8、at I forgot my ticket till/until I got to the station.(3)till不可置于句首，until可以。(4)强调和倒装句中，not .until应视为一个整体，同时被强调或置于句首。It was not until you told me that I had any idea of it.Not until you told me did I have any idea of it.3. before和since的用法(1)before常用于表示“还未就；不到就；才；趁；还没来得及”等含义。We had sailed four days an

14、从句1. so that引导的目的状语从句及结果状语从句的区别：(1)so that引导目的状语从句时，只能置于主句之后，从句谓语部分常需用情态动词can, may, could等，可用in order that代替。后者更正式，引导的状语从句可置于主句前或后。(2)so that引导结果状语从句时，从句的谓语部分一般没有情态动词，其作用等于so。试比较：We got up early so that we could catch the train. (此句只强调早起的目的，结果未明)We got up early so that we caught the train. (此句表明了早起的
15、结果：赶上了火车)2. so .that与such .that引导结果状语从句的区别：其规律由so与such的不同词性决定。such是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。常见以下几种句型结构：(1)so形容词/副词that从句。He was so excited that he could not say a word.(2)sucha/an形容词单数可数名词that从句。Its such a good chance that we must not miss it.(3)such形容词复数名词/不可数名词that从句。It was such fine weather

18、rd, youll make progress. (真实条件句)If you had worked harder, you would have passed the exam. (虚拟条件句)2. “祈使句and .”和“祈使句or/otherwise .”以上两种结构中的祈使句都表示条件， and或or/otherwise后面的内容表示结果。Climb to the top of the mountain and youll see the whole city. If you climb to the top of the mountain, youll see the whole ci

22、 you will be.2. A is to B what/as X is to Y结构。Food is to men what oil is to machines.九、方式状语从句1. 方式状语从句表示动作的方式。as之前常可用just加强语气。When in Rome, do as the Romans do.I did just as the teacher did.2. as if/as though引导方式状语从句时，常用虚拟语气。He talks as if he knew everything in the world.She spoke English so well as
23、 if she had been to America.状语从句是高考英语的一个十分重要的考点，几乎每年都考。综观历年高考英语试题以及近年来各省市试题，我们发现高考对状语从句的考查主要涉及引导状语从句的从属连词的用法与辨析。由于高考对状语从句的考查主要涉及引导状语从句的从属连词的用法与辨析，所以在做状语从句考题时，考生在特别注意以下几点：(1) 要弄清状语从句的几个主要类别：如时间状语从句、条件状语从句、原因状语从句、地点状语从句、目的状语从句、结果状语从句、让步状语从句等，同时弄清它们相应的主要“引导词”及其相关意义。(2) 学会用语境分析法解题：综观历年高考英语状语从句考题，至少有90%的
24、考题可通过分析语境来解决。具体做法是，将四个选项分别放入题干中，意思最明确，逻辑最通顺，最合情合理的，就一定是最佳答案。(3) 留意某些含有状语从句的特殊句式：如it issince，notuntil，hardlywhen，no soonerthan等。(4) 排除命题干扰：有时命题者为了增加试题的难度和灵活性，可能会在题干中增加干扰成分，如增加修饰语或插入独立结构或插入语，使用省略结构或省略句式等，同学们在做题时要注意排除这些干扰。【真题分析】一、单项选择1.
