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.

The Batsquatch is described as a great winged bat. It’s reported that it lives in the shadows(陰暗處) of Mt. Saint Helens. It has purple skin, red eyes and the character is quite similar to the bat’s. Since reports tell it likes eating small animals like chickens, goats and pigs, some believe that it is actually a flying primate(靈長目動物). But researchers say that it is more closely related to the fruit bat of northern America.
Fear still fills the hearts of men, women and children of Washington. In May of 1980 during the eruption of Mount Saint Helens, the Batsquatch showed itself in the shadows of clouds from the eruption. In 1994, a local mountaineer was able to take pictures of the Batspuatch making the rumor(謠言) seem real. During this event some farm animals seemed to disappear though luckily no humans were reported missing at the time. The local mountaineer told about his meeting with the Batsquatch. When he suddenly heard a loud deep voice from the shadows, the mountaineer was knocked down. He tried to look for the creature(生物) that had made the sound. He saw a great creature with purple wings in the sky. It looked like it was about 30 feet tall.
The mountaineer kept this story a secret in fear of being laughed at by others but when new stories came in about the Batsquatch he shared his story.
The reality of the Batsquatch can no longer be ignored. It is only a creature that is trying to live. Respect! This is how we should take news such as this. Respect for a living creature instead of fear.
【小題1】The rumor about the batsquatch makes people of Washington full of______
A.joy | B.surprise |
C.fear | D.a(chǎn)nger |
A.Because it was reported in the newspaper |
B.Because it was seen by many local people |
C.Because someone once caught one |
D.Because someone took its picture |
A.heard nothing strange |
B.shouted at it to frighten it away |
C.was lying on the ground, relaxing |
D.found it was a 30-foot-tall creature that could fly |
A.was afraid of being laughed at |
B.was too frightened to tell others |
C.couldn’t believe what he saw |
D.didn’t want to make fun of others |
A.the Batsquatch is being endangered |
B.the Batsquatch is a dangerous creature |
C.respect should be given to the Batsquatch |

Global Positioning Systems (全球定位系統(tǒng)) are now a part of everyday driving in many countries.These satellitebased systems provide turnbyturn directions to help people get to where they want to go.However,they can also cause a lot of problems,send you to the wrong place or leave you completely lost.Many times,the driver is to blame.Sometimes a GPS error is responsible.Most often,says Barry Brown,it is a combination of the two.
Barry Brown is with the Mobile Life Centre in Stockholm,Sweden.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPSequipped car to use during his stay.Mr Brown says,“They just plugged in an address and then set off to their destination.And,then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again,the GPS is kind of ‘garbage in garbage out’.”
Mr Brown says this is a common human error,but what makes the problem worse has to do with some of the shortcomings,or failures,of GPS equipment.He says,“One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn,sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Mr Brown says,“One of the things that struck us,perhaps the most important thing was that you have to know what you’re doing when you use a GPS.There are these new skills that people have developed.There are these new competencies (資格) that you need to have to be able to use a GPS because they sometimes go wrong.This goes against a common belief that GPS systems are for passive drivers who lack navigational skills.”
Barry Brown says to make GPS systems better we need a better understanding of how drivers,passengers and GPS systems work together.
【小題1】According to Barry Brow,in most cases,________are blame for the problems.
A.human errors |
B.GPS errors |
C.errors caused by both drivers and GPS |
D.errors caused by putting in a wrong address |
A.GPS is nothing but garbage |
B.GPS is still not accurate enough |
C.it is difficult for drivers to use GPS equipment |
D.sometimes drivers are responsible for the problem |
A.it’s impossible to drive from the east to the west in the US |
B.Barry Brown’s friend went to Stockholm,Sweden by plane |
C.given wrong instructions,the GPS will produce wrong results |
D.GPS systems are for passive drivers who lack navigational skills |
A.It just tells the driver to turn once at a time. |
B.It gives the driver the overview. |
C.Its screen is too small to be seen clearly. |
D.It is only suitable for passive drivers. |
A.GPS systems are helpful for drivers. |
B.Driving with GPS can be difficult to navigate (導航). |
C.Drivers should understand how GPS systems work. |
D.Drivers should learn to use GPS systems correctly. |

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.
【小題1】 Which of the following animals hasn’t been seen for over a century?
A.Rio Pescado stubfoot toad. |
B.Gastric brooding frog. |
C.Turkestanian salamander. |
D.Scarlet frog. |
A.the scarlet frog used to live in Africa |
B.researchers have no way to save amphibians |
C.the scientists will search 14 countries at most |
D.Robin Moore has begun his search for amphibians |

The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飛行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04:35 Beijing time on Saturday (20:35 GMT).It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.
Ma Xingrui, chief mander of China's lunar programme, declared the mission (任務(wù))a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e3 mission landed some 12 days after being launched atop a Chinesedeveloped Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13:00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球車) in Shanghai a few years ago it's a wonderful technological achievement to have landed,” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod2, which was kept warm by polonium(釙)210. But the sixwheeled Chinese vehicle carries a more sophisticated payload(復雜的有效負荷), including groundpenetrating radar which will gather measurements of the lunar soil and crust.
【小題1】What does the text mainly talk about?
A.China's space and aeronautics industry develops quickly. |
B.The importance of China's space and aeronautics industry. |
C.China's Jade Rabbit Moon rover sends back first photos. |
D.Chang'e3 is the third unmanned rover mission to touch down on the lunar surface. |
A.nearly 40 | B.37 |
C.64 | D.more than 40 |
A.do some research about the moon |
B.be the first settler on the moon |
C.to plant the Chinese flag onto the moon |
D.send a lovely jade rabbit onto the moon |
A.13:00 | B.20:00 |

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(喜馬拉雅山地區(qū))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(類人猿似的)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(證據(jù))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.
【小題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.a(chǎn)ll the big foot discovered have the same look |
A.1999 | B.the 1960’s |
C.the 1950’s | D.the 1940’s |
A.may fool the world into believing |
B.have definite evidences to prove |

The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference (電磁干擾). The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.
RTC.A. an organization which advises the aviation (航空 )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights .Cur- rently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are un- willing to carry out a total ban, given that many passengers want to work during flight.
The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.
The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.
【小題1】What is said about the over 100 aircraft incidents in the past 16 years?
A.They may have been caused by the damage to-the radio systems. |
B.They may have taken place during take-off and landing. |
C.They were proved to have been caused by the passengers portable computers. |
D.They were suspected to have resulted from electromagnetic interference. |
A.Because it is extremely dangerous to conduct such research on an airplane. |
B.Because it remains a mystery what wavelengths are liable to be interfered with. |
C.Because research scientists have not been able to produce the same effects in labs. |
D.Because experts lack adequate equipment to do such research. |
A.they don't believe there is such a danger as radio interference |
B.the harmful effect of electromagnetic interference is yet to be proved |
C.most passengers refused to take a plane ,which bans the use of radio and cassette players |
D.they have other effective safety measures to fall back on |
A.a(chǎn) new rule for all airlines |
B.the disadvantages of electronic devices |
C.a(chǎn) possible cause of aircraft incidents |
D.effective safety measures for air flight |

Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.
We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生學) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(檔案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(簡單抽象藝術(shù)) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(螞蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.
【小題1】“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.
A.they are highly-evolved species as humans |
B.a(chǎn)nimals have skills that humans do not possess |
C.humans can learn animals’ skills |
D.they are skillful in different ways |
A.People carried out a systematic study on pigeons. |
B.People studied more animals and plants to develop the airplane. |
C.People could fly their airplane for fun. |
D.People kept their airplane at a French gallery. |
A.It has cost a large sum of money. |
B.It has changed our life. |
C.It has improved the abilities of tanks |
D.It has not succeeded yet. |
A.many inventions get ideas from nature. |
B.Some animals possess unique skills. |
C.People should protect nature. |
D.Bionics is far from perfect |

Our body clock,or natural body rhythm,influences our energy and alertness.Paying attention to it can help us choose the suitable time of day when we best perform specific tasks.
The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society.
But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor.
When the body clock can synchronize(使……同步)the rhythms of its natural processes,it “gives us an advantage in daily life”,says Key.
According to him,when it comes to cognitive(認知的)work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve.
However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted(分心)between noon and 4 pm.
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap.
Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.
When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering.
Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans.
【小題1】If we know our natural body rhythm well, we can .
A.find out the suitable time to do specific tasks |
B.organize our time around work demands |
C.do whatever our body feels like doing |
D.be sure to be healthy |
A.Our alertness is influenced by our natural body rhythm |
B.Doing whatever your body feels like is very difficult in our modem society. |
C.Obeying our body clock is good for our health. |
D.Disrupting our natural body rhythm can lead to obesity. |
A.When our body clock synchronizes the rhythms of its natural processes,we can do better. |
B.When it comes to cognitive(認知的)work,most people perform best in the late morning. |
C.As body temperature rises before awakening in the morning,our concentration gradually improves. |
D.We concentrate better in the late morning than between noon and 4 pm. |
A.when we get up in the morning |
B.when we are tired in the evening |
C.when we are full of energy in the late morning |
D.when we are asleep at night |
A.What is natural body rhythm? |
B.Natural body rhythm is good for us. |
C.Something about natural body rhythm. |
D.The latest research about natural body rhythm. |
