Shoud in If-clauses

We can use "should" in "if-clauses" when we believe that the possibility of something happening is small.

If you should happen to see him before I do, can you tell him that I want to speak to him urgently? 

اگر آپکا ڈاکٹر کے پاس مجھ سے پہلے جانا ہوا تو کیا

آپ اُسے بتا سکتے ہیں کہ میں بات کرنا چاہتا ہوں؟

If there should be a problem, just give me a call and I'll sort it out.

اگر کوئی مسئلہ ہوا تو بس مجھے کال کر دینا-

If anyone should ask where I am, say I'm in a meeting.

اگر کسی نے میرا پوچھا کہ کہاں ہوں، تو کہنا کہ میٹنگ میں ہوں-

1) The shop is closed (adjective).

If a shop, public building etc is closed, it is not open and people cannot enter or use it. "Shut" is the synonym of closed, and "open" the opposite. First of all, we should know the difference between “close” and “closed.” As an adjective, both words have different meanings. 
The shop is closed. = It means the shop is not open.
The shop is close (to my house.) = It means the shop is not far.

2) The shop is open.

Open (adjective) means not closed, so that things, people, air etc can go in and out or be put in and out.

Opposite: closed, shut.
