2、0; washes  brushes  pushes  flashes    teaches  watches  matches3. 單詞結尾y，千萬別亂猜，元加y就不改，直接加s，輔音加y，改y為i加es:stay   pay  play  buy  say  enjoy  destroy  display  spray  slaystudy-studies  carry carries

3、0;  marrymarries  worryworries hurryhurries fly-flies  try-tries  drydries crycries bury-buries4. 記住特殊的兩個單詞go和do后面加es：goes   does5. 記住最為特別的be的三單是is; have的三單是has.六單詞三單變化練習，填充下列表格：詞尾只加s詞尾要加es不改y直接加s改y為i加eso后加es1    2   3
