International experts meeting in Australia say global carbon emissions (排放) can be reduced by more than 50 percent through simple energy saving measures. People at a conference in Australia, which increasingly relies on coal for power, say that reducing power consumption is an affordable way to both cut energy costs and reduce pollution.
While many nations turn to cheap and dirty energy sources, such as coal, to meet their increasing energy needs, analysts in Australia say the best way to meet those needs is to improve energy efficiency.
A range of simple solutions include using energy-efficient homes, household appliances and lighting, and driving electric cars. Encouraging homeowners and office workers to switch off their televisions and computers at the end of the day is also seen as an effective way to save electricity.
Grayson Heffner, from the Paris-based International Energy Agency, says reducing consumption could greatly cut global carbon emissions. He calls efficiency strategies (策略) the “soft giant” of clean energy.
“We forecast that energy efficiency will deliver something like three-quarters of the greenhouse gas emissions reductions over the next 20 years. So in the short term energy efficiency is the main way that we reduce greenhouse gas emissions but oftentimes it is not so importantly stressed in the discussions,” said Heffner.
Energy experts working in China say the government is making significant cuts in power usage.
Wan Xingwang, a Beijing-based representative of the Energy Foundation, a U.S. non-government organization, says the results have been impressive.
“In the past five years China achieved about 19.1 percent of energy reduction of its GDP. That translates to something like more than 600 million tons of coal savings,” said Wan Xingwang.
While most nations have some sort of government-sponsored energy efficiency programs, energy analysts say initiatives (主動性) by individuals and companies can also help cut demand.
Steven Nadel, executive director of the American Council for an Energy Efficient Economy, a non-profit group based in Washington, says other developing nations are recognizing the benefits of cutting power consumption and taking action.

The goal of earthquake prediction is to give early enough warning. The U.S. Geological Survey conducts and supports research on the likelihood of future earthquakes. Scientists estimate earthquake probabilities in two ways: by studying the history of large earthquakes in a special area and the rate at which strain(拉力)accumulates(積累)in the rock.
Scientists study the past frequency of large earthquakes in order to determine the future likelihood of similar large shocks. For example scientists researched the large earthquakes in the San Francisco Bay region during the 75 years between 1836 and 1911. For the next 68 years, no earthquakes of magnitude (震級) 6 or large occurred in the region. Beginning with a magnitude 6 shock in 1979, the earthquakes in the region increased dramatically; between 1979 and 1989, there were four magnitude 6 or greater earthquakes, including a magnitude 7.1 earthquake. So scientists estimated that the probability of a magnitude 6.8 or larger earthquake occurring during the next 30 years in the region is about 67 percent.
Another way to predict earthquakes is to study how fast strain accumulates. When plate movements build the strain in rocks to a critical level, like pulling a rubber band too tight, the rocks will suddenly break and slip to a new position. Scientists measure how much strain accumulates along a fault (斷層) each year, how much time has passed since the last earthquake, and how much strain was released in the last earthquake. This information is used to calculate the time required for the accumulating strain to build to the level that results in an earthquake. This simple model is so complicated that such detailed information about faults is rare. In the United States, only the San Andreas Fault System has adequate records for using this prediction method.
Scientific understanding of earthquakes is of vital importance to the Nation. As the population increases, expanding urban development and construction encroach (侵蝕) upon areas susceptible(易受影響的) to earthquakes. With a greater understanding of the causes and effects of earthquakes, we may be able to reduce damage and loss of life from this destruction.

It’s a sure sign that summer is over and winter is on the way — leaves that were once deep green turn red, yellow and bright orange. It happens every autumn. But did you ever wonder why?
The leaves start changing color when the nights start getting longer and the temperature starts getting cooler. Some scientists think that as the number of daylight hours shrinks, the leaves stop making chlorophyll which makes plants green. The reason is that the process of making chlorophyll requires sunlight. But according to horticulture (園藝) educator Susan Rose from Colorado State University, it turns out leaves don’t really change color at all. “The fall colors are actually there all along,” she said. “But they are covered by the green chlorophyll. As the chlorophyll stops being produced, the other colors can shine through.”
The kind of color that the leaves are going to change to is determined by the plant’s genetic (基因的) background. In some places, the leaves start changing color in September — before autumn even officially begins. In other places, they don’t change until late October or even November. Some scientists say the leaves have been changing color later than usual in recent years. And they think global warming has something to do with that.
In one study, researchers found that the growing season in the Northern Hemisphere was nearly a week longer, on average, in 2008 than it was in 1982. And a professor from Harvard University found that the leaves, west of Boston, Massachusetts, are changing color about three days later than they used to. However, other scientists disagree with the global warming theory. Susan Rose said the leaves in her part of Colorado are changing “right on schedule.” But the leaves in other parts of that state are running a little late. “The lateness in the mountains may have something to do with the really warm late summer and early fall,” she said. “But I’m afraid that’s just a guess.”
【小題1】According to Susan Rose, _____.
A.the fall colors are always in leaves |
B.leaves make chlorophyll all the seasons |
C.leaves’ changing color have nothing to with the weather |
D.leaves begin changing color because they start making chlorophyll |
A.reduces | B.increases | C.lasts | D.a(chǎn)ppears |
A.genetic background | B.dry weather |
C.global warming | D.low temperature |
A.why leaves change color at fall |
B.leaves change color at different time |
C.the effects of the global warming on plants |
D.different opinions on the lateness of leaves’ changing color |

Just when scientists think they have discovered and recorded every species of insect that crawls the earth they find something new. Earlier this month, Peter Jager, the head of Frankfurt’s Senckenberg Research Institute reported the discovery of a unique eyeless spider.
The creature that has a leg span (跨度) of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species. However, the other members of the family all have eyes. The spider is the first one that has no eyes. They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such a degree that they have dispensed with them altogether.
But they are not the only creature to have done that. Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider!
Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the south and Thailand on the west, the landlocked nation of Laos is filled with a large number of new and exotic (新奇的) species. In the last few years researchers have discovered the Saola—never-before-seen antelope-like creature, a small deer species called muntjacs, a tiny stripped rabbit and a rock rat that was thought to have been extinct 11 millions years ago. In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians (兩棲動物) and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households.
64. 【小題1】Which of the following is the best title of passage?
A.Laos full of a large number of exotic species |
B.Laos popular with plenty of strange species |
C.Every species of insect discovered and recorded by scientists |
D.World’s first eyeless spider discovery in Southeast Asia. |
A.The eyesight, identification and family members. |
B.The size, identification and the reason for being eyeless |

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing when you are happy. Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims (聲稱) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your house is your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away. If so, you have actually frightened the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting (筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
【小題1】Some scientists believe that most of the time bird’s singing is actually ________.
A.an expression of happiness B. a way of warning
B.an expression of anger D. a way of greeting
【小題2】What is a bird’s “territory”?
A.A place where families of other species are not accepted. |
B.A place where a bird may shout at the top of its voice. |
C.An area for which birds fight against each other. |
D.An area which a bird considers to be its own. |
A.Because they want to invite more friends. |
B.Because their singing helps frighten outsiders away. |
C.Because they want to find outsiders around. |
D.Because their singing helps get rid of their fears. |
A.By comparing birds with human beings. | B.By reporting experiment results. |
C.By describing birds’ daily life. | D.By telling a bird’s story. |
A.哭喊聲 | B.令人驚愕的 | C.尖叫聲 | D.尖叫的 |

More than 200 scientists have completed a twoyear study to identify the most natural and undeveloped areas on Earth. Their findings are reported in a new book called Wilderness:Earth’s Last Wild Places. The book describes 37 wilderness areas around the world. Each has an area greater than 10,000 square kilometers. The study considered only areas where at least 70% of all plants are native.
North and South America are home to the largest number of wilderness areas. There are 16 such areas, from southern Argentina to Alaska and northern Canada. Africa has 8 wilderness areas, including the thick forests and the grasslands. Australia and New Guinea (幾內(nèi)亞) share 6 areas. Europe has 3 areas and Asia has 2.The Arabian Desert and Antarctica also are considered wilderness areas.
The largest wilderness area is the Boreal Forest (北方森林).It extends for 16million square kilometers south of the Arctic Circle. The Boreal Forest extends across Alaska, Canada, northern Europe and Russia. The smallest of the 37 wilderness areas is the Sundarbans. It is the world’s largest tidal mangrove forest (紅樹林).It covers 10,000 square kilometers of land at the mouth of the Ganges River in India and Bangladesh (孟加拉國).
The study found that wilderness areas cover about 46% of the Earth’s land surface. However, they are home to less than 2.5% of the world’s population. Nineteen of the wilderness areas have only about one person for each square kilometer. Native people usually live in these areas.
Wilderness areas help to influence the world’s weather systems and rainfall. They are also home to many plants and animals. Population growth and the spread of agriculture and mining operations threaten wilderness areas. But just 7% of all such areas have some form of official protection.
【小題1】What does the author think of the wilderness areas around the world in the book?
A.Unwanted. | B.Long-lasting. | C.Valuable | D.Perfect. |
A.a(chǎn)re worth the public support | B.can attract readers’ attention |
C.need to be stressed as resources | D.a(chǎn)re seen on every continent |
A.deserted | B.crowded | C.uncontrolled | D.undeveloped |
A.thought more of by the governments | B.explored as natural habitats very soon |
C.further made full use of at present | D.discovered for their advantages of nature |
A.the importance | B.the situation | C.the development | D.the environment |

We each have a memory(記憶力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.【小題1】

Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.
The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.
In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms --- the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?
Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.
In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.
【小題1】The first two paragraphs were written to show that ________.
A.the Pyramid of the Sun is an unusual historic building |
B.a(chǎn)ncient Egyptian emperors were cruel |
C.construction workers led a hard life in ancient Egypt |
D.the secrets of the pyramids remain to be uncovered |
A.To try to unlock some of its secrets. |
B.To stop robbers from finding the treasures inside. |
C.To refuse some visitors all over the world into it. |
D.To tell the truth to the people in the future. |

Air is an odorless (無氣味的), invisible (看不見的) gas that surrounds the earth. It is everywhere on the planet. An “empty” drinking glass and an “empty” room, to give two examples, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite (明確的) shape, but, because it is matter, it takes up space. It is easy to prove that air is something that takes up space. Stuff a dry handkerchief into the bottom(底部) of a glass so that it will not fall out when the glass is turned upside-down. Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.
【小題1】What does the underlined word “Stuff” (in Paragraph 2) mean?
A.Press tightly. | B.Take out. |
C.Put down. | D.Turn fully. |
A.the experiment is done in the laboratory |
B.the experiment is done outside the room |
C.the experiment is easily done |
D.the experiment is carried out indoors |
