WordPress分页页面的条件标签？

I am working with WordPress Conditional Tags and want something different that is not common. Currently I am using below codes on index.php of a WordPress Template that is juts covering 66% of my desire that I shared below.

<?php if(is_home() && !is_paged()):?>
<!-- Different Data Will Be Shown On First Page Only Like www.example.com -->
<?php else: ?>
<!-- Different Data Will Be Shown On All Pages Except First Only Like www.example.com/page/2/, www.example.com/page/3/, www.example.com/page/4/, www.example.com/page/5/ ....  -->
<?php endif; ?>

But I want to show different data on main page and also on www.example.com/page/2/ as something below...

<?php if(is_home() && !is_paged()):?>
<!-- Different Data Will Be Shown On First Page Only Like www.example.com -->
<?php elseif( conditional goes here ) ?>
<!-- Different Data Will Be Shown On Second Page Only Like www.example.com/page/2/ -->
<?php else: ?>
<!-- Different Data Will Be Shown On All Pages Except First And Second Only Like www.example.com/page/3/, www.example.com/page/4/, www.example.com/page/5/ ....  -->
<?php endif; ?>

So Is this possible and if yes then what code should be use instead of conditional goes here?

So basically you just want this

<?php if(is_home() && !is_paged()):?>
<!-- Different Data Will Be Shown On First Page Only Like www.example.com -->
<?php elseif( conditional goes here ) ?>
<!-- Different Data Will Be Shown On Second Page Only Like www.example.com/page/2/ -->
<?php elseif( conditional goes here ) ?>
<!-- Different Data Will Be Shown On Second Page Only Like www.example.com/page/3/ -->
<?php else: ?>
<!-- Different Data Will Be Shown On All Pages Except First Only Like www.example.com/page/4/, www.example.com/page/5/, www.example.com/page/6/ ....  -->
<?php endif; ?>

Is this what you meant?

EDIT:

To answer what you'd need to add in the conditional.

Well you'd have to add a check if it's a specific page with is_page(), but you'd need to have id's of that pages first. This is not a broad function that you can implement on any theme and will work because you are targeting your pages. The pages you create are specific.

Say you create a page that is called About us. That page will have some id assigned to it, which you can check by going on the pages menu in wp, and then hovering over pages link, and looking down on the url that pops up in the lower left side of your browser. It will have the format like:

www.example.com/theme/wp-admin/post.php?post=1234&action=edit

the 1234 is the id of that page. So you'd have to first check page id, then add that to conditional. But as I said, if you delete that page, and want another page in its place, you'd have to change the conditional accordingly. It won't automatically recognize what you want...
