There struck me a sudden idea. 突然我有了一个主意。

=An idea suddenly struck me.

=An idea suddenly occurred to me.

句中为何要加上 sudden 这个形容词？难道不应该是用副词 suddenly 吗？

解答如下：

句子中单词strike的为下面的意思,sudden为形容词修饰后面的名词idea

(1)strike  vt突然想到，猛地意识到，一下子想起(想法或念头) 

(英文解释：If an idea or thought strikes you, it suddenly comes into your mind.）

A thought struck her. Was she jealous of her mother, then?. 

她猛地冒出一个念头：那么难道她在嫉妒母亲吗？

At this point, it suddenly struck me that I was wasting my time.  

在这一刻，我突然意识到自己是在浪费时间。

（It suddenly strike sb that sb do sth某人突然想到/意识到某人要做某事）

(2)occur vi（想法或主意）被想到，被想起，（某事）浮现于脑海中

(英文解释 If a thought or idea occurs to you, you suddenly think of it or realize it.）

It did not occur to me to check my insurance policy. 

我没有想到要核实我的保险单条款。

(It occur to sb to do sth某人想到要做某事）

It occurred to me that I could have the book sent to me. 

我想到可以让人把书寄给我。

（It suddenly occur to sb that sb do sth某人突然想到/意识到某人要做某事）

There struck me a sudden idea. 突然我有了一个主意。

句中为何要加上 sudden 这个形容词？难道不应该是用副词 suddenly 吗？

【答】本句用sudden 和suddenly 都正确。请比较：

There struck me a sudden idea.

There struck me an idea suddenly.

不过，sudden 是形容词，修饰名词idea 的，suddenly 是副词，修饰动词struck 的。它们强调的词语不同，角度也不同。

继续比较：

The stream takes a sudden bend to the east. 

The stream takes a bend to the east suddenly. 

小溪突然转向东流。

【注意】英语中一些动词的词义，是根据句子的语境或某个词语的需要，而确定的。比如，strike ，hit 这些词，本来没有“突然”之意，正是因为有了sudden 或suddenly，才赋予了“突然”之意。又如：

It occurred to me that he had forgot to take his umbrella.（occurred 本来是“发生”，在这个语境中含有“突然”之意。“事件、主意”，一般都是突然想起来的居多。）

I was reading a book when someone knocked at the door.（when引导的句子含有“突然”之意）

请问此句会是倒装句吗？A sudden idea struck me there.
