2014年考研英语2的翻译题目如下：
The human body has evolved to deal with a constant flow of threats to its health. Over millions of years, our ancestors had to cope with predators, harsh weather, and disease. Our bodies have developed various defense mechanisms to deal with these threats. However, in today's world, many of these threats have diminished, and our bodies are not as well-equipped to handle the modern environment.
The human immune system, for example, has evolved to protect us from pathogens. However, in the absence of frequent exposure to pathogens, our immune system may become less effective. Similarly, our bodies have adapted to store fat as a reserve for energy. In the past, when food was scarce, this adaptation was beneficial. Today, however, with abundant food available, excess fat can lead to health problems such as obesity and diabetes.
Another example is our sleep patterns. In the past, humans had to be alert and ready to respond to threats at any time. As a result, our bodies have developed a natural tendency to sleep during the night and be awake during the day. However, in today's sedentary lifestyle, many people struggle to maintain a regular sleep schedule. This can lead to sleep disorders and other health issues.
In conclusion, while our bodies have evolved to deal with a constant flow of threats, the modern environment presents new challenges that our ancestors never had to face. It is essential for us to adapt and find ways to mitigate the negative effects of these new challenges on our health.
