一般现在时怎样运用
解题思路: 将用法系统化
解题过程:
1、 定义:
A)表示现阶段经常发生的、反复的发生的、习惯性的动作或存在的状态。如:He usually goes to school at 7:oo o’clock. The students often get up at 6:30 in the morning. B)表示主语具有的特征、性格、能力和客观真理。如: I’m 14 years old . Mike likes swimming.
2、标志词: often usually always sometimes every day/night/week on Sunday on weekends
3、结构:
A)当句子表状态说明主语是什么或怎么样时,其句型:主+BE动词(am, is, are)+表语,否定式是在BE动词后加not,一般疑问句是将BE动词提前到句首(即在主语之前) e.g. He is her father . He is not her father . Is he her father? Yes, he is . No, he isn't.
B) 当谓语由实义动词充当,主语不是第三人称单数时, 句子结构为:主语+动词原形+其它 否定式为:主语+don't+动词原形+其它 疑问句为:Do+主语+动词原形+其它? e.g. We speak Chinese. We don't speak Chinese.
Do you speak Chinese? Yes,we do. No, we don’t.
当主语是第三人称单数时: 句子结构为 主语+动词(词尾加s或es)+其它。 否定式为:主语+doesn't+动词原形+其它。 疑问句式:Does+主语+动词原形+它? He likes pandas. He doesn’t like pandas. Does he like pandas? Yes,hedoes. No, he doesn’t.
最终答案:略
