Data from the pioneer spacecraft of the National Aeronautics and Space Administration(NASA) apparently prove the theory that the searing 900-degree Fahrenheit surface temperature of Venus is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide.Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere,warmsits surface,and is converted to heat radiation that is then held in by the atmosphere.The orbiting spacecraft sampled Venus’ atmosphere from top to bottom,enabling NASA’s scientists to establish the exact amount of sunlight absorbed at various places in the planet’s atmosphere and on its surface.Measurements of atmosphere composition,temperature profiles,and radiative heating predicted Venus’ surface temperature very accurately.The planet is closer to the Sun than is Earth,and it has a relatively thin atmosphere like Earth’s .but Venus’ atmosphere consists of more than ninety percent carbon dioxide,compared to less than four percent in that of Earth.Because of its higher percentage of carbon dioxide,Venus studies are believed to be important to the understanding of possible adverse effects on Earth’s agriculture and sea levels that could result from the long-term use of fossil fuels,which add carbon dioxide to the atmosphere.
32.According to the passage,what happens to heat radiation Venus?
A.It is neutralized at the planet’s surface.B.It creates energy.
C.It is trapped by the atmosphere.D.It circulates evenly.
34.From the passage it can be inferred that the burning of fossil fuel on Earth may cause _____.A.more carbon dioxide to enter sea water B.the planet’s temperature to change
C.more sunlight to reach the Earth’s surface D.the atmosphere to become thinner
35.According to the passage,data from the Venus study can be used to ______.
A.predict changes in the planet’s orbit
B.predict future agricultural problems on Earth
C.test the efficiency of a spacecraft
D.test a theory about more efficient greenhouse

32题,根据原文
“Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere,warmsits surface,and is converted to heat radiation that is then held in by the atmosphere.” 可知答案应该选C 因为,“ trapped by the atmosphere”就是“held in by the atmosphere ”的另一种说法
34题,选B.因为,A,C,D的叙述均与原文意思不符.唯独B可由原文意思推敲,即大量燃烧化石燃料,可导致地球大气中的二氧化碳含量增加,进而导致全球温度的变化.
35题,首先排除A,因为探测的数据与预测轨道没有关系,而C虽然可能符合逻辑,但是不符合原文主旨,所以排除；而D,“more efficient greenhouse”与原文也不相符；最后B,根据原文最后一句可知是正确答案.
