被动语态的口诀：一般现、过用be +V.过去分词，be有人称、时、数变。
完成时态have(has) done，被动将been加中间。
一般将来shall (will) do，被动变do为be done。
将来进行无被动，shall (will) be doing,现在完成进行同，have (has) been doing。
现、过进行be doing, 被动be加being done。
情、助、有、是妥安排，一律随新主语变。
否定助后加not，疑问一助置主前。
主语恰是疑问词，直陈语序主在前。
一般情助加be done，双宾多将间宾变。
复合宾语宾变主，宾补、主补相应变。

"情助"是指情态动词和助动词must，may，can，shall，will等一律随新主语(多是主动句中的宾语)来变化。
"疑问一助置主前"是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。
下面详细举例说明之。
一般现、过用be done, be有人称、时、数变例：1、主动：The children gave the foreign guests a warm welcome.被动：The foreign guests were given a warm welcome by the children.2、主动：People regard him as brilliant.被动：He is regarded as brilliant by people.以上两例都是一般时态用be done的例子，be有人称、时、数变，第三人称fo reign friends是复数，时态一般过去时，所以"be done"就是were given，而People reg ard him as brilliant一句，被动后的"be done"就变成单数第三人称is regarded的形式了。
被动：This speech was delivered by comrade Wang. (was delivered即一般过去时的被动态)完成时态have done，被动将been加中间。
(过去完成时had done也包括在内)。
例：1、主动：We have studied English for 3 years and on at the spare-ti me school.被动：English has been studied for 3 years by us and on at the spare-ti me school. (have随新主语变为has)过去完成时也是一样：主动: Somebody had cleaned my shoes.被动: My shoes had been cleaned by somebody.一般将来shall (will) do，被动变do为be done即由shall do或will do变为shall done或will be done。
例：主动: We shall build several big modern power plants in our city ne xt year.被动：Several big modern power plants will be built in our city next ye ar.(shall do中的shall要随新主语变为will, do为be done.)主动：I shall send my second boy to school next September.被动：My second boy will be sent to school next September.被动句中的by引出的宾语，一般说来，如果是人称代词你、我、他等，均可省略，someone no on e不由by来引出。
如果是名词不能省略，但当今英语也都可省略了。
主动：The Chinese people will make more space explorations in the futur e.被动：More space explorations will be made in the future by the Chinese people.但如果是一般过去将来时如何处理呢？请记下面口诀：一般过去将来时，过去某时将发生。
主动should (would) do，被动be done代原形。
将来进行无被动，现在完成进行同。
主动：A few days ago we were still not quite sure whether we should car ry out the new plan ahead of time.被动：...whether the new plan would be carried out ahead of time.将来进行无被动，shall (will) be doing,现在完成进行同．have (has) been doing,即将来进行时表示动作在将来某一时刻或某个阶段正在进行'现在完成进行时表示某-行为发生在过去．延续到现在，可能还要延续下去。
两种时态则不用被动语态。
现、过进行be doing，被动be加being done即现在进行时或过去进行时都是be的人称、时和数的形式加doing。
而被动态则是be加上being done的形式，being是不变的。
现在进行时和过去进行时的被动态是被动态个的重点，容易搞错。
例如：主动：The workers are repairing the main building of the Northeast Engi neering Institute.被动：The main building of the Northeast Engineering Institute is being repaired by the workers.情、助、有、是妥安排，一律随新主语变。
带情态动词和助动词等的被动态如何处理比较复杂。
要随新的主语来变化，这些词如can, could；will, would; shall, should; may, might; must; ought to; need需要；have to不得不；be going to; to be to; used to; seem to; happen to等。
例如：主动: We must keep this in mind.被动：This must be kept in mind.主动句变为被动句所遵循的4个步骤：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。
不用被动语态的情况1) 不及物动词或动词短语无被动语态（即多数的瞬间动词）：appear, die(死亡),disappear（消失）, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, standbreak out, come true, fall asleep, keep silence, lose heart, take plac e.After the fire, very little remained of my house.比较： rise, fall, happen是不及物动词；raise, seat是及物动词。
(错)The price has been risen.(对) The price has risen.(错) The accident was happened last week.(对) The accident happened last week.(错) The price has raised.(对) The price has been raised.要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。
特别是一词多义的动词往往有两种用法。
解决这一问题唯有在学习过程中多留意积累。
2) 不能用于被动语态的及物动词或动词短语：fit, have, hold, marry, own, wish, cost, notice, watch agree with, arri ve at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong toThis key just fits the lock.3) 系动词无被动语态（keep除外）：appear, be become, fall, feel, get, grow, look, remain, seem, smell, so und, stay, taste, turnIt sounds good.4) 带同源宾语的及物动词，反身代词，相互代词，不能用于被动语态：die, death, dream, live, lifeShe dreamed a bad dream last night.5) 当宾语是不定式时，很少用于被动语态。
