1、How many desks are bought by them every term?
这是一般现在时的被动语态：am、is、are + 过去分词（+ by sb.)
2、The young tree must be tied to the stick by us.
这是情态动词被动语态：情态动词+ be + 过去分词（+ by sb.)
3、You needn't do it now.It need not done by you now.(同样是情态动词的被动语态）
4、People use metal for making machies.Metal is used for making machies.(一般现在时被动语态)
(现在be used for (doing) sth.已经成为固定短语了）
5、He made me do that for him.I was made to do that for him.一般过去时的被动语态：was、were + 过去分词（+ by sb.）
注意：感官动词以及一些使役动词（如：have、make、let等）后面可以接宾语补足语是动词不定式的复合宾语（即宾语加宾语补足语）结构,主动语态中不定式不带to,但被动语态中不定式中的to不能省略.
6、Did they buld a birdge here a year ago?Was a bridge built here by them a year ago?
如果改为陈述句应该是：They built a bridge here a year ago.因为时间状语要放在地点状语之后.
