一般现在时的几个口诀

一般现在时的几个口诀1. 一般现在时的标志口诀： 总是、经常、常常，有时、每一、没标志，星期 和 周末。口诀解释：这个口诀是一般现在时的时间状语标志口诀，遇到口诀里的单词（always/ often/ usually , sometimes/ every day./. She comes early .这句没有时间的标志 ，on Sundays/ at the weekends ），我们记得用一般现在时。2.一般现在时的动词口诀： 不是三单用原形，三单s、 es随后行。疑问、否定来光顾，三单之前加does ，不是三单就加个do 。Does 、Do 加在前，动词形式要还原。口诀解释：有了上面1的标志口诀，我们很容易判断一个句子是不是一般现在时。在一般现在时中，如果动词是BE动词，则相对简单。如果动词是实意动词，那么这个问题就成了一个难点。这个口诀降低了这个问题的难度。解释如下：在一般现在时中，当主语不是第三人称单数时动词用原形，是三单动词要加does。在疑问、否定句中，主语是三单的话，要在前面加助动词does；主语不是三单，前面加的助动词是do而无论前面加的助动词是does 还是do，其他的动词都要用原形。一、写出下列动词的第三人称单数Talk_ forget_hope_stop_perform _ play_say_buy_worry_fly_study_like_make_take_ love_ _recite_become _come_ _drive_ shine_ leave_ wake_ _ ride_ _ write_ _hike_ give_ see_ swim_ stop_ shop_ plan_ get_ _ sit_ let_cut_ run_ _ forget_ begin_ wash_ watch_finish_ teach_ fish_ reach _ go _do_二、用括号内动词的适当形式填空。1.
