4. Though I had no time to travel, I still felt happy.
虽然我没有时间去旅行，但我仍然感到很开心。
① though/although 和 even though/even if 意为“虽 然；尽管；即使”，引导让步状语从句，通常不与but连用。
even though/even if带有强调的意味，语气较强；though和although语气较弱，而thought比although更口语化，不如although正式。
eg: Though/Although it rained, the boys still played outside.
= It rained, but the boys still played outside.
尽管天下雨了，但是那些男孩子仍在外面玩。
