Can dogs and cats live in peace in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight. A recent research has found a new way for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two­thirds of the homes interviewed reported a positive relationship between their cat and dog.
However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while attacking and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals attack, while a dog doing the same signals admitting defeat.
In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “dog”, and dogs can learn how to talk “cat”.
What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other's body signals, suggesting that the two may have more in common than was previously thought. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.
The advantage of this research on cats and dogs may not only about pets — to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances (氣旋) hundreds — even thousands — of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist (潮濕的) air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is switched to energy in the form of strong winds. As the heat increases, the young hurricane begins to turn around in a counter-clockwise motion (反時(shí)針?lè)较?.
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released (釋放) by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, rather than wind, is the main source of death and destroying in a hurricane. A typical hurricane brings 6-to-12-inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea — the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
【小題1】An ordinary tropical storm is called a hurricane when ______.

A.it occurs in the Caribbean seas
B.its winds reach 75 miles per hour
C.it makes its way to the coastline
D.its winds begin to circle on the sea
【小題2】What is the worst thing about hurricane?
A.The rough water. B.The violent winds.
C.The heat it gives out. D.The length of its life.
【小題3】What does the third paragraph mainly talk about?
A.The hurricane is extraordinarily powerful.
B.The hurricane is used to generate electricity.
C.The hurricane can otherwise offer an unusual sight.
D.The hurricane can give people an unforgettable experience.
【小題4】The counter-clockwise movement of the hurricane is caused by ______.
A.the low-pressure area in the center of the storm
B.the force of waves of water
C.the increasing heat
D.the trade winds

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological(生態(tài)的) disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸鹽)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine(帶狀礦). When a company strip-mines, it removes the top layer(層) of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.
【小題1】What might be the author’s purpose in writing the text?

A.To seek help for Nauru’s problems.B.To give a warning to other countries.
C.To show the importance of money.D.To tell a heartbreaking story of a war.
【小題2】What was Nauru like before the Europeans came?
A.Rich and powerful. B.Modern and open.
C.Peaceful and attractive. D.Greedy and aggressive.
【小題3】The ecological disaster in Nauru resulted from           .
A.soil pollutionB.phosphate over mining
C.farming activity D.whale hunting
【小題4】Which of the following was a cause of Nauru’s financial problem?
A.Its leaders misused the money.B.It spent too much repairing the island.
C.Its phosphate mining cost much money.D.It lost millions of dollars in the civil war.
【小題5】What can we learn about Nauru from the last paragraph?
A.The phosphate mines were destroyed.B.The leaders will take the experts’ words seriously.
C.The island was abandoned by the Nauruans.D.The ecological damage is difficult to repair.

A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.
Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.
But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸發(fā)) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.
The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.
In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.
【小題1】Which is the best title of the passage?

A.A Few Degrees can Make a Big Difference for Storage

D.the inspiration of the invention
【小題3】What is it that essentially keeps the food in the container from spoiling?
A.the wet cloth covering the cooling system.
B.the moving drier air outside the container
C.the wet sand between the containers
D.a(chǎn) drop in temperature by evaporation
【小題4】According to the passage, where can we possibly see the invention?
A.rich and advanced families

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
【小題1】What does the underlined phrase “over-consumption” refer to?

A.Using too much packaging. 
B.Recycling too many wastes. 
C.Making more products than necessary. 
D.Having more material than is needed. 
【小題2】The author uses figures in Paragraph 2 to show _______.
A.the tendency of cutting household waste 
B.the increase of packaging recycling 
C.the rapid growth of super markets 
D.the fact of packaging overuse 
【小題3】According to the text, recycling ______.
A.helps control the greenhouse effect 
B.means burning packaging for energy 
C.is the solution to gas shortage 
D.leads to a waste of land 
【小題4】 What can be inferred from Paragraph 4?
A.Unpackaged products are of bad quality. 
B.Supermarkets care more about packaging. 
C.It is improper to judge quality by packaging. 
D.Other products are better packaged than food. 
【小題5】 What can we learn from the last paragraph?
A.Fighting wastefulness is difficult. 
B.Needless material is mostly recycled. 
C.People like collecting recyclable waste. 
D.The author is proud of their consumer culture.

Surfing the Internet for fun will make you a better employee,according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author brent Coker said“Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,”Coker said on the university’s website.”Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself,leading to a higher total Internet attention for a day’s work, and as a result, increase productivity(生產(chǎn)效率),”he said.
   According to the study of 300 workers ,70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.”Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online, ”said Coker.”that’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation(),or were on the Internet for lee than 20 percent of their total time in the office.”Those who spend too much time surfing the Internet will have a lower productivity than those without,”he said.

Food prices have risen sharply over the past few years. The good news is that the rate of increase has slowed. The bad news is that prices will not go down anytime soon.
Also,the rate of global agricultural production is slowing. Yet it needs to increase 60% over the next 40 years to feed a growing world population.
These are among the findings from the OECDFAO(the Organization for Economic Cooperation and Development & the Food and Agriculture Organization)Agricultural Outlook(展望)2012-2021.
FAO Director­General Jose Graziano da Silva spoke at a news conference in Rome when the report was released. Mr.Da Silva said that,not surprisingly,the world's poorest people will feel the greatest effects of higher prices.
“For the millions and millions of extremely poor people, the effects of high food prices are clear—they might have to change their diets,usually to ones with poorer nutrition quality, ”he said.
In middle­income countries, people are gaining weight as they eat fewer fruits and vegetables and more of the cheaper but less nutritious foods.
The report also shows that farmers in poorer countries will be leading efforts to feed an expected 9,000,000,000 people by 2050.The outlook predicts that farmers in Latin America,the Caribbean and sub­Saharan Africa will drive agricultural production in the future.
Angel Gurria,Secretary­General of the OECD,said:“We can feed 9,000,000,000 people by 2050 on this planet. But we have to organize ourselves better.” But there are plenty of challenges.One­fourth of all agricultural land is damaged. Many countries face water shortages(短缺).And experts believe climate change is driving increasingly unusual weather patterns.
The report says farmers need to use more growing methods that can't cause damage to the environment.At the same time,it says governments should end economically harmful supports and spend more money to increase agricultural production.Mr.Gurria says rich and poor nations need to treat agriculture more like a business.
“In many cases,agriculture is related in people's minds to the poorest. It's related to aid. It's related to very poor living conditions,etc. We have got to shake that image away,”he said.
【小題1】Why are people gaining weight in countries with average incomes?

A.They eat more food. B.They eat less nutritious foods. 
C.They eat cheaper fruits. D.They eat cheaper vegetables. 
【小題2】It can be inferred from the text that poorer countries ______.
A.a(chǎn)re damaging a great part of their agricultural land 
B.will play a great role in feeding the growing world population 
C.a(chǎn)re spending lots of money increasing agricultural production 
D.will not be so seriously affected by food prices as rich nations 
【小題3】What can be done to deal with the slow agricultural production?
A.Improving the growing methods. 
B.Finding more agricultural land. 
C.Preventing governments' involvement. 
D.Improving farmers' living conditions. 
【小題4】Which of the following might Angel Gurria agree with?
A.Agriculture means difficulty and sadness. 
B.Food prices will go down in the near future. 
C.It's almost impossible to feed 9,000,000,000 people by 2050. 
D.Both rich and poor countries should take agriculture seriously.

Not all bodies of water are so evidently alive as the Atlantic Ocean, an S-shaped body of water covering 33 million square miles. The Atlantic has, in a sense, replaced the Mediterranean as the inland sea of Western civilization. Unlike real inland seas, which seem strangely still, the Atlantic is rich in oceanic liveliness. It is perhaps not surprising that its vitality has been much written about by ancient poets.
“Storm at Sea”, a short poem written around 700, is generally regarded as one of mankind’s earliest artistic representations of the Atlantic.
When the wind is from the west
All the waves that cannot rest
To the east must thunder on
Where the bright tree of the sun
Is rooted in the ocean’s breast.
As the poem suggests, the Atlantic is never dead and dull. It is an ocean that moves, impressively and endlessly. It makes all kinds of noise—it is forever thundering, boiling, crashing, and whistling.
It is easy to imagine the Atlantic trying to draw breath—perhaps not so noticeably out in mid-ocean, but where it meets land, its waters bathing up and down a sandy beach. It mimics(模仿) nearly perfectly the steady breathing of a living creature. It is filled with symbiotic (共生的) existences, too: unimaginable quantities of creatures, little and large alike, mix within its depths in a kind of oceanic harmony, giving to the waters a feeling of heartbeat, a kind of sub-ocean vitality. And it has a psychology. It has personalities: sometimes peaceful and pleasant, on rare occasions rough and wild; always it is strong and striking.
【小題1】Unlike real inland seas, the Atlantic Ocean is______.

A.a(chǎn)lways energetic B.lacking in liveliness 
C.shaped like a square D.favored by ancient poets 
【小題2】 What is the purpose of using the poem “Storm at Sea” in the passage?
A.To describe the movement of the waves. 
B.To show the strength of the storm. 
C.To represent the vitality of the ocean. 
D.To prove the vastness of the sea. 
【小題3】In the last paragraph, the Atlantic is compared to______.
A.a(chǎn) beautiful and poetic place B.a(chǎn) flesh and blood person 
C.a(chǎn) wonderful world D.a(chǎn) lovely animal

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
【小題1】What does the underlined word “it” in the last but one paragraph refer to?

A.wealthB.hydrogenC.electricity D.fuel
【小題2】What is the problem with using hydrogen as energy?
A.It has by-products.
B.It has to be separated from other materials.
C.It will make energy too cheap.
D.It is too far away from us.
【小題3】Why does the author give the example in the last but one paragraph ?
A.To tell us that we produce energy while using hydrogen power.
B.To tell us that hydrogen power does not produce pollution.
C.To show hydrogen power can stop war.
D.To show hydrogen power is cheap.
【小題4】What is the author’s attitude about the future?
A.skepticalB.negative C.indifferent D.positive
【小題5】What is the passage mainly about?
A.war and energy B.the future of hydrogen as an energy resource
C.the disadvantages of oilD.How to end war
