Scientists announced on Thursday, February 11, 2016, at a press conference in Washington, D. C that the more than half-century search for gravitational waves finally succeeded. They confirmed that they had detected gravitational waves caused by two black holes mixing together about 1. 3 billion years ago. It had been the first time the phenomenon was directly detected since it was predicted by Albert Einstein l00 years ago.
A China led space gravitational wave detection project is recruiting (招募) researchers from around the world, china news, com reported. The Tianqin project was started by Sun Yat-sen University in Zhuhhai. It centers on research of key technologies in space gravitational wave detection. To make the project more competitive,global talents in areas such as gravity theory,space gravity experiments and precision measurement are sought with an annual salary of up to 1 million yuan ($ 153.000). according to the report.
Gravitational waves are not easily detectable. When they reach the Earth, an extremely sensitive detector is needed, as other sources of noise can overwhelm the signal. Luo Jun. president of Sun Yat sen University said the detection of gravitational waves is a huge challenge and the project reflects the research competence of China.
The 15-billion yuan project aims to send wave-detection satellites into space in 15 to 20 years with construction of a research center and observatory to be started soon. Researchers will likely cooperate with other scientists from the European Space Agency’s LISA Project.
Gravitational waves are ripples (涟漪) in space time generated during the earliest moment of the universe, when the universe experienced a brief but disordered period of expansion. The detection of gravitational waves is believed to help scientists understand more mysteries of the universe.
1.What can we learn about gravitational waves?
A. They caused black holes to mix together.
B. They came out about half a century ago.
C. They wore proved true by Albert Einstein.
D. They have been discovered recently.
2.According to the passage, the Tianqin project is intended to .

On a visit to Sussex on February 16th, David Cameron announced that, if the Conservatives win the election on May 7th, young people who are out of work, education or training for six months will have to do unpaid community work to get benefits. The speech was part of a pre-election push to show the Conservative Party is tough on welfare reform (though critics insist such schemes rarely promote employment). “The well-worn path—from the school gate down to the job centre and on to a life on benefits—has got to be wiped away,” said the prime minister.
The welfare bill has fallen a bit as unemployment drops. But the main attempt to reform working-age benefits—known as universal credit (UC)—has gone away. In 2011 Mr Cameron said it would be part of “the most ambitious and fundamental changes to the welfare system since it began”. The latest stage of UC was also started from February 16th, but its future is not certain at all.
UC combines six working-age benefits, including tax credits, housing benefit and job-seeker’s allowance, into a single payment. It aims to provide the poorest Britons with a ladder to climb out of welfare dependency by simplifying a system that provides perverse incentives(反常动力) to stay on benefits rather than work. Its champion, Iain Duncan Smith, the secretary for work and pensions, claims it is as much about changing culture as about saving money.
The project has crawled along, hitting many obstacles on the way, such as an overly ambitious timetable that had to be reset in 2013 and an IT system that had to be abandoned, costing tens of millions of pounds. Mr Duncan Smith debated often with George Osborne, the harder-nosed chancellor of the exchequer(财政大臣).
Other problems have come from technical complexities, such as linking the tax system’s computers with those at the department for work and pensions. Critics say that moving all claims online is foolish when many people do not even have access to a computer. Similarly foolish, they say, are plans to pay benefits monthly rather than weekly to people who cannot budget, and to give housing benefit to applicants who may waste it rather than directly to the landlords of their government-funded housing. Defenders say the poor need to be given more responsibility. “The current benefits system is just ‘process and pay’,” says Christian Guy, Mr Duncan Smith’s former speechwriter, now head of the Centre for Social Justice. “UC makes the assumption of ambition.”
This week’s limited demonstration will mean that 250 job centres—roughly one in three—will offer UC. But these numbers refer to a system used for single recipients with no dependents. The bigger “digital” system, covering complex applicants with children, has not yet been tested. “The reason this week’s announcement means nothing is that we are still not sure if the system works for most people,” says Jonathan Portes of the National Institute of Economic and Social Research. “They’re producing a system they are not going to use.” The government hoped that 1 million people would be using UC by April 2014, but only 64,000 have used it so far.
There is no guarantee it will be carried out in full, even if the Tories form the next government. “I wouldn’t put money on UC continuing under either major party,” says Colin Talbot of the University of Manchester. Opponents say gains will be the lowest. They accuse Mr Duncan Smith and his team of trying to change the world. Mr Guy contradicts: “At least someone is trying.”

The world's first luxury space hotel,Aurora Station,was announced Thursday at the Space 2.0 Summit in San Jose,California.Developed by US-based space technology start-up Orion Span,the space station will host six people at a time,including two crew members,for 12-day trips of space travel.It plans to welcome its first guests in 2022.
“Our goal is to make space accessible to all,"Frank Bunger,CEO and founder of Orion Span,said in a statement."Upon launch,Aurora Station goes into service immediately,bringing travelers into space quickly and at a lower price point than ever seen before."
While a$10 million trip is outside the budget of most people's two-week vacations,Orion Span claims to offer an authentic astronaut experience."It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months,at a fraction(小部分)of the cost,"says Bunger.During their 12-day adventure,the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit,where they will witness incredible views of the blue planet.The hotel will orbit Earth every 90 minutes,which means guests will see around 16 sunrises and sunsets every 24 hours.
Activities on board include taking part in research experiments such as growing food while in orbit,which guests can take home for a super-smug souvenir,and soaring over their hometown.Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and,upon(return to Earth will be greeted with a specially arranged hero's welcome.While enjoying the thrills of zero gravity,the travelers will be able to float freely through the hotel,taking in views of the northern and southern aurora from the station's windows.
Deposits are already being accepted for future stays on the space hotel.

The 2016 Nobel Prize in Physics is shared by three scientists, the Royal Academy of Sciences announced in Stockholm on Tuesday. The Nobel Prize in Physics 2016 was divided, with one half awarded to David J. Thouless, the other half to F. Duncan M. Haldane and J. Michael Kosterlitz “for theoretical discoveries of topological phase transitions and topological phases of matter(物质拓扑相变和拓扑相).”
Haldane said he was “very surprised” at the news, adding that he was glad that their discoveries found something previously unnoticed by many, and that they revealed “more possibilities for looking for new materials.” He particularly pointed out that a lot of work was still ongoing.
The year’s prize amount is 8 million Swedish krona(0.93 million US dollars), and will be split properly between the three winners.
The winners are given a sum of money when they receive their prizes, in the form of a document confirming the amount awarded. The amount of prize money depends upon how much money the Nobel Foundation can award each year. The purse has increased since the 1980s, when the prize money was 880,000 SEK per prize. In 2009, the monetary award was 10 million SEK (US$1.4 million; €950,000). In June 2012, it was lowered to 8 million SEK.
If there are two winners of a particular prize, the award money is divided equally between the winners. If there are three, the awarding committee can choose to divide the money equally, or award one-half to one winner and one-quarter to each of the others. It is common for winners to donate prize money to benefit scientific, cultural, or charities.
1.How much price money does Thouless get?
A. 8 million Swedish krona.
B. 6 million Swedish krona.
C. 4 million Swedish krona.
D. 2 million Swedish krona.
2.According to the passage, Haldane thought that his work_________
A. was far from ending
B. was based on many previous studies
C. had perfectly been completed
D. had surprised the whole world
3.The amount of prize money _________. .
A. has been ever increasing since the 1980s
B. has been ever decreasing since the 1980s
C. remains 880,000 SEK each year after 2012
D. differs according to the Nobel Foundation’s affordability
4.What does the last paragraph talk about?
A. The purpose of the award money.
B. How the award money is dealt with.
C. How the laureates are selected.
D. The number of laureates per prize.

Are we alone in the universe? A team of scientists announced on January 6, 2015 that they had identified eight planets beyond our solar system, three or four of which orbit in their stars’ “Goldilocks Zone” --- the region where temperatures are not too hot or too cold for water, which is a necessary ingredient for life as we know it, to exist liquid form.This may be good news for people hoping that Earth is not the only inhabited world in the universe.
The scientists, led by Dr. Guilermo Torres of the Harvard-Smithsonian Center for Astrophysics, made the discoveries using data collected by the planet-seeking Kepler telescope.
NASA launched Kepler in 2009. Since then, the telescope has identified more than 1,000 planets outside of our solar system. Torres and his team analyzed the data about the eight newly discovered world to determine which ones are most likely to be similar to our Earth.
Among the new discoveries, the scientists say the planets called Kepler438b and 442b are the closest to Earth. Kepler 438b is just about 10% larger than our planet, and gets 40% more of its energy from its star than Earth receives from the Sun. Temperatures there would be about 140 degrees. Kepler 442b is about 33% larger than Earth, but receives 30% less energy from its star. That would make it a potentially chillier world than our own.Torres says it is possible for life to exist and survive in either of those temperatures, but for that to happen, these planets would need to have another key ingredient for life: a heat-trapping atmosphere like Earth’s.
While these findings add to the possibility that life exists beyond Earth, Torres cautions against drawing conclusions, “We are not claiming they are inhabited,” he says. In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unknown whether these planets contain life. But the discovery of planets in their stars’ habitable zones suggests that somewhere out there, some form of alien life may have taken hold.
1.The scientists have identified eight planets, .
A. which are suitable for humans to live on
B. some of which are possible for life to exist on
C. some of which have the same situations as Earth
D. which are not too hot or too cold for water to exist on
2.Which statement about the discovery of Torres and his team is TRUE?
A. Kepler 438b is too hot for any life to exist on
B. Kepler 438b and 442b are the farthest to Earth
C. They have made the discoveries through Kepler
D. They have discovered over 1000 planets in 7 years
3.What is the possible thing that Kepler 442b lacks for life to exist on?
A. The water B. The sunlight
C. The soil D. The atmosphere
4.About their exploration, Torres wants to indicate that .
A. there is a lot left to learn
B. they have had decisive gains
C. it is the first in human history
D. it is certain for life on the planets
5.Which can be the best title for this passage?
A. Are We Alone?
B. Eye on the Stars
C. Discover Another Earth
D. Discovery of New Stars to Live on
