Answer 1

1）He often sleeps with these windows ____A open B opening C to open D be opened
这里的open是形容词，表示打开的。with sth.+形容词表示使某物保持某种状态。
2）Can I have this window open at night?
have sth. done, 使某事被做。have sth.+形容词，可以理解为keep sth.+形容词。
3）The editor remarked that the article was well written.
句子是被动语态，文章写得很好，省略了写文章的人。可以加by somebody,指出作者。well为副词修饰动词。written为write的过去分词。
