When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very      . Some stories are told       they were true. Real people who live in a       world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not       . They are characters and creatures that are very different from us and do things that would be       for us.

But there is more to books and writing than this. If we think about it, even realistic writing is only     . How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we       seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than      . Reading, like writing, is an action. It is a way of      . When we read or write something, we do much more than simple look at words on a page. We use our       -- which is real-- and our imagination-- which is real in a different way --- to make the words come to life in our minds.

　　Both realism and fantasy(幻想)       the imagination and the “magic” of reading and writing to make us think. When we read       realistic, we have to imagine that the people we are reading about are just like us, even though we       that we are real and they are     . It sounds       , but it works. When we read, we fill in missing information and     about the causes and effects of what a character does. We help the writer by       that what we read is like real life. In a way, we are writing the book, too.

　　Most of us probably don’t think about what is going on in our       when we are reading. We pick up a book and lose       in a good story, eager to find out what will happen next. Knowing how we feel       we read can help us become better readers, and it will help us discover more about the real magic of books.

　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
　　　A.mainly because the levels of carbon dioxide are rising
　　　B.partly due to variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.On the basis of their models,scientists are of the opinion that ________.
　　　A.the climate of the world should be becoming cooler
　　　B.the new Ice Age will be delayed by the greenhouse effect
　　　C.the man - made warming effect helps to increase the solar effects
　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

Honey(蜂蜜)from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest(巢)and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper一a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax (蜂蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees’ nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
【小题1】Why is it difficult to find a wild bees' nest?

Haisong Jiang, who slipped (偷偷溜进) past a security checkpoint(安全关卡) on Jan. 3, causing a shutdown of Newark Airport, tried to apologize for his mistake.
" I feel guilty about this serious mistake. At that moment, I was very excited with my girlfriend, and I didn't think too much," Mr. Jiang, 28, said Tuesday in his first interview since causing the six-hour shutdown at the airport.
On Tuesday, Newark Municipal Court judged that besides the community service, he must pay a $500 fine (罚金) and $158 in court fees. In an agreement between the court and Mr. Jiang's lawyer, Mr. Jiang will pay off his money punishment all by community service instead.
　　Haisong Jiang, a native of China, about a year ago moved to the United States in 2004 to study and met his girlfriend, also Chinese and 26. She has since moved to California.
The lovebirds did the town over the Christmas holidays: shopping in SoHo, visiting the tree at Rockefeller Center, celebrating New Year's Eve in Times Square - the works. On Jan. 3, he watched her pass through security, but he wanted to spend more time with her. When he noticed the officer leave his post, he saw his chance, he said. He slipped under the rope and kissed her and, arm in arm, walked her to her Continental Airlines gate and saw her onto the jetway. "And immediately I left," he said.
　　Three days passed. "Friday, the police found me," the future scientist said. He was at the gym when his roommate called to say two police officers were at their home. "It's not right to enter the airport. Immediately I know the police want to ask me this thing."
　  He expects to serve half of his community service in a soup kitchen - "I like to cook" - and the other half in a hospital. He plans on moving to California to be with her and work in a laboratory after completing his degree in May or June.
He never types his name into search engines on the Net: the number of hits is shocking.
What’s the best title of the passage?
A. A moving love story  B. An escape from security check
