cover up

Cosmetics do not always cover up the deficiencies of nature.

化妆品未掩饰天生的缺陷。

But Shell, No. 6 last year, also faces charges from environmental groups of greenwashing, or using shallow claims of sustainability to cover up eco-unfriendly operations.

但是去年排名第6的壳牌也面临来自环保组织“漂绿”的指控，“漂绿”就是打着空洞的可持口号，实际干着危害生态的勾当。

They didn't know the best way to cover up their fatuity is let me have a happy life .Then it could show they were not fatuous, they have not do jackassery.

他们不知道掩盖自己愚昧的最好方式是让泰洋愉快地工作学习生活着，因为那样就他们不愚昧，没有干蠢事。
