【答案】Dear Peter，
I'm writing to share with you my opinion on whether it's worthwhile to explore Antarctica.
Antarctica is always a mysterious destination attracting brave souls to explore.For one thing，the exploration of Antarctica helps people better understand the problem of global warming.And for another，the bravery of explorers can encourage young people to explore the world.However，the weather conditions are terrible there and some explorers may even lose their lives.
But human beings cannot gain what we have achieved without paying a price.Besides，it is the extraordinary courage shown by the explorers that makes them into heroes.As long as people are well prepared，it will be much safer.
What about you？I am waiting to read your views.
Yours，
