Sarah came running in saying, "Look what l found. " Over the top of the paper I was reading I saw a long object that made me jump. It was a piece of snakeskin that had been shed （脱皮) by one of our garden snakes.
'Isn't it beautiful?" said my wide-eyed 7~year-old daughter. I stared at the organic wrapper and thought to myself that it really was not that beautiful, but I did not want to disappoint Sarah. Everything children see for the first time is elementary to their sense of beauty and creativity. They see only merit (忧点) and excellence in the world.
"Why does it do this?" Sarah asked. I like to teach my children that there is something else going on besides what they see in front of them. "Snakes shed their skin because they need to renew themselves," I explained.
"Why do they need to renew themselves?" Sarah asked. "We often need to shed our skins, those coatings that we cover ourselves with," I said to my now absorbed daughter. "We outgrow some things and find other stuff unnecessary. This snake no longer needs this skin. It is probably too old, and the snake probably doesn't think it looks as smart in the skin as it once did. Like buying a new suit. "
Of course, I'm sure this explanation won't suit naturalists. But Sarah got the point. As we talked, I knew that she began to understand that renewal is part of progress; that we need to take a good look at ourselves, and rooms and schoolwork and creativity, and she began to see what we need to keep and what need to cast off. I was careful to point out that this is a natural process, not one to be forced.
"Snakes don't peel off their skin when they feel like it," I explained. "lt happens as part of their growth. "
"I see, Dad. " said Sarah. She then jumped off my lap, grabbed the snakeskin, and ran off.
I hoped she would remember this. Often, in order to find our real selves underneath the layers of community and culture we are cloaked (掩饰) in year after year, we need to start examining these layers. We need to gently peel some away, as we recognize them to be worthless, unnecessary, or flawed (有缺陷的); or at best, remember the things we discard（丢掉）to teach us how we can improve.
1.When Sarah asked the author whether the snakeskin was beautiful,___________

Blood donation is a wonderful thing done by us. To begin with, extensive studies show that blood plays a vital role in medical operation. In donating our blood we are actually saving the precious lives of the sick. Next, being a healthy person, losing 200ml of blood is only a small sacrifice and helps to improve our metabolism(新陈代谢). Finally, donating blood helps us in forming good character and developing our sense of social responsibility. Blood donation isn't a complicated issue, but we need to keep a few instructions in mind.
First, don't go for blood donation with an empty stomach. We can eat anything and after having a right diet we'll feel strong and comfortable to donate blood. For the required hemoglobin (血色素) in the body, we can drink lots of fruit juice. For a good blood flow in the body, let's drink at least 6-7 glasses of water daily. Completely avoid taking alcohol or caffeine a day before and after donating our blood. We shouldn't smoke half an hour before making blood donation.
When we’re going for blood donation, first tell the nurse to check our hemoglobin level. During the injection we need to take a deep breath and try to calm ourselves down . During blood donation, keep ourselves cool and calm.
Blood donation is a very fast process, but we need to take care of ourselves after blood donation. For example, take a rest for 15 minutes after the donation. Eat something and drink juice leaving the blood donation centre. Make sure not to skip meals after blood donation .Smoking should be avoided up to one hour after blood donation.
At last be proud of ourselves that we've done a great task in making an attempt of saving someone's life. Blood donation is a social responsibility for every citizen, especially for us, young students. We should do it voluntarily not because it does us no harm but because it is a noble thing to do and it helps others a great deal

Forty years ago, Rachel Carson died and the Pittsburgh area lost perhaps its most influential citizen．A native of a Pennsylvania College for Women graduate, Carson published “Silent Spring” in 1962, a work that launched the modern environmental movement and led to the creation of the Environmental Protection Agency （EPA） as well as the passage of our major environmental laws．
However, there has been a puzzling and troubling trend in recent years: an attack on her theory by conservatives and the agrochemical （农用化学品） industry．For example, Rush Limbaugh gave the following quiz: “Who caused more deaths: Adolf Hitler or RachelCarson?” Limbaugh's answer was Carson, due to the approximately 100 million deaths from malaria （疟疾） since 1972, the year in which the pesticide （杀虫剂）DDT was banned for use in the United States in part as a result of “Silent Spring．”
Therefore, on this 40th anniversary of Carson's death, we need to take a scientific look at the myths that remain about pesticides．
Myth 1: Pesticide usage has declined since 1962．In fact, pesticide usage has more than doubled since 1962, and the global pesticide industry currently uses over 2．5 million tons of pesticides each year．Even DDT is still used abroad．
Myth 2: Pesticides are safe．In fact, as Carson warned us, these poisonous chemicals are unsafe since they are designed to kill biological organisms, but are often not specific in their targets．Pesticide exposure can cause skin irritation, headache, cancer and even death．According to the WHO, over 25 million people a year in developing countries suffer severe acute pesticide poisonings with over 20,000 deaths．
Of the 80,000 pesticides and other chemicals in use today, 10 percent are recognized as carcinogens （致癌物质）．According to recent studies, brain cancer rates are five times higher in homes with “no-pest” strips and six times higher in homes where pets wear flea collars （杀蚤颈圈）．Our homes have pesticide concentrations 10 to 100 times higher than outdoors．
So, if Carson were with us today, still battling the agrochemical industry that spent millions of dollars, what would she be advocating? I feel confident that she would be a strong supporter of a new principle of chemical assessment．
Simply put, this principle requires producers of pesticides to prove that they are safe and necessary before they are put on the market．Our current system puts the burden of proof on government and scientists to prove that a pesticide is dangerous and poses an “unacceptable risk” before it can be pulled from the market．
1．Limbaugh attacked Carson because he thought that _____．
A．“Silent Spring” had caused in part the 100 million deaths from malaria
B．she was supporting the production of poisonous pesticides
C．“Silent Spring” was originated from Hitler’s writings
D．she had not cared for the 100 million deaths from malaria
2．Which of the following is the content of Myth 1?
A．The production of pesticides has doubled during the past 40 years．
B．2．5 million tons of pesticides have been produced since 1962．
C．The usage of pesticides has been dropping since 1962．
D．Pesticides have become less poisonous since 1962．
3．The author mentions “flea collars” in the sixth paragraph to indicate _____．
A．pesticides contribute to the development of cancer
B．the close connection between them and dog cancer rates
C．the medical effect of flea collars on dogs
D．flea collars contribute to high pesticide concentrations indoors
4．What is the suggested new practice of chemical assessment?
A．Government should prove a pesticide is unsafe．
B．Scientists should be responsible for writing assessment reports．
C．Producers of pesticides should provide proof of their safety．
D．A special committee should be set up for chemical assessment．
