One day an ant was drinking at a small stream and fell in. She made desperate efforts to reach the side, but made no progress at all. The poor ant almost exhausted was still bravely doing her best when a dove saw her. Moved with pity, the bird threw her a blade of grass, which supported her like a raft, and thus the ant reached the bank again. While she was resting and drying herself in the grass, she heard a man come near. He was walking along barefooted with a gun in his hand. As soon as he saw the dove, he wished to kill it. He would certainly have done so, but the ant bit him in the foot just as he raised his gun to fire. He stopped to see what had bit him, and the dove immediately flew away. It was an animal much weaker and smaller than herself that had saved her life.

    While music has value all by itself, researchers have long noticed that musicians also tend to be better at learning languages and show other improved reading and math abilities. Now a new study from the University of Washington by Christina Zhao shows that rhythm is an important bridge between music and speech as early as nine months of age.

    Researchers randomly placed babies into two groups of 20 each, and each group played at the lab with their parents for a dozen 15-minute sessions over a month.

    In one group, researchers played recordings of songs with a waltz rhythm and showed the parents how to help their babies tap out that 1-2-3 beat in time with the music on boy drums or with their feet. In the other group, children played with typical toys and no music.

    The babies in the music group were better able to detect random mistakes in that rhythm when they heard it within two weeks of the last session. They also showed a stronger brain response to disruptions in the rhythm. For example, researchers would sometimes alter the timing of syllables(音节) by slightly shortening the middle sound of a word like bibbi to make it bibi—and the babies with music training were more likely to notice it.

    In other words, music training not only improved the babies' ability to notice when a musical rhythm skipped a beat, but also improved their ability to notice when the rhythms of speech changed unexpectedly, an important skill for learning to talk.

    The study reflects Zhao's personal experiences as a pianist who music in college, and as someone who speaks both Mandarin and English. She noticed that a lot of her fellow musicians were also good at learning other languages. “That really got me wondering how these two are related, “Zhao said.

    Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

    Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.

    Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our Study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see一and guide whether we see fear.”

To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.

“We have found an important mechanism by which the heart and brain ‘speak' to each other to change our feelings and reduce fear,” Dr Garfinkel said.

    “We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”

    Since many of you are planning to study at a college or university in the future, you may be curious to know what your future study will be like. This is the question I want to discuss with you today.

    First, let's talk about what your weekly timetable will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lecture. Lectures are usually in very large rooms because some courses such as Introduction to Sociology or Economics often have as many as two or three hundred students, especially at large universities. In lectures, it's very important for you to take notes on what the professor says because the information in a lecture is often different from that in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn't enough to just read your textbooks; you have to attend lectures as well. In a typical week, you will also have a couple of hours of discussion for every class you take. The discussion part is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students called teaching assistants, usually direct discussion parts

    If your major is chemistry, or physics, or another science, you'll also have to spend several hours a week in the lab doing experiments. This means that science majors spend more time in the classroom than non-science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do.

    People who have seen Trisha Seifried Woodall with her cats say that she has a magic touch. Most people don't know anyone who can order a cat to jump on a table, sit for two minutes, and then jump to the floor and walk backward.

    Ms. Seifried Woodall has taught her cats to do all these tricks -- and many more. At her training center. Got Pet-ential, cats learn tricks for TV and magazine ads. Some of her cats have appeared on bags of cat food.

    When Ms. Seifried Woodall gets a cat, she first learns what that cat likes and doesn't like. "Some cats like to stay close to the ground, so I'll teach them how to stand behind me, and walk with me," she says. "Other cats, like high places, so they'll learn how to jump on my bent knee and then safely leap to my shoulder."

    Ms. Seifried Woodall grew up in a family with many pets, and she was first paid to work with animals when she was 18. At a summer job at an amusement park, she learned how to train a few of the animals for performances. She continued to train and learn about animals for 20 years before starting her own animal-training center.

    Ms. Seifried Woodall is proud of the skills her cats have learned, but she is also proud that her center's cats are healthy and social. She believes her cats enjoy learning new tricks.

    In Ms. Seifried Woodall's experience, no breed (品种) of cat is easier to train than others. All of her cats came from shelters. They have become pets in her home.

    Like most animal trainers, Ms. Seifried Woodall uses a reward system. Cats that are successful during training get food or a new toy. A cat that doesn't enjoy eating or playing will probably not be interested in being trained. She never scolds (责骂) them. "Cats need a lot of encouragement when they are performing, she says." I say good job or that s right several times during a single minute."

    It is rightly said that one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend's secrets to yourself and not telling the world is what makes the bond(关系)grow strong and last forever. You need to develop trust and mutual(互相的)understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend's mind.

    There is a certain time in life especially from the teenage years when one starts having a personal periphery(界限) in life and parents are excluded (排斥)from it. It is because there are certain things that they can't understand and we can't discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one's feelings and best kept secrets.

    It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range(变化) from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.

    Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.
