高三英语语法知识点1
虚拟语气
I 虚拟语气在if 引导的条件句中的易错点。
① if my lawyer had been here last Saturday, he would have prevented me from going.
② if you had studied hard at school, you would be a college student now.
句子①②都是虚拟语气在条件句中的使用，从句中都是假设过去的情况，所以用过去完成时，但在主句中，句①依然指代过去的情况，谓语动词是would have done，而②中含有一个表示现在的时间状语now, 这样就必须将其理解为假设现在的情况，所以谓语动词必须为would/should/might+动词原形，学生在这一点上经常会忽略now的存在，从而按句①的形式填写答案。
Ⅱ虚拟语气在名词性从句中的用法
1.在it is important (strange, natural, necessary……)+that 句子或者It is decided (ordered,suggested, demanded, advised……)+that句子中，主语从句中的谓语动词常用(should)+动词原形结构，表示某事“重要”、“必要”、“被决定”等
例如：① it is important that everyone (should ) obey the rules all day and all night.
② it is decided that the meeting (should) be held tomorrow afternoon.
2. suggest, insist 后面指宾语从句时需注意的地方
1)①suggest 当“建议”“提出”讲时，其后宾语从句的谓语动词常用“should+动词原形” 例如：He suggested that the work (should) be started at once 他建议立即动工。
类似的动词还有insist坚持，demand要求，desire要求、请求，request请求，require要求、需要，order命令，propose建议，command命令，ask要求，advise建议，prefer宁愿等。 这些动词变被动语态(如：It is suggested + that主语从句)形式后，主语从句谓语动词仍用“(should)+动词原形” 这些动词变名词(如suggestion)后，其后的表语从句和同位语从句中的谓语部分仍用“(should)+动词原形”
②suggest 当“提出(某看法)，暗示，启发”讲时，其后宾语从句的动词不用虚拟语气。 例如：(1)The police suggested that the thief might be one of the family member
警察局提出窃贼可能是一名家庭成员。
(2)Her yawns suggests that she is sleepy. 她打哈欠表明她困了。
(3)Although he didn’t suggest that we __ the decision to swim across the river, but his look suggested that our decision __wrong.虽然他没提出我们应该终止游过这条河的决定，但他的表情表明我们的决定是错误的。
A：stop; wasB: should stop; be
C: stopped ;wasD: stopped; should be
在这个句子中，前一个suggest当“建议”“提出”讲，而后一个作“表明”讲，所以答案为“A”
2)①insist作“坚决要求…该…;坚持认为…定要…”讲时，其后宾语从句的谓语动词用“(should)+动词原形”
例如：I insisted that you (should) be there on time.我坚持认为你应该准时到那里去
②insist 作“坚持(意见，看法);坚持说，确信”讲时，其后从句不用虚拟语气。
例如：He suggested (that) he heard someone in the next room. 他坚持说他听到隔壁屋子里有人。

一、that 从句
1、主语从句
(1)that从句作主语时，常用it作形式主语，常见的句型有：
It+be+形容词(obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句
It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.)+that从句
It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句
(2)that可以省略，但that从句位于句首时，that不能省略。
2、宾语从句
(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词之后，如think, make, consider等，可以用it作形式宾语。
(2)That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。
3、表语从句(that不可省略)
4、同位语从句
连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。
二、whether/if从句
1、在表语从句和同位语从句中只能用whether不能用if;当主语从句放于句首时，只能用whether不用if;当it作形式主语，主语从句放在句末时用whether或if均可;discuss后引导宾语从句时，必须用whether。
2、在宾语从句中：
(1)及物动词后：whether从句中不能有否定式，宾语从句为否定句时用if;if不能与or not连用，但可以用whether or not;whether后可以加不定式。
(2)介词后：只能用whether,不用if。

含有状语从句、名词性从句和定语从句的复合句
用or, and, so, if 填空

2.Follow your doctor’s advice, ________ your cough will get worse.(If you follow your doctors advice, your…)
3.The WTO can not live up to its name ______it does not include a country that is home to one fifth of mankind.

用but, and, so , when, since, while, as 填空
1. I do every single bit of housework _____ my husband Bob just does the dishes now and then.
2. ---I think George doesn’t really care for TV plays.
---Right, ______ he still watches the program.
3. What he said is strange, ________ yet it is true.
1. while 2. but 3. and
归纳：常用于表示转折的连词有：but, still, however, and yet, while, when等。连接两个意义相反的并列分句，表示转折。这些次的用法区别是：but连接并列分句，不用逗号搁开，注意不能将although(though)与but 同时使用;however常用于句首、句中，用逗号搁开;yet构成and yet, 等。

高三英语语法知识点5
1.The boss of the company is trying to create an easy atmosphere __where__his employees enjoy their work.
解析：本句中定语从句“his employees enjoy their work”不缺主宾表，先行词为atmosphere，表示“气氛，氛围”。将“in+先行词atmosphere”还原回从句中成立，因此答案为where。
2.As the smallest child of his family，Alex is always longing for the time __when__he should be able to be independent.
解析：分析结构可知，此处是定语从句，先行词为time。定语从句为空格后句子，缺少时间状语，用when引导。句意：作为家里最小的孩子，亚历克斯总是渴望他应该能独立的时候。
3. Some experts think reading is the fundamental skill upon __which__ school education depends.
解析：本句为定语从句。引导词在定语从句中位于介词upon的后面作宾语，故用关系代词且指代先行词the fundamental skill，因此用which。
4.It is a truly delightful place, __which__ looks the same as it must have done 100 years ago with its winding streets and pretty cottages.
解析：此句是一个非限制性定语从句，先行词是place，定语从句中缺主语，故用关系代词which。句意：这真是一个宜人的地方，这里蜿蜒的小路和美丽的小村庄一定和100年前看起来是一模一样的。
5.The books on the desk，__whose__covers are shiny，are prizes for us.
解析：此句是非限制性定语从句，先行词为the books，________和covers之间存在所有关系，意为“书的封面”。句意：桌上的书是给我们的奖励，那些书的封面闪闪发光。根据语境填whose。
6.He wrote many children's books，nearly half of __which__ were published in the 1990s.
解析：此句为非限制性定语从句，先行词是children's books，定语从句中of缺少宾语，故填which。句意：他写了许多儿童书籍，差不多一半左右是在20世纪90年代出版的。
7.Nowadays，school violence is a hot issue. I think this is a phenomenon，__which__calls for our great concern.
解析：句意：目前，学校暴力是个热点问题。我认为这是一个需要我们极大的关注的现象。从句子结构分析可以看出，空白后面句子是一个非限制性定语从句，对前面句子进行补充说明。
