Here are some questions and answers about exercise and diabetes.
How can exercise help my diabetes？
Exercise can help control your weight and lower your blood sugar level. It also lowers your risk of heart disease, a condition that is common in people who have diabetes. Exercise can also help you feel better about yourself and increase your overall health.
What kind of exercise should I do？
Talk to your doctor about what kind of exercise is right for you. The type of exercise you can do will depend on whether you have any other health problems. Most doctors recommend aerobic exercise, which makes you breathe more deeply and makes your heart work harder. Examples of aerobic exercise include walking, jogging, aerobic dance or bicycling. If you have problems with the nerves in your feet or legs, your doctor may want you to do a type of exercise that won't put stress on your feet. These exercises include swimming, bicycling, rowing or chair exercises.
No matter what kind of exercise you do, you should warm up before you start and cool down when you're done. To warm up, spend 5 to 10 minutes doing a low-intensity exercise such as walking. Then gently stretch for another 5 to 10 minutes. Repeat these steps after exercising to cool down.
When you start an exercise program, go slowly. Gradually increase the intensity and length of your workout as you get more fit. Talk to your doctor for specific advice.
Are there any risks to exercising for people with diabetes？
Yes, but the benefits far outweigh the risks. Exercise changes the way your body reacts to insulin (胰岛素). Regular exercise makes your body more sensitive to insulin, and your blood sugar level may get too low — called hypoglycemia (血糖过少) —after exercising. You may need to check your blood sugar level before and after exercising. Your doctor can tell you what your blood sugar level should be before and after exercise.
If your blood sugar level is too low or too high right before you plan to exercise, it's better to wait until the level improves. It is especially important to watch your blood sugar level if you exercise in really hot or cold conditions, because the temperature changes how your body absorbs insulin.
How will I know if my blood sugar is too low while I'm exercising？
Hypoglycemia usually occurs gradually, so you need to pay attention to how you're feeling during exercise. You may feel a change in your heartbeat, suddenly sweat more, feel shaky or anxious, or feel hungry. When you feel this way, you should stop exercising and follow your doctor's advice about how to treat hypoglycemia. Your doctor may suggest you keep candy or juice on hand to treat hypoglycemia.
What else should I do to exercise properly？
Many people with diabetes have problems with the nerves in their feet and legs, sometimes without even knowing it. So it's important that you wear shoes that fit well and have plenty of room when you exercise. Otherwise you could develop blisters or other sores on your feet that can lead to infection and other problems. You should check your feet before and after you exercise to make sure them are no blisters or other sores.
Should I drink more fluids during exercise？
Yes. When you're exercising, your body uses more fluid to keep you cool. By the time you feel thirsty, you may already be getting dehydrated. Dehydration (not enough fluid in your body) can affect your blood sugar level. Drink plenty of fluid before, during and after exercise.

Through my mom's loving words, I found a way back.
When you wake up in jail —especially having been raised by God-fearing, hard-working, honest people like my mama and daddy —you know what alone means. You've betrayed who you are, the values you believe in, and the people Who gave you everything. At that moment, being a country singer wasn't what mattered. All I could think about was what I was going to tell the Pentecostal (对灵降临节派的) preacher's daughter who brought me up.
I woke up on March 15, 2001, on a tiny cot in a jail cell in Nashville, wondering how it all came to this. At 37, I was looking at a sentence of 15 years for felony theft, and by all rights, I should have served it. I was addicted to crystal methamphetamine (冰毒), and I'd been stealing my friends' musical instruments and pawning (典当) them to get money to feed my habit. I'd been caught red-handed (当场) with ＄25,000 worth of pilfered (偷窃) equipment stacked up in my living room. And I was high as a Georgia pine.
Never in a million years did I think I'd end up behind bars. I'd had a rocky start in life, and the meth made me feel as if I was on top of the world. It beat back all the self-hatred I'd felt for a very long time.
I was given away when I was three months old. I was born in Alabama, but Barbara and Ed Bates, who went on to have eight biological children, took me in —even though I had double pneumonia and cigarette burns on my diapers. They lived in Columbia, Miss., where Daddy was a sharecropper (佃农), and there wasn't a lot of money to go around. Mama did the best she could, but her idea of a child going to school looking neat was double-knit pants and slicked-down hair. I wore glasses, and to top it off, I was fat. I felt like a geck, and was treated like one too.
Then one day on the school bus, my cousin told me I was adopted. At the age of nine, I felt like an outsider in my own family. Mama tried to make it right. She said, "Out of all our kids, you're special, because we got to pick you. God just gave us the rest of these knotheads."
That was her way of letting me know I was really loved. But I always had a fear of abandonment, and wondered why my birth mother gave me away. When I was 30, I went looking and found her. She told me she wasn't positive who my real daddy was, which only reinforced my notion that I wasn't worth much.
But it also made me want to prove myself wrong. I was 11 the first time I picked up a guitar and 15 when I wrote my first song. My dream was to make it as a country singer; and I spent years playing in bars throughout the South. In my mid-30s I moved to Nashville.
After two years of hard work, I somehow managed to get a songwriting deal, and a record label was showing interest in me. Then my wife and I started having marital problems, and we moved to another state. The move was like driving the last nail in the coffin on my dream. It felt as if I'd given up on myself.
One day during a trip I made to Nashville, a friend offered me a hit of methamphetamine from a little pipe. I didn't know then that meth is our biggest drag problem in rural America —that it's the easiest, cheapest drug to obtain, and also one of the most addictive. So I smoked it. And that was all that I thought about for the next year and a half. I ended up with a one — to two —gram-a-day habit, at a hundred dollars a gram.
When the police arrested me, I looked like death, and didn't care. My body was so beat up from doing drugs that my eyes were sunk back in my head, and my teeth and hair were failing nut from malnourishment ([营养不良). The first seven days in jail, I just slept, goin
听力原文：W: I heard there was a scene at the dinner last night.
M: You're right. Nobody at the table could put up with Dr. Lawrence. He proposed that life would be much better in this country if we had a segregation policy.
Q: How did the other guests feel about Dr. Lawrence's suggestion？
