disappear when you are in space.,You will be weightless.,The gravity of the moon is,very light.,You will weigh less than on the earth.,3/44,The gravity on the moon is,1/6,as strong as it is on earth.This means that someone who weighs,150 lbs(磅),on Earth would weigh only,25 lbs,on the moon!You might think that this would make walking much easier,but it is actually quite difficult Later in

on the moon.(),3.Since the gravity has changed,their walk didnt need a lot of practice.(),F,F,F,13/44,Detailed reading:,Read Para 2 carefully and underline 3 sentences that show,the changes of the gravity,.,as he left,in space,on the moon),14/44,the way gravity changed,left the earth,in space,on the moon,It became very light.,The gravity became very strong.,The gravity disappeared.,15/44,T,he three ways in which gravity changed for Li Yanping and how his weight changed.,1.The pull of gravity became very strong she left the earths atmosphere.His weight is normal.,2.It disappeared when he was in space.He is weightless.,3.It was very light when he was on the moon.He weighs less than on earth.,16/44,Was their returning painful?What happened to the spaceship?,Yes.Fire broke out on the outside of the spaceship.Q&A,17/44,Last month I visited the moon with my friend.Before we left,I was told the force of _ would change three times on our journey.Then we took off.Gradually the weight _.When I was in space,it _.We _ weightlessly in the cabin and I _ _.When I was on the moon,I was surprised to find out even walking needs lots of practice _ _ gravity changed.The returning of the earth was very _.We were amazed to watch fire _ _ on the outside of the ship.,gravity,lessened,disappeared,floated,cheered up,now that,frightening,break out,Summary,18/44,If you visit the moon,what
