Comparing “chúfēi” and “yàobúshì”

除非有新的证据出现，否则我们目前不会轻易改变原来的判断。

Chúfēi yǒu xīn de zhèngjù chūxiàn, fǒuzé wǒmen mùqián bú huì qīngyì gǎibiàn yuánlái de pànduàn.

Unless new evidence appears, we will not easily change the original judgment for now.

除非双方都愿意各退一步，不然这场争论很难真正结束。

Chúfēi shuāngfāng dōu yuànyì gè tuì yí bù, bùrán zhè chǎng zhēnglùn hěn nán zhēnzhèng jiéshù.

Unless both sides are willing to step back a little, this argument will be hard to truly end.

要不是你昨天及时提醒我，我今天肯定会把这件事完全忘掉。

Yàobúshì nǐ zuótiān jíshí tíxǐng wǒ, wǒ jīntiān kěndìng huì bǎ zhè jiàn shì wánquán wàng diào.

Without your timely reminder yesterday, I would have completely forgotten about it today.

要不是那场突如其来的变化，事情原本不至于发展到这么被动的局面。

Yàobúshì nà chǎng tūrúqílái de biànhuà, shìqing yuánběn bù zhìyú fāzhǎn dào zhème bèidòng de júmiàn.

If not for that sudden change, the situation would not have become so unfavorable.
