英语一般现在时动词用法全解英语中的动词时态非常重要,而一般现在时 (Simple Present Tense)是最基本的时态之一。
我们来全面解析一下英语一般现在时动词的用法。
一、动词的基本形式在一般现在时中,动词使用原形,即基本形式,不加任何变化。
例如:1. I study English every day. (我每天学习英语。
)2. They play football on weekends. (他们周末踢足球。
)3. She works in a hospital. (她在一家医院工作。
)二、第三人称单数形式在第三人称单数形式中,动词要加上-s 或 -es 结尾。
其中大部分动词只需加上 -s,而以下情况例外:1. 以辅音字母+ y 结尾的动词,在第三人称单数形式中,变为-ies。
例如:- study → studies (学习)- fly → flies (飞)2. 以 -s, -sh, -ch, -x, -o 结尾的动词,在第三人称单数形式中,变为 -es。
例如:- miss → misses (错过)- watch → w atches (观看)请注意以下动词特殊变化形式:1. have → has2. do → does3. go → goes4. can → can(无变化)5. want → wants例句:1. He reads a book every night. (他每晚读一本书。
)2. She teaches English at a school. (她在一所学校教英语。
)3. My mother cooks delicious meals. (我的妈妈做的饭菜很好吃。
)三、动词用于否定句和疑问句在否定句和疑问句中,需要使用助动词 do 或 does。
同时需要注意下列规则:1. 在否定句中,将 do not 或 does not 放在动词前面。
例如:- I do not study French. (我不学法语。
一般现在时主语单三人称时的动词变化①在一般现在时中,当主语为第三人称单数时,动词要用“s”型(即第三人称单数形式)。
②所谓动词“s”型的构成,可按名词变复数的规则来记,即:(1)在动词尾直接加s。
如:play—plays,want—wants,work—works,know—knows,help—helps,get—gets(2)以字母s、x、ch或o结尾的动词加-es;如:guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch—watches,catch—catches(3)以辅音字母+y结尾的动词,先变y为i,再加-es。
如:study—studies,carry—carries,fly—flies,worry—worries③④强调如何将主语是第三人称单数的肯定句变为否定和疑问句。
现举例说明:1)His mother works in a factory.His mother doesn’t work in a factory.Does his mother work in a factory?Mr Li teaches us English.Mr Li doesn’t teach us English.Does Mr Li teach you English?3)My brother studies maths well.My brother doesn't study maths well.Does your brother study maths well?其实三单的变化形式跟名词变复数是一样的。
好好学习哈O(∩_∩)Oaux.(助动词)1.be用作助动词时可与动词的现在分词连用,构成进行时态,也可与及物动词的过去分词连用,构成被动结构。
2.be可以和动词不定式连用,有以下几点意义:①表示计划或安排要发生的事或打算要做的事,不定式可用被动式,在was或were后用不定式的完成式可表示“本来打算…”;②表示“必须”“得”等,意思接近must, have to;③表示“应该”“宜于”等,意思接近should,有时用来征求对方的意见,不定式可用被动式;④表示“可以”“能”等,意思接近can, may,多用于被动结构;⑤表示“想要”等,意思接近want to, intend to;⑥表示注定要发生的情况,常用于过去式;⑦表示虚拟语气,用于与事实相反的条件句中。
