How to insert a post content in to a page

Hello i need to get post content in to a page. in my site there are many pages and posts.should i add a post content in to a page’s spesific position. here is my example to clarify what i am talkin’about to:

an aducational page: mysamplesite.com/cts.html (in page.php)
Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) is a median entrapment neuropathy, that causes paresthesia, pain, numbness, and other symptoms in the distribution of the median nerve due to its compression at the wrist in the carpal tunnel.
and after this sentence i want to add an another posts content in here
mysamplesite.com/cps.html (in singlepost.php)
Cheiralgia paresthetica is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve.

so i need a shortcode plugin or stg like that to do it? or any idea?
thank you
