初中英语语法三大从句在初中英语中，主要有三大从句，即宾语从句、定语从句、状语从句(包括时间、条件、结果、目的、原因、让步、地点、方式等)。
小编今天跟大家分享的就是这三个从句的主要语法点，赶快看起来吧!初中英语语法三大从句宾语从句一、定义在句子中起宾语作用的从句叫做宾语从句。
二、连接词that: I think that you can pass the exam.Whether/if: I don’t know what the word means.“Wh”: I don’t know what the word means.I don’t know where he found the book.只用whether的情况：1. 与or not连用：I don’t know whether it’s raining or not.2. 与动词不定式连用：He doesn’t know whether to accept the invit ation.3. 连接词前有介词时：It depends on whether he is coming.三、时态1. 主句是一般现在时态，从句根据实际情况而定(各种时态均可)She wants to know what he has done for the exam.2.主句是一般过去时态，从句用相应的过去的时态。
1)She said that she was a student.2)She said that she would fly to Japan in a week.3)She said that she had finished her homework already.3. 如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。

in case 用法
in case 用法收藏in case万一。
是连词，引导条件状语从句。
也就是说in case后面是一个完整的句子Take a hat with you in case the sun is very hot. 倘若太阳很利害，你就把帽子戴上。
in case of的of是介词，介词后面只能带名词性质的词，比如名词、代词等。
意思和in case 差不多，万一的意思In case of rain they can't go. 万一下雨，他们就不能去了。
in the case of，就...来说, 关于。
意思跟上面两个不一样了。
一般表示转而提及另一件事情。
比如In the case of woman，they have more difficulty in their job。
就女性来说，她们在工作中会遇到更多的困难in this case:在这个场合in that case:（短语）若是那样的话例：YOU don't like this place? In that case, why don't you leave?=====================（一）in case作短语连词，能引导状语从句。
就其词义和语法职能来分，可引导两种从句。
其一：in case ／just in case引导目的状语从句作“以免，以备，以防”等解。
如：He takes a torch in case it gets dark before he returns．他带了手电筒，以备天黑以后回家之用。

英语语法：状语从句八大类型的区分以及知识点讲解
英语语法：状语从句八大类型的区分以及知识点讲解NO.1 副词作状语(1)句子副词：句子副词用于修饰句子(而不是修饰某个单个的词)，反映说话人的观点和看法。
如actually, apparently, certainly, clearly,definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly 等。
作用以及位置：句子副词通常位于句首(或分句句首)。
Eg:Obviously he can't tell the difference between them. 显然他无法区别两者的不同。
I arrived late but luckily the meeting had been delayed. 我迟到了，幸而会议推迟了。
但有些句子副词也可以出现句中。
eg：He smiled nastily. He evidently knew something I didn't. 他发出狞笑，他显然知道一些我所不知道的事。
有的句子也可用作其他种类的副词，不过这往往会导致位置和语义的变化：Clearly he didn't say so. 显然他没有这样说。
(句子副词)He didn't say so clearly. 他说得没有那么清楚。
(方式副词)(2)起连词作用的副词连接副词就是连接词，如besides，meanwhile，then, therefore, thus, However,Otherwise, so, yet 等。
作用以及位置：常放在两个句子中间，前面为逗号，后面放连接词，从句之前。
注意：so 也可放在形容词之前做修饰，yet 可放句尾或从句之前。

in case 的用法
in case 的用法一、"In case"的用法简介"In case"是一个常用的短语，在英语中有多种不同的用法和含义。
它可以用作副词短语，表示“以防万一”，也可以用作连词短语，引导条件从句。
本文将主要讨论"in case"作为副词短语时的用法及相关注意事项。
二、表示“以防万一”的字面意义"In case"通常用来表示在某种情况下采取措施或做某事，以应对可能发生的事件或问题，从而避免不必要的麻烦或困难。
例如：1. I always carry an umbrella in case it rains.以防下雨，我总是带着伞。
2. Please bring your passport with you, just in case.请随身带上你的护照，以备不时之需。
这种用法强调预见和预防，并且在很多情况下意味着提前做好准备。
它可适用于各个场合，如旅行、工作、日常生活等等。
然而，在使用时需要注意以下几点：三、使用"in case"的注意事项1. 宾语从句的虚拟语气当"in case"后面跟宾语从句时，如果主句是将来时，从句要使用与现在事实相反的虚拟语气。
例如：Take a map with you in case you get lost.以防你迷路，请随身带一张地图。
这里，“you get lost”表示将来可能发生的情况，但仍然使用了一般现在时的虚拟语气。
2. 可能性和预测"In case"常常用来表达某种可能性或对未来情况的有根据的预测。
尽管这并不意味着这种情况一定会发生，但我们作出某种准备或采取措施是有道理的。
例如：I'll take some snacks in case we get hungry on the trip.我带些零食，以防我们旅途中饿了。

2.in this case: 在这个场合3.in that case: 若是那样的话例：You don't like this place? In that case, why don't you leave?（五）In case 的其他问题：1. 连词In case与for fear that目的：in case作“以防、以免”引导目的状语从句时，相当于for fear that 引导的表示原因的从句，可以通用。
例如：a.I wrote it down in case/ for fear that I should forget it. 我已把它抄下了，免得忘记。
b.I must stay at home this morning in case/for fear that he comes to see me. 我今天上午必须呆在家里，恐怕他会来看我。
（不期而至）2. 介词In case of 与for fear of介词宾语不同：作“提防”，“惟恐”这个意思讲，in case of 和for fear of 是同义词，但不一定能通用：in case of 只引导名词，for fear of 多半引导动名词短语。
例：a.In case of fire, break the bottle. 如果发生火灾，请把瓶打破。
（条件状语）b.I always put some money in my pocket in case of need. 我总是要在口袋里放一点钱以备需用。
（目的状语）c.We came here for fear of being fined. （目的/原因状语）3. 连词In case与if语气：if引导条件状语句时，可用虚拟语气；in case引导条件状语句时，常用于陈述句，不常用虚拟语气，且意思不太一样：a.If I were to ask for leave, would she agree? 如果我请假，他会答应吗？b.In case I ask for leave, will she agree? 如果我请假，她会答应吗？主将从现：in case 引导的条状从和if真实条件句一样，遵循“主将从现”原则。
例：a.In case the weather is fine tomorrow, we shall hold a meeting. 如果明天天气好的话，我们将召开一次会议。
b.Henry will resign in case you drive him too hard. 如果你欺人太甚的话，亨利就会辞职不干。
