I fell downstairs yesterday evening and hurt my left leg.__(ill) of all,nobody at home

I ____ downstairs when I fell.(run) i slipped and fell downstairs 为什么fell不用过去式 downstairs..I slipped and fell downstairs.George heard the noise and came downstairs puickly.这两个downstairs是什么词?做什么语呢? HE fell downstairs and hurt ()badly I fell downstairs yesterday evening and hurt my left leg.__(ill) of all,nobody at home If my grandmother fell downstairs and wasn't moving,I'd hurry to call the hospital first怎样翻译 downstairs I fell. I fell 初三英语书上READING的一个问题原句：If my grandmother fell downstairs and wasn't moving,I'd hurry to call the hospital first.我觉得grandmother是单三,所以fell应加s,请不吝赐教 If my grandmother fell downstairs and wasn't moving,I'd……为什么是wasn't,而不是weren't?为什么是要用“be doing的这种形式,而不是”couldn't move 我在楼下,用英语怎么说 是I 'm downstairs,还是I'm on downstairs i fell so i can stell fell I FELL you 是什么意思? I thought you fell i fell for I fell lonesome
