■ lose

一望而知是第四类动词。Lose something to somebody 是把什么东西输给了某个对手。

• We have lost many clients to our competitors.我们许多顾客输了给竞争者。
• We're losing our best teachers to industry.我们正在被工业抢去最好的教师。

但是，也可以说 lose something to something，后一个 something 是失去前一个 something 的原因，这个 to 是中国人不大习惯的。

• He'd lost his parents to an airliner crash at Chicago.他的父母在芝加哥的一次空难中丧生（这里仿佛“空难”是一个对手，自己在对抗中输了，父母输到了对手手中）。
• He has lost his hair and beard to chemotherapy.他因为化疗而头发胡须脱落。
• ... the number of jobs actually lost to outsourcing is small...(The New York Times, OP-ED, Nov. 27, 2007, A31)…真正由于外包而流失的工作机会，数目不大…
