I hate flying.这句如何翻译？
主人很好客，客人不知怎样谢绝。可否这样翻：The hosts are so hospitable that usually guests don’t know how to decline.
上海不比伦敦更挤。可否这样翻：It’s less crowded than London.
好象是当今的潮流，可否翻成：It seems a trend nowadays.
北京最有文化气氛？可否翻成：You said Beijng has the most cultural atmosphere?
因为有些翻的我很疑惑，所以请您帮我找出翻的不恰当的地方，非常感谢。

“I hate flying.”可以翻译为“我讨厌坐飞机”。

“主人很好客，客人不知怎样谢绝。”，我觉得你的翻译：“The hosts are so hospitable that usually guests don’t know how to decline.”没有问题。也可以考虑翻译成：“The hosts are so hospitable that usually guests would feel embarrassed to turn them down.”。

上海不比伦敦更挤。可以翻为：“Shanghai is not any crowdier than London.”

好象是当今的潮流，可以翻成：“Seems to be the trend today.”

北京最有文化？可以翻成：“Is Beijng the most cultural city ?”---硬要把“气氛”二字翻译出来便会变成中式英语了。假如是必要的话，可以考虑用“ambience”这字。“Do you find Beijing the city with the most cultural ambience ?”
