变成并列句：i was so tired this morning so it was difficult for me to get out of bed变成结果状语从句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第一个空填so 第二个空填that这是一个结果状语从句，我早晨太累了以至于没法儿起床看到有was和could not两个动词，就可以知道这是要填连接词变成从句（因为一个简单句只能有一个谓语动词）然后在看两个句子的逻辑关系，没办法起床是太累了的结果，所以填so that变成结果状语从句
