被动语态的结构是什么？
1、肯定句：主语+be +过去分词+（by～）. 2、否定句：主语+be not +过去分词+（by～）. 3、一般疑问句：Be +主语+过去分词+（by～）？ 4、特殊疑问句：疑问词+be +主语+过去分词+（by～）？ 被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be动词后面的过去分词不变。 扩展资料： 变被动句步骤 1、把原主动句中的宾语变为被动句的主语 2、把动词变为被动形式即be +过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。 3、原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。 4、其它的成分（定语、状语）不变。 含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。初中阶段可用于被动语态的情态动词有“can、may、must、need、should”等，分别表示“能够被……”，“可以被……”，“必须被……”，“需要被……“，应该被……”等。
被动语态的结构是什么呢？
一、一般地讲，被动语态可用于英语的各种时态。为了能准确地运用被动语态，重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下：1、 一般现在时的被动语态. am / is / are + 动词的过去分词Our classroom is cleaned every day.This car is made in China.2、一般过去式的被动语态: was / were + 动词的过去分词His desk was cleaned just now.The station was built in 1928.3、现在进行时的被动语态: am / is / are + being + 动词的过去分词A new factory is being built in our city now.Some trees are being cut down in the park.4、过去进行时的被动语态: was / were + being + 动词的过去分词A new factory was being built in our city at that time.Some babies were being looked after by Miss Chen last year.5、一般将来时的被动语态:(A) will / shall + be + 动词的过去分词(B) am / is / are + going to be +动词的过去分词.Some new factories will be built in our city this year.Your watch is going to be mended in an hour.6、过去将来时的被动语态: (1).would / should + be + 动词的过去分词 (2).was / were +going to be + 动词的过去分词.She said that some new factories would be built soon in our city.He thought that your watch was going to be mended after an hour.7、现在完成时的被动语态:have / has + been + 动词的过去分词Some new factories have been built in the city since last year.Your watch has been mended already.8、过去完成时的被动语态:had + been + 动词的过去分词He said that some new factories had been built in the city.I didn’t know that my watch had been mended .9、含情态动词的被动式：can/may/must + be + done例如：He can not be found. / I must be paid for this.二、什么情况下要用被动语态呢？一般地说，有下面几种情况：（1） 不知道谁是动作的执行者或没有必要。例如：①Paper is made from wood.纸是由木材生产出来的。②The house is quite old. It was built in 1950.这座房子太旧了。它是1950年建成的。③He was wounded in the fight.他在战斗在受伤了。④Electricity is used to run machines.电是用来开动机器的。（2） 需要强调动作的对象时。例如：①Calculator can t be used in the maths exam.计算器不能用于数学考试。②Books and newspapers in the reading room mustnt be taken away.阅览室的书籍和报纸不准带走。③He was awarded first prize in that contest.他在比赛中获得了第一。（3）为了使语气婉转，避免提到是谁做的这件事。例如：The construction of the new lab must be completed by the end of next month.新实验室必须在下个月底前完工。三、被动语态的含义英语中时态很多，但语态不多，只有两种，即：主动语态和被动语态。所谓“被动语态”，相当于中文中常说的“被……”、“由……”的句式，如：“他的自行车被偷了。”，“这座楼房是由他们建造的。”
被动语态的八种基本结构
被动语态的八种基本结构如下： (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。
被动语态的结构是什么？
有以下7种句式： 1、一般现在时：主语+be（is/am/are）+过去分词+其它。 2、一般过去时：主语+be（was/were）+过去分词+其它。 3、一般将来时：主语+will+ be(不变形) +过去分词+其它。 4、现在进行时：主语+be(is/am/are)+being+过去分词+其它。 5、过去进行时：主语+be(was/were)+being+过去分词+其它。 6、现在完成时：主语+have/has+been +过去分词+其它。 7、过去完成时：主语+had+been+过去分词+其它。 扩展资料： 在英语中，被动语态使用得比汉语要多，要普遍，但大多数句子都使用主动语态。被动语态在英语中极为重要。许多课本及考试乃至实际应用中都常常涉及到这个问题。一般说来，当强调动作承受者，不必说出执行者或含糊不清的执行者时，多用被动语态。需要注意的是，许多地方与汉语不同。 注意：那些汉语中有“被……”的短语往往又不是被动语态，而是主系表结构。还有些特殊现象，如：“known to me的意思，英语却应该用被动态。还要注意，英语的被动语态往往由“by”引出，而有用介词“by on foot”步行（美国人有时用“by foot”），“in carriage”（乘四轮马车）等等。
