"好吃到流口水"英语怎么形容？
But meals were nicer; and as for sweets, I won't tell you how cheap and good they were, because it would only make your mouth water in vain.
不过，膳食要好一些；至于糖果嘛，我不想告诉你那有多便宜、多好吃，因为那只能使你白白地流口水。
--《纳尼亚传奇》
"流口水"-- make your mouth water, "白白地流口水"-- make your mouth water in vain.
我们来用这两个短语仿写几个句子：
The smell of the cooked fish made my mouth water.
做好的鱼那味道把我馋得直流口水。
Does it make your mouth water?
馋得口水都留出来了吧？
再来学习vain这个单词，它有"徒劳的，自负的，虚荣的"意思：
I think he is shallow, vain and untrustworthy.
我认为他浅薄虚荣，不可信任。
Police searched in vain for the missing gunman.
警方搜寻失踪的持枪歹徒，但毫无结果。
She closed her eyes tightly in a vain attempt to hold back the tears.
她紧紧地闭上眼睛，想忍住眼泪，但眼泪还是禁不住往下流。
All our efforts were in vain.
我们所有的努力都白费了。
Have you been taking my name in vain again?
你又在滥用我的名义吧？
Are you going to take the name of the Lord in vain when you do?
你这么做，打算让他们骂你吗?
