一、概念:经常、反复发生的动作或行为及现在的某种状况。 二、常搭配的时间状语:

①be动词(is,am,are);②行为动词(主语是第三人称单数时谓语动词要加s或es外) 否定形式:①am/is/are+not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。例句:
I go to school at 6 every morning. 每天早上我七点去上学。 Summer follows spring. 春天之后是夏天。

在这种情景中,句子常带有表示频率的时间状语:always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等,以表示句中的动作或状态是习惯性的、经常性的。例如:
They raise ducks as a sideline .他们以养鸭为副业。
She doesn't often write to her family, only once a month. 她不常给家里写信,仅一月一封而已。
I cycle to work every day .我每天骑自行车上班。 It seldom rains here .这儿很少下雨。
2)仅为了描述状态、性质、特征、能力等等。
这里的目的是为了\描述现阶段的动作或状态\,其重点\不是强调动作发生的时间、或进行的状态\。例如:
He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。
Changjiang River is one of the longest rivers in the world. 长江是世界上最长河流之一。 She majors in music .她主修音乐。
All my family love football .我全家人都喜欢足球。(强调每个家人) My sister is always ready to help others . 我妹妹总是乐于助人。 3) 陈述客观事实、客观真理。
顾名思义,客观的情况是\没有时间概念\的;也\不会在意动作进行的状态\。例如: The earth goes around the sun .地球绕着太阳转。 Ten minus two is eight.十减二等于八。
Light travels faster than sound .光的速度比声音的速度快。
The United States lies by the west coast of the Pacific Ocean. 美国位于太平洋西岸。 4) 根据英文语法规定,当主句的谓语动词是一般将来时,那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如:
I'll tell him the news when he comes back. 他回来时,我将告诉他这个消息。 If you take the job , they will talk with you in greater details. 如果你接受这份工作,他们将和你谈谈细节。
用于一般现在时的副词,除了上面提到的一些表示频率的词以外,常见的还有:now,

一般过去时
一、概念:过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为。 二、常搭配的时间状语:
ago, yesterday, the day before yesterday, last week(year, night, month?), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc. 三、基本结构:
①be动词的过去式(was/were);
②行为动词的过去式(即在动词原形后加ed,不规则变化的动词除外) 否定形式:①was/were+not;②在行为动词前加didn't,同时还原行为动词。
一般疑问句:①was或were放于句首;②用助动词do的过去式did 提问,同时还原行为动词。
一般过去时用谓语动词的过去式构成,即在动词原形后加ed,不规则变化的特殊动词除
外。例句:
He was here just now. 他刚才还在这里。 What did you do yesterday? 你昨天做了什么事?
We often played together when we were children. 我们小时候常在一起玩。 He used to smoke a lot, but he doesn’t now. 他过去经常抽烟,但现在不抽了。 四、基本用法
主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。这一点在表达意义上与一般现在时相同,只是所在的时间区域不同而已。由于它的主要作用如此,所以在使用一般过去时的句子里常常有一个意义较具体的过去时间状语。这也是它与现在完成时的最大区别之一。
常和一般过去时连用的过去时间状语有:last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 使用一般过去时,在某种意义上说就是要强调动作或状态发生或存在于过去的某个
