The skin which covers the tips of the fingers and thumbs is crossed by numerous ridges (隆起) arranged in different patterns. These patterns are permanent from birth and remain exactly the same throughout a person's life, even when the skin becomes wrinkled and cracked as a result of old age. Such patterns are never passed on from parents to children, and no one in the world has the same patterns as anyone else. Even identical twins have different sets of fingerprints. As a result, fingerprints offer a most useful and foolproof way of identifying people. Any ridged part of the hand and the foot may be used as a means of identification, but finger impressions are usually preferred since they can be taken easily and quickly.
Fingerprints are classified in the ways: by general shapes and contours(輪廓), by the finger positions of the pattern-types, and by size (often measured by counting the ridges in the loops). Every set of fingerprints has different “ridge characteristics” (i. e. the print of each separate finger is different from that of all the other fingers), which belong to one of four basic groups: arches, loops, whorls and composites. All fingerprints can then be divided into 1, 024 groups. By using details in the patterns above, these 1, 024 groups can be further divided into thousands of smaller groups, thus making it possible to find a particular set of fingerprints in a few minutes.
小題1:According to this passage, the true statement about human fingerprints is that ____.
A．people's fingerprints sometimes can be passed on from parents to children
B．people’s fingerprints are unique but identical twins may have the same fingerprints
C．using fingerprints is the only way to identify people
D．people's fingerprints will not change in all their lives
小題2:We prefer to use fingerprints to identify people because ____.
A．we can never find the same set of fingerprints among human beings
B．finger impressions can be taken easily and quickly
C．fingerprints offer a most useful and foolproof way of identifying people
D．all of the above
小題3:The word “foolproof” (Line 7, Para. 1) most probably means ____.
A．that is permanent　B．that is acceptable
C．that can not go wrong　D．that is not foolish
小題4:About the classification of fingerprints, which is TRUE? ____.
A．Fingerprints can be classified in three ways
B．All fingerprints can be divided into 1, 024 groups and can not be divided further
C．It is not easy to find a particular set of fingerprints in a short time
D．People can not classify the fingerprints in an effective way

小題1:D
小題2:D

One period of our lives when better results are demanded of us is, strangely enough, childhood. Despite being young we are expected to achieve good grades, stay out of trouble, make friends at school, do well on tests, perform chores (雜務)at home and so on. It’s not easy.
Likeable children enjoy many advantages, including the ability to deal more easily with stresses of growing up.In her book Understanding Child Stress, Dr. Carolyn Leonard states that children who are likeable and optimistic are able to gain support from others. This leads to focus and resilience（適應力）, the ability to recover from or adjust early to life stress. Much research shows that resilience has enabled children to succeed in school, avoid drug abuse, and develop a healthy self-awareness(自我意識).
Why does a likeable child more easily handle stress and do better in his or her life? Because likeability helps create what’s known as a positive feedback loop(回饋圈). The positive feelings you want to see in other people are returned to you, creating constant encouragement and motivation to deal with the daily stress of life.
This feedback loop continues into adulthood. To return once again to the example of teaching, learning becomes easier with a likeable personality. Michael Delucchi of the University of Hawaii reviewed dozens of studies to determine if likeable teachers received good ratings because of their likeability or because they in fact taught well. Delucchi found that “Students who perceive(察覺) a teacher as likeable, in contrast to(比照) those who do not, may be more attentive to the information that the teacher delivers and they’ll work harder on assignments, and they will learn more.”
You may have noticed this pattern in your own life when you try to give some advice. The more positive your relationship with that person, the more he or she seems to listen, and the more you feel certain that that person has heard you and intends to act on your words.
小題1:The writer implies in the first paragraph that __________.
A．life is not easy for every one of us
B．children are expected much than we usually think
C．better education results in smarter children
D．to be a likable child is almost impossible
小題2:According to Dr. Leonard, likeable children __________.
A．will work harder on assignments and learn more
B．can deal more easily with stress independently
C．can achieve more and understand themselves better
D．are always optimistic and ready to help those in need
小題3:The main purpose of the studies done by Michael Delucchi is to find __________.
A．how a likeable teacher’s teaching style is formed
B．how a teacher’s likeability gains popularity
C．if a likeable teacher draws more attention
D．if a likeable teacher has a positive personality
小題4:The passage aims at proving that __________.
A．likeable people give better advice
B．likeable people do better in their childhood
C．social creatures enjoy more advantages
D．likeable people do better in life generally

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（半導體）．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（晶體結構） 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．
小題1:Jae Kwon gave examples in Paragraph 4_________．
A．to show chemical batteries are widely applied．
B．to introduce nuclear batteries can be safely used．
C．to describe a nuclear-powered system．
D．to introduce various energy sources．
小題2:According to Jae Kwon, his nuclear battery _______．
A．uses a solid semiconductorB．will soon replace the present ones．
C．could be extremely thinD．has passed the final test．
小題3:The text is most probably a ________．
A．science news reportB．book review
C．newspaper adD．science fiction

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.
Without having a nature experience, kids, can turn out just fine, but they are missing out a huge enrichment of their lives. That contributes to everything from their physical health and mental health, to stress levels, creativity and cognitive (認知的) skills. Experts predict modern kids will have poorer health than their parents---and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component(成份) and that play in nature develop leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child. The three-year-old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.
Kids are not to blame. They are overprotected and frightened. It is dangerous out there from time to time, but much stress from computers is replacing breaking an arm as a childhood process of passage.
Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that strengthen love, respect and need for landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause.
小題1:According to the passage, children without experiencing nature will______
A．keep a high sense of wonder
B．be over-protected by their parents
C．be less healthy both physically and mentally
D．change wild places and creatures for the better
小題2:According to the author, children’s breaking an arm is_____
A．the fault on the part of their parents
B．the natural experience in their growing up
C．the result of their own carelessness in play
D．the effect of their repetitive stress from computers
小題3:In writing this passage, the author mainly intends to______
A．blame children for getting lost in computer games
B．encourage children to protect parks from encroachment
C．show his concern about children’s lack of experience in nature
D．inspire children to keep the sense of wonder about things around

Busy senior managers need no longer waste time in showering themselves－an Australian company has invented a suit that can be worn while they wash.
The suit has been specially designed so that it can be cleaned under the showerhead. There is no need for soaking (浸泡)，dry cleaning－or even soap.
The Japanese market has taken a liking to the “shower suit”，described as “revolutionary” by its owner Australian Wool Innovation (AWI)，which is the research and marketing body that represents Australian wool－growers. Orders have been placed for 170,000 of the woolen suits.
The suit could be worn in the shower，although it was probably better to hang it on a clothes hanger and carry it instead，AWI corporate affairs spokesman Stephen Feighan said.“The idea is that you hang it up and then...you give it a spray (噴霧)，and it’s dry the next morning，” Mr Feighan said.
A Japanese researcher working for AWI invented the suit by combining three technologies. The secret is the best lining (內襯)，which allows the suit to dry quickly.The shower suit attracted busy corporate people，particularly those who often traveled or stayed up late，Mr Feighan said.The airline industry was also interested.
Mr Feighan confessed he had not worn one of the suits yet，or tried to wash it in the shower，because they cut to fit Japanese figures.AWI believes that the shower suit will spread from the Japanese market through Europe and India. Mr Feighan hoped the suit，made from local wool，would be available in Australia in 12 to 18 months’ time.
小題1:What is the writing purpose of the article?
A．To introduce a newly－designed shower suit.
B．To help the white collars arrange their life more sensibly.
C．To provide suggestions on saving time in bath.
D．To praise AWI for its important achievement.
小題2:Which is true about the suit according to the passage?
A．It can spare the owner’s trouble of soaking，dry cleaning and applying soap.
B．It is of the quality of fast dry for its best cloth.
C．It is not suitable for hanging.
D．It has attracted more orders than any other suit.
小題3:The suit draws the attention from all the following groups EXCEPT________.
A．corporate people who are always on the go
B．people on occasional business trips
C．the airline industry
D．people burning the midnight oil
小題4:Which of the following has much to do with Mr Feighan?
A．The invention of the suit.
B．The try－on of the suit.
C．The combination of the three technologies on the suit.
D．The popularization of the suit and best wishes for it.

I had the meanest mother in the world. While other kids ate candy for breakfast, I had to have cereal, eggs and toast. Others had cokes and candy for lunch, while we had to eat a sandwich. As you can guess, my supper was different than the other kids’. But at least I was not alone in my suffering. My sister and two brothers had the same mean mother as I did.
My mother insisted on knowing where we were at all times. She had to know who our friends were and what we were doing. We had to wear clean clothes every day. Other kids always wore their clothes for days. We reached the height of disgrace because she made our clothes herself, just to save money.
The worst is yet to come. We had to be in bed by 9:00 each night and up at 7:45 the next morning. So while my friends slept, my mother actually had the courage to break Child Labor Law. She made us work. I believed she lay awake all night thinking up mean things to do to us. Through the years, our friends’ report cards had beautiful colors on them, black for passing, red for failing. My mother, however, would merely be content with black marks. None of us was allowed the pleasure of being a dropout.
She forced us to grow up into educated and honest adults. Using this as a background, I’m now trying to bring up my three children. I’m filled with pride when my children think I am mean because now I thank God every day for giving me the meanest mother in the world.

You will spend hours at the gym training your body, but do you ever think about training your brain? Here are four ways to keep your brain mentally (腦力上地) active and healthy.
Play games
Your brain is a muscle just like the ones in the rest of your body. If you don’t use it, you will lose it. For example, doing a crossword puzzle (縱橫填字游戲) once a day is a good way to give the brain the exercise it needs. This kind of puzzle is good at training different areas of the brain. But remember that when doing this puzzle, you should gradually increase the complexity (復雜度); otherwise, it will become repetitive (重復乏味的) and stop being mentally challenging.
Talk aloud
Although it might sound strange to you, talking aloud is a great way to boost your memory. A good exercise to try is counting to 99 in threes as fast as you can.
Be a team leader
If you find you can do your work very easily, you should find a new task. It is important that your job should be mentally challenging. Complex jobs are often more challenging and make the brain work a little harder.
Learn a language
A study found that, compared with those who could speak only one language, the people who could speak two languages had a slower rate of cognitive (認知能力) decrease. Learning a new language is very challenging and it makes sure that different areas of the brain have their lights on.
小題1:What is the main idea of this passage?
A．Why you should train your brain.
B．How to be a good team leader.
C．Training the brain is more important than training the body.
D．How to make your brain healthy and work actively.
小題2:Which word can replace the word "boost" in the third paragraph?
A．Change.B．Promote. C．Decrease.D．Lose.
小題3:We should gradually increase the complexity when doing crossword puzzles because ______.
A．if we don’t use our brain, we will lose it
B．we should make our brain face different challenges
C．our brain is a muscle like other parts in our bodies
D．these puzzles can work on different areas of the brain
小題4:Which group of people have a slower rate of cognitive decrease?
A．Those who don’t often do crossword puzzles.
B．Those who don’t often count to 99 in threes.
C．Those who do their work very easily.
D．Those who can speak more than one language.
