use plain language meaning in English

是进一步提高

I will do my best to use plain language in discussing what is inevitably a rather technical subject
我会尽可能用浅白易明的文字来讨论这个技术性课题。
You can follow main ideas , key words and important details in a short text using plain language , can read printed or legible hand written notes , memos , or letters and can get new information about familiar topics from reading factual texts
你要可以用基本的语言跟住主题，重要词汇和重要陈述，可以看懂复印和简易的手写笔记，备忘录，或者信件。
