1 . One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.
In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.
The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do.
A.People may no longer hunt wild animals for their next meal. |
B.The physical demands of running affect our body in a beneficial way. |
C.Some people run to prevent disease, and others run because it makes them feel better. |
D.Runners were 27% less likely to die for any reason, compared with nonrunners. |
E.But researchers point out, to infer something like that, they need the whole population measured. |
F.But new research suggests people may be able to get life-lengthening benefits by running for far less time. |
G.The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying. |
2 . It’s 5:00 in the morning when the alarm(闹钟)rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I force my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is on my face. It’s not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my "no thank you", or by my choice to have a salad. Over the years, I have learned it’s okay to just say "no". I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self-confidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.
