Answer 1

【答案】
（1）What；had
（2）hadn't
（3）I；haven't
（4）How；long
（5）when
【解析】（1）划线部分是句子的谓语，用What 提问，时态为过去完成时，故填 What had。
（2）否定句需要在助动词后面加 not，故填 hadn't。
（3）从 Have you ever been可知句子是现在完成时，否定句中主语 you 要变为第一人称 I，故填 I haven't。
（4）划线部分 since his tenth birthday 表示时间段，用 How long提问。
（5）At that time 意为“在那时”，引导时间状语从句，可以用 when 替换。
