Thursday 选词填空
本文介绍了一款特别的肉丸——猛犸象肉丸。它是由科学家利用猛犸象DNA在实验室培育出的细胞制成的，并非真正的猛犸象肉，这种技术可在不伤害动物的情况下生产肉类。
1. D 在would后用动词原形，再结合选项和语境可知，如果它是用猛犸象肉制成的，你会吃吗？故选D。
2. E 由下句People have not seen this kind of meatball for at least 10,000 years.可知，人们至少有一万年没有见过这种肉丸了。因此，这张照片展示了一个特别的肉丸。
3. A 由上句But it did not come from a real mammoth.和常识可知，现在没有猛犸象了，表客观事实，应用一般现在时；且这是there be句型，缺少be动词。故选A。
4. C 由句意和选项可知，为了制作它，食品科学家使用了猛犸象的DNA。
5. B 由本句的without harming animals和下句But you won’t see mammoth meatballs any time soon.可知，人们不用伤害动物就能吃到肉。
