一般现在时含行为动词.doc

含行为动词的 一般现在时只有主语在第三人称单数时,用动词的“三单形式”， 其他人称用动词原形表示。例如：I come from China. We come from China. They come from America. She/He/Tom comes from England. 动词三单形式的变化规则： 1.（1）多数直接在动词词尾加_ play plays like likes ask- work- get- call-（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加_ watch- wish- do- go- （3）以“辅音字母加 - y”结尾的动词，要先变_ try- study- cry- fly-2.不规则变化：be- have-三、一般现在时的句子转换：（1，变一般疑问句时，在主语前加助动词_ (I, we, you,以及复数),_-（第三人称单数she,he,it等）变成问句；（4）变否定句时，在主语后谓语动词前加助动词_变成否定句，切记：助动词后的动词则还原成动词原形。例：陈述句：We get up（起床） at 7:00 every morning.疑问句Do you get up at 7:00 every morning?否定句We dont get up at 7:00 every morning.陈述句：She has a brother.疑问句 Does she have a brother? 否定句 She doesnt have a brother. 在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、人称代词he, she, it是第三人称单数。如： He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei likes salsd . 韩梅喜欢萨拉。 Beijing is in China. 北京在中国。 Uncle Wang often plays volleyball. 王叔叔经常打排球。 三、单数可数名词或this / that / the+单数可数名词作主语时，是第三人称单数。如： This book is yours. 这本书是你的。 That car is red. The cat is Lucys. 这只猫是露茜的。 四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。Everyone is here. 大家到齐了。 There is a watch on the table. 桌上有块手表。 This is a pen. 这是一支钢笔。That is an eraser.五、不可数名词作主语时为第三人称单数。如： The milk（牛奶） is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。 I is a letter. . 一般现在时用法专练:一、 写出下列动词的第三人称单数形式。 have like drink _ go _ stay _ study_ _ teach_ play_make _ look _ _have_ come_ watch_ plant_ fly _ _ do_ 二、用括号内动词的适当形式填空。1.
