问题 Do the following statements agree with the information given in Reading passage ? In boxes on your answer sheet, write
TRUE         if the statement agrees with the information
FALSE        if the statement contradicts the information
NOT GIVEN    if there is no information on this
To determine longitude, the measurement of the distance from the Moon to the given star is a must.
选项 A、TRUE
B、FALSE
C、NOT GIVEN
答案B
解析 为了精确地计算经度，必须测定月球到某一恒星的距离。题干关键词为the Moon、to the given star、to determine longitude。这些词基本在原文中都原词重现了，定位到B段：To determine longitude，navigators had no choice but to measure the angle with the naval sextant between Moon centre and a specific star—lunar distance—along with the height of both heavenly bodies．本题解题的关键在于对这句长难句的理解以及lunar distance的理解。我们可以画出这句话的主干：To determine longitude，navigators had to measure lunar distance with the naval sextant．为了精确地计算经度必须用六分仪测定月角距。什么是月角距?即破折号之前的the angle between Moon centre and a specific star(月球中心与特定恒星之间的“夹角”)，而非题干所说“距离”。因此，本题的答案为False。
