Ⅲ.[2018·台州改编] 阅读理解
3-D printing is becoming more and more popular.We are now able to print things such as clothing, musical instruments and even cars.People and businesses are able to create the things they need very quickly and easily by using 3-D printers.
But can you imagine printing food? Some scientists are trying to change the dining experience completely by doing this.They hope that having a 3-D printer in the kitchen will become as common as the blender or the microwave.Scientists say that they are easy to use: you simply have to choose a recipe and put the uncooked food “inks” into the printer to make the food which is the same as that in the recipe.This means that it would be very quick and easy to create tasty and healthy meals.
Using 3-D printers to create your meals would also be saving the environment.There would be less need for traditional growing, shipping and packaging steps as food production woul
d be a lot quicker and better.For example, tree leaves and insects could be turned into tasty products! Printing food could also help people who have a swallowing(吞咽)trouble.They could program the printer to print softer kinds of their favourite foods so that they would not have difficulty swallowing them.
However, some people think that a future of 3-D-printed food would be a disaster.It could take away many jobs, including those for growing, shipping and packaging food.Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked “food ink”.Traditional cafes and restaurants might lose business, too.Also, there are worries about the healthy value of printed food: Is it really possible to get what we need from food-based “inks” or something like that?
