✔ 最佳答案
英文的動詞有 base form, present tense, present participle, past tense 和 past participle 的不同變化。
例：
be 是 base form
is / am / are 是 present tense
being 是 present participle
was / were 是 past tense
been 是 past participle
get 是 base form
get / gets 是 present tense
getting 是 present participle
got 是 past tense
got 是 past participle
而英文的 tenses 是用 verb 的不同形態，有些時還需要加一些輔助的字而成。
例： present continuous tense 是 be + present participle (例：is getting)
present perfect tense 是 have + past participle
past perfect tense 是 had + past participle
而 past perfect tense 最常用於表達兩件過去的事件，先發生的用 past perfect tense 而後發生的用 past tense.
問題裡的那段文字，我會略作修改：
A short time later, my sister arrived home. She had caught the wrong bus and got terribly lost. Luckily she had met a kind lady who br ought her home.
搭錯巴士發生在先，而迷路在後，所以我將搭錯巴士改為 past perfect tense.而 got lost 改為 past tense （取消了 had)）
因她遇到了那位很有愛心的女士在先，而那女士將她帶回家在後，had met 用 past perfect tense 而 brought 用 past tense.
p.s. Godfrey 其實已經給答了你的題目。
