33、項B這樣的選項。也就是說下列結構是錯誤的：It was a hot day, they went swimming.nIt was a hot day, and they went swimming.nSince it was a hot day, they went swimming.n注：英語的語法是顯性的，句子之間的各種關系要體現(xiàn)在形式上，而漢語的語法則是隱形的，句子之間的各種關系要語義來傳達。非謂語動詞分詞n2）作狀語小練習：把句子改為分詞結構n1.As the secretary was away, Mr. Green had to type his final grade.n2.S
