科技前沿:来自实验室的“牛奶”
科技前沿:来自实验室的“牛奶”


Many people drink cow’s milk. But they are worried about animals at the same time. So more and more people stop drinking cow’s milk now.

They want to drink plant milk. This kind of milk comes from plants like nuts(坚果) or soy(大豆). But some of them don’t like its taste. They also worry that it may bring problems to the natural world. So they don’t drink plant milk, either.

Now scientists create(创造) a new kind of milk in the lab(实验室) for them. This new milk has real milk parts in it. It tastes like cow’s milk. To make it, we do not need any animals. No plants are needed, either. Scientists use genetically modified microbes(转基因微生物). These microbes make the milk parts. This new milk is better for both animals and the natural world. Why not have a try?

3.What is/are used to create this new kind of milk?

A Animals.

B Nuts.

C Soy.

D Microbes.

解析:选D。D细节理解题。根据第三段“This new milk has real milk parts in it.”和“These microbes make the milk parts.”可知,创造这种新型奶不需要动物,也不需要植物,需要的是微生物。故选D。

4.What is the writer’s attitude(态度) to this new milk?

5.The text(文本) may come from the part of _________ in a newspaper.

A life

B story

C science

D sports

解析:选C。C推理判断题。根据全文可知,本文主要介绍了科学家们通过转基因微生物制造出一种新型奶,这种新型奶既不需要动物,也不需要植物,属于科普类文章,故应刊载在报纸的科学版块,故选C。
