cover up

Cosmetics do not always cover up the deficiencies of nature.

化妆掩饰天生的缺陷。

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”就是打空洞的可持口号，实际干危害生态的勾当。

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，那样就说明他们不愚昧，没有干蠢事。
