本题考查一般过去时和过去进行时的用法。一般过去时用于表示过去发生的动作或存在的状态，常和last Saturday night、later这类过去时间状语搭配；过去进行时用于表示过去某一时刻或时间段内正在进行的动作，常与at that time这类时间状语连用。
1. 问句询问过去是否看到奇怪的事，用一般过去时的一般疑问句结构“Did+主语+动词原形”，故填Did; see。
2. 回答过去看到的人，用一般过去时，see的过去式是saw。
3. 描述过去正在进行的“跑出小区”这个动作，用过去进行时，主语He是第三人称单数，故填was running。
4. 根据at that time可知，此处表示过去某一时刻正在进行的动作，用过去进行时，主语I对应的be动词是was，故填was watching。
5. 描述过去听到声音的动作，用一般过去时，hear的过去式是heard。
6. 描述过去出去的动作，用一般过去时，go的过去式是went。
7. 表示当时正在发生的事情，用过去进行时，what视为单数，故填was happening。
8. 问句询问过去是否注意到其他事，用一般过去时的一般疑问句结构“Did+主语+动词原形”，故填Did; notice。
9. 描述过去觉得累的状态，用一般过去时，feel的过去式是felt。
10. 描述过去去睡觉的动作，用一般过去时，go的过去式是went。

b broke; was sent
c has broken; has been sent

1. a；2. b；3. b；4. c；5. b

1. 句中"three times"体现经历，"has been to"表示“去过某地（已返回）”，符合语境；"has gone to"指“去了某地（未返回）”，"went"仅表过去动作，无强调经历的作用，故选a。
2. "the other day"是一般过去时的标志词，一般过去时的特殊疑问句需借助助动词did，动词用原形，故选b。
3. "so far"（到目前为止）是现在完成时的标志词，现在完成时结构为“have/has+过去分词”，故选b。
4. "Until now"（直到现在）是现在完成时的标志词，write的过去分词是written，现在完成时结构为“have/has+过去分词”，故选c。
5. "two hours ago"是一般过去时的标志词，第一个空用一般过去时broke；第二个空表示“被送去医院”，是过去的被动动作，用一般过去时的被动语态was sent，故选b。
