一般现在时与现在进行时讲解及练习一般现在时一、定义与讲解：一般现在时表示经常或习惯性的动作或一般性事实。，也可表示现在的状态或主语具备的性格和能力。通常与副词every day（每天），always（总是）,usually（通常）,often（经常）sometimes（有时）,等时间状语连用。例：（1）表示事物或人物的特征、状态。The sky is blue.天空是蓝色的。Marys father is an English teacher. 玛丽的爸爸是一名英语老师。 （2）表示经常性或习惯性的动作。I get up at six every day.我每天六点起床。She plays sports every day. 她每天都做运动。 （3）表示客观现实。The table has four legs.桌子有四条腿。There are 50 students in my class. 我们班有50个学生。（4）表示客观真理，科学原理，自然现象，等客观事实或格言谚语等。 The sun rises in the east every day.太阳每天从东方升起。The earth goes around the sun.地球绕着太阳转。（5）表示平日的喜好。I like bananas. We dont like vegetables.He likes ice cream. She doesnt like strawberries.二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。 动词三单形式的变化规则：1.（1）多数直接在动词词尾加-s. play plays like likes ask-asks work-works get-gets call-calls（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es. watch-watches wish-wishes do-does go-goes （3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es. try-tries study-studies cry-cries fly-flies2.不规则变化：be- is have-has三、一般现在时的句子转换：（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等)提到主语的前面，（口诀：一调二变三问号）; （2）变否定句：在be动词或情态动词后面直接加not变成否定句. (be后not莫忘记)例：陈述句：She is my sister.疑问句 Is she your sister? Yes, I am./ No, Im not.否定句 She is not my sister.陈述句：I can play soccer.疑问句 Can you play soccer? Yes,Ican./ No, I cant.否定句 I can not /cant play soccer. 注意：对一般疑问句的回答：一般用什么问就用什么来回答。但以下例外：Is this a pencil? Yes , it is./ No, it isnt.Is that your backpack? Yes , it is./ No, it isnt.Are these your parents? Yes, theyre./ No, they arent.Are those Jims brothers? Yes, theyre./ No, they arent.（3）当句子中没有be动词，也没有情态动词时，变一般疑问句时，在主语前加助动词do (I, we, you,以及复数), does（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dont, doesnt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. I是个字母。一、按照要求改写句子 1This is my pencil ? (变一般疑问句) your pencil ? 2. These red socks are Kates . (变一般疑问句) socks Kates ? 3. Mary does not have any books . (变肯定句) some books . 4.
