人生不是上帝为谴责我们的缺陷而给我们布下的陷阱。人生也不是一场拼写比赛，不管你拼出多少单词，一旦出现了一个错误，就会前功尽弃。人生更像是一个棒球赛季，即使最好的球队也会输掉三分之一的比赛，即便最差的球队也有春风得意的日子。我们的目标就是多赢少输。当我们能够接受不完整是人性的一部分这个事实时，当我们的人生不断滚动并能欣赏其价值时，我们就会获得其他人仅渴望的完整人生。我相信这就是上帝对我们的要求：不求“完美”，不求“永不犯错”，而是求得人生的完整。

44.D

45.B

46.B解析：表示否定的副词前置于句首，句子需要不完全倒装，即助动词提前。其余选项均可排除。除Notuntil外还有never，seldom，rarely，seldom，no，little，hardly，innotime等否定副词或结构放在句首时，句子需要部分倒装。

47.A解析：favor：帮助，一般用domeafavor；good：好处；help不与do搭配：kindness：善良。故选A。
