一个英语句子结构的分析,
Thinking he was having trouble getting our son to fall asleep,这是前半句,后半句一会补充,否则提交不上来
后面句：（注意，这个句子前面是逗号）I walked quietly to the baby’s room and looked into the dimly-lit（灯光暗淡的）room.
1、分析句子结构，解释一下thinking怎么回事，开头就是非谓语动词？有些晕。
2、请标准翻译本句。

Answer 1

Thinking he was having trouble getting our son to fall asleep, 现在分词短语做原因状语
I walked quietly to the baby’s room and looked into the dimly-lit（灯光暗淡的）room.

=Because I thought he was having trouble (in) getting our son to fall asleep, I walked quietly to the baby’s room and looked into the dimly-lit（灯光暗淡的）room.
