Clauses of concession use although/even though + subject + verb. A reason can use because + clause; a result can use so + clause. Do not pair although with but or because with so in the same two-clause construction. Despite/in spite of take a noun or V-ing,not a complete clause without “the fact that”.
A statement can function as a checking question with rising intonation: “You want to be an engineer?” The word order remains a statement; the rise signals confirmation or surprise. Use a genuine curious tone,not disbelief that dismisses a classmate’s ambition.
