会议上有难的紧张气氛。

A pause followed this apparently pointless remark. Daisy looked at Tom frowning and an indefinable expression, at once definitely unfamiliar and vaguely recognizable, as if I had only heard it described in words, passed over Gatsby's face.

这句似乎没有什么意义的话说之后，大家沉默了会。黛西皱着眉头瞧瞧汤姆，同时盖茨比脸上掠难形容的表情，既十分陌生又似曾相识，仿佛我前只是听人用言语似的。
