被动语态由什么构成

  被动语态没有宾语。如果把被动句变为主动语态，被动句中的主语就是主动句中的宾语。例如I ate an apple.其中apple是宾语，An apple was eaten by me.原句的宾语（apple）变成了主语（apple），所以被动语态没有宾语。

  

一般将来时里的被动语态

  “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.

  被动：Several big modern power plants will be built in our city.

  我市将建立几座大型现代化的发电厂。

  （“shall do”中的“shall”要随新主语变为“will”，“do”要变为“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.

  过年九月我将送我次子去读书。

  主动：In order to fool people cheaps and swindlers will make such bricks out of lead covering the "lead brick" with gold.

  被动：Such bricks will be made out of lead covering the "lead brick" with gold by swindlers.

  砖块外面会被骗子们镀上一层金来做这样的“金砖”。

  主动：They will ask you a lot of strange questions.

  被动：You will be asked a lot of strange questions by them.

  他们将问你许多怪题。

  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 one”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 future.

  被动：More space explorations will be made in the future by the Chinese people.

  中国人民在未来将进行更多的太空探索。
