Is it okay to keep exercising when you have a cold? What about the flu? With winter viruses going around, it's important to know how to alter your training if you do catch a germ or two. "The guidelines are pretty easy," says Dr Lorenzo Masci from the Alphington Sports Medicine Clinic. "Anything above the neck --- so if you've got a cold for example, a runny nose or a sore throat --- then you should probably cut down your exercise by half and do 50 percent of what you normally do." "If you've got anything below the neck, like muscle pain, joint pain or fever, you shouldn't really exercise at all until those general symptoms settle down," Lorenzo says. He points out that a cough would also fall into this more serious category. "For example, if anyone comes in with a fever and a runny nose, I'd tell them to stop exercising until the fever and the muscle ache settles. Then they can start their training again at 50 percent once all those symptoms settle, even if they've got a bit of a runny nose or a sore throat." "The reason we tell people to stop exercising is because if you exercise when you're unwell it can make the illness worse and prolong it." There is a second reason Lorenzo advises his patients to stop exercising when they have "below the neck" symptoms. In the event you have an illness which affects your heart, exercise can sometimes actually lead to death. Lorenzo advises to take zinc and vitamin C as a way of preventing colds. But he admits that this is controversial --- some studies have shown that these supplements can improve immune function while other studies have cast doubt on the issue. The good news is that if you exercise regularly, you're likely to improve your immune function. "If you exercise too much, it can predispose you to coughs and sniffles," he points out. This is often the case for excellent athletes who train every day, such as triathletes . "But what we do know is that if you exercise at a moderate level, your immune system improves such that you're probably at a lower risk... What is this passage mainly about? A) Relationship between exercises and flu. B) How to do exercises. C) How to cope with flu. D) When to do exercises.

Ques: For hundreds of years, Japan has been hit, from time to time, by enormous tsunamis. These awful sudden risings of the sea are caused by earthquakes or underwater volcanic action. The story of the boy Yuuki is the story of such a disaster. Yuuki lived with his family in a sea-side village, below a small mountain. One day, as he played on top of the mountain, he felt an earthquake beneath his feet. It was not strong enough to frighten anybody and passed quickly. Soon after, however, Yuuki noticed the sea darken and begin running away from the shore very fast, leaving behind wide stretches of beach that had never been exposed before. With a gasp, Yuuki remembered reading that just before a terrible tsunami, the sea suddenly and quickly rolls backward. He ran to the beach, warning the villagers who had gathered to admire the huge new stretch of beach. "Get back!" shouted the boy. "There is terrible danger!" But no one listened. They laughed at him and continued playing in the new sand and watching the sea roll backward even more. Desperate, Yuuki could think of only one thing to do. He lit a tree branch, raced to the rice fields and began burning the stacks of harvested rice. Then he called out, "Fire! Fire! Everyone run to the mountain! Now!" When everyone reached the mountain-top, a villager cried out, "Yuuki is mad! I saw him set the fire." Yuuki hung his head in shame, but said nothing as the villagers cursed him. Just then, someone cried, "Look!" In the distance what seemed to be a huge dark line was speeding towards the shore. As it got nearer the people realized the long thin line of darkness was the returning sea, towering like a mountain. The villagers watched in terror as the water struck the shore, smashing over their homes then tearing out the land as it receded. On the mountain everyone stared speechlessly at the destruction below. "I'm sorry I burned the fields," said Yuuki, his voice trembling. "Yuuki," village-chief answered. "You saved us all." The... What were the people planning to do before the tsunami struck their village? A) Celebrate the rice harvest. B) Play on the beach. C) Climb the mountain. D) Harvest the rice crop.
