题文
阅读理解。 NASA scientists said on June 1 , 2008 they had found ice on Mars-a step towards findingevidence 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.1. What was the Phoenix lander meant to do? A. To search for frozen water on Mars.
B. To explore life in outer space.
C. To study the minerals in the soil.
D. To discover new resources in outer space.2. Why did NASA scientists feel worried about the finding? A. Because the ice is too large for NASA scientists to dig up.
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 .3. "The spacecraft" in Paragraph 7 refers to"_______".A. The project
B. The ice table

考点
据考高分专家说，试题“阅读理解。 NASA.....”主要考查你对 [新闻报道类阅读 ]考点的理解。新闻报道类阅读
新闻报道类阅读的概念：
阅读理解的选材明显地呈现出关注实际生活的趋势，这种趋势与当前基础教育改革的目标是一致的，而中学生学习语言的根本目标与基础教育学会求知，学会做事，学会合作，学会做人的目标是一致的，真实新颖的选材对基础英语教学课程改革具有重要的反作用。
新闻报道类阅读理解技巧点拨：
新闻报道类类文章有一共同特点，即都是由标题（Headline）、导语（Lead）、主体（Mainbody）、背景（Background）和结尾（End）五部分构成。标题是新闻报道中心思想高度而又精辟的概括；导语位于新闻报道的首段，高度概括新闻事实；主体则对导语概括的新闻事实进行详细叙述；新闻背景是指新闻事实之外，对新闻事实或新闻事实的某个部分进行解释或补充的材料；结尾往往是新闻事件的结果或动态展望，也是中心思想的概括并常常与新闻导语相呼应。
新闻报道中的导语非常重要，它位于文章的第一段，通过它点出新闻的主题，五个W和一个H(When,Where,Who,What,Why和How)通常是构成一则完整消息不可缺少的要素。文章往往呈现出“倒金字塔”的特征，因此读懂首句或首段至关重要。
另外，从句的使用也是此类文章的一大语言特色，因为从句信息量大，适合新闻报道的要求。此外，大量的副词和插入语的使用也是此类文章的特点。为使文章更客观、更具信服力，常用The study said…, Scientists believe that…Experts said…, It's reported that…, According to the survey…等语言。同事在阅读过程中，我们要对材料所提供信息如when, where, who, how, why等进行提问，将信息迅速提炼出来。
