第一篇
As a young man, Aaron was a skilled artist, a potter. He had a wife and two fine sons. One night, his older son developed a stomachache. Thinking it was some
(1) disorder, neither Aaron nor his wife took the condition very seriously. But the illness was actually severe and the boy (2) suddenly that night.
The son's death could have been prevented if he had only (3) the seriousness of the situation! Aaron's emotional health got (4) under the heavy burden of his guilt (内疚). What's worse, his wife left him a short time later, leaving him alone with his six-year-old younger son. The hurt and pain of the two situations were more than Aaron could handle, and he (5) alcohol (酒精) to help him cope. In time Aaron became an alcoholic (酗酒者).
As the alcoholism (酗酒) (6) , Aaron began to lose everything he possessed — his home, his land, his art objects, everything. (7) , Aaron died alone in a San Francisco motel room.
When I heard of Aaron's death, I reacted like most people who show no respect for one ending his life with nothing material to show for it. "What a complete failure!" I thought. "What a (8) life!"
As time went by, I began to reevaluate my earlier cold (9) . You see, I knew Aaron's now adult son, Ernie. He has a family and he is one of the kindest, most caring, most loving men I have ever known. I watched Ernie with his (10) . I saw the free flow of (11) between them. I knew that kindness and consideration had to come from somewhere.
I hadn't heard Ernie talk much about his father. It is so hard to (12) an alcoholic. One day I worked up my courage to (13) him. "I'm really (14) by something," I said." I know your father was basically the only one to (15) you. What on earth did he do to make you become such a special person "
Ernie sat quietly and thought for a few moments. Then he said," From my earliest memories as a child until I left home at 18, Aaron came into my room every night, gave me a (16) and said, 'I love you, son.'"
Tears came to my eyes as I realized what a fool I had been to judge Aaron as a(n) (17) . He had not (18) any material possessions to his son. But he had been a kind loving (19) . He (20) one of the finest, most giving men I have ever known.

The Amazon rainforest is so important that frequently regarded as the “lungs of the planet”. Scientists have found a small number of tree species that are doing the heaviest (1) as they help to (2) global warming.
Their discovery that 182 species (3) half the rainforest wood-bound carbon suggests that the future of the world's climate, and the lines of its coastal areas are (4) with the fate of this small part of about 16,000 Amazonian tree species.
Despite ongoing logging (伐木工作)and recent drought, the Amazon is (5) to perhaps a sixth of the carbon stored in living plants the world over, helping to keep (6) of climate-changing carbon dioxide (7) in the atmosphere.
The Amazon is a particularly important carbon stock, and it's currently (8) a carbon sink,” Sophie Fauset said. ” What we're trying to do is increase our understanding of (9) this carbon is going and which trees are storing it.”
“There are a few species that seem to grow (10) and those are the huge ones you'd want to emphasize in the (11) of the forest,” said professor John Battles.
“If you were managing to protect these forests, you would leave these trees.”
One of the most carbon-hungry types of trees (12) in the study was the Brazil nut tree, which grows (13) that can easily go beyond a height of 100 feet. (14) total growth and productivity they ranked fourth overall, and they were found to (15) 1.3 percent of the forest's carbon.
“Given the huge biological diversity of tropical forests, (16) cycling would be more equally distributed among plant species,” Rosie Fisher said. “This (17) overturns (推翻)the originally imagined pattern.”
Fisher said she would be “ (18) to suggest the most obvious idea that we could store lots of carbon by planting these very large species”. Because so little is
known about how (19) they are to the types of droughts and fires that are (20) to become more common in the future, nor whether they would thrive (茁壮成长) in managed forests.
