【小题1】His father watched a talk show last night. （对画线部分提问）
What; did; do Yes, did his father stayed last night?
【小题2】Did you play the piano this morning?（作肯定回答）

【小题3】 Gina always stays at home on weekends.（用last weekend作状语改写句子）
Gina 　 at home last weekend.
【小题4】My mother watches TV every day. (用now 作状语改写句子)
My mother 　 　 TV now.
【小题5】 Mary is very sad because she doesn’t do well in her English.（对画线部分提问)
　 　 Mary very sad ?

解析：【小题1】对做某事提问用疑问词what，后跟一般疑问句，本题为过去时，用助动词did构成一般疑问句，后跟动词原形do，故本题空格处填What; did; do。 【小题2】肯定回答的结构为yes，人称加引导词did，故本题空格处填Yes, did。 【小题3】用上个周末改写为过去时，谓语动词改为stayed。 【小题4】用now改为现在进行时，结构为be+doing，本题的主语为单数第三人称，故本题空格处填is; watching。【小题5】对于原因提问的用疑问词why，后跟一般疑问句，be动词is提前，故本题空格处填Why; is。
