　　My aunt Edith was a widow of 50, working as a secretary, when doctors discovered what was then thought to be a very serious heart ailment.

　　Aunt Edith doesn't accept defeat 1 . She began studying medical reports 2 and found an article in a magazine about a (an) 3 heart surgeon（外科医生）, Dr. Michael DeBakey, of Houston, Texas. He 4 the life of someone with the same ailment. The article said Dr. DeBakey's fees（费用）were very high; Aunt Edith 5 not possibly pay them. But could he tell her of someone 6 fee she could pay?

　　So Aunt Edith 7 to him. She simply listed her 8 for wanting live: her three children, who would be on their own in three or four 9 years, her little-girl dream of 10 and seeing the world. There wasn't a word of 11 --only warmth and humor and the joy of living. She mailed the letter, not really 12 an answer.

　　A few days later, my doorbell rang. Aunt Edith didn't 13 to come in; she stood in the hall and read aloud: “Your beautiful letter 14 me very deeply. 15 you can come to Houston, there will be no charge （收费）for either the hospital or the 16 . Signed--Michael DeBakey.”

　　That was seven years ago. 17 then, Aunt Edith has been around the world. Her three children are 18 married. For her age, she is one of the youngest, most 19 people I know--all because of an open heart surgeon 20 knew how to honor his job, and how to open his own heart.

As a result of pollution , Lake Erie , on the borders of the USA and Canada, is now without any living things.　　
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organism(生物体 ) to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.　　
Where do the substances which pollute the water come form? There are two main sources sewage (污水) and industrial waste. As more detergent (洗涤剂 ) is used in the home, so more of it is finally put into our rivers. lakes and seas. Detergents harm water birds dissolving the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous things in it, such as copper and lead(铅 ).　　
So , if we want or stop this pollution , the answer is simple: sewage and industrial waste must be made clean before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

For most of the day construction worker Sidney Smith and his brother – in – law Joseph Chambers had been   21   along the banks of Lake Waco with little   22  .

Smith drove his pickup（小货车）a couple of miles along the　26　road to get to the other side of the lake. This road, in the truest sense, was a path wagging in the heavy 　27　area.

“A guy could get lost and nobody would ever find him,” said Chambers.

Smith smiled, “We’re 　31　there.” He said. A few seconds later, the smile was 　32　　from his face.

“What the hell is that?”

　　He braked to a stop. Less than twenty feet away was what appeared to be a  33  .

　　For several minutes the two men sat in the pickup 　34　to decide whether they had happened to 　35　someone’s bad practical joke or something far more serious. Smith with his brother-in-law got out of the pickup and 　36　walked towards that thing some distance before them.

It was a young man who was already dead. They had got to tell 　37　. Back into the pickup, Smith backed the pickup down the road 　38　he could turn around, then 　39　back. With the dead young man still on his mind, Smith felt as if he was going to be sick. God, how he　40　　they had given up fishing and gone home early.

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
