Answer 1

You can try it.

     <?php the_excerpt(); ?> 

or

    <?php the_excerpt(80); ?>

* 80 is a word Limit.

Answer 2

Add code in your function.php

add_action( 'init', 'my_add_excerpts_to_pages' );
function my_add_excerpts_to_pages() {
     add_post_type_support( 'page', 'excerpt' );
}

select 'excerpt' option in screenoption on page header. and add page excerpt content.

Answer 3

In WordPress the excerpt is a feature for posts, pages have the post_excerpt property but it is only because they share the same database fields as the posts. If you want to enable excerpt area for your pages put the following code in functions.php.

add_action( 'init', 'add_pages_excerpts' );
function add_pages_excerpts() {
    add_post_type_support( 'page', 'excerpt' );
}

Now there should be 'Excerpt' area in 'Admin->New Page' ( if not, open the screen options at the right top corner and click on 'Excerpt' checkbox ).
