He was laughed at by all people.They make the bikes in the factory. The bikes are made by them in the factory.He cut down a tree. A tree was cut down by him.（五）含有情态动词的被动语态We can repair this watch in two days.This watch can be repaired in two days.They should do it at once.It should be done at once.（六）特殊情况1.He made the boy work for two hours yesterday.The boy was made to work by him for two hours yesterday.2.Mother never lets me watch TV .I am never let to watch TV by mother.3.Jack gave Peter a Christmas present just now.（1）A Christmas present was given to Peter by Jack just now.（2）Peter was given a Christmas present by Jack just now.常见的句型结构：It is(was)agreed(believed/decided/hoped/thought.）that.大家同意（相信、决定、希望、认为）.It is(was)well known that.众所周知It is(was)taken for granted that.被视为当然It must be remembered that.务必记住.It mustnt be forgotten that.千万别忘记.It is(was)said(reported，heard，told，suggested)that.据说(报道、听说、告知、建议.)二、典型例题（ ）1The Olympic Games _every four years.A are held B were held Care holding Dwill ho1d（ ）2.
