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 first defence against anything that tries to enter your body through the air.
Read Paragraph 1 and answer the questions.
Is sneezing a good thing for ourselves Why
It’s a good thing because it helps us protect ourselves from things like germs,dust and smoke. It is the body’s first defence against anything that tries to enter your body through the air.
What’s the process of sneezing
Read and Order
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.
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.
Read para.2&3 and put the sentences in order.
_____The brain sends a message to the body.
_____Something tickles the inside of the nose.
_____Air blasts out of the lungs and nose, carrying germs and dust.
_____The brain takes over and knows something shouldn't be in the nose.
_____Eyes shut, tongue presses against the mouth, and stomach/chest muscles tighten.
