How( )the boy (fall)off his bike just now?用括号内所给词的适当形式填空
问题描述：
How( )the boy (fall)off his bike just now?用括号内所给词的适当形式填空
How ———the boy—— (fall)off his bike just now?
横线上填空
答
How(did )the boy (fall)off his bike just now?
分析 just now 刚才,用一般过去时
加油!不明白再问!还有其他答案吗？比如：How was the boy 摔倒的 off his bike just now? 还有楼上的回答：How (has) the boy (fallen) off his bike just now?没有，你列举的两个答案都不对，因为just now 刚才（不能与现在完成时连用），要用一般过去时，实义动词作谓语，要加助动词did ，后面的动词要用原形，即fall 不变How(did)the boy (fall)off his bike just now?这个男孩刚才是怎样从自行车上摔下来的？
真是太感谢了
