The first step in exercising for most people is determining whether or not they should. This is particularly true with anyone over thirty-five, especially if they have been heavy smokers. Likewise, young adults who have been very inactive should proceed slowly and with caution. A physical evaluation from a physician is recommended, preferably one that includes an exercise-stress test. While a person is exercising, a stress test detects cardiovascular problems that might not show up when the body is at rest. This is done by monitoring blood pressure, pulse rate, oxygen consumption, and the heart's electrical activity while exercising. Whatever exercise program is selected, it is important to start with warm-up periods. These should include stretching exercises, jumping jacks, or active walking. The idea is to increase heart rate and circulation slowly without placing a sudden strain on the heart or the muscles that are starting to work. The next phase in developing an exercise program is to determine the amount of exercise that is enough to condition the muscles and cardiovascular system without excessively exhausting the body. This involves taking one's pulse and finding one's target zone. This target zone, or safe-training pulse rate, is established by subtracting one's age from 220 and then taking 60 percent to 80 percent of that total. If you are just starting to exercise, 60 percent is recommended; 80 percent is recommended if you are already in good condition. The author writes the passage mainly to recommend _ . A) that heavy smokers should quit smoking for the sake of their health B) that we should do warm-up periods either before or after doing exercises C) that young adults should live an inactive life instead of doing exercises D) that we should take up physical exercises according to our physical condition

When your pet meets your infant ,it might not be love at first sniff. When Jennifer brought her baby home from the hospital, her cherished dogs had very different reactions. Her Boxer, Sonya, was immediately gentle and protective. But Tiger, the Pomeranian, was less welcoming. "If any diapers or toys were on the floor, he peed on them," says the Greenbrier, mom. In the eyes of a pet, there's a new star in home who's stealing his spotlight. Even the gentlest animal will probably act up if he doesn't get his usual attention. These simple steps will help your pet adjust and keep your baby safe. Introduce Them with Care Your newborn and per's first encounter can set the tone for their relationship. To make it as smooth as possible, try this trick from Caryn Ruiz:"Before we left the hospital, my husband took blankets home to our dog, Daisy, so she'd know our newborn Devon's smell." When you get home, have your husband carry the baby so you can greet your pet without worrying about her jumping on you. A cat will likely walk away at first, while a dog probably wants to investigate right away. To introduce your baby, get down on your pet's level and let her have a hello sniff. Don't panic and pull your baby away unless your pet is barking or hissing, because it'll send the message that the baby is a threat. Learn the Safety Basics No matter how smoothly the introduction goes, there are certain safety rules you should follow. Never leave your baby alone with the pet. Even the gentlest animal can react unpredictably. Your baby's crying could frighten your cat, or your dog could suddenly become territorial. Consider setting up baby gates to limit your pet's access. To keep your cat from jumping into the bassinet , try putting mosquito netting over the top. Cats hate sticky paws, so keep the crib and changing table off-limits by lining the edges with sticky strips made for furniture. You can also train your dog to sleep in a crate . What can we infer from the passage? A) Cats are more welcoming than dogs when they meet a newborn baby. B) You must show your baby to your pet dog when it is barking. C) You should never keep a baby together with your pet. D) The first introduction of your newborn baby to your pet is important.

Q: Make Up Your Mind to Succeed Kind-hearted parents have unknowingly left their children defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and performance were played down because "everyone's winner." And their report cards sounded more positive than ever before. As a result, Stanford University professor Carol Dweck, PhD, calls them "the overpraised generation." Dweck has been studying how people deal with failure for 40 years. Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it. Here's how they work: A fixed mind-set is grounded in the belief that talent is genetic - you're a born artist, point guard, or numbers person. The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame. When things get difficult, it's quick to blame, lie, and even stay away from future difficulties. On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego isn't on the line as much, the growth mind-set sees failure as a chance rather than shame. When faced with a difficulty, it's quick to rethink, change and try again. In fact, it enjoys this experience. We are all born with growth mind-sets. (Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise. Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure. What should parents do for their children based on Dweck's study? A) Encourage them to learn from failures. B) Prevent them from making mistakes. C) Guide them in doing little things. D) Help them grow with praise.

*Question*
"Last week," Dr. P said "I was invited to a doctors' meeting at the R. Hospital. In one of the rooms a patient, an old man, got up from his bed and moved slowly towards me. I could see that he hadn't long to live, but he came up to me and placed his right foot close to mine on the floor." "Frank!" I cried with surprise. He couldn't answer as I knew, but he tried to smile, all the time keeping his foot close to mine. My thoughts raced back more than thirty years--to the dark days of 1941, when I was a student in London. The scene was an air-raid shelter , in which I and about a hundred other people slept every night. Among them were Mrs. West and her son Frank, who lived nearby. Sharing wartime problems, we got to know each other very well. Frank interested me because he was not normal . He had never been normal, ever since he was born. His mother told me he was 37 then, but he had less of a mind than a baby has. Mrs. West, then about 75, was a strong, able woman, as she had to be of course, because Frank depended on her completely. He needed all the attention of a baby. One night a policeman came into our shelter and told Mrs. West that her house had been all destroyed. That wasn't quite true, because the West went on living there for quite some time. But they certainly lost nearly everything they owned. When that kind of thing happened, the rest of us helped the unlucky ones. So before we separated that morning, I stood beside Frank and measured my right foot against his. They were about the same size. That night, then, I took a spare pair of shoes to the shelter for Frank. As soon as he saw me, he came running--and placed his right foot against mine. After that, he always greeted me in the same way. The unlucky ones mentioned by the doctor were _ . A) those who suffered from illness. B) those who were killed during the war C) those who slept in the air-raid shelter. D) those whose homes were destroyed in air-raids
