定语从句与强调句区别.doc

强调句及强调句与定语从句的区分首先我们来看下面这道题：“Where did you find the professor who made the speech yesterday?” “It was in the hall _ the students often have a meeting.”A. where B. which C. that D. when很可能误选C，认为这是一个强调句，强调地点状语 in the hall。假若选C，即有 It was in the hall that the students often have a meeting，该句的意思是“学生们通常是在大厅开会”，单独看这一句，无论是其意思还是其语法均未错，但若将其与上文联系起来看，则不通，因为上文的意思是“你是在哪儿找到昨天作报告的那位教授的?”假若将答句改为 It was in the hall that I found the professor，则完全可以。其实，此题的最佳答案是A，where the students often have a meeting 为定语从句，用以修饰其前的名词 the hall，句意为“是在学生们经常开会的那个大厅(找到教授的)”，这样语意就通顺了。定语从句与强调句句式结构用法比较：由it引导的句型结构，常可构成强调句或定语从句，两者极易混淆。一般来说，如果将it is/was.与连接词去掉，句子仍然正确，就为强调句型。这时，就选用that连接词;否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。例1. (1) It is on the island that they spent 10 years.(2) It is the island where (on which) they spent 10 years.比较：(1)该句为强调句。表示地点的名词the island前有介词与其连用，说明它是一个完整的地点状语。如果将it is去掉：They spent 10 years on the island.它的意义仍然完整。故应选用连接词that构成强调句式 (注：强调地点状语时，不可用where连接)。(2)该句为定语从句。表示地点的名词the island前没有介词与其连用，说明它不是一个完整的地点状语。如果将it is去掉：They spent 10 years the island.它的意义不完整。故应选用关系副词where或on which 构成定语从句结构。例2. (1) It is on the date that she went abroad.(2) It is the date when (on which) she went abroad.比较：(1)分析句子结构可知，在表示时间的名词the date 前有介词与其连用，说明它是一个完整的时间状语。如果将it is去掉：She went abroad on the date.它的意义仍然完整。故应选用连接词that构成强调句式(强调时间状语时，不可用when连接)。(2) 分析句子结构可知，在表示时间的名词the date 前没有介词与其连用，说明它不是一个完整的时间状语。如果将it is去掉：She went abroad the date.它的意义不完整。故应选用关系副词when或on which 构成定语从句结构
