I’ll try to finish it in time, however hard it may be. 无论多么难，我也要按时完成。
④“however+形容词或副词+主语+谓语”有时可以有所省略。如：

I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小，我宁愿一个人住一间，而不愿意与别人合住一个房间。
A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则，不管如何正确，除非能懂，否则毫无用处。
