同学你好~
Though Alfred Bloggs had gotten married long, his wife did not know his job.
had gotten married long可以改成had been married long, know可以改成know about知道，了解

Because he thought that dustmen were a low job.
because一般引导从句用，这句话可以改成：He hid the truth because he didn't think cleaning was a decent job. 他隐瞒了真相是因为他觉得清洁工不是体面的工作。

Every morning, he was dressed in a smart black suit leaving home, and then changed into overalls spending the day as a dustman.
he left home in a smart black suit可以这么说

It was not much work for him as a dustman. 这句话意思是多余的，表达也不够自然，可以去掉。

Meanwhile, they were remembering the happiness they had been gotten.
可以改成they were reminiscing about the happy time together.

In this way去掉，可以改成Soon
