When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Sea lions and seals may swim in cold ocean water, but even they get chilly sometimes. Seeing an injured seal wrapped in a blanket at a marine(海的) mammal center gave Haley Humes and Hayley Jeffries an idea for a special Girl Scout project. They decided to make blankets to keep injured animals warm. They would give these blankets to the Pacific Marine Mammal Center in Laguna Beach, California.
“We knew we wanted to help animals,” Haley said. “We went to the center to ask questions about what they needed. They don’t have a heated floor, and all the babies crowded together to stay warm.”
Friends since kindergarten, Haley and Hayley made 12 blankets to keep the Marine Mammal Center’s seals and sea lions warm. Using fun images like Winnie-the-Pooh, the girls took two hours to make each blanket. The first sea lion to test out a blanket looked pretty in pink.
“It was a sick baby and really liked it,” Haley said. “It curled up in it right away.”
“The blankets are beautiful and the animals love them!” said the Mammal Center’s Michele Hunter. “It’s nice to see children taking pride in their work and doing something to help animals.”
During the project, the girls took dozens of pictures for the PowerPoint presentations they gave to Girl Scout leaders. Those presentations helped Haley and Hayley raise $250 to buy additional supplies the center needed.
This was the first project the girls ever worked on and took months to plan and carry out.
“I learned that in order to make something happen, you have to take it slowly and step by step,” Hayley said. Just as important, the girls discovered that two people really can make a difference. “Knowing you’re making a difference……with these animals is amazing,” Haley said. “It was like the animals became my new friends.”
The Pacific Marine Mammal Center cares for sea lions and seals, as well as for other marine mammals. Since opening in 1971,the center has saved more than 5,000 injured marine mammals.
小題1:          What does the underlined word“ chilly” in Paragraph 1 mean?
A．Sick. B．Cold.C．Afraid. D．Bored.
小題2:          When Haley and Hayley saw an injured seal wrapped in a blanket, they_____.
A．decided to help animalsB．a(chǎn)sked Girl Scout for help
C．went to the animal center to work.D．called on others to protect animals
小題3:          What can we learn about Haley and Hayley from the text?
A．They raised $2,500 for the Mammal Center.
B．They made 120 blankets by themselves.
C．It took them an hour to make a blanket.
D．They felt great about what they did.
小題4:          Which of the following words can best describe the work of Haley and Hayley?
A．Difficult.B．Successful.C．Experimental.D．Dangerous.

Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions（排放）vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators（發(fā)電機(jī)）. Generators are fueled by something--usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal（地?zé)幔?plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes—“If I can't see it, it's not happening.”  Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas（or another fuel）and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.
A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far -- so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.
　　In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though，all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.
小題1:What’s the main idea of the passages?
A．Electric cars aren’t actually clean.
B．Electric cars are zero-emissions vehicles.
C．Zero-emissions vehicles are popular.
D．Gasoline-powered cars are more efficient.
小題2:Which of the following words can replace “be clueless about” in Paragraph 2?
A．Be familiar with．
B．Be curious about．
C．Fail to understand．
D．Show their interest in．
小題3:The electricity we get from a gallon of gas may make our car run _________.
A．a(chǎn)t least 25 miles
B．more than 25 miles
C．a(chǎn)s far as 25 miles
D．less than 25 miles
小題4:In the author’s opinion, compared with cars using gas, electric cars are more __________.
A．environmentally-friendlyB．expensive
C．efficientD．harmful
小題5:It can be inferred from the passage that __________.
A．electric cars' batteries are poisonous for a long time
B．now electric cars are used more than their gasoline-powered cousins
C．zero-emissions vehicles should be chosen to protect our environment
D．electric cars are not clean in that we get electricity mainly by burning something

Motherhood may make women smarter and may help prevent dementia（癡呆） in old age by bathing the brain in protective hormones（荷爾蒙） , U．S．researchers reported on Thursday．
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s（早老癡呆癥）．University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans．“Our research shows that the hormones of pregnancy（懷孕） are protecting the brain, including estrogen（雌激素）, which we know has many neuroprotective （保護(hù)神經(jīng)的） effects,” Kinsley said．
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview．“They go through pregnancy and hormonal changes．” Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline．
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida．
“They do not realize that hormones are washing on the brain．If you look at female animals that have never gone through pregnancy, they act differently toward young．But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations（改變） to the brain．”
小題1:How do scientists know “Motherhood may make women smarter”?
A．Some researchers have told them．
B．Many women say so．
C．They know it by experimenting on rats．
D．They know it through their own experience．
小題2:What does the phrase “l(fā)itters of pups” mean in the second paragraph?
A．Baby rats．B．Animals．C．Old rats．D．Grown-up rats．
小題3:What can protect the brain of a woman according to the passage?
A．Estrogen．
B．The hormones of pregnancy．
C．More exercise．
D．Taking care of children．
小題4:“It’s rat data but humans are mammals just like these animals are mammals．” What does the sentence suggest?
A．The experiments on the rats have nothing to do with humans．
B．The experiments on the rats are very important for animals．
C．The experiments on the rats are much the same on humans．
D．The experiments on the rats are much the same on other animals．

School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, he can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to learn some facts or a formula by heart. It is actually quite easy to learn a certain fact in history or a formula(公式) in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientist, such as Einstein, Newton and Galileo, didn’t get everything from school. But they were all so successful and invented so many things for men. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.
小題1:According to the passage, a good teacher should be one who is to_________.
A．help his students to gain a good memory.
B．train his students’ ability to learn
C．teach his students everything he knows
D．have his students studying long hours
小題2: If a student want to learn better, the most important thing for him to do is_______.
A．to learn all the useful facts and formula by heart
B．to do everything as his teacher have said in class
C．to absorb (吸收) as much knowledge from his teacher as possible
D．to think more while he is studying

Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman Empire. But when the empire broke down，this kind of tourism stopped.
　　In the early 17th century, the idea of the “Grand Tour” was born. Rich young English people sailed across the English Channel（英吉利海峽）.They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice（威尼斯）in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The “Grand Tour” was an important part of young people’s education—but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to” take the waters”. They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
　　In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.
　　Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far away countries.
　　The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
　　Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food—and tourists pay for it all before they leave home. The package tour and modern tourist industry was born.
　　The first travel agency in China was set up as early as 1949.But tourism did not take off until 1978.In 2002,the industry was worth 500 billion yuan and became an important part of China’s social development.
小題1:In the early times, the travelers ________.
A．a(chǎn)ll came from Roman
B．were very young and strong
C．had lots of money
D．traveled by boat
小題2:________ played the most important role in the tourism development.
A．EducationB．MoneyC．TransportationD．People’s ideas
小題3:Modern tourism was born ________.
A．in 1949B．in Roman times
