一般现在时是英语中应用最广泛的时态之一,是中考复习的重点。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’t;变一般疑问句须在句首加助动词do。 E.g. They have lunch at 12:00. They don’t 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’t;变一般疑问句须在句首加助动词does。E.g. Jenny speaks English very well. Jenny doesn’t 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 isn’t 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。 做题时常见错误如下: 一、be动词与行为动词同时出现在句子中 例:We are plant 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。” 专项练习: 一、 单选 1 Jenny ____ in an office. Her parents ____in a hospital. A work works B works work C work are working D is working work 2 One of the boys_____ a black hat. A have B there is C there are D has 3 We will go shopping if it____ tomorrow. A don't rain B didn't rain C doesn't rain D isn't rain 4 He said the sun ____in the east and ____in the west. A rose; set B rises; sets C rises, set D rise; sets 5 Wang Mei ____ music and often ____ to music. A like; listen B likes; listens C like; are listening D liking ; listen 6 Jenny____ English every evening. A has study B studies C study D studied 答案:1 B 2D 3C 4B 5B 6B 二、填空 1 I can take Li Ming there when he _____ ( come) to visit. 2 _____your sister_____(know)English? 3 Her home____ _____ ______(远离 )her school. 4 The pot_____(not look) like yours very much. 5 Where _____you____(have)lunch every day? 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 doesn't look 5 do have 6 wants 7 does do 8 play 二、单三人称形式易出错 例:1 He plaies football very well. 2 Danny gos 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 a good friend? 2 Brian doesn’t lives in China. 答案:1 Does have 2 doesn’t 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 didn't go home yesterday. 四、对do的理解易出错 例:We don’t our homework in the afternoon. 答案:don’t 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”,not指把此句变为否定句,故须在do前加助动词don’t。 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。
