“iPhone 5”, the tallest thing to happen to iPhone since iPhone
We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (顯示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快門). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!

DNA left at a crime scene could be used in the future to build up a picture of an offender’s face, it was revealed tonight.
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突變) that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.
【小題1】The underlined word “mugshots” in the second paragraph most probably means _________.
A.different faces | B.characteristics | C.pictures of faces | D.genders |
A.they can merely match to an individual or identify an individual |
B.there is a possibility of going from DNA to a face |
C.DNA could be used to produce a rough image of an offender’s face |
D.this technology is more reliable than computer-generated “e-fits” |

Farmers, especially in developing countries, are often criticized for cutting down forests. But a new study suggests that many farmers recognize the value of keeping trees.
Researchers using satellite images found at least ten percent tree cover on more than one billion hectares of farmland. That is almost half the farmland in the world. Earlier estimates were much lower but incomplete. The authors of the new study say it may still underestimate the true extent worldwide.
The study found the most tree cover in South America. Next comes Africa south of the Sahara, followed by Southeast Asia. North Africa and West Asia have the least.
The study found that climate conditions alone could not explain the amount of tree cover in different areas. Nor could the size of nearby populations, meaning people and trees can live together. There are areas with few trees but also few people, and areas with many trees and many people. The findings suggest that things like land rights, markets or government policies can influence tree planting and protection.
Dennis Garrity, who heads the World Agroforestry Center, says farmers are acting on their own to protect and plant trees. The problem, he says, is that policy makers and planners have been slow to recognize this and to support such efforts.
The satellite images may not show what the farmers are using the trees for, but trees provide nuts, fruit, wood and other products. They also help prevent soil loss and protect water supplies. Even under drought(干旱)conditions, trees can often provide food and a way to earn money until the next growing season.
Some trees act as natural fertilizers. They take nitrogen(氮?dú)?out of the air and put it in the soil. Scientists at the Center say the use of fertilizer trees can re-duce the need for chemical nitrogen by up to three-fourths. Trees also capture carbon dioxide, a gas linked to climate change.
【小題1】Through the study, the researchers found that .
A.there are more trees on farmlands than expected |
B.fewer trees are being cut in developing countries |
C.most farmers still don’t realize the value of trees |
D.trees play a key role in preventing climate change |
A.Southeast Asia | B.West Asia. |
C.South America. | D.Africa south of the Sahara. |
A.most farmers care about nothing but their own interests |
B.there are usually few people living in areas with few trees |
C.government plays a small role in tree planting and protection |
D.government should support farmers in planting and protecting trees |
A.how farmers plant trees |
B.what products trees can bring |
C.the importance of trees to farmers |
D.the environmental value of tree cover |

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 meters lies a natural aquifer (蓄水層) into which several heat exchangers (交換器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
【小題1】Which of the following is TRUE according to the first two paragraphs?
A.Arian de Bondt got his idea from his boss. |
B.Large, flat, black surfaces need to be built in cities. |
C.Heat can also be collected from asphalt roads. |
D.The Dutch engineer's system has been widely used. |
A.To absorb heat from the sun. |
B.To store heat for future use. |
C.To turn solar energy into heat energy. |
D.To carry heat down below the surface. |
A.the system can do more than warming up the building |
B.some pipes have to be re-arranged in winter |
C.the exchangers will pick up heat from the street surface |
D.less heat may be collected in winter than in summer |
A.What we shall do if the system goes wrong. |
B.What we shall do if there are no asphalt roads. |
C.How the system cools the building in summer. |
D.How the system collects heat in spring and autumn. |

How the Grand Canyon (大峽谷) was created remains one of the geology’s greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.
Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤壩) bursts.
Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔巖) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon.
Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers.
The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.
The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.
【小題1】In the past, deep canyons were believed to have formed _______.
A.a(chǎn)s a result of a sudden break of volcanoes |
B.due to river flows over millions of years |
C.owing to the burst of artificial dams |
D.thanks to our ancestors’ creative work |
A.Several volcanoes broke out on Mars directly creating grand canyons. |
B.Several great lakes existed on the upper parts of the Colorado River. |
C.People built high dams on the upper parts of the Colorado River. |
D.The Colorado River crossed the Grand Canyon to form down-cutting. |
A.there are great lakes on Mars |
B.there are active volcanoes on Mars |
C.there might be cities on Mars |
D.there might be life on Mars |
A.Lakes on Earth and Mars |

Hello! My name is Lisa, and I am a lioness. I live on the open grasslands of Africa with my family. Lions living in a group are called a pride.
My father is strong and powerful. He and his cousin are the leaders of our pride. The other members are my mother, her sisters, and their children.
The area where a pride lives is big! We roar (咆哮) to tell each other where we are and to warn strangers to stay away.
Meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped (有條紋的). As we grow older, the spots gradually disappear.
Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He’ll run around with a male (雄性的) friend or relative for a few years until they take over a pride of their own.
But for now, we have lots of fun together. We often play and fight for hours, which can help us practice skills that we will need for hunting.
We lions keep ourselves very clean. Just like a house cat, I clean my fur (毛) with my tongue. We clean for each other, too, to show we’re friends.
Lions like to sleep for most of the day. We hunt in the cool evening. Female (雌性的) lions hunt more often than male lions. We work together as a team. At the right moment, we attack and kill our prey. Then we share it. Male lions usually eat first. Females eat next. Baby lions are the last to eat. The smallest one gets the least food.
Since we are full, it’s time to go to find a nice place for a sleep. Bye!
【小題1】According to the passage, Leon _____.
A.hunts more often than his sisters |
B.will have spots on his fur for the whole of his life |
C.will leave his birth pride when he is about three |
D.will take over his birth pride when his father dies |
A.the animal that is hunted |
B.the animal that is dangerous |
C.the animal that is powerful |
D.the animal that is ill |
A.Lions sometimes clean their fur for each other. |

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world?It’s an increasingly urgent question,given the recent highprofile(引人注目的) mining accidents in Sago,W.Va.and Huntington,Utah.A small group of engineers and robotics experts look forward to a day in the nottoodistant future when robots and other technology do most of the dangerous mining work.
Robotic technology,in particular,holds much promise,McAteer says,especially when it comes to mapping mines and rescuing trapped miners—the special operations of the mining industry.
One of the first mining robots was developed five years ago at CarnegieMellon University’s Robotics Institute.It was called Groundhog and it looked like a golf cart.It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler.It’s a bit smaller than Groundhog,and even more advanced.It can take photos and video and has sensors mounted(增加) that can detect the presence of dangerous gases.Incredibly,the robot has a real sense of logic.If it comes across an obstacle it gets confused.It has to think through the process and where to go next,and sometimes it throws_a_fit just like a real person.
The biggest obstacle,though,is cost.The original research project was federally funded,but that money has dried up,and it’s not clear where future funding will come from. Partly for that reason,and partly because of advances in safety,mining is not nearly as dangerous as it was in the past.Since 1990,fatalities(致命性) have declined by 67 percent and injuries by 51 percent,according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.The robots do the most repetitive and dangerous jobs,but don’t eliminate(消除) the need for human workers.
【小題1】The underlined phrase “throws a fit” in Paragraph 4 probably means “________”.
A.gets angry | B.gets sick |
C.becomes hungry | D.becomes cheerful |
A.robots in mines will serve much in the automotive industry |
B.there will be no need for human workers in mines |
C.the mine robots will have a very bright future |
D.robots in mines have a long way to go |
A.Mining robots do most of the mining work at present. |
B.Groundhog can discover the presence of dangerous gases. |
C.Experts are trying to make robots save miners in danger. |
D.Robots cannot do dangerous work in dark areas. |

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陳代謝) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (監(jiān)控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的衛(wèi)星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
【小題1】European researchers are conducting hibernation experiments to ________.
A.ensure astronauts to get a complete sleep |
B.find the secret of some creatures |
C.make preparations for the journey to Jupiter’s moon Callisto |
D.know if man can sleep for years |
A.Science fiction is people’s imagination. |
B.Science fiction is imaginative, but it can be realized. |
C.Things seem impossible may come true. |
D.Things described in science fiction are sure to become true. |
A.putting living cells into a sleep-like state is full of failure |
B.Biggiogera is confident with the experiment |
C.human’s hibernation needs no energy |
D.medical research is the key to space flight hibernation system |
A.Six humans to fly to Callisto |
B.Human hibernation improves health |
C.Space travel attracts people |
D.Deep sleep for deep space travel |
