一般现在时是英语中应用最广泛的时态之一,是初中英语语法重点。它表示1)经常性、习惯性的动作或存在的状态。e.g. I go to school on foot. He is very busy now. 2)表示主语的特征、性格、能力、爱好等。e.g. He can swim. I work hard. I like watching TV. 3)表示客观真理 e.g. There are seven days in a week. The moon moves round the earth.
其结构按正常语序,即主语+谓语+其它,有时为了起强调作用,时间状语也可提前.
其句式变化可分为两种情况 1)表示动作, 一般人称作主语的,变否定句须在动词前加助动词don变一般疑问句须在句首加助动词do。 E.g. They have lunch at 12:00. They dont have lunch at 12:00. Do they have lunch at 12:00? 2)单三人称做主语的,变否定句须在动词前加助动词doesn变一般疑问句须在句首加助动词does。
E.g. Jenny speaks English very well.
Jenny doesnt speak English very well.
Does Jenny speak English very well?
含有be动词的要在be上做变化.
E.g. Danny is a good student.
Danny isnt a good student.
Is Danny a good student?
其时间状语为often、 usually、 always、 sometimes等频率副词,on Saturdays、 in the morning(afternoon evening) 、every day 等。
学生常见错误如下:
一、be动词与行为动词同时出现在句子中
例:We are plant (plant) the trees in spring.
答案:plant
解析:学生往往会用汉语的思维方式去翻译,就成了我们是在春天植树。这是学习英语最忌讳的,要看语法是不是正确,在英语中,be是表状态,do是表动作,两种动词不能同时出现在句子中,可记住如下口诀:英汉语言有差异,be 、do不能放一起,仔细琢磨细分析,语法千万要牢记。

6 Who_____(想要 )to go swimming?
7 ______she_____(do) the housework every day?
8 Jenny and Danny usually______(play) games in the afternoon .
答案:1 comes 2 Does know 3 is away from 4 doesnt look
二、单三人称形式易出错
例:1 He plaies (play) football very well.
2 Danny gos (go) to school at 7:10.
答案:1 plays 2 goes
解析:1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es;2与名词变复数不同,变单三人称形式以o结尾的词要加es.
三、在句式变换时易出错
例:1 Does Jenny has (has) a good friend?
2 Brian doesnt lives (not live) in China.
答案:1 Does have 2 doesnt live
解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:见助动,用原形。此口诀也可推广用于一般过去时态中。e.g. He didnt go home yesterday.
四、对do的理解易出错
例:We dont (not do) our homework in the afternoon.
答案:dont do
解析:do是一个比较难理解的词,它有三个含义: a)是所有行为动词的总称;b)是助动词,无实义;c)是一个具体的行为动词做,干。此句中给出的do指做,干,not指把此句变为否定句,故须在do前加助动词dont。
五、对主语的数判断有误
例: Li Ming with me are (be) in Beijing.
答案: is
解析:表面一看是我和李明两个人在北京,但with在此做伴随状语,不能做主语,故用is.
另外,宾语从句中,从句部分若是表示客观真理,不管主句是何时态,从句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般现在时。
