修饰动词、形容词、副词或整个句子，说明动作或状态特征的句子成分，叫做状语。
引导词 + 句子(在句中作状语) 状语从句
引导条件状语从句的连接词主要有：if(如果)、unless(除非) 和as lng as(只要)等。unless在意思上等于。
If it rains tmrrw, I will stay at hme.
‼️【注意】当主句表示常规性、真理性的结果时，主句用一般现在时，从句也用一般现在时，即主现从现。
If yu cl the water, it turns int ice. 如果把水冷却就会变成冰。Water turns int steam if yu bil it. 如果把水煮沸就会变成水蒸汽。
1. Yu wn’t fully experience the culture f a freign cuntry _______ yu g there in persn.  (2022·安徽)A. becauseB. unlessC. as sn as　　　　D. as lng as
2. ______ yu can use yur dictinary, yu will learn English better. A.If　　　　B.Unless　　　　C.Thugh　　　　D.Befre
时间状语从句通常由when, while, as, after, befre, since, until 等词引导，时间状语从句亦可适用主将从现原则。
【例句】①He fell asleep while/when he was watching TV. ②Mary is dancing while Sphia is singing. ③Yu were talking ludly when I came in.
①当表示“每当...….时”，一般要用when。表对比“然而”时，用while。②as引导时间状语从句时表示“当时，一边...一边”，如：We always sing as we walk. 我们总是边走边唱。
2. They have been friends 　　　they first met.  (2022·重庆)A. since　　　　B. while　　　　C. befre　　　　D. after
1. ____I tk my hand ut f the water, I nticed that the water was a lt dirtier than I thught. (2022·广州)A. If　　　　B. Unless　　　　C. When　　　　D. Thugh
让步状语从句表“虽然”，“尽管”，“即使”等概念，常由thugh/althugh(虽然，尽管)，even if/even thugh (即使)来引导。
Althugh (Thugh) he was ver sixty, (yet) he began t learn French.
thugh/althugh不能与but连用, 但可与yet或still连用。
2. _____ there were n pians in Yan’an at that time, Xian still wrte sme f his mst imprtant music there…（2018·广州）A. If B. Althugh C. When D. Because
1. __________Xu was widely cnsidered t be the best, he never stpped trying t becme better.（2021深圳）
引导原因状语从句的主要连词有because, as, since等。
because, as, since均表示“因为”，“由于”，because 语气最强，用来回答why提问，可表示已知或未知的事实。because, as, since 与s不能用在同一句子中。because+句子, because f+词/词组/ding sth.
He was late fr schl because he gt up late.
As all the seats were full, he std up.
as语气较弱，较口语化，所表的原因比较明显，或是已知的事实，所以不需要强调。as引导的从句多置于主句之前。
Since yu are ging, I will g t.
since语气比较弱，常用来表示对方已知的事实。它和as一样，前面不可用强调词和否定词nt；since往往相当于汉语中的“既然”。
1. … the crn was dying ____ there had been n rain fr a lng time. （2021·广州）A. because B. where C. whenD. if
2. Mre and mre children are interested in blind bxes ___ they wnder what is inside. （2021·山东）A. sB. becauseC. unless D. thugh
引导目的状语从句的主要连词有s that, in rder that等。
I raised my vice s that everyne culd hear me.
目的状语从句习惯用于主句之后，常用情态动词may (might)，有时也用shall (shuld)和will (wuld)。
比较：He walked very fast s that he culd catch up with us. He walked s fast that he caught up with us.
s that 以便…… ,为了…… (目的状语从句) s … that … 如此……以至于…… (结果状语从句)
结果状语从句表结果，其关联词主要有s … that, such … that等。
She is s lvely that everyne likes her.She is such a lvely girl that everyne likes her.
(1) s + 形容词（副词）+ that 从句” (2) s + many/much/few/ little(数量形容词）+ n. (复数/不可数)＋that从句(3) such + 其他形容词+n.(复数/不可数)＋that 从句(4) such + a +adj. +n. +that从句(5) s + adj. + a + n. + that从句
