Most teenagers in the United States spend their time trying to make time for school,family and friends.But some choose bigger goals. At age 15,Winter Vinecki has already had more successes than most people have in their lifetime."I recently completed a marathon on all seven continents and became the youngest person in the world to do so.And I was really doing this for my dad." Doctors discovered that Winter's father had a rare and deadly form of prostate cancer when she was nine years old.Then he died 10 months later."When he was first diagnosed with prostate cancer I immediately knew I had to do something to help him.That's when I formed Team Winter for prostate cancer research and awareness." Through Team Winter and social media,Winter Vinecki has raised almost 500,000 dollars.She has taken prostate cancer education worldwide through foot races called marathons,on seven continents.In the United States she travels continually to talk about prostate cancer and urge others to act. Winter Vinecki attended a conference recently in Los Angeles,California and spoke at the conference as one of several teenagers who spoke about young people who were living extraordinary lives. "So prostate cancer is much more common but men don't want to talk about it.So that is why a ten-year-old girl had to go out there and start talking about it for them." Another speaker was Jack Andraka who invented a sensor which is not as expensive as traditional equipment that can't be afforded by most common people.It can identify cancers of the pancreas and lungs.He was 15 at the time. Jack is now 17 and seeking patents for his latest inventions.He has developed low-cost water quality equipment which can help identify and remove heavy metals and poisonous chemicals from water. "I hope to see them used in the developing nations such as Bangladesh and parts of China and India,especially as well as in parts of Africa,where these heavy metal and pesticides and other kinds of waste are a major problem." Winter Vinecki took part in marathons mainly to _ . A) try to realize her father's last wish B) receive education about prostate cancer C) spread knowledge of prostate cancer D) raise money for patients with cancer

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires--not that you cannot satisfy your tastes but that you don't have enough tastes. Real riches consist of well-developed and hearty capacities to enjoy life. Most people are already swamped with things. They eat, wear, go and talk too much. _ Your house of life ought to be a mansion , a royal palace. Every new taste, every additional interest, every fresh enthusiasm adds a room. Here are several rooms your house of life should have. Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry. Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library. Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills. Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit. Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding. The author intends to tell us that _ . A) true happiness lies in achieving wealth by fair means B) big houses are people's most valued possessions C) big houses can in a sense bring richness of life D) true happiness comes from spiritual riches

Ques: Scientists from the Max Plank Institute for Biological Cybernetics in Tubingen, Germany, have presented the first experimental evidence that people do end up walking in circles if lost in unfamiliar areas.The study, published in the journal Current Biology, examined the tracks of people who walked for several hours in the Sahara desert in Tunisia and in the Bienwald forest in Germany.Researchers Jan Souman and Marc Ernst said the scientists used the global positioning system (GPS) to record these paths.The results showed that the walkers were only able to keep a straight line when the sun or moon was visible.As soon as the sun disappeared behind some clouds, people started to walk in circles without even noticing it. Souman said one explanation offered in the past for people walking in circles was that most people have one leg longer or stronger than the other, which would produce a systematic bias in one direction.To test .the researchers asked people to walk straight while blindfolded which removed the effects of vision.They found that these circles were rarely in a systematic direction, with the same person sometimes switching to the left and sometimes to the right. "Most of the participants in the study walked in circles, sometimes in extremely small ones.Walking in circles is therefore not caused by differences in leg length or strength, but more likely the result of increasing uncertainty about where straight ahead is," said Souman, "Small random errors in the various sensory signals that provide information about walking direction add up over time, making what a person perceives to be straight ahead drift away from the true straight ahead direction." Why are the subjects required to be blindfolded? A) To encourage them to walk straight. B) To stop them from seeing each other. C) To dismiss the effects of vision. D) To keep the test a top secret.

Ques:Environmental health is defined as the control of the factors in the environment that may have harmful effects on people's physical, mental, or social well-being . Because natural disasters expose people to danger by bringing up or threatening their immediate environment, effective management of environmental health after a natural disaster is of great importance. The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution of safe and accessible water, and the protection and distribution of safe food products and so on. To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster's specific effects as quickly as possible. This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The recommended environmental health measures have been listed in the order of priority in which they should be taken during an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure. In order to effectively cope with the emergency, the most important is that _ . A) we should have enough shelters and tools B) everyone should be familiar with the situation C) we should be well prepared for it in advance D) we can deal with it just as we did before

Ans:
C
