There are two tenses in English – past and present.
在英語(yǔ)里有兩種時(shí)態(tài)—過(guò)去時(shí)和現(xiàn)在時(shí)。

The present tenses in English are used:
現(xiàn)在時(shí)在英語(yǔ)里：

to talk about the present
可以描述現(xiàn)在

to talk about the future
可以描述將來(lái)

to talk about the past when we are telling a story in spoken English or when we are summarising a book, film, play etc.
在口語(yǔ)中講過(guò)去的故事或者在描述一本書(shū)、電影或者戲劇時(shí)，用現(xiàn)在時(shí)
