高一英语的2个问题（教材）
1.I can well remmember that there was a time that the song of the birds,moonlight and flowers could never have kept me spellbound.
为什么这里要用“have kept me spellbound”而非“keep me spellbound”？一定要用现在完成时么，为什么要用？
2.I didn't go downstairs until the window had to be shut.
为什么这里用“had to be shut”而非“was shut”？一定要用过去完成时么，为什么要用？
