四、句型转换。
1. My birthday is on Oct. 1st.（对画线部分提问）
birthday?
2. Sarah has a cute kitten.（改为一般疑问句）
Sarah a cute kitten?
3. They can't walk because they are very young.（对画线部分提问）
walk?
4. The kitten is six days old.（对画线部分提问）
the kitten?
5. Is her birthday in June?（作否定回答）
, .

1. When is your
2. Does; have
3. Why can't they
4. How old is
5. No; it isn't

1. 画线部分Oct. 1st是具体日期，对时间提问要用特殊疑问词When，原句第一人称my要转换为第二人称your，将be动词is提前即可得到正确问句。
2. 原句是一般现在时，主语Sarah是第三人称单数，改为一般疑问句需要在句首加助动词Does，后面的实义动词has要变回原形have。
3. 画线部分是原因状语，对原因提问要用特殊疑问词Why，保留原句的情态否定词can't和主语they即可得到正确问句。
4. 画线部分six days old是年龄，询问年龄要用固定疑问词组How old，后接be动词is即可完成提问。
5. 以Is开头的一般疑问句，主语her birthday指代事物，否定回答的结构为No + 逗号 + 指代主语的it + 否定形式isn't。
