在剑桥KET考试中虽然没有直接考查语法知识的题目，但是语法蕴含于每一道题目中。阅读与写作、听力、口语都需要语法知识的储备。根据剑桥大学英语考评部发布的官方资料中关于A2(KET)考试的语法要求，总计为12类考点，55个语法知识点。瑞尔英语小编带你一起梳理核心语法点，精准夯实语法基础，顺利应对考试。
1. 过去进行时
用于谈论过去某个时间正在发生的事情
I was playing football at 3:30 yesterday.
用于谈论在过去某个时间同时发生的两件事
He was doing homework while his sister was watching TV.
过去进行时与一般过去时在同一个句子里出现的情况：
Iwas doing homework when mysister cameto talk to me.
Someone knocked at the doorwhilemy mother was cooking.
否定句、疑问句的表达方式:
He was not/wasn"t working.
They were not/weren"t speaking to each other.
Was he working?Yes, he was/No, he wasn"t.
Were they speaking to each other? Yes, they were/No, they weren"t.
2. can/can"t/could/couldn"t
在有些时候，could可以作为can的过去式使用
can/can"t表示能力，用于现在时
I canhelp you.(我能帮助你)
could/couldn"t表示能力，用于过去时，。比较：
I couldn"t come yesterday.(我昨天不能来)
I could havecome yesterday.(我昨天能来，但是没来)
can/can"t表示可能性，用于现在时
This can"t be true.(这不可能是真的)
could表示可能性，用于过去时，或者用于现在时但语气没有can强烈
He couldn"t go therewithout me.(他不可能不带我一起去)
can/could还可以在现在时中用于请求，区别在于could比can语气更委婉客气
Can you help me please?
Could you please open the door?
