解析
【分析】本题考查动词时态的运用，需结合语境和时间状语（如while、when引导的从句）判断动作的时态：过去进行时表过去某一时刻/段时间正在进行的动作，一般过去时表过去发生的动作，一般将来时表将来的计划。解题时，先确定每个空对应的动作发生的时间背景，再根据主语的单复数、动作的状态（正在进行/已完成）选择正确的动词形式。
【解析】
1. 动作“walk”发生在“我经过公园看到她们”时，是过去某一时刻正在进行的动作，主语为复数they，故用过去进行时were walking。
2. while引导的时间状语从句，主句动作“ran”是过去发生的，从句动作“watch”是当时正在进行的，主语为I，故用过去进行时was watching。
3. 动作“begin”是过去发生的、已完成的动作，用一般过去时，begin的过去式为began。
4. 由“when I grow up”可知，动作“become”是将来的计划，故用一般将来时will become或am going to become。
5. while引导的时间状语从句，主句动作“happened”是过去发生的，从句动作“talk”是当时正在进行的，主语为Lily，故用过去进行时was talking。
6. while引导的时间状语从句，主句动作“fell down”是过去发生的，从句动作“run”是当时正在进行的，主语为he，故用过去进行时was running。
7. 动作“go”是过去发生的、已完成的动作，用一般过去时，go的过去式为went。
8. when引导的时间状语从句，主句动作“arrived”是过去发生的，从句动作“discuss”是当时正在进行的，主语为we，故用过去进行时were discussing。
9. 动作“call”是过去发生的、已完成的动作，用一般过去时，call的过去式为called。
10. while引导的时间状语从句，主句动作“happened”是过去发生的，从句动作“wait”是当时正在进行的，主语为all of us，故用过去进行时were waiting。
【答案】1. were walking 2. was watching 3. began 4. will become / am going to become 5. was talking 6. was running 7. went 8. were discussing 9. called 10. were waiting
【知识点】动词时态；时间状语从句的时态用法
【点评】本题围绕过去进行时、一般过去时和一般将来时的核心用法展开，重点考查while/when引导的时间状语从句中时态的搭配，需准确判断动作的时间状态，是初中英语语法填空的高频考点，难度适中。
