答案

参考答案:B

解析:心绞痛严重度分级(加拿大心血管学会):Ⅰ级:一般体力活动不受限,仅在强、快或长时间劳作时发生心绞痛。Ⅱ级:一般体力活动轻度受限。快步、饭后、寒冷或刮风中、精神应激或醒后数小时内步行或登楼、步行两个街区以上、登楼一层以上和爬山,均可引起心绞痛。该患者属于活动轻度受限,心功能诊断为Ⅱ级。Ⅲ级:一般体力活动明显受限,步行1~2个街区,登楼一层即可引起心绞痛。Ⅳ级:一切体力活动都可引起不适,静息时可发生心绞痛。

完形填空
When I was 17, I read a quote: “If you live each day as if it were your last, someday you’ll most certainly be right.” It made a(n)   36  on me,and since then,for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the   37  day of my life,would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to   38  something.
Remembering that I’ll be   39  soon is the most important tool to help me make the big choices in life,   40   almost everything—all expectations, all pride, all fear of embarrassment or failure—just falls away in the face of death,   41  only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to   42 . You are already naked.There is no reason not to follow your heart.
No one wants to die. Even people who want to go to   43  don’t want to die to get there. And yet death is the destination we all share. No one has ever   44  it, because Death is very likely to be the single best invention of Life. It clears out the old to   45  for the new. Right now the new is you, but someday not too long from now, you will   46  become the old and be cleared away.
Your time is   47 , so don’t waste it living someone else’s life. Don’t let the noise of other’s opinions drown out your own inner voice.Everything else is secondary.
