B
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.

　　A. when the first organisms are affected

A few days ago I asked my sons’ governess（女家庭教师）Julia to come into my study. “Be seated, Julia, ”I said, “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”

　　“Forty.”

　　“No, thirty. I made a note of it. I always pay our governess thirty. Well, um, you’ve been here two months, so...”

　　“Two months and five days.”

　　“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... you know you didn’t work with Tom on Sundays, you only took walks. And three holidays... ”Julia was biting her finger nail nervously, her face red, but - not a word.

　　“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven - nineteen. Take nineteen off ... that leaves. hmm.... forty one dollars. Correct？”

　　Julia’s left eye reddened with tears welling up. Her chin trembled; she coughed nervously and blew her nose, but - still not a word.

　　“Around New Year’s Day you broke a teacup and a saucer; take off two dollars. The cup cost more, it was a treasure of the family, but- forget it. When didn’t I take a loss! Then, due to your neglect （疏忽）, Tom climbed a tree and tore his jacket; take away ten. Also due to your carelessness the maid stole Dick’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave ten dollars.”

　　“You didn’t. ”sobbed Julia.

　　“But I made a note of it.”

　　“Well... if you say so.”

　　“Take twenty seven from forty one -that leaves fourteen.”

　　Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!

　　“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, nothing more.”

　　“Really? You see now, and I didn’t know that! Take three from fourteen.. leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is !”

　　I handed her eleven dollars. She took them and pocketed them.

　　“Merci （法语: 谢谢）,”she whispered.

　　I jumped to my feet and started pacing the room. I was overcome with anger. “For what, this - ‘merci’?” I asked.

　　“For the money. ”

　　“But you know I’ve cheated you - robbed you ! I have actually stolen from you ! Why this‘merci’？”

　　“In my other places they didn’t give me anything at all.”

　　“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you... I m going to give you all the eighty dollars! Here they are in the envelope all ready for you... Is it really possible to be so spineless （懦弱）?Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws（爪）—to be such a fool?”

　　Embarrassed, she smiled. And I could read her expression,“It is possible.”

　　I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little“merci”several times and went out. I looked after her and thought,“How easy it is to crush the weak in this world !”

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.

　　[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.

　　[3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.

　　[4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.
