Kieron Williamson, a seven-year-old British boy, is being recognized as an art genius after selling 16 paintings for 18, 000 pounds in just 14 minutes. This boy has artistic skills that would be the envy of any serious painter and drawn comparisons(,) to Pablo Picasso, a child prodigy who became one of the most recognized artists of the 20th century. It all began on a family holiday to Cornwall on the southwest English coast when Kieron was five. Inspired by the beautiful view, he asked his parents for his first sketch-pad . From that moment on, he became deeply interested. While supportive, Kieron's parents are careful not to push their son. He only paints when and what he wants. He has a waiting list of hundreds and requests for his works have been flooding in. His father said a sale of Kieron's works held in November even drew a buyer from Japan. "We had people driving down that night, there were people on the door waiting to come in the morning who had been standing outside, the phones were going mad as soon as the door opened at nine o'clock and within 14 minutes all the 16 pictures had gone, " he said. All this talent, money and high praise could so easily go to a young boy's head, but Kieron said his friends keep him grounded. "Some of them want to be as good as me and some of them think. . . Umn, 'you are not too special'." he said. Kieron's favourite painter is British artist Edward Seago and he has spent some of his earnings buying a work by his hero. The rest is being invested by his parents until he reaches 25. Kieron's parents and his younger sister Billi-Jo don't see him as anything but a average seven-year-old boy who likes to tear around the house and who's mad about football. But for now, with so much still to learn, there's only one thing he wants to be when he grows up. He said, "I think I'll be an artist." In Kieron Williamson's friends' opinion, he _ . A) is very famous and too proud B) works very hard at school C) should receive praise from others D) is as average as other children

"Hypotheses ," said Medawarin 1964, "are imaginative and inspirational in character"; they are "adventures of the mind". He was arguing in favour of the position taken by Karl Popper that the nature of scientific method is hypothetico-deductive and not, as is generally believed, inductive. The myth of scientific method is that it is inductive: that the formulation of scientific theory starts with the basic, raw evidence of the senses -- simple, fair, unprejudiced observation. Out of these sensory data -- commonly referred to as "facts" -- generalisations will form. The myth is that from a disorderly collection of factual information an orderly, relevant theory will somehow come out. However, the starting point of induction is an impossible one. There is no such thing as an unprejudiced observation. Every act of observation we make is a function of what we have seen or otherwise experienced in the past. All scientific work of an experimental or exploratory nature starts with some expectation about the outcome. This expectation is a hypothesis. Hypotheses provide the motivation for the inquiry and influence the method. It is in the light of an expectation that some observations are held to be relevant and some irrelevant, that one method is chosen and others abandoned, that some experiments are conducted and others are not. Hypotheses arise by guesswork, or by inspiration, but having been started they can and must be tested thoroughly, using the appropriate method. If the predictions you make as a result of deducing certain consequences from your hypothesis are not shown to be correct then you abandon or adjust your hypothesis. If the predictions turn out to be correct then your hypothesis has been supported and may be kept until such time as some further test shows it not to be correct. Once you have arrived at your hypothesis, which is a product of your imagination, you then move on to a strictly logical and thorough process, based upon deductive argument -- therefore the term "hypothetico-deductive". So... According to the author, a good scientific research is a process _ . A) starting from details and ending in generalisations B) where observations play more role than expectations do C) where hypotheses are gradually tested before finally approved D) which cannot be started before enough evidences are collected

Q: Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment. Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school inprefix = st1 /New Jerseyhad to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area. Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health. Some governments have realized how serous the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce. Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods. The writer of the text thinks that _ . A) governments should have forbidden the production of waste chemicals B) mixed waste chemicals can always be stored without endangering people C) industries must not produce waste chemicals which harm people so much D) everyone can do something to help solve the problem of waste chemicals

As we know, Human beings each have unique brains. The brain is of the greatest importance to the body. It is the boss of the body.Your eyes,ears,nose,and skin tell your brain what is going on around you.Other parts of your body tell your brain what is going on inside of you.Your brain takes in the signals.It tells your body what to do with them.When you touch fire,your skin tells your brain that your finger is too hot.Your brain tells you to move your finger.All these happen very fast.Your brain also controls your breathing,blinking,and heartbeat.It controls your feelings and thoughts too. Humans have the most developed brain of all animals.Yet it is not the largest brain.The human brain weighs three pounds.The brain of an elephant weighs 11 pounds.So the largest brain is not always the best brain.In people,a larger brain does not mean a clever person. What is the main idea of this passage? A) The human brain works very fast. B) The largest brain is not always the best brain. C) The brain controls the body. D) The best brain is the largest brain.
