Answer 1

这里的which指的是sanctions，即制裁的意思。
一、定语从句的定义。
用作定语的从句叫做定语从句(attributive clause)。定语从句通常皆置于它所修饰的名词(或代词)之后，这种名词(或代词)叫做先行词(antecedent)。引导宾语从句的关联词为关系代词和关系副词。关系代词在定语从句中可用作主语、宾语、定语等;关系副词在定语从句中只用作状语。如：
The student who answered the question was John. 回答问题的那个学生是约翰。(who answered the question是关系代词who引导的定语从句，用以修饰who先行词student，who在从句中用作主语)
I know the reason why he was so angry. 我知道他这么生气的原由。(why he was so angry是关系副词引导的定语从句，用以修饰why的先行词reason，why在从句中用作原因状语)
定语从句一般紧跟其先行词之后。如：
The room which served for studio was bare and dusty. 这个用作工作室的房间空荡荡的，布满灰尘。(关系代词which引导的定语从句紧跟其先行词room之后)
有时亦可与先行词分离。如：
A new master will come tomorrow who will teach you German. 明天要来一位新教师教你们德语了。(关系代词who引导的定语从句与其先行词master分离)
二、关系代词的用法。
用作关联词的关系代词有who，whom，whose，that，which等。who，whom，whose指人，who是主格，在从句中用作主语(在非正式英语中亦可用作宾语);whom是宾格，在从句中用作宾语;whose是属格，在从句中用作定语(有时亦可指物)。如：
The man who was here yesterday is a painter. 昨天在这里的那个人是位画家。(主格关系代词who在从句中用作主语)
The man who I saw is called Smith. 我见到的那个人名叫史密斯。(在非正式英语中who 代替了whom，亦可省去不用)
I know the man whom you mean. 我认识你指的那个人。(宾语关系代词whom在从句中用作宾语)
A child whose parents are dead is called an orphan. 失去父母的孩子叫做孤儿。(属格关系代词whose在从句中用作定语，指人)
I’d like a room whose window looks out over the sea. 我想要一个窗户面临大海的房间。(属格关系代词whose在从句中用作定语，指room，可代之以of which，但后者较为正式)
that在从句中既可用作主语，亦可用作宾语（在非正式文体中可省去）；既可指人，亦可指物，但在当代英语中多指物。如：
A letter that is written in pencil is difficult to read. 用铅笔写的信很难读。(关系代词that在从句中用作主语，指物)
The letter that I received from him yesterday is very important. 昨天他来的信很重要。(关系代词that在从句中用作宾语，指物)
Is he the man that sells eggs? 他是卖鸡蛋的那个人吗?(关系代词that在从句中用作主语，指人)
关系代词which在从句中可以用作主语和宾语，一般皆指物，在非正式文体中可以省去。
This is the book which has been retranslated into many languages. 这就是那本有多种译本的书。(关系代词which在从句中用作主语)
Where is the book which I bought this morning? 今天上午我买的那本书在哪儿?(关系代词which在从句中用作宾语，可省去)
which在从句中亦可用作定语和表语。如：
We told him to consult the doctor, which advice he took. 我们叫他去看医生，他听取了我们的劝告。(关系代词which在从句中用作定语)
The two policemen were completely trusted, which in fact, they were. 那两个警察完全受到信任，事实上真是如此。(关系代词which在从句中用作表语)
as，than，but亦可用作关系代词。如：
The two brothers were satisfied with this decision, as was agreed beforehand. 两兄弟对这个决定都满意，它事先已经他们同意了。(关系代词as在从句中用作主语，其先行词是this decision)
He was a foreigner, as I knew from his accent. 他是个外国人，我是从他的口音知道的。(关系代词as在从句中用作宾语，其先行词是前面的整个句子)
I never heard such stories as he tells. 我从未听过他讲的这类故事。(关系代词as与指示代词such连用，在从句中用作宾语，其先行词是such stories)
Her attitude to him was quite the same as it had always been. 她对他的态度同她惯常的态度完全一样。(关系代词as与指示代词same连用，在从句中用作表语，其先行词是same)
You spent more money than was intended to be spent. 你花的钱超过了预定的数额。(关系代词than在从句中用作主语，其先行词是money)
There are very few but admire his talents. 很少人不赞赏他的才干的。(关系代词but在从句中用作主语，其先行词是few，but=who don’t)
关系代词在定语从句中用作介系词的宾语时，介系词既可置于从句之首，亦可置于从句之末。但以置于从句之首较为正式。当介系词置于从句之首时，如果先行词指人，就只能用whom，先行词指物，只能用which，如果先行词在从句中作定语，表示所属概念，则用whose。如：
This is the book for which you asked. 这是你所要的书。(关系代词用作介词for宾语，之首，即which之前)
This is the book which you asked for. 这是你所要的书。(介词for置于从句之末，which在此可省去)
关系代词who和that用作介词宾语时，介系词须置于句末。如：
The people who you were talking to are Swedes. 你与之谈话的那些人是瑞典人。(关系代词主格who用作介词to宾语时，介词to须置于从句之末，who中口语中可省去)
Here is the car that I told you about. 这儿就是我和你谈过的那辆汽车。(关系代词that用作介词about宾语，介系词about须置于从句之末)
有时从句还有其它成分，介系词则置于从句之中，但不能置于从句之首。如：
This is the boy who he worked with in the office. 那就是与他一道办公的那个男孩。
先行词指人时，关系代词既可用who，亦可用that。但关系代词在从句之中用作主语时，多用主格who。如：
Persons who are quarrelsome are despised. 好争吵者遭轻视。(除persons外，还有people，those，等皆多用who)
All who heard the story were amazed. 听到这个故事的人都感到吃惊。(代词如he，they，any，all，one等之后多用who)
I will pardon him who is honest. 我愿意宽恕他，他是诚实的。(描述性定语从句用who)
I think it is you who should prove to me. 我认为是你应该向我提出证据。(在强调结构中多用who，who在此可省去)
Who is not for us is against us. 谁不赞成我们就是反对我们。(缩合连接代词who为可代之以that)
在下列一些情况中则多用that。如：
)He was the man that the bottle fell on. 他就是瓶子落在其身上的那个人。(此处常用that作宾语指人，亦可用whom)
He is a man that is never at a loss. 他是一个从未一筹莫展的人。(that常用于泛指人)
He was watching the children and parcels that filled the car. 他望着塞满车的孩子和包裹。(兼指人与物时须用that)
Who that you have ever seen can beat him in chess? 你曾见过谁能在棋艺上打败他?(避免与先行词who重复时应用that)
That’s the same man that asked for help the day before yesterday. 这个与前天求援的是同一个人。(先行词前有指示代词same时应用that)
He is not that man that he was. 他已不是过去的他了。(that常用作表语)
I knew her father for the simplest, hardest working man that ever drew the breath of life. 我早知她的父亲是一个世上最简朴最努力工作的人。(先行词前有形容词最高级、序数词或only等词时应用that)
先行词指物时，关系代词that与which往往可以互换。但在下列情况中多用that。如：
All that glitters is not gold. 闪光的东西不都是金子。(不定代词包括复合词something等多后接that)
It was the largest map that I ever saw. 那是我所看见过的最大的地图。(前有形容词最高级等的先行词之后多用that)
It was liberation that brought about a complete change in his life. 是解放给他的生活带来了彻底的改变。(强调结构用that)
There is a house that has bay windows. 有一栋房子有凸出的窗户。(that在此表固有的特点)
The distance that you are from home is immaterial. 你离家的距离是不足道的。(在限制性定语从句中关系代词用作表语应用that，在描述性定语从句中则应用which)
Which was the hotel that was recommended to you? 哪一个是推荐给你的旅馆?(这里用that显然是为了避免重复which)
在下列情况中则多用which。如：
Larry told her the story of the young airman which I narrated at the beginning of this book. 拉里把我在书本开关叙述过的那个关于一个青年飞行员的故事讲给她听。(离先行词较远时常用which)
A store should keep a stock of those goods which sell best. 商店应存在最畅销的货物。(“those+复形名词”之后多用which)
I have that which you gave me. 我有你给我的那个。(which比较正式，在非正式英语中也可用that)
Beijing, which has been China's capital for more than 800 years, is rich in cultural and historic relics. 北京曾是八百多年的中国首都，有很丰富的历史文物。(描述性定语从句一般皆用which)
This is the one of which I’m speaking. 这就是我所讲的那个。(介系词之后须用which)
希望我能帮助你解疑释惑。

Answer 2

which就是指代“the UN Security Council lifted sanctions on Eritrea”，联合国撤销了对厄立特里亚的制裁。were imposed指的就是联合国对Eritrea施加的仲裁。

Answer 3

可以引导定语从句,宾语从句,主语从句。

I bought a room yesterday,which used to belong to Tom.(定语从句）

I don't know which one I should buy.（宾语从句）

Which bus we should take is still a question.(主语从句）

which 在定语从句中可以做主语和宾语.做表语只能用that.

如：I found the book which he sent me two years ago.which 做 send sb sth 中的宾语成分 I found the book which belongs to Mary.which 替代book。

做从句的主语： which 在宾语从句和主语从句中和后面的名词一起构成句子中的成分.Which bus we should take is still a question.中和bus 一起做take的宾语.

Answer 4

联合国安全理事会解除对厄立特里亚的制裁。2009年，厄立特里亚因涉嫌支持索马里武装部队遭到制裁。
which指代厄立特里亚，were imposed = were imposed sanctions被实施制裁

Answer 5

从该非限制性定语从句中的谓语动词 were，就能看出 which 指代的当然是主句中的 sanctions追答

impose在句中做及物动词，sanctions 和 impose 之间是被动关系，意思就是“制裁被(强制)执行/实行”
