請幫我判斷以下句子式屬於英語五大句型哪一種,感謝(框框的地方是我比較疑惑的地方,麻煩加以說明解釋為何) 1.She tried to convince the police (of her innocence)?

這是一個簡單句（simple sentence)：
主詞she＋及物動詞tried＋受詞（不定詞片語）
to convince someone of something是這個不定詞片語的語法結構
someone = the police
something = her innocence
不定詞是由動詞所衍生的動狀詞（verbal），所以具有動詞的部分特性。convince是及物動詞，所以其不定詞可以再接上自己的受詞somone，並連上介系詞片語of xxx當其修飾語。

To Yee-kwan:-
She (tried to convince);
=S + V + O as complement;infinitive phrase as verbal;

the police
=indirect object

of her innocence
=prepositional phrase ,as direct object.;
= preposition is a word that is used to show that word's connection with another word, such as" of "in of her innocence;, and" by" in by her innocence.

convince ----- of 是一個片語,( of her innocence)
主詞+動詞+to動詞+受詞+of(介係詞)+受詞
因為convince是不及物動詞,所以要加of再加一個受詞
