evidence of life.
" Sharp new images received from their Phoenix lander convinced scientists that the
spacecraft " s thrusters (推进器) had uncovered a large patch of ice just below the Martian
surface, " team members said.
That bodes (预示) well for the mission " s main goal of digging for ice that can be tested
for evidence of organic compounds that are the chemical building blocks of life.
Washington University scientist Ray Arvidson said the spacecraft" s thrusters may have blown
away dirt covering the ice when the robot landed one week ago.
Scientists said a detailed image taken under the lander shows one of the craft"s three legs
sitting on rough dirt and a large patch of what appears to be ice-possibly 3 feet(0. 9 metres) in
diameter(直径) -that apparently had been covered by a thin layer of dirt.
" We were worried that it may be 30-,40-,50-centimeter deep, which would be a lot of
work. Now we are fairly certain that we can easily get down to the ice table, " said Peter Smith,
a University of Arizona scientist who is in charge of the project.
The spacecraft is equipped with a shovel-like robot arm that will be used to dig into the ground
and collect samples for testing in the lander"s small laboratories.
The lander was sent to a spot on Mars" northern regions in hopes of finding frozen water, but
just how deep underground it would be found was unknown.
The robot arm is expected to begin its first digging operations after several more days of testing.
Once the arm starts digging, dirt and ice it scoops up will be deposited(存放 ) in several small
ovens to be heated. Measuring devices will test the resulting gases.
The University of Arizona in Tucson is leading and NASA"s Jet Propulsion Laboratory is managing
the three-month scientific mission.
B. To explore life in outer space.
C. To study the minerals in the soil.
D. To discover new resources in outer space.
B. Because it takes some time to deal with the large patch of ice.
C. Because it" s impossible for Phoenix lander to collect the ice.
D. Because it"s hard to carry the ice back to laboratories on the earth .
B. The ice table
C. The robot arm
D. The Phoenix lander
B. The goal of sending Phoenix lander to Mars is to look for frozen water.
C. The goal of sending Phoenix Iander to Mars is to discover new resources.
D. It takes some time to deal with the large patch of ice for Phoenix lander.

same independent exam -- besides the national one -- to test students hoping to gain entrance to them in
2011.
The seven are Peking University, Beihang University, Beijing Normal University, Nankai University,
Fudan University, Xiamen University and Hong Kong University.
Students who want to gain entrance to any of the seven universities will only have to sit one independent
exam, according to the joint announcement.
"This will help lighten tile students" load, otherwise they must take several exams for different universities," said the announcement.
Passing the exam could result in more than one interview chance, giving the students more opportunities to choose their favorite universities.
China"s college entrance exam system is undergoing reform as universities aim to select students based
on independent criteria rather than just using the results of the national exam.
In 2003, Peking University and another 21 universities were allowed to pilot (试用) the reform by
using their own criteria to independently select five percent of their students.
Now nearly 80 universities across the country have the right to select talented students based on their
own exams.
