don't be too hard on him; he is doing the job ___

问题描述:

don't be too hard on him; he is doing the job ___
A as best he can B best as he can
请问这里不是as best as he can 也对?
B 为什么错误 没此用法吗

don't be too hard on him 不要严厉对待他了
he is doing the job 《 as best he can》他已经尽他的努力做得最好了
倒装啊as在这里表示什么 什么用法2. [后接形容词或分词]被认为,被看作是,(从某种方式)与…对比时 A as best he can 表示他已经尽他的努力做的最好了,是说话的人认为的明白了吗?
