让步状语从句
引导方式状语从句的从属连词有: as(正如，按照)、as if/though(好像，仿佛)。
as if或as though引导的从句与事实相反时，通常用虚拟语气：
与现在事实相反时，从句用一般过去时;
与过去事实相反时，从句谓语用“had+过去分词”;
与将来事实相反时，从句谓语用“would/could/might+动词原形”。从句内容与事实相符或可能成为事实时，则用陈述句语气。

1.in order that与so that引导的目的状语
意思是“以便……；为了……”；
状语从句中谓语应用“could/should/might/would+动词原形”。in order that比so that正式，其引导的状语从句可置于主句之前或之后；而so that引导的从句只能置于主句之后。
2.for fear that与in case引导的目的状语从句
for fear that表示“唯恐，生怕”；in case表示“以免，以防”。

地点状语从句
【温馨提示】
where既可以引导定语从句，也可以引导地点状语从句。引导定语从句时，从句前应该有一个表示地点的名词作先行词，where可以变为“介词+关系代词”形式；而状语从句前则没有先行词。
