每日一练16(建议用时:25分钟)Ⅰ.阅读理解ABehind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when we finally clean up our act.If the evidence for how wrong the first idea is isn’t apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.The heartening conclusion is that the body has an amazing ability to heal itself if the damage is not too great.The effects of some bad habits—smoking, in particular—can haunt you for decades. But the damage from other habits can be largely healed.“Any time you improve your behavior and make lifestyle changes, they make a difference from that point on, ”says Dr Jeffey Koplan.“Maybe not right away. It’s like slamming on the brakes. You do need a certain distance.”But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research which concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month: The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won’t cure all that bothers you, of course. But doctors believe that many chronic diseases—from high blood pressure to heart disease and even some cancers—can be warded off with a few sensible changes in lifestyle.Not sure where to start? Surprisingly, it doesn’t matter, since one positive change usua lly leads to another. Make enough changes, and you’ll discover you’ve adopted a new way of life.1.

Your large family are looking at youbecause it’s your turn to open a present. You try to make a response that will seem both grateful and genuine. Instead, it comes across as awkward—even when you really like the present.According to the study by Professor Stefan Hofmann and Professor Mark Leary, this is a sign of ordinary social anxiety. Let’s explain some of the reasons why opening presents in front of others can make the gift opener so anxious.Some people just don’t like being the center of attention.“Being the focus of everyone’s attention puts pressure on people to be ‘perfect’ or follow social norms(规范). Everyone is more on their guard when lots of other people are watching,” Leary sai d.And it feels like your reaction is being judged by the other people in the room.“It is not only the act of opening a present but also the emotional response that other people are carefully judging to determine whether the person li kes the gift, ” Hofmann sai d. “This person is expected to be joyful and surprised. ”“People want to be seen as appreciative, but one always runs the risk of not conveying the appropriate level of appreciation, ” Leary sai d. “People may worry that they won’t respond as the gift giver hopes.”Both experts agreed that feeling anxious in this type of social situation was totally normal.“If we never experienced social anxiety, we’d deal with many social encounters(遭遇) in ways that go against social norms, make bad impressions on others, or even hurt other people, ” Leary explaine d.“Try to be in the present moment and enjoy the occasion, ” Hofmann recommende d. “Receiving and giving gifts is a human tradition that shows kindness. Worrying about what other people think or what impression I make on others detracts(减损价值) from this experience.”5. How does the gift opener feel if he hates opening gifts in front of others?A.
