哪位英语大虾帮我解析下定语从句和被动语态啊,尽量用通俗的语言,课本上的我看不懂啊\(≧▽≦)/

定语从句就是修饰【名词】的句子.
I have a carpet which can fly 我有一张可以飞的地毯.【物】【which】可用that
he is a boy who can lift this stone .他是个能举起这石头的男孩.【人】【who】 可用that
其中【who can lift this stone】就叫定语从句,修饰名词【boy】的句子.who在这里就不用翻译,你直接看做he is a boy ,【他是个男孩】he can lift this stone【他能举起这石头】.合起来念就是了.
当然有很多,人就用who ,物就用which,人和物一起就用that ,that在很多情况可以用,你记住这些就行了.还有很多种,一时说不完吖.打字很累.你可以去找找相关资料,我这里只是简单的说它的定义.
被动语态就是什么什么被怎样了.通俗的说就是中文的“被”句.比如：
the tree was cut down .这树被砍倒了.
we cut down the tree . 我们把树砍倒了.
这就是中文的“被”和“把”句.仔细看看,被动语态一般要有be动词.如例句the tree was cut down .有be 动词【was】be动词后面要加分词【过去分词和现在分词】哦.那些要去背的.
下面是其他被动语态：
the cup was broken .杯子被打碎了.
the man was killed.这男的被杀死了.
my idea was chosen 我的点子被看中了.
【附】被动语态还可以在后面加by ……【被……】翻译为【被谁】或【被什么】.再看例句
the cup was broken by him 杯子被他打碎了.
the man was killed by this knife这男的被这把刀杀死的.
my idea was chosen by my boss我的点子被我老板看中了.
求采纳.
