Although _______ in a pool family ,he tried his best to live a better life.

Being done 的用法涉及动名词（gerund）和现在分词（the present participle） 两种.动名词的被动式在句子中充当主语、宾语和表语等,其功能相当于名词或代词；现在分词的被动式在句子中充当状语、定语等.部分中学生由于概念不清,不知道其内涵,在使用being done 时常常出错,就其用法归纳如下：
1.动名词的被动式有两种：being +过去分词；having been +过去分词.“having been +过去分词”就是“being + 过去分词”的完成体.例如：
1) 每个人都喜欢得到赞美.
Everybody likes ____________.（Key:being praised）
2) 在班上被嘲笑使得他恼羞成怒.
___________in the class made him angry.(Key:Being laughed at)
3）我记得曾经听过这故事.
I remember ____________ the story.(Key:having been heard)
2.在need/want/require （需要）和be worth(值得）等词后面,动名词的主动形式表示被动意义.例如：
1) 这件事需要调查.
The matter requires __________.(Key:being looked into)
= The matter requires to be looked into.
2) 这本书值得一读.
The book is worth __________ .(Key:reading )
= The book is worthy of being read.
2.现在分词的被动式.
现在分词的被动式也有两种：being +过去分词（强调事情正在发生）,通常在句子中作定语和状语.having + been + 过去分词（强调事情已经发生）,通常在句子中作状语.例如：
1) 她正接受提问,感到有点紧张.
________to answer the question,she felt a little nervous.(Key:Being asked)
2) 这么好的机会给了你,你怎么能一点也不珍惜呢?
__________ such a good chance,how could you not value it at all?(Key:Having been given)
作定语时,“being +过去分词” 表示正在进行的动作；having been done 表示过去或已经完成的动作；to be done 表示将要发生的动作.例如：
3) 正在建造的房屋,完工后将用作我们的图书馆.
