GrammarB:Givingreasonswith“since/as”.While-learningWeuse“since/as”togiveaknownreason.(已知原因)Thereasonisknowntobothortoall.

眾所周知或雙方已知since表示顯然的或已為人所知的理由，自然的結(jié)果，常譯為“因為”、“既然”，語氣比because稍弱，通常置于句首。側(cè)重主句as表示的“原因”是雙方已知的事實或顯而易見的原因，或者理由不是很重要，只是對主句的附帶說明，含義與since相同，但語氣更弱，沒有since正式，常譯為“由于，鑒于”。主從并重，從句說原因，主句說結(jié)果for由于，表明附加理由（解釋或推斷），為并列句，for分句不放于句首,且必須用逗號與前面的分句隔開。語氣最弱。1.Hemustbeill,forheisabsenttoday。2.Itmusthaverainedlastnight,forthegroundiswet.WorkouttherulesA:Wealsousesinceorastointroduceclausesof______(known/unknown)reason.B:Thetone(語氣)ofsince/asis(weaker/stronger)thanbecause,C:We______(can/can’t)usesinceorastoanswerwhyquestions.D:We_______(never/often/sometimes)usetheconjunctionso
