動詞時態是英語考試必考內容，很多同學在做題的時候很難判斷出時態類型，如果能用心記住這些英語動詞時態標誌詞，那麼在題目中看到它們的時候，你就能快速辨析出時態類型啦～
巧用時態標誌
任何一種時態都有潛在的標誌，巧用這些標誌可以妙解時態試題。
一.巧用特定時間點，妙解進行時試題
進行時往往表示某一特定動作在特定時間點正在進行。過去進行時表示某一動作在過去某一特定時間點正在進行，這一過去特定時間點就是過去進行時存在的標誌。過
去特定時間點可由just now，at eight o』clock yesterday evening，just at that time，at the time，at this time yesterday等直接時間狀語和when，while，as引導的時間狀語從句體現，也可由上下文語境體現。
Did you see a man in black pass by just now?
No，sir. I ____ a newspaper.
A. readB. was readingC. would readD. am reading
析：B。just now暗示空檔表達「剛才正在讀」的動作概念，為過去進行時標誌，因此該空應填was reading。
It was really very kind of you to give me a lift home.
Oh，don』t mention it. I ____ past your house anyway.
A. was comingB. will comeC. had comeD. have come
析：A。分析語境邏輯可知，空檔表達「剛才正路過」的動作概念，為過去進行時的標誌，因此該空應填was coming。
Is there anything wrong，Bob? You look sad.
Oh，nothing much. In fact，I ____ of my friends back home.
A. have just thoughtB. was just thinking
C. would just thinkD. will just be thinking
析：B。分析語境邏輯可以推出空檔表達「剛才正在想念」的動作概念，因此應用過去進行時。
現在進行時表示某一動作現在正在進行，因此現在這一特定時間點就是現在進行時存在的標誌。現在這一特定時間點常由now，at present等時間狀語或上下文語境體現。
What’s that terrible noise?
The neighbors ____ for a party.
A. have preparedB. are preparing
C. prepareD. will prepare
析：B。What’s that terrible noise?暗示鄰居此刻正在為晚會做準備，它實際上是該句運用現在進行時的標誌，因此該空應填are preparing。
將來進行時表示某一動作在將來某一特定時間點正在進行，因此將來某一特定時間點就是將來進行時存在的標誌。將來某一特定時間點可由at six o』clock tomorrow morning，at this time tomorrow等時間狀語或上下文語境體現。
At this time tomorrow ____ over the Atlantic.
A. we』re going to flyB. we』ll be flying
C. we』ll flyD. we』re to fly
析：B。at this time tomorrow屬未來特定時間點，為將來進行時標誌，因此該空應填we』ll be flying。
二，巧用標準對照時間點，妙解完成時試題
眾所周知，現在完成時表示某一動作相對於現在來說已經完成，或發生在過去某一時刻的動作一直延續到現在，因此現在是現在完成時標準對照時間點，尋找這一標準對照時間點可以妙解現在完成時試題。
Danny ____ hard for long to realize his dream and now he is popular.
A. worksB. is workingC. has workedD. worked
析：C。and now he is popular表明Danny自過去某一時刻開始努力工作的動作到現在為止已有很長時間，因此該空應用現在完成時。
____ you ____ him around the museum yet?
Yes. We had a great time there.
A. Have;shownB. Do;showC. Had;shownD. Did;show
析：A。yet暗示問句表示「到現在為止你領他參觀了博物館嗎?」，因此空檔應用現在完成時。
過去完成時表明某一動作相對於過去某一特定時刻來說已經完成，或發生在過去某一時刻的動作一直延續到過去另一時刻，其標準對照時間點為過去某一特定時刻，尋找這一標準對照時間點可以妙解過去完成時試題。
I ____ there little more than a week when I set to work with the scientist.
A. would beB. have beenC. had beenD. will be
析：C。分析語境邏輯可知，題干表示「開始和這個科學家工作時我已經在那兒呆了一個星期多一點」，因此空檔應用過去完成時。
Did Alan enjoy seeing his old friends yesterday?
Yes，he did. He ____ his old friends for a long time.
A. didn』t seeB. wouldn』t seeC. hasn』t seenD. hadn』t seen
析：D。分析語境邏輯可知，該空表示「昨天以前沒有看到」，因此應用過去完成時。
They became friends again that day. Until then，they ____ to each other for nearly two years.
A. didn』t speakB. hadn』t spoken
C. haven』t spokenD. haven』t been speaking
析：B。由語境邏輯可以推出空檔表示「在became friends所表示的時間之前幾乎兩年沒有講話」，因此應用過去完成時。
現在/過去完成進行時往往表示發生在過去某一特定時刻的動作一直延續到現在/過去另一特定時刻，並且在這段時間之內動作一直沒有停止過，因此現在/過去某一特定時刻也是現在/過去完成進行時的標準對照時間點。
I have got a headache.
No wonder. You ____ in front of that computer too long.
A. workB. are working
C. have been workingD. worked
析：C。分析語境邏輯可知，空檔表示在到現在為止too long所體現的時間範圍之內主人公工作的動作一直沒有停止過，因此應用現在完成進行時。
The crazy fans ____ patiently for two hours，and they would wait till the movie star arrived.
A. were waitingB. had been waiting
C. had waitedD. would wait

Cathy is taking notes of the grammatical rules in class at Sunshine School，where she ____ English for a year.
A. studiesB. studied
C. is studyingD. has been studying
析：D。從一年前到現在，Cathy學英語的動作一直在進行著，因此空檔應用現在完成進行時。
三巧用未來時間標誌，妙解將來時試題
一般/過去將來時往往表示某一動作在現在/過去某一時刻的將來發生，因此分析語境邏輯尋找以現在/過去某一時刻為標準的未來時間標誌，可以妙解一般/過去將來時試題。
以現在為標準的未來時間標誌可由tomorrow，the day after tomorrow，in a month，next year等時間狀語體現，也可由上下文語境體現;以過去某一時刻為標準的未來時間標誌可由the next month，after a week等時間狀語或上下文語境體現。

I ____，but I suddenly remembered I had homework to do.
A. had toB. didn』tC. was going toD. wouldn』t
析：C。由but I suddenly remembered I had homework to do的語境邏輯可以推出空檔表示「(相對於過去某一時刻來說)正準備來」，因此應用過去將來時。
條件/時間狀語從句應用一般現在/過去時代替一般/過去將來時;come，go，leave，arrive，start，fly，drive，open，close等動詞常用一般現在時/過去時或現在/過去進行時代替一般/過去將來時。

A. persuadeB. will persuadeC. be persuadedD. are persuaded
析：D。will be reduced表明空檔為一般將來時，但因所在句為條件狀語從句，因此應由一般現在時代替。
Because the shop ____，all the T-shirts are sold at half price.
A. has closed downB. closed down
C. is closing downD. had closed down
析：C。由all the T-shirts are sold at half price可以推出空檔表示「(相對於現在來說)即將關閉」，因此可以用現在進行時代替一般將來時。
四.巧用經常性動作標誌，妙解一般時試題
一般時往往表示經常性、習慣性動作，尋找現在/過去經常性動作標誌可以妙解一般現在/過去時。
現在/過去經常性動作標誌常由always，usually，often，sometimes，seldom，never等表示時間的頻度副詞體現，也可以由上下文語境體現;過去經常性動作標誌也可由last month，in 2000等過去性時間狀語體現。
一般過去時也可以表示過去的一次性動作或狀態。
