Ques:Nobel, who was born in Stockholm, is a great scientist famous for his dangerous experiments. Nobel studied in the USA and then Russia between 1850 and 1859. After his return, he started researching into bombs. As is known, bomb is dangerous to life, but Nobel was working under that condition. Once a big explosion in his lab completely destroyed the lab and caused some deaths. After that he had to experiment on a boat in a lake. He received criticism and satire , but he proceeded with the work rather than losing heart. From 1860s to 1880s, Nobel made many achievements and his inventions were first used in building roads and digging tunnels. Most of the bombs were safer and more possible to be controlled. Even at the end of the 20th century, we still used his methods. Nobel had many patents in Britain and other European countries. He was quick to see industrial openings  for his scientific inventions and built up over 80 companies in 20 different countries. Indeed his greatness lay in his outstanding ability to combine the qualities of an original scientist with those of a forwardlooking industrialist. But Nobel's main concern was never with making money or even with making scientific discoveries. Seldom happy, he was always searching for a meaning to life, and from his youth, he had taken a serious interest in literature and philosophy. His greatest wish, however, was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause. To follow his will, a fund was set up to encourage people to make great progress in physics, chemistry, physiology , medicine, literature and peace. That's the Nobel Prize which means great honor to a scientist. In fact, his inventions were first used in   _  . A) a war to kill and injure his fellow men B) building roads C) digging tunnels D) both B and C

Ques:No quick change I would be the first to say that I am not materialistic. My friends regard me as a goody-goody  . My parents say I am conservative   and modest when it comes to clothes. I don't wear bikinis, and none of my skirts or shorts end above my knees. That is my choice. So why, why did I decide to buy that skirt? My family and I were in Target, and there it was, waiting - a skirt specifically designed not to cover anything. It was light brown and looked like something one of those anime   schoolgirls would wear. I checked my purse. The skirt cost $10. I had the money. I could buy it. I imagined walking into school and my pals' jaws   dropping. Guys would ask me out, and I would be happy. I could buy it - no, I should buy it. I showed my mother. She was surprised but said it was my decision. My sister looked on jealously. I went into the dressing room to try it on. I was so sure that this skirt would change me, somehow make me not what I am but what I wished to be. I slid my jeans off and put it on. Now for the decisive moment. I looked in the mirror. There I was - a girl in a Superman T-shirt and sneakers who didn't know how to make friends with others. Of course, the skirt had not changed me. It fit me well; that wasn't the problem. It might make me look good in the eyes of today's world. But it simply was not me. I am not a girl who wears cool clothes to fit in. My glasses fogged up as I started to cry. I took the thing off and went back into the comfort and safety of modesty. My mom knocked on the door. "Emily, are you okay?" I wiped away my tears. "I'm fine." I looked in the mirror again and saw a blond skinny girl with thick glasses and a ponytail  . I saw myself. How did the author think her friends would react to her new skirt? A) They would be jealous when they saw how beautiful she looked. B) They would think of her as a goody-goody. C) They would start to copy her new style. D) They would be amazed to see the big change in her.

Ques:The prefix = st1 /USgovernment has announced plans to list polar bears as a threatened species because of concerns that the ice where they live is melting. But as the BBC's Owen Clegg reports, theUSplans are also important for other reasons. It's estimated that there are no more than twenty-five thousand polar bears living in the wild, and this number could go down by a large amount as the floating ice upon which the bears survive melt away. Now, without admitting the cause of this melt, the US Fish and Wildlife Services are reviewing the bear's living conditions.    That action is being taken at all, and marks an important change for the Bush administration; for the first time, it may be forced to acknowledge a link between global warming and its effect on a species. Such a conclusion by an unwilling Bush administration could force far wider changes inWashington's policy towards the environment.    This review only came about after a union of environmental groups brought a legal case against the government to take action. Environmentalists, like David Doniger, believe that by calling on the protections of the Endangered Species Act, theUSgovernment may finally be forced to cut back on its sending out greenhouse gases:    "It is a very important thing today to have the Bush administration notice that global warming is threatening the existence of the polar bear. Now, it's up to the administration to do something to stop the global warming that's threatening the polar bear." ( David Doniger)    The United States is the world's largest emitter of greenhouse gases which are blamed for trapping heat from the sun and changing the earth's climate. Since taking office in 2001, President Bush has refused to make the link with global warming, but the bad, serious situation of the polar bear may force that position to change. What is the direct reason for the polar bear to become endangered? A) It is that the floating ice upon which they survive melts away. B) It is that more greenhouse gases have been sent out. C) It is because of the global warming. D) It is because of no protection of their living conditions.
