不定式和分词作状语的区别
1. 现在分词与过去分词作状语的区别.
现在分词（v-ing）与过去分词（V-ed或不规则）做状语的最主要区别在于
两者与所修饰的主语的主动与被动关系的区别.
1）现在分词作状语时,现在分词的动作就是句子主语的动作,它们之间的关系是主动关系.
He went out shutting the door behind him.
他出去后将门随手关上.
Not knowing what to do, he went to his parents for help. （同本题）
由于不知如何办是好,他去找父母帮忙.
2）过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的关系是被动关系.
Given more attention, the trees could have grown better.
如果对这些树多关心一些,它们本来会长得更好.
Faced with difficulties, we must try to overcome them.
在遇到困难的时候,我们必须设法克服.
2 动词不定式和分词作状语的区别
1)分词作状语一般表示伴随,而不定式常常表示目的.
They stood by the roadside talking about the plan．他们站在路边谈论着这个计划.(伴随)
They stood by the roadside to talk about the plan．他们站在路边为的是谈论这个计划.(目的)
2)分词作状语放在句子开头,除表示原因之外有时表示时间或条件.动词不定式作状语时,除了表示目的以外,还表示结果或原因.
Reading attentively,he forgot the time for lunch．
由于在专心读书,他忘了吃午饭的时间.(原因)
Reading carefully,he found something he had not known before．
他仔细读书时,发现了一些从前不知道的东西.(时间)
Reading carefully,you'll learn something new．
只要你仔细阅读,你会学到一些新的东西.(条件)
His family was too poor to support him．他的家庭太穷,不能维持他的生活.(结果)
The boy is not tall enough to reach the book shelf．这男孩个子不够高,手伸不到书架.(结果)
We are glad to hear the news．我们很高兴听到这消息.(原因)
To see him behaved in that way , I would think that he must have got something wrong with himself . 看到他这样的行为,我想他肯定有点不对劲.（注意时间上的不同）
根据上边的分析,你在对号入座,首先,本句话的主语是he,因为是他不知道,因此肯定是主动的排除4,排除1是因为时间不对,不定式是指将要发生的.
希望帮到你,如果还不懂,可以追问

选3
这是非谓语动词作原因状语，前后主语都是he,he与know是主谓关系，所以选3

第3题正确，否定词提前，省略主语，主语是人，而且是主动语态，所以谓语用ing修饰

3是正确答案

3,Not knowing

选3.意思是因为不知道什么时候出发，他去问他的队长。
not knowing 是现在分词，在此处作状语表原因。

正确答案是3,。
Not knowing , 是现在分词的一般式的否定式，when to start out (可补充完整: when he should start out) 是knowing 的宾语。
Not knowing when to start out是作原因状语，可改为As he didn't know when to start out.

3

Not knowing 是对的。这个句子只有一个主语，也只能只有一个谓语，前面的只能是非谓语，对于主语来说非谓语又是主动地，所以用ing的形式。

选3,Not knowing when to start out是一个现在分词短语，表示主动意义，knowing的逻辑主语就是he，整个现在分词短语用作原因状语，可以改写为一个原因状语从句：Because he didn't know when to start,其中的when to start out属于“疑问词+不定式”这一名词性结构，用作knowing这个现在分词的宾语，而not这个副词否...

when to start out,he went to ask his captain
1.Not to know 2,Don't know 3,Not knowing 4,Not known
主要请解释这句话的结构！
答：3
Not knowing when to start out, he went to ask his captain.
译：由于不知道何时出发，他去问他的队长。
析：逗号前面的是句子的状语，由非谓语动词短语担任。2.是祈使句谓语结构，排除。1.是不定式，放句首作目的状语，不合句意，排除1. 4.是过去分词短语，表示被动，而这里应是主动的，后面还有宾语呢，排除4.
句子成分分析：
状语：Not knowingk when to start out
主语：he
谓语：went to ask
宾语：his captain
（另一种细分法：谓语:went
状语 to ask his captain.)
分词短语分析：
not knowing 现在分词的否定主动式
when to start out 疑问不定式，作knowing的宾语

选3， 首先主句是he went to ask his captain，句子意思：由于不知道什么时候出发，他去问船长。然后，he和know之间是主动关系，用现在分词ing，如果是被动则用过去分词ed，not要加在分词前面

3,Not knowing
现在分词做状语。动词know 和逻辑主语he 是主动关系。所以是ing 形式
