8、？ Yes， I do. 是的，我是。 Does he play baseball？ 他打棒球吗？ No， he doesnt 不，他不打。 Where does her father work？ 她父亲在哪儿工作？ He works in an iron factory. 他在一家铁厂工作。 注意 用疑问词在句首组成的特殊疑问句，不需要回答 Yes(No)。由于在问句中出现 Do(Does)，所以动词保持原形。但回答时，动词须视主语而决定是否加-s 等。 从肯定句改为疑问句，由下列的步骤去思考： 先判断主语是第三人称单数或是其他情形。如果主语不是第三人称单数，就使用 Do，然后在句尾加“？”
