How does fake ‘meat’ taste?
What comes to mind when you hear the phrase “space meat”? It sounds quite weird. But in fact, it could very well be the future of the human diet.
A Russian astronaut recently “grew” meat aboard the International Space Station. Yes, you read that right - he grew it using cells provided by an Israeli company called Aleph Farms. But in fact, he was not the first person to create lab-grown meat. Dutch scientist Mark Post grew the first lab meat in 2013.
But why bother growing meat in a lab when we can get the real thing from cows? For one thing, lab-grown meat is healthier. “We gain greater control over what the meat consists of(由……组成), for example its fat content,” Post said in an interview with The Atlantic. Lab-grown meat is also free of the chemicals that are used on farms, such as pesticides(农*) and growth hormones(激素).
Are there other ways to replace(代替) regular meat? McDonalds is trying to do so with the P.L.T., which stands for plant, lettuce and tomato. The first P.L.T. burgers are already being sold in Canada, according to the fast food company.
The “meat” in the P.L.T. is made out of Beyond Meat, a plant-based meat substitute( 替代品 ) created by a company from Los Angeles, US. The company uses pea, rice and bean proteins to produce patties(肉饼) that look and taste like real meat.
Experts doubt whether these products are healthier than real meat. But they have already proven to be a success, with several fast food companies already offering such products on their menus, according to Fox Business.

本文是一篇说明文。文章主要介绍了实验室里培养出的肉可能更加健康，科学家们还发明出一种肉的替代品，完全是素的，但这是否比真正的肉健康，还有待讨论。
38．细节理解题。根据第三段“A Russian astronaut …Space Station”可知，一位俄罗斯宇航员最近在*空间站上种肉。故选A。
39．细节理解题。根据“For one thing, …for example its fat content,”，因为人类能控制这些肉的组成，比如脂肪含量，所以实验室里培养的肉更加健康。故选D。
40．细节理解题。根据“P.L.T., which stands for plant, lettuce and tomato.”以及“The “meat” in the P.L.T. … meat substitute”可知，P.L.T是植物、生菜和土豆的缩写，由此制作的汉堡完全没有肉，都是素食，所以都是由植物蛋白制作而成。故选B。
41．推理判断题。根据最后一段“Experts doubt whether these products are healthier than real meat.”可知，这些产品是否比真正的肉更加健康，专家们对此表示怀疑，所以这种素食可能并不比真正的肉健康。故选C。
