who[英][hu:][美][hu]
pron.谁; 什么人; 关系代词，有先行词; 孰;
一、强调句型的用法
在英语中，我们常用It is／was… who/that结构来突出强调句子的某一成分。在这个句型中，it没有词汇意义，只是引出被强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它成分，则一律用that来连接。
E.g. It is my mother who／that cooks every day.
E.g. It was yesterday that Tom passed in the maths exam．
二、使用本句型的几个注意事项
1．被强调成分是主语，who／that之后的谓语动词应该在人称和数上与原句中的主语保持一致。
e.g. It is I who am right． e.g. It is he who is wrong．
e.g. It is the students who are lovely．
2．即使被强调成分是句子中的时间状语，地点状语，原因状语等，也不能用when，where, because，要用 that。
E.g. It was after the war was over that Einstein was able to come back to his research work again .
E.g. It was in front of the bank that the old lady was robbed．
E.g. It was because of the heavy rain that he came late．
3．如果被强调的成分有同位语，同位语也应提前。
It was from him，his chemistry teacher，that Paul learned to watch carefully in class．
4．被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格。 It was he that helped me yesterday. It was me that he helped yesterday.
5．被强调部分既包括人又包括物，用that不用who
lt was the things and people that they remembered that they were talking about．
三、考试中，为了增加试题难度，强调句型经常以疑问句形式出现。其一般疑问句形式是：
Is／Was it+被强调成分+who／that
Is it Mr.Smith who teaches you English?
其特殊疑问句形式是：疑问词+is／was+被强调成分+that...
Why was it that you did not attend the meeting yesterday?
When was it that this traffic accident happen?
Where was it that you put my English dictionary?
四、区分定语从句和强调句型某些定语从句和强调句型形式差不多，容易混淆。如果去掉it is／ was ... that句子仍然通顺成立，则为强调句型，不成立不通顺，则为定语从句。
E.g. It was three years ago that he went to American for a further study·
去掉It was that句子为Three years ago he went to America for a further study．句子通顺，意思完整，那么，这就是一个强调句型。
it is...that/who...用作强调句时，不作句子成分，也就是说去掉it is that 句子还是能够单独使用。这是和定语从句的区别。还用that引导的名词性从句也是这样的。 下面讲下强调句型：
1. 强调句型特点是：去掉It be …that/who…，句子成分完整。
It is in the street that I met her 强调句 把it is that 去掉，句子完整，in the street I met her. It is clear that not all boy like foot ball，去掉后，clear not all boy like football不完整，不是强调句（是主语从句）
2. 强调句中只有that/who/whom,不会出现where，which, when等。
It is the street where I met her 定语从句 where 关系副词 做定语从句中的地点状语；
3. 如果强调时间地点 就看前面有没有介词, It is in the morning/at some place that.......一般情况下就是强调
判断是否是强调句一般用以下方法：
把 It is/was ……that 去掉，看句子是否完整，若完整，则为强调句，若不完整，则为从句。 例：It was at the school gate that I met an old friend of mine.
It was the school gate where I met an old friend of mine. （定语从句）
用who连接下列句子
1.The manager was interrupted by a girl who came in with an envelop.2.My modern house looked strange to my sister who came to stay with us for a month.3.Jane never dreamed of receiving a letter from a girl who lived on the other side of the world.
who在句子中间怎么翻译
1.谁， 什么人 Who is that woman in the red hat?那个戴红色帽子的女人是谁？I wonder who will play in the basketball match.我不知道这场篮球赛谁会上场。
2.（限制性关系代词）…人 He who laughs last laughs best.最后笑的人笑得最开心。
All who[that] heard him were delighted.所有听了他讲话的人都很高兴。
He is the only one who[that] knows Russian.他是我们中间惟一懂俄语的人。
3.（非限制性关系代词）他， 她， 他们 The committee, who were all young women, fulfilled their duties admirably.委员会的委员们都是些年轻妇女， 很好地履行了她们的职责。
请问句子中who的用法
全部可以合并成定语从句；The man who is standing under the tree is my brother.The book which is on the table is mine.The girl who was wearing a hat was from America.There are the flowers which I bought for you.This is the picture which I took last week.
请问,who在英语句子中怎么用？
你这个句子中单词“is”应该是has吧，这里应该是现在完成时（现在完成时的主要用法之一是指动作发生在过去一直持续到现在可能会继续；用法之二是指动作发生在过去，刚刚完成，强调对现在的影响），表示到目前为止。
这个句子可以这样理解：句子的主干部分是：The problem has been widely discussed around the world.（这个问题在世界范围内广泛讨论。
）The problem （作主语；句子陈述的对象）has been widely discussed（作谓语动词；主语发出的动作既表示主语“是什么”或者“做什么 ”）around the world（作地点状语，修饰整个句子）而that who should take the responsibility of the healthy lifestyle 这个从句是对The problem 的解释说明，指出The problem （这个问题）的具体内容————that who should take the responsibility of the healthy lifestyle （谁应该为健康的生活方式负责）。
that who should take the responsibility of the healthy lifestyle 这是一个同位语从句，是对The problem 的解释说明，指出其内容。
that在同位语从句中不作任何成分，只起连接作用。
在同位语从句that who should take the responsibility of the healthy lifestyle 中，who作主语， should take 作谓语动词，the responsibility of the healthy lifestyle 作宾语（主语发出的动作的承受者）。
