难得

难得nándé听到tīngdào了le那么nàme好hǎo的de句子jùzi。

It's rare to hear such good sentences.

我wǒ生平shēngpíng难得nándé做zuò了le一yī件jiàn好事hǎoshì…却是Quèshì没用méiyòng的de。

For once in my life I'm doing a good deed... And it is useless.

如果rúguǒ你nǐ不会bùhuì说shuō英语Yīngyǔ，你nǐ就jiù很hěn难nán得到dédào一个yī ge好hǎo的de职位zhíwèi。

You're much less likely to get a good position if you don't speak English.
