(11)陈述部分是由neither...... nor....., either...... or...... 连接的并列主语时,疑问部分根据其实际意义而定 Neither your nor I am an engineer, are we?

(14)带情态动词dare或need的反义疑问句,若陈述部分是否定的,疑问部分常用“need/dare+主语” We need not to do it again, need we? He dare not say so, dare he? 当dare/need为实义动词时,疑问部分用“助动词do/does+主语” She doesn't dare to go home alone, does she? (15)❤️省去主语的祈使句的反义疑问句,疑问部分用will you/won't you/would you Don't do that again, will you?

Let us wait for him in the reading room, will you? (16)陈述部分是There be结构时,疑问部分用there,省略主语代词 There is something wrong with your watch, isn't there? There will not be any trouble, will there? (17)带否定前缀的词在功能上不视为否定词 It is impossible!, isn't it? He is not unkind to his classmates, is he? (18)陈述部分含有情态动词must时,要分两种情况:一种是must表示“必须”或“有必要”,疑问部分常用needn't ;另一种是must表示推测,意为“一定”,根据其推测的情况来确定反义疑问句 You must leave at once, needn't you? It must be going to rain tomorrow, won't it?

1.主语+谓语(不及物动词)+(状语) We are working. Birds sing beautifully. He has gone to London for holiday. We stooped to have a rest.

There是引导词本身无词义,be是谓语动词, 有时态变化, 且谓语动词的数要跟be后面的名词即主语的数保持一致,根据就近原则变换be的单复数形式。be动词还可以换成其他动词,如used to be,seem to be, appear to be, lie,live, stand, exist,remain,come,appear,enter,follow,occur等。

复合句分为并列复合句和从属(或主从)复合句。并列复合句是指并列句子中的两个分句中又内含从句;从属复合句由一个主句和一个或一个以上的从句构成。主句是句子的主体,通常可以独立存在,从句充当某种句子成分不能独立存在,根据从句充当的成分,从属复合句可分为定语从句,状语从句,名词性从句。
定语从句
定语从句在句中做定语,修饰一个名词或代词,被修饰的名词或代词即先行词,定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。 关系代词有who,whom,whose,that,which等 关系副词有when,where,why等
关系代词引导的定语从句 who, whom, whose, that, which
关系代词所代替的先行词是表示人或物的名词或代词,并在句中充当主语,宾语,定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。
1.who, whom, that这些词代替的先行词是表示人的名词或代词,在从句中所起的作用如下 Is he the man who/that wants to see you? (who/that在从句中作主语) He is the man whom/that I saw yesterday. (whom/that 在从句中作宾语)
2.whose用来指人或物,只用作定语;若指物,他还可以和of which互换 They rushed over to help the man whose car had broken down.
3. which, that所替代的先行词是表示事物的名词或代词,在句中可作主语,宾语等 A prosperity which/that had never been seen before appears in the countryside. (which/that 在句中作主语) The package(which/that) you are carrying is about to come unwrapped. (which/that在句中作宾语)
关系副词引导的定语从句 when, where, why
关系副词可替代的先行词是表示时间,地点或理由的名词,在从句中作状语 关系副词when,where,why的含义相当于“介词+which”结构,因此常和“介词+which”结构交替使用。 There are occasions when (on which) one must yield. 注意:介词后面的关系词不能省略,that前不能有介词
判断关系代词和关系副词
方法一,用关系代词还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要用关系代词,而不及物动词就要用关系副词。 This is the mountain village where I stayed last year. 方法二,准确判断关系词在定语从句中充当的成分(主宾定状),也能选择出关系代词或关系副词关系。关系词在从句中作主语,定语,宾语时,选择关系代词(who,whom,that which,whose);关系词在从句中作状语时,选择关系副词(where地点状语,when时间状语, why原因状语)
限制性和非限制性定语从句
限制性定语从句对先行词而言是不可缺少的部分,去掉它主句意思往往不明确。 ❤️非限制性定语从句是对先行词的附加说明,去掉了也不会影响主句的意思,他与主句之间通常用逗号隔开。 如This is the house which we bought last month. The house,which we bought last month,is very nice. 注意关系代词that和关系副词why不能引导非限制性定语从句?
as, which引导的非限制性定语从句
在as, which引导的非限制性定语从句中,as和which可指代整个主句,as一般放在句首位置,which在句中相当于and this或and that. As we know, smoking is harmful to one's health. The sun heats the earth, which is very important to us.
关系代词that的用法
只能用that的情况
1.当先行词本身是all,few,little, much,none, everything,anything,nothing等不定代词时,关系代词通常用that,不用which。
2.当先行词被all,every,no,little,few,one,the only,the very,the right(恰当的), the last, the same等修饰时, 关系代词通常用that, 不用which
3.当先行词被序数词(包括last next等)或形容词最高级修饰时, 关系代词通常用that, 不用which
4.当先行词既有人又有物时,通常用that不用which。
5.当先行词在主句中作表语,关系代词在定语从句中作表语时,通常用that,不用which。
6.当主句中有who或which时会避免重复,常用that
不能用that的情况
1.介词前置时
2.引导非限制性定语从句时
先行词本身是that时
状语从句9种
状语从句在复合句中作状语,根据句子的含义,它可以表示时间,地点,原因,目的,结果,条件,方式,比较,让步等。 时间状语从句when, as, while, before, after, since, once, till/until, as soon as, hardly( Scarcely)...when..., no sooner...than..., the moment, immediately, directly, instantly, every time, each time, next time, by the time 地点状语从句where, wherever 原因状语从句because, as, since, in that, seeing(that), now that, considering(that) 目的状语从句so that, in order that, in case, for fear that 结果状语从句so...that..., so that, such...that... 条件状语从句,if, unless, as long as, in case, supposing, on condition that, providing, provided(that), suppose(that) 方式状语从句as, just as, as if/though 比较状语从句as...as, not so(as)... as, than, the more...the more 让步状语从句as, although, though, even if/though, whether...or not, while, however, whatever, no matter

1.when引导的从句的谓语动词既可以是延续性动词,又可以是瞬间动词,可用于主句和从句动作同时发生或从句动作先于主句动作发生的情况。 When the film ended, people went back. 注意:when有时可用作并列连词,引导并列句,意为“正在这(那)时”,相当于and at that time。常用于be doing sth./be about to do sth./be on the point of doing sth. when...(刚要... 时突然...)等句式 We were about to leave when he came in.
2.while引导的从句的谓语动词必须是延续性的,强调主句和从句的动作同时发生 Please don't talk so loud while others are working. 注意:while有时可用作并列连词,意为“而,却”,表示对比 I like playing football while you like playing basketball.
