he didn not know what was happening outside为什么这里不用happened 我觉得应该是被动关系
楼主没有错的.楼主可以回忆下我们常常说的“发生了什么事?”是怎么说的呢,是“what is happen ”对吧,这就是上面你的例句后面的“what was happening outside”,只不过他是过去进行时,表示过去某时刻正在进行的动作,时态不同而已.
happen这个词确实与平常动词有些区别,他有几种用法,以下就替楼主扩展以下吧,以前我也常常搞错:
1.表示“某地(某时)发生了什么事”,常用“sth.+ happen +地点/时间”这一结构来表达,此时主语应是事情.例如:
The story happened in 2003.这个故事发生在2003年.
An accident happened in that street.那条街上发生了一起事故.
2.表示“某人出了某事(常指不好的事)”,要用“sth.+ happen+to sb.”这一结构来表达.例如:
A car accident happened to her this morning.今天上午她发生了交通事故.
What happened to you?你怎么啦?
3.表示“某人碰巧做某事”,要用“sb.+ happen+ to do sth.”这一结构来表达.例如:
I happened to meet a friend of mine in the street yesterday.昨天我碰巧在街上遇到了我的一个朋友
4.happen表示“碰巧或恰巧发生某事”时,还可用“It happens / happened that...”这一结构来表达.例如:
It happened that Brian and Peter were at home that day.碰巧那天布莱恩和彼得在家了.
It happened that he had to take part in a meeting that afternoon.碰巧那天下午他不得不参加一个会议.
:happen有过去式为happened,但它是不及物动词,没有被动语态,楼主说的被动关系的不正确的,这点注意.楼主也可以上网查查看happen有没有被动语态就知道了.

是过去正在进行,所以用was happening

因为你前面已经用了was,这里的时态应该是过去进行时,所以后面加加ing。

happen 是不及物动词,没有被动语态的,而且,“被发生”也不通啊。

happen没有被动
希望你翻翻语法书
这是一个特例

be动词后面应该是动词+ing。要么就是动词的被动语态。所以按句意理解。事情发生不被可能,所以要用happened。

happen 是没有被动的。这里用进行时是正确的。

He didn't know if he had passed the exam.这句话从语法上来讲对吗?didn't know 能与 if 句末需要加or He didn't know if he had passed the exam or not. i didn't know he __( not take)part in the match Not having been told ,he didn't know where to star.的翻译 _____her before,he didn`t know she was his aunt.A Not see B Not havingseen C Not saw D Having not see ______,Johnson didn't know how to begin.A.Not having made a speech beforeB.For he knew nothing about a speechC.He didn't know any speechD.Having not made any speech before he didn not know what was happening outside为什么这里不用happened 我觉得应该是被动关系 Not being familiar with Shanghai,he didn't know where to go.这是非谓语,但是为什么用being familia Although the work was not difficult,yet he didn't know how to do后要加It吗 语法:Not until Mr Smith came to China ___ what kind of a country she is.A.he didn't know B.he knew C.did he know D.he could know 英语翻译Dear There`re always some things that let me in tears.I know that you didn't tell me anything,so it's just my guess and also I am not sure whether it's right or not.please believe me,i really like you Sometimes I can't express exactly wha The man wasn't able to understand English.So he didn't know what I wanted.变成动词ing形式!我写的是:Not understanding English,he didn't know what I wanted. He didn't know how he could get here He said he didn't know it yet 怎么翻译 Because he didn't know how to do it,he went to her for help._____ _____how to do it,…….可否直接用Didn't know how to do it,…… .还是Not knowing how to…….Because he didn't know how to do it,he went to her for help.句型转化为 __ Not until Mr.Smith came to China_what kind of country she is.he knewhe didn't knowdid he knowhe couldn't know选出正确答案并给出理由 He didn't know _____ he should go or not.A.if B.weather C.that D.whether选什么?快 ____,he asked the teacher .为什么选BA.Not knew how to do B.
