A great French writer has said that we should help everyone as much as we can because we often need help ourselves. The small even can help the great. About this, he told the following story.

With a pity, the bird threw a piece of wood. With it the ant reached the bank again. While she was resting and drying herself in grass she heard a man coming up. He was walking without shoes on his feet and carrying a gun in his hand. As soon as he saw the bird, he wished to kill her, and he would certainly do so, but the ant bit him in one of his feet and at that moment the bird flew away at once. It was an animal much weaker and smaller than the bird herself that had saved her life. The title of this story can be " _ ". A) The Ant B) Pity C) Help D) The Bird

In the hot jungles of Thailand, forest rangers came across a terrible sight one day in 2010. Two tiger cubs lay dead in a wildlife preserve . The rangers were too late to find the cubs' mother. All that remained of her was blood on the ground. Poachers had poisoned the tigers. Then they ran off with the mother's body. If the rangers had not arrived, the poachers would have taken the cubs too. Tigers in trouble One hundred years ago, there were about 100,000 tigers. Today, only about 3,200 remain in the wild. Poachers are a major problem. These killers sell tiger fur, teeth, claws, and other body parts in illegal markets. One tiger's parts can see for $50,000. Because they hunt in huge jungles thick with trees, poachers are hard to find. But they must be caught, says Elizabeth Bennett of the Wildlife Conservation Society. This group works to help endangered animals. Tiger "fingerprints" Finally, after many months, the rangers spotted the poachers again. After an exchange of gunfire, they arrested the criminals. Soon, the police found evidence that the poachers had killed again. The evidence came from a cell phone. On a poacher's phone, police found photos of the men posing with a dead male tiger. The poachers claimed that the photos were from a nearby country where tigers aren't protected. But another photo told a different story. Deep in the Thai forest, the rangers had set up camera traps, which take photos when they sense movement. A camera trap photo showed the same male tiger walking through a wildlife preserve before he was killed. That meant that the tiger came from a protected area. But how could police prove it was the same tiger? Tiger stripes are like fingerprints. No two patterns are the same. When police compared the photos, the stripes on the tiger's head matched. The poachers were given up to five years in prison. That might not seem like much for killing tigers. But since the poachers were caught in July 2011, no tigers have been killed in that wildlife preserve. The author's purpose of writing this story is probably to _ . A) inform readers about poaching B) entertain readers with a funny story C) persuade readers to become rangers D) instruct readers on using cell phones

Q: We spend a quarter of our lives asleep. Sleep is necessary for the body to rest, yet our brains continue to process information. Studies have shown that students are more successful when they sleep after studying-instead of pulling all-nighters-because the brain reviews information learned. Similarly, dreaming is an opportunity to work out emotional problems and form thoughts and memories. About 25 percent of the time spent sleeping is spent in rapid eye movement, or REM, sleep. This type of sleep is known for when dreams occur, but it also helps energize the brain and body. Researchers have found two important factors regarding humans and sleep: basicsleep need and sleep debt. Basic sleep need is the amount of sleep we need to have regularly to perform at our best. Sleep debt is the loss of sleep. A few studies say that most adults function best with a basic sleep need of seven to eight hours a night. The problem is that sleep debt also factors in, just because that you meet your basic sleep needs a few nights of the week doesn't mean it cancels out the effects of one night's sleep debt. Of course, everyone is different and some people require more or less sleep than the standard basic sleep need. But the real problem lies in what lack of sleep does over the long period to people who either does not meet his or her body's needs or for one reason or another doesn't get enough regular sleep. It is more possible for these people to have motor vehicle accidents, weight gain and risk for heart disease or diabetes and may be at increased risk for psychological conditions such as depression or drug abuse. Sleeping too long also can be associated with depression and poor health. Most peoplespent around _ of the sleeping time in REM sleep? A) One third of the time B) More than half of the time C) One fourth of the time D) More than 5 hours every day
A: C
*Question*
Boys at the top of the pecking order either by birth or because their older brothers died score higher on IQ tests than their younger brothers. Norwegian researchers now report that it's a matter of what they call social rank in the family that gives the first born the highest scores or, if the first born had died young, the next oldest. Kristensen and Bjerkedal studied the IQ test results of 241,310 Norwegian men drafted into the armed forces between 1967 and 1976. All were aged 18 or 19 at the time. The average IQ of first-born men was 103.2, they found second-born men averaged 101.2, but second-born men whose older brother died young scored 102.9. And for third-borns, the average was 100.0. But if both older brothers died young,the third-born score rose to 102.6. The findings provide "evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such." they concluded. _ since at least 1874,when Sir Francis Galton reported that men in noticeable positions tended to be firstborns more often than would have been statistically expected. Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports. "These two researchers prove that how study participants were raised, not how they were born, is what actually influences their IQs," said Sulloway, an American professor, who was not part of the research team. "The elder child pulls ahead," he said, "perhaps as a result of learning gained through the process of tutoring younger brothers and sisters". "The older child benefits by having to organize and express its thoughts to tutor youngsters", he said, "while the later born children may have no one to tutor." According to Kristensen and Bjerkedal's test results, parents can make youngsters smarter by _ . A) treating them as the oldest child B) teaching them as the oldest child C) talking to them as much as possible D) encouraging them to express thoughts
