With the high development of science and technology, almost in every few days there is a new invention coming out. We can call an invention significant if it can do much good to most people in the world. So, if I could invent something new, I would like to create a kind of thing that is related to the eating problem and try to make each dinner convenient. That invention should be a cooking machine.  

The cooking machine is used at home. If you want to cook a sort of meal, you just put the crude materials such as vegetable, meat into one of its input ports and oil or other spice sources into other input ports. Then choose the recipe from its control panel and press a button to start. After certain time, you can get you food at the output. The whole process does not need you to interfere. You can use the recipe stored in the machine or you can make your own special recipe added into it. There is a time-setting function with which you decide when to start the cooking. Furthermore the computer can analyze your meal to tell you whether you have got optimal nourishment.  

Why do I want to invent such thing? For one thing, the machine can be used for saving the time which people spend on cooking. Eating is an indispensable event which happens in our daily lives. Usually, we spend lots of time in cooking if we want to eat well. It is not worth it because we have other significant thing to do like keeping fit, reading.  

For another, we need a nutritionist on line to tell us how to eat to be healthy. Nutrition is a science in that nutritionists study how to keep nutrient balance. If you eat too much, too little or eat something too much, too little, you can all make you sick. We need a specialist to give us instructions on our diets.  

In conclusion, what I want to invent is a cooking machine not only because it can emancipate us from the time consuming cooking but also because we can get scientific nutrient instructions in our daily lives.
