进行时态

构成并使用进行（连续）动词时态——过去进行时（was walking）、现在进行时（am walking）和将来进行时（will be walking）——来表达不同时间内正在进行的动作。

Form and use the progressive (continuous) verb tenses — past progressive (was walking), present progressive (am walking), and future progressive (will be walking) — to convey ongoing actions at different times

学习证据 / Evidence

• 用过去进行时写句子，描述在特定时间正在进行的动作，例如“She was reading when the phone rang”。
• 区分现在进行时和一般现在时，例如“I am eating lunch”（此刻正在吃）和“I eat lunch at noon”（习惯性动作）。
• 用“will be”加现在分词构成将来进行时，描述将来某个时间正在进行的动作，例如“Tomorrow at 3pm I will be travelling”。

• Write sentences using past progressive to describe an action that was ongoing at a particular time, e.g. 'She was reading when the phone rang'
• Distinguish present progressive from simple present, e.g. 'I am eating lunch' (right now) vs 'I eat lunch at noon' (habitual)
• Form the future progressive using 'will be' + present participle to describe an action that will be ongoing, e.g. 'Tomorrow at 3pm I will be travelling'

评估问题 / Assessment

如果 {{name}} 想描述过去一段时间内正在发生的动作，比如“I was reading when the phone rang”，{{name}} 能用正确的过去进行时形式写出这个动词吗？

If {{name}} wants to describe an action that was happening over a period of time in the past — like "I was reading when the phone rang" — can they write the verb in the right ongoing-past form?
