英语翻译DJ okawari的flower dance,开头有一段男女英文对话的,求翻译!

原文：Woman:"They serve the purpose of changing hydrogen into breathable oxygen.And they’re as necessary here as the air is,on Earth.”
Man:"But I still say,they're flowers".
Woman:"If you like..."
Man:"Do you sell them?"
Woman:"I afraid not."
Man:"But,maybe we could make a deal?"
译文：女：“它们的作用就是把氢气转化为可呼吸的氧气,并且它们对这地球上的空气是很重要的.”男：“但我还是要说,它们是花.”女：“如果你喜欢的话·····”男：“你能把它们卖给我吗?”女：“我恐怕不行.”男：“但是,或许我们可以做一个协定?” 半吊子翻译,但应该不会影响阅读··············································
