Thank happyjyl for pointing out my errors.
I mean the words microstructure and macrostructure have the samiliar tone when they are spoken.so I don't know how to identify them in listening.

microstructure and macrostructure：These two words sound really very close. microstructure is a bit short and light, but macrostructure is a bit long and strong when you pronounce the "ai" . You need also to consider the context. microstructure is maily used in biotechnology such as in cell structure; macrostructure is mainly used in economy and political issues.

I did not use English for many years,but I started to study English again from last year, because I expected to get a good job with higher salary and better warefare.I'm looking forward to improving my English in both listening and speaking.
I had a chat with a foreigner one time, however, I couldn't identify whether he ment the word "macrostructure" or "microstructure". Therefor, I gave a wrong answer to his question,that made me very sorry.
After all,how do I differentiate these two words ?[/

How about we start from an American Idiom: out of sight, out of mind.
大家看如何翻译：
有人翻译为：眼不见、心不想；眼不见，心不烦 ；就是不在视线之内也就不在思想；眼不见为净；不见就忘；“盲痴” (‘the blind idiot’)；似'人不在了, 也没有任何权力可言了', '人走势微'吧(实在想不出汉语里很匹配的谚语), 也含'人走茶凉'之意 ；久违情疏；离开某人的视线，离开某人的思想），是指你不必对跟你没有意思的事情烦恼或担心；
“人走茶凉”或者“眼不见心不烦”什么的，我都不喜欢，我喜欢浪漫点的翻译“离久情疏”。
out
of sight, out of mind" into another language and back to English. The idiom comes back
as "the invisible idiot；“盲痴” (‘the blind idiot’)；
