一般现在时的句式变化口诀
一般现在时的句式变化口诀：一般现在时，句式常变化。
首看人称后，是be还是动。
若是be动词，方式最简单。
be后加not，就是否定句。
置be于句首，便是一般问。
再加疑问词，则是特殊问。
人称后无be，应是实意动。
该句本无be，变化不用be。
若要变句式，只加助动词。
选择does/do，关键看人称。
单三用does，其余都用do。
要变否定句，人称后加助。
not紧随后，动词复原形。
前置助动词，动词亦复原。
句尾加问号，便是一般问。
只有问主语，词序不需变。
选对疑问词，去掉主语词，加上剩余词，肯定没问题。
无论be和动，只要变特问，定有划线词，相应疑问代。
划线包含动，what来提问，人称后加do，千万不能少。
一句现两do，功能不相同。
前是助动词，本身无意义。
后是实意动，代替原句动。
确定是否要，一译便可知。
问人用wh o，问地用where，问时用when，问物用what，,方式和程度，都用how问。
只是用whose，其后不丢名。
询问哪一个，which来引领。
若是问数量，可数how many,不可how much，二者不能混。
用法同whose，其后必加名。
注意有一点，原句人称我。
变成疑问句，都要改成你。
英形无差错，汉意也通顺。
二者相一致，变化才算对。
规律挺简单，是你不明白。
含be变特问，两加一减法，加疑问代词，句尾加问号，减疑问内容。
含动变特问，三加一减法，加疑问代词，紧跟助动词，句尾加问号，减疑问内容。
无论be和动，疑问代词后，词序都一般。

一般现在时的否定句形式
一般现在时的否定句形式（原创实用版）目录1.引言：一般现在时的否定句的重要性2.一般现在时的构成3.否定句的构成4.举例说明5.结论：总结一般现在时的否定句形式正文在英语语法中，一般现在时是一个非常基础的时态，它用来描述经常或者习惯性的动作、状态或者真理。
当我们需要表达一般现在时的否定意义时，我们需要构建否定句。
本文将详细讲解一般现在时的否定句形式。
首先，我们需要了解一般现在时的构成。
一般现在时由两部分组成：主语和谓语。
主语是句子的主体，谓语则用来表示主语的状态或者动作。
例如：“I study English every day.”（我每天学习英语。
）在这个例子中，“I”是主语，“study”是谓语。
接下来，我们来看一下否定句的构成。
在英语中，否定句通常通过在谓语动词前添加助动词“do”的否定形式“do not”（缩写为“don"t”）来构成。
因此，在一般现在时的否定句中，我们需要在主语和谓语之间添加“do not”。
以刚才的例子为例，将其改为否定句：“I do not study English every day.”（我每天不学习英语。
）现在，让我们通过一些例子来更好地理解一般现在时的否定句。
例如：- 一般现在时肯定句：She watches TV in the evening.（她晚上看电视。
）否定句：She does not watch TV in the evening.（她晚上不看电视。
）- 一般现在时肯定句：He goes to the park on weekends.（他周末去公园。
）否定句：He does not go to the park on weekends.（他周末不去公园。
）通过这些例子，我们可以看到在一般现在时的否定句中，助动词“do”的否定形式“do not”起到了关键作用。
总之，当我们需要表达一般现在时的否定意义时，我们需要在主语和谓语之间添加助动词“do”的否定形式“do not”。
英语四大时态变化规则
英语四大时态变化规则英语语法中有四种主要的时态，它们包括：一般现在时（Simple Present）、一般过去时（Simple Past）、一般将来时（Simple Future）、和现在完成时（Present Perfect）。
下面是每种时态的变化规则：1. 一般现在时（Simple Present Tense）：-陈述句：主语+ 动词原形（第三人称单数主语需要在动词后面加-s）。
例子：He works in an office.-否定句：主语+ 助动词"do" / "does" + not + 动词原形。
例子：They do not like coffee.-疑问句：助动词"do" / "does" + 主语+ 动词原形。
例子：Do you play the guitar?2. 一般过去时（Simple Past Tense）：-陈述句：主语+ 动词过去式形式。
例子：She visited Paris last year.-否定句：主语+ 助动词"did" + not + 动词原形。
例子：I did not finish my homework.-疑问句：助动词"did" + 主语+ 动词原形。
例子：Did they arrive on time?3. 一般将来时（Simple Future Tense）：-陈述句：主语+ 将来时标志词"will" + 动词原形。
例子：I will go to the store tomorrow.-否定句：主语+ 将来时标志词"will" + not + 动词原形。
例子：She will not attend the meeting.-疑问句：将来时标志词"will" + 主语+ 动词原形。
否定句的变化规则
否定句的变化规则一、含有be动词（am/is/are/was/were）的句子1. 规则- 直接在be动词后加not。
- 例如：- 肯定句：I am a student.- 否定句：I am not a student.- 肯定句：He is at home.- 否定句：He is not (isn't) at home.- 肯定句：They are happy.- 否定句：They are not (aren't) happy.- 肯定句：She was in the park yesterday.- 否定句：She was not (wasn't) in the park yesterday. - 肯定句：We were good friends last year.- 否定句：We were not (weren't) good friends last year.2. 注意事项- 在一般现在时中，am与第一人称I连用；is与第三人称单数（he/she/it 等）连用；are与第二人称you及复数（we/they等）连用。
- 在一般过去时中，was与第一人称I和第三人称单数（he/she/it等）连用；were与第二人称you及复数（we/they等）连用。
二、含有情态动词（can/could/may/might/must/should等）的句子1. 规则- 在情态动词后加not。
- 例如：- 肯定句：He can swim.- 否定句：He can not (can't) swim.- 肯定句：You could play football when you were young.- 否定句：You could not (couldn't) play football when you were young.- 肯定句：She may come tomorrow.- 否定句：She may not come tomorrow.- 肯定句：We must go to school on time.- 否定句：We must not (mustn't) be late for school.- 肯定句：You should study hard.- 否定句：You should not (shouldn't) waste your time.2. 注意事项- mustn't表示“禁止，不许”，有较强的命令语气。

（1）如果主语是第三人称单数时，要在实义动词前加doesn't,后面的动词用原形。
例1 He eats an apple.否定句He doesn't eat an apple.例2 Jim does his homework.否定句Jim doesn't do his homework.例3 Marry goes to school.否定句Marry doesn't go to school.(2) 如果主语不是第三人称单数时，只需在实义动词前加don't.例1 I teach English.否定句I don't teach English.例2 They go to school.否定句They don't go to school.例3 We sing a song.否定句We don't sing a song.(c) 含有情态动词的句子,变否定句时, 只需在情态动词后加not.例1 I can dance.否定句I can not dance.或I can't dance.例2 They can speak English.否定句 They can not speak English.或They can't speak English.例3 He must go home.否定句He must not go home.或He mustn't go home.例4 He must be on the playground.He can not be on the playground.析：当must be用来表示推测，有“一定”的含义时，否定式要用can not.例5 You must say something at the mecting.You needn’t say anything at the mecting.析：当“must+行为动词”用来表示“必须”的含义时，其否定式可用needn’t 或mustn't表示“不需要”，“不必”，语气委婉，must not表示“禁止”，“千万别”语气生硬。
