(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.

短篇新聞(二)
Post教授正在研發(fā)一種在實驗室種植肉類的辦法，因為他認為畜牧對環(huán)境和動物都不利，而且也無法滿足人類日益增長的肉類需求。
他的目標(biāo)是創(chuàng)造出一種樣式和口味與真實漢堡相似的人造漢堡。但是根據(jù)我從他實驗室里看到的，該實驗仍處于進展當(dāng)中。
因為人造肉是用干細胞培育而成，無色無味，因此食物專家用面包屑，焦糖和藏紅花為其加味、用果汁為其上色。所有用料添加完畢后進行烹制，最后制成漢堡由兩位美食作家品嘗。
起初的試驗階段表明這一漢堡的口味有所欠佳，但是Post教授表示，漢堡會越來越美味的。
問題3.為什么Post教授要研發(fā)在實驗室里種植肉類的辦法?
問題4.為什么食物專家要在人造肉里加果汁?
參考答案：
【小題3】B
【小題4】D
習(xí)題解析：
【小題3】新聞開頭提到了 Post 教授在研發(fā)一種在實驗室種植肉類的辦法，隨后給出了具體原因：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，即畜牧對環(huán)境和動物都不利，而且也無法滿足日益增長的對肉類的需要。四個選項中，符合新聞原文的是 B項，故選 B。
【小題4】本題考查食品技師必須往種植的肉里邊添加果汁的原因。新聞中提到種植的肉顏色慘白而無味，隨后緊接著說到 so food technologists have had to mix in breadcrumbs, caramel and saffron to addflavor and juice to add color，所以，往種植的肉里添加果汁的原因是為了增加顏色，故選 D。
