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.He was very dissatisfied (at not getting the bonus).?

這是一個簡單句（simple sentence）：
主詞He + 不完全不及物動詞was ＋主詞補語dissatisfied
at not getting the bonus是「介系詞片語」，是修飾述部was very dissatisfied的修飾語。
getting是動名詞，bonus是其受詞；getting the bonus當介系詞at的受詞。

He was very dissatisfied (at not getting the bonus）.

他“因為沒得到獎金”而感到極為不滿。

☆ (at not getting the bonus）是 用作修飾「dissatisfied」
