Film cameras and digital cameras work in a similar way.
Film cameras
After all, a film camera is basically a light – proof (不透光的) box. It has a lens (镜头) system to focus light onto the film at the back of the camera.
Let’s suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter open for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed (反向的)image on the film.
When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog!
Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.
Digital cameras
In digital cameras, the light falls not on film but onto a sensor (传感器)called a CCD (Charge Coupled Device). This digitally converts(转变) light and colour into a digital information or pixels (象素). The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is.

A．light goes into the camera lens and hits the shutter
B．you haven’t aimed the camera at the dog
C．the image of the dog is not created
D．the sensor fails to convert light and colour into a digital information
69．The main reason that sports photographers can get clear and big photos of players is that _ ___.
A．they use digital cameras B．the lens of their cameras is excellent
C．their focus lenses are short D．their focus lenses are long
70．Generally speaking, a digital camera’s price is ____.

Joe came to New York from the Middle West, dreaming about painting. Delia came to New York from the South, dreaming about music. Joe and Delia met in a studio. Before long they were good friends and got married.
They had only a small flat to live in, but they were happy. They loved each other, and they were both interested in art. Everything was fine until one day they found they had spent all their money.
Delia decided to give music lessons. One afternoon she said to her husband:
“Joe, I’ve found a pupil, a general’s daughter. She is a sweet girl. I’m to give three lessons a week and get $5 a lesson.”
But Joe was not glad.
“But how about me?” he said.” Do you think I’m going to watch you work while I play with my art? No, I want to earn some money too.”
“Joe, , you are silly,” said Delia. “You must keep at your studies. We can live quite happily on $15 a week.”
“Well, perhaps I can sell some of my pictures,” said Joe.
Every day they parted in the morning and met in the evening. A week passed and Delia brought home fifteen dollars, but she looked a little tired.
“Clementina sometimes gets on my nerves. I’m afraid she doesn’t practice enough. But the general is the best old man! I wish you could know him, Joe.”
And then Joe took eighteen dollars out of his pocket.
“I’ve sold one of my pictures to a man from Peoria,” he said, “and he has ordered another.”
“I’m so glad,” said Delia. “Thirty-three dollars! We never had so much to spend before. We’ll have a good supper tonight.”
Next week Joe came home and put another eighteen dollars on the table. In half an hour Delia came, her right hand in a bandage.
“What’s the matter with your hand?” said Joe. Delia laughed and said:
“Oh, a funny thing happened! Clemantina gave me a plate of soup and spilled some of it on my hand. She was very sorry for it. And so was the old general. But why are you looking at me like that, Joe?”
“What time this afternoon did you burn your hand, Delia?”
“Five o’clock, I think. The iron-I mean the soup-was ready about five, Why?”
“Delia, come and sit here,” said Joe. He drew her to the couch and sat beside her.
“What do you do every day, Delia? Do you really give music lesson? Tell me the truth.”
She began to cry.
“I couldn’t get any pupils,” she said, “So I got a place in a laundry ironing shirts. This afternoon a girl accidentally set down an iron on my hand and I got a bad burn. But tell me, Joe, how did you guess that I wasn’t giving music lessons?”
“It’s very simple,” said Joe. “I knew all about your bandages because I had to send them upstairs to a girl in the laundry who had an accident with a hot iron. You see, I work in the engine-room of the same laundry where you work.”
“And your pictures? Did you sell any to that man from Peoria?”
“Well, your general with his Clemantina is an invention, and so is my man from Peoria.”
And then they both laughed. To support the family, Delia worked as .

Famous centenarians (百岁老人) still active in arts, science are in no mood to retire. "Those who stand still, die." is one of Oliveira's favorite phrases. He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession. Every year, Oliveira shoots a film and is currently working on his next project. "You have to work, work, work in order to forget that death is not far away," he said. When asked about his age, Oliveira said with some humility: "It's down to mother nature. It gave to me what it took from others."
Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character. Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens.
Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation.
Another master in his profession is the architect Oscar Niemeyer. The 103-year-old Brazilian is best known for his futuristic-looking buildings in Brasilia, but he also speaks out on behalf of the poor. "The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently. He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder (胆囊) operation he composed a samba tune (桑巴舞曲) in the clinic.
Another man who could sing a song about age is 107-year-old Heesters. The Dutch-born opera singer spent most of his life performing in Germany, where he still works. Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing. "Should I just sit at home and wait until they come and pick me up?" Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role".
Italian scientist Rita Levi-Montalcini, who is 101-year-old and is still active in medical science, has described the force that keeps driving her on: "Progress is created through imperfection." In 1986 she and her lab colleague were awarded the Nobel Prize for Medicine for their work on nerve growth factor. She's convinced that humans grow on challenges.
With so many brilliant examples given, we can see clearly that age is no barrier to some high achievers. From the first two paragraphs, we can see ______.
| A．being active at 102 is achievable for everybody |
| B．Oliveira owes his long life to his mother’s help |
| C．social skills and wisdom are difficult for the senior |
| D．being fit in old age is a matter of luck and character |
How many centenarians are mentioned in this passage?
| A．4 | B．5 | C．6 | D．7 |
By saying "Should I just sit at home and wait until they come and pick me up?” in paragraph 5, Heesters shows us he ________.
| A．wants to sit or lie in comfort |
| B．is waiting for people to pick him up |
| C．is willing to work till he dies |
| D．prefers to give performance at home |
In the passage so many examples were given to show ________.
| A．old age is a big problem if you want tosucceed |
| B．old age can not prevent a great person from achieving a lot |
| C．old people should never think of themselves as old |
| D．as a senior citizen, you have to be open-minded and optimistic |
In the writer’s opinion, the architect Oscar Niemeyer is not ________.
| A．pessimistic | B．intelligent |
| C．positive | D．diligent |

Generations of Americans have been brought up to believe that a good breakfast is essential to one’s life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn’t have breakfast increased by 33%—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America.
For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting (省略) breakfast. “Going without breakfast does not affect work,” said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve work.”
Scientific evidence linking breakfast to better health or better work is surprisingly little, and most of the recent work involves children, not grown-ups. “The literature,” says one researcher, Dr Earnest Polite at the University of Texas, “is poor.” For those who do not take breakfast, the good news is that _______.
| A．several studies have been done in the past few years |
| B．eating little in the morning is good for health |
| C．the omission of breakfast has little effect on one’s work |
| D．grown-ups have especially made studies in this field |
The sentence in paragraph 3 “nor does giving people breakfast improve work” means _______.
| A．people without breakfast can improve their work |
| B．having breakfast does not improve work, either |
| C．not giving people breakfast improves work |
| D．people having breakfast do improve their work, too |
The word "literature" in the last sentence refers to _______.
| A．stories, poems, play, etc |
| B．the films about the breakfast |
| C．newspaper articles or novels |
| D．written works on a topic |
What is implied in the passage is that _______.
| A．Breakfast does not affect work |
| B．Dr Polite works at Market Research Corporation |
| C．Not eating breakfast might affect the health of children |
| D．Professor Bender once taught college courses in nutrition in Chicago |
The main idea of the passage is that _______.
| A．breakfast has nothing to do with people’s health |
| B．breakfast is not as important as we thought before |
| C．breakfast is not as important to us as gasoline to a car |
| D．a good breakfast used to be important to us |
“I once hoped to afford a wonderful telescope, but now I wish my father would be back.” Lucy Lawrence’s letter to Father Christmas written after his father had been knifed to death outside his school gate, must have touched every heart. Lucy went on to say that without his father he couldn’t see the stars in the sky. When those whom we love depart from us, we cannot see the stars for a while.
But Lucy, the stars are still there, and one day, when you are older and your tears have gone ,you will see them again . And, in a strange way, I expect that you will find your father is there too, in your mind and in your heart . I find that my parents , long dead now , still occur in many of my dreams and that I think of them perhaps more than I ever did when they were alive . I still live to please them and I’m still surprised by their reactions. I remember that when I became a professor , I was so proud , or rather so pleased with myself , that I couldn’t wait to write to my parents . The reply was a long time in coming, but when it did, all Mother said was “I hope this means that now you will have more time for the children! ” I haven’t forgotten. The values of my parents still live on.
It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care. Would I have been as ready as Philip Lawrence have been to face the aggressors, and to lay down my life for those in my care ? How many people would want me back for Christmas? It’s a serious thought, one to give me pause.
I pray silently , sometimes , in the dead of night ,that ancient cry of a poet “Deliver my soul from the sword（剑）, and my darling from the power of the evil .” Yet I know the death comes to us all, and sometimes comes suddenly. We must therefore plan to live forever, but live as if we will die tomorrow. We live on, I’m sure, in the lives of those we loved, and therefore we ought to have a care for what they will remember and what they will treasure. If more parents knew this in their hearts to be true, there might be fewer knives on our streets today.According to the whole text we can see that the first paragraph .
