问几个英语问题!急!
1.He arrived at the airport,where he (was met) by his aunt.
2.The way the guests (were treated) in the hotel influenced their
evaluation of the service.
3.During the period of recent terrorist activities,people (were always being warned) not to touch any unattended bag.
4.It is (considered proper) to arrive several minutes early before a job interview.
5.In recent years many football clubs (have been run) as business to make a profit.
帮忙解释下为什么用括号里的词~~~谢谢啦!
是被动，但为什么用这时态~~~~？详解下嘛，Please!

Answer 1

1.括号后面by his aunt表明是meet的被动语态,所以用be met.前面是arrived,为了保持句子时态一致,be 要用was.
2.这里的意思是宾馆里客人被招待的方式会影响他们对宾馆服务的评价.所以是被动语态,GUESTS 是复数且后面inflenced是过去时态,所以用were treated.
3.首先这里还是被动,人们被警告,前面半句表示的是一段时间,所以这里应该是人们一直被这样警告着,所以需要用进行时态,表示一直.所以这里应该用were always being warned.
4.it is considered... it 做形式主语,这是固定句法,相当于people consider.不过这样说不地道,仅供参考理解
5.被动语态表示足球俱乐部被运行,注意前面时间状语,in recent years表示的是一段时间,用完成时态表示已完成并至今产生影响.所以是have been run
