Just about every week now, we read a newspaper headline about the genetic basis for breast cancer, intelligence, orobesity. Such news stories may lead us to believe our lives are being _ by genetic discoveries. We may be close to changing and getting rid of mental illness, for example and identify the causes of crime,personality, and other basichuman weaknesses. But these hopes, it turns out, are based on faulty assumptions about genes and behavior. In many cases, people are motivated to accept research claims by the hope of finding solutions for frightening problems, like breast cancer. Accepting genetic causes for their characteristics can relieve guilt about behavior they want to change but can't. Efforts made to fight against them, at growing expense, have made little or no visible progress. The public wants to hear that science can help. Meanwhile, genetic claims are being made for many ordinary and abnormal behaviors, from addictiontoshynessand even to political views anddivorce. If who we are is determined from pregnancy, then our efforts to change or to influence our children may be useless. There may also be no basis for insisting that people behave themselves and obey laws. Thus, the revolution in thinking about genes has great consequences for how we view ourselves as human beings. Most claims linking emotional disorders and behaviors to genes are statistical in nature. The research finds are insufficient for deciding that alcoholism or manic-depression is inherited. In the late 1980s, genes for manic-depression were identified by teamsof geneticists. The claims have now been definitively proved wrong. Genetic data on the major mental illnesses make it clear that they can't be reduced to purely genetic causes. According to Myrna Weissman, Ph.D., Americans born before 1905 had a 1 percent rate of depression by age 75. Among Americans born a half century later, 6 percent become depressed by age 24! Similarly, while the average age at which manic-depression first appears was 32 in the mid 1960s,... Which do you think is the best title of the passage? A) My Genes Made Me Do It B) Nature and Education C) Here's the Myth of Genes D) Genetic Discoveries

A month went by in this manner, but a month was all I could bear. The memory of Marguerite accompanied me wherever I went. I had loved that woman -- still loved her -- too much for her suddenly to mean nothing to me. Whatever feelings I might have for her now, I had to see her again. At once. ... I knew Marguerite. Meeting me so unexpectedly must have thrown her into a state of great confusion. Probably, she had heard of my departure which had set her mind at rest as to the consequences of our sudden parting. But, seeing me back and coming face to face with me, weak as I was, she had sensed that my return had a purpose, and must have wondered what was going to happen. If, when I saw her again, Marguerite had been unhappy; if, in taking my revenge , there had also been some way of helping her then I might well have forgiven her, and would certainly never have dreamed of doing her any harm. But when I saw her again, she was happy, at least on the surface. Another man had ensured her the wealthy life in which I had been unable to keep her. She brought shame both to my pride and my love; she was going to have to pay for what I had suffered. I could not remain cold to what she did now. It followed that the thing that would hurt her most would be exactly for me to show coldness. Coldness, therefore, was the feeling which I now needed to pretend, not only in her presence but in the eyes of others. I tried to put a smile on my face, and I went to call on Prudence with whom Marguerite was staying. ... Prudence saw me to the door, and I returned to my apartment with tears of anger in my eyes and thirst for revenge in my heart and thought only of finding a way to make the poor creature suffer. What kind of feelings did the hero most probably have? A) Coldness and love. B) Coldness and hate. C) Love and hate. D) Hate and sadness.

Q: As the population grows and temperatures rise, it will become more difficult to grow enough food for everyone. So, scientists are exploring the planet for plants that do not need as much water as today's crops. The Mojave Desert in the US state of California is home to some of these plants. Scientist Heather Rose Kates of the University of Florida is in that desert. She is searching along roads for a plant called coyote melon which is a kind of squash .Coyote melon may not taste good, but it can be grown in places that have little rainfall. The desert where it grows gets just 15 to 20 centimeters of rain per year, or less. Other kinds of squash need at least two and a half centimeters per week to grow. Scientists are considering combining wild coyote melon with regular squash to see if they can make a tasty vegetable that doesn't need as much water to grow. That could be useful on a planet growing warmer and more crowded every day. Andy Jarvis works at the International Center for Tropical Agriculture. He says farmers will need to produce 50 to 70 percent more food by 2050 to feed the world. So, he says, researchers are studying the wild versions of farm-grown crops. But he says there is a problem. He says many wild versions of farmed plants are disappearing. He says they are threatened and scientists have not collected their seeds for future use. Scientist Kates is part of an international effort to gather these plants and save their seeds while it is still possible. Workers are collecting wild potatoes in Argentina and wild peppers in Para-guav. The plants and seeds will be sent for storage to the Global Seed Vault in Norwav and at Kew gardens in Britain. Ms Kates spends most of her time in a laboratory. She says gathering plants has helped her understand more about them. Why do scientists study coyote melon? A) It tastes good. B) It is easy to cook. C) It only needs little water to grow. D) It is welcomed by many American people.

*Question*
An international panel of experts will re-examine all data gathered in the nearly two-month hunt for the missing Malaysia jet to ensure search crews have been looking in the right place, officials said Monday. Senior officials from Malaysia, Australia and China met in the Australian capital to _ the details of the next steps in the search for Malaysia Airlines Flight 370, which will center around an expanded patch of seafloor in a remote area of the Indian Ocean off Western Australia.The area became the focus of the hunt after a team of analysts calculated the plane's most likely flight path based on satellite and radar data.Starting Wednesday, that data will be re-analyzed and combined with all information gathered thus far in the search, which hasn't turned up a single piece of debris despite crews searching more than 4.6 million square kilometers of ocean. "We've got to this stage of the process where it's very sensible to go back and have a look at all of the data that has been gathered, all of the analysis that has been done and make sure there's no flaws in it, the assumptions are right, the analysis is right and conclusions are right," Angus Houston, head of the search operation, told reporters in Canberra. Investigators have been confused by a lack of hard data since the plane vanished on March 8 during a flight from Kuala Lumpur to Beijing.A weeks' long search for surface debris was called off last week after officials determined any debris that may have been floating has likely sunk. "Unfortunately, all of that effort has found nothing," Australian Transport Minister Warren Truss said."We've been confident on the basis of the information provided that the search area was the right one, but in practice, that confidence has not been converted into discovering any trace of the aircraft." Houston has warned the underwater search is likely to drag on for up to a year. The main purpose of the passage is to inform us of _ . A) the likeliest fly path based on satellite and radar data B) the wrong area for MH370 searching C) the further information about the Missing Malaysia Airlines D) the final result of the searching
