變成并列句：i was so tired this morning so it was difficult for me to get out of bed變成結果狀語從句i was so tired this morning that it was difficult for me to get out of bed格式是i was______tired________i couldnot getout ofbed this morning第一個空填so 第二個空填that這是一個結果狀語從句，我早晨太累了以至于沒法兒起床看到有was和could not兩個動詞，就可以知道這是要填連接詞變成從句（因為一個簡單句只能有一個謂語動詞）然后在看兩個句子的邏輯關系，沒辦法起床是太累了的結果，所以填so that變成結果狀語從句
