Question: Article: Animals can be extremely protective of their young. But when hard times call, animal fathers can be really a danger to their own kids. Daddy Lion A combination of laziness, pride, cruelty and anger makes the lion one of the most fearsome and worst dads of the animal kingdom. When not walking proudly across the jungle, the father lion just lazes around under the sun, or waits for one of its lioness partners to bring back food. Once the lioness gets home the food, the lion eats up most of it, and leaves little or nothing at all for the kids. The father doesn't even train the kids for hunting and surviving, it is the lioness who teaches them how to _ themselves. The Polar Father Cute, pure and soft. Protective of young ones and family? Sure. But what makes the polar bears one of the worst dads of the animal kingdom? They don't take care of the young ones, they won't take up the responsibility of feeding them, they won't take care of them like a father should. They just leave that to the mother bear. The Assassin Bug Size matters, you say? This little bug would eat its own eggs to stay strong and fulfill its hunger needs. The male assassin bug is actually responsible for guarding the eggs. The female assassin bug lays eggs in large numbers. The male bug eats the weaker eggs. Daddy Bass Usually, water calms you down. Not so much for this underwater species. The male bass is known to eat up eggs from its own spawn. It guards the spawn(,) laid by its female partner. However, when hungry and unable to hunt for food, the father won't think twice before eating up the eggs. And do you think your father was strict and hard? After reading this article, I'm sure you think your dad is the best in the whole wide world for not eating you up!

Question: 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

Answer: The chief purpose of developing GM foods is to _ .

Question: Article: I got up and dressed, stuck my violin under my jacket, and went out into the street. I wandered about for an hour, looking for a likely place, feeling as if I were about to commit a crime. Then I stopped at last under a bridge near the station and decided to _ . I felt tense and shaking. I drew my violin from under my coat like a gun. It was here, in Southampton, with trains passing overhead, that I was about to prove myself. The first notes I played were loud and raw, and then they settled down and began to run more smoothly and to stay more or less in tune. To my surprise I was neither arrested nor told to shut up. Indeed, nobody took any notice at all. I walked the streets of Southampton for several days, gradually knowing how to try and get money by being a street artist. It was not a good thing, for instance, to let the hat fill up with money -- the sight could discourage the people; nor was it wise to empty it completely, which could also confuse them, giving them no hint as to where to drop his money. Placing a couple of pennies in the hat to start the thing going soon became a good idea. Before I played another tune, I took off the big money, but always left two pennies behind. Old ladies were most generous, and so were women with children, shop girls, and typists. As for the men: Heavy drinkers were always generous too and so were big young with muscles. But never a man with a hat, briefcase or dog; respectable types were the meanest of all, except retired army officers, who would bark "Why aren't you working, young man?" and then threw much money into the hat to hide their confusion.

Answer:
When the writer began to play the violin, he thought that _ .
