In England nobody1 under the age of eighteen is allowed2 to drink in a public3 bar4．
Mr． Thompson used5 to go to a bar near his house quite often，but he never took6 his son，Tom，because he was7 too young． Then when Tom had8 his eighteenth9 birthday， Mr．Thompson took him to his usual10 bar for the first time．They drank for half an hour， and then Mr．Thompson said11 to his son，Now， Tom，I want to teach you a useful12 lesson．You must always be careful not to drink too much． And how do you know when you've had enough？ Well， I'll tell you．Do you see those two lights at the end of the bar？ When they seem13 to have become four，you've had enough and should go home．
But， Dad， said Tom，I can only see one light at the end of the bar．
在英国，十八岁以下的人不准进夜店喝酒。
汤普森先生以前常常去他家附近的一个夜店喝酒，但他从来不带他的儿子汤姆去，由于他年龄太小。后来，当汤姆年满十八岁的时候，汤普森先生首次带他去他常去的那家夜店。他们喝了半个小时，而后，汤普森先生对他儿子说：汤姆，目前我要对你说一个有益的教训。你需要时时小心不要喝得太多。你如何了解你喝够了呢？好，我来对你说。你看见夜店那头有两盏灯吗？当那两盏灯看着变成四盏的时候，你就喝够了，应该回家了。
可是，父亲。汤姆说：在夜店那头我只能看见一盏灯。
