Article: The world has a fast growing population and people need more land for houses, factories, highways, and so on. The farmland is decreasing with each passing day. How to meet the need of feeding the growing population? One way is to introduce some high-output gene into a crop to enable it to produce more. Biologists over the years have discovered genes which can raise output of the crops, resist pests, improve taste, etc. However, in many western countries there is widespread concern over the safety of"Genetically Modified"(GM) foods, because they think there may be serious problems of environment, health, safety, morality and so on. As a scientist I must admit GM foods involve great risks to humans. In fact in Europe they're called "Frankenstein foods" by many. Frankenstein is a character in a novel. He was a very clever scientist. He created a monster , which eventually killed him. Soybeans can be made into many foods. However, it's hard to _ . Therefore, it's very important we have to make sure the soybean, if genetically modified, is free from any poisonous matter harmful to human beings. For this we need very good testing. We do have some testing on some animals, but no completely satisfactory testing has ever been made so far. They're entirely new, and their problems are entirely unknown. It takes time to develop persuasive tests to know whether they're harmful to us or not. We may not be able to tell what may happen if we take GM foods. Some of them may be resistant to antibiotics . Then many of the medicines we have today will have no effect on people eating GM foods. A more likely case is the GM foods may contain genes some people are allergic to. GM products have already come into our lives but most people even know nothing about it. At least we have to be clear about what we are eating. The China Consumers Association is calling for labeling on GM foods so that consumers will know before they buy them.
Answer: feed the fast growing population
The chief purpose of developing GM foods is to _ .

Article: Hercule Poirot looked over the small gate which gave admission to Pine Crest. It was a modern nicely-built house. It was on a hill top, and the hill top was planted with a few sparse pines. It had a small neat garden and a large elderly man was watering with a big tin. Spence's hair was now grey all over. He had not shrunk much in girth , though. He stopped watering and looked at the visitor at the gate. Hercule Poirot stood there without moving. "God bless my soul," said Spence. "It must be. It can't be but it is. Yes, it must be Hercule Poirot!" "Aha," said Poirot, "you remember me. I'm grateful." Spence abandoned the watering can and came down to the gate. "What brings you down here?" "What has brought me to many places in my time," said Poirot, "and what once a good many years ago brought you to see me. Murder, Spence." "I'm done with murder since I retired," said Spence, "except in the case of weeds. Killing weeds is never easy as you think, something's always wrong. How did you know where to find me?" he asked as he opened the gate and Poirot passed through. "You sent me a Christmas card. It had your new address on it." "Ah yes, so I did. I'm old-fashioned, you know, I like to send round cards at Christmas time to a few old friends. I'm an old man now." "We both are." "Not much grey in your hair," said Spence. "I take care of my hair with a bottle," said Poirot. "There is no need to appear in public with grey hair unless you wish to do so. By the way, why have you come to live in Woodleigh Common?" "As a matter of fact, I came here to join forces with a sister of mine. She lost her husband, her children are married and living abroad. So I moved in here. Pensions don't go far nowadays, but we do comfortably living together."
Answer: Poirot's recent life
From their dialogue, we can learn about _ .

Article: How to deal successfully with a child who shows outstanding musical ability?It's not always clear how best to develop and encourage his gift.Many parents may even fail to recognise and respond to their children's need until frustration explodes into difficult or uncooperative behaviour.And while most schools are equipped to deal with children who are specially able in academic subjects,the musically gifted require special understanding which may not always be available in an ordinary school--especially one where music is regarded as a secondary activity.Such children may well benefit from the education offered by a specialist music school. The five music schools in Britain are a relatively recent introduction.They aim to provide an environment in which gifted children aged between seven and eighteen can develop their skills to the full under the guidance of professional musicians. Children at specialist music schools spend between one third and one half of an average day on musical activities,for example,individual lessons,orchestras,chamber groups,voice training,conducting and theory.They also spend several hours a day practising in properly equipped private rooms,sometimes with a teacher.The rest of their time is taken up with the subjects:English,maths,basic sciences and languages.All five British specialist schools are independent,classes are small by normal school standards,with a high teacher/pupil ratio .Most children attending specialist schools tend to be boarders,leaving home to live,eat and sleep fulltime at school. What are the disadvantages?An obvious problem is the cost;the fees are high(PS12,000PS17,000 a year for boarders).However,each school will make every effort with scholarships and other forms of financial assistance,to help parents of outstandingly gifted children to find the necessary fees.Secondly,not all parents want to send their children to boarding school,especially at a very early age.Almost all the directors of the specialist schools express doubts about the wisdom of admitting children as young as seven into such an intense and disciplined environment.They stress,however,that their main aim is to turn out "rounded and wellbalanced" individuals. There is little doubt that setting musically gifted children apart from an early age can cause stress.Early signs of musical ability may disappear in their teenage years,while natural competitiveness and the pressure to succeed can lead to a deep sense of failure.But all specialist schools do keep a close watch on the progress of individual pupils,and offer help and advice if needed.
