一般现在时专项讲解及练习题一、概念：一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。用法可概括为：经常性或习惯性动作，常与表示频度的时间状语连用。如：often， always，sometimes, every , on Sunday等；I go to school on weekdays.现在时刻的状态、能力、性格、个性。如：I dont want so much. Ann Wang writes good English but does not speak well.普遍真理、客观事实等。如：The earth moves around the sun. Shanghai lies in the east of China.注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。例：Columbus proved that the earth is round.表示格言或警句中。如：Pride goes before a fall. 骄者必败。二、构成：一般现在时的构成主要有两种形式： （1）be型：句子的谓语动词只有be（am，is或are）： a肯定句中，只出现be，如： I am a student我是一名学生。 b否定句中，要在be后面加not，如： She isnt a teacher她不是教师。 c一般疑问句，要将be放在句子开头（注意句首字母大写），句尾用问号，答语用Yes，主语+be或No，主语+be+not如： Are you ready？你准备好了吗？ Yes，I am是的，我准备好了。 （No，Im not不，我没准备好。）试题演练：1). She is a beautiful girl with long black hair. (改为否定句和一般疑问句并作肯定否定回答)2). They are Chinese students. (同上)（2）实义动词型：句中的谓语动词为实义动词（也叫行为动词）： a肯定句中，只出现实义动词，如： I get up in the morning我早晨起床。 b否定句中，要在实义动词前面加do（does）not，do（does）作助动词，本身无意义，常与not缩写成dont（doesnt），如： I dont like vegetables我不喜欢蔬菜。 c一般疑问句，要在句子开头加助动词Do（does），句尾用问号，简略答语用Yes，主语+do（does）或No，主语+do（does）not如： Do you like oranges？你喜欢桔子吗？ Yes，I do是的，我喜欢。 （No，I dont不，我不喜欢。） 试题演练：1). Tom goes to school by bike every day. (改为否定句和一般疑问句并作肯定否定回答) 2). We like playing basketball on the playground after school every day. (同上)注：主语是任何一个单数名词、不可数名词或者是第三人称单数，谓语动词要进行必要的变化，变化规律是：(1) 在动词后加-s，-es： 如：read - reads，write - writes，say - says(2) 以s，x，ch，sh 结尾的词加-es： teach - teaches，wash - washes，guess - guesses(3) 以辅音字母+y结尾的词变y为i再加-es： try - tries，carry - carries(4) 特殊变化的词：A. be (是) - am, is, areI +am ; she/he/it/名词单数+is ; we/you/they/名词复数+are 如: Lucy is at home now. 露茜现在在家。B. have (有) - have, hasI/we/ you/they/名词复数+have ; she/he/it /名词单数+has如: We have six classes every day. 我们每天上六节课。She has math from Monday to Friday.(5) 助动词do/does，使用了助动词就木有人称和数的变化，都用动词原形表示He doesnt like tennis because he thinks its boring.(6) 情态动词 can, may, must, need, ought to 等后跟动词原形：We can see some pictures on the wall. 我们能看到墙上的画专题专练1：（一）单选：1.
