Questions 3 and 4 will be based on thefollowing news item.

　　3

　　A.Professor Post is an environmentalist as well.

　　B.Livestock cannot meet the demand for meat.

　　C.Meat grown in a lab is much more delicious.

　　D.Growing meat in a lab cost less than raising livestock.

　　4

　　A.The grown meat tastes just like the real thing.

　　B.The grown meat looks pale and tastes good.

　　C.The grown meat grows from stem cells.

　　D.The grown meat needs adding color.

　　News Item Two

　　(3) Professor Post is developing a way to grow meatin a lab because he believes that livestock farming isnot good for the environment, not good for animalsnor, he says, is it going to satisfy the growingdemand for meat.

　　His aim is to produce a burger that looks and tastes just like the real thing but from what Isaw at his lab, which is still a work in progress.

　　(4) The flesh, grown from stem cells, is pale white and tasteless, so food technologists havehad to mix in breadcrumbs, caramel and saffron to add flavor and juice to add color. Themixture is then put together to make the burger that will be cooked then eaten by two foodwriters.

　　Initial testing during the development process suggests that it won't taste great, but accordingto Professor Post, it will taste good enough.

　　3.Why Professor Post is developing a way to grow meat in a lab?

　　4.Why do the food technologists have to add juice to the grown meat?

　　短篇新闻(二)

　　Post教授正在研发一种在实验室种植肉类的办法，因为他认为畜牧对环境和动物都不利，而且也无法满足人类日益增长的肉类需求。

　　他的目标是创造出一种样式和口味与真实汉堡相似的人造汉堡。但是根据我从他实验室里看到的，该实验仍处于进展当中。

　　因为人造肉是用干细胞培育而成，无色无味，因此食物专家用面包屑，焦糖和藏红花为其加味、用果汁为其上色。所有用料添加完毕后进行烹制，最后制成汉堡由两位美食作家品尝。

　　起初的试验阶段表明这一汉堡的口味有所欠佳，但是Post教授表示，汉堡会越来越美味的。

　　问题3.为什么Post教授要研发在实验室里种植肉类的办法?

　　问题4.为什么食物专家要在人造肉里加果汁?

　　参考答案：

　　【小题3】B

　　【小题4】D

　　习题解析：

　　【小题3】新闻开头提到了 Post 教授在研发一种在实验室种植肉类的办法，随后给出了具体原因：he believes thatlivestock farming is not good for the environment, not good for animals nor, he says, is itgoing to satisfy the growing demand for meat，即畜牧对环境和动物都不利，而且也无法满足日益增长的对肉类的需要。四个选项中，符合新闻原文的是 B项，故选 B。

　　【小题4】本题考查食品技师必须往种植的肉里边添加果汁的原因。新闻中提到种植的肉颜色惨白而无味，随后紧接着说到 so food technologists have had to mix in breadcrumbs, caramel and saffron to addflavor and juice to add color，所以，往种植的肉里添加果汁的原因是为了增加颜色，故选 D。
