swimming和swim的区别

第三人称单数:swims

现在分词:swimming

过去分词:swum

swim是动词,只能做谓

swimming可看成动名词,即名词,可作主、be swimming作谓语,swimming还能做伴随状语

例如 he's thinking of something,swimming in the pool.

swimming还能做后置定语,修饰前面的名词

如bread is eaten by a fish swimming in the pool.

e.g. I usually swim a few laps as warm-up during practices.我一般都会在训练中先游几圈作为热身。

She swam the 400 metres medley ten seconds slower than she did in 1980.她400米混合泳的成绩比其1980年慢了10秒。

My hobbies are painting and swimming.我的兴趣是画画和游泳。

注:swim的现在进行时同样是swimming,不要把它和作为名词的swimming搞混了。

e.g. He is swimming right now.她现在在游泳。
