第一节（共8小题；每小题2分，满分16分）

　　阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

　　3D printing is becoming more and more popular. We are now able to create things we need very quickly and easily using 3D printers. But can you imagine printing food?

　　Some scientists are trying to revolutionize the dining experience by doing this. They hope that having a 3D printer in the kitchen will be as common as the microwave oven or blender.

　　Scientists say that it'll be quite easy: you simply have to select a recipe and put the raw food 'inks' into the printer. You can also modify the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals.

　　Using 3D printers to create your meals would also be saving the environment. There would be less need for traditional growing, transporting and packaging processes as food production would be a lot more efficient. For example, alternative ingredients(原料) such as proteins from algae, beetroot leaves and insects could be converted into tasty products.

　　Printing food could also help people who suffer from dysphasia (a swallowing disorder). They could program the printer to print softer versions of their favorite foods so that they would not have trouble in swallowing them.

　　However, some people think that a future of 3D food printing would be a disaster. It could take away many jobs, including those from growing, transporting and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes could be printed from a raw "food ink". Likewise, traditional cafes and restaurants might lose business. Also, there are concerns about the nutritional value of printed food: is it really possible to be get the nutrients we need from food--based inks and gels(凝胶)?

　　What's more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pleasure of cooking is dead and meals can be created at the touch of a button.
