过去分词短语放在句首
分词放在句首是一个独立主格，表时间，原因，条件，伴随，而分词分两种，现在分词表进行，主动;过去分词表完成，被动
动名词放句首表一贯作某事
Injured during the football match,the boy was examined by a doctor翻过来是因为已经在足球比赛中被别人弄伤了，所以那个男孩被医生检查了。injured前面省略了being
Injuring during the football match,the boy was examined by a doctor表示那个男孩在比赛中自己受了伤，所以被医生检查
你理解错了，其实这两个句子中没有动名词放句首，都是分词，只不过一个表主动，一个表被动

如何分辨动名词和现在分词
ing形式动名词是被当做名词来用的，可以作主语宾语，像readingroom有点类似于两个名词并列构成一个新名词的用法，比如bookshelf，womenteacher之类ing形式的现在分词一般用在进行时，过去进行啦现在进行时啦，有的时候把它当非谓语动词用，大部分时候起着动词的作用。就像楼上所说sleeping=babyissleeping即便sleepingbaby中sleeping有点像定语，但还是有一个动作正在进行的意味。所充当的成分不同，一个名词，一个动词的变形，而且后者往往意味进行，这是两者较明显的区别
什么单词后面用动名词
1 放在句首的动词原形是祈使句型：比如（Please）Make sure you are not the last to get there.
2 放在句首的动名词做句子主语，它更多地表示名词词性，不再强调动词词性。
比如：Giving up on her is probably one of the most difficult decisiions I've ever made.
