In 1956 Phoenix, Arizona, was a city with boundless blue skies. One day as I walked around the house with my sister Kathy’s new parakeet (小鹦鹉)on my finger, I wanted to show Perky 16_____ the sky looked like. Maybe he could make a little bird friend out there. I took him into the backyard, and then, to my 17______, Perky flew off. The enormous(巨大的), blue sky swallowed up my sister’s blue  treasure and suddenly he had gone, clipped wings and all.
Kathy managed to forgive me. With fake optimism(乐观), she even tried to reassure (安慰)me that Perky would find a new  18 ______. But I was far too clever to 19______ that such a thing was possible.
Decades later, I watched my own 20_______ growing. We shared their activities, spending soccer Saturdays in folding chairs with the parents of the kids’ friends, the Kissells. The two families went camping around Arizona together. We became the best of friends. One evening, the game was to tell Great Pet stories. One person claimed(宣称) to 21______ the oldest living goldfish. Someone else had a psychic dog. Then Barry, the father of the other family, took the floor and 22 ________ that the Greatest Pet of All Time was his blue parakeet, Sweetie Pie.
"The best thing 23______ Sweetie Pie," he said, "was the way we got him. One day, when I was about eight, out of the clear, blue sky, a little blue parakeet just floated down and landed on my finger."
When I was finally able to 24_______ , we examined the amazing evidence(证据). The dates and the locations and the pictures of the bird all matched up. It seems our two families had been connected long before we ever met. Forty years later, I ran to my sister and said, "You were 25_______! Perky lived!"

For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more    41    than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to    42     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists    43    that every modern house has some kind of indoor pollution. People began to    44    the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that    45    the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to    46    harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control    47    for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen    48    its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each    49    different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.

原创(十)【原创精品】
During the years of depression(萧条), food and money were very hard to find and people had to trade things with each other.
One day I was   36  some potatoes from Mr Miller. I noticed a small poor boy hungrily   37   a full basket of   38   green peas. Then I was  39  to see that Mr Miller sold the boy a bag of peas   for just a marble (弹球).
Mrs Miller, who had been standing nearby,   40  and told me that Mr Miller loved to trade with the three boys in the village for peas, tomatoes, and other things  41  he didn’t really need any marbles. I left the stand, smiling to myself,   42   by this man.
Several years went by. One day I learned that Mr Miller had died. I took part in the funeral(葬礼),  43   three young men . They came over to Mrs Miller, hugged her, kissed her on the cheek, spoke with her and moved on,   44  their eyes.
Our 45  came to meet Mrs Miller. I mentioned 46   she had told me about the 47 . She told me,“Those three young men above were the boys I told you about. They just told me   48  they appreciated the things Jim‘traded’with them. Now, at last, they came to pay their debt.”
“We’ve 49  had a great deal of the wealth in this world,” she added, “but right now, Jim would consider himself to be the  50   man.”
Then she gently lifted the   51   fingers of her husband. Resting underneath were three red marbles.
At that time I realized that we would not be  52   by our words, but by our kind  53  . It is said that it takes a minute to find a    54  person, an hour to appreciate him, a day to love him, but an entire life to  55  him.
