八种常用时态讲解
初中英语动词时态1、一般现在时主要用于下面几情况：1) 描述当前时间经常出现、反复发生的动作或存在的状态。
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. 长江是世界上最长的河流之一。
She majors in music .她主修音乐。
All my family love football .我全家人都喜欢足球。
My sister is always ready to help others . 我妹妹总是乐于助人。
3) 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"。
