A group of scientists discovered a gas called phosphine on Venus （金星） .That means there may be living things on the planet.This made many people start to imagine the talk between aliens and humans.Imagining himself as the life on Venus，a reporter from No.I Middle School wrote the following letter to people of Earth on the school newspaper.

Attention，People of Earth!    Fine.The big secret is out.Many of your finest scientists have discovered there is life tens of millions of miles away--here，on the beautiful planet of Venus.Congratulations!However，we are asking you：Please stay away.    We're serious.We are not interested.No spacecrafts to Venus，no exploring tasks，no visits.If we wake up one morning and find so many of you people walking around in spacesuits，we're going to be really sad.    We don't want to be impoljye.aie.It's just that we're quite surprised and unpleasant by what you've been going on down there.Earth is in a mess.There are too many cars running on the roads，which creates lots of traffic jams.Many people suffer from serious illnesses.Some people do great damage to the forests and rivers.What's worse，there are even fights between countries，etc.No wonder so many of you want to leave Earth for another planet.    Leave us alone.Keep right where you are.We know you'd like it here.That's what frightens us.You'd all move to our planet at once.If we start having you all up here，pretty soon，the other aliens like Martians and Jupiterians are going to come，too.But we can't imagine what terrible things will happen to us!Venus is not Earth.It's not your home.We suggest Earth people▲.It is a practical way to save you and your future generations.    God bless you!
