条件状语从句的用法；-in后缀的用法；
时间状语从句由when, while, as sn as, befre, after等引导。时态规则：主将从现：在含有时间状语从句的复合句中，如果主句用一般将来时，从句用_____________。主过从过：表过去发生的动作，主句用一般过去时，从句也用一般过去时。例句：I will g with yu when I get the bus ticket tmrrw.He will call yu as sn as he arrives.
1．时间状语从句的用法
1) when “当……时候 ”可接延续/短暂动作，主从句动作可同时，也可先后。例如：I was reading when he came in. 他进来时我正在看书。2) while “当……期间 ”只接延续性动作/进行时，强调“在……过程中”。例如：Please be quiet while I am talking. 我讲话时请安静。
3) as “一边……一边；随着” 强调主从句动作同时发生。 He sang as he walked. 他边走边唱。4) befre “在……之前” Wash yur hands befre yu eat. 饭前要洗手。5) after “在……之后” I will call yu after I arrive hme. 我到家后给你打电话。
6) since “自从……以来”主句常用现在完成时，从句一般过去时。 I have lived here since I was a child. 我从小就住在这里。7) until / till “直到……” I waited until he came back. 我一直等到他回来。8) as sn as “一……就……” I will tell him as sn as he cmes back. 他一回来我就告诉他。
-al 是英语中非常高频的后缀，可以用来把名词变成形容词，意思是 “关于……的”、“具有……性质的”。如：natin (国家) → na-tin-al (国家的)例句：Beijing is ur natinal capital.北京是我们的首都。
nature (自然) → na-ture-al (自然的)例句：We shuld prtect the natural envirnment. (我们应该保护自然的环境。)culture (文化) → cul-ture-al (文化的)例句：He likes learning abut different cultural custms.(他喜欢了解不同的文化的习俗。)
3．条件状语从句的用法
1) 什么是条件状语从句？ 表示“如果……、假如……”，说明动作发生的条件的从句。 引导词最常用：if（如果），unless（除非，如果不）2) 核心考点：主将从现 如果主句是一般将来时，从句只能使用____________代替一般将来时。
3) if 引导的条件状语从句结构：If + 一般现在时，主语 + will + 动词原形 主语 + will + 动词原形 + if + 一般现在时例句：If it rains tmrrw, we will stay at hme. 如果明天下雨，我们就待在家里。I will g shpping if I have time. 如果我有时间，我就去购物。
4) unless 引导的条件状语从句unless = if ... nt（除非，如果不） 语气更强，也要遵循主将从现原则。例句：Yu will fail the exam unless yu study hard.= Yu will fail the exam if yu dn’t study hard.除非你努力学习，否则你考试会不及格。
5) 其他注意点主句可以是祈使句：If yu are tired, have a rest.主句可以含有情态动词：If yu dn’t knw the wrd, yu can lk it up.
-in 是英语中常见的名词后缀。它用来把动词变成名词。只要你看到单词结尾是 -in（变体还有 -atin, -tin, -sin, -ssin），基本可以确定它是个名词，表示“一种动作、状态或结果”。如：act (行动) → ac-tin (行动; 行为)例句：This is a kind actin. (这是一种善举。)
instruct (指导) → in-struc-tin (指导；教学)例句：The teacher gave us clear instructins. (老师给了我们明确的指导。)decide (决定) → de-ci-sin (决定)例句：It was a difficult decisin. (这是一个艰难的决定。)
5．副词的比较级和最高级的用法
1) 什么是副词？ 用来修饰动词、形容词、其他副词，表示时间、地点、方式、程度等的虚词。如：fast（快地）、well（好）、hard（努力地）2) 副词比较级和最高级的变化规则规则变化一般单音节副词，直接加 -er / -estfast → faster → fastest hard → harder → hardest
以 -ly 结尾的副词（大部分双音节/多音节），前面加___________quickly → mre quickly → mst quicklyslwly → mre slwly → mst slwlycarefully → mre carefully → mst carefully③ 以 y 结尾，_______________________early → earlier → earliest
变 y 为 i，再加 -er / -est
不规则变化（必考）well → better → bestbadly → wrse → wrstmuch → mre → mstlittle → less → leastfar → farther / further → farthest / furthest
3) 基本句型比较级：A + 动词 + 副词比较级 + than + B 表示“A比B更……” He runs faster than his brther. 他跑得比他弟弟快。 She dances mre beautifully than Lucy. 她跳舞比露西更美。最高级：A + 动词 + (the) 副词最高级 + 范围 He runs (the) fastest in his class. 他在班里跑得最快。 She wrks (the) hardest f all. 她所有人中最努力。
比较级表示“越来越……” 单音节：比较级 + and + 比较级 It rains harder and harder. 多音节：mre and mre + 副词原级 He speaks English mre and mre fluently.“越……，就越……”The + 比较级，the + 比较级 The harder yu wrk, the better yu will learn. 你越努力，学得就越好。
复合词就是把两个或两个以上的单词，拼在一起组成一个新单词”。合成法（最常见）：单词 + 单词 = 新词名词 + 名词 = 名词bk (书) + mark (标记) = bkmark (书签)sun (太阳) + flwer (花) = sunflwer (向日葵)形容词 + 名词 = 名词high (高的) + way (路) = highway (高速公路)green (绿色的) + huse (房子) = greenhuse (温室)
派生法（后缀法）：词根 + 后缀 = 新词加后缀（最常用）：care (关心/动词) + -ful (充满...的) = careful (小心的/形容词)teach (教/动词) + -er (表示人) = teacher (老师/名词)decide (决定/动词) + -in = decisin (决定/名词)加前缀：visin (视觉) + tele- (远程的) = televisin (电视)bk (书) + e- (电子的) = e-bk(电子书)
