高考状语从句知识点
高考状语从句知识点状语从句是高考英语中的一个重要知识点，掌握好它对于我们在高考中取得好成绩可是相当关键哦！今天咱们就来好好聊聊状语从句。
先来说说啥是状语从句。
简单来讲，状语从句就是用一个句子来充当状语。
那啥是状语呢？就好比咱们跑步的时候，给你加油打气的那些话，告诉你跑快一点、跑慢一点、往这边跑、往那边跑，这些起辅助说明作用的就是状语。
而用一个句子来做这个辅助说明的工作，那就是状语从句啦。
状语从句的种类那可不少，有时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句和方式状语从句等等。
咱们先来说说时间状语从句。
比如说“When I was a child, I often played in the park” 这里的“When I was a child”就是一个时间状语从句，表示“当我还是个孩子的时候”。
再比如“While I was doing my homework, my mom was cooking dinner” 这里的“While I was doing my homework”表示“当我正在做作业的时候”。
记得我以前教过一个学生，叫小李。
有一次考试，他就因为时间状语从句丢了不少分。
那次考试有一道题是这样的：“＿_____ he came in, I was reading a book” 选项有“When、While、As”。
这小李啊，想都没想就选了“While”，结果就错啦。
后来我给他分析，这题应该选“When”，因为“While”强调的是动作的同时进行，而这里“came in”是一个短暂性动作，“reading a book”是一个持续性动作，所以要用“When”。
从那以后，小李可长记性了，每次遇到时间状语从句的题都会仔细分析。
接下来是地点状语从句。
像“Where there is a will, there is a way” 意思就是“有志者，事竟成”，这里的“Where there is a will”就是地点状语从句，表示“有意志的地方”。
