  • 第1题:

    The word “crisis” (in the last line but one, paragraph 3) most probably implies _________.

    [A] a dangerous moment

    [B] the last decision

    [C] the crucial point

    [D] a brave engagement


    正确答案:C
    本题考查词义理解。crisis一词出现在全文最后一句。该句指出它是一个点(point)。由其上文即倒数第二句可知,在这个点上主人公会完成一个行为或者做出一个决定,这个决定必然使他进入进一步发展轨迹(造成某些一般结果的点)。可见,crisis指的是戏剧中决定情节发展的关键性的转折点,而不是“时刻”、“决定”或“约定”。[C]正确。
