A 

When scientists began observing Mars with their first primitive telescopes, they assumed from the start that the planet was peopled. The 18th-century astronomer William Herschel, noting the seasons and atmosphere of Mars, declared that ‘its inhabitants enjoy a situation similar to our own’. A century later, astronomers asserted that they could detect canals running across the Martian landscape. These canals, argued US scientist Percival Lowell, had been built by technologically advanced Martians to transport water from the poles to the equator of their drying world. ‘Martian folk are possessed of inventions of which we have not dreamed,’ he argued.

题目与答案

  1. evidence that a rock found on Earth originated on Mars.
    • A
    • B
    • C
    • D
    • E
    • F

    答案：D

    原文定位：The first is known as ALH84001, a meteorite that was blasted into space when a large body struck Mars 15 million years ago and which spiralled across the solar system to crash into the Antarctic. Analysis carried out by NASA scientist Imre Friedmann showed that the meteorite contained elements identical to those found on Mars by the Viking probes

    同义替换：「evidence」↔「showed」，「rock」↔「meteorite」，「originated on」↔「elements identical to those found on」

  2. a plan to analyse material on Mars
    • A
    • B
    • C
    • D
    • E
    • F

    答案：G

    原文定位：Current projects are hoping to clarify the question of the presence of water once and for all. These are aimed at conducting experiments to detect the presence of a substance called carbon-13 in soil and rock samples on Mars

    同义替换：「plan」↔「projects」，「analyse material」↔「conducting experiments to detect」

  3. the reason Mars is no longer similar to Earth
    • A
    • B
    • C
    • D
    • E
    • F

    答案：E

    原文定位：Mars lost its magnetic field several billion years ago,’ explains British astronomer Paul Murdin. ‘Earth retained one, and it protects our atmosphere. Without that protection, Mars’s gases and water boiled off.’ That is why they are so different today

    同义替换：「reason」↔「why」，「no longer similar to」↔「so different today」

  4. an observation suggesting that there is currently water on Mars
    • A
    • B
    • C
    • D
    • E
    • F

    答案：F

    原文定位：Some researchers believe that water from underground reservoirs still gushes through Martian valleys as occasional flash floods bubble to the surface;discovered that much of the ground in the southern hemisphere of Mars is mixed with large quantities of ice and where there is ice there is likely to be liquid water, probably underneath

    同义替换：「observation」↔「discovered」，「suggesting」↔「believe」，「currently water」↔「still gushes」

  5. a claim that construction had taken place on Mars
    • A
    • B
    • C
    • D
    • E
    • F

    答案：A

    原文定位：These canals, argued US scientist Percival Lowell, had been built by technologically advanced Martians to transport water from the poles to the equator of their drying world

    同义替换：「claim」↔「argued」，「construction had taken place」↔「had been built」

  6. a possibility that humans and Martians could share the same origins
    • A
    • B
    • C
    • D
    • E
    • F

    答案：H

    原文定位：If DNA is located, it would mean that life on Mars and on Earth may spring from the same source

    同义替换：「possibility」↔「may」，「humans」↔「life」，「share the same origins」↔「spring from the same source」

  7. 33 The 18th-century astronomer William Herschel believed that
    • the Martians were physically similar to humans
    • the Martian environment resembled that of Earth
    • members of the Martian race were extremely primitive
    • the climatic conditions on Mars were very dry

    答案：the Martian environment resembled that of Earth

    原文定位：The 18th-century astronomer William Herschel, noting the seasons and atmosphere of Mars, declared that ‘its inhabitants enjoy a situation similar to our own

    同义替换：「believed」↔「declared」，「resembled」↔「similar」，「environment」↔「situation」

  8. 本题暂无

    答案：暂无

  9. 35 What does the writer say happened in the 1960s?
    • The appearance of some regions of Mars changed.
    • Evidence of organisms was found on Mars.
    • The Martian atmosphere was tested scientifically.
    • Earlier beliefs about Mars were disproven.

    答案：Earlier beliefs about Mars were disproven.

    原文定位：Then, in the late 1960s, rocket science changed our image of Mars forever. The US Mariner probes swept past Mars and sent back pictures, not of a world covered in vegetation, as many scientists still expected, but of vistas of cratered, arid deserts

    同义替换：「earlier beliefs」↔「many scientists still expected」，「disproven」↔「hanged our image of Mars forever」

  10. 36 The study of extremophiles suggests that
    • organisms can survive on Mars
    • organisms on Earth are like those found on Mars
    • Martian conditions resemble those in Earth’s volcanoes
    • Martian crystals can survive acid conditions

    答案：organisms can survive on Mars

    原文定位：A second area of support for the idea that living organisms could survive Mars’s harshness has been provided by the study of extremophiles

    同义替换：「suggests」↔「support for the idea」

  11. 本题暂无

    答案：暂无

  12. 38 Information gained from Viking probes remains unchallenged.
    • TRUE
    • FALSE
    • NOT GIVEN

    答案：FALSE

    原文定位：Others, however, argue that the crystals could have been laid down by simple chemical processes

    同义替换：「challenges」↔「argue」

  13. 39 There is evidence that there has been significant climate change on Mars.
    • TRUE
    • FALSE
    • NOT GIVEN

    答案：TRUE

    原文定位：In the past few years, astronomers have become convinced that the Martian surface, although hostile and arid today, was once lush and welcoming. Images sent back by recent probes such as the Mars Global Surveyor have revealed dried-up riverbeds and old estuaries. Rivers poured into ancient seas, it appears, and rain swept the sodden terrain. Then catastrophe struck. ‘Mars lost its magnetic field several billion years ago,’ explains British astronomer Paul Murdin. ‘Earth retained one, and it protects our atmosphere. Without that protection, Mars’s gases and water boiled off

    同义替换：「evidence」↔「revealed」

  14. 40 Spanish scientists plan to launch space probes if DNA is found on Mars.
    • TRUE
    • FALSE
    • NOT GIVEN

    答案：NOT GIVEN

    原文定位：Professor Juan Pérez Mercader of Madrid’s Centre for Astrobiology in Spain believes that it would. ‘For a start, we will be able to find out if Martian organisms have DNA;If DNA is located, it would mean that life on Mars and on Earth may spring from the same source

    同义替换：「Spanish scientists」↔「Professor Juan Pérez Mercader of Madrid’s Centre for Astrobiology in Spain」
