初中英语中考考点之主将从现
初三英语中考语法考点重难点详解(七)状语从句的时态知识点整理总结(含主将从现)
初三英语中考语法考点重难点详解（七）状语从句的时态知识点整理总结（含主将从现）中考英语对状语从句的考查，主要集中在时间状语从句和条件状语从句，首先要知道状语从句的作用，描述主句动词发生的“样子”：发生的时间、地点、条件、原因等等。
1、主句是祈使句或者含有情态动词的现在式，这个时候，从句多用一般现在时，例如：He can pass the exam if he studis hard.Tell me if he comes.2、主句用过去进行时，从句用一般过去时，例如：Mom was cooking when I got home.She was praticing the piano when I called.这种情况本质就是过去进行时的功能：表达过去某个时间点正在发生的动作，而从句中的动词往往是个瞬间动词，这个动作的发生（如got home，called）刚好对应着过去的一个“时间点”。
3、主句从句都用过去进行时，这个时候连词用while，例如：While I was doing my homework, mom was cooking in the kitchen.I was sitting in the sun while wy wife was working in the garden.这种情况其实是考试连词while的含义：在……的过程中，这样从句的动词就需要一个“延续性”动词，才能和while 配合完美。
4、关于条件句的用法，是出题人最喜欢采用的If he comes, give him the picture.（主句是祈使句，天剑局是一般现在时）If we try our best, we'll get good grades.主将从现是一般原则，但是要注意也有很多不是主将从现的主从句配合。
补充知识点：“主将从现”首先我们知道一个句子的成分包含，“主谓宾定状补”，那么在句中作状语的从句称为状语从句。
2019年中考英语时态知识点：常见的主将从现的四种情况
2019年中考英语时态知识点：常见的主将从现的四种情况主将从现主将从现是指在时间状语从句和条件状语从句和让步状语从句中，如果主句是一般将来时，从句用一般现在时替代一般将来时。
主将从现常见的有以下四种情况：一、时间状语从句的主句是一般将来时，那么从句常常用一般现在时。
如：When I grow up, I’ll be a nurse and look after patients.我长大后要当一名护士，照顾病人。
二、如果主句是祈使句，那么从句通常要用一般现在时如：Don’t laugh at me when I make a mistake.我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时，根据需要从句多用一般现在时如：You should be quiet when you are in the reading room在阅览室时应保持安静。
四、如果if的条件状语从句遇到变换间接和直接时 , 祈使句应用not to....如; She said not to close the window常见的时间状语从句的连词有：as soonas,when,while ,as,until等主将从现说的是在含有时间状语从句和条件状语从句的主从复合句中，如果主句的时态是一般将来时，那么从句要用一般现在时。
例如：I will tell him about it when he comes.If it is fine tomorrow, we will go outing.如果主句的时态是过去将来时，那么从句要用一般过去时。
例如：He said that he would have another try if he had the chance.I knew he could help me if he was free the next day.主要标志有：if 、unless 、until、 when 、as soon as。
中考英语知识点：条件状语从句-主将从现
中考英语知识点：条件状语从句-主将从现中考英语知识点：条件状语从句-主将从现主将从现指if条件状语从句用一般现在时，主句用一般将来时。
e.g. If it doesn’t rain tomorrow, we’ll go to the Great Wall.如果明天不下雨, 我们就会去长城.If you don’t get up early, you will be late for school.如果你不早点起床, 你就会上学迟到.If I play games on it, it will go wrong.如果我用它玩游戏, 它就会坏掉.这里特别注意if条件状语从句与if引导的宾语从句之间的区别：He will call you if he comes back. 如果他回来，他会给你打电话。
（此句if表如果，是条件状语从句，所以用主将从现。
）I don’t know if he will come back. 我不知道他是否会回来。
（此句if表是否，相当于whether，引导宾语从句, 所以不遵循主将从现，应根据实际情况选择时态。
）补充：when也有相同的用法。
He will call you when he comes back. 当他回来的时候，他会给你打电话。
（此句when表当…时候，是时间状语从句，所以用主将从现。
）I don’t know when he will come back. 我不知道他何时会回来。
（此句when表什么时候，引导宾语从句, 所以不遵循主将从现，应根据实际情况选择时态。

主将从现 知识讲解 “主将从现”适用于什么样的从句中
主将从现知识讲解“主将从现”适用于什么样的从句中所谓的“主将从现”第一层次，即“主句用将来时（现在将来时和过去将来时），从句用一般时（一般现在时和一般过去时）”,这一层次也可以称作“初中层次”。
第二层次：“主将”中将来时有将来进行时，将来完成时，将来完成进行时，而“从现”中相应的时态也可能是现在进行时，现在完成时，现在完成进行时。
例如：If the snow has completely stopped, we will be playing with snow on the playground.如果雪能够完全停下来，我们将正在操场上玩雪呢！If it is snowing, we will have been walking in the snow for more than two hours.如果天一直在下雪，我们将在雪地里走了两个多小时了。
另外，引导条件状语从句的连接词（connector）还可以是unless, so long as, in case, on condition that, supposing that, provided that 等。
if引导条件状语从句的两种用法：第一种用法：当某事发生的可能性较大时，这种情况，有个十三字口诀：“主将从现，主过将从过，主现从现”。
即主句是一般将来时，从句用一般现在时；主句用过去将来时，从句用一般过去时；当主句中有can/can’t的话，则从句用一般现在时。
例如：If he has time, he will come tomorrow.If she finishes early, she can come back early.If you don’t do homework, the teacher will scold you.第二种用法：1.if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。

初中英语2024届中考语法复习状语从句知识讲解
中考英语语法复习状语从句知识讲解复合句由一个主句和一个或一个以上的从句构成，由连接词引导的句子是从句，另一句为主句。
在主从复合句中用作状语的从句叫作状语从句。
状语从句包括：时间状语从句、条件状语从句、原因状语从句、让步状语从句、结果状语从句、比较状语从句一、时间状语从句1.when 和 while 当……时1)when可以用来表示将来的某个时间会发生的事情或动作,主句用一般将来时,从句用一现在时(即"主将从现”)。
【例句】When spring comes, I'll work hard like you.当春天来临时,我将像你一样努力工作。
(由when引导的句子是从句,用一般现在时,spring是第三人称单数,用comes;另一句是主句,用一般将来时will work)特别提示:从句放在主句前面时,需要加逗号。
2) when 可以用来表示规律或客观真理,此时主句和从句都用一般现在时。
【例句】When water boils, it turns into steam.当水沸腾时,就会转变成水蒸气。
3)when 可以用来表示先后发生的两个动作,这两个动作都用一般过去时。
【例句】Lucy turned on the radio when she went back home.露西回到家就打开了收音机。
（露西回到家之后打开收音机,两个动作有先后）4)when可以用来表示一个动作(一般过去时)发生的时候,另一个动作(过去进行时)正在进行,此时 when 和 while可以互换使用。
【例句】When Ben was walking with Sam in the street, a motorcycle came towards Ben and knocked him down.当本和萨姆在街上走时,一辆摩托车冲过来,把本撞倒了。
(摩托车冲过来的时候本正在走路,所以"冲过来"用一般过去时,"正在走路"用过去进行时) 特别提示while引导的从句常用过去进行时,主句则用一般过去时。

英语主将从现的三种句型
英语主将从现的三种句型The present tense is a versatile tool in English that conveys an action happening now or a general truth. It's often used in three main forms: simple present, present continuous, and present perfect.In the simple present, we describe habits, routines, and universal facts. For example, "The sun rises in the east," or "She brushes her teeth every morning."The present continuous is used when we want to express an ongoing action that is happening right now. It's formed with the auxiliary verb "to be" in the present tense followed by the "-ing" form of the main verb, like "They are playing soccer in the park."Lastly, the present perfect is employed to talk about actions that started in the past and continue up to the present, or actions performed during a period of time that is not yet finished. It's constructed with "have/has" followed by the past participle of the verb, such as "We have lived in this city for five years." This tense is particularly useful for showing the effects of past actions on the present.。
