Question

    Described as the world’s most environmentally friendly protein（蛋白质）, Solein is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes (微生物) are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’s a chemical change process similar to beer brewing. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour.

“It is a completely new kind of food, a new kind of protein, different to all the food on the market today in how it is produced as it does not need agriculture.” Dr Pasi Vainikka, the chief manager of Solar Foods told The Guardian. The process used to produce Solein—changing hydrogen and carbon dioxide is amazing, as the wonder food can be produced anywhere in the world. It’s also 10 time-efficient than photosynthesis (光合作用), and 10 to 100 times more environment and climate-friendly in water use than animal or plant-based food production.

“Solein also contains all the essential amino acid (氨基酸),but because it is produced using carbon and electricity, it does not require large amounts of land to produce, ” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.”

While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for sustenance. The Helsinki-based company plans to open its first Solein factory at the end of 2021 and increase production to two billion meals per year by 2022.

1.Why is Solein described as environmentally friendly?

A.Because it is man-made by using electricity.

B.Because it contains all the nutrition people need.

C.Because it is made consuming less land and energy.

D.Because it is produced from water and carbon dioxide.

2.What does Solar Foods expect of Solein?

A.It’ll have a rewarding future.

B.It’ll reach consumers in 2020.

C.It’ll challenge traditional protein production.

D.It’ll be a complete replacement for plants and animals.

3.What does the underlined word “sustenance” in last paragraph mean?

A.survival B.food

C.material D.support

4.Where is this text most likely from?

A.A textbook. B.A novel.

C.A magazine. D.A brochure.

【解析】

本文是一篇说明文，介绍了世界上最环保的蛋白质Solein的生产原理和特点。

1.细节理解题。根据第三段中的“but because it is produced using carbon and electricity, it does not require large amounts of land to produce, ” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.””可知，因为Selein是用碳和电生产的，所以不需要大量的土地来生产，它的另一个独特特性是它能够直接从二氧化碳中获取碳，而不需要糖源，由此可知，Solein被认为是环保的是因为它占地小、耗能少，故C项正确。

2.细节理解题。根据最后一段中的“While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity,”可知，虽然太阳能食品公司预计在未来20年里，Solein不会挑战传统的蛋白质生产方法，但它确实有望成为人类的新收获，由此可知，太阳能食品公司预计Solein会有一个美好的未来，故A项正确。

3.词义猜测题。根据画线词前的“it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for”可知，太阳能食品公司预计Solein将成为人类的新收获，目前为止我们的食物来源还只是依靠动植物，鉴于这一点，这项技术的意义非常重大，由此可知画线词词义为“食物”，故B项正确。

4.推理判断题。通读全文可知，本文主要介绍了世界上最环保的蛋白质Solein的生产原理和特点，这属于科技范畴，因此文章最有可能出自于科学杂志，故C项正确。
