在英语中，描述某件事情的时候，我们要先确定这件事情发生的时间，然后才能知道用什么时态。如果是正在进行的动作，需要用到进行时态，不过，有些词是没有进行时的，是哪些词呢?
一、不用进行时的动词有哪些?
一般情况下，不用进行时态的动词包括事实状态的动词、心理状态动词、瞬间动词和系动词。
1、事实状态的动词
事实状态的动词，也叫做状态动词，表示主语的状态或属性，不表示动作的进行，常用于表达存在、持有、感觉等状态。常见的状态动词有：be(am, is, are, was, were, been),seem(seems, seemed, seeming),feel(feels, felt, feeling),appear(appears, appeared, appearing),have(has, had, having),belong(belongs, belonged, belonging),sound(sounds, sounded, sounding),remain(remains, remained, remaining),look(looks, looked, looking),stay(stays, stayed, staying),taste(tastes, tasted, tasting),smell(smells, smelled, smelling),sound(sounds, sounded, sounding),become(becomes, became, becoming)需要注意的是，有些动词既可以表示状态也可以表示动作，如have、see、think等，具体使用需要根据上下文来判断。
例句：
I have two sisters.我有两个姐姐。
The girl in blue shirts is my sister.穿蓝色衬衫的女孩是我的姐姐。
2、心理状态的动词
心理状态的动词指的是表达主语的心理感受或思维活动的动词，常见的心理状态动词包括：think(thinks, thought,),believe(believes, believed,),know(knows, knew, known),remember(remembers, remembered,),forget(forgets, forgot, forgotten),understand(understands, understood),hope(hopes, hoped),doubt(doubts, doubted),imagine(imagines, imagined),suppose(supposes, supposed)
例句：

She believes that honesty is the best policy.她相信诚实乃上策。
3、瞬间动词
瞬间动词是指动作瞬间发生，持续时间非常短暂的动词。常见的瞬间动词包括：blink(眨眼),sneeze(打喷嚏),cough(咳嗽),hiccup(打嗝),laugh(笑),smile(微笑),clap(鼓掌
例句：
She blinked her eyes and looked away.她眨了眨眼睛，扭过头去。
He sneezed twice before reaching for a tissue.他打了两个喷嚏后，伸手去拿纸巾。
4、系动词
系动词是一类用来连接主语和表语的动词，使其构成完整的句子，表示主语的状态、性质、特征或身份的词语。常见的系动词包括：be(am, is, are, was, were, been, being),become(becomes, became, becoming),seem(seems, seemed, seeming),appear(appears, appeared, appearing),feel(feels, felt, feeling),look(looks, looked, looking),smell(smells, smelled/smelt, smelling),sound(sounds, sounded, sounding),taste(tastes, tasted, tasting)
例句：He is a doctor.他是一名医生。
She became interested in learning Chinese.她对学习中文产生了兴趣。
二、进行时的动词形式及变化规则
进行时是一种表示动作正在进行的时态。英语进行时是由“be”动词与动词的现在分词“-ing”构成。进行时的变化规则如下：
1、一般现在进行时：
构成：主语 + am/is/are + 现在分词
例句：I am studying English now.我正在学英语。
变化：be 动词根据主语的人称和数目变化，现在分词不变。
2、一般过去进行时：
构成：主语 + was/were + 现在分词
例句：I was watching TV when he called.他打电话的时候，我正在看电视。
变化：was/were根据主语的人称和数目变化，现在分词不变。
3、现在完成进行时：
构成：主语 + have/has been + 现在分词
例句：He has been working for 10 hours.他已经工作了10个小时了。
变化：have/has和been根据主语的人称和数目变化，现在分词不变。
4、过去完成进行时：
构成：主语 + had been + 现在分词
例句：She had been studying English for 5 years before she moved to China.她在搬到中国之前已经学习英语5年了。
变化：had和been不变，现在分词不变。
5、将来进行时：
构成：主语 + will be + 现在分词
例句：I will be waiting for you at the airport tomorrow.明天我会在机场等你。
变化：will/be和现在分词不变。
