1. People sometimes wonder (HOW) you can learn how body languages works. (The "how" is implied by the next sentence which introduces possible options on HOW you could learn body language...read books..or observe people directly) 2. It is of course possible to read books on the subject but you also need to (take) time observing people’s movements. CORRECT!! 3. A railway station is a particulary good place (FOR) such observation, (The station is good FOR (the purpose of) observation. Just like a spoon is useful FOR eating!) 4. as here people can (be) seen openly expressing eagerness,..CORRECT!! BY THE WAY!! other corrections u didnt ask for...but...why not im feeling crazy.. 1.learn how body languages works....LEARN HOW BODY LANGUAGE WORKS (no "s") 2. sorrow, impatient and many other human emotions by means of movement...IMPATIENCE (not impatient)

Hi Maria Everything is perfect English except: 'a particulary good place (in) such observation' which should be: 'a particulary good place (for) such observation'

(if) should be (how), since the rest of the text is about how you can learn how body language works. (take) should be (spend). Take time would be to take your time, to not hurry, but I think spend as in to spend your time in a specific way (observing movements) would be better. (in) should be (for) because the wording when using is and good is "is good for [someone/something]". It is good for you. (Not "it is good in you"!) (be) is correct.
