Batteries are included, but the charger’s not. The Nokia E-Cu concept phone doesn’t need to plug in; it charges from any heat source. Designer Patrick Hyland says it can even work off the warmth of your pocket. The first time“it would take approximately seven hours to reach full charge, then after that it’s continuously charging by keeping the phone in areas between 86 degrees and 104 degrees Fahrenheit. ”That’s one hot pocket.
He’s put a thermo generator(热偶发电器)inside the phone that transforms heat into electric potential energy. To better conduct the heat to that little power plant in your pocket, the E-Cu(E for energy, Cu for copper)is coated by copper backing with heat sinks like those normally used to keep electronics from overheating.
Nokia doesn’t have current plans to build the phone, so for now it remains a concept. But Hyland says he’s open to anyone who wants to cooperate.
For Americans this technology would certainly be convenient. It would also save a bit on energy bills and waste. ”Annually, unwanted phone chargers produce 51, 000 tons of waste in addition to the greenhouse gases created by the production of the electricity needed to charge them, ”Hyland says. So a charger-free phone is also a green phone. Though adapting our plug-in habits would help a group of people, most cell phone related energy use comes from leaving your charger plugged in all day unnecessarily.
The real potential for charger-free cell phone technology is what it could enable places where plugging in isn’t an option, like rural areas in the developing world.
Cell phones are spreading faster than power lines and bringing with them countless opportunities, aid and health advances. A phone like the E-Cu, if it ever comes to be, would enable all manner of expanded aid and development by phone projects. Let’s hope Patrick finds a partner.

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(突变) 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.The underlined word “mugshots” in the second paragraph most probably means _________.
| A．different faces | B．characteristics | C．pictures of faces | D．genders |

The slavery drama “12 Years a Slave” won the Academy Award for best picture on Sunday, making history as the first movie from a black director to win the film industry’s highest honor in 86 years of the Oscars. British director Steve McQueen’s brave portrayal of pre-Civil War American slavery won two other Oscars, including best supporting actress for newcomer Lupita Nyong’o and best adapted screenplay based on the memoir of Solomon Northup, a free man tricked and sold into slavery in Louisiana. “Everyone deserves not just to survive but to live. This is the most important legacy of Solomon Northup,” said McQueen in his acceptance speech.
“12 Years a Slave” was better over space thriller “Gravity” from Mexican filmmaker Alfonso Cuaron, which nevertheless got the most Oscars of the night with seven, including the best director honor for Cuaron, a first for a Latin American director.The film starring Sandra Bullock as an astronaut lost in space swept the technical awards like visual effects and cinematography, a reward for its groundbreaking work on conveying space and weightlessness. Referring to the “transformative” experience he and others undertook in the four-plus years spent making “Gravity”, Cuaron, whose hair is graying, said, “For a lot of these people, that transformation was wisdom. For me, it was just the color of my hair.”
In one of the strongest years for film in recent memory, the 6,000-plus voters of the Academy of Motion Picture Arts and Sciences scattered golden Oscar statuettes among the many acclaimed movies in contention.
It was a good night for the scrappy, low-budget film “Dallas Buyers Club”, directed by Jean-Marc Vallee, a biopic of an early AIDS activist two decades in the making that won three Oscars, including the two male acting awards.
Matthew McConaughey, in a validation of a remarkable career turnaround, won best actor for his portrayal of the homophobe who turned AIDS victim and then turned treatment crusader Ron Woodroof, a role for which he lost 50 pounds (23 kg). His co-star, Jared Leto, won best supporting actor for his role as Woodroof’s unlikely business partner, the transgender woman Rayon, for which he also slimmed down drastically.
Australia’s Cate Blanchett won the best actress Oscar for her acclaimed role as the socialite unhinged by her husband’s financial crimes in Woody Allen’s “Blue Jasmine.” “As random and subjective as this award is, it means a great deal in a year of, yet again, extraordinary performances by women,” said Blanchett, who beat out previous Oscar winners Bullock, Amy Adams, Judi Dench and Meryl Streep.The film which won the largest number of Oscar awards this year is ______.
| A．12 Years a Slave | B．Gravity |
| C．Dallas Buyers Club | D．Blue Jasmine |
Which director spent the least money in making the film?
| A．Steve McQueen. | B．Alfonso Cuaron. |
| C．Jean-Marc Vallee. | D．Woody Allen. |

| C．The character Rayon is played by Jared Leto. |
| D．The woman film star Cate Blanchett comes from Oceania. |
I was now in my twenty third year of residence in this island and was accustomed to the place and to the manner of living. If it had not been the savages（野人）who had come to the place to disturb me, I could have been content to spent the rest of my time there, even to the last moment, till I had laid me down and died, like the old goat in the cave.
I had also arrived to some little recreations and amusements, which made the time pass more pleasantly with me a great deal than it did before．
At first, I had taught my Poll to speak. And he did it so familiarly and talked so clearly and plain that it was very pleasant to me. And he lived with me no less than twenty six years. How long he might live afterwards, I don’t know; though I know they have an idea in Brazil that they live a hundred years. Perhaps poor Poll may be alive there still, calling Poor Robin Crusoe to this day. I wish no other English man had the bad luck to go there and hear him. But if he did, he would certainly believe it was the devil（魔鬼）.
My dog was a very pleasant and loving companion to me, for no less than sixteen years of my time, and then died of mere old age.
As for my cats, they multiplied to that degree that I had to shoot several of them at first to keep them from eating up all I had.
Besides these, I had two more parrots which talked pretty well and would all call Robin Crusoe, but none like my first. Nor indeed did I take the pains with any of them that I had done with him.
I had also several sea-fowls, whose names I don’t know, that I caught upon the shore and cut their wings. And the little stakes which I had planted before my castle wall being now grown up to a good thick bush, these fowls all lived among these low trees and bred there, which was very agreeable to me; so that as I said above, I began to be well content with the life I led if not worried about the threat from the savages.What does the passage mainly talk about?
| A．Robin Crusoe treated animals kindly. |
| B．Robin Crusoe led a hard life on the island. |
| C．The animals raised by Robin Crusoe brought him much pleasure. |
| D．The savages always spoiled Robin Crusoe’s happy life. |
How many parrots did Robin Crusoe mention in this passage?
| A．2 | B．3 | C．4 | D．5 |
According to the passage, which of the following statements is true?
| A．Robin’s dog may be still alive on the island. |
| B．Robin Crusoe lived in harmony with savages. |
| C．Robin Crusoe met an English man while on the island. |
| D．Parrots raised by Robin could talk very well. |
What is the “sea-fowl” mentioned in the last paragraph?
| A．A bird living on the coast. |
| B．A fish living in the sea. |
| C．A creature without a name |
| D．An animal feeding on tree leaves. |
The £109 Nest Protect Smoke Alarm promises Internet alerts（警报）and an end to the low battery chirp（短而尖的叫声）. Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep（嘟嘟声）. And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”For what purpose did Nest create the Protect Smoke Alarm?
| A．To predict low-level fire risks. | B．To experiment with a new battery. |
| C．To improve present smoke alarms. | D．To avoid the low-battery chirp. |
What did Tony Fadell really want to tell us in Paragraph 3?
| A．One of his cooking experiences. |
| B．Disadvantages of present smoke alarms. |
| C．His growing distrust of smoke alarms. |
| D．His source of annoyance to crying wolf. |
Which of the following are the advantages of the Protect Smoke Alarm?
a. Rechargeable batteries b. A talking smoke alarm
c. Longer battery life d. Going off constantly
e. Internet connection
| A．a, b, c | B．c, d, e | C．a, c, e | D．b, c, e |
What can we know from the last paragraph?
| A．In the UK people seldom set up smoke alarms. |
| B．Matt Rogers didn’t like the safety requirements. |
| C．Non-functioning smoke alarms make people annoyed. |
| D．The government should pay attention to safety issues. |
