You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?
Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延遲發(fā)作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.
Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:
* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.
* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (彈性的) so they will stretch well.
* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.
If you are already feeling muscles soreness, here are some ways to help relieve it.
* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.
* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒緩) effect.
* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物質(zhì)) from them and ease the soreness.
* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.

A small dog should be belly-up after eating a handful M＆M’s, at least according to conventional wisdom. But watching “Moose”, a friend’s five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs?
Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate — it can poison them and in some cases is fatal. Chocolate’s danger to dogs depends on its quality.
Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines（一種衍生物）. This class of substances includes caffeine and the related chemical theobromine(可可堿). Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog’s heart to race up to twice its normal rate, and some dogs may run around as if “they drank a gallon of espresso,” according to Hackett.
Dogs are capable of handling some chocolate, but it depends on the animal’s weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs.
Around every confection-centered holiday — Valentine’s Day, Easter and Christmas — at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate’s heart-racing effect.
1. The underlined expression “belly-up” probably means______.
A. dead            B. poisonous                 C. running around  D. having a headache
2. All of the following are true EXCEPT______.
A. chocolate’s danger to dogs depends on its quantity and quality
B. people buy lots of chocolate around Valentine’s Day
C. an ounce of unsweetened baking chocolate is safe for Moose
D. there must be some theobromine or caffeine in espresso
3. What can we learn about Hackett?
A. He is an animal doctor.         B. He is a pet shop owner.
C. He is the owner of Moose       D. He is a doctor in a small hospital.
4. It can be inferred from the passage that Hackett believes that__________.
A. chocolate is truly deadly to dogs 
B. it’s OK to give chocolate to a big dog
C. pets are usually ignored around confection-centered holidays
D. a healthy dog probably could survive a chocolate poisoning
5. The passage is mainly about__________.
A. the poisoning of Moose   
B. the compounds of different chocolates
C. a handful M＆M’s chocolate is poisonous
D. the relation between methylxanthines and chocolate poisoning

One cold morning in winter, when I was a little boy, a smiling man with an ax on his shoulder stopped me, saying: “My pretty boy, has your father a grindstone（砂輪）”

The memory of turning the grindstone that winter morning sank into my mind． I have thought of it since． Now, whenever I hear words of flattery, I say to myself． “That man has an ax to grind．”

Lillian Hanson, a college student, expects to graduate in about two years. What makes Mrs. Hanson different from her classmates is her age-----73 years. She has been studying at college, a few courses at a time, for 27 years.
　　When Lillian Hanson graduated from high school, she went to the bank to borrow money for further education. The banker gave her no encouragement.

So Lillian Hanson went home and raised a family of nine children instead of going to college. Mrs. Hanson never forgot her dream of getting a higher education. When her children were grown, she tried again.
　　She finds that it is the hardest part of going back to school at her age to sit in class for long periods of time. Because she is not as quick as she used to be, Mrs. Hanson often gets up and walks around classes to keep from getting stiff(不靈活). At the beginning of a course in using the computer, the other students all stood up to give her a warm welcome when she introduced herself and explained why she was there and what her aims were.
