Americans who volunteer for the Peace Corps get a chance to help improve lives in developing countries. They also get a chance to learn more about the world, and about themselves. This week this program is celebrating its 50th anniversary. President John Kennedy established the Peace Corps soon after he took office in 1961. It was the time of the Cold War between the United States and the Soviet Union. The new program gave Americans a chance to answer the call to service that the president made in his inaugural speech. "Ask not what your country can do for you," he said. "Ask what you can do for your country." Kennedy told Peace Corps volunteers that America's image in the countries where they were going would depend largely on them. On August 30th, 1961, the first group of 51 Peace Corps volunteers arrived in Accra, Ghana, to serve as teachers. They had agreed to work for almost no pay. They would spend two years in Ghana helping its people and learning the reality of life in a developing country. Most of the volunteers had just completed college. About half of them taught English or health care. In the 50 years since then, more than 200,000 Americans have served as Peace Corps volunteers. They have worked in 139 countries. The Peace Corps is a government agency that was created to promote world peace and friendship. There are three goals: First, to help the people of interested countries in meeting their need for trained men and women. Second, to help promote a better understanding of Americans on the part of the people served. And, third. to help promote a better understanding of other people on the part of Americans. Today, the Peace Corps has more than 8,000 volunteers and trainees in 77 countries. They work in agriculture, economic development, education, the environment and health care. Some work in programs related to youth development. Sixty percent of current Peace Corps volunteers are women. The average age of a volunteer is 28. But the ages of Peace Corps volunteers range from 18 to 86. Some... According to the text, volunteers and trainees assist in the following aspects EXCEPT   _  . A) industry B) environment C) education D) health care

It came with devastating force,a natural disaster of strange intensity that shocked the world and killed tens of thousands.The waters have now receded,but disease and food and water shortages trouble a number of countries around the Indian Ocean.Millions of survivors face serious problems. The number of survivors in need of food aid after the Indian Ocean disaster has climbed to 5 million people.They stretch from Somalia to Thailand,and the figure could rise further,the United Nations has said. Relief teams hope to reach all of the estimated 700 000 hungry in Sri Lanka within three more days.It could take longer before enough food aid gets to the nearly 1 million people in need in hard-to-reach parts of Indonesia.Another serious problem is the need for purified water. Although aid had poured in from all over the world to the disaster areas,"Logistics is the big problem here--just getting the stuff out to people who need it,"said Ron Libby,emergency management specialist at the USA agency for International Development. Relief efforts are hindered by the difficulty of delivering aid to the more than 1000 islands scattered across hundreds of kilometers of ocean. For those who survived the tsunami's force,disease is now the No.1 problem.Five million people are short of water,food and basic sanitation across the region.World Health Organization(WHO) crisis chief David Navarro said 50 000 more people could die from disease and other causes,as has been the case in previous humanitarian emergencies. WHO said it had already received a handful of reports of malaria  and dengue fever  and hundreds of reports of diarrhea  and infected wounds.It said millions of water purification tablets had been sent to Asia,along with sanitation engineers to rebuild water sanitation infrastructure. Psychologists are warning that mental health problems caused by the tsunami could prove harder to resolve than the physical damage. Some survivors say they are plagued by recurring nightmares about walls of water.Many locals are afraid to... This passage is mainly about   _  that happened around the Indian Oceans. A) the causes of the tsunami B) the result after the tsunami C) the sign of the tsunami D) the warning of the tsunami
(Answer)
B


Ques: What are feelings for? Most nonscientists will find it a strange question. Feelings justify themselves. Emotions give meaning and depth to life. They exist without serving any other purposes. On the other hand, many evolutionary biologists acknowledge some emotions primarily for their survival function. For both animals and humans, fear motivates the avoidance of danger, love is necessary to care for the young, and anger prepares one to hold ground. But the fact that a behavior functions to serve survival need not mean that. Other scientists have regarded the same behavior as conditioning and learned responses. Certainly reflexes  and fixed action patterns can occur without feeling or conscious thought. A baby seagull pecks  at a red spot on the bill  of its parent. The seagull parent feeds its baby when pecked on the bill and the baby gets fed. The interaction need have no emotional content. At the same time, there is no reason why such actions cannot have emotional content. In mammals that have given birth including humans, milk is often released automatically when a new baby cries. This is not under intended control but it is reflex. Yet this does not mean that feeding a new baby is exclusively reflex and expresses no feeling like love. Humans have feelings about their behavior even if it is conditioned or reflexive. Yet since reflexes exist and conditioned behavior is widespread, measurable, and observable, most scientists try to explain animal behavior by using only these concepts. It is simpler. Preferring to explain behavior in ways that fit science's methods most easily, scientists have refused to consider any causes for animal behavior other than reflexive and conditioned ones. Scientific orthodoxy  holds that what cannot be readily measured or tested cannot exist, or is unworthy of serious attention. But emotional explanations for animal behavior need not be impossibly complex or unstable. They are just more difficult for the scientific method to check on in the usual ways, so cleverer and more... The example of the baby seagull pecking the parent's bill is used to support that   _  . A) it is an inborn ability for adults to look after the young B) behaviors can be learned and involve no emotions C) emotions are of great importance for survival D) it takes time for animals to be conditioned
Ans: B


Ques:DNA is a substance that makes up genes. Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity  . Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree's genes tell what shape its leaves will be. A cat's genes tell what color1 its fur will be. Your genes tell what color1 your eyes will be. Your genes tell what color1 your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells.   An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits  , Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes.   In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases--diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by  _ genes through a process called gene therapy. If one's father has blue eyes, while his mother has grey ones,   _  . A) their son will have blue eyes. B) Their son is sure to have grey eyes. C) their son's eyes will share both that of father's and mother's. D) It is probably their son will have either blue eyes or grey ones.
