David is in the habit of knitting his brows whenever he concentrates on a problem.此句子中whenever至最后那一部分是做什么成分的?

whenever he concentrates on a problem=no mtter when he concentrates on a problem 是个让步状语从句
很高兴为您解答,fightout为您答疑解惑
如果本题有什么不明白可以追问,
再问：可我的老师说那部分是表语从句。
再答： David （主语）is（系动词） in the habit of knitting his brows（介词短语作表语） whenever he concentrates on a problem（让步状语从句）这是主系表结构，但这显然不是表语从句，表语是介词短语
再问：我也是这样认为的，一定是老师讲错了！英雄所见略同^O^👍👍👍👍👍*^O^*
再答：也可能是听错了。
再问：不，她这样讲过后，我又问了她一次，她都是这样讲的，最后还说听不懂拉倒，反正她不管了。这就是大学的英语老师啊！
再答：：）
