How can you hear your friends’ voices when they are far away and you can’t make a long—distance call? Besides the web camera system with your computer, we have a new high-tech way to solve the problem and ease your pain of missing them.
The Japanese company Combiwith created a system—“talking picture”. It makes people in pictures speak!
The “talking picture” has a special pen. It is actually a pen-shaped scanner. It can scan information in special—made pictures. A connected player will then play the information out loud.
First, you need to take a picture and record what you want to say with the company. The company will then make special barcodes(條形碼) onto your picture(you can’t see those codes). Those codes are your voice and your words. When you hold up the pen to scan your picture with barcodes, a player connected to the pen will start to play. It plays things you’ve recorded. That way the invention makes the “you” in the picture speak!
Do you want your friends and families talking out of pictures? Have them make pictures like that, and you can hear them whenever you want, only with the “talking picture” system. The system can play messages for up to 12 minutes.
“The pictures would be useful for those who hope to hear the voice of someone living far away,” said Mayumi Fuji, a spokeswoman for the company. “Grandparents, for example, longing to know about their grandchildren, would be happy to hear their voice when they see the picture,” Fuji said.
But it is troublesome to go to the company for taking a special picture first. And, it is much more expensive than using a telephone. The photo with barcodes costs between 17,040 and 17,990 yen(日元)(160 and 169 dollars). The larger picture you want, the more you pay.
Now, just raise a finger, lonely people can have their loved ones speak out of pictures. But, whether the “talking picture” is practical or not, let’s wait and see.
小題1:What does “talking pictures” mean according to this article?
A．The picture can play what’s been recorded as if the person in the picture “talks”.
B．You can have a talk with the person in the picture whenever you want to.
C．The picture can tell you wonderful stories to ease your pain.
D．The picture can tell what’s on your mind when you are looking at it.

小題2:還是從文章第四段內(nèi)容說明是A、B、C、都對(duì)，選D。
小題3:排除題Now, just raise a finger, lonely people can have their loved ones speak out of pictures. 這句話是說動(dòng)動(dòng)手指就可以讓所愛的人說話。但是D項(xiàng)說動(dòng)動(dòng)手指就可以做一張照片所以是錯(cuò)的。
小題4:推斷題：從文章的最后一句話But, whether the “talking picture” is practical or not, let’s wait and see. 可知作者是不確定的態(tài)度。選B。

Global emissions（排放）of carbon dioxide from fossil fuel burning jumped by the largest amount on record in 2010. Emissions rose 5.9 percent in 2010, according to an analysis released on Sunday by the Global Carbon Project.
Scientists said the increase was almost certainly the largest absolute jump in any year since the Industrial Revolution. The increase solidified a trend of ever-rising emissions that will make it difficult, if not impossible, to stop severe climate change in coming decades.
The burning of coal represented more than half of the growth in emissions, the analysis found. In the United States, emissions dropped by a remarkable 7 percent in the year of 2009, but rose by over 4 percent in 2010, the new analysis shows.
“Each year, emissions go up, and there’s another year of negotiations, another year of indecision,” said Glen P. Peters, a researcher at the Center for International Climate and Environmental Research. “There’s no evidence that this path we’ve been following in the last 10 years is going to change.”
Scientists say the rapid growth of emissions is warming the Earth and putting human welfare at long-term risk. But their increasingly urgent pleas that society find a way to limit emissions have met sharp political resistance in many countries because doing so would involve higher energy costs.
The new figures show a continuation of a trend in which developing countries have surpassed (超過) the wealthy countries in their overall greenhouse emissions. In 2010, the burning of fossil fuels and the production of cement (水泥) sent more than nine billion tons of carbon into the atmosphere, the new analysis found, with 57 percent of that coming from developing countries.
On the surface, the figures of recent years suggest that wealthy countries have made headway in stabilizing their emissions. But Dr. Peters pointed out that, in a sense, the rich countries have simply exported some of them.
The fast rise in developing countries has been caused to a large extent by the growth of energy-intensive manufacturing industries that make goods that rich countries import. “All that has changed is the location in which the emissions are being produced,” Dr. Peters said.
Many countries, as part of their response to the economic crisis, invested billions in programs designed to make their energy systems greener. While it is possible, the new numbers suggest they have had little effect so far.
小題1:Many governments in the world resist limiting emissions because          .
A．it is not the best way to solve such problems
B．they don’t realize the risks of carbon emissions
C．it would probably harm human welfare in the long run
D．they are unwilling to accept higher energy costs
小題2:According to Glen P. Peters, We can learn that          .
A．the rapid growth of emissions contributes to potential risks for humans
B．rich countries actually take more responsibility for the growth of emissions
C．human beings will follow the same path of negotiations in the next 10 years
D．some countries negotiate together yearly whether to reduce the amounts of emissions
小題3:Which of the following is TRUE according to the text?
A．Emissions in the United States dropped by about 7 percent in 2010.
B．Developing countries will produce less emissions with economic development.
C．There is a long way to go for many countries to limit the fast growth of emissions.
D．Over 50 percent of the growth in emissions resulted from the burning of fossil fuels.
小題4:The text mainly talks about          .
A．a(chǎn)n analysis released by the Global Carbon Project
B．the record jump in carbon dioxide emissions
C．the possible climate change in future decades
D．the main harm of greenhouse gases

Can you imagine living in a house built by recycled waste?
Texas home builder Dan Phillips transforms trash into artful treasures, creating beautiful floors with wood pieces, kitchen counters from ivory -colored bones and roofs out of license plates （牌照）．
The fantastic houses which spring from his imagination are made almost entirely of materials which would otherwise have ended up in a garbage area．
" People have been doing this for hundreds of thousands of years; using whatever is available to build shelter, " Phillips said．"If you think about carefully what could be used, then building materials are everywhere．
The thirteen homes he has built so far would fit better in an art museum than the residential streets of Huntsville, a conservative town of about 35 ,000 people．
Living in these houses is a bit like living in a roadside attraction．"Almost every day, somebody knocks on the door and says ' Is there any way that we could see?' "said Edie Wells, an artist who rents a room in the Bone House．Her home features a stairway made of bones, floors covered in wine corks （軟木塞） and beer bottle caps．Wells said visitors are most impressed when they see a bathroom with its walls, floor and ceiling entirely covered with broken mirror pieces．
In addition, each house is highly energy efficient with plenty insulation （隔熱材料） , an on-demand solar hot water heater and a system that can collect and recycle rainwater to clean the toilet and wash clothes．
Phillips founded Phoenix Commotion 12 years ago with the aim of creating a new model for sustainable housing．For as little as $ 10,000 it builds affordable homes for single parents, low-income families and artists．
The company has used hundreds of tons of construction waste by recycling the materials into habitable buildings．
Phillips tries to spread his recycled-house idea by speaking at events across the United States, and by using the Internet to reach out to like-minded individuals．Phillips said: "I'm not going to be saving the world anytime soon．But there needs to be at least some visibility for this model in this century．

What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves –but artificial ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip (硅片) with catalysts (催化劑). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (電池), which uses those two materials to produce electricity, located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Docera at a conference of the American Chemical Society.
An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prorotype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation (轉(zhuǎn)換) inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have access to pure water.
With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new application could be widely used in developing countries, especially in India and rural China.
小題1:Which of the following order correctly shows how the artificial leaf is used to produce electricity?
a. artificial leaves split water into hydrogen and oxygen
b. the hydrogen and oxygen gases are stored in a fuel cell
c. the artificial leaves are put in water
d. the fuel cell uses hydrogen and oxygen to produce electricity
A．cbadB．cabdC．bcadD．cadb
小題2:Which of the following statements about new artificial leaves is TRUE according to the article?
A．They are inexpensive but unstable.
B．They are as efficient at carrying out photosynthesis as natural leaves.
C．They can work only in pure water.
D．They need several catalysts to help them work efficiently.
小題3:The aim of the scientists at MIT in developing the new artificial leaves is to         .
A．build-up more power stations in the world
B．provide cheaper energy for developing countries
C．offer people in developing countries access to pure water
D．gain a deeper understanding of the photosynthesis process
小題4:What is the main point of the article?
A．Introduction to the history of artificial leaves.
B．An invention copying photosynthesis.
C．Giving energy to the poor.
D．A mixture of water power and solar energy.

The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.
Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(覓食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don’t know whether this is due to an increase in the number of nests or because we have started to monitor(監(jiān)控)nesting beaches more closely.
The green turtle is the largest hard­shelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.
Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.
In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.
小題1:The main idea of the passage is to tell us________.
A．something about an endangered animal
B．how green turtles got extinct
C．how heavy a green turtle is
D．how long a green turtle can live
小題2:Which of the following is NOT a reason why green turtles are endangered?
A．Humans catch them to get profit.
B．They lose their nests.
C．They have fewer places to find food.
D．People like to keep them as pets.
小題3:According to the passage, the green turtle________.
A．can reach 100 cm in length in 17 years
B．lives in the sea and grows very slowly
C．lives only in Florida and on the Pacific coast of Mexico
D．can grow from 30 to 75 cm in 17 years in southern Florida
小題4:Why is it hard for us to know the number of green turtles?
A．Because it is difficult for us to be close to them.
B．Because we have limited knowledge about them.
C．Because we haven’t measured their growth rates.
D．Because they grow too slowly.

Playing with toy blocks (積木) may lead to improved language development in young children, a new study reported.
Early childhood is an important period in the development of young minds. The newborn brain grows three times in size between birth and age 2. Scientists have said that certain activities during this important period may promote (促進(jìn)) healthy development while others may hold it back, and development of memory and language may especially be helped by imaginative play.
After six months, language scores among half of the 175 children aged 1-1/2 to 2-1/2 who were sent plastic blocks were 15 percent higher than a matched group that did not receive the free blocks, according to the study by researchers at the University of Washington in Seattle.
Parents were given ideas about how to help their children play with the blocks, then were told to keep diaries of their children’s activities over four days. Finally, all the parents filled out questionnaires that judged their children’s vocabulary, grammar, and other language abilities. Study author Dimitri Christakis said unstructured play with blocks motivated children’s thinking, memory and physical skills at a time when a child’s brain is growing rapidly. “They are the foundation of thought and language,” he wrote of the skills learned from building blocks. “Older children begin to make up stories for these objects .”
Such play may also take the place of less helpful activities such as watching TV, he said, adding parents ought to have doubts about some toy-makers’ words. “An increasing number of media-based products are making ungrounded (無根據(jù)的) claims that they can make children smarter, more literate, and more musical,” Christakis said.
小題1:What can we learn from the second paragraph?
A．Parents should allow their children to play as long as they want.
B．The brains of kids develop very quickly before they are two years old.
C．Playing blocks can help children do well in sports at school.
D．Activities, like imaginative play, may delay the development of the brain.
小題2:According to the study, about ________ children’s language scores were 15 percent higher than those of children who didn’t play with blocks.
A．87B．55C．23D．157
小題3:Building blocks helps kids gain language skills because _________.
A．young children always talk to themselves while building blocks
B．their parents can teach them when they are playing with blocks
C．their parents are given ideas on how to develop their brains
D．it can help them improve thinking, memory and physical skills
小題4:The aim of the passage is probably to _______.
A．raise the present level of children’s language ability
B．encourage parents to let their babies play with blocks
C．improve parents’ knowledge of raising children
D．encourage makers of blocks to develop more toys
小題5:We can infer from what Mr Christakis said that _____.
A．television will be definitely replaced by blocks
B．the market will be full of media-based toys
C．we can’t always believe what toy makers say
D．toy makers care about kids’ development very much

WASHINGTON --- It’s a great achievement that inspires concepts of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a new ability: it can heal its own damage.
The new robot, which looks like a splay-legged (弓形腿的), four-footed starfish, can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places.
“There is a need for planetary robotic rovers (行星機(jī)器探測(cè)車) to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built-in computer. From the information it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking—it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One spot is the ocean floor. That dark and dangerous undersea area might be a good choice for a robot that the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
小題1:The newly designed robot distinguishes itself from the former ones because it________.
A．can communicate with people on the earth about their problems
B．works according to a certain computer program
C．can find its problems and solve them automatically
D．can explore unfamiliar places
小題2:An example is given in the fourth paragraph in order to explain that the robot ________.
A．is used to create new programs
B．has typical robot functions
C．has sensors to observe its movements
D．can gather information and adapt to new conditions
小題3:Which of the following is TRUE about the robot “Starfish”?
A．It was spoken highly of by people for its special ability.
B．It will stumble and fall if damaged.
C．It can grow its legs again once they are broken.
D．It has started to work on the ocean floor.
小題4:What might be the best title of the passage?
A．How the Starfish Robot Works
B．Do-It-Yourself Robot Repair
C．Robots Designed to Work on Other Planets
D．New Robot Helping Us in Many Ways
