From good reading we．can get pleasure, companionship, experience, and instruction．A good book may absorb our attention so completely that for the time being we forget our surroundings and even our identity．Reading good books is one of the greatest pleasures in life．It increases our contentment when we are cheerful, and lessens our troubles when we are sad．Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction．
With a good book in our hands we need never be lonely．Whether the characters portrayed are taken from real life or are purely imaginary, they may become our companions and friends．In the pages of books we can walk with the wise and the good of all lands and all times．The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances．Our human friends sometimes may bore us, but the friends we make in books need never weary us with their company．By turning the page we can dismiss them without any fear of hurting their feelings．When human friends desert us, good books are always ready to give us friendship, sympathy, and encouragement．
One of the most valuable gifts bestowed by books is experience．Few of us can travel far from home or have a wide range of experiences, but all of us can lead varied lives through the pages of books．Whether we wish to escape from the seemingly dull realities of everyday life or whether we long to visit some far-off place, a book will help us when nothing else can．To travel by book we need no bank account to pay our way; no airship or ocean liner or stream-lined train to transport us; no passport to enter me land of our heart's desire．
Through books we may get the thrill of risky adventure without danger．We can climb lofty mountains, brave the danger of an Antarctic winter, or cross the hot sands of the desert, all without hardship．In books we may visit the studios of Hollywood; we may walk among the gay crowds of the Paris wide streets; we may join the picturesque peasants in an Alpine village or the kindly natives on a South Sea island．Indeed, through books the whole world is ours for the asking．The possibilities of our literary experiences are almost unlimited．The beauties of nature, the enjoyment of music, the treasures of art, the triumphs of architecture, the miracles of engineering, are all open to the wonder and enjoyment of those who read．

Motherhood may make women smarter and may help prevent dementia（痴呆） in old age by bathing the brain in protective hormones（荷尔蒙） , U．S．researchers reported on Thursday．
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s（早老痴呆症）．University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans．“Our research shows that the hormones of pregnancy（怀孕） are protecting the brain, including estrogen（雌激素）, which we know has many neuroprotective（保护神经的） effects,” Kinsley said．
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview．“They go through pregnancy and hormonal changes．” Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline．
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida．
“They do not realize that hormones are washing on the brain．If you look at female animals that have never gone through pregnancy, they act differently toward young．But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations（改变） to the brain．”How do scientists know “Motherhood may make women smarter”?
| A．Some researchers have told them． |
| B．Many women say so． |
| C．They know it by experimenting on rats． |
| D．They know it through their own experience． |

How could we possibly think that keeping animals in cages in unnatural environments－mostly for entertainment purposes－is fair and respectful?
Zoo officials say they are concerned about animals．How ever, most zoos remain “collections” of interesting “things” rather than protective habitats （栖息地）．Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural bones．
Zoos claim （声称） to educate people and save endangered species（物种）, but visitors leave zoos without having learned anything meaningful about the animals’ natural behavior, intelligence, or beauty．Zoos keep animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range（分布区）．The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs．
The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise．These results in unusual and self-destructive behavior called zoophobia．A worldwide study of zoos found that zoophobia is common among animals kept in small spaces or cages．Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain．
Furthermore, most animals in zoos are not endangered．Captive breeding（圈养繁殖）of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild．Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out．In fact, baby animals also attract a lot of paying customers．Haven’t we seen enough competitions to name baby animals?
Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them．Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats．How would the author describe the animals’ life in zoos?
| A．Dangerous． | B．Unhappy． | C．Natural． | D．Easy． |
In the state of zoophobia, animals _________．
| A．remain in cages | B．behave strangely |
| C．attack other animals | D．enjoy moving around |
What does the author try to argue in the passage?
| A．Zoos are not worth the public support． |
| B．Zoos fail in their attempt to save animals． |
| C．Zoos should treat animals as human beings． |
| D．Zoos use animals as a means of entertainment． |
The author tries to persuade readers to accept his argument mainly by _____．
| A．pointing out the faults in what zoos do |
| B．using evidence he has collected at zoos |
| C．questioning the way animals is protected |
| D．discussing the advantages of natural habitats |
Although he argues against zoos, the author would still agree that _______．
| A．zoos have to keep animals in small cages |
| B．most animals in zoos are endangered species |
| C．some endangered animals are reproduced in zoos |
| D．it’s acceptable to keep animals away from their habitats |
A year ago August, Dave Fuss lost his job driving a truck for a small company in west Michigan．His wife, Gerrie, was still working in the local school cafeteria, but work for Dave was scarce, and the price of everything was rising．The Fusses were at risk of joining the millions of Americans who have lost their homes in recent years．Then Dave and Gerrie received a timely gift—＄7,000，a legacy （遗产） form their neighbors Ish and Arlene Hatch, who died in an accident ．“It really made a difference when we were going under financially．” says Dave．
But the Fusses weren’t the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches．Dozens of other families were touched by the Hatches’ generosity．In some cases, it was a few thousand dollars ; in other, it was more than ＄100,000．
It surprised nearly everyone that the Hatches had so much money, more than ＄3 million—they were an elderly couple who lived in an old house on what was left of the family farm ．
Children of the Great Depression, Ish and Arlene were known for their habit of saving．They thrived on（喜欢）comparison shopping and would routinely go from store to store, checking prices before making a new purchase ．
Through the years, the Hatches paid for local children to attend summer camp when their parents couldn’t afford it．“Ish and Arlene never asked whether you needed anything,” says their friend Sand Van Weelden, “They could see things they could do to make you happier, and they would do them．
Even more extraordinary was that the Hatches had their farmland distributed．It was the Hatches’ wish that their legacy—a legacy of kindness as much as one of dollars and cents —should enrich the whole community and Ish and Arlene Hatch’s story．
Neighbors helping neighbors ——that was Ish and Arlene Hatch’s story．According go the text, the Fusses_______________．
| A．were employed by a truck company |

| B．The summer camp was attractive to the parents． |
| C．Sandy Van Weelden got a legacy form the Hatches． |
| D．The Hatches would like the neighbors to follow their example． |
The hole in the earth's protective ozone layer（臭氧层）won't repair itself until about two decades later than had been expected, scientists announced.
The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation（紫外线辐射）, helping to make life on Earth possible. For many dacades, ozone was depleted（削减） by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.
Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere（平流层）over the past 27 years.
The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.
Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate（估计）ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.
Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.According to the passage, the ozone layer _______
| A．absorbs as much as sunlight as possible |
| B．protects man against ultraviolet radiation |
| C．controls the changes in temperature |
| D．prevents the production of carbon dioxide |
The improved computer model is believable because _________
| A．it was once proved by facts |
| B．it has been studied for 27 years |
| C．it was created by many scientists |
| D．it is related to satellites and airplanes |
The underlined word “they” in the fifth paragraph refers to ________
| A．the levels of ozone |
| B．ozone-depleting gases |
| C．the ozone holes |
| D．the areas far from the poles |
