[Grammar] Let your books opened.

[Son Ho]

Good morning teachers! Could you please check the five following sentences? I have changed the bold sentence into five different passive-voice ones. I was wondering whether I can use all of them.Thanks in advance.

Open your books.

1. Have your books opened.
2. Get your books opened.
3. Let your books opened.
4. Your books must be opened.
5. Your book should be opened.

 

[Son Ho]

#3 is incorrect. The others are OK, but 'open' would be more natural than 'opened'.

If I add be in front of opened, is it correct?
3)Let your books be opened.

I think "be opened" suggests the book is opened by someone else.

I prefer: have your books open.
