Then we walked slowly in the garden, hand in hand, to have a last look at each rock, each tree, each flower. We sat for a while by the small pond which was a favorite place of my grandpa's. "What do you see here, Tommy？" asked the old man. I looked at the water, not knowing what to say, and then replied, "I see something soft and beautiful, Grandpa." He pulled me close to him and said, "It isn't the pond or the trees or the flowers that are beautiful. It is the special place in your heart that makes you feel so." After a while, he continued, "I built the pond, and planted the trees and the flowers a long time ago. I started to build this beautiful home the day my only son was born." He stopped. After a long silence, he murmured(低声说), "One day a terrible war came, and my son, like many other people's sons, went away to fight. Five months later, a telegram came, telling us that my son had passed away...' he couldn't finish his sentence. I saw tears trickle from his eyes. "That afternoon I picked some roses from this place and put them in front of son's portrait (肖像), and said goodbye to him. You know who he was, Tommy？"
"My father？" I asked in a whisper, hoping my grandpa would say no. But he said, "That's rights my dear. ' Ann in arm, we cried. Then the old man held me ups and said softly, "My dear Tom, we axe going to move, but don't say good-bye to our old house, never."

Lillehammer's opening ceremonies featured a giant Olympic Torch burning biogas produced by rotting vegetation. During construction, builders were threatened with $7,500 fines for felling trees unnecessarily. Rare trees were carefully transplanted from hillsides. Food is being served on potato-based plates that will be fed, in turn, to pigs. Smoking has been banned outdoors as well as in, with enforcement by polite requests.
Environmentalists have declared partial victory: though Coca-Cola's plan to decorate the town with banners has been scaled back, there are still too many billboards for strict green tastes. Perhaps, but after the Games, athlete housing will be converted into vacation homes or shipped to the northlands for student dormitories. Bullets will be plucked from biathlon targets and recycled to keep the lead from poisoning ground water. And these tricks won't be forgotten. Embarrassed by environmental protests, the I. O. C. claims that green awareness is now entrenched—along with sport and culture—as a permanent dimension of the Olympic Charter.
Indeed, Sydney was successful in becoming host for the 2000 Summer Games in part on the strength of its endorsement from Greenpeace. Aspiring host cities are picking up the code. Salt Lake City, bidding for the 2002 Games, may opt to use the bobsled run that Calgary built for the '88 Games. After that, who could deny that recycling is an Olympic movement？
Which of the following countries has not paid enough attention to the "green" issues？
A．Norway.
B．France.
C．America.
D．Australia.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. (78)In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he bad. And besides, be is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil—allowing the rain to sink in—and also bind the soil, thus preventing it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing remains but worthless desert.
Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It set up the empire but, without its trees, its soil became poor and it grew weak. When the empire fell to pieces, the home country found itself faced with floods and starvation.

One summer evening I was sitting by the open window, reading a good science storybook. (79)I was so interested in the story I was reading that I did not notice that it was getting dark. When I realized it was too dark for me to read easily, I put the book down and got up to turn on the light. Just then I heard someone crying, "Help! Help!" it seemed to come from the trees at the other end of the yard. (80)I looked out but it was now too dark to see anything clearly. Almost immediately I heard the cry again. It sounded like a child, but I could not imagine what anybody could be doing in our backyard, unless one of the neighborhood children had climbed a tree and had not been able to get down.
I decided that I should go out and have a look in the yard, just in case someone was in trouble. I turned on the light and found for myself a flashlight and a baseball bat in the room. I thought they might be useful. Armed with these, I went out into the yard. Once again I heard the cry and this time there was no doubt that it came from the trees at the far end of the yard. "Who's there？" I called out as I walked across the yard towards the trees. But there was no answer. With the help of my flashlight, I searched all over that end of the yard, including the branches of the tree. There was no sign of anybody or anything. I came to the conclusion that my imagination was playing tricks on me, probably because of the story I was reading about strange creatures on another planet.
Feeling rather foolish about hunting around in my own backyard with a baseball bat, I went back into the house and put the bat and the flashlight away. I had just sat down to read my book again when I was frightened by the cry of "Help! Help!" from right behind me. I dropped my book and jumped up. There, sitting on the table was a large green and red bird. It was my neighbor's parrot(鹦鹉)!While I was out in the yard, the parrot must have seen the light in the living room and come in through the open window.

NASA's Darrel Williams speaks about the Landsat 7 Project. He said that an eruption caused trees to burn up in a large forest. Fifteen years later, pinkish images from space show that the trees and plant life are growing again. Williams says that clear-cut areas easily show up in the pictures. He wants Americans to look at how much land is being cleared of forests in our country.
Satellites have provided other information about changes on earth. In the past ten years, more than four miles have shrunk from glaciers in Alaska. Landsat 7 received these computer images of Glacier Bay in Alaska.
Hurricanes Floyd and Irene have damaged the coastline in North Carolina. Runoff from farms and silt have gone into the ocean according to satellite images. Loss of trees and forests have caused hotter summers in southern cities such as Atlanta, Georgia.
The Landsat 7 images are like pictures in a photo album. Instead of pictures of the family, the album shows changes around the globe in the past 25 years.
A new satellite, Terra, is going to be launched by NASA soon. It will be more advanced that Landsat 7 and will take important global pictures. Ocean temperatures and energy loss will be provided by Terra daily.
Landsat 7 shows how changes have occurred on land by sending back ______.
A．images taken with a Polaroid camera
B．the latest images taken by a government satellite
C．a television camera
D．astronauts
