①Chemistry is everywhere in our daily life.Sometimes it's easy to see.At other times，it can be very hard to see the everyday chemistry at work，but nearly everything you touch has some chemicals（化学物质） in it.
②Chemistry helps to make products for use.Something as simple as toothpaste has at least three chemicals that keep your teeth clean.Other things in your daily life are created by chemistry，such as hair products and soap.Without chemistry，we would never have known that we need soap to get the oil out of clothes.
③Chemistry also helps us understand the world around us.Thanks to chemistry，we know bleach （漂白剂） can't be mixed with vinegar （醋），because the mixture can produce harmful gas.
④Chemistry plays a big role in food preparation.Cooking food causes it to go through a chemical change.That is why cooked food often tastes different from uncooked food.Too much or too little of any chemical material makes a difference to the result of baking （烘焙）.For example，the cake can be too soft or too hard.
⑤Chemistry isn't something that just lives in a laboratory，it's something that you meet hundreds of times in life.Knowing how chemistry works will give you a greater understanding of the life.
