I want to lose the extra fat on my body.

他已经不爱你了，你做什么对他来说也是多余的。

Tā yǐjīng bù ài nǐ le, nǐ zuò shénme duì tā láishuō yě shì duōyú de.

He doesn’t love you anymore; whatever you do is unnecessary to him.

这些书对我来说已经多余了，我可以送给你。

Zhèxiē shū duì wǒ láishuō yǐjīng duōyúle, wǒ kěyǐ sòng gěi nǐ.

These books are no longer needed by me, I can give them to you.
