Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut he greenhouse gases they send out, which are thought to be responsible for global warming.
Thanks to special bacteria in their stomachs, kangaroo flatulence(腸胃氣脹)contains no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack (煙囪) pushing out carbon dioxide, farm animals’ passing wind contribute a sur­prisingly high percentage of total emissions (排放物)in some countries.
“Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Kleve, 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're 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 (分離) 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.
The idea is controversial (有爭議的), but about 20 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 Amp of the University of New South Wales's institute of environmental studies.
小題1:Scientists intend to put bacteria into cattle and sheep _________.
A．so that they can make full use of special bacteria
B．to help Australian farmers to earn more money
C．so that they can protect Australian ecosystem
D．to prevent them from sending out harmful gases
小題2:Athol Kleve seems to believe that ________.
A．cattle and sheep produce more carbon dioxide
B．less cattle and sheep are raised in New Zealand
C．farm animals are responsible for greenhouse gases
D．New Zealand has the most animals in the world

A．Australians should farm fewer cattle and sheep and just eat more kangaroos.
B．The bacteria could make the digestive process much more efficient.
C．Australians should give kangaroo - style stomachs to cattle and sheep.
D．The bacteria could save millions of dollars in feed costs for farmers.

Over a period of time, many habitats (棲息地)change with respect to the types of plants and animals that live there. This change is known as succession.
Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting（產(chǎn)生）of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance (增加)the soil. Pine seedlings (苗)soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory (山核桃)seedlings, however, that have found the forest floor suitable.  These seedlings grew into large trees that eventually shade out the pines.
小題1:The best title of this passage is _____.
A．The Importance of Weeds and Grasses
B．The Success of Oak and Hickory
C．How Environmental Habitats Change
D．Animal and Plant Habitats
小題2:It can be inferred (推理) from the passage that ______.
A．oak and hickory trees grow taller than pines
B．weeds and grasses prefer cold climate
C．pines and grasses can exist together
D．birds encourage the growth of shrubs
小題3: Which of the following is a stage of succession as described in the passage?
A．A forest cut down to build an airport.
B．A flood washing away a crop of wheat
C．Wild flowers growing in an unused parking lot
D．Animals being tamed (馴服)by children

Electrical devices(儀器)could soon use power made by human energy. Scientists say
they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.
The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.
小題1:The second paragraph mainly talks about     .
A．who developed the device
B．how the device works
C．several possible uses for the devices
D．how much electricity the device can produce
小題2:What is the disadvantage of the experimental version of the device?
A．It is too heavy for the walker to bear.
B．It is too complex for people to use.
C．It is too expensive for most people to afford.
D．It will slow down one’s walking speed.
小題3:Compared with the device designed by Larry Rome, this new device     .
A．produces power without adding more loads to the walker
B．can produce more power in a much shorter time
C．needs to be equipped with a battery
D．can help the walker wa1k faster
小題4:From the passage, we can learn that the electrical device can     .
A．help housewives operate the washing machine
B．make it much easier for us to go online
C．produce more electricity than that invented by Larry Rome
D．be applied in medicine to operate heart pacemakers
小題5:What would be the best title for the passage?
A．First device powered by walking wi1l soon be on the market
B．Advanced technology brings in a new way to operate heart pacemakers
C．Device gives new meaning to the idea of power walking

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing?Paper,No notebooks,no test paper.Nor are there any pencils or pens,which always seem to run out of ink at the critical moment.
A“paperless classroom”is what more and more schools are trying to achieve.Students don't do any handwriting in this class. Instead, they use palm (手掌) size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student's personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they're studying from math to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan (阿富汗) over one year ago.
"We could touch every side of the country through different sites? from the forest to refugee camps (難民營)," she said. "Using a book that's three or four years old is impossible."
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
"Think about the money and trees we could save with the computers," she said.
But, with all this technology, there's always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
小題1:What does the part of the last sentence in the first paragraph, “run out of ink at the critical moment”, mean?
A．Pens may not write well at the critical moment.
B．Pens get lost easily, so you may not find them at the critical moment.
C．Pens may have little or no ink at the critical moment.
D．Pens use ink, while pencils don't.
小題2:In a paperless classroom, what is a must?
A．Pens.B．Computers.C．Information.D．Texts.
小題3:The high school teacher, Judy Herrell, used the example of her class to show that _______.
A．the Web could take them everywhere
B．the Web taught them a lot
C．the Web is a good tool for information
D．the Web better than the textbooks, can give the latest and comprehensive (全面的) information
小題4:The paperless classrooms will benefit _____ the most.
A．studentsB．teachersC．treesD．computers
小題5:What does the phrase in the last paragraph, “break down”, mean?
A．Break into pieces.B．Stop working
C．Fall down.D．Lose control.

Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr. Leachim, who weights two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, their parents’ names, and what each child knows and needs to know. In addition, he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification (識別) number. His computer brain puts the child’s voice and number together. He identifies the child with no mistakes.
Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off.

To master a language one must be able to speak and understand the spoken language as well as to read and write．Lenin and his wife Krupskaya translated a long English book into Russian．But when they went to England in 1980, English people couldn’t understand what was said to them．These days more foreigners are coming to China and more and more Chinese are going out to foreign countries to work or study．So the spoken language is becoming more and more important．Speaking, of course, can’t go without listening．If you want to pronounce a word correctly, first you must hear it correctly．The sounds of the Chinese and English language are not exactly the same．If you don’t listen carefully, you’ll find it difficult or even impossible to understand the native speakers．
Well, what about writing? Like speaking, it’s to exchange ideas．People generally use shorter words and shorter sentences in their writing．The important thing is to make your idea in your head and then to write it in clear lively language
Chinese students read far too slowly．If you read fast, you understand better．If you read too slowly, by the time you have reached the end of a page you have forgotten what the beginning is about．When you meet with new words, don’t look them up in the dictionary．Guess the meaning from the context．You may not guess quite correctly the first time, but as new words come up again and again in different contexts, their meaning will become clearer and clearer．If you look up every word, you’ll never finish a book．
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they’re studying．They should study these subjects in the foreign language, not only in translation．In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time．

I remember as a small child when we would have these gatherings where someone would come up and ask, “What are you going to be when you grow up?”?
Well, it    41   being a cowboy or some super hero. Later it was a fireman, policeman, lawyer ... As I grew older my dreams of the future   42  . When, at last, I was in college, I made up my   43    to become a preacher(牧師) as my father.    44    I studied and prepared for that life. I reached    45  in the end and I was preaching nearly fulltime for much of my adult life.
However, for many, there is a “thief” which goes around stealing our   46   . Sometimes, the thief will come as a parent, a relative, or a friend, but the    47   thief is, so many times, just    48  .?
We find ourselves just about reaching the top, and this “small”    49    inside says, “You will never make   50   .” “You can’t possibly do this.” And on and on the “small” voice 51       some kind of failure. Failure, though, is exactly how dreams are    52   . It is one of the most important tools we have, because it teaches us invaluable   53   .

The message I always gave my children was that you   55   do anything your heart desires.

Restoring the quake­hit ecosystems is a question of balancing the interests of the local people and the environment. Rural methane (沼氣) projects can reduce the number of locals taking firewood from the mountainsides. The use of straw as food for animals will ensure that vegetation(草木) can grow. In Sihai township and Dazhuangke village, in Beijing, they now have a forestry coverage of 85% or more, compared to the 30% they had 15 years ago. Back then, land was used very inefficiently: one person would use 20 mu of forest just for firewood. With those pressures on the ecosystem, no amount of spending on reforestation will succeed. Then the government relocated the population and paid those who remained to tend the forest and provide coal. This reduced the pressures on the ecosystem and it was able to recover naturally.
When an ecosystem has not been pushed past certain limits, it is able to recover on its own. Human involvement should only play a minor role, including after an earthquake. This is particularly the case for sandy grasslands, grasslands deserts, the mountains of the south and the northern sides of mountains in the north. In these areas soil remains and the water, light, heat and nutrients needed are available. Less human involvement is even more appropriate in areas with a small population, where it can avoid money being wasted on ineffective efforts, such as creating forests in dry areas.
The creation of nature reserves should be a model to allow damaged ecosystems to recover. Funding can start at the national level; centrally­funded nature reserves can enforce environmental protection laws and help to promote the local economy. This will solve the problems of reserves being run to make money. When national reserves are funded, local governments will be able to adopt the same model and provide the funds for nature reserves from their own budgets. The first project should be established in nature reserves hit by the quake; these can then become models for other areas.
小題1:To restore the quake­hit ecosystem, government should ________.
A．forbid locals from taking firewood from the mountainsides
B．encourage local people to feed their animals just with straw
C．spend large amounts of money relocating the population
D．protect the environment without harming locals' interests
小題2:The forestry coverage in rural Beijing has increased greatly because ________.
A．pressures on land were reducedB．a(chǎn) large amount of coal is provided
C．no people live in that areaD．locals take good care of the forest
小題3:According to the passage ________ play(s) a major role in ecosystem recovery.
A．local peopleB．nature itself
C．human involvementD．government's effort
小題4:According to the last paragraph, which of the following is NOT true?
A．Nature reserves could be helpful to recover the damaged ecosystems.
B．Centrally­funded nature reserves are beneficial to local economy.
C．Some nature reserves are created for the purpose of making money.
D．The first projects on nature reserves should be set up in quake­hit areas.
