Question

【题目】 New research suggests that our DNA helps us to decide whether we prefer coffee or tea. Researchers from the University of Queensland in Australia studied how our genes（基因） influenced our tastes and why we like some tastes more than others.

Following the research, researchers believe they know why some of us prefer coffee while others like tea more. The researchers have found that people who like more bitter tastes are more likely to drink coffee.

The researchers say they find something strange in their research. People who are more sensitive（敏感的） to the bitter taste of caffeine are more likely to prefer coffee to tea. They were also more likely to drink more coffee than those who are not so sensitive to caffeine.

Researchers looked at the study on more than 400,000 men and women in the United Kingdom. They also looked at an Australian study that compared the tastes of 1,757 twins（双胞胎） with their siblings. The researchers say genes aren’t the only factors（因素） influencing people’s tastes. Other things like our changing environment, social factors or the influences of taking medicine can also turn us on or off coffee or tea.

The researchers said we can learn to like coffee. Dr Liang-Dar Hwang said, “Bitter taste is influenced not only by genetics, but also environmental factors. Even though humans naturally dislike bitterness, we can learn to like or enjoy bitter-tasting food after being influenced by environmental factors.”

【2】D

【3】A

【4】B

【解析】

这篇短文主要讲述了新的研究表明，DNA会影响我们的口味，基因并不是影响人们口味的唯一因素。其他的事情，比如我们不断变化的环境、社会因素或者吃药的影响。

【1】细节理解。根据文中The researchers have found that people who like more bitter tastes are more likely to drink coffee.可知，喜欢更苦口味的人喝咖啡的可能性更大。故选C。

【2】细节理解。根据文中People who are more sensitive（敏感的） to the bitter taste of caffeine are more likely to prefer coffee to tea.可知，第3段中提到的人更有可能感受到咖啡因的苦味。故选D。

【3】词句猜测。根据文中They also looked at an Australian study that compared the tastes of 1,757 twins（双胞胎）可知该研究比较了1757对双胞胎和他们的兄弟姐妹的口味。下文中siblings.的意思是“兄弟或姐妹”故选A。

【4】推理判断。根据文中Dr Liang-Dar Hwang said, “Bitter taste is influenced not only by genetics, but also environmental factors.可知，环境也能影响人。故选B。
