They sill plant trees on the small hill next year变成被动语态是被动语态 

问题描述:

They sill plant trees on the small hill next year变成被动语态
是被动语态 

Trees will be planted on the small hill by them next year.
翻译:明年树将要“被”他们种在小山上.
They sill plant trees on the small hill next year.
翻译:明年他们将要“把”树种在小山上.
很明显的,和语文一样,把 “把字句”改为“被字句”就好
你自己做之前要用中文先翻译一下~
望采纳~~或赞同~~~谢谢~~

The trees still be planted by them on the small hill next year.

Trees will be planted on the small hill by them next year.
被动语态:be+done .
