英国一项统计显示，八分之一幼儿在不到3岁时就已出现蛀牙。牙医指出，引发这一问题的罪魁祸首就是果汁——200毫升有机苹果汁大约含20克糖，与可乐相当。

Tens of thousands of young children are suffering from tooth decay caused by drinking fruit juice and squash, a recent study has revealed.
As many as one in eight children have suffered tooth decay by the age of three — although in some parts of England, the rates are as high as a third.
Senior dentists say the problem is often caused by well-meaning parents giving toddlers sugar-laden drinks in bottles.
Some middle-class parents would buy expensive organic juices in the belief they are healthier, but dentists have warned they can contain as much sugar as a glass of coke.

最近一项研究显示，数以万计的儿童长蛀牙是由平时喝果汁和果汁饮料导致的。
在3岁儿童中，每8个人中就有1个患有蛀牙；在英国的某些地区，甚至每3个孩子中就有1个患有蛀牙。
一些资深牙医称，这个问题常常是由好心的父母造成的——他们为孩子购买瓶装的含糖饮料。
有些中产阶级家境不错的父母会给孩子买较贵的有机果汁，认为它们更健康，但牙医们已发出警告，称有机果汁与可乐的含糖量相当。

【讲解】

文中的tooth decay就是“蛀牙”的意思，其中tooth是“牙齿”的意思，其复数形式为teeth，常用的相关词组还有：false tooth（假牙）、brush teeth（刷牙）和baby teeth（乳牙）等。形容词dental意为“牙齿的”，“牙医”的英文是dentist，“牙痛”的英文是toothache。

此外，文中的well-meaning用作形容词，解释为“好心的、善意的”，相当于well-intended。
