錯誤百出的句子

Question

 the direct medical cost associated with diabetes from 44 billion in 1997 has double to 92 billion in 2002請問這句要怎麽改才正確？？

Answer 1

The direct medical cost assoicated with diabetes was $44 billion in 1997 and doubled to $92 billion in 2002.

與糖尿病有關的直接醫療成本從1997年的440億到2002年增加了一倍。

silentwf: 我也考慮過保留發問者用現在完成式來表達數字的「加倍」(has doubled)。後來還是決定用過去式"doubled"，主要原因是因為「加倍」這個動作是數字達到兩倍那一剎那出現的。"double"和別的動詞不一樣，它不會在過去一段時間中「持續發生」，所以不能用完成式，不知以為然否？

Answer 2

這種費用增加的統計的確是持續發生的，不過因為時間點已經過去(2002)，所以要用完程式也應該用過去完成式"had doubled"，各位覺得呢?

Answer 3

the direct medical cost associated with diabetes from 44 billion in 1997 has double to 92 billion in 2002

[The] direct medical cost associated with diabetes from [$]44 billion[,] in 1997 [,]has [doubled] to [$]92 billion[,] in 2002[.]
