How did a Space Rocket take off again from the surface of Moon?

I have seen many times in movies and other documentaries that when a space shuttle gets out of our atmosphere its propellers get detached and after flying for some time, it lands somewhere safely (Consider Moon). Now the question that has been troubling me is that if the rocket has no propulsion system to take off from the surface of moon then how does the rocket escape the Surface of Moon and how does it come back to Earth?  
(btw my first language is not English, so sorry if I said anything wrong)

The short answer is: the lunar lander also has a little rocket in it.

Almost every space rocket is a multistage rocket. This is not one rocket, but lots of rockets connected together. To take off, you use a big rocket, along with booster rockets on the side. After the big rockets and boosters have used all their fuel, they are detached, and fall back to Earth. This makes the rocket lighter, and it can now be pushed by a smaller (and lighter) rocket. You can do repeat this, and detach a medium rocket, and then use a small rocket. And then a smaller rocket, and so on. This helps make the rocket go fast enough to orbit Earth, or escape Earth and go to the Moon, or another planet.

No Space Shuttle went to the Moon, but after a Space Shuttle loses its booster rockets, it still has little rockets at the back. It uses these to manoeuvre in orbit, and to return to Earth.

In the Apollo missions, the lunar lander also had a little rocket in it The two big rocket stages were detached when the rocket launched. The last medium rocket stage was used to get the lunar lander close to the Moon. The lunar lander then used its own little rocket to land on the Moon, and take off again. It only needs a very small rocket because the Moon's gravity is much less than the Earth's, and it lacks an atmosphere. Then it attached again to the medium rocket, which brought it back home to Earth. The lunar lander didn't need to carry this medium rocket down to the Moon and back. This also helped the lunar lander to only need a smaller rocket.
