She could hardly sing a song怎么变成反义疑问句

一：--She could hardly sing a song.
变成反义疑问句：
She could hardly sing a song,could she?
分析：hardly表否定,由于前面是否定,所以后面用肯定
二：--I used to get up early.
变一般疑问句：
Did you use to get up early?
分析：一般疑问句一般用Do/Does/Did开头,例句中有used,所以是过去时 态,用Did,后面的话把原句改为一般现在时就行了.
三：--If you work hard.
变为祈使句：
Please work hard and .
祈使句多用Please开头,后面的话把主语如you,删去,后面的照抄即可.
