一、表语从句
在复合句中,位于系动词之后作表语的从句称为表语从句。引导表语从句的引导词主要有以下几类:
类别 例词 说明 从属
连词 that,whether 两者在从句中都不作成分,that无实义;whether意为"是否",不能替换 连接
代词 who,whose,what等 在从句中作主语、宾语、表语、定语等 连接
副词 when,where,why,how等 在从句中作时间、地点、原因、方式状语等 其他
连接词 because 主句主语不用reason as if/though 从句情况发生的可能性较小时,常用虚拟语气 The most important thing is that we should find enough water for the oxen.
最为重要的是我们应该为牛找到足够的水。
