B.不管我如何努力,我都不能记住长单词.
这是一句状语从句,而且是让步状语从句（以“尽管、无论、即使”等词为标志）.
-ever 表示“无论...”（比如：whatever 无论什么、wherever 无论哪里）,引导让步性状语从句.
这类词语可以等于“no matter+ n  ,如whatever=no matter what, wherever=no matter where .
however 是一个副词,表示“不管到什么程度；无论如何”,修饰hard.hard应该要紧跟在however后面,however hard 等于no matter how hard.但是前者可以引导让步性状语从句和名词性从句,后者只能引导让步性状语从句.
让步性状语从句中本身就带有点强调的意思在,无需借助did强调,排除A.
how并不能引导一个让步性状语从句,排除B
D表达法本身就有错误,应该是no  matter  how  hard I had tried.

一般来说，however和no matter how 都有时，however更正确一点
又因为how引导的从句，部分倒装，所以选B

译：无论我怎么努力，也记不住那些很长的话
先理解句子的大概意思，然后分析句子的成分
要不然就用排除法吧

答案是B我怎么觉得是A

无论我多么努力都无法记住长单词。。
直译就是NO MATTER HOW HARD I TRIED，NO MATTER HOW=HOWEVER
这个只有背例句啦。。没有思路的。。。╮(╯▽╰)╭

选D

however 是副词 修饰副词hard 表示程度 故 答案是 B
选项A 语序错
选项AD how 应该 直接修饰副词
