类比比喻处

　　类比在文中主要有两种体现方式，一是明喻，即A像B一样二是暗喻，说A是B，由于暗喻更加隐蔽，出题人往往趋向于在暗喻内容上出题。考生还要熟记，“借喻或借代”也是出题人常考的地方，例如用“多米诺骨牌”进行借代等。

　　【试题回放1997-Text1】

　　The full import may take a while to sink in. The NT Rights of the Terminally Ill law has left physicians and citizens alike trying to deal with its moral and practical implications. Some have breathed sighs of relief, others, including churches, right-to-life groups and the Australian Medical Association, bitterly attacked the bill and the haste of its passage. But the tide is unlikely to turn back. In Australia &mdash where an aging population, life-extending technology and changing community attitudes have all played their part &mdash other states are going to consider making a similar law to deal with euthanasia. In the US and Canada, where the right-to-die movement is gathering strength, observers are waiting for the dominoes to start falling.

　　52. When the author says that observers are waiting for the dominoes to start falling, he means ________.

　　[A] observers are taking a wait-and-see attitude towards the future of euthanasia

　　[B] similar bills are likely to be passed in the US, Canada and other countries

　　[C] observers are waiting to see the result of the game of dominoes

　　[D] the effect-taking process of the passed bill may finally come to a stop
