Am I a good stude nt? Are you a good stude nt?（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.iAre 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 helike 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 frie nds?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: clea nclea ns2) have4) go6) make8) draw10) play1) watch3) cook5) fly 7) swim9) ride二. 用动词的正确形式填空2.
