| According to the professor’s philosophy, the antidote to envy is one’s own work, always one’s own work: not thinking about it, not assessing it, but simply doing it. (A) one’s own work, always one’s own work: not thinking about it, not assessing it, but simply doing it (B) always work; because you don’t think about it or assess it, you just do it (C) always one’s own work: not thinking about or assessing it, but simply to do it (D) not to think or assess, but doing one’s own work（A） (E) neither to think about one’s own work nor to assess it, it is always simply doing it 搜索过了，好像都没有提到do后面直接加it的问题。记得在lzm或者by的书上看到do it永远错，只能do so，所以直接去掉a,b,c,e，剩下的d也不对，没有办法选了。 大家注意到这个问题没有？ |
