听力原文： What is the shape of the universe？ The question has baffled and obsessed humankind since civilization first gazed up towards the heavens. The world has yet to receive a satisfactory explanation. Now a new study hints at a possible answer. Contrary to the traditional interpretation, the study suggests the universe is finite and bears a rough resemblance to a soccer ball, or to put it more accurately, the universe looks like a 12-sided volume bounded by pentagons. Based on the new theory, a model has been made to help illustrate the alleged shape of the Universe. If proven by further evidence and inspection, the model would represent a major discovery about the nature of the cosmos.
"What makes the discovery exciting now is it's not a matter of idle speculation," said Jeffrey Weeks, a US mathematician, "There's real data to look at and there's the great possibility of getting a definite answer." Weeks has announced hints that the Universe is actually relatively small, with a hall-of-mirrors illusion which tricks us into thinking that the space stretches on forever.
While studying cosmic background radiation observed by NASA's Wilkinson Microwave Anisotropy Probe, Jeffrey Weeks, together with a team of French cosmologists, arrived at this new discovery. It is still in question whether the theory is correct. However, the idea itself is indeed appealing and inspiring.

A．A new discovery in Mathematics.
B．A new program conducted by NASA.
C．A new theory on the shape of the universe.
D．A new planet detected in space.

Travel to Moon
The National Aeronautics and Space Administration (NASA) has announced plans to return people to the moon by 2018. "And this time," according to a NASA press release, “we&39;re going to stay."＜br＞
NASA wants to make a new spaceship for the missions using parts from the Apollo program,which first took people to the moon in 1969, and the space shuttle. NASA says the new Crew Exploration Vehicle (CEV) will be "affordable, reliable, and safe".＜br＞
The CEV will be able to hold four astronauts. The plan is to have the CEV dock (对接) in space with the lunar- the vehicle astronauts will use to land on the moon- which will be launched separately into space. The CEV will then travel to the moon and all four astronauts will walk on the moon.＜br＞
The first m, oon missions are expected to last up to seven days. Exploration and construction of a moon base will be the astronauts&39; top priorities (最优先考虑的事). NASA hopes to have a minimum of two moon missions a year starting in 2018. This will allow for quick moon base construction, constant scientific study, and training for future missions to Mars.
What is new in NASA‘s plan to return to the moon by 2018？ 查看材料
A.People will land find remain on the moon
B.Equipment will be carded and installed there
C.More CEVs will be made regularly
D.A special device will be used in landing

U.S. Scientists Confirm Water on Mars
NASA scientists said that Mars was covered once by vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life.
Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples.
"We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "This is the first time Martian water has been touched and tasted. "
The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.
The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday's sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle.
"Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We're excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected, from all the Mars simulation testing we've done so far. "
Since landing on May 25, Phoenix has been studying soil with. a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. The science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present.
The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead.
"It's a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.
A full-circle, color panorama of Phoenix's surroundings also has been completed by the spacecraft.
"The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of Texas A & M University, lead scientist for Phoenix's Surface Stereo Imager camera. "They help us plan measurements we're making within reach of the robotic arm and interpret those measurements on a wider scale. "
What was discovered by NASA's Phoenix Mars Lander on Mars？
A．Vast lakes.
B．Flowing rivers.
C．Water in a soil sample.
D．Living things.

听力原文： Rich Americans are willing to spend large sums of money on space tourism, according to a poll released recently. Possibly bored by the ordinary daily life on earth or inspired by the exciting heroic deeds of such pioneers as first American in space Alan Shepard and first millionaire in space Dennis Tito, the poll says 7 percent of rich Americans would pay $ 20 million for a two-week orbital flight and 19 percent would pay $100,000 for a 15-rninute suborbital flight. The poll by Zogby International was commissioned by Futron Corp. , a Maryland aerospace consulting group which has a $1.8 million contract with NASA to explore the commercial applications of space travel, including what space tourism could look like in the next 20 years. Zoghy International conducted telephone interviews with 450 Americans whose yearly incomes were more than $ 250,000 or whose net worth was more than $1 million. Futron's NASA project program manager Derek Webber said, "We commissioned this survey in order to get an idea of what rich people think and not the man in the street who loves the idea of going into space but can't afford it."

A．Not all Americans can afford traveling in space.
B．Not all Americans think it a good idea to go into space.
C．Most Americans regard space tourism ridiculous.
D．Rich Americans are willing to pay a lot to fly into space.
