Jim and Tom (run) there.,will swim,were,played,are watching,does,swim,do,are running,过去式之歌过去式构成有方法，一般词尾加ed。如果词尾有个e，直接加d就可以。辅音字母y在尾，变y为i加ed。“一辅重闭”作尾巴，双写之后加ed。标准过去式加ed，少量不规则分别记。am和is对was，are要变were没问题。have和has用had，do和does变did。,一般现在时用法一般现在时，everyday, usually, often, sometimes.第一、二人称和复数，动词原形不变换。除了I, you，复数外，动词后加s(es)别忘怀。要变一般疑问句，be动词提前很容易。若是没有be动词，Do和Does开头要注意。否定句，很简单，not在be动词后面站。若是没有be动词，do, does加not要牢记。请把这些规律记，一般现在时没问题。,谢谢观看,请指导,
