Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?
Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
Lost in the Wild
Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
Turkestanian salamander
This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
Gastric brooding frog
Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
Rio Pescado stubfoot toad
Last sighting: 1995, in South America
Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.

“If you want to see a thing well,reach out and touch it!”
That may seem a strange thing to say.But touching things can help you to see them better.
Your eyes can tell you that glass ball is round.But by holding it in your hands,you can feel how smooth and cool the ball is.You can feel how heavy the glass is.
When you feel all these about the ball,you really see it.
With your skin,you can feel better.For example,your fingers can tell the difference between two coins in your pocket.You can feel a little drop of water on the back of your hand,too.
You can even feel sounds against your skin.Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch!” means.They hear it often.Yet most of us keep on touching things as we grow up.In shops,we touch things we might buy,such as food,clothes and so on.To see something well,we have to touch it.
The bottoms of our feet can feel things,too.You know this when you walk on warm sand,cool grass or a bad floor.All feel different under your feet.
There are ways of learning to see well by feeling.
One way is to close your eyes and try to feel everything that is touching your skin.Feel the shoes on your feet,the clothes on your body,the air on your skin.At first,it is not easy to feel these things.You are too used to them!
Most museums are just for looking.But today some museums have some things to touch.Their signs say,“Do touch! There you can feel everything on show.If you want to see better,reach out and touch.Then you'll really see!”

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率),which instead focus on architectural and technological developments.
‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher,‘consumption patterns of building users can defeat the most careful design. ’In other words,old habits die hard, even in the best-designed eco-home.
Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information,it’s hard to estimate the costs and benefits of making different choices. Feedback (反饋) facilities, like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension (方面),suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒溫器) , for example.
Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.
【小題1】As to energy use, the new research from UKERC stresses the importance of________.
A. zero-carbon homes | B.the behaviour of building users |
C. sustainable building design | D.the reduction of carbon emissions |
A.the ways | B.their homes |
C. developments | D.existing efforts |
A. The importance of changing building users, habits. |
B. The necessity of making a careful building design. |
C. The variety of consumption patterns of building users. |
D. The role of technology in improving energy efficiency. |
A. can be bridged by feedback facilities |
B. affects the study on energy monitors |
C. brings about problems for smart meters |
D. will be caused by building users’ old habits |
A. The social science research is to be furthered. |
B. The education programme is under discussion. |

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牽牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants,” they added.
【小題1】Tomatoes and potatoes kill insects to ________.
A.get more sticky hairs |

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls,” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school,” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.
【小題1】According to the passage, we can know ________.
A.it's a good habit to play with smartphones or iPads late into night |
B.scientists suggest we should avoid using smartphones or iPads |
C.darkness makes a great impact on the amount of melatonin |
D.the sun was the only source of light in ancient times |
A.The darker it is, the more melatonin will be produced. |
B.The lighter it is, the more melatonin will be produced. |
C.The more melatonin you have, the worse you'll sleep. |
D.The more electrical equipment you have, the more melatonin will be produced. |
A.who are young adults or adolescents |
B.who don't perform well in school |
C.who are addicted to a television or laptop |
D.who are short of sleep at night and perform poorly in daily life |
A.You should go to bed when the sun goes down. |
B.You should use an orange or red light electronic screen. |
C.You should wear a pair of blue sunglasses when sleeping. |
D.You should avoid blue light as possible as you can before bedtime. |

Growers around the world are using new methods to grow grapes to make wine. They use natural and organic methods to control harmful insects and weeds instead of using chemicals. Now, a winery in Canada has adopted a natural way to control its grapevines (葡萄藤). The Featherstone Winery is in southern Ontario. The grapevines, like other plants, need to be cut every year.
Cutting grapevines must be done very carefully. Only a targeted area of leaves is removed from the lower part of the vines to help the grapes grow better. But at the Featherstone Winery, no man or machine does the cutting. Instead, the job is done by 40 little wooly lambs.
David Johnson owns the vineyard (葡萄園). He says he learned about using lambs while visiting wineries in New Zealand. The young lambs are perfectly designed to do the job. They eat the grape leaves on the lower parts of the vine. But they are not tall enough to reach the grapes. They only weigh about 22 kilograms, so they do not beat down the soil. And their waste makes good organic fertilizer. In addition, using the lambs costs much less than hiring workers to cut the vines for seven weeks in summer. And when the cutting is done in August, the lambs become tasty dishes.
Mr. Johnson says he had a difficult time finding enough lambs to do the job. There are about 50 million lambs in New Zealand. But there are not nearly as many in Ontario. Also, some organic pesticides (殺蟲劑) are harmful to lambs. And the lambs must be watched to make sure they do not eat too much of the grapevines.
David Johnson says the lambs help him carry out his environmental ideas about farming. They are lovely and peaceful and he likes having them in his vineyard. People visiting the vineyard also enjoy watching the lambs do their job.
【小題1】Farmers who grow grapes with natural and organic methods ________.
A.don't cut grapevines every year |

At first sight the planet Mars(火星)does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles(161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes(火山); the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between
100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
【小題1】 According to the passage, the planet Mars has no on it.
A.winds | B.dust |
C.mountains | D.a(chǎn)nimals |
A.there is a large amount of ice at the poles |
B.there is a thicker and warmer atmosphere |
C.there are some kinds of simple plants |
D.there are many active volcanoes |
A.Certain gases should be used to warm the Mars. |
B.Plants should be grown to make the Mars fit to live on. |
C.The Mars could support life on right conditions in the future. |

If you think English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the earlier people learn a second language, the greater the effect is.
A team led by Dr. Andrea Mechelli, from University College London(UCL), took a group of Britons who only spoke English. They were compared with a group of“early bilinguals(通兩種語(yǔ)言的人)”, who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,”said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills.
“Having two languages gives you two windows on the world and makes the brain more flexible,”he said,“You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing and comprehension were all tested. The results showed that the earlier they started to learn, the better.“Studying a language means you get an entrance to another world,”explained the scientists.
【小題1】What does the underlined part“grey matter”(in paragraph 2) refer to?
A.Grey hair. | B.Material of the brain. |
C.Intelligence. | D.Difficult situations. |
A.change one’s brain completely |
B.improve one’s maths skills |
C.make one smarter than others |
D.increase the ability to learn |
A.the researchers from UCL did another study in Italy |
B.a(chǎn) similar study was done on native Italian speakers who learn English as a second language |
C.the research done on the Italians showed a totally different result |
D.it will be easier for one to travel around the world by learning a second language |
A.Learning a second language can help improve your brain power. |
B.You should learn a second language in English that is not your native language. |
C.If you want to learn a second language, you should do it at a certain age. |
D.The research done by the researchers from UCL is very successful. |

Where do you find out about the world’s longest walk? The world's tallest man? The world's oldest woman? You know the answer, of course. It is the Guinness Book of World Records. How would people find such unusual facts without this book?
Guinness Book did not exist until 1951. Here is what happened. The managing director of Guinness Brewery was a curious man. He wanted answers to some questions about records. For example, he wanted to know what was the fastest flying game bird in Europe. But he was frustrated. There was no book to answer questions like this.
The director, Sir Hugh Beaver, contacted the McWhirter twins. They were brothers who owned a research agency. He asked them to put together a new reference book. It would include all kinds of unusual records. The brothers quickly accepted. The first edition of their book was published in 1955. Soon the Guinness Book of World Records was a best seller. It has sold more copies than any book except the Bible. A new edition is published every year.
Where do all the book's records come from? They are a combination of things like natural wonders, sports records, and stunts(特技) (How many people would push an egg with their noses if they weren’t trying to get to the book?). But the editors try to keep things honest. All records must be verified by an investigator. Only then are they printed.
The Guinness Book is a big business. It is published in dozens of languages. There are TV shows and museums. It is proof of how interested people are in strange pieces of information.
【小題1】The passage is mostly about _____.
A.the McWhirter twins |
B.the director Sir Hugh Beaver |
C.unusual records in the Guinness Book |
D.a(chǎn) history of the Guinness Book |
A.is a best seller |
B.is published only in English |
C.does not always check its records |
D.has a full-length movie based on it |
A.wanted to publish the book so that they set up a research agency |
B.owned so good a research agency that they liked to help others |
C.recognizes that Sir Hugh's idea for a book was a good one |
D.wanted to know the answers to some questions about records |
A.questioned | B.proved the truth | C.written up | D.blocked |
