Are you a good student?(I am 是特殊的，通常用Are you?进行提问)He is a tall boy. Is he a tall boy?They are cute flowers. Are they cute flowers?I can run very fast. Can you run very fast? (句子中出现I，都要改成you)She will go to the park. Will she go to the park?3. 若句子中没有出现以上几个单词，就考虑用do does来进行提问，放在句子的最前面。a.当句子的主语不是单数第三人称时，用do来提问，后面句子照抄，句子中的I 变成youI like to eat apples. Do you like to eat apples?They have five cats? Do they have five cats?句子中主语I they 都不是单数第三人称，所以用do提问，放在句子最前面，有I 的地方改成you, 其他不变。b.当句子的主语是单数第三人称时，用does来提问，后面句子照抄，但是注意动词必须改为原形。He likes to eat pizza.Does he like to eat pizza?The bird flies in the sky.Does the bird fly in the sky?His daddy plays balls with his friends.Does his daddy play balls with his friends?句子中主语He The bird His daddy 都是单数第三人称，所以用does提问，放在句子最前面，动词必须改为原形。一、写出下列动词的第三人称单数形式。(讨论第三人称单数形式的变化规则)Model: clean cleans1) watch _ 2) have _ 3) cook_ 4) go _ 5) fly _ 6) make _ 7) swim_ 8) draw_9）ride_ 10) play_二用动词的正确形式填空。1.We often_(play) in the playground.2.
