1．What's a spacewalk？Any time an astronaut gets out of a spacecraft while in space，it is called a spacewalk.Astronauts go on spacewalks for many reasons.For example，experiments can be placed on the outside of a spacecraft.This lets scientists learn how being in space affects different things.By going on spacewalks，astronauts can also fix certain things instead of bringing them back to the earth to fix.
When astronauts go on spacewalks，they wear spacesuits to keep themselves safe.Inside spacesuits，astronauts have the oxygen they need to breathe and the water they need to drink.To keep the astronauts and the spacecraft safe，the astronauts must leave and go back to the spacecraft through a special door.When on a spacewalk，astronauts use safety tethers to stay close to their spacecraft，which connect the spacewalkers with the spacecraft.They keep astronauts from floating away into space.Another way astronauts stay safe during spacewalks is by wearing a SAFER.SAFER is worn like a backpack.It helps an astronaut move around in space.
How do astronauts train for spacewalks？One way is by going for a swim.Floating in space is a lot like floating in water.Astronauts practice spacewalks underwater in a huge special swimming pool.For every one hour they will spend on a spacewalk，astronauts need to train seven hours in the pool.Another way astronauts practice for a spacewalk is by using virtual reality （虛擬視鏡）.It looks and feels just like a spacewalk.
Today，only three countries have finished spacewalks independently.They are Russia，the United States and China.The first person to go on a spacewalk in the world was Alexei Leonov from Russia.Zhai Zhigang is the first Chinese astronaut to go on a spacewalk.The world record of spacewalks is held by Russian astronaut Anatoly Solovyev.He has been on 16 spacewalks and spent more than 82 hours outside in space.

A．Fix different objects.

C．Carry out an experiment.
D．Study how things changes in space.
（2）What does the underlined word "tethers" in Paragraph 2 probably mean？
