我想知道Be动词在英语的时态中什么时候用，我经常弄混，？？？拜托大家了

Question

如题所述

Answer 1

be在一般现在时中遵循顺口溜：我(I)用am你(you)用are，is紧跟他(he)她(She)它(it)，复数人称都用are .
be在现在进行时中是be +Ving形式此时 be 用法同前.例如；Iam learning English.We are reading...
be在过去进行时中是be（was 、were） +Ving形式 be 用过去时.例如I was watching TV at six yesterday They were playing tennis yesterday afternoon
be 在被动语态中是be+动词的过去分词。be 根据时态而变化..例如The classroom was cleaned by Jim last week.
The classroom is cleaned by Jim every week.
The classroom will be cleaned by Jim next week.
The classroom has been cleaned by Jim .
The classroom can be cleaned by Jim
