7.The "Thousand hand Guanyin"has been regarded by many people as the best performance at CCTV's Spring Festival Evening.
请问为什么不用被动形式?
第7题，我的疑问是为什么要加has，能用is regarded吗？

1.此句在书面上是：The meeting lasted (for) two hours.但是口语中的for经常会被省略.
所以last在此时是不及物动词,而不及物动词是没有被动语态的.
2.had built是过去完成时.而过去完成时是表示一个动作发生在另一个过去的动作/过去的时刻之前,即“过去的过去”.但是此题没有另外一个可以作为参照的过去动作/时刻.
如：They had built the house before it rained last week.
3.has been是指“截止到现在,它还在这儿”,这就和上下文的句意矛盾了.
所以用一般过去时表示过去发生的动作,和后句的now相对应.
4.change表示“变成”时也可作不及物动词,所以可以不必使用被动语态.
如果该句上下文强调了“被...所改变”如by sb时,则才必须使用被动语态.
5.该表语尚未发生,当然最好用不定式来表示.
而动词原形become不能用在此处,因为前面已经有了is做谓语；
也不能用动名词becoming,因为动名词短语表示经常发生的动作,而不定式才可以表示尚未发生的行为.
6.此题应该是答案错误,而楼主你自己的答案才是正确的,除非还有具体的上下文没有被楼主打完.
7.其实用is regarded也不能说绝对不可以,关键是看说话人的当时的具体意图.
