我今天跟着小编，我们重点来分析以下几个题目。Q2. What is the advantage of observing stars from a location near the equator?更多详情请看下文 。
Q2. What is the advantage of observing stars from a location near the equator?
A. The horizon tends to be clearer there than anywhere else.
B. More stars rise and set in pairs there than anywhere else.
C. Zenith stars shine even brighter there than they do farther north or south.
D. The sky appears more orderly there than it does farther north or south.
首先，就出题顺序而言，这是第二题，问靠近赤道的方位观察星星有什么优势。从题干和出题顺序判断，对应听力内容，大致位置应该是在方法概括上，录音还并没有进行到方法介绍。
然后，我们再看选项。A项说赤道附近的地平线比其他地方更加清楚。A选项是可以直接排除的，因为录音全篇是在描述“观天定位”，而A项的关键信息却是horizon，明显与主题不符，术语第四种情形(无中生有)，所以可以大胆排除。
B、C两项的关键信息分别是’stars rise and set in pairs’和’zenith stars’，B项指代的是具体方法里面的star pair，C项是zenith star。很显然，不需要读完整个选项的句子，就可以排除这两项了，因为它们提前出现在了不该出现的顺序上。
所以，最后还算靠谱的只剩下了D项。为了保险起见，我们不妨看一下D项讲的是什么。D项说比起更北边和更南边的天，赤道附近的天是更有顺序而言的。这正好与录音中’early observers of the stars in Polynesia or really anywhere along the equator would feel that they were at the very center of things, with the skies to the north and the skies to the south behaving identically’对应。
我们再来看它的第三题。
Q3. What does the professor say about the people of the Gilbert Islands?
Choose 2 answers.
A. They developed a method for describing the locations of stars.
B. They regularly traded with the peoples of Hawaii and New Zealand.
C. They were the first to recognize the usefulness of zenith stars.
D. They considered a navigator to be the same as an astronomer.
这是一道双选题。很多考生做双选题的正确率不是很高，很多情况是直选对了其中一项，另一项选错了。当然也有“成功”避开正确两项的可能。看一下题干，锁定关键词是Gilbert Island，所以可以定位于方法介绍部分的第一小部分。
再看选项，B项的关键词是’trade, Hawaii, New Zealand’，虽然Hawaii和New Zealand在录音中出现过，但对应的并非trade, 该词在录音中并为体现，所以B项术语混搭错误的。C项是很典型提前出现，当zenith star出现，该项甚至可以不需要细读了。所以最终只剩下AD两项了。
下面我们分析第5题。它是除复听题外的最后一题。
Q5. What did the technique using zenith stars have in common with the technique using star pairs?
A. Both could help identify a location relative to the equator.
B. Both seem to have been used to determine the positioning of stone canoes.
C. Both were first developed by the Vikings.
D. Both were used as calendars to help keep track of the seasons.
通过问题，我们不难发现，这道题合并了最后两种方法(zenith star和star pair)设置了一道题目。问这两种方法的共同点是什么。其实这个题可以采用直选法——这两种方法都利用了靠近赤道这一地理优势。
选项中，B项关键信息是stone canoes，属于滞后出现，排除;C项关键词’first developed, Vikings’，虽然Vikings却是在录音中出现过(开头部位)，但这两种方法都是太平洋岛民发明的，所以C项属于混搭错误;D项的关键词是calendars，这非常明显地偏离了主题(navigation technique)。
综上所述，通过分解听力录音划分部分，进而通过每一部分所讲的内容来判断选项，在某些题目中是比较有效的。考生朋友们在平时做题时，需要留心观察，除了听懂内容外，利用定位排除的方法也能快速排出一些错误(干扰)选项，以便充分利用宝贵的做题时间。
