She considered herself lucky that she had insurance when she was diagnosed with breast cancer.請問名詞子句that she had ，，在句中文法關係？

名詞子句 "that she had ,,," 在句中的作用是形容詞"lucky"的補語, 提供完整資訊說明幸運的內容(what was lucky?).

註: the that-clause functions as noun to give complete information (but not adverb to indicate reason) and to complement (but not modify) the adjective "lucky".

1，She considered herself lucky that she had insurance when she was diagnosed with breast cancer.其中that she had------ 文法上係that引導子句當副詞用表原因且修飾其前受訶補語lucky

2，本句文法結構為:S+Vt+O+OC

Reference to your recommended  TW Chen's the heart of grammar book "20 marks demanded":-
This pattern is for the verb be=consider
The verb is followed by a noun or pronoun and a that-clause.She considered----S+vtherself----noun/pronounlucky(girl)-----adj(that)----conj.she had insurance----introducing Noun Clause of result and purpose, Not condition, cause, reason; as complement only to "lucky""girl"when------relative adverb   she was diagnosed----that was diagnosed=a that clause;with breast cancer------prep.phrase.follow that clause adverbial;

她在證實患癌前已買重保險，這是相當好運
