We need to take action now.被动式是怎样的?We need to take action now.中形容action的被动式是怎样的?是：Action needed to be taken 还是Action needed to take?or Action needing to be taken?这个句子换成被动语态是什么?是action need to be taken by us now吗xutsiang的答案和另二位不一样.如果need to作为情态动词,那xutsiang答案是正确.比如:we hv to cut hair right now.变为hair hv to be cut right now.究竟如何?

你的回答是对的action need to be taken by us now.

被动语态形式是:助动词be＋及物动词的过去分词.主语是谓语动词动作的承受者.
把We need to take action now.这句话变成被动语态,把承受者action变为主语,把谓语变成被动形式needed to be,动词变为过去分词形式taken,最后把主语放在by后变成宾语,故Action needed to be taken by us.
1)把主动语态的宾语变为被动语态的主语。
(2)把谓语变成被动结构(be＋过去分词)
(根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。
(3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。

1.Action needs to be taken by us now.这是正确的转换方式. 2.Action needs to take.take不是感官动词,不能在不定式的后面直接接它的动词原形.3.Action needing to be taken.这是一个没有谓语动词的错误句子.这道题...

Action needs to be taken by us.
need作为一个比较特殊的情态动词,这里当成实义动词来使用.
变成被动语态时,情态动词是不用被动的.所以那个needed行不通.
这样,action做主语,就要把行为发出者发出的动词作为被动.
Action needs to be taken by us.
