Look and Say All about sneezing What’s the boy doing? What may the text be about according to the title and picture? All about sneezing 1 If you had to list different ways of protecting yourself, sneezing probably would not be on the list. But when you sneeze, that is exactly what is happening. Sneezing helps you protect yourself from things like germs, dust, and smoke. In fact, it is the body's way of getting rid of things that may harm you. 2 People cannot really control their sneezes. If something starts tickling the inside of our nose, our brain takes over. It knows that something inside the nose should not be there, so it sends a message to the body to get it out. 3 When we sneeze, many things happen in a very short time. Usually, our eyes shut,our tongue presses against the top of our mouth, and the muscles in our stomach and chest get tight. Next, there is a sudden blast of air coming out of our lungs and then our nose. As the air goes out our nose, it carries germs, dust, and tiny drops of water with it. 4 Some unusual things can also make us sneeze. For example, some people sneeze when they look at a bright light. If people have an allergy, certain plants or animals might also make them sneeze. If they are allergic to certain plants, they might sneeze a lot in the seasons when the plants bloom, but not in others. If they are allergic to dogs or cats, they usually cannot have one as a pet. 5 While sneezing is good for the person doing it, it can be very bad for the people nearby. Sneezing is one way that diseases spread. Millions of germs from one sneeze can travel up to about 8 metres at a speed of 160 kilometres per hour! These germs can stay in the air, and if other people breathe in those germs, they can get sick too. 6 If you sneeze, always cover your nose and mouth. After that, make sure to wash your hands. Sneezing helps your body protect itself, but doing these two things can help you protect everyone else! Read the text quickly and match the correct main idea with each paragragh.
