One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods. 
In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.
Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.
Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(证据)to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.
But so far, no one has found bones or any other definite proof that the giant creature exists.
As a result many people believe the evidence is just part of a big trick.
The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.
They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.
【小题1】 So far what we can be sure about is that .
| A．there exist savages(野人)in several places in the world |
| B．there are some traces of hair, footprints and body prints of the “bigfoot” |
| C．bigfoot is a direct descendent of ancient gigantopithecus |
| D．all the big foot discovered have the same look |

| B．bears |
| C．gigantopithecus |
| D．people dressed in animal skins |
【小题1】B
【小题2】C
【小题3】A
【小题4】C
解析【文章大意】本文描述了“雪人”的一些目击证据并对其进行了分析说明, 也给出了一些相对比较科学的猜测。
【小题1】选B。细节理解题。的确是有“bigfoot”留下的痕迹, 到底bigfoot是谁留下的, 谁也没有把握, A项属于将猜测的东西当成事实; C项是一些人的“认为”; D项与文章描述不符。
【小题2】选C。细节理解题。根据第二段第一句“In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas and even Hubei Province in China. ”推测可知是the 1950’s。
【小题3】选A。推理判断题。由文章中“As a result many people believe the evidence is just part of a big trick. ”作者在暗示有人有意捏造证据, 骗人相信。
【小题4】选C。推理判断题。如果真的是gigantopithecus留下的脚印, 那就证明的确有这样的动物, 而整篇文章都是用的推测的语气, 由此可得答案为C。

The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.
The deserts of the world are not uninhabited(not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, pat them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.

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(矮牵牛), 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.
【小题1】Tomatoes and potatoes kill insects to ________.
| A．get more sticky hairs |
| B．make themselves grow better |
| C．make their roots stronger |
| D．avoid falling down to the ground |
| A．fastgrowing | B．harmless |
| C．insectkilling | D．nutritious |

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 (葡萄园). 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 (杀虫剂) 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.
【小题1】Farmers who grow grapes with natural and organic methods ________.
| A．don't cut grapevines every year |
| B．don't use chemicals to control harmful insects and weeds |

| A．only have to remove the dead leaves |
| B．need to remove a specific area of leaves |
| C．shouldn't remove any part of the plants |
| D．should let little lambs do the cutting |
| A．the future of getting lambs to do the cutting |
| B．the worries about using organic pesticides |
| C．the ways to get lambs to do the cutting |

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.
【小题1】 According to the passage, the planet Mars has no on it.
| A．winds | B．dust |
| C．mountains | D．animals |
| 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. |

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects．The software could eventually allow smart phone-armed soldiers to target the location of their enemies．On the home front，the software could be used by everyone，including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it．
“The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，”said Qia Wang，a doctoral student who led the development of the software．“For example，on the battlefield，a soldier needs a rangefinder，compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from War，she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video．”
Wang and his colleagues developed their software to locate and track：
Targets of known size—when the size of the target is known．a single image is enough to pinpoint the target’s location．
Targets of unknown size—If the exact size of a target is unknown，the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target，the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently，our software is limited by the physical abilities of smartphone hardware，but the devices are improving rapidly，”Wang said．“We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．”
【小题1】From Paragraph 1 we can know that the new software can.
| A．determine the speed of moving objects |
| B．1ocate objects in the distance exactly |

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(通两种语言的人)”, 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.
【小题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 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. |

Can noncombustion (非燃烧) technology create a no-pollution way to drive？Imagine pulling into a service station to fuel up your car. But not at the gas pump or electric battery charger —at the air pump! That’s not hot air, either! The next generation of cars may run on thin air. Wouldn’t that be an incredible way to cut both pollution and dependence on foreign oil?
If you’ve ever inflated a balloon and then let it go, you’ve got the basics to test-drive the amazing MiniCAT, currently being developed by Noteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you’ve ever seen. While your family’s traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs (CAT stands for Compressed Air Technology) is the air we breathe.
Start with about 25,000 gallons of air. Now, press it all into a space smaller than your school locker—because that’s the size of two super-strong, high-pressure air tanks, made from fiber and fixed beneath the air car.
Confining that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square inch. That’s over 300 times normal air pressure.
When this cold, high-pressure air enters MiniCAT’s unique engine, it interacts(交互作用) with warmer air to create pressure waves that pump the engine’s engineered pistons (活塞) to move the car. MiniCAT’s projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply.
【小题1】What is the passage mainly about?
| A．Ways to cut down air pollution. |
| B．Cars that run on thin air. |
| C．Formula One racing car designer. |
| D．Dependence on foreign oil. |
| A．The name of a car. |
| B．The name of a balloon. |
| C．The name of a car company. |
| D．The name of a car designer. |
| A．Keeping | B．Preventing | C．Pushing | D．Running |
| A．How much pressure the air creates. |
| B．How the car works. |
| C．What the normal air pressure is. |
| D．How the air gets into the engine. |

“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多种维生素make you healthier?
“We believe that the case is closed - supplementing(补充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(认知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰剂)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.
【小题1】This text is likely to be selected from a book of .
| A．medicine | B．education | C．food | D．business |
| A．Vitamins should not be used for chronic disease prevention. Enough is enough. |
| B．Having a balanced diet and exercising would probably be a better way to keep healthy. |
| C．The three studies do not provide support for use of multivitamin supplements. |
| D．Taking vitamins to replace or supplement your healthy diet is necessary. |
| A．Vitamin supplements have proved harmful to the health of adults. |
| B．Vitamin supplements are beneficial in certain conditions. |
| C．Nowadays taking vitamin supplements is common to most people. |
| D．Daily multivitamins will make you healthier. |
