It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness For Killing Wolves In Alaska,the wolf almost disappeared a few years ago,because hunters were killing hundreds of them for sport. However.1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur.So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food.Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life.When the deer can't find enough food,they die. If the wolves continue to kill large numbers of deer,their prey will disappear some day.And the wolves will.too.So we must change the cycle of life in the wilderness to balance the ecology.If we killed more wolves,we would save them and their prey from dying out.We'd also save some farm animals. In another northern state,wolves attack cows and chickens for food.Farmers want the government to send biologists to study the problem.They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population. Against Killing Wolves If you had lived long ago,you would have heard many different stories about the dangerous wolf.According to most stories,hungry wolves often kill people for food.Even today,the stories of the "big bad wolf'"will not disappear. But the fact is wolves are afraid of people.and they seldom travel in areas where there is a human smell.When wolves eat other animals,they usually kill the very young.or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived.And has always been a law of... According to those against killing wolves,when wolves eat other animals, _ . A) they never eat strong and healthy ones B) they always go against the law of nature C) they might help this kind of animals survive in nature D) they disturb the ecological balance in the wilderness

Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day. Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats even if it's hard to explain." The US research team studied how well students remembered connections between words and symbols , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all." What may be the importance of the research? A) It shows sleep may help us manage information B) It helps find out the common themes of word C) It tells us that more sleep can improve health D) It proves the value of old-fashioned advice

Ques: When I was 23 years old I was in a dangerous relationship with the man who was my fiance at the time. I was being physically and verbally abused on a daily basis. I was financially tied to him after he spent all my savings to pay his debts but I wanted to be free! For the longest time I was too embarrassed to tell my mother about the situation. She had warned me about him. But, eventually, I worked up the courage to tell her and she sent me the money I needed to leave. Before the money arrived, he found out what I planned to do. I was so scared of what he might do that I decided to leave without taking all my belongings and just get out of there. Then, on my way to safety, my car died! I had automobile insurance (thanks to my mom) so I called the AAA and had them pull the car to a garage. It turned out the repair was going to cost $800 and the money my mom sent hadn't arrived by that point. The owner of the garage must have known something was up because he asked what was wrong. I told him a brief version of my story and promised him I could pay him in two days. He never told me his name but I will never forget him or what he did for me that day! He fixed the car immediately and told me he would not accept any payment ---- ever! He said he had a daughter almost my age and hoped that if she ever needed help in the future then some stranger might do the same for her. Since then I have tried to help people in my own way. Now I have a beautiful 12-year-old daughter and I hope throughout her life she can help others and be helped when she needs it, like I was! The author wanted to break up with her fiance because _ . A) he was too poor to support the family B) she was badly treated by him everyday C) he owed a lot of money to other people D) her mother had warned her about him

Ques:It was a village in India.The people were poor.However,they were not unhappy.After all,their forefathers had lived in the same way for centuries. Then one day,some visitors from the city arrived.They told the villagers there were some people elsewhere who liked to eat frog's legs.However,they did not have enough frogs of their own,and so they wanted to buy frogs from other places. This seemed like money for nothing.There were millions of frogs in the fields around,and they were no use to the villagers.All they had to do was catch them.Agreement was reached,and the children were sent into the fields to catch frogs.Every week a truck arrived to collect the catch and hand over the money.For the first time,the people were able to dream of a better future.But the dream didn't last long. The change was hardly noticed at first,but it seemed as if the crops were not doing so well.More worrying was that the children fell ill more often,and,there seemed to be more insects around lately. The villagers decided that they couldn't just wait to see the crops failing and the children getting weak.They would have to use the money earned to buy pesticides and medicines.Soon there was no money left. Then the people realized what was happening.It was the frog.They hadn't been useless.They had been doing an important job--eating insects.Now with so many frogs killed,the insects were increasing more rapidly.They were damaging the crops and spreading diseases. Now,the people are still poor.But in the evenings they sit in the village square and listen to sounds of insects and frogs.These sounds of the night now have a much deeper meaning.
