肋 (lèi): (bound form) rib

学习的过程中就受了点伤，裂了两条肋骨。

xué xí de guò chéng zhōng jiù shòu le diǎn shāng , liè le liǎng tiáo lèi gǔ .

I sustained a minor injury while studying—I cracked two ribs.

刚开始我觉得这功能有点鸡肋。

gāng kāi shǐ wǒ jué dé zhè gōng néng yǒu diǎn jī lèi .

At first, I thought this feature was a bit useless.

鸡肋、没必要加价 大屏娱乐、联网影音、语音控制 。

jī lèi , méi bì yào jiā jià dà píng yú lè , lián wǎng yǐng yīn , yǔ yīn kòng zhì .

A waste of money; no need to pay extra. Large-screen entertainment, streaming media, and voice control.

谁能将自身优势精准打在对手软肋上、牢牢守住防守底线，谁就能掌握比赛主动。

shéi néng jiāng zì shēn yōu shì jīng zhǔn dǎ zài duì shǒu ruǎn lèi shàng , láo láo shǒu zhù fáng shǒu dǐ xiàn , shéi jiù néng zhǎng wò bǐ sài zhǔ dòng .

Whoever can precisely exploit their opponent’s weaknesses with their own strengths and firmly hold their defensive line will take control of the game.

这其实暴露了所有地震预警系统的软肋：速度和精度都是此消彼长、矛和盾的关系。

zhè qí shí bào lù le suǒ yǒu dì zhèn yù jǐng xì tǒng de ruǎn lèi : sù dù hé jīng dù dōu shì cǐ xiāo bǐ cháng , máo hé dùn de guān xì .

This actually exposes the Achilles' heel of all earthquake early-warning systems: speed and accuracy are in a trade-off relationship, much like a sword and a shield.
