一般現在時主語單三人稱時的動詞變化
①在一般現在時中，當主語為第三人稱單數時，動詞要用“s”型（即第三人稱單數形式）。
②所謂動詞“s”型的構成，可按名詞變復數的規則來記，
i）在動詞尾直接加 s。如：play—plays，want—wants，work—works，know—knows，help—helps，get—gets
ii）以字母s、x、ch或o結尾的動詞加-es；如：guess—guesses，fix—fixes，teach—teaches，brush—brushes，go—goes，do—does，watch—watches，catch—catches
iii）以輔音字母＋y結尾的動詞，先變y為i，再加-es。如：study—studies，carry—carries，fly—flies，worry—worries
