The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can't stay under the water's surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double up in pain. They can even kill him.
【小题1】On the whole, this passage is about ________.
| A．special mixtures of gases in deep sea |
| B．the problems man faces in deep sea diving |
| C．air pressure under the surface of sea water |
| D．a kind of illness that man suffers in the sea |
| A．deep divers should be in good health |
| B．divers explore the deep sea only for treasure |
| C．diving under the water too quickly causes a kind of illness |
| D．there is a special mixture of gases under the sea |
| A．the sea began to interest man a few years ago |
| B．man is not at home deep in the sea |
| C．all divers will get the bends sooner or later |
| D．the air in the sea water will kill a diver if he is not careful |

解析试题分析：文章介绍了人类从很早就探索海洋，从中获取吃的，矿物质，财富等等，但是很长时间以来，他们只可以航海，但是没办法去海洋的下面去，潜水员要去水面以下，就必须带氧气瓶，并且水的压力是很大的，如果下去以后在回来时速度太快，就会有身体上的不适等。
【小题1】 B大意理解题。文章的第二自然段人不能在水面以下呆的时间太长，如果去探索深海，会面临更大的危险。第二自然段讲了潜水员去水下的时候要带氧气瓶，水的重量是空气重量的800倍，因此要承担很大的压力。第三自然段是潜水员去水深处时，他的血液会吸收他呼吸的气体，急速反回时，会有更大的危险。故答案应为B。
【小题2】A细节理解题。文章的第三自然段讲述了潜水员要承认很大的压力，血液会吸收他呼吸的气体，如果返回太快，血液里的气体会形成气泡，就会患上减压病，会承受痛苦，甚至有生命危险，由此可知，运动员身体必须健康。故答案应为Ａ．
【小题3】B细节判断题。Ａ人类在许多年前就开始探索大海，而第一自然段人类探索大海数千年了，故Ａ是错误的；all divers will get the bends sooner or later所有的潜水员都迟早会患减压病的，这在文章当中是无法反映出的；文章的最后一自然段最后一句话是说减压病可能会使一个人丧生，不是海水中的空气，是错误的，故Ｂ是正解的，人类在深海是不可能安家的。

How long do you want to live? How many years might be added to a life? Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.（寿命）
“I think we are knocking at the door of immortality(永生) , " said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that's a conservative estimate(保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.
However, many scientists who research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120,you know, could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

| C．they believe that there is no limit of living |
| D．they are able to make people live past the present life span |
| A．people can live from 120 to 180 |
| B．it is possible for humans to live longer in the future |
| C．the human body is designed to last past about 120 years |
| D．it is still doubtful how long humans can live |
| A．using genes as well as nanotechnology |
| B．the idea of living beyond the present life span |
| C．a great push |
| D．the conservative estimate |

The olinguito（小尖吻浣熊）is new to science. Although lt has been living in the cloud forests of South Amcrica for some time.
Scientists say the olinguito is the first new carnivore（食肉动物）discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now.
Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo(尖吻浣熊). Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed
【小题1】Comparcd with most carnivores. the olinguito may seem more _____.
| A．terrble | B．fierce | C．clever | D．lovely |
| A．it was mistaken for another species |
| B．it was active in the eveing |
| C．it was too small to be seen clearly |
| D．it covered itself by its long tail |
| A．Having been studying olingos for ten years. |
| B．The short video the animal expert made. |
| C．His communication with an expert in Ecuador. |
| D．Differences between olingos and olinguitos. |
| A．the olinguito could be made full use of |
| B．the number of olinguitos is in the conutrol |

A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.
By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation(诱惑) early were more likely to be lonely, easily frustrated and inflexible(顽固的)．
Actually, the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test.
The hardware of the brain and the software of the mind have long been scientists' concerns. But brain theory can't explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul.
Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people's success, brain ability measured by IQ may actually matter less than the qualities of mind once thought of as “character”．
EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one's ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients (要素) for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from social class to luck.
While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.
【小题1】The experiment with the four-year-olds makes it clear that ________.
| A．the age of 4 is a proper time for scientific experiment |
| B．emotional intelligence won't show up until adolescence |
| C．the ability of self-control plays a role in personal success |
| D．candy can be used to measure a person's emotional intelligence |
| A．There is no link between EQ and IQ. |
| B．The higher a person's IQ is, the higher his or her EQ is. |
| C．Some people can be blessed with lots of both, but some with little of either. |
| D．Scientists are trying to discover the way in which EQ and IQ work together. |
| A．kind | B．floating | C．excited | D．optimistic |
| A．To amuse both the children and readers. |
| B．To prove the scientist’s wisdom. |
| C．To introduce the topic of the text. |
| D．To show us how to do an IQ test. |
| A．Information about famous people with high EQ. |
| B．Examples showing the opposite voice about EQ. |
| C．Some reasons why EQ is relatively new field. |
| D．Strong demands for basic emotional education. |

Recently a Beijing father sent in a question at an Internet forum(论坛) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行话) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
【小题1】By writing the article, the writer tries to .
| A．explain some Internet language |
| B．suggest common Internet language |
| C．laugh at the Beijing father |
| D．draw our attention to Internet language |
| A．Fathers can’t possibly know it. |
| B．The daughter should understand it. |
| C．Online game players may know it. |
| D．“Super Girl” shouldn’t have used it. |
| A．are used not only online |
| B．can be understood very well |
| C．are welcomed by all the people |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out，which is thought to be responsible for global warming．
Thanks to special bacteria in the stomachs，kangaroo flatulence（肠胃气胀）contains no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep which produce large quantities of the harmful gas．
While the usual image of greenhouse gas pollution is a huge factory chimney pushing out carbon dioxide，farm animals’ passing wind contributes to a surprisingly high percentage of total emission（排放物）in some countries．
“Fourteen percent of emissions from all sources in Australia is from methane from cattle and sheep，’’said Athol Klieve，a senior research scientist with the Queensland state government．
“And if you look at another country such as New Zealand，which has got a much higher agricultural base，they are actually up around 50 percent，”he said．
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers．
But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep．
Another group of scientists，meanwhile，has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos．And about twenty percent of health-conscious Australians are believed to eat the national symbol already．
“It’s low in fat，it’s got high protein levels and it’s very clean in the sense that basically it’s the free-range（放养的）animal，”said Peter Ampt of the University of New South Wales’s institute of environmental studies．
【小题1】The passage mainly talks about ________.
| A．a better way to prevent air pollution |
| B．the danger of methane from farm animals |
| C．possible solutions to protecting environment |

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either ．
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind ．If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping （feeling of cold, a noise, a discomfort, etc．） and it may also use your past experiences and the wishes and the interests you have now．This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom．
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment．A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton．He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean．Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem．They believe that dreams are mostly expressions of wishes that do not come true．In other words, dreams are a way of having your wishes carried out．
【小题1】From the passage we know that our dreams ___________.
| A．are imagination of our daily life |
| B．are man’s curious look into the future |
| C．have nothing to do with our feelings |
| D．are to some degree connected with our feelings |
| A．they are interested in exams |
| B．they are often worried about their studies |
| C．they hope for a better life |
| D．they show much interest in their studies |
| A．is considered interesting , but unreasonable |
| B．gives a good answer to the question why we dream |
| C．has some value , though not fully convincing |
| D．has been proved by the findings of their studies |
| A．Why People Dream ? | B．New Findings about Dreams |
| C．Dream Makes Hopes | D．What Dreams Mean ? |

Thanks to special bacteria in their stomachs, kangaroo flatulence(肠胃气胀)contains no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.
