动词不定式有两种，一种是带to的动词不定式，一种是不带to的动词不定式，后者即通常所谓的动词原形。
动词不定式在句子中不能单独作谓语，但可以作主语、表语、宾语、定语、状语、宾语补足语和主语补足语等。动词不定式有时式（一般式、完成式、进行式和完成进行式）和语态（主动语态和被动语态）的变化。它既有动词的性质，又有名词的性质。
在一种复合结构里，不定式可以作宾语补语，它与宾语有主谓关系，两者构成复合宾语。如：
I want you to be happy.
What decided him to give up the job?
When I use the word moral, please don't understand me to mean anything religious.
I'll leave you to attend the matter.
We would like you to have an opportunity to appreciate Chinese art.
有一些动词后面的宾语补语通常是to be，这样的动词有believe、consider、declare、find、imagine、know、prove、suppose、feel、think、understand等。
I know this to be a fact.
They all felt the plan to be unwise.
We believe her to be innocent.
I consider him to be too lazy.
有一些动词后面作宾语补语的动词不定式通常是不带to的，这类动词可以分为两类：一类是感觉动词，如feel、see、hear、watch、notice等，如：
I saw him come.
I heard her sing.
We felt the house shake.
另一类是某些使役动词，如make、let、have等，但是使役动词get后面作宾语补语的动词不定式要带上to，如：
Let him do it.
I would have you know that I am sick.
They made the boy go to bed early.
My brother got me to run errands for him.
在动词find与help之后，动词不定式带不带to都可以，如：
He was surprised to find the sheep (to) break fence at this season.
Help me (to) get him to bed.
He helped her lift the box.
He helped her to mount the bicycle.
在动词know后作宾语补语的动词不定式也可以不带to，如：
I never knew anything make such a difference.
Never have I known a man die of love, but I have known a disappointed lover lose weight.
但是上述动词转换为被动结构中，其后的动词不定式一般都要带上to，如：
He was seen to come.
The boy was made to go to bed early.
The car was at last gotten to start.
The comrades must be helped to preserve the style of plain living and hard struggle.
He was never known to tell a lie.
你给出的那句句子，he后面的助动词应该是was，而不是has，这是一句被动句，首先可以排除C和D，因为动词steal（与荷兰语stelen和德语stehlen同源）是不规则动词，它的过去分词不是stealed，而是stolen，同时“他”也不是“被偷了东西”，即不表示被动，由于在被动句里，作主语补语的动词不定式要带to，所以不选择A，而要选择B，这句话的意思是说：“有人看见他从商店里偷了东西。”希望我能帮助你解疑释惑。
