被动语态和主动语态怎么区别呢？
八大时态主动语态和被动语态如下：
（1）一般现在时：am/is/are+过去分词。如：
Rice is grown in south China.华南种植水稻。
（2）一般过去时：was/were+过去分词。如：
The glass was broken yesterday.这块玻璃是昨天打烂的。
（3）现在进行时：am/is/are being+过去分词。如：
The project is being carried out.这个计划正在执行中。
（4）过去进行时：was/were being+过去分词。如：
This road was being built this time last year.这条路去年这个时候还在修建。
（5）一般将来时：will be+过去分词。如：
The cars will be sent abroad by sea.这些汽车将由水路运往国外。
（6）过去将来时：would be+过去分词。如：
The manager said the project would be completed by the end of the year.经理说这个工程在年底前将会完成。
（7）现在完成时：have/has been+过去分词。如：
This novel has been translated into several languages.这本小说已被译成了几种语言。
（8）过去完在时：had been+过去分词。如：
When I got to the theatre,I found the tickets had already been sold out.我到达剧院时，发现票已卖完了。
被动语态的构成：
助动词be+及物动词的过去分词+（by+宾语）其中by意为“被~；由~”，表动作的执行者。
如：The glass is broken by that boy.
玻璃杯是那个男孩打破的。
be有人称、数和时态的变化，其肯定式、否定式、疑问式的变化规则与be作为连系动词时完全一样。
如：English is widely spoken around the world.（肯定式）
English is not widely spoken around the world.（否定式）
Is English widely spoken around the world?（疑问式）
Yes,it is./No,it isn’t.
