一般現(xiàn)在時含行為動詞

1、含行為動詞的 一般現(xiàn)在時只有主語在第三人稱單數(shù)時,用動詞的“三單形式”， 其他人稱用動詞原形表示。例如：I come from China. We come from China. They come from America. She/He/Tom comes from England. 動詞三單形式的變化規(guī)則： 1.（1）多數(shù)直接在動詞詞尾加_ play plays like likes ask- work- get- call-（2）以字母s, x, ch, sh或o結(jié)尾的動詞，在詞尾直接加_ watch- wish- do- go- （3）以“輔音字母加 - y”結(jié)尾的動詞，要先變_
