Right now, most of the data available on people's changes in drinking behavior are limited to small surveys.

目前，人们饮酒行为变化的大部分数据都局限于小型调查。

They examined years of data gathered about the tea drinking behavior of almost 500,000 adults in Britain for as many as 14 years.

他们研究了多年来收集的有关英国近50万成年人长达14年的饮茶行为的数据。

But researchers have never studied the impact on drinking behavior of a catastrophe that lasted as long and was as pervasive as the current pandemic.

但研究人员从未研究过持续时间和波及范围堪比当前疫情的灾难对饮酒行为的影响。

So we know, for example, that people's drinking behavior is very much affected by the price of the alcohol.

所以我们知道，例如，人们的饮酒行为在很大程度上受酒精价格的影响。
