dueto,thanksto,becauseof,owingto共同點(diǎn)：都有“由于”“因?yàn)椤钡囊馑?，都是介詞短語，

因此后面不可接從句或動(dòng)詞不定式。不同點(diǎn)：1)dueto一般只用作表語。2)becauseof只能用作狀語。3)owingto既可以用作狀語，也可以用作表語，平常多用于前一種情況，它引導(dǎo)的狀語必須是修飾全句的，因此嚴(yán)格來講應(yīng)用逗號(hào)和主句分開。4)thanksto只能用作狀語，可以表達(dá)正面意思，“幸虧”，也可用于諷刺口吻中(近于諷刺口吻的“感謝”)?！菊Z境應(yīng)用】根據(jù)漢語意思完成句子。1)Thepolicemansaidtheaccidentlastnightwas_____________driving.
