Linus Pauling，the only person who has won two undivided Nobel Prizes，was born in Portland，Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962，long after he had received his Bachelor’s degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it.
He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子) led him from physical chemistry to biological chemistry，especially of the human body. He began with proteins and their main parts，the amino acids(氨基酸)，which are called the“building blocks of life”．In 1950，he constructed the first satisfactory model of a protein molecule，a discovery very important to the understanding of the living cell.
During World WarⅡ，Pauling was a member of the Research Board for National Security，for which he was awarded the Presidential Medal of Merit in 1948. However，the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules，he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.
From then on，Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts，The Nuclear­Test­Ban Treaty，declaring all nuclear tests to be illegal except underground ones，came into effect on October 10,1963，the same day Linus Pauling was awarded the Nobel Peace.
【小题1】From the first Paragraph，we learn that Linus Pauling________.

The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.
Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.
The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.
Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.

In 1922 he went to Chicago.There,the tale of Louis Armstrong begins.From then until the end of his life,Armstrong was celebrated and loved wherever he went.Armstrong had no equal when it came to playing the American popular song.
His cornet playing had a deep humanity(仁爱) and warmth that caused many listeners to say,“Listening to Pops just makes you feel good all over.”He was the father of the jazz style(风格) and also one of the best-known and most-admired people in the world.His death,on July 6,1971,was headline news around the world.
【小题1】Armstrong was called Pops because he______.

For eighty four days old Santiago had not caught a single fish. At first a young boy, Manolin, had shared his bad fortune, but after the fortieth luckless day the boy’s father told his son to go in another boat. From that time on, Santiago worked alone. The boy loved the old fisherman and  always helped him with money and food. Usually, they would talk about the fish they had taken in luckier times or about American baseball after supper, while at night, alone in his cottage, Santiago dreamed of lions on the beaches of Africa, where he had gone years before. He no longer dreamed of his dead wife.
On the eighty-fifth day, Santiago set off to fish before dawn. Two of his baits(饵) were fresh tunas(金枪鱼) the boy had given him, as well as sardines(沙丁鱼) to cover his hooks. Then he set his lines which went straight down into deep dark water.
As the sun rose he saw other boats in toward shore. A bird showed him where dolphin were chasing some flying fish. This time Santiago saw tuna jumping in the sunlight. A small one took the hook on his line. Pulling the fish aboard, the old man thought it a good fortune.
Toward noon a marlin, a common fish in the sea, started eating the bait which was one hundred meters down. Gently the old man played the fish, a big one, as he knew from the weight on the line. At last he struck to settle the hook. The fish did not come out of the surface. Instead, it began to pull the boat to the northwest. The old man followed it. Although he was alone and no longer strong, he had his skill and knew many tricks. He waited patiently for the fish to be tired .
It was cold after the sunset. When something took one of his remaining baits, he cut the line with his knife. Once the marlin leaned suddenly, pulling Santiago forward on his face and cutting his cheek. By dawn his left hand was cramped(抽筋的). The fish had headed northward; there was no land in sight. Hungry, he cut pieces from the tuna and chewed them slowly.
That morning the fish jumped. Seeing it, Santiago knew he had hooked the biggest marlin he had ever seen. Then the fish went down and turned toward the east. Santiago drank a little water from the bottle during the hot afternoon.
Close to nightfall a dolphin took the small hook he had rebaited. He lifted it aboard, careful. After he had rested, he cut meat from the dolphin and kept also the two flying fish he found in its stomach. That night he slept. He awoke to feel the line running through his fingers as the fish jumped. Feeding line slowly, he tried to tire the marlin. After the fish slowed its run, he washed his cut hands in sea water and ate one of the flying fish. At sunrise the marlin began to circle. Faint, he worked to bring the big fish nearer with each turn. Almost exhausted, he finally drew his big fish alongside and drove in the harpoon(鱼叉). The fish was two feet longer than the boat. No fish like it had ever been seen in Havana harbor.
An hour later, he sighted the first shark, a fierce Mako, and it came in fast to chase after the dead marlin. The old man struck the shark with his harpoon. The Mako rolled and sank, carrying the harpoon with it and leaving the marlin bloody. He knew the smell would spread. Watching, he saw two sharks closing in. He struck at one with his knife and watched it sliding down into deep water. The other he killed while it tore at the flesh of the marlin. When the third appeared, he thrust(刺) it with the knife. The other sharks came at sunset. At first he tried to beat them with the tiller(舵柄) from the boat, but his hands were bleeding and there were too many in the sea. In the darkness, as he steered toward the harbor of Havana, he heard them hitting the boat again and again. But the old man thought only of his steering and his great tiredness. He had gone out too far and the sharks had beaten him. He knew they would leave him nothing but the stripped skeleton of the big marlin.
All lights were out when he sailed into the little harbor and beached his boat. He could just make out the white backbone and the upstanding tail of the fish. Once he fell under their weight and lay patiently until he could gather his strength to go on. In his cottage he fell on his bed and went to sleep.
【小题1】The above story is adapted from __________.

Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu--- but which one? Although both colds and flu are caused by viruses, they are very different illnesses.
Colds, which usually last about a week, affect the nose most. They commonly cause a runny nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is much more serious illness and is caused by different group of viruses. People with flu usually get all the symptoms described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the typical symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly, who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection before the start of winter when flu is most common. This injection is inexpensive and definitely worth it.
If you have a cold or flu, you must always deal with used tissues carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze！You don’t want to see the small drop of liquids blown out of your nose and mouth when you sneeze, do you? Disgusting, eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!
