如果我想请她去好的饭店吃饭，那么……不够。

Rúguǒ wǒ xiǎng qǐng tā qù hǎo de fàndiàn chīfàn, nàme……bùgòu.

If I want to invite her to a good restaurant to eat, then.. I don't have enough.

我觉得自己的汉语水平还不够高，所以每天都练习。

Wǒ juéde zìjǐ de Hànyǔ shuǐpíng hái búgòu gāo, suǒyǐ měitiān dōu liànxí.

I feel my Chinese level is still not high enough, so I practice every day.

天气这么冷，穿一件衣服不够，你再加一件吧。

Tiānqì zhème lěng, chuān yí jiàn yīfu búgòu, nǐ zài jiā yí jiàn ba.

It’s so cold; wearing just one piece of clothing isn’t enough, put on one more.
