丹尼斯自己不努力，还老是眼红别人的成就。

[误] Denis himself doesn't work hard； however, he is always red-eyed of other people's achievements.
[正] Denis himself doesn't work hard；however, he is always green-eyed of other people's achievements.

注：中国人说一个人嫉妒用“眼红”，但英美人则用“眼绿”来形容。英语的 green 除了表示颜色之外还有“嫉妒”的意思，又如：I was absolutely green (with envy) when I saw his splendid new car（我看到他那辆漂亮的新车非常眼红）。其实，英语中许多表示色彩的词汇都有特殊的含义，不能照字面去理解。再比如：He gave me a black look（他恶狠狠地蹬了我一眼）；She visits us once in a blue moon（她难得来看我们一次）等。
