Question

    Life is to be enjoyed. There’s no point in giving up something you enjoy unless you get something back that’s even better. When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living. The latest studies show that when you exercise and eat right:

YOUR BRAIN receives more blood flow and oxygen, so you become smarter and think more clearly, have more energy, and need less sleep. Two studies showed that just walking for three hours per week for only three months caused so many new neurons (神经细胞) to grow that it actually increased the size of people’s brains!

YOUR FACE receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, chronic emotional stress and smoking reduce blood flow to your face so you age more quickly. Smoking accelerates aging because nicotine causes your arteries (动脉) to narrow down, which decreases blood flow to your face and makes it wrinkle earlier. This is why smokers look years older than they really are.

YOUR GENES change. In May, a study was published in the Proceedings of the National Academy of Sciences showing that changing your lifestyle changes your genes.

YOUR TELOMERES (染色体端粒) get longer. Telomeres are the ends of our chromosomes (染色体) that control how long we live. As telomeres become shorter, then cells age more quickly, thus shortening our lives.

Besides, one of the most interesting findings in the study was that the mothers’ awareness of stress was more important than what was really occurring in their lives. The researchers gave the women a questionnaire and asked them to rate on a three point scale how stressed they felt each day, and how out of control their lives felt to them. The women who were aware that they were under heavy stress had significantly shortened and damaged telomeres compared with those who felt more relaxed. On the contrary, some of the women who felt relaxed despite raising a disabled child had more normal appearing telomeres.

In other words, if you feel stressed, you are stressed; if you feel fine, you are fine.

【解析】

这是一篇说明文。文章讲述了，人们感觉好，生活就好，可以通过适当的锻炼、正确的饮食和愉快的心情来达到。

1.

细节理解题。由第一段中的“When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living.”（当人们吃得更健康，锻炼身体，戒烟，更好地管理压力时，他们会发现自己感觉好多了，这就重新构建了从害怕死亡到享受生活的原因。），可知①③⑥有助于延长寿命。故选A项。

2.

句意猜测题。由第三段中的“YOUR FACE receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive.”（你的脸接受更多的血流量，所以你的皮肤发光更多，皱纹更少。你看起来更年轻更有魅力。），可知皮肤发亮，皱纹少意味着皮肤健康，白里透红，your skin glows在此处意为“当你健康时，皮肤颜色看起来像粉红色”。故选C项。

3.

细节理解题。由第三段中的“Smoking accelerates aging because nicotine causes your arteries (动脉) to narrow down, which decreases blood flow to your face and makes it wrinkle earlier.”（吸烟会加速衰老，因为尼古丁会使你的动脉变窄，从而减少流向面部的血液流量，使面部皱纹提前出现。），可知是尼古丁会使你的动脉变窄，正确的锻炼和饮食不会让你这样，C项错误。故选C项。

4.

主旨大意题。由第一段中的“Life is to be enjoyed. There’s no point in giving up something you enjoy unless you get something back that’s even better. When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living.”（生活是值得享受的。放弃你喜欢的东西是没有意义的，除非你得到了更好的东西。当人们吃得更健康，锻炼身体，戒烟，更好地管理压力时，他们会发现自己感觉好多了，这就重新构建了从害怕死亡到享受生活的原因。）和最后一段中的“In other words, if you feel stressed, you are stressed; if you feel fine, you are fine.”（换句话说，如果你感到有压力，你就有压力；如果你感觉良好，你就很好。），可知文章主要讲人们感觉好，生活就好，可以通过适当的锻炼、正确的饮食和愉快的心情来达到，D项“感觉更好，寿命更长”符合文意。故选D项。
