Do you think she has a healthy lifestyle?has
He wants to fly the kite with his brother.to fly第一题为什么要改为 has 啊？第三人称单数一般现在时用does,be动词用is,动词之后加s,es或特殊形式；过去式时用did,be动词用was,动词之后加ed,d或特殊形式。这不是疑问句吗？不是要变回原形吗是疑问句，也是宾语从句Do you think （she has a healthy lifestyle）? 括号内为宾语。从句也是一个句子，里面也有三单。例如Do you know who has won Red Alert game?
