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(腸胃氣脹)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(放養(yǎng)的)animal,”said Peter Ampt of the University of New South Wales’s institute of environmental studies.
小題1:The passage mainly talks about ________.
A.a(chǎn) better way to prevent air pollution
B.the danger of methane from farm animals
C.possible solutions to protecting environment
D.a(chǎn) recent research on global warming

A.to reduce the number of animals raised on farms
B.to eat more kangaroos rather than keep more sheep and cattle
C.to eat more plants rather than beef and mutton
D.to grow more trees to absorb carbon dioxide
小題4:From the passage we learn that ________.
A.it is easy to transfer the bacteria to cattle and sheep
B.farm animals are to blame for global warming in some countries
C.cattle and sheep produce more methane than kangaroos
D.less cattle and sheep are raised in New Zealand

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(食肉動物)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
小題1:Comparcd with most carnivores. the olinguito may seem more _____.
A.terrbleB.fierceC.cleverD.lovely
小題2:The onlinguito was unknown to people in the past because ____
A.it was mistaken for another species
B.it was active in the eveing

小題3:What does the underlined word "That" in Paragraph 3 refer to?
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.
小題4:We can infer from the text that ______.
A.the olinguito could be made full use of
B.the number of olinguitos is in the conutrol
C.the clinguito is a completely new species up to now
D.people know more and more about animals

Many parents have learned the hard way that what sounds like open communication is otfen the very thing that closes a youngster’s ears and mouth, One common mistake is the Lecture, the long monologue that often starts with “When I was your age……”Eighteen –year –old Kelly calls lectures “Long , one-side discussions in which I don’t say much.”
Kids reflexively(條件反射地)shout down in the face of a lecture , Their eyes glaze over(呆滯),and they don’t register any incoming information , Listen to 13-year –old Sarah describe her least favorite times with her mom and dad, “First, they scream, Then comes the“We’re so disappointed’ speech , Then the ‘I never did that to my parents’ lecture begins , After that, even if they realize how ridiculous they sound, they never take it back’”.
Lines like “When you have children of your own, you’ll understand” have been seriously said by parents since time immemorial, But many of our expert parents, like Bobby , a registered nurse and mother of three, feel that by falling back on cliches(陳詞濫調(diào))to justify our actions, we weaken our position.
Since kids are creatures of here and now, the far-off future has no relevance to them, Therefore ,good communicators like Bobby suggest, “Give specific reasons for your actions in present language:‘I’m not letting you go to the party because I don’t think there will be enough adult supervisions(監(jiān)護)”。
Betty, who lives in Missouri ,uses and indirect approach, “I find that warnings are accepted more readily if I discuss a news article on a subject I am concerned about, My husband and I talk about it while our children absorb the information, Then they never think I’m preaching(布道)”.
This really helped when Betty’s kids began driving , Instead of constantly repeating “Don’t drink; don’t speed”, She would talk about articles in the paper and express sympathy for the victims of a car crash, Betty made no special effort to draw her kids into the conversation, She depended on a teenager’s strong desire to put in his opinions—especially if he thinks he isn’t being asked for them.
小題1:The purpose of the passage is to       
A.compare two ways of parents’ communicating with their kids
B.give parents advice on how to communicate with their kids
C.explain why kids won’t listen to their parents
D.introduce kids’ reaction to the communication between them and their parents

How to Tell If Someone Is Happy or Sad on the Phone
Scientists have come up with some researches on what makes different types of people“tick”.
The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad.
Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions—it will also use a GPS tracking system to log where the call is made.
 And they’ve already made some pretty major breakthroughs into really getting under the skin of us humans.
The results from the pilot scheme make interesting scientific reading. Among the key revelations (﹦facts) are that callers feel happier at home and sadder at work.
To break it down, scientifically, it shows 45 percent of all emotions produced at home are “happy”and 54 percent of emotions at work are “sad”.
Meanwhile, people show more “intense”(﹦nervous) emotions in the evening than they do in the morning.
Of course, this could just be because most people feel too tired in the morning to get overly “intense”. Eating breakfast and getting to work on time is usually enough of an achievement.
Anyway, the Emotion Sense technology has been developed by psychologists(心理學家) and computer scientists who say it uses speech recognition software and phone sensors(傳感器) attached to standard smart phones to judge how callers’ emotions are changed by everyday factors.
The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral-—boredom or passivity(消極) would fit into this last category.
小題1:How many emotions can the sensors tell?
A.TwoB.ThreeC.FourD.Five
小題2:What does the underlined sentence mean?
A.Scientists have put something testing people’s emotions under humans’ skin.
B.There were some breakthroughs in this technology in getting something from people’s skin.
C.In this technology, people’s skin was broken through.
D.There were improvements in testing people’s emotions.
小題3:Why do most people feel less intense in the morning than in the evening?
A.Because morning is the start of a new day.
B.because they feel too tired in the morning.
C.Because of humans’ physiological structure.
D.Because of the fresh air and bright sunlight.
小題4:Which of the following hasn’t been put into the standard mobile phones?
A.Speech recognition software.B.Phone sensors.
C.GPS sensors.D.Translation system.

Shopping green can make an important contribution to protecting the planet and conserving its resources.
Today’s consumer faces a wider range of choices than ever before, Add to that the steady stream of sales campaigns, and shopping smart only gets harder. To buy economically and reduce waste, safeguard health and protect the environment, you’ll need to follow some basic principles and have a clear idea of what you want.
1. Do Your Homework
Before making any major purchase, take the time to research it. Plentiful resources are usually available online. Avoid buying in a hurry, and don’t be persuaded by overenthusiastic salespeople. Sleep on it if necessary—you won’t regret giving yourself some extra time to think.
2. Take the Long View
Consider the running costs as well as the initial price of any item you buy. Many environmentally friendly products cost more to buy, but save you money in the long run. Choose items that are made to last. For example, pick a sofa that has a hardwood or steel frame rather than one made of softwood, which may break easily.
3. Skip the Disposable Option
Buy reusable products like washable cloth towels, handkerchiefs, serviettes(餐巾)and cleaning cloths rather than paper, single-use varieties. Avoid other disposable supplies like cups, glasses, and chopsticks, too.
4. Take the Local Route
Buy local products that are in season. It’s usually cheaper and fresher and has less harm to the environment. Markets and roadside stands are good sources. Some supermarkets also buy from local producers. Support it if you have one.
5. Avoid Wasteful Packaging
Better not buy products that have too much packaging. It’s estimated that approximately 10 percent of every shopping bill is actually paying for packaging—which you normally just throw away! Moreover, significant amounts of energy are used in the production of packaging. Purchasing refillable and renewable containers can also help cut this kind of waste.
小題1:What could be the best title for this passage?
A.Protection of the Planet
B.Green Shopping Principles
C.Environmentally Friendly Products
D.Resource Conservation
小題2:The underlined phrase “sleep on it” has the similar meaning with      .
A.think it overB.forget about it
C.set it asideD.put it into action
小題3:Why does the author advise us to buy lasting products?
A.Because they are less expensive to buy.
B.Because they save money in the long run.
C.Because they will never break.
D.Because they are local products.
小題4:Which of the following can be considered green shopping?
A.Following the stream of sales campaigns.
B.Buying disposable chopsticks.
C.Focusing on packaging.
D.Purchasing from local markets.

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.
As your eyes move along the line of print, they make fixations(固定) or pauses. It is important that you see several words at a fixation. It is also important that your eyes leave a group of words quickly and move on to another group. The number of letters or words that you see at a fixation is called your eye span. Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.
The way in which you read always depends on what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method that is necessary. Here are four ways of reading:
(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.
(2) Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.
(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive(精深的) study of your school subjects, solving maths problems or reading directions.
(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing material that you already know well.
小題1:The main reason for reading fast is that you can           what you are fast reading.
A.get the ideasB.save timeC.understand betterD.learn well
小題2:The way of reading always depends on           .
A.the method that you likeB.your reading material
C.your reading purposeD.both B and C
小題3:The underlined word “skimming” in the fourth paragraph means              .
A.reading very fast
B.looking carefully
C.reading only the main points
D.reading some parts of the material
小題4:Careful reading is an important kind of reading              .
A.when you read a story for enjoyment
B.when you go over a lesson that you have already known well
C.when you read the directions before using a camera which is expensive
D.when you wish to find a lost place that you have read

The ozone layer(臭氧層) is a thin layer of gas around the earth. It forms a special “blanket” around the planet. This “blanket” protects the earth from dangerous rays produced by the sun. Without the ozone layer, the earth’s climate could warm to dangerous levels. This increase in temperature would threaten our survival. Scientists recently have discovered a hole in the ozone layer above the Antarctica. Now there is great concern that this warning has started, endangering all life on the earth.
What has destroyed part of the ozone layer? Scientists do not know for sure. They suspect that our popular spray cans (噴漆罐) have played a part in the damage. Many spray cans contain dangerous gases. These gases might have destroyed the ozone layer fifteen miles above the earth’s surface, The chemicals used in refrigerators (冰箱) and air conditioners may contribute to the problem, too.
Many scientists believe that the destruction of the ozone layer is a serious problem for people everywhere. Global warming could change weather patterns around the world. Farmers and ranchers(牧場主) could find it more and more difficult to produce enough food for the earth’s people. If more of the sun’s dangerous rays reached the earth, there also could be an increase in skin cancers. Some skin cancers might cause people to die. Although some scientists do not believe there is a serious danger, obviously no one wants to take any chance on such a possibility.
Can scientists repair the hole in the ozone layer? They really don’t know the answer to that question. Can people do anything to save the ozone layer that the earth still has? Scientists stress the need to limit the use of spray cans and other items that contain the dangerous gases. This will not be an easy task. People all over the world use these items. Solving the problem certainly will require commitment and cooperation from everyone.
小題1:The ozone layer exists to _____.
A.warm the earth to a proper level for life
B.protect the earth from dangerous sun rays
C.make all life on the earth in a dangerous situation
D.prevent human beings from being harmed from the earth
小題2:Which of the following statements is TRUE according to the passage?
A.Scientists aren’t sure what has destroyed part of the ozone layer.
B.Scientists recently have discovered a hole in the Antarctica.
C.Scientists prove that spray cans have destroyed part of the ozone layer.
D.Global warming doesn’t affect weather patterns around the world.
小題3: The following may do harm to the ozone layer EXCEPT ______.
A.spray cansB.refrigeratorsC.ranchersD.a(chǎn)ir conditioners
小題4: Saving the ozone layer needs everyone’s effort because _____.
A.scientists are badly in need of others’ help
B.items containing dangerous gases should be forbidden
C.scientists can’t afford so much money to take measures
D.people all over the world use items containing dangerous gases

What do college teachers think of high school English teachers’English teaching? And how should we see it? Let’s read the following.
A teacher from a community college addressed a sympathetic audience. Heads nodded in agreement when he said, “High school English teachers are not doing their jobs.” He described how weak his students were—all high school graduates who can use language only at a Grade 9 level.
My topic is not standards nor its decline(降低). What the speaker was really saying is that he is no longer young; he has been teaching for sixteen years, and is able to think and speak like a mature adult.
My point is that the frequent complaint of one generation about the one immediately following is natural. It is also human nature to look for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies(缺陷). But since then, English teachers have been under constant attack.
The complainers think they have hit upon an original idea. As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults, the language of the young always seems inadequate.
Since this concern about the decline and fall of the English language is not seen as a generational phenomenon but rather as something new and peculiar(特有的) to today’s young people, it naturally follows that today’s English teachers cannot be doing their jobs.
小題1:The speaker believed that ________.
A.he was an excellent language teacher because he had been teaching English for sixteen years
B.the younger generation was as likely as not worse at language than the older generation
C.high school English teachers should be responsible for their students’ poor command of English
D.The fact that the students didn’t work hard enough contributed to their poor command of English
小題2: In the author’s opinion, the speaker ________.
A.had exaggerated (夸大) the language problems of the students
B.was right in saying English teachers were not doing their jobs
C.gave a correct judgment of the English level of the students
D.thought and spoke in a wise and responsible way
小題3:What can we conclude from the passage?
A.Language learning and improving needs time and effort.
B.The author disagrees with the speaker over the standard of English at Grade 9 level.
C.It is reasonable to include English as one of the high school subjects.
D.The English language teaching is by no means an easy job for college teachers.
小題4:The author’s attitude towards the speaker’s remarks is ________.
A.neutral(中立的)B.critical
C.positiveD.compromising(妥協(xié)的)

It is true that people with better education are usually able to get better paying jobs. In other words, they have more chances to choose a good job while people with little or no education don’t. It seems that the purpose of education is to make people get jobs. But this isn’t accepted by all people.
Some people may think that a person should spend the best years of his life to get education only for a way of living. This was probably one of the earliest reasons of education. In fact, if education is just a way of making a living, people don’t need to spend so much time in school. People can get education for a living in a short time. Subjects like history and geography need not be taught to everyone. Even language and mathematics need not be taught in detail(詳細地), either. Here it is clear that education is much more than teaching a man to get a way of living.
Education is well-rounded and it is mainly for improving a man. It is not only to teach him to speak, read and write, but also to develop his creative thinking and other abilities. After that, it is to make him a wise man and thankfully enjoy the achievements of human. Education is to make a man lead a better life. Educated people are expected to be able to listen to good music, read good books, watch plays and most of them take an interest in the world.
I would agree that making a good living is an important reason for education, but certainly not the most important or the main reason.
小題1:People with little education usually ____.
A.spend a long time in school
B.have a good chance to get a job
C.spend the best years to choose jobs
D.have fewer chances to get a good job
小題2:The earliest education was probably to ______.
A.make a man lead a better life
B.teach a man to write and think
C.make people get a way of living
D.teach people to read good books
小題3:It is expected that educated people will be able to _____.
A.a(chǎn)ccept education as a way of living
B.take an interest in the whole world
C.develop their abilities to make plays
D.learn subjects like language and math
