Question

    Drinking milk every day is good for your health. However, if one day someone gives you a cup of cow-free milk, will you still want to have a drink?

Recently, an American company named Perfect Day surprised the world with its synthetic (合成的) milk. The milk looks and tastes almost like cow milk and has all the same nutrients (营养素).

The creators of Perfect Day are two young scientists, Ryan Pandya and Perumal Gandhi. Working in different cities, they didn’t know each other at first. But they shared the same crazy idea about making milk without the help from cows. They thought it would make the world a kinder, greener place. After they met, they started working on a way of making their dream a reality.

The secret to making cow-free milk? Yeast (酵母), 3D printing technology and old fermentation processes (发酵方法). They have developed a process quite like making beer. The two scientists also say their milk has longer shelf life than the real milk. What’s more, it’s delicious, safe and Earth-friendly. “We want people to enjoy our milk, while leaving a kinder footprint on the planet,” say the two young men.

However, they also know it will be a long way before people accept their synthetic milk.

Before people accept the synthetic milk, maybe we should do something to reduce waste. A store in Scotland is doing such a thing. It sells milk in a vending machine (自动售货机). The vending machine allows people to refill their glass bottles with fresh milk. “The milk vending machine lets us work with a local farm to get really tasty milk for our customers without wasting plastic containers (集装箱),” one worker from the store said. It helps to save the store about one hundred plastic containers a day.

【解析】

本文是一篇说明文。描绘了一种不亚于真正牛奶的合成牛奶以及它能带给世界的变化。

1.细节理解题。根据第一二段“if one day someone gives you a cup of cow-free milk, will you still want to have a drink? Recently, an American company named Perfect Day surprised the world with its synthetic milk.”可知，这种合成牛奶其实就是一种免牛牛奶。故选B。

2.词义猜测题。根据原文“The vending machine allows people to refill their glass bottles with fresh milk.”自动售货机允许人们用鲜牛奶把玻璃瓶再次装满。分析整段内容，讲的是如何节省包装材料，那么重复使用是最好的办法，所以此处意为“再装满”。故选B。

3.推理判断题。根据第三段“They thought it would make the world a kinder, greener place.”可知，设计者的初衷是为了使得这个世界更宽容、绿色。故选A。

4.主旨大意题。根据第三段“They thought it would make the world a kinder, greener place.”可知，设计者的初衷是为了使得这个世界更绿色。故选D。
