A new study finds that the animal known as man’s best friend can also be a good friend to the heart. Researchers in California say they have found that even just a short visit with a dog helped ease the worries of heart patients.               
The study divided the patients into three groups. In Group A, a dog and a person visited each patient for twelve minutes. Patients in Group B received just a human visitor for twelve minutes. And members of Group C received no visitor, human or canine(犬的).
The dogs would lie on the hospital bed so the heart patients could touch them. The researchers say some patients immediately smiled and talked to the dog and the human visitor. Dogs, in her words, “make people happier, calmer and feel more loved.”
The researchers examined the patients before, during and after the visits. They measured stress levels based on blood flow and heart activity. They say they found a twenty-four percent decrease in the group visited by both a dog and a person. They reported a ten percent decrease in the group visited by a person only. There was no change in the patients without any visit. These patients, however, did have an increase in their production of the hormone epinephrine (epinephrine腎上腺素). The body produces epinephrine during times of stress.
The increase was an average of seven percent. But the study found that patients who spent time with a dog had a seventeen percent drop in their levels of epinephrine. Patients visited by a human but not a dog also had a decrease, but only two percent.
小題1:The author believes that _______.  
A.the dog can take the place of most medicines
B.the dog is the most popular pet for man
C.the findings of the research cannot be trusted
D.visits by a human work better than visits by a dog
小題2:Which of the following best shows the stress level changes in the groups of patients? BACC

小題3:From the research findings we may conclude that _______.
A.the less the body produces epinephrine, the better
B.the longer a visit lasts, the happier the patient should be
C.the patients enjoyed the dogs’ company more than the human visitors’
D.it’s impossible for heart patients to recover without dogs’ visits
小題4:Which of the following is the best title for the passage?
A.Worried Heart PatientsB.Epinephrine and Stress
C.Good Friend to the HeartD.Three Groups of Patients

小題1:B
小題2:A
小題3:C
小題4:C

小題1:推理判斷題。本題要求根據(jù)作者的遣詞用句和表述方式判斷其情感態(tài)度,這是對
較高層次的閱讀能力的考查。A選項有些言過其實: 作者雖認(rèn)同狗在病人康復(fù)過程中的
積極作用,但沒有表明它可以取代藥物;透過全文的字里行間,可以看出作者對該項研
究成果的極大興趣和深度認(rèn)同,故排除C項;仔細(xì)研究第4、5段提供的數(shù)據(jù),可知狗
的探視比人的探視給病人提供的安慰更多,故排除D項;文章首句中known as man’s best

"The world's oceans are slowly getting more acidic,”say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
The lowering of the waters’pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.
Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.
These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed(超過)anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.”
However, it is not absolutely clear what that means for ocean life.Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes.Coral reefs and other organisms whose shells contain calcium carbonate(小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.
In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming.But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.”
小題1:According to Dr Caldeira,__________ .
A.ocean absorption of carbon dioxide is a good thing
B.more oil fuels will be used in the near future
C.scientists may predict climate changes with computer models
D.the future situation of the amount of acidity is extremely serious
小題2:f the water's acidity level keeps rising,_________ .
A.ocean life whose structures contain calcium carbonate may be affected
B.the waters’pH value will become higher and higher
C.organisms living near the surface are more sensitive to pH changes
D.some disastrous events will occur more often than before
小題3:Most experts once believed storing carbon dioxide in the ocean would reduce________ .
A.the CO2 absorbed by the oceanB.the amount of greenhouse warming
C.the acidity of the oceanD.the gradual release of CO2
小題4:The purpose of this passage is to_________ .
A.show people the findings of a research teamB.inform people of how acid the ocean is now
C.introduce Dr Caldeira and his team's researchD.warn people of the higher level of CO2

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平裝本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全書), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
小題1:It can be inferred from the passage that ________.
A.TV programs are a chief provider of knowledge
B.cinemas are the best choice in getting information
C.reading is a cheap way of learning and having fun
D.newspapers are an expensive way to enjoy oneself
小題2:What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?
A.People only need reading, though.B.Reading is still necessary today.
C.Reading is more fun than television.D.Watching television doesn’t help reading.
小題3:What can we learn from the passage?
A.Fewer and fewer people will buy books.
B.A good dictionary should be kept in every home.
C.Books with hard covers sell better than paperbooks.
D.More people like TV programs about famous men.
小題4:What can we learn from the passage?
A.Fewer and fewer people will buy books.
B.A good dictionary should be kept in every home.
C.Books with hard covers sell better than paperbooks.
D.More people like TV programs about famous men.

American schools do not have separate classes for boys and girls. If boys want to cook or to sew, they can learn these things in classes that are no longer just for girls. If girls want to repair cars, they can now learn this in school. Most students like to have boys and girls on the same baseball team.
Many boys and girls dress alike in school. They were blue jeans and sport shirts. Some have long hair and some have short hair. Sometimes a boy has longer hair than a girl.
Even the language is different. Students learn to say fire fighter instead of fireman, police officer instead of policeman, and letter carrier instead of mailman. A person does not need to be a man to fight a fire or to deliver the mail.
Most people think that these changes are good. They give all people an equal chance to be happy and to do what they want to do with their lives. Fathers like to tell their sons that they can grow up to be president. Today, mothers can tell the same things to there daughters.

PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.
The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操縱桿). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.
“It just allows us to do something we’ve not been able to do before,” Stover said, “We needed them yesterday.”
He said snifter dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.  
小題1:Which institution is responsible for the development of Choset’s robots?
A.Robotics Trends.B.Pittsburgh City Council.
C.Carnegie Mellon University.D.Federal Emergency Management Agency.
小題2:Choset believes that his invention ______.
A.can be attached to an electronic arm
B.can be used by hobbyists in model airplanes
C.can find victims more quickly than a snifter dog
D.can sense its way no better than its operators
小題3:By saying “We needed them yesterday” (paragraph 7), Stover means that snake-like robots _____.
A.could help handle the aftermath of Hurricane Katrina
B.would have been put to use in past rescue work
C.helped rescuers search flooded houses yesterday
D.were in greater need yesterday than today
小題4:What is the text mainly about?
A.Snake-like robots used in industries.
B.Snake-like robots made to aid in rescues.
C.The development of snake-like robots.
D.The working principles of snake-like robots.

Everyday rubbish could provide a valuable source of energy thanks to a clever new invention. Smelly methane(沼氣)gas expelled from landfill sites containing tones of rotting household waste could be used to produce a valuable energy resource. In Europe alone land fill tips produce 94 billion cubic meters of methane per year but currently only one percent of what could be a valuable source of energy is used, the rest is burnt off to prevent an explosive build up of gas.
Methane gas forms when organic matter breaks down and is drawn off from large rubbish tips by pipes sunk into the middle of the waste. Until now this process wasn’t possible on small sites because the pipe allowed oxygen to seep in and that stop the breakdown process.
Viktor Popov of the Wessex Institute of Technology has now developed a system to modify existing landfill sites by making them airtight while the methane is extracted from sunken wells. The site is covered by a special three-layered skin whose two outer layers are made of clay with a pressurized(加壓的)layer of carbon dioxide gas in the middle. As the methane is sucked out through a central well it is replaced by carbon dioxide from the middle layer rather than oxygen, allowing the breakdown process to continue.
Unfortunately there are no plans to use the power of methane even though Popov claims his invention could provide a valuable source of energy over the next 20 years.
小題1:The passage mainly introduces ______ to us.
A.how to make methaneB.a(chǎn) new way to make use of rubbish
C.the valuable things in rubbishD.the amount of rubbish beig reused
小題2:From the passage we can see that _____.
A.in Europe 94 billion cubic meters of methane is produced every year
B.some of the waste will explode if it is not burnt off
C.99% of the rubbish has been burnt off in Europe
D.only a very small part of this kind of energy is used in Europe
小題3:In the passage the underlined word “that” refers to ______.
A.methane gasB.the long pipeC.oxygenD.the rubbish
小題4:Which of the following statement is NOT true according to the passage?
A.Oxygen can cause the breakdown process to stop.
B.When the methane is sucked out, oxygen will enter from the middle layer.
C.Carbon dioxide doesn’t affect the breakdown process.
D.The new invention has not been put into use.

Australians have been warned they face a life or death decision over their water — drink recycled sewage (污水) or die.
With t he drought (干旱) continuing, the country is set to be forced to use purified (凈化的) waste water for drinking, even though there is great opposition to the measure.
Queensland has become the first state to introduce the policy after a warning from its premier .
"I think in the end, because of the drought, all of Australia is going to end up drinking recycled purified water," said Peter Beattie.  
"These are difficult decisions, but you either drink water or you die. There's no choice. It's liquid gold, it's a matter of life and death."
Beattie said Australia's second largest state would become the first to use recycled water for drinking.
Water is recycled in Britain and parts of northern Europe along with the US and Israel.
But Australians have never liked the idea.
To try to change the way Australians think, Prime Minister John Howard and Environment Minister Malcolm Turnbull have adhered to Queensland's move.
"I am very strongly for recycling and Mr. Beattie is right and I agree with him completely," Howard said.
“Australian cities, all now facing water shortages because of the worst drought on record, must start to use recycled water.” added Turnbull, "All of our big cities have to widen the range of water sources to include sources which are not dependent on rainfall."
小題1:What is the text mainly about?
A.Continuing drought forces Australians to drink recycled sewage
B.Australians face the choice of life and death
C.Premier Beattie is worried about his people’s health
D.We should avoid drinking recycled water to keep healthy
小題2:According to the passage, which of the following is TRUE?
A.Nobody disagrees to the idea of drinking recycled purified water
B.Australia's second largest state has become the first state to introduce the policy
C.No other countries but Australia decide to drink recycled water
D.The drought is the worst one in the droughts recorded in Australian history.
小題3:What can we learn from the last paragraph ?
A.Australians have never like drinking purified waste water
B.Australians should develop more water sources to live through the hard time
C.Australians can’t depend upon rainwater , which is not suitable for drinking .
D.Australian government has no ability to solve the problem of water shortage
小題4:The underlined phrase “adhered to” in Paragraph 9 probably means_________.
A.dislikedB.gone againstC.supportedD.doubted
小題5:It can be inferred from what Premier Peter Beattie said that________.
A.he gives orders to drink purified waste water
B.It is painful for him to see his people drink recycled sewage
C.If the decision is made, people won’t survive the drought
D.It’s up to you to either make a life or death decision

The United States is trying to improve an edueation system that produces millions of citizens who cannot read, write, or add—let alone finding their country on a map.
In his first State of Union message since taking office a year ago, President George Bush promised to wipe out illiteracy(文盲) in the next decade and declared that“by the year 2008, U.S students must be first in the world in math and science achievements. ” They have a long way to go. American students were placed 14th in a recent general science test conducted in 16 countries. In a separate survey of chemistry students, the United States came 12 out of 14. In a mathematics test, they were last. According to Bush, there are 17 million illiterates in this country of 245 million people. Other estimates put the number as high as 23 million. In percentage terms, that ranks the United States alongside Niearague and below Cuba. “This nation,”Bush said in his State of the Union address, “will not accept anything but excellent in education.” Bush, who has declared himself “Education president”, and senior officals of his administration are warning that the United States will be unable to compete in the world without an educated workforce.
How to increase educational standards is a matter of debate in a country whose schools have no uniform national curriculum and are subject to a confusing variety of state and local controls. Most experts think that the problem lies at the elementary and high school'levels rather than with universities-but even their graduates show huge gaps in general knowledge. Among the root causes most frequently mentioned in education debates is the low respect in which U.S. society holds teachers-in contrast to Japan and Germany. In Japan teaching is a profession of high prestige(威望) and high pay. In the United States teachers are near the bottom of the society.
5.By“the United States came 12 out of 14”(Para. 2), the author means .      
A.the United States ranked 12th not 14th in the chemistry test
B.the United States ranked 12th in the chemistry test conducted by 14 countries
C.the United States progressed from 14th to 12th in the chemistry test
D.the United States ranked 12th in chemistry test and 14th in general science test
6.The cause of low educational level in America include the following EXCEPT that .      
A.some problems exist in primary and secondary education
B.society keeps teachers in low respect
C.America pays more attention to economy instead of education
D.America has no uniform national courses
7.Which of the following statements can be inferred from the passage?
A.President Bush carried out his promise made in his first State of Union message.
B.The education in Japan and Germany is in higher level.
C.According to Bush, the number of illiterates accounts for 9% of the total.
D.Teachers in the United States enjoy good treatment and great respect.
8.Which of the following is the right order of the least-first of the percent of illiterates?
A.Germany, Cuba, Nicaragua.         B.Germany, Nicaragua, Cuba.
C.Nicaragua, Japan, Cuba.            D.Cuba, Japan, Nicaragua.
