If it had not been for your timely assistance in giving me first aid, I fear that the consequences might have been much serious.

it had not been for your timely assistance in giving me first aid这句话的语法结购是啥啊?能帮我分析下吗?感谢

“要不是你及时的采取急救措施来帮我，恐怕我的后果会很严重。”
if引导的是虚拟条件句。"If it ..not for..."（要不是。。。。）
在这个从句中。it为主语，had not been 为系动词be的过去完成式, for your timely assistance in giving me first aid 为介词短语做表语。而系动词+表语构成英语中的谓语。

是虚拟语气，表示与过去事实相反
句子意思是：要不是你及时给我采取了急救措施，恐怕结果会更加糟糕。

与过去事实相反的从句，要用过去完成时，主句用would/might/could have done

IF后的从句使用了虚拟语气 had been ,后面主句用would/could/should/might have done形式

it had not been for 表示“如果不是因为”的意思

your timely assistance in giving me first aid

assistance in为固定搭配，in后面用ing形式，后面意思是 及时给我急救
