He had no connection with the outside world for half a year,

He had no connection with the outside world for half a year,(giving)him enough time to work on his novel.
"他与外界隔离半年,给自己足够的时间来创作小说."
个人认为,后半句的him最好改成himself.
因为主语是he,he give himself表示“他给自己.”
这里用ing的原因是,he和give的关系是主动的.所以用主动的现在分词表示伴随.原句子可以改成：
He had no connection with the outside world for half a year,and he give himself enough time to work on his novel.
