浅谈that在从句中的用法
that在从句中的用法
that在从句中的用法在英语中，"that"是一个常用的代词，可以在从句中作为主语、宾语、表语或同位语使用，表示特定的事物或概念。
以下是一些常见的"that"在从句中的用法：1. 主语从句：在主语从句中，"that"常被省略，但如果引导的主语太长或与主句的主语不同，通常会保留"that"。
例如：“That (that) he is a good teacher is clear.”2. 宾语从句：在宾语从句中，"that"可以省略，尤其是在某些动词（如"think"，"believe"等）后。
例如：“I believe (that) she will succeed.”3. 表语从句：在表语从句中，"that"通常不省略。
例如：“The reason why he was late was that he missed the bus.”4. 同位语从句：在同位语从句中，"that"不作任何成分，因此通常省略。
例如：“The news that he won the prize was exciting.”5. 关系代词：在定语从句中，"that"作为关系代词，可以指人或物，代替先行词在从句中充当成分。
例如：“The book that I read was very interesting.”6. 强调结构：在强调结构中，"that"用于强调某个特定的部分。
例如：“It was she that (that) found the lost child.”需要注意的是，"that"在从句中的用法可能会因为语境、习惯或避免重复而有所不同。
因此，在实际使用中，需要根据上下文和语法规则来判断是否省略"that"。

that的用法
that的用法That是一个非常重要的英语小词，却又有很多的用法，学习者有时候会感到很困惑，为了帮助大家更好地掌握that的用法，在下面我们将一一为大家讲解that的用法及其注意事项，希望能够帮助大家有效地学习。
That可以用来引导形容词性从句，在句中充当主语或宾语，例如：I think that the soccer game will be interesting. (我认为足球比赛会很有趣)。
That也可以用来引导名词性从句，例如：I know that you are busy. (我知道你很忙)。
此外，that还可以做连词，引导一个并列句，例如：She is good at dancing and that she is talented in writing. (她舞跳得很好，也有文字创作的天赋)。
另外，在口语中，人们也经常用that来替代其他句子成分，例如：He said (that) he was coming. (他说他会来)。
但是，在书面语当中完全可以不用that，但是有时候不加that也就不能表达出想要表达的意思，特别是在表明方位或时间时，that是必不可少的，例如：He left at 11:00 that morning. (他那天早晨11点离开)。
在宾语从句中，如果从句需要介词时，使用限定性that，例如：I like the way that you talk. (我喜欢你说话的方式)。
此外，在某些例句中，that可能和which、who、whom混淆，例如：He is the one who (that) I love. (他就是我所爱的人)，Which/Who/Whom都可以填入，但是who/whom只用于人，而which只用于物。
最后，要特别指出的是，that也可以用来引导一个定语从句，例如：This is the book that I am looking for. (这就是我正在找的书)，定语从句通常是对名词或者代词的解释或补充，that在定语从句中一般是省略不写的。

定语从句只用that的八种情况1. 当先行词是不定代词的时候就得用that 啦，比如说“All that glitters is not gold.”（发光的不都是金子呀。
）2. 先行词被序数词修饰的时候，那肯定得是 that 呀，就像“ The first thing that I want to do is to take a rest.”（我想做的第一件事就是休息一下。
）3. 先行词被形容词最高级修饰时，只能用 that 哦，例如“ This is the best movie that I have ever seen.”（这是我看过的最好的电影呢。
）4. 先行词既有人又有物的时候，不用that 还能用啥呢，像“ They talked about the persons and things that they remembered.”（他们谈论着他们记得的人和事呀。
）5. 当先行词被 the very，the only 等修饰时，那就是 that 没跑啦，比如“This is the very book that I am looking for.”（这就是我正在找的那本书哟。
）6. 当主句是以 who 或 which 开头的疑问句时，后面不也得是 that 嘛，像“ Who is the man that is standing there?”（站在那儿的那个男人是谁呀？）7. 当先行词在定语从句中作表语时，肯定得选 that 呀，例如“ China is not the country that it was.”（中国已不是过去的中国了。
）8. 当先行词是数词时，也得用 that 呀，像“ Three people died in the accident that happened yesterday.”（在昨天发生的事故中有三人丧生。

因此，同学们在使用that这个单词时，总会出现这样那样的问题，特别是that在从句中的使用,更是令同学们常常模棱两可，分辨不清。
但考试中又常出现，让我们和学生都比较头痛。
我觉得要解决这个问题，首先要让学生弄清that在所引导的从句中它的词性，然后结合实例分析，这样学生就可一目了然了。
具体来说，that可作连词或关系代词。
具体的作用如下：一．that引导主语从句(subject clauses)，在句中充当主语的成分。
that在句中无实义，但放在句首时不能省略：a．that the attempt to save her had succeeded became widely known. b．that they did not tell us about their problems is a pity.这种结构主要是对that从句的内容进行强调，属正式文体，that the attempt to save her had succeeded和that they did not tell us about their problems在句中都分别作了主语。
但为了避免显得头重脚轻，常把that从句移到句子后面，而把it放在句首，作形式主语，此时that可以省。
上面两个句子就可改为:a. it is widely known (that) the attempt to save her had succeededb. it is a pity (that) they did not tell us about their problems.如果整个句子是疑问形式，就只能用先行it结构,例如：a. is it true that he would take the risk ?b. is it possible that they will come tomorrow ?在主语从句中，常使用先行it结构，用that从句作主语的句子主要有下列几个句型：(1)、it + be + 形容词+ that从句：it is necessary that you come to school every sunday.it’s strange that she should gain the full marks.(2)、it + be + 名词词组+ that从句：it’s a great pity that you such a stupid idea that day.(3)、it + 及物动词+ 宾语+ that从句：it worried her a bit that she became fatter and fatter.it shocked me that peter didn’t tell anybody where he was.(4)、it + be + 过去分词+ that从句：it is said that he has been there many times.(5)、：在一些谓语动词为不及物动词（如：appear，happen，seem，turn out等）的句子中，主语从句也后置，而把it放在句首，作形式主语。
it happened that i saw your brother yesterday。
it seems that he has lost something.注意：在上述第(1)和第(2)两种句型中，that从句前置与使用先行it，that从句后置在意义上没有什么差异；但使用先行it结构较为常见。
二。
that引导宾语从句(object clauses)，放在动词、介词和一些表示人的感情或情绪的形容词后面，在句中充当宾语的成分，口语中that常省略。
这类动词常为及物动词如say，tell，ask，think，declare，reply，require，etc；形容词如afraid，certain，glad，angry，aware，grateful，anxious，delighted，pleased，satisfied，surprised，sad，etc。
a. she said (that) she would come。
b. do you remember (that) he has ever told us an interesting story?c. i’m sorry (that) i can do nothing for you。
三. that 引导表语从句(predicative clauses)，放在联系动词后，在句中充当表语的成分。
此时that也无实义,但不可省。
例如：a. our wishes were that you leave here at once.b. my suggestion is that a few more people be sent there to help them. 要注意的是，当主语是the reason、the cause时，为了避免含义上的重复，其后的表语从句一般也不再使用because引导，而用that。
a. the trouble is that we are short of money。
b. the reason why he was late is that he missed the early bus。
四．that引导同位语从句(appositive clauses)，放在名词的后面，补充说明名词的内容等。
这种名词有fact，idea，belief，conclusion，confidence，doubt，duty，evidence，feeling，hope，idea，impression，information，knowledge，law，news，notion，opinion，order，proof，proposal，rule，suggestion，theory，thought，truth，view，etc。
此时that也无实义，但也不可省。
a. the fact that he failed in the exam made us surprised。
b. we are delighted at the news that our delegate won the first prize in the speech contest。
五．that引导目的状语从句(clauses of purpose)，如so…that，in order that，for fear that等；结果状语从句(clauses of result)，如so(such)…that，(so)that 等；条件状语从句(clauses of condition) ，如：provided that，on condition that, supposing that等；原因状语从句(clauses of reason or cause)，如：now that等。
要区别so…that引导的从句到底是表结果的还是表目的的状语从句，一般情况可以看从句中是否有这样一些词：may，might，shall，should，can，could，will，would等情态动词。
如果有，该从句可判定为目的状语从句。
a．bring it nearer (so) that i may see it better (clause of purpose)。
b. his behavior was so bad that we all refused to receive him in our homes（clause of result）。
c. now that the weather has improved, we will be able to enjoy the game （clause of reason）。
d. he will lend you the money on condition that you return it in 6 months （clause of condition）。
六．引导名词性从句中的定语从句，而且只能是限定性定语从句。
（1）可指代人或物，在从句中作主语或宾语。
指物时可换为which,指人时可换为who (作主语，但who更常用)或whom(作宾语,在日常口语中常用that)。
作宾语时可省略。
a. the letter that/which came this morning is from my father。
b. here are the books ( that ) i borrowed last week.c. the woman (whom/that) spoke to me in the bookstore used to live next door.. 但如果有两个或两个以上分别表示人和物的先行词时(先行词既有人又有物)，定语从句的关系代词用which和who都不可以，只能用that。
a. we know nothing about the doctors and the hospitals that you are talking about.b. there are sheep and men that can be seen on the hill.(2) 当先行词是everything ，anything, nothing, somebody, the little, the few, much, all等不定代词时，定语从句由that引导。
a. anyone that wants to succeed must work hard。
b. the book contains a good deal that is boring and unnecessary 。
(3 )当先行词被形容词的最高级，序数词或the only, last, every, some, any, very, next,等修饰时，定语从句由that引导。
