题一的closed表示的是一种状态,意思是门已经关了两个钟,而close是短暂性动作(瞬间完成的动作),不是持续性,而现在完成时的动词应该是持续性,所以此处closed是形容词.
题二open是形容词.表示一种状态,具有持续性.

have been 后面加持续性动词（如eat,read,write etc.）的ing形式构成现在完成进行时.也可以加形容词（包括动词的过去分词形式如closed）构成现在完成时.

1）因为has been closed 是现在完成时，close是瞬间动词，所以这里的是形容词
原句是过去式
2）has been open（open是形容词）

1.The shop closed two hours ago. (closed动词的过去式）
2. The shop has been closed for two hours . （closed是过去分词做形容词；be是句子里的谓语动词，用了现在完成时）
open可以做动词，也可以做形容词：

现在完成时态 由have + 动词过去分词构成， 但是该动词得是延续性动词，不能是非延续性动词。

动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。
一.延续性动词表示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词可以与表示时间段的状语连用。


表示时间段的短语有:for+一段时间,for 2 years; for a long time
since从句,since he came here; since+时间点名词,since last year, since 5 days ago; 等。
例:He has lived here for 6 years.
You can keep the book for 5 days.
I stayed there for 2 weeks last year.




二.非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束。 如:open, die, close, begin, finish, come, go, move, borrow, lend, buy等。


非延续性动词在肯定句中与表示时间点的状语连用，如：two years ago; at 5 o'clock;


例:He died 5 years ago.

延续性动词和非延续性东西的转换
leave --- be away, borrow --- keep, buy --- have, die --- be dead,


finish --- be over, join --- be in+组织机构, be a member of+组织机构,


fall ill --- be ill, catch a cold --- have a cold, come here --- be here,


go there --- be there, come back --- be back, fall asleep --- be asleep,


get to/ arrive/reach --- be (in), leave --- be away from, get to know --- know,


go (get) out →be out， put on→ wear； catch a cold →have a cold等。
