    For years,Hagelin has studied what role scents（气味）play in wild birds' behavior.In 2010,Hagelin heard Jan Straley,a marine biologist,talk about the behavior of whales.Straley mentioned that whales often leap into the air,but nobody knew why.

    The mystery interested Hagelin.So Hagelin asked Straley whether they might leap to smell the air—maybe to locate food or look for danger.Straley replied that it was an interesting idea but there wasn't much evidence that whales have a sense of smell.To investigate the idea further,the two scientists teamed up.

    In the summer of 2011,they set up a post on the coast of southern Alaska.The researchers spent hours monitoring the direction of the whales and of the wind.The whales headed into the wind half of the time.This didn't prove that whales leap to smell,but it suggested that it is possible.

    Meanwhile,other researchers in Alaska were studying a region of the brain called the olfactory bulb（嗅觉球）in whales.Olfaction means the ability to smell.Humans also process smells in the olfactory bulb.

    In identifying a scent,you might think the nose does all of the work.However,the major role of a nose is to draw chemicals on the air and pass them across sensing cells.As chemicals come into contact,they give signals that travel directly to the bulb and then in the brain for further interpretation.

    The researchers discovered that the bulb in a whale was more complex than the one in a human.In whales,this smell-processing center takes up a share of the brain six times larger than it does in humans.

    The brain research suggested that whales probably can smell just as well as people—and possibly better than humans can.It is supposed that a good sense of smell could help them find food more easily.

    However,Hagelin is not sure of that.Now he is planning a new study that will examine whether whales do use the sense of smell to find food.

    It was dawn of March 21, 2018. Gary Messina was on his morning run along New York City'8East River. Suddenly something caught his eye—a large 60-year-old man balancing on the four-foot-high fence that guarded the path from the water. As Messina got closer to the scene, the man took a step forward and slipped into the dark river below.

    When Messina reached nearer, the man was struggling in the water, clearly unable to swim. Other joggers also heard the man's cry. David Blauzvern and John Green dropped their phones and keys on land and jumped in. “ People had called the police, but it was unclear when they'd get there,” says Green. “We just reacted. Messina joined them in the river. Just as the jumper was losing strength, Blauzvern take hold of him. The pair were about 30 yards from the seawall when Messina and Green caught up to them. They seized the man, with Blauzvern supporting his back and Messina and Green holding him up from either side. As the men made their way toward the concrete seawall that stretched for blocks in each direction, Blauzvern had an awful realization:there was no way out of the river.

    By now, a crowd had gathered on land. “A rescue boat is on its way, someone yelled to them. Swimming forward was getting tougher by the minute. The jumper, who was six foot two and weighed around 260 pounds, was heavy in his rescuers' arms. After ten minutes, they managed to get to the river's edge. “I've never been so out of breath, ”says Blauzvern.

    Fifteen minutes after the men had jumped into the river, the two-man rescue boat appeared. But because it couldn't risk getting too close to the seawall, the men had to swim out to it. “I was completely out of energy at this point, “says Blauzver. The men in the water pushed the jumper while the men in the boat pulled him up and, finally, to safety. The man they had saved was taken to the hospital for evaluation(评估). Details on his condition have not been released. As for the rescuers, each of them was at work by 10:30a. m. “I was a bit late,” admits Blauzvern, smiling. “But I had a good excuse.”

    If you do not use your arms or your legs for some time, they become weak. When you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.

    When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.

    If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to be blamed(责备), and few of us know that it is just his own fault.

    Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write them down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: practice remembering.

    He is regarded as having one of the brightest minds on the planet. But outstanding astrophysicist (天体物理学家) Stephen Hawking has admitted that he did not learn to read until he was eight years old.

    In a public lecture at the Royal Albert Hall, Professor Hawking also admitted that he was not active in studying while at Oxford University, where he studied physics, and that only the diagnosis that he might die young from motor neurone (神经元) disease made him concentrate on his work.

    Professor Hawking said: "My sister Philippa could read by the age of 4 but then she was definitely brighter than me." He said that he was unexceptional at school and was never further than halfway up his class. "My classwork was very untidy, and my handwriting was the despair of my teachers," he said. "But my classmates gave me the nickname Einstein, so presumably they saw signs of something better."

    But he said that it was when doctors told him that he probably only had a few years to live at the age of 21 that galvanized him into focusing on his work and a period of productivity that resulted in some of his early breakthroughs. He said, "When you are faced with the possibility of an early death, it makes you realize that life is worth living and there are lots of things you want to do."

Having a study partner has many advantages. Of course, you can always study alone at home. But you'll miss the benefits that come from learning with a friend or two. Why should you think of finding a study partner or a study group? {#blank#}1{#/blank#}

It can reduce distractibility(注意力分散).

Staying focused is one of the biggest challenges students have to overcome. When you have a study partner, it will be easier to achieve. With common goals in mind, you will focus on the result. 

You understand the material faster than alone.

Besides staying focused and learning faster, you can benefit from testing each other. Quizzing(测验) before the exam can help both of you to find out the areas that need more attention.

Learning becomes organized yet fun.

Last but not least, it can be enjoyable to share your study journey with another person. Long evenings in the library will seem less lonely if you're with a friend. {#blank#}5{#/blank#}It will turn the learning into a fun yet organized process.
