Men wanted for difficult journey. Small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honor and recognition in case of success. Shackleton
1)What things you are good at.
2)Why you want to go to the South Pole.
3)Why you will be a useful member of the crew.
I’ve just learned about your journey from the newspaper and I decided to join you the instant（连词=as soon as) I saw it! It’s my dream to go on such a fantastic journey（形容词有感染力）! And this dream never fails to attract me（双重否定增加力度）.
Well, you may be disappointed as soon as you know that I’m a young girl, but I can ensure（保证） you that I’m never a person taken care of by others（过去分词）. I’m good at taking photos because it’s been my hobby for years. I will definitely be a useful member of your crew. Not only can I take photos of the highlights of the trip, but I also can keep a diary to help record the journey（很棒的not only倒装句型）. Your eyes may open wide, and your jaw may drop（眼睛大睁，下巴掉落，生动表达了“吃惊”） when you find my bravery and stamina（勇敢和耐力）!
I’ll be really grateful（不胜感激） if you allow me to join you! I won’t let you down（让你失望）. I’m lookingforward to your reply!
Dear Mr. Shackleton,
I’d like to join the crew of your ship and I hope you can consider my application（开门见山，简明扼要）.
When I was still a young boy, I often dreamed of living an exciting life.That’s why I chose to be a sailor when I grew up. But as time passed, being a sailor didn’t seem to appeal to me any more. I’m eager for somechanges. And here comes the chance. （上述加粗部分词汇用得很好）Dangerous though the trip is（尽管这个旅途危险，倒装不错）, I have made up my mind（下定决心）.
As I have said, I am a sailor. I’ve spent many years on the sea so I’m quite experienced. And I’m strong both physically and mentally（身心健康）. Whendifficulties come, I never surrender（屈服）. I can always get over（克服） them. I believeI will help a lot as a faithful companion（忠实的旅伴）.
Traveling to the South Pole is one of the greatest explorations in history. What you need（主语从句） are reliable（可靠的） friends and I’m sure that I won’t let you down.（有说服力的结尾）
I am writing in reply to your advertisement. I am willing to follow you to the South Pole.
I figure life is a gift and I do not intend on wasting it. Going to the South Pole may be the most exciting thing in the world. Not only will I have an opportunity to challenge myself, but I will also exercise my willpower. What is more important is that courage is something I never lack. As a result, I’d like to be one of your crew.
As I have some skills in first aid, I can help in case of emergency. It can be useful when we are on the inhospitable continent of Antarctica. And I am good at writing, too. I can keep our journey diaries, recording everything that happensduring our trip so as to provide some useful information for the next generation.
Please give me the chance and I won’t disappoint you. Trust me!
