Estimates of places where life can exist have been based on the possibility of them having surface water. But software recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by heat from planets.
Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation. On the other hand, planets located in distant reaches from their star have their surface water locked away as ice.
Sean McMahon, who is carrying out the work, explained: "Traditionally people have said that if a planet is in this Goldilocks zone—not too hot and not too cold—then it can have liquid water on its surface and be habitable."
But this concept might change when considering that planets can receive two sources of heat—heat direct from the star and heat generated deep inside the planet.
It is easy to observe it in our own planet. As you go down through the crust (壳) of the Earth, the temperature gets higher and higher. Even when the surface is frozen, water can exist below ground.
There could be immense quantities of water in fact—full of primitive life.
Professor John Parnell, also from Aberdeen University said: "There is a significant habitat for microorganisms below the surface of the Earth, extending down several kilometres".
"And some believe that the majority of life on Earth could even reside in this deep biosphere."
So the Aberdeen team are developing models to predict which distant planets might harbour underground reservoirs of liquid water with the possibility of alien life.

Citing secret documents provided by Edward Snowden, former NSA staff, the reports detail efforts to gain data collection from cell phone carriers and smart phones by tapping into “leaky”(有漏洞的) apps themselves.
Both spy agencies showed a particular interest in Google Maps, which is accurate to within a few yards or better in some locations and would clearly pass along data about the area where phone owner is.
“It effectively means that anyone using Google Maps on a smartphone is working in support of a GCHQ system,” reads a secret 2008 report by the NSA"s sister spy agency, according to the New York Times.
More surprising is the wide range of apps that the agencies search for data, including innocent-seeming apps such as Angry Birds. One document in particular from GCHQ listed what information can be found from which apps, mentioning Android apps but suggesting the same data was available from the iPhone platform.
Angry Birds maker Rovio Entertainment of Finland said it had no knowledge of any NSA or GCHQ programs for tapping into its users’ data.
"Rovio doesn"t have any previous knowledge of this matter, and have not been aware of such activity in 3rd party advertising networks," said Saara Bergstrom. "Nor do we have any involvement with the organizations you mentioned."
Mobile photos uploaded to social media sites like Facebook and Twitter appear to be a particularly rich source of information for the spy agencies as well. Metadata in the photos is briefly available. The NSA and GCHQ are able to tap into that metadata to collect a wealth of key data points about a person’s life.
“NSA does not profile everyday Americans as it carries out its foreign intelligence mission,” the agency told the Times in response to questions about the program.
During a Monday press conference, White House press secretary Jay Carney stressed that same position. "As the president said in his Jan. 17 speech, to the extent data is collected by the NSA, through whatever means, we are not interested in the communications of people who are not valid foreign intelligence targets（情报目标） and we are not after the information of ordinary Americans," he said.
小题1:American and British spy agencies were both particularly interested in the information gathered from_________.
| A．Google Maps | B．Twitter | C．Angry Birds | D．Facebook |
| A．The iPhone platform is more reliable than that of Android. |
| B．The New York Times interviewed Edward Snowden secretly. |
| C．It is difficult for common users to protect their personal information. |
| D．A document from NSA listed what information can be found from which apps. |
| A．NSA didn’t gather any worthy information from Americans. |
| B．NSA would stop its foreign intelligence mission in the future. |
| C．NSA and White House shared different attitude towards the affair. |
| D．NSA collected information with the permission of White House |
| A．Angry Birds Give You Away |
| B．NSA Gather Information from Apps |
| C．Reports from the New York Times |
| D．Documents from Edward Snowden |
Until now the local government has only been prepared to provide bus services for children living more than three miles from their school, or sometimes less if special reasons existed. Now it has been decided that if a group of parents ask for help in organizing transport they will be prepared to go ahead, as long as the arrangement will not lose money and children taking part will be attending their nearest school.
The new plan is to be tried out this term for children living at Milton who attend Impington School. The children live just within the three-mile limit and the local government said in the past that they would not undertake (agree) to provide free transport to the school. But now they have agreed to offer a sum of money for a bus service from Milton to Impington and back, a plan which has the support of the school’s headmaster.
Between 50 and 60 parents have said they would like their children to take part. Final calculations have still to be carried out, but a government official has said the cost to parents should be less than ￡20 a term. They have been able to arrange the service at a low cost because there is already an agreement with the bus company for a bus to take children who live further away to Impington. The same bus would now just make one more journey to pick up the Milton children. The official said they would get in touch with other groups of parents who in the past had asked if transport could be provided for their children, to see if they would like to take part in the new plan.
小题1:What is the aim of the plan?
| A．To prevent the students’ road accidents. |
| B．To relieve the traffic pressure. |
| C．To save time for the parents and students. |
| D．To help the parents save money. |
| A．By letting the bus run in the morning only. |
| B．By limiting the number of the students. |
| C．By getting the support from the headmaster. |
| D．By linking the new bus service with the existing one. |
| A．The bus company will make much more money. |
| B．The children can choose whatever school they like. |
| C．The parents can get rid of their worries. |
| D．The students in Impington School can have free bus rides. |
| A．a personal letter | B．an advertisement |
| C．a headmaster’s report | D．a newspaper article |
There were no reports of bad weather and no sign of why the Boeing 777-200ER would have vanished from radar screens about an hour after it took off from Kuala Lumpur for Beijing.
“We are not ruling out any possibilities,” Malaysia Airlines CEO Ahmad Jauhari Yahya told a news conference.
By the early hours of Sunday, there were no confirmed signs of the plane or any wreckage, well over 24 hours after it went missing. Operations will continue through the night, officials said.
There were no indications of sabotage (蓄意破坏) nor claims of an attack. But the passenger list issued by the airline included the names of two Europeans—Austrian Christian Kozel and Italian Luigi Maraldi—who, according to their foreign ministries, were not in fact on the plane.
A foreign ministry spokesman in Vienna said: “Our embassy got the information that there was an Austrian on board. That was the passenger list from Malaysia Airlines. Our system came back with a note that this is a stolen passport.”
Austrian police had found the man safe at home. The passport was stolen two years ago while he was travelling in Thailand, the spokesman said.
The foreign ministry in Rome said no Italian was on the plane either, despite the inclusion of Maraldi’s name on the list. His mother, Renata Lucchi, told Reuters his passport was lost, presumed stolen, in Thailand in 2013.
U.S. and European security officials said that there was no proof of any terrorist link and there could be other explanations for the use of stolen passports.
小题1:What was Ahmad Jauhari Yahya’s attitude?
| A．Uncertain. | B．Negative. | C．Positive. | D．Confident. |
| A．two passports had been stolen by two Europeans |
| B．Christian Kozel was the man who kidnapped the plane |
| C．the Austrian on board was actually at home |
| D．Christian Kozel lied to the police |
| A．He was from Austria. |
| B．He was found safe at home. |
| C．His mother was sad when she saw his name on the list. |
| D．His passport was lost in Thailand. |
| A．Terrorists. | B．Two people using false identities. |
| C．We are not sure. | D．Christian Kozel and Luigi Maraldi. |
Day turned into night. Temperature turned cooler in cities and villages filled with fans of astronomy. The total eclipse could be seen starting in India on Wednesday morning and moving eastward across China and parts of the Pacific. Millions cast their eyes towards the heavens to catch an unusual view of the sun’s colorful ring. Cloud in some areas prevented people from fully enjoying the sight. Still, many were frightened.
The total eclipse occurs about twice a year as the moon passes between the earth and the sun on the same plane as earth’s circle.
The local astronomy society gave a flash on how an eclipse happens. Wednesday’s event lasted up to more than six minutes in some places. In India, thousands bathed in the Ganges River in the Hindu holy city of Varanasi to clean their souls. It was sunny sky in Hong Kong for the eclipse, where students, parents and the elderly flooded in a primary school to watch.
In Shanghai, children climbed up ladders to look through two large telescopes on the school roof to catch sight of the moon moving across the sun. Others looked through a pair of glasses covered with solar filter (过滤器) paper, where they could take pictures of the moon moving over the sun.
In some cultures, many old stories are about eclipse. In India, a eclipse was considered unfavorable. In Chinese tradition, there is a story about a heavenly dog eating the sun. As the story goes, people would make noise to frighten off the dog and save the sun.
小题1:What can we learn about the longest solar eclipse of the century?
| A．Not everyone in the world could see the longest eclipse. |
| B．Any of the Asians was excited to watch the eclipse. |
| C．All people saw the longest solar eclipse on Wednesday. |
| D．The Chinese all caught sight of the total eclipse at the same time. |
| A．All people watched the solar eclipse for at least six minutes. |
| B．In ancient China, people couldn’t understand this phenomenon. |
| C．Your eyes must be hurt without filter equipment while watching. |
| D．You can watch the total solar eclipse directly only with your eyes. |
| A．Most Chinese people used to think eclipses would bring about misfortunes. |
| B．Chinese fathers were pleased to watch solar eclipses. |
| C．Indians think bad fortune will come about along with eclipses. |
| D．The Chinese people are too frightened to go outside when eclipses occur. |
| A．In Shanghai. | B．In India. | C．In Hong Kong. | D．In the Pacific Ocean. |
This is not a surprise to public health advocates.They"ve studied the effect of state tax increases for years，finding that smokers，especially teens，are price sensitive.Nor is it a shock to the industry，which fiercely fights every tax increase.
The only wonder is that so many states insist on closing their ears to the message.Tobacco taxes improve public health，they raise money and most particularly，they deter people from taking up the habit as teens，which is when nearly all smokers are addicted.Yet the rate of taxation varies widely.
In Manhattan，for instance，which has the highest tax in the nation，a pack of Marlboro Light Kings，cost $10.06 at one drugstore Wednesday.In Charleston，S.C.，where the 7 cent a pack tax is the lowest in the nation，the price was $4.78.
The influence is obvious.
In New York，high school smoking hit a new low in the latest surveys－13.8%，far below the national average.By comparison,26% of high school students smoke in Kentucky.Other low tax states have similarly depressing teen smoking records.
Hal Rogers，Representative from Kentucky，like those who are against high tobacco taxes，argues that the burden of the tax falls on lowincome Americans “who choose to smoke.”
That"s true.But there is more reason in keeping future generations of lowincome workers from getting hooked in the first place.As for today"s adults，if the new tax drives them to quit，they will have more to spend on their families，cut their risk of cancer and heart disease and feel better.
小题1:The text is mainly about ________.
| A．the price of cigarettes |
| B．the rate of teen smoking |
| C．the effect of tobacco tax increase |
| D．the differences in tobacco tax rate |
| A．The new tax will be beneficial in the long run. |
| B．Lowincome Americans are more likely to fall ill. |
| C．Future generations will be hooked on smoking. |
| D．Adults will depend more on their families. |
| A．tolerance | B．unconcern |
| C．doubt | D．sympathy |
| A．Teen smokers are price sensitive. |
| B．Some states still keep the tobacco tax low. |
| C．Tobacco taxes improve public health. |
| D．Tobacco industry fiercely fights the tax rise. |
