Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
"To provide enough power, we need certain methods with high energy density(密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU. "The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
"People hear the word ‘nuclear' and think of something very dangerous," he said, "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems."
His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.
"The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem."
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

（1）、Which of the following is true of Jae Kwon?

A、He teaches chemistry at MU. B、He is working on a nuclear energy source. C、He developed a chemical battery. D、He made a breakthrough in computer engineering.

（2）、Jae Kwon gave examples in Paragraph 4 _________.

A、to introduce nuclear batteries can be safely used B、to show chemical batteries are widely applied C、to introduce various energy sources D、to describe a nuclear-powered system

（3）、Liquid semiconductor is used to _________.

A、get rid of the radioactive waste B、test the power of nuclear batteries. C、reduce the damage to lattice structure. D、decrease the size of nuclear batteries

    If your child constantly moves when he's doing math homework or insists on listening to music while studying, take heart. Although it may seem like he's trying to drive you crazy, he's probably just using the strategies that help him learn.
    “I like to study at a desk in silence, and my daughter can't think that way. She likes to bounce around on a ball with music in the background,” says author Maureen McKay, whose website, Optimistic Outcomes, provides tips based on a child's learning style for parents. “Sometimes kids are just doing what works for them.”
    Three basic learning styles are auditory, kinesthetic(肌肉运动知觉的), and visual ones. Auditory learners prefer listening to explanations to reading them and may like to study by reciting information aloud. This type of learner may want to have background music while studying, or they may be distracted by noises and need a quiet environment to study. Kinesthetic learners learn by doing and touching something. They may have trouble sitting still while studying, and they are better able to understand information by writing it down or doing hands-on activities. Visual learners process new information by reading, looking at graphics, or watching a demonstration. Children with this learning style can grasp information presented in a chart or graph, but they may grow impatient listening to an explanation.
    Most people use a combination of styles but have a clear preference for one. Understanding your child's learning style can reduce homework frustrations and make it easier for families to communicate, says McKay. She observed different learning styles while working as a teacher's assistant, and she started researching strategies for working in different learning styles when her daughter began having trouble in elementary school.
    Because her daughter had difficulty listening in class, McKay looked for exercises to strengthen listening skills. Her daughter is now doing well in middle school, and she owes her success to the fact that her teachers and parents came to understand her unique style of learning.

Spider monkeys have long, thin arms with hook like hands that allow them to swing through the trees. They do not have opposable thumbs(对生拇指).

The brown-headed spider monkey has a prehensile(缠绕性的)tail, which means it can grasp and can be used like a fifth leg to grab trees. During the day, the spider monkey searches for fruits, which make up the main part of its diet. They will also eat flowers, seeds, leaves, and small insects during the dry season when fruits aren't available. They spend most of the daylight hours climbing and swinging through the high branches of trees.

The brown-headed spider monkey lives in a large community of about 20 to 100 male and female monkeys. They split into smaller groups for feeding. Females usually give birth to only a single baby each year or two. Young monkeys are carried on their mothers' stomachs until about 16 weeks old. Then they are strong enough to ride on their mothers' backs. All brown-headed spider monkey babies are born with a pink face and ears.

Spider monkeys hug each other and wrap their tails around each other. They are very intelligent and have strong memories. They were named spider monkeys because they look like spiders as they hang upside down from their tails with arms and legs swinging. Their genus (属)name is Ateles, which means “imperfect”. This refers to the fact that they don't have thumbs.

Hunting the brown-headed spider monkey is now barred in Ecuador, a country in northwestern South America, but humans have killed them for their meat for hundreds of years.

Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are excessively concerned with their own appearance and actions.

Worrisome thoughts are constantly occurring in their minds: what kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes? It is obvious that such uncomfortable feelings must negatively affect people. A person's conception of himself or herself is reflected in the way he or she behaves, and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a profound effect on all areas of their lives.

Shy people, having low self-esteem, are likely to be passive and easily influenced by others. They need reassurance that they are doing "the right thing." Shy people are very sensitive to criticism; they feel it confirms their feelings of inferiority. They also find it difficult to be pleased by compliment with a statement like this one, "You're just saying that to make me feel good. I know it's not true." It is clear that while self-awareness is a healthy quality, overdoing it is harmful.

Can shyness be completely eliminated, or at least reduced? Fortunately, people can overcome shyness with determined and patient efforts in building self-confidence. Since shyness goes hand in hand with a lack of self-esteem, it is important for people to accept their weaknesses as well as their strengths. Each one of us is a unique, worthwhile individual, interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our full potential. Let's not allow shyness to block our chances for a rich and fulfilling life.

The Shepherd's Life by James Rebanks

Reviewed by Helena

No lyrical, romantic account, but a hard-bitten, dull and down-to-earth story of a family, a community and an environment. A story of cycles—of seasons, years, people, generations, stretches back centuries.

A story of farming which only exists now in the remoter, wilder region of the UK, where the land is too hard and the environment too harsh for farming to be an "agribusiness". Where success, survival of farms, their sheep are dependent on knowledge passed down through generations and shared between farmers and shepherds in a small, close-knit and mutually-dependent community. A story of people hefted to their land every bit as much as their sheep are hefted to their fells.

A Walk in the Woods by Bill Bryson

Reviewed by T. Bently

Having read all of Bill Bryson's travel books, this was the last one left. I hadn't read this because I had been told it was one of his weakest one. But I decided, through no other reason that I needed a hit of Bryson, to read it. People couldn't have been more wrong. From the very beginning of assessing the feasibility, arranging for Katz to accompany him to the purchasing of his equipment and the purchasing of “a large knife for killing bears and hillbillies”, Bryson is at his absolute best. His cute eye-is a wise witness to this beautiful but fragile but fragile trail. His encounters along the trail and Katz anti-social, childish antics(滑稽动作) make the first 150 pages more than a laugh-out-loud-hike. I couldn't have been more surprised. An adventure, a comedy, and a celebration, A Walk in the Woods is destined to become a modem classic.
