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.
67．Which of the following statements is TRUE?
A．Both digital and film cameras focus light onto the film.
B．All cameras have a sensor.
C．Digital cameras and film cameras have something in common. .
D．Small cameras usually have longer focal lengths.
68．In the “Film cameras” part, you fail to take the picture of the dog because _____.
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 ____.
A．closely related to the quality of the CCD
B．irrelevant to the quality of the CCD
C．closely related to the lens
D．irrelevant to the lens

LONDON: What could possibly be wrong with planting trees? The benefits are obvious; they firm the soil, soak up (摄取) extra water and take carbon dioxide (二氧化碳) our of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly that the complexity of the system and the importance of not tinkering(粗劣地修补) with it without understanding the results. For this reason the need is to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超过) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again.
Solutions to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.
63．People usually hold the opinion that .
A．huge dust storms can destroy carbon dioxide
B．huge dust storms can destroy the oceans on the earth
C．huge dust storms can’t do anything beneficial for man
D．planting trees is the only way to control huge dust storms
64．Andy Ridgwell, the environmental scientist, believes that .
A．dust plays a more important part than trees
B．trees should’t have been planted in dry places
C．carbon dioxide is harmful to everything on the earth
D．environmental problems are more complex than expected
65．Robert Jackson’s experiment proves that .
A．grassland areas should be covered by forests
B．trees hold more carbon than grasses
C．carbon can turn grass into dust
D．less carbon can make trees grow faster
66．The underlined word “combat” in the last paragraph means .
A．learn about B．fight against C．live with D．give up

Compassion (同情) is a desire within us to help others. With effort, we can translate compassion into actions. An experience last weekend showed me this is true. I work part—time in a supermarket across from a building for the elderly. These old people are our main customers，and it’s easy to lose patience over their slowness. But last Sunday，one aged gentleman appeared to teach me a valuable lesson. This untidy marl walked up to my register with a box of biscuits. He said he was out of cash，had just moved into his room，and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day.
I couldn’t help staring at him. I wondered what kind of person he had been ten or twenty years before，and what he would be like if luck had gone his way. I had a hurt in my heart for this kind of human soul，all alone in the world. I told him that I was sorry，and the store rules didn’t allow me to do so. I felt stupid and unkind saying this，but I valued my job.
Just then，another man，standing behind the first，spoke up. if anything，he looked more pitiable, “Charge it to me,” was all he said.
What I had been feeling was pity. Pity is soft，safe and easy. Compassion，on the other hand，is caring in action. I thanked the second man but told him that was not allowed，either. Then I reached into my pocket and paid for the biscuits myself I reached into my pocket because these two men had reached into my heart and taught me compassion.
59．The aged gentleman who wanted to buy the biscuits .
A．promised to obey the store rules
B．forgot to take any money with him
C．hoped to have the food first and pay later
D．could not afford anything more expensive
60．Which of the following best describes the old gentleman?
A．kind and lucky B．poor and lonely
C．friendly and helpful D．hum and disappointed
61．The writer followed the store rules because .
A．he wanted to keep his present job
B．he felt no pity for the old gentleman
C．he considered the old gentleman dishonest
D．he expected someone else to pay for the old gentleman
62．What does the writer 1earn from his experience?
A．Wealth is most important than anything else.
B．Helping others is easier said than done.
C．Experience is better gained through practice.
D．Obeying the rules means more than compassion.

Last week my youngest son and I visited my father at his new home in Tucson, Arizona he moved there a few years ago, and I was eager to see his new place and meet his friends.
My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him; as a school girl and young adult I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?
The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. In his new home in Arizona, my dad is back to me from where he was.

Wrting artieles about films for The Front Page was my first proper job. Before then I had done bits of reviewing --- novels for other newspapers, films for a magazine and anything I was asked to do for the radio．That was how I met Tom Seaton, the first arts editor of The Front Page, who had also written for television．He hired me, but Tom was not primarily a journalist, or he would certainly have been more careful in choosing his staff．
At first, his idea was that a team of critics should take care of the art forms that didn’t require specialized knowledge: books, TV, theatre, film and radio．There would be a weekly lunch at which we would make our choices from the artistic material that Tom had decided we should cover, though there would also be guests to make the atmosphere sociable．
It all felt like a bit of dream at that time: a new newspaper and I was one of the team．It seemed so unlikely that a paper could be introduced into a crowded market．It seemed just as likely that a millionaire wanted to help me personally, and was pretending to employ me．Such was my lack of self-confidence．
Tom’s original scheme for a team of critics for the arts never took off．It was a good idea, but we didn’t get together as planned and so everything was done by phone．It turned out, too, that the general public out there preferred to associate a reviewer with a single subject area, and so I chose film．Without Tom’s initial push, though, we would hardly have come up with the present arrangement, by which I write an extended weekly piece, usually on one film．
The space I am given allows me to broaden my argument --- or forces me, in an uninteresting week, to make something out of nothing．But what is my role in the public arena? I assume that people choose what films to go to on the basis of the stars, the publicity or the director．So if a film review isn’t really a consumer guide, what is it? I certainly don’t feel I have a responsibility to be ‘right’ about a movie．Nor do I think there should be a certain number of ‘great’ and ‘bad’ films each year．All I have to do is put forward an argument．I’m not a judge, and nor would I want to be．
67．What do we learn about Tom Seaton from the first paragraph?
A．He encouraged Mark to become a writer．
B．He had worked in various areas of the media．
C．He met Mark when working for television．
D．He prefers to employ people that he knows．
68．The weekly lunches were planned in order to .
A．help the writers get to know each other
B．provide an informal information session
C．distribute the work that had to be done
D．entertain important visitors from the arts
69．What does the author mean when he says that Tom’s plan ‘never took off’ in Paragraph 4?
A．It was unpopular.
B．It wasted too much time.
C．It wasn’t planned properly.
D．It wasn’t put into practice.
70．Which of the following best describes what Mark says about his work?
A．His success varies from year to year．
B．He prefers to write about films he likes．
C．He can freely express his opinion．
D．He writes according to accepted rules．
