表示地点和表示原因的状语从句知识点
1、地点状语从句（表示地点的状语从句）
地点状语从句由where、wherever和anywhere引导，位置较灵活可放在主句后也可放在主句前。where指“在某个地方”、wherever指“在任何地方”、everywhere指“每个地方”。例如：
Where there is a will, there is a way.
Put the book back where it is.
Wherever we go, our parents will miss us.
Anywhere you go, I will accompany you.

2、原因状语从句（表示原因的状语从句）
①because、since、as和for
A、because表示原因时语气最强，常用来回答why引导的疑问句。用于强调句强调原因时只能用because不可用其它三个词，because可和强调词just、only以及not连用。because从句一般位于主句后，也可放在主句前面表示强调。
B、since语气比because弱，表示一种附带的原因或是对方已知的事实，表示一种显然的理由，相当于汉语的“既然”，引导的从句常放在句首。since可用于省略句中（如since 、so“既然如此”），其他三个词不能用于省略句中。
C、as语气较弱，只是对主句的附带说明，表示不言自明的原因或是已知的事实。as引导的从句通常放在主句前。
D、for表示原因时语气最弱，for引导的从句并不是主句行为的直接原因，只起到一种补充说明的作用。只能放在主句后面，不可位于主句前，且用逗号同主句隔开。
例如
—Why do you disagree to the proposal?
—Because it is unpractical.(只能用because)
He cut class just because he didn’t like math. (只能用because)
It was because he received high education that he had more opportunities than others. (只能用because)
Because he broke the traffic rule, he was fined.（表示强调）
We must get rid of carelessness, for it often leads to errors.（位于主句后用逗号同主句隔开）
Since you have no time to spare, I will turn to others for help.
As I get lost, I don’t know how to go back.

②now（that）、in that
这两个连词意思相近意为“既然、由于”。now that位于句首，in that位于句中。例如：
Now (that) you have done good preparations, you needn’t feel worried.
All of us like him in that he is very humorous.
