term recording contract.He explained that he would be investing a lot of money to market my songs.I needed to be wholly focused on selling my records all over Australia.

One of my most unforgettable experiences is the day I finished my tough rowing and keep myself free of loneliness.
As the youngest female ever to row alone across the Atlantic Ocean, I was often asked the same question: How did you, a only 20-year old youngster row a 18-foot boat for 70 days through those strong winds and violent waves and survive?
Frankly speaking, for me, the physical challenge was not the greatest one. Before I made my mind to row across the Atlantic, I had already cycled 3,300 miles, run all by myself across the Mojave Desert, and swum the 325-mile length of the Allegheny River. No, the hardest part would be mental: How would I cope with the terrible loneliness and the boredom on the vast sea for such a long time?
I set out on January 1 and my first object was to swim past the quarter-way mark, which would take about 20 days. I made it on January 20, a gray and cloudy day. I had thought to do something to celebrate my first goal such as treating myself to a chocolate bar or something else. But I didn’t. I was suffering from unbearable boredom and loneliness of the long sea journey. I hadn’t seen any landing at least more than two weeks. It seemed to feel the same every day. Eating, rowing, sleeping, staring at the sky, watching the ocean.
Then that day came! It was around dusk, I noticed something move on the horizon. Yes, some dolphins! They approached me and circled my boat. Suddenly I felt so blessed. They had arrived to accompany me and helped to celebrate, just when I needed them so badly! For the next 15 minutes, I did row at full speed with all my strength with those lovely dolphins around. By the time they were to leave me and we went our separate ways, I was no longer lonely.
After 70 days and five hours at sea, I finally reached my final destination. I was proud that I made it, all 2,817 miles, which helped to raise $70,000 for the Blue Planet Run Foundation, an organization for funding drinking water. I’ve been told some athletes struggled to get through just by imagining the end during the whole process. But for me, what makes miracle is to focus your mind on the moment, where you experience the personal growth—those moments of awareness of being connected to the sun, the weather, and the waves. And, on the best day of my life, I had to admit those dolphins really freed myself from terrible loneliness.
小題1:Which of the following belongs to part of preparation for the row?
A.Answering the same question raised by people
B.Swimming the 325-mile length of the river
C.Running 3,300 miles cross-country
D.Biking across the Mojave Desert
小題2:The underlined part means ___________.
A.I wasn’t in the mood to celebrate my first goal
B.I didn’t have any chocolate bar for energy
C.It’s a pity not to celebrate my passing the quarter
D.It’s a pity not to treat myself to a chocolate bar
小題3:What can be implied from the last two paragraphs?
A.The Blue Planet Run Foundation helped me a lot.
B.The dolphins accompanied me to reach my destination
C.The unexpected dolphins swept away my loneliness
D.Imagination was a useful way to help me get through
小題4:Which can be the best title of the passage?
A.The only challenge for a 20-year old
B.Tips on handling loneliness at sea.
C.How to row alone across the Atlantic
D.The day I stopped being lonely

Grandfather was an elder Cherokee Native American who had a wrinkled, nut brown face and kind dark eyes.His grandson often came in the evening to sit on his knee and asked the many questions that children asked.
One day the grandson came to his grandfather with a look of anger on his face and the following story."Father and I went to the store today and because I helped him, he bought me a present, a jack-knife.I went outside to wait for father and to admire my new knife in the sunlight.Some town boys came by and saw me.They surrounded me and started saying bad things.They called me dirty and stupid and said that I should not have such a fine knife.The largest of these boys pushed me back and I fell over one of the other boys.I dropped my knife and one of them picked it up and they all ran away laughing.I hate them.I hate them all.”
The elder Cherokee, with eyes that had seen too much, lifted his grandson's face so his eyes looked into the boy's face.Grandfather said, " Let me tell you a story.I, too, at times, have felt a great hate for those who have taken so much with no sorrow for what they do.But hate wears you down and does not hurt your enemy.It is like drinking poison and wishing your enemy would die.I have struggled with these feelings many times.It is as if two wolves are inside me...It is a terrible fight.
One wolf is good and does no harm.He lives in harmony with all around him and does not take offense (冒犯) when no offense is intended.It will only fight when it is right to do so and in the right way.This wolf stands for joy, peace, love, hope, sharing, modesty, kindness, friendship, sympathy, generosity, truth and faith.
The other wolf is full of anger.The smallest thing will set off his fiercest temper.He fights everyone, all the time, for no reason.He cannot think because his anger and hate are so much.
It is helpless anger, for his anger will change nothing.This wolf represents fear, envy, greed, self-pity, guilt, lies, false pride and superiority.
Sometimes, it is hard to live with these two wolves inside me for both of them try to control my mind.This same fight is going on inside you and inside every other person too."
The boy looked into his grandfather's eyes and asked, "Which wolf will win?" The old Cherokee simply replied ...
"The one you feed."
小題1:The boy was angry because ______.
A.he was not satisfied with his present
B.his back was badly injured in a fight
C.he had waited for his father for too long
D.his jack-knife had been taken away by some boys
小題2:The angry wolf would probably be described as ______.
A.a(chǎn)ggressive(好斗)B.sympatheticC.modestD.unsuccessful
小題3:We can learn from the third paragraph that ______.
A."hate" is healthyB."hate" hurts oneself
C."hate" is complicatedD."hate" harms one's enemies
小題4:What did Grandfather mean by saying "The one you feed" in the last paragraph?
A.We should feed the two wolves equally.
B.Living in harmony with others is important.
C.Our feelings should be expressed at the right time.
D.The choices we make determine who we will become.
