语法考点之一:虚拟语气考点1.If从句中的虚拟语气1、与过去事实相反：从句sｂｈad ｄoｎe，主句sb wouｌd(sｈoｕlｄ, ｃould, miｇht)＋hａvｅｄoｎe；2、省略ｉf,从句的语序用到装，即将ｗere,hａd或shoulｄ移至主语的前面，但否定词not不前移。
3、与将来事实相反：从句ｓb dｉd (ｓhoｕｌd+ｄｏ或were+tｏdo)，主句sb would (shoｕld，cｏuld, ｍight)＋do。
4、错综条件句：主句与从句的动作发生在不同的时间段。
比如：从句对过去虚拟，而主句对现在虚拟，即从句sb hａd dｏne,主句sb wｏulｄ(sｈoｕld, could, mｉght)+do;考点２：表示建议、要求、命令等动词如insisｔ,ｏrdeｒ，cｏmmaｎｄ, sｕｇgest, aｄvise, prｏpose, a ｓk，reqｕire, ｒｅｑuesｔ，ｄemａnd引导的从句及it引导的相应的分词、名词和形容词从句,谓语用(should)+动词原形。
考点３:Iｔis ＋advｉsable,eｓｓenｔiａl, importaｎt, iｍpeｒative，iｎcｒediｂｌe等从句，谓语用（should)+动词原形。
考点4：it is(ｈｉgh/abouｔ)tiｍe that的结构中，从句使用一般过去式。
例如:考点5：much aｓ"尽管，虽然"引导让步状语从句，从句中用ｗｏuｌd havｅdone表示假设。
考点6：if oｎlｙ, wish，as iｆ/as ｔhoｕgｈ引导从句，与过去事实相反:ｈad ＋ｄone；与现在事实相反:动词过去式;与将来事实相反:could/woｕld＋ｄo考点7：ｗｏｕld rather／ｓoｏｎer从句中使用一般过去式或过去完成式分别表示对现在或过去的虚拟考点８:ｌesｔ/ foｒfear that+(shｏulｄ) ＋原形动词。

4. the more…the more…与 more and more
the more...the more…表示两个过程中同时递 增，是主从结构。more and more 只表示一个 过程的不断增长。如 …the wilder the range of our life and the more various the contacts we have, the wilder and suppler must be our command over a rang of English styles.

(2)区分主从句表示的不同时间概念： 主从句谓语动词所指时间不同，这叫做错 综时间条件句，动词形式应根据实际情况 来调整。如： Had it not been for the timely investment from the general public, our company would not be so thriving as it is. (主句与现在事实相反，从句与过去事实 相反)
3.（the）+adj/adv最高级+比较范围
比较级形式表示最高级意义时，比较对象的 范围应用： any other +单数名词 the other +复数名词 the others anyone/anything else 上述词是用来将比较级结构转变成最高级意 义的关键词语，切不可遗漏，否则会造成逻 辑混乱的错误 。
(3)识别事实和假设混合句： Your maths instructor would have been happy to give you a make-up examination had you gone and explained that your parents were ill at the time. (句子前半部分为假设情况，而“父母 病了”是事实)

独立主格结构独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。
前后两部分具有逻辑主谓关系。
独立主格结构在句中做状语，多用于书面语。
独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。
非谓语动词作状语，其逻辑主语须与主句主语保持一致。
若不一致，非谓语动词形式须另带主语，从而构成复合结构的形式作状语。
这种结构称为“独立结构”。
其中，非谓语动词主动用现在分词，被动用过去分词。
非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。
“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。
功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。
例如：表示时间The meeting being over, all of us went home. 开完会后我们都回家了。
Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝茶。
表示条件The condition being favorable, he may succeed. 若条件有利，他或许能成功。
表示原因There being no taxis, we had to walk. 没有出租车，我们只好步行。
He wrapped her up with great care, the night being dark and frosty. 夜又黑又冷，所以他把她裹得严严实实的。
表示伴随情况Almost all metals are good conductors, silver being the best of all. 几乎所有的金属都是良导体，而银则是最好的导体。

独立主格结构独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。
前后两部分具有逻辑主谓关系。
独立主格结构在句中做状语，多用于书面语。
独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。
非谓语动词作状语，其逻辑主语须与主句主语保持一致。
若不一致，非谓语动词形式须另带主语，从而构成复合结构的形式作状语。
这种结构称为“独立结构”。
其中，非谓语动词主动用现在分词，被动用过去分词。
非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。
“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。
功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。
例如：表示时间The meeting being over, all of us went home. 开完会后我们都回家了。
Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝茶。
表示条件The condition being favorable, he may succeed. 若条件有利，他或许能成功。
表示原因There being no taxis, we had to walk. 没有出租车，我们只好步行。
He wrapped her up with great care, the night being dark and frosty. 夜又黑又冷，所以他把她裹得严严实实的。
表示伴随情况Almost all metals are good conductors, silver being the best of all. 几乎所有的金属都是良导体，而银则是最好的导体。
(=Almost all metals are good conductors, and silver is the best of all.)用法独立主格结构主要表示谓语动词发生的时间、原因、条件或伴随情况等，相当于一个状语从句或并列句。
用作时间状语The work done (=After the work had been done), we went home. 工作完成后，我们就回家了。
用作条件状语Weather permitting (=If weather permits), they will go on an outing to the beach tomorrow. 如果天气允许的话，他们将在明天组织一次海滨小游。
用作原因状语An important lecture to be given tomorrow (=As an important lecture will be given tomorrow), the professor has to stay up late into the night. 因为明天要发表一个重要的演讲，教授不得不熬夜到很晚。
用作伴随状语He was lying on the grass, his hands crossed under his head(=and his hands were crossed under his head).他躺在草地上，两手交叉枕在脑后。
表示补充说明We redoubled our efforts, each man working like two. 我们加倍努力，一个人干两个人的活。
*注：独立主格结构表示时间、条件或原因时，相当于一个状语从句，一般放在句首，表示原因时还可放在句末；表伴随状况或补充说明时，相当于一个并列句，通常放于句末。
