Comprehension: Teeth


TEETH




Everyone has several different types of teeth. The teeth in the front of your mouth, and the easiest to see, are called incisors. There are four incisors on the top and four on the bottom.  These teeth are used for cutting and chopping food. 

The pointed teeth on either side of your incisors are called canine teeth. People have a total of four canine teeth, two on top and two on the bottom. They are pointed and sharp. They are used to tear food. Next to your canine teeth are the premolars.
You have eight premolars in all. Premolars are bigger, stronger, and have ridges – all of which makes them perfect for crushing and grinding food.

 Finally, there are your molars. You have eight of these. Molars are the toughest of the teeth. They are wider and stronger than premolars, and they have more ridges. Molars work closely with your tongue to help you swallow food. 


The tongue sweeps chewed food to the back of your mouth, where the molars grind it until it is mashed up and ready to be swallowed. By age twenty, four more molars grow in the back of the mouth, one in each corner. These are called wisdom teeth. People do not need wisdom teeth now, but many years ago these teeth were necessary to help people chew tough plants, which were an important part of the human diet. Now, many people get their wisdom teeth pulled by a dentist.

Saturday Classes 2024

Saturday, May 18, 2024 Class 3's                                      COMPREHENSION I dared not stir out of my castle for days, lest some savage should capture me. However, I gained a little courage and went with much dread to make sure that the footprint was not mine. I measured my foot against it. Mine was not nearly so large. A stranger, maybe a savage, must have been on shore, and fear again filled my heart. I determined now to make my house more secure than ever. I built another wall around it, in which I fixed six guns, so that, if need be, I could fire six in two minutes. Then I planted young trees all around. I feared my goats might be hurt or stolen from me, so I fenced round several plots of ground, as much out of sight as possible, and put some goats in each plot. I did all this, while I lived with a terrible fear in my mind that I might one day meet an enemy. I had lived eighteen y...

First, a domestic tourist is a person who spends at least one night away from their normal home but still within their own country. Some people call this a ‘staycation’.  Then, there are regional tourists. This is a tourist who travels within a certain region.
