高三英语单项填空中等难度题查看答案及解析

There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.

The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.

For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel’s Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.

But don’t worry if you’re not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the “overall sensory experience”, according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.

As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products.　 Recently both the USDA and the Food and Drug Administration(FDA) announced that they will begin jointly controlling the new “cell-based meat” category.

Many of us have concerns about the challenges facing future generations as our global population increases and the earth’s natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.

1.Why do some companies begin to develop new kinds of meats?

A.To analyse the causes of air pollution.

B.To stress the importance of protecting wild animals.

C.To make people less interested in eating meat and more healthy.

D.To meet people’s demand for meat in environmentally friendly ways.

2.What’s special about the lab-grown meats of Jet Eat?

A.They cost less. B.They are plant-based.

C.They are more delicious. D.They are available on the market now.

3.Which of the following is a barrier lab-grown meat industries must deal with?

A.How to let people accept the meat. B.How to give the meat an elegant name.

C.How to produce the meat in large amounts. D.How to reduce the cost of making the meat.

4.What’s the author’s attitude towards lab-grown meats?

A.Supportive. B.Opposing. C.Ambiguous. D.Cautious.
