1、第三人稱單數問題不規則變化：do- does have-has在一般現在時中，當主語是第三人稱單數時，謂語動詞要用第三人稱單數形式，即常在動詞原形后加-s或-es。但有些同學們對于哪些主語是第三人稱單數還不十分清楚，現歸納總結如下： 動詞原形變第三人稱單數的規則與發音規律同名詞單數變復數大致相同，請認真觀察。1、大多數動詞在詞尾加“S”如：stopstops s ; makemakes s readreads z ; playplays z2、以輔音字母加“y”結尾的，要先將“y”變為“i”，然后在加“es”讀iz 如：flyflies z； carrycarries z studystudi

2、es z; worryworries3、以“s, x, ch, sh”結尾的，在詞尾加“es”，發音為iz 如：teachteaches iz; watchwatches iz4、以“o”結尾的動詞，加“es”， 如：gogoes z dodoes z5.特殊的 have-has注：下面幾個動詞變為單數時，原詞的元音部分的發音發生了較大的變化，請注意記憶。 如：1、do du:does dz 2、say seisays sez以不發音字母“e”結尾的開音節詞，如果尾音是s，z時，加“s”后字母“e”發音，與所加“s”一起讀做iz。 如：closecloses izgo do play jump
