We each have a memory（记忆力）. That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.
| A．they always sleep very well | B．they often eat good food |
| C．they read a lot of books | D．they have very good memories |
| A．at the age of six | B．when he is a small child |
| C．after he goes to school | D．when he can read and write |
| A．read and write | B．make sentences |
| C．hear and remember the sounds | D．think hard |
| A．they have no good memories | B．they have no recorders |
| C．they have too much time for it | D．they are busy with other subjects |
| A．if you have plenty of good food |
| B．if you do more and more exercises |
| C．if you do morning exercises every day |
| D．if you get up early |

A
Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

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
C
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
B
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.
