“In real life, the daily struggles between parents and children are around these narrow problems of an extra hour, extra TV show, and so on” said Avi Sadeh, psychology professor at Tel Aviv University. “Too little sleep and more accidents,” he said.Sadeh and his colleagues found an extra hour of sleep can make a big difference. The children who slept longer, although they woke up more frequently during the night, scored higher on tests, Sadeh reported in the March/April issue of journal Child Development. “When the children slept longer, their sleep quality was somewhat weak, but in spite of this their performance for study improved because the extra sleep was more important than the reduction in slee
p quality. ”Sadeh said. “Some studies suggested that lack of sleep as a child affects development into adulthood and it’s more likely to develop their attention disorder when they grow older. ”
In earlier studies, Sadeh’s team found that fourth graders slept an average of 8.2 hours and sixth graders slept an average of 7. 7 hours. “Previous research has shown children in elementary school need at least nine hours of sleep a night on a regular basis, said Carl Hunt, director of the National Center on Sleep Disorders Research in Bethesda, and high-school-age children need somewhat less, he said, adding that the results of lack of sleep could be serious.
“A tired child is an accident waiting to happen,” Hunt said. “And as kids get older, toy get bigger and the risks higher. ” Hunt also said too little sleep could result in learning and memory problems and long-term effects on school performance. “This is an important extension of what we already know, ” Hunt said of Sadeh’s research, adding sleep is as important as nutrition(营养) and exercise to good health. “To put it into reality,” Hunt said, “parents should make sure they know when their children actually are going to sleep and their rooms are helpful to sleep instead of playing. ”

Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms．Yet etymologists actually have a uniquely interesting job．They are in many ways just like archaeologists (考古学家) digging up the physical history of people and events．The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind．
The English language, in particular, is a great field to explore history through words. As a language, English has an extraordinary number of words．This is partly due to its ability to adapt foreign words so readily．For example, "English" words such as kindergarten (from German), croissant (from French), and cheetah (from Hindi) have become part of the language with little or no change from their original sounds and spellings. So English-language etymologists have a vast world of words to explore．
Another enjoyable thing about etymology for most word experts is solving word mysteries(谜)．No, etymologists do not go around solving murders, like the great detective Sherlock Holmes．What these word experts solve are mysterious origins of some of our most common words
One of the biggest questions English language experts have pursued is how English came to have the phrase OK．Though it is one of the most commonly used expressions, its exact beginning is a puzzle even to this day．Even its spelling is not entirely consistent-unless you spell it Okay, it is hard even to call it a word．
Etymologists have been able to narrow OK’s origin down to a likely, although not certain, source(来源)．It became widely used around the time of Martin Van Buren's run for president in 1840. His nickname was Old Kinderhook. What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well known．It is likely that Van Buren could be called its primary source Etymologists will doubtlessly keep searching for the initial source．However, it is clear that OK’s popularity and reputation have topped those of the American president to whom it has been most clearly linked．The author mentions the words like "croissant" in Paragraph 2 to indicate________．
| A．words have changed a lot in the two languages |
| B．what English-language etymologists are exploring now |
| C．English has absorbed many words from other foreign languages |
| D．the English vocabulary is difficult to the non-English-speaking people |
The underlined word "pursued" in Paragraph 4 means___________．
| A．looked upon | B．dug up | C．put in | D．set down |
We can learn from the passage that etymologists_______．
| A．discover the possible origin of words |
| B．help detectives to solve mysterious murders |
| C．write interesting stories for some newspapers |
| D．explore the English language as well as the recent events |
What is the main purpose of the passage?

Charles Dickens is often thought of as one of the greatest British writers.February 7 marked the 200th anniversary of his birthday. Yet for many, his language is old-fashioned and his stories often improbable. So why do so many people know and read Dickens today?
One reason is the British government's insistence that every child studies a Dickens novel at school. Alongside William Shakespeare, Dickens is on every English literature school reading list.His stories, though often long by today's standards, are great moral tales. They are filled with colorful characters.
Earlier this month a ceremony was held in Portsmouth ,where Dickens was born Prince Charles said at the ceremony, Dickens used his creative genius to campaign passionately for social justice, his characterization is a fresh today as on the day is was written.
His books stand out from many other writers because of his insight into human nature. Dickens like Shakespeare tells us truths about human behavior. They are as true in the 21st century as they were to his readers in the 19th century.
Readers have returned to Dickens’ books again and again over the years to see what he has to say about their own times.
No surprise then that it was Dickens whom Britons turned to during the economic crisis in the last couple of years. Dickens helped them make sense of a world that was rapidly falling apart. The BBC adapted one of his less well-known novels, Little Dorrit, into a popular television drama thatintroduced many Brits to the novel for the first time. A dark story about greed and money, it was the perfect illustration of bad times.
As long as Dickens’s novels have something to say to modern audiences, it seems likely that he will remain one of Britain’s best-loved writers.In the article, the author intends to tell us ______.
| A．why Dickens’ novels still appeal to readers in modern times |
| B．that Dickens’ works are no longer popular among young people |
| C．why the British government puts Dickens on school reading lists |
| D．that Dickens and Shakespeare’s works are required for study at school |
In Britain, people still read Dickens because of ______.
a) romance in his books
b) moral value in his books
c) his colorful characters
d) his insight into human nature
e) government education requirement
f) his prediction of the current economic crisis
| A．abdf | B．bcde | C．bdef | D．abed |
We can infer from the article that ______.
| A．it’s better to read Dickens in time of difficulty |
| B．Dickens was a great social observer of his time |
| C．human nature seems worse during bad times |
| D．Dickens’s novels are short and easy to read |

| D．Dickens’ novels are still of realistic significance to today’s world. |
Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half - dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else-there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased(停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.
What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. “In the sweat of the face shall you eat the bread."
To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.Which of the following is indicated in the first paragraph?
| A．Wealth results from honest effort. |
| B．The men seated at tables in the locker room are lost in the significance of life. |
| C．For some people, no way can be found to escape the realities of life other than scotch and soda. |
| D．The men acquire wealth by planting fruit trees. |
The underlined sentence "In the sweat of the face shall you eat the bread " means ____.
| A．Bread tastes delicious when sweat pours off your face |
| B．No pains, no gains |
| C．Failure is the mother of success |
| D．Bread comes from the sweat on your face |
We learn from the passage that the author_______.
| A．was a wealthy person in the community |
| B．held a positive attitude towards an active life |
| C．was fond of associating with celebrities (名人) |
| D．kept a secret of the reason why he was so impressed |
What is implied in the passage by the writer?
| A．To use wealth properly, eat, drink and be merry. |
| B．Where there is a will, there is a way. |
| C．As life is but like a dream, a man is like a fruit tree. |
| D．If you cease to struggle, you cease to live. |
“Does my smile look big in this?” Future fitting-room mirrors in clothing stores could subtly adjust your reflection to make you look ─ and hence feel ─ happier, encouraging you to like what you see.
That’s the idea behind the Emotion Evoking System developed by Shigeo Yoshida and colleagues at the University of Tokyo in Japan. The system can manipulate, or in other word, control your emotions and personal preferences by presenting you with an image of your own smiling or frowning face.
The principle that physiological changes can drive emotional ones ─ that laughter comes before happiness, rather than the other way around ─ is a well-established idea.
The researchers wanted to see if this idea could be used to build a computer system that manipulates how you feel. The system works by presenting the user with a web-camera image of his or her face ─ as if they were looking in a mirror. The image is then subtly altered with software, turning the corners of the mouth up or down and changing the area around the eyes, so that the person appears to smile or frown (皱眉).
Without telling them the aim of the study, the team recruited (招募) 21 volunteers and asked them to sit in front of the screen while performing an unrelated task. When the task was complete the participants rated how they felt. When the faces on screen appeared to smile, people reported that they felt happier. On the other hand, when the image was given a sad expression, they reported feeling less happy.
Yoshida and his colleagues tested whether manipulating the volunteers’ emotional state would influence their preferences. Each person was given a scarf to wear and again presented with the altered webcam image. The volunteers that saw themselves smiling while wearing the scarf were more likely to report that they liked it, and those that saw themselves not smiling were less likely.
The system could be used to manipulate consumers’ impressions of products, say the researchers. For example, mirrors in clothing-store fitting rooms could be replaced with screens showing altered reflections. They also suggest people may be more likely to find clothes attractive if they see themselves looking happy while trying them on.
“It’s certainly an interesting area,” says Chris Creed at the University of Birmingham, UK. But he notes that using such technology in a shop would be harder than in the lab, because people will use a wide range of expressions. “Attempting to make slight differences to these and ensuring that the reflected image looks believable would be much more challenging,” he says.
Of course, there are also important moral questions surrounding such subtly manipulative technology. “You could argue that if it makes people happy what harm is it doing?” says Creed. “But I can imagine that many people may feel manipulated, uncomfortable and cheated if they found out.”What’s the main purpose of the Emotion Evoking System?
| A．To see whether one’s feeling can be unconsciously affected. |
| B．To see whether one’s facial expressions can be altered. |
| C．To see whether laughter comes before happiness. |
| D．To replace the mirrors in future clothing-store fitting rooms. |
What can we learn about the web-camera image in the study?
| A．It recorded the volunteers’ performance in the task. |
| B．It gave the volunteers a false image. |
| C．It attempted to make the volunteers feel happier. |
| D．It beautified the volunteers’ appearance in the mirror. |
What does Creed mention as a limitation of the technology?
| A．It only changes the areas around the mouth and the eyes. |
| B．It only works in clothing stores. |
| C．It only makes subtle changes to people’s expressions. |
| D．It only deals with a limited number of facial expressions. |
What does Creed’s comment on the moral issues with this technology imply?
| A．Nothing is more important than happiness. |
| B．Technology is unable to manipulate people. |
| C．People should make their decisions independently. |
| D．People should neglect the harm of the technology. |
The Zebra Finch: An Owner’s Guide to a Happy Healthy Pet
The zebra finch, a native of Australia, is a popular domestic pet in the United States. The bird has many attributes (特性) which allow it to be kept at home, though there are also a few negative aspects. The attributes are nest-building, breeding and a lively attitude. The potential negatives are over-breeding and the wildness of the birds.
One of the main attributes of zebra finches is their ability to breed. They are the rabbits of the domestic bird world. Once you have two birds, male and female, you will soon have six, as they breed quite easily and have strong babies, usually four at a time. An added attribute is their ability to build their own nests. You can place branch in their place along with some kind of structure, and they will create a nest on their own. It’s very pleasant to see the ways males and females divide some labors and share others, and the babies grow up quickly. Overall, zebra finches are energetic birds, and they can make every place where they live delightful lives.
On the negative side, they will breed and in-breed. Often, in-breeding does little harm and does not cause genetic defects (缺陷), as happens more often in other species. However, no one can tolerate just any population level. One has to either remove their nests altogether, which basically removes their personal living place, or check for eggs regularly once a week (the gestation period is 13 days, so even a one-week neglect can lead to births). Eggs can be replaced with false plastic eggs, and this prevents females from laying too many. If they do lay too many, they will die from mineral loss. Since these birds do not tame well, removing eggs can be an unpleasant process of repeatedly invading their personal space.
Overall, it is unfortunate that zebra finches are inexpensive birds due to their high level of breeding. They require considerable care to live happy lives. The best care-takers are true avian fanciers — people who have appropriate space for the nests and enough time to allow them to nest-build and breed without over-breeding.
What is the passage mainly about?
| A．Zebra finches over-breed by nature and its consequent ill effects. |
| B．Only people who love birds can take care of Zebra finches. |
| C．Domestic zebra finches require a lot of care to live happy lives. |
| D．Zebra finches never become completely tame. |
By saying “They are the rabbits of the domestic bird world”, the writer means that both rabbits and Zebra finches ______.
| A．have good ability to breed | B．are difficult to be raised |
| C．live delightful lives | D．share responsibilities |
In paragraph 3, the word “gestation” probably means ______.
| A．the period when eggs remain fresh |
| B．the time when finches build up their nest and lay eggs |
| C．the time required for the parents to create a nest |
| D．the time required for baby birds to develop and to be born |
According to the passage, attributes of domestic zebra finches include ______.
| A．their rareness and easiness to be tamed |
| B．their nest-building, sharing of responsibilities and delightful personalities |
| C．their in-breeding, which does not cause as much genetic harm as in other species |
| D．the fact that they are from Australia and have difficulty in adapting themselves |
