pasttense？tense怎样区别啊

一、past***tense和past***continue***tense怎样区别啊

Simple Past（过去式）

Simple Past Tense是表达一个过去及已经结束的动作，而这个动作必须给予一个清楚的时间。简单而言，就是如果我们在知道时间的情况下，我们会用 Past Tense，相反如果不知道时间，我们会用 Present Perfect（continuous）Tense，或 Past Perfect（Continuous）Tense，视乎情况。

因为它的用途基本上得一个，所以我亦不会详谈（实在是没什麼可谈…）。不过它还有一个用法上要注意的地方：

Past Continuous Tense（过去进行式）

它的用法与 Present Continuous Tense相同，只是时态是过去式罢了。

E.g.：I saw Miss Tam yesterday. She was waiting for a bus.

其次，当我们讲故事时，都会用 Past Continuous Tense来描述故事背景，以其他 Past Tenses来表达事件及动作。

E.g.：I was waiting for a bus. Suddenly I saw a black car stop in front of a bank. Some men got out of the car and rushed into the bank. Soon I heard…

二、past continuous tense的用法

进行式(continuous tense)应该大家都听过，最常见系现在进行式(present continuous tense)，就例如 Mr Kum is eating an banana(Mr Kum食紧蕉)，系讲紧呢一刻正在「做紧」一个动作，就好似岩岩个「食紧蕉」咁。过去进行式都差唔多，系讲「在一个过去的指定时间做紧既一个动作」，就例如... At 10 pm last night

I was watching TV.(寻晚十点，我睇紧电视)系英文里面，如果讲紧在过去的一刻(如讲明几多点)做紧乜时，就会用过去进行式。以之前果句为例，watch呢个动作系十点前已经开始左，所以到十点时就系睇紧(watching)。而 watch呢个动作系十点后可能还会继续。但如果冇明确讲明时间的话，就通常唔会用过去进行式，例如以下呢句系错既: Yesterday I was playing basketball with Alex.(寻日我同 Alex打紧波)呢句用左过去进行式，即系讲紧个动作系 yesterday之前(例如前日)已经开始左，到讲野果一刻仍然做紧。但好明显我地唔系讲紧呢样野。如果净系想讲一个过去左既动作，用 simple past(简单过去式)就可以: Yesterday I played basketball with Alex.(寻日我同 Alex打波)仲有一个情况都要用过去进行式，就系讲「一样野发生紧时，有第二样野突然发生」，例如: While I was playing football with Alex

William called me.寻日我同 Alex打紧波时，William打俾我。可以见到「长d」果个动作，即一直做紧果个，系用过去进行式(while I was playing basketball)，「短d」果个，即期间发生果个，系用简单过去式(called me)。 While多数系用黎讲长d既动作，如上面果句 While I was playing football...，而 when就系引出短d既动作，例如: We were having dinner when the phone rang.就系咁，总知想讲过去做紧一样野时，就要用 past continuous tense，但要记着所谓做紧，即系在指定时间期间正在进行。

三、past tense 与 present prefect tense的分别

Simple Past(简单过去式): Subject Verb(动词过去式)当一件事情在过去已经发生并完成左(不论系一秒前

或一万年前)例句: I just missed the bus! Now I'm going to be late for school. When dinosaurs walked the earth

there were no hum. Present Perfect Tense(现在完成式): Subject have/has past participle of verb(过去分词) a.一件事开始时是过去

一直持续到现在 She has worked on the same job for 20 years.(佢20年前开始做呢份工

做到今日仲做紧

所以用现在完成式) b.一件事在过去已经完成

但可能会再发生 We have had three tests this semester.(由学期开始到而家已经有3个测验

由于学期未结束

可能仲有更多测验) c.一件事在过去已经完成

但无确实讲明系几时完成(或根本唔重要) I have seen that movie. He has read that book.但当如果有问几时

个答案就会变成简单过去式.如: A: I have seen that movie. B: When? A: I saw it yesterday.

Past tense用法简单

它是表示过去的动作

状态

事实

大致和表示过去的副词如: yesterday

last week等连用而Present prefect tense 1.它表示动作刚刚完成的动作或状态 e.g He has left for China他刚去了中国 2.凡表示过去

到现在已完成或还在继续

须用 Present prefect tense e.g. I have stuided English for five year.我英文读了五年了.(虽然已经读了五年

现在却还在继续读。) Hope these are useful for you<>??

(6)过去将来时：would be 过去分词。如：
