28、 thoughtless move could ruin the enjoyment.答案及剖析:1.is recognized考查时态和语态。由语境可知,此处叙述的是现在的事情,故用一般现在时,主语Go与谓语动词recognize为被动关系,故填is recognized。2.In考查介词。in other words“换句话说”为固定短语,位于句首,故填In。3.used考查非谓语动词。句意:这一隐喻最早由晋代佛教大师智道林使用,反映了围棋的本质。分析句子可知,The metaphor (比喻)与use在逻辑上是被动关系,所以用过去分词used。4.themselves考查代词。句意:当他
29、那个时代的学者们常常陷入关于生命和宇宙的哲学辩论时,他更喜欢下围棋。他相信围棋充满了生活的哲理。主语与宾语表示同一个人时,宾语用反身代词。所以填themselves。5.which/that考查定语从句。句意:当他那个时代的学者们常常陷入关于生命和宇宙的哲学辩论时,他更喜欢下围棋。他相信围棋里充满了生活的哲理。分析句子可知,Go为先行词,在后面的定语从句中作主语,所以此处填which/that。6.directly考查副词。句意:有时人可以直接面对挑战者,有时必须采取间接的方法来面对挑战者。directly为副词修饰动词face。7.how考查宾语从句。句意:一个小小的围棋棋子的恰当摆放就像一个人如何解决生活中的难题一样。to为介词,后接宾语从句,根据句意可知,空处缺少表示方式的连接副词how。8.playing考查非谓语动词。句意:下围棋的目的不仅仅是为了赢,更重要的是在这个过程中寻求智慧。分析句子可知,of为介词后接动名词playing。9.wisdom考查名词。句意:下围棋的目的不仅仅是为了赢,更重要的是在这个过程中寻求智慧。seek 为及物动词后接名词wisdom作宾语。故填wisdom。10.enemies考查名词复数。句意:他们不是以敌人的身份在博弈,而是合作下好一盘棋。enemy为可数名词,其前无任何修饰成分,所以空处应填enemy的复数enemies。
