為了讓你明白我盡量並用中英文解答閣下的問題^^
首先, perfect tense 中我們常會用到的有3種:

--------------------------------------------------------------------
i.)PAST PERFECT(舊名pluperfect)

Formation:
'HAD' + Past Participle

A. For actions that happened before related past events or times.
A. 過去發生的事, 被再之前發生的舊事關係到或影響到


eg A1: When she arrived, all the tickets had gone.
例 A1: 當她抵達時, 戲票早己不見了!
(只須留意tickets had gone, 比she arrived更早發生, 閣下便會明白)

eg A2: I'd never heard of it until last week.
例 A2: 我還未得知此事直至上星期!
(只須留意I'd never heard, 比last week更早發生, 閣下便會明白)


---------------------------------------------------------------------------------
ii.)PRESENT PERFECT

Formation:
'HAVE' + Past Participle

A. For unfinished past actions
A. 直至此刻還未完的事

eg A: I've worked here for four years.
例 A: 我在這裡做了四年工作.
(留意時間, 直至此刻, 我還是做這份工作, 閣下便會明白)

B. For past actions when the time is not specified.
B. 已過去的事情, 唯不清楚發生時間

eg B: Have you ever been to Rome?
例 B: 你到過羅馬嗎?
(留意是問別人, 直至此刻, 去過羅馬沒有)

C. When a past action is relevant now.
C. 過去的事情會影響或關係到現在.

eg C1: I've missed my flight.
例 C1: 我己經錯過了我的飛機航班
(留意時間, 過去錯過了)

eg C2: She's broken her leg and cannot go on holiday next week.
例 C2: 她斷了腳, 所以下星期放假不能去
(過去斷了腳, 直至此刻未能痊癒, 不能去)
----------------------------------------------------------------------------------------------------
iii.) Future Perfect

Formation:
WILL HAVE + Past Participle

A. For actions to be completed before a specific future time, but the exact time is unimportant.
A 談及一件將來某時間前發生的事, 但不確實何時, 肯定的只是該時間前

eg A: She'll have finished it by next week.
例 A: 她將會在下星期前完成的.
(留意, 時間是將會, 預計 will have finished 比 next weekend 早發生)


B. When making assumptions about actions that are finished now.
B 對一些現在完成了的事做假設

eg B: It's OK to phone because he'll have got home by now.
例 B: 現在可以致電他了, 他該回了家呢!
(這裡假設''他回家了'', 所以用 he will have got home, 然後, 我們可以致電給他 OK to phone)

======================================================
以上3種是常用的
希望你能明白
緊記留意事情發生先後, 然後作時間比較
(例:A先還是B先? AB兩事件都過了去嗎?
A過去了但B直至現在的? 還是B直至將來的?)
那就可以事半功倍

ps
另外還有1種有別以上3種, 但同時用了PAST PERFECT (上面的i, 舊名pluperfect)
----> third Conditional tense
不過是屬於conditional tense(可能發生, 假設性的 tense)
通常句子中會有 If (如果) 等等

還有提提你adjective同adverb主要分別:
urgently是adverb
adverb 主要是用來形容verb(動詞)
例. I have to finish the case urgently.
(urgently在這裡形容了動詞finish)

urgent是adjective
adjective主要是用來形容noun(名詞)
例. The case is urgent.
(urgent在這裡形容名詞case)

這一定要分清楚喔~
最後祝你考試成功^^
