Answer 1

1/ visiting 句中已有follow这个谓语动词，所以用visiting这一非谓语形式，表伴随
2/ were watching 当while引导时间状语从句，它所在的从句用进行时，并且由got可知时态是过去
3/ amazing amazed amazing意为令人惊讶的；amazed意为感到惊讶的 make sb+adj意为使某人感到怎么样。填amazed作us的宾补
4/ landing getting see sb doing sth，用doing形式作sb的宾补，表示动作正在进行，翻译为这男孩看到了UFO着陆和一个外星人走出UFO的。（如果两个都填动词原型，则强调整个过程，亦可）
5/ were watching 由时间状语last night确定时态为过去式；又因为时间具体指明是8点到10点这一时间段，故用进行时
6/ was doing 时间状语从句，从句是when the teacher in当老师进来的时候，所以主句用进行时，并且是过去时
7/ closed keep sth +adj 使某物处于什么状态。翻译：请让窗户关着吧（处于关着的状态）
8/ was destroyed 被毁灭，用被动语态，并且是记叙过去的事情，用过去时
