since語氣：because>since>as塊頭大，語氣強。because從句語義重心在分句上。since/as從句語義重心在主句上。because用于回答why提問的問題，可獨立成句。because和so不能同時出現(xiàn)在一個句子中。I'mtiredbecause

Ididn'ssleepverywell.Let'sstartourparty,sinceeveryoneishere.含義:because引導(dǎo)直接、充分的原因，常譯作“因為”；since,as引導(dǎo)顯而易見或間接的原因，常譯作“既然、由于、鑒于”。BecauseTomisill,hedoesn'tcometoschool.Sinceyouareill,you'dbetterstayathome.-Whydoesn'tTomgotoschooltoday?-Becauseheisill.BecauseTomisill,sohedoesn'tcometoschool.×語氣含義because用法GrammardiscoveryBecauseof
