Just as pavlov taught his dogs to salivate at the sound of a bell , you can teach someone to lubricate or become erect at the sight of a whip .
正如巴甫洛夫教会他的狗儿们在铃响时分泌唾液一样，你也可以教会某人一看到鞭子就兴奋得勃起。
Acid : acid from the grape plays a big role in old world wines , which tend to carry a tart zing that literally makes you salivate ( this is why a lot of sour wines are seen as appetite-openers ) .
