being+过去式是为什么啊?when is this year's festival being held?为什么要用being held?是被动语态吗?如果是被动语态可以直接when's this year's festival held?就可以了吧,为什么要+being啊?鄙人语法严重的差,所 When能用过去式吗,为什么? 在过去式后面全是原型么when was she born 为什么有2个过去式 when are you getting married?为什么marry用过去式啊还有一个句子,they will get married soon.为什么这里marry又是这种形式.,两个句子 when did he bear与when was he born为什么不能说成when was he born,有什么区别,为什么was是过去式,还能加过去分词 when my mom came in,i pretend A.to be reading B.to be read不好意思。打错。B选项是to read ..为什么要加BEING啊？ Pumas never attack a human being except( )cornered?选项：A they are B being C that they areD when they are.为什么不能是A或C? When did it start?为什么did用过去式? when i was ill,i lay in bed.省略i was 可不可以写成：when ill,i lay in bed.或者：being ill,i lay in bed.到底应该哪个,关键是为什么啊? the question being settled和the job finished,同是被动.为什么前者加being啊? might是may的过去式,可为什么you might also get a headache when you work work potatoes turn green when exposed to light.exposed是过去式还是过去分词 为什么要加d When will Crazy Hotel be finished?这句话是将来时,为什么还有finished?finished不是过去式吗? Where is it being held?是什么时态Where is it being held?这句话是什么时态啊?但是，为什么“举行”要用held，它可是hold的过去式阿？对了，它的译文是：它在哪里举行？（它的上一句话是：它将在星 when the stom abated这句话语法对吗?为什么abate要+d?是过去式吗?还是形容词?错别字是when the storm abated 英语过去式when,while和过去进行时、过去式怎么搭配出句子,为什么 since when do you guys know each other为什么不用过去式这什么这个地方不用过去式, It is being repaired by a friend of my father's中的is being是表示正在进行中的中吗?那为什么正在进行中又用过去式repaired呢?
