cover up

Cosmetics do not always cover up the deficiencies of nature.

化妆品能掩饰天生缺陷。

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壳牌也面临来自环保组织“漂绿”指控，“漂绿”就是打着空洞可持续口号，实际干着危害生态勾当。
