___ hard he tried ,he could not lift it .
A Whichever
B No matter
C However
D Although
为什么不选BD，选C呢 BD哪错了？

Answer 1

这是表让步的。
However hard he tried =No matter how hard he tried 表程度， 要用how 修饰hard

无论他怎样努力， 就是没法把那东西举起来

追问

however和no matter how在引导让步状从时有什么区别？

追答

引导状语从句没区别
但引导名词性从句时只能用 however

追问

那请您看下这个题
____,he often helps me with my study
A however he is busy
B however busy is he
C no matter he is busy
D no matter how busy he is
为什么答案是D？ABC哪错了？no matter how不就等于however么？

追答

等于呀， 问题是B 选项中它用了倒装， 而A 中however 没直接接所修饰的busy
C 中No matter 没有修饰busy 的how, 表意不清楚， 结构残缺

No matter how busy he is =However busy he is

追问

no matter how he is busy不对吗？No matter how busy he is应该也使用部分倒装了吧？

追答

no matter how he is busy不对， how 是修饰busy的， 应该紧跟busy
倒装指的是主语和谓语的位置关系， 如果谓语置于主语前那才算倒装， busy这个表语置于主语前，只是【表语前置】

Answer 2

B少了how, D 表示转折关系。句中没有转折关系，所以错啦。

Answer 3

C However 无论多么。。 整句翻译，无论他多努力，都不能把它抬起来。

B No matter ，应该是 No matter how hard he tried ,he could not lift it .缺少how一词。所以不选B
.
D although 的语序不对，应该说 Although he tried very hard ,he could not lift it . 所以D也不对。
