上课没听懂，这是老师给的例句，希望大家帮忙讲解一下这类题该怎么做？以上5道题该怎么写？

Answer 1

1.French is used as their first language by some Canadians.
2.English is spoke as the first language in New Zealand.
3.German is studied as the girl's foreign language.
4.Kinves are used for cutting things.
5.A big mirror is put behind all lights.
主动改被动的一半规则就是：把动词后面的宾语变为被动语态的主语，动词要改为被动形式，原句子的主语有时可以省略，如不省略则在原主语前面加个by，也就是宾语＋被动形式动词＋by＋主语,这样说能明白吗？

当年自己学的时候也一头雾水，别急，多看看就明白了。
被动句就是把主动句的宾语变主语，原主动句主语前面加个by，相当于中文中的被字句。谓语的变化：如果主动句的宾语是复数，则谓语的be动词就用are或were，如果是单数，则用is或was。主动句的动词变化为被动式便可。多练习，你一定能很快掌握的。
A 动词 B 转变为 B is/was/are/were 动词被动式 by A
