定于从句,1)The sun is bigger than the moon,_____ we all know.A.a

横线前面有逗号，是非限制性定语从句的标志，不用 as。

LiuLan,I was ZhangAn,FanGang something just to nanchang,he plans to stay for a week.I want to take a chance on my please several classmates together Saturday at 2 o 'clock this afternoon,time,welcome your arrival.

就这个位置主语谓语宾语定语状语补语 不同的形式是不一样的主语一般是放在句首,要用主格谓语,一般为动词,要注意时态宾语,放在动词后,有宾格表语,be 或联系动词的后面 修饰名词定语,形容词状语补语,补充说明英语五种...

意思是“我对此很感激”。我不明白什么是还原结构和氧化结构。

D

C
the way +that/in which/或不要连接词

选A
here是副词,前面不能加介词to的,be due for是“发生”的意思,显然也不对,因此只能选A

修改如下：
1.“慈定于”应该是“兹定于”,兹：现在
2.没有告知会议的具体时间,如会议几点开始
3.没有告知开会的具体地点,如会议在哪个会议室或教室召开
4.“我们初三学生”转换了对象,使得发文人变成了初三学生,应改为“我校初三学生”
5.“到会参加”的“到”与“参加”意思一样,两个一起用啰嗦重复,只写到会即可
6.“敬礼”后面没有标点符号,一般应用“!”

先行词单单指物,没有修饰词,主句没有which,countries作visited宾语
visit可以是及物动词 所以没必要加 in 直接which 就可以
综上所述,可以that也可以which

限制性与非限制性定语从句区别
一、在句中作用不同
限制性定语从句对被修饰的先行词有限定制约作用,使该词的含义更具体,更明确。限制性定语从句不能被省略,否则句意就不完整。
非限制性定语从句与先行词关系不十分密切,只是对其作一些附加说明,不起限定制约作用。如果将非限制性定语从句省去,主句的意义仍然完整。
二、外在表现形式不同
...

这是分隔性定语从句.“你记得定语从句修饰关系上是不是有就近原则啊”.这句话是错的.应该根据整个句意,可以把先行词和引导词分隔开来.所以1、2两句就都能迎刃而解了

现在我们应该做的唯一的事情是找到回家的路 The only thing that we should do now is to find the way home.

1）时间不明确；（2）“务必”用语不礼貌；（3）日期前应有通知发布的单位

The news( that ) he told me is really exciting,
I'm looking for a babysitter who will look after my little sister.
Do you like the music that is sad
My father just talked to the person(that / whom ) I don't know

1.The policeman is looking for him who has come back.
2.The boy is our monitor which you talked to yesterday afternoon.
3.The beautiful woman is his mother that we met at the theatre yesterday.

第一句which指前一分句的novel,意思是我小说写完了,小说下个月就要出版了.which可以指代前面的东西啊.
第二题考对于none,neither,both,all的理解
none是一个都没有,适用于3样东西及以上
neither是两者都不
both是两者都
all是都,指3样及以上
前文说买了2支笔,所以只可能是neither或者both,而后面write一般现在时复数形式,所以选both,neither后面跟单数形式.

Looking away from people or yawning will是主语,in most cases是插入语,make是谓语动词.
if I turn toward and look at someone or something,是条件状语从句,people from almost every culture will think that I am interested.是主句,其中又含了一个that引导的宾语从句.
宾补是对宾语的补充说明,让句子意思更加完整,定语从句知识点比较多,建议去把定语从句的语法知识好好看看,然后多做练习,定语修饰名词,定语从句其实也就是一个句子修饰名词

定语从句,就是用来修饰名词或代词的句子,起到定语的作用,所以叫做定语从句.
定语从句是英语句法的重要内容之一,所以该语法项目是整个高中阶段,同时也是高考的重要考点之一.本文给大家介绍一下定语从句单项填空题的解题方法.
一、 依据先行词所表达的内容和引导词在定语从句中所担当的句子成分来确定选项.
例1.I always remember the days ________ I was taken good care of in the hospital.
A.until B.that C.when D.where
分析:句子意思是:我永远都记着我在医院里受到很好照料的那些日子.先行词the days是表示时间的.限制性定语从句可以用来修饰一个表示时间的先行词,如果关联词在定语从句中作时间状语,通常用关系副词when引导定语从句.
例2.After living in Paris for 50 years he returned to the small town________ he grew up as a child.
A.which B.where C.that D.when
分析:句子意思是:在巴黎住了50 年之后他又回到了他小时候长大的小镇.因为先行词the small town表示地点,关联词在定语从句中作地点状语,所以应当选B.
二、 注意句子中逗号的语法作用.
例1.________ is known to everybody,the moon travels round the earth once every month.
A.It B.As C.That D.What
分析:句子意思是:众所周知,月球每个月绕地球转一圈.句子中逗号说明这里是一个非限制性定语从句.能够引导非限制性定语从句、代表整个主句内容且能够放在句首的关联词只有as,所以应当选B.
例2.She washed clothes this morning,________ hadn't been washed for a week.
A.these B.those C.that D.which
分析:句子中逗号说明这里是一个非限制性定语从句.四个选项中能够引导非限制性定语从句的只有D.
三、 认定该题所考查的内容,观察所给的选项,依据语法规则选出最佳答案.
例:The doctor ________ is leaving for Africa next month.
A.the nurse is talking to him
B.whom the nurse is talking
C.the nurse is talking to
D.who the nurse is talking
分析:句子意思是:正和护士谈话的那位医生下个月要去非洲.观察所给的四个选项,可以看出它们都是完整的句子.根据本题所考查的内容,最佳答案应当是修饰先行词The doctor的限制性定语从句.依据定语从句的语法规则,首先排除A,因为him是多余的; whom the nurse is talking和 who the nurse is talking两个选项中都缺少"to",所以也被排除掉.只有C (whom / who被省略了) the nurse is talking to是唯一正确的答案.
四、 依据先行词来选择"介词+关系代词"的结构.
例1.Is this the factory ________ your father once worked?
A.at where B.which
C.in which D.that
分析:句子意思是:这就是你父亲工作过的工厂吗?先行词the factory在限制性定语从句中作地点状语,所以应当选C,in which相当于where.
例2.Whenever I meet with difficulty in my English study,Mr.Lee is the person ________ I turn for help.
A.that B.who
C.from whom D.to whom
分析:在限制性定语从句中,谓语动词"turn to"是固定的短语动词.这个句子也可以写成:Whenever I meet with difficulty in my English Study,Mr Lee is the person(who / whom) I turn to for help.所以应当选D.
五、注意先行词的特殊性和关系代词的选择.
例1.All ________ I need is an English-Chinese dictionary.
A.as B.that C.what D.which
分析:句子意思是:我所需要的就是一本《英汉词典》.先行词为all或先行词被all等词修饰时,限制性定语从句通常用关系代词that引导,所以本题应当选B.又如:
There is not much that can be done now.现在没有太多的事情可做.
I've read all the books that were borrowed from the library.我把从图书馆借的书都看完了.
That white flower is the only one that I really like.那朵白花是我唯一真正喜欢的花.
例2.This is the first composition ________ I've written in English.
A.that B.which C.what D.as
分析:句子意思是:这是我用英文写的第一篇作文.先行词被序数词或形容词最高级修饰时,限制性定语从句通常用关系代词that引导,所以本题应当选A.又如:
This is the best novel (that) I've ever read.这是我读过的最好小说.

anyone 是表示人,后面定语从句应该用who,
something,somewhered等表示物和地点的应该用that或者which.
当在强调句中时,在anyone后面用that表示特指某人,这个句子中不是特指,而是泛指,所以用who在这个定语从句中修饰anyone.

没有定语从句Nina （主语）took （谓语）20 minutes （宾语）to go to school （行为动作）
定语从句是修饰主语或宾语的 而这个句子比较干净利落 啥都没有

日前是几天前的意思,和正在矛盾了,这属于病句中的不合逻辑

兹,《现代汉语词典》中有三个解释：一是这个的意思,如兹事体大；二是现在的意思,如兹订于××年×月×日上午×时举行开学典礼；三是年的意思,如今兹,另一个读音ci跟你现在提问的无关,就不解释了.
兹因,是旧时沿用至今的公文中的一种开头语,常用于介绍信、简单的通知、邀请函（信）、请柬文体的开头,如：兹因×××事,决定干×××××,其解释最简单不过－－就是现在因为（××××）.不过现在在公文中一般已经开始避免用这个“兹”字开头了,如过去的会议通知中,一般为：兹定于×年月日在× 处开×会……,现更直接：定于×年月日在×处开×会…….

南北浪人nblr 解释的很清楚了,只有当别人不清楚你说什么的时候,你才需要用限制定语从句.
比如你只有一个妈妈,你要介绍他,非限制性从句,只是加强介绍.
而限定性从句,则是加深辨别,让对方知道你是在描述的哪一个妈妈.
就像定冠词the 一样,fish can fly 非限制性
如果你说 the fish can fly 限制性,则强调的是那条鱼.
Walk on the left side of the street until you reach the third house that is red.
Walk on the left side of the street until you reach the third house,which is red.
体会下上面两句话的意思有什么不同,注意序数词the third 和 形容词 red

这个应该是限制性的,which后的部分修饰papers.

还是作表语吧.比如
He is a well-known person.

The meeting has been rescheduled to July 31, 2006. Please be noted and confirm back.

由as,which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that.As一般放在句首,which在句中.
As we know,smoking is harmful to one's health.
The sun heats the earth,which is very important to us.
典型例题
1）Alice received an invitation from her boss,___came as a surprise.
A.it B.that C.which D.he
答案C.此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后句成为句子,两个独立的句子不能单以逗号连接.况且选he句意不通.
2）The weather turned out to be very good,___ was more than we could expect.
A.what B.which C.that D.it
答案B.which可代替句子,用于非限定性定语从句,而what不可.That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通.
3）It rained hard yesterday,____ prevented me from going to the park..
A.that B.which C.as D.it
答案B.
as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语.但不同之处主要有两点：
(1） as 引导的定语从句可置于句首,而which不可.
(2） as 代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词；若为行为动词,则从句中的关系代词只能用which..
在本题中,prevent由于是行为动词,所以正确选项应为B.
As 的用法
例1.the same… as；such…as 中的as 是一种固定结构,和……一样…….
I have got into the same trouble as he (has).
例2.as可引导非限制性从句,常带有'正如'.
As we know,smoking is harmful to one's health.
As is know,smoking is harmful to one's health.
As是关系代词.例1中的as作know的宾语；例2中,它充当从句的主语,谓语动词know要用被动式.

在先行词,即要用从句修饰的那个词后面,如果有逗号,那么这个就是非限定性定语从句!

which引导的定语从句
1、当先行词是表示事物的时候,连接词只能用which,也可以用that来代替.如：
I like the computer which cost me two thousand dollars.
He has some pictures which I often read after school.
2、当which在从句中作主语的时候,与that相同,谓语动词的单复数由先行词来决定它的单复数形式.如：
There is a book on the desk which belongs to me.
Do you know the news which makes me excited.
3、如果连接词前面有介词的时候,而且先行词是个表示事物的词时,连接词只能用which.如：
These are the buildings in which we will hold some sports meeting.
That is the room of which we run out when it fires.
4、连接一个非限制性定语从句的时候,连接词只能用which.如：
We often go to the park,which lies in the middle of the city.
They like talking about the film,which will be on in two days.

关系代词who,whom,whose,which和as能引导非限制性定语从句,而that不能；非限制性定语从句中即使缺宾语,引导词也不能省略；关系副词when,where能引导非限制性定语从句,而why不能.参考资料：http://wenku.baidu.com/view/defce4eb551810a6f52486f1.html

因为museum是可数名词单数,可数名词单数不能在句子中单独出现,前面一定要加冠词.
第一题,museum前面有冠词,所以变为肯定句应为this is the museum.
主语、系动词、表语全了,所以直接填关系词.又因为visit是及物动词,后面直接加宾语,所以填A
第二题,museum前面没有冠词,所以变回肯定句应该是this museum is.
只有主语和系动词,缺表语,所以不能直接填关系词,选D,这样这句话相当于把关系词省略了.

可以填which,that或者省略不填.
所填的词就是先行词the city,作为visit的宾语.
整句话的意思就是“这就是我去年所访问的城市.”

定语从句有限制性和非限制性两种.限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如：
This is the house which we bought last month.这是我们上个月买的那幢房子.（限制性）
The house,which we bought last month,is very nice.这幢房子很漂亮,是我们上个月买的.（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith,who was my former teacher,retired last year.查理·史密斯去年退休了,他曾经是我的老师.
My house,which I bought last year,has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园.
This novel,which I have read three times,is very touching.这本小说很动人,我已经读了三遍.
3) 非限制性定语从句还能将整个主句作为先行词,对其进行修饰,这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant,which greatly upsets me.他似乎没抓住我的意思,这使我心烦.
Liquid water changes to vapor,which is called evaporation.液态水变为蒸汽,这就叫做蒸发.
说明：关系代词that和关系副词why不能引导非限制性定语从句.
看下这个：

不对,一个句子只能有一个谓语,你这里is和refused 不可同时当谓语,refused 一定要在从句中this is why he refused us for the reason.用why 当宾语从句关系词.for在这表原因.这从句可看为两个简单句的结合:this is the reason和he refused us for sth

lz的思维无法理解.我浅薄了

解题思路：由于地球自西向东自转，同纬度地区的不同地点见到日出的时刻就会有早晚．相对位置偏东的地点，要比相对位置偏西的地点先看到日出，时刻较早．这种因经度不同而出现的不同时刻，称为地方时．经度每隔15°，地方时相差1小时．同一条经线上的各地，地方时相同．区时就是所在时区中央经线的地方时．

第l9届世界杯足球赛在南非约翰内斯堡当地时间（东二区）20：00进行，可以得到30°E的地方时为20：00，上海的经度在120°E，根据“东早西晚、东加西减”可以得到上海的时间为2：00，符合的现象是繁星闪烁．
故选：D．

考点点评： 主要考查了地方时和区时的计算，要求学生熟练掌握相关知识并能灵活运用于分析解答．

非限定性定语从句起补充说明作用,缺少也不会影响全句的理解,在非限定性定语从句的前面往往有逗号隔开,如若将非限定性定语从句放在句子中间,起前后都需要用逗号隔开.
1.限定性定语从句:从句不能省略,如果省略整个句子意思不完整.
　　非限定性定语从句:从句可以省略,如果省略整个句子意思仍然完整 .
　　2.限定性定语从句:先行词可以用that 引导.
　　非限定性定语从句:先行词不可以用that 引导.
　　3.限定性定语从句:引导词有时可以省略.
　　非限定性定语从句:引导词不可以省略.
　　4.限定性定语从句:主句与从句不需要用逗号隔开.
　　非限定性定语从句:主句与从句需要用逗号隔开.
　　5.限定性定语从句:从句只修饰先行词.
　　非限定性定语从句:从句既可以修饰先行词,也可以修饰整个句子或句子的一部分.

答案与解析：
1. A. 主语与run(延伸)是主动关系,所以用现在分词.Those指街道,所以不用who而用that来引导定语从句.
2. B. 因为在此题中where引导定语从句,表示“在这种种况下”,与in which相当.
3. A. 因为先行词是Beijing而不是this autumn所以用where引导定语从句.
4. B. 答案B是省略了关系代词that的定语从句,另外,to后还省略了动词原形paint.
5. C. 因为of which引导定语从句,并在从句中作定语.of which the telephone number = whose telephone number.
6. D. 因为这是个非限制性定语从句,先行词是前面一句话的内容.
7. B. 因为表示“阶段、程度、地步”的the point在定语从句中作地点状语,所以用where引导定语从句.
8. B. 因为先行词是research centers并在定语从句中作状语,所以用where.
9. C. 因为当先行词是表示事物的all, little, few, much, anything, everything, nothing等时,多用that引导定语从句.
10. 因为先行词是the time,且在定语从句中作状语,所以用when引导.此题的先行词与定语从句被主句谓语分开了,要善于辨别.
11. B. 先行词是Taiwan is a part of China整个主句,一般由as或which引导定语从句,但which引导的定语从句只能放在主句之后,另外,as有“正如”之意,而which没有,所以用as.顺便说说,原句改为：It is known to everybody that Taiwan is…= What is known to everybody is that Taiwan is…
12. A. 两空都是考查定语从句,先行词分别是the day和Shen Zhou V was launched, the day在定语从句中作状语,用when引导；后句是非限制性定语从句,不能用that,要用which.
13. A. 因为替代不可数名词 (the bread) 只能用that,排除B和D；又因为先行词that (the bread) 在定语从句中作buy的宾语,用which,所以选A.
14. D. 当定语从句的先行词前有such, so, as等词语时,由as引导,并且as在定语从句中作主语或宾语,as在此题中作dream of的宾语.注意：在表示“如此…以致…”的such /so…that…结构中,that不作任何句子成份.
15. B. 考查非限制性定语从句,all of whose homes = all of their homes他们所有的房子.
16. D. 因为先行词是前面整个句子,且在从句中作主语,所以用which.of course是插入语.
17. D. 将疑问句改为陈述句：this research center is…显然缺少先行词,必须加上代词the one来作先行词,又因定语从句不缺主语或宾语,所以用关系副词where.假若在this后加the,就选where,请想想这是为什么.
18. A. 因为先行词是the days,并在定语从句中作状语.
19. B. 当先行词前有so时,用as引导定语从句,as在从句中作主语或宾语.假若在lift后加上it,答案就是that了,请想想这是为什么.
20. C. 因前后均的句子,必须要选连词,排除B和D；又因在介词后不能用that来引导定语从句,所以选C.during which time在那段时间里.

这取决于动词是否是及物动词.
比如：I must find a place to stay.
stay就不需要介词,因为是及物动词.
