定語從句中that和who用法的區(qū)別
that和who在定語從句中的用法幾乎相近，因此，在that和who運(yùn)用中時(shí)常出錯(cuò)。下面是小編為大家推薦定語從句中that和who用法的區(qū)別，希望能夠幫助到你，歡迎大家的閱讀參考。
在定語從句中，關(guān)系代詞who (whom) 和that都可指人和物，在一般情況下，可以互換使用，但在下列情況下值得注意：
一、用who (whom) 而不用that的情形
(1) 在非限制性定語從句中的先行詞指人時(shí)，只能用who (whom).如：
My sister，who is studying abroad，sent me a beautiful present just before this Christmas.我姐姐，她在國(guó)外學(xué)習(xí)，就在圣誕節(jié)前給我寄來了漂亮的禮物。
(2) 當(dāng)定語從句對(duì)指人的先行詞進(jìn)行隔位修飾時(shí)，只能用who (whom).如：
Do you know the girl in front of the blackboard who is speaking to the students?你認(rèn)識(shí)黑板前面正在給學(xué)生們講話的那位女孩子嗎?
(3) 當(dāng)先行詞為people和those時(shí)，只能用who (whom).如：
Those who want to go there come here please.那些想去那兒的人請(qǐng)來這邊。
(4) 當(dāng)先行詞為one，ones，anyone，everyone，none，all(指人) 時(shí)，只能用who (whom).如：
Anyone who is against us is our enemy.任何反對(duì)我們的人就是我們的敵人。
(5) 先行詞指人，而關(guān)系代詞在從句中作主語時(shí)，一般多用who。如：
The man who came here yesterday said he would come again in a few days.昨天來這兒的那個(gè)人說過幾天他會(huì)再來。
(6) 在there be句型中名詞的定語從句多用who (whom)。如：
There are students in our class who / whom you have met.我們班有些學(xué)生你見過。
(7) 當(dāng)句子中有兩個(gè)指人的現(xiàn)行詞分別帶有兩個(gè)定語從句時(shí)，若一個(gè)定語從句的引導(dǎo)詞為that，那么，另一個(gè)定語從句的引導(dǎo)詞必定為who。如：
The boy that you met just now is Li Ming’s brother who just graduated from a university.剛才你會(huì)到的那個(gè)男孩是李明的剛從大學(xué)畢業(yè)的弟弟。
二、用that 而不用who (whom)的情形
(1) 當(dāng)先行詞前面有形容詞的最高級(jí)或序數(shù)詞修飾時(shí)，引導(dǎo)詞只能用that。如：
The tallest player that plays football for our team is from Shandong.在為我們隊(duì)踢足球的最高哪個(gè)運(yùn)動(dòng)員來自山東。
(2) 當(dāng)先行詞前面有only，some，any，no，every，little，few，much，all，very形容詞修飾時(shí)，引導(dǎo)詞只能用that。如：
He is the only student that said “no” to the teacher.他是唯一的一個(gè)對(duì)老師說“不”的學(xué)生。
(3) 當(dāng)主句是以who開頭的特殊疑問句時(shí)，引導(dǎo)詞只能用that。如：
Who is woman that you talked with just now?剛才跟你談話的那位婦女是誰?
(4) the same as 與 the same that
the same as所引導(dǎo)定語從句的內(nèi)容與先行詞同類而不同物；the same that表示所引導(dǎo)的從句內(nèi)容與先行詞同類同物，即：同一事物.如：
She is wearing the same coat that I lost a few days ago.她正穿著我?guī)滋烨八鶃G失的上衣。
She is wearing the same coat as I lost a few days ago.她正穿著跟我?guī)滋烨八鶃G失的上衣同樣的上衣。
who和that 的定語從句
指人可用that who, 以下情況多用who;
Those people做先行，There be的結(jié)構(gòu)中;
例句：
1) Those who are for the plan, please raise your hands.
贊成計(jì)劃的人請(qǐng)舉手。
2) People who create computer viruses are called hackers.
制造電腦病毒的人被稱為黑客。
3) There was once a little boy who came to the net bar to play games every night.
曾經(jīng)有一個(gè)小男孩每天晚上都來網(wǎng)吧玩游戲。
先行指人不定代，從中做主who要在：
先行詞是指人的不定代詞，如 one 、someone 、anyone 、nobody 等詞，或指人的關(guān)系代詞在定語從句中做主語，要用who, 而不用that。
例句：
1)Nobody who knows a little scientific knowledge will believe you.
懂得一點(diǎn)科學(xué)知識(shí)的人都不會(huì)相信你的話。
解析：nobody是指人的.不定代詞，用who, 不用that。
2)The thief who pretended to be a manager was caught stealing a car.
那個(gè)裝扮成經(jīng)理的賊在偷車時(shí)被當(dāng)場(chǎng)抓獲。
解析：who指人，在定語從句中做主語。
兩個(gè)定從一起來，不要重復(fù)你有才：一個(gè)先行詞有兩個(gè)定語從句時(shí)，關(guān)系代詞要避免重復(fù)使用。
A plant that can cure diseases, which was known by the ancient Chinese , is called Chinese herbal medicine. 一種能夠治病的，被古代中國(guó)人所熟知的植物，叫做中藥。
定語從句中who和that的用法有什么區(qū)別
1. 兩者均可指人，有時(shí)可互換(包括當(dāng)先行詞為 all, anyone, someone等，同時(shí)也包括先行詞受the only等的修飾時(shí))：
All that [who] heard him were delighted. 所有聽了他講話的人都很高興。
He is the only one among us that [who] knows Russian.他是我們中間唯一懂俄語的人。
Anyone who [that] is over sixteen is allowed in. 任何超過十六歲的人都允許進(jìn)去。
It is impolite to turn your back on someone who [that] is speaking to you. 人家跟你說話，你把背朝人是不禮貌的。
2. 但是在下列情況，通常要用 that：
①當(dāng)先行詞是一個(gè)既指人又指物的并列詞組時(shí)：
I made a speech on the men and things that I had seen abroad. 我就我在國(guó)外所見到的人和事作了報(bào)告。 ②當(dāng)先行詞是who時(shí)(為避免重復(fù))：
Who was it that won the World Cup in 1982? 誰贏得了1982年的世界杯?
③當(dāng)關(guān)系代詞在定語從句中作表語時(shí)(可省略)：
Tom is not the boy (that) he was. 湯姆這孩子已不是以前那個(gè)樣子了。
3. 但是在下列情況，通常要用 who：
當(dāng)先行詞為 those 且指人時(shí)，英語習(xí)慣上要用 who 來引導(dǎo)定語從句。如：
Those who do not wish to go need not go. 不愿去的人不需要去。
Those who couldn’t walk were carried on stretchers. 那些不能走的人都用擔(dān)架抬著。
It is said that eat the most are the least healthy. 據(jù)說吃得最多的人身體最差。
Only had booked in advance were allowed in. 只有那些預(yù)先訂票的人可以進(jìn)去。
The plan was supported by those who wished to listen to more good English. 這計(jì)劃受到想多聽好英語的人的支持。
Let us spenda few moments in silence so that / in order that we remember died to preserve our freedom. 讓我們默哀片刻，以緬懷那些為維護(hù)我們的自由而犧牲了的人們。
注：偶爾也可見到在 who 之后用 that 引導(dǎo)定語從句的用例，但相當(dāng)少見。如：
The danger is that people who pay their bills on time will be lumped in with those that don’t. 危險(xiǎn)的是那些及時(shí)付賬的人將會(huì)同那些不及時(shí)付賬的人混在一起。
