一要注意两者的含义区别 二要注意状语从句和定语从句的区别 三要注意在状语从句中不可使用介词 which引导 出题者既考状语从句又考定语从句和状语从句的区别 还加入名词性从句这一干扰项 地点状语从句 1 Ifyouaretraveling thecustomsarereallyforeigntoyourown pleasedoastheRomansdo 2006天津 A inwhichB whatC

这也是与结果状语从句的一个区别 引导结果状语从句的连词有 sothat so that such that 结果状语放在主句之后 注意 在so that such that结构中一般成分齐全 这也是与as引导定语从句的区别 在so as such as这一结构中 as引导定语从句 在句中做成分 1 Rosesneedspecialcare theycanlivethroughwinter A

that Providing provided that onconditionthatgiven that 条件状语从句一般考查三点 1 在条件状语从句中常用一般现在时表示一般将来时 用一般过去时表过去将来时 2 if unless incase是考查重点 3 when还可表条件 这一点不可忽视 意思是 既然 考虑到 如
