问题     Writing Based on Reading and Listening
    Directions:
    For this task, you will read a passage about an academic topic and you will listen to a lecture about the same topic. You may take notes while you read and listen.
    Then you will write a response to a question that asks you about the relationship between the lecture you heard and the reading passage. Try to answer the question as completely as possible using information from the reading passage and the lecture. The question does not ask you to express your personal opinion. You may refer to the reading passage again when you write. You may use your notes to help you answer the question.
    Typically, an effective response will be 150 to 225 words. Your response will be judged on the quality of your writing and on the completeness and accuracy of the content.
    You should allow 3 minutes to read the passage. Then listen to the lecture. Then allow 20 minutes to plan and write your response.
    Write your response in the space provided.
    Reading
    You will have 3 minutes to read the passage.
    Recently, NASA has announced that after extensive observation the astronomers on the space station have discovered yellow light radiating from Mercury. This has many people speculating about the cause of this. There are three good possible explanations for this phenomenon.
    Firstly, according to scientific studies, the radiation of ultraviolet light from the sun during the day makes the oxygen atoms on earth become oxygen molecules, and it is this process that generates yellow light. Observing Mercury through this yellow haze naturally makes people think that this light is radiating from Mercury.
    Secondly, according to some meteorologists, lightning may be responsible for the appearance of yellow light. When lightning flashes, people see a kind of harsh light radiating from it and may mistake it for yellow light from Mercury.
    There is a third position that claims the yellow light people claim to have seen radiating from
    Mercury does not exist at all. Because people living in different areas will be influenced by their own climate when doing the observation, this yellow light may be just produced as an illusion in a specific region.
    Then you will hear:
    Now listen to part of a lecture on the topic you just read about.
    Lecture
   
    Question
    Summarize the points made in the lecture you just heard, explaining how they cast doubt on points made in the reading passage.
Recently, the discovery of radiation of yellow light from Mercury has been explained in three different ways, all of which we believe are far-fetched.
    Some scientists assert that the light produced in the process by which radiation of ultraviolet rays from the sun in the daytime turn oxygen atoms into oxygen molecules is yellow; however, other scientists have observed that the light produced in this process is actually green, not yellow.
    The second possible reason for the yellow light presented by the reading is lightning.However, according to meteorologists, the natural phenomenon of lightning usually occurs during the day, not at night. But the radiation of yellow light from Mercury, on the contrary, often happens at night. This suggests that lightning cannot explain the radiation of yellow light because the two phenomena do not typically occur at the same time.
    As to the suggestions that this kind of yellow light is actually an illusion caused by climate differences in different regions, there is other proof that shows this is an unreasonable explanation. The yellow light has not been observed from only one specific area, but has instead been seen by people in different locations. What’s more, this light has been observed through professional, precise scientific instruments. Therefore, the yellow light is not an illusion, but a genuine natural phenomenon.

选项

答案     In the lecture the professor questions the reading’s assertion that there are three reasonable explanations for the observation of yellow light radiating from Mercury. The professor then explains why he does not agree with the reading.
    The reading’s first explanation for the yellow light people see is that they live in a yellow haze caused by the radiation of ultraviolet light from the sun that makes the oxygen atoms on earth become oxygen molecules. The professor does not think this is a reasonable explanation because he claims some scientists observe the light as yellow, while others observe the light as actually green.
    The reading’s second explanation is that the yellow light attributed to Mercury is actually caused by lightning. The professor disagrees, saying that the yellow light from Mercury is often observed at night while lightning most commonly occurs during the day. Since these two phenomena do not typically occur at the same time, lightning is not a reasonable explanation for the yellow light.
    The reading’s final explanation is that the yellow light is an illusion caused by a specific climate. The professor rebuts this by saying that the yellow light has been observed from more than one location and through precise, scientific instruments. Therefore, it can’t be claimed that the yellow light is an illusion caused by the climate of one specific region.

解析     针对NASA对黄色光线的观察,阅读文章认为有三点可以解释水星产生黄色光的原因。一是紫外线把氧原子变成氧分子;二是闪电;三是特殊气候条件。而听力文章则认为这三点都存在纰漏,不具有说服力。
