2021年天水市中考对动词的考查主要涉及单项选择中出现的动词的时态、情态动词。完形填空、词汇考察中也涉及动词的时态，而任务型完形填空和句型转换涉及到了被动语态。预测2022年中考仍会从动词的时态、情态动词、被动语态等方面来考查，同时动词短语、非谓语动词也要作为复习的要点。
一.考情分析
1.基本变化形式（原形、单三、过去式、过去分词、-ing形式）
2.熟练掌握系动词be的用法和系动词become, turn, get, feel, look等的一般用法；情态动词must等的用法。
3.现在完成时态中的延续性动词和非延续性动词的转换也是考查重点
4.时态、语态（被动语态）、动词短语、非谓语动词（动词不定式）、主谓一致和一些习惯用语.
初中阶段要求学生掌握5种时态，即一般现在时、一般将来时、一般过去时、现在完成时、现在进行时；了解三种时态，即过去进行时、过去将来时、过去完成时。要做好时态题，一定要会在句子中找到相应的“关键词”，而这些词通常是表示时间的。另外，要熟悉每个动词的固定搭配的用法，还有不规则动词的各种变化形式。
二.动词的时态

（2）一般过去时表示过去发生的动作。be动词的一般过去时为was,were,实义动词的一般过去时为动词的过去式，常与just now, yesterday, last week/month/year,this morning,ago等表示过去的时间状语连用。
I ran into an old friend this morning.(改为一般疑问句)
_____ you _____ into an old friend this morning

（3）一般将来时由“shall/will+动词原形”构成，shall用于第一人称，will用于各种人称；此外还有“be going to+动词原形”的形式。常与tomorrow, next week等表示将来的时间状语连用。

2.宾语从句谓语动词的时态常常受到主句时态的影响，因而在使用时要注意主从句两部分的时态保持一致。一般要遵循以下原则：
① 主句是一般现在时，宾语从句的时态可以是任何适当的时态。所以，宾语从句的时态应根据实际情况而定。
She says(that) she works from Monday to Friday.她说她从周一至周五上班。（从句是一般现在时）
She says(that) she will sell the old books back to the school bookstore.她说她要把旧书卖给学校的书店。（从句是一般将来时）
She says(that) she has never seen the sea.
她说她从来没有见过大海。（从句是现在完成时）
② 主句是一般过去时，宾语从句的时态一般要用适当的过去时态。
He said there were no classes yesterday afternoon.
他说昨天下午没有课。（从句是一般过去时）
He said that he was going to buy some new books.
他说他打算去买一些新书。（从句是过去将来时）
He said that they were having a class at that time.
他说他们那时正在上课。（从句是过去进行时）
③ 当宾语从句是表示客观事实、普遍真理、自然现象等，不管主句用什么时态，从句时态都用一般现在时。
