Scientists from The French National Center for Scientific Research （CNRS） found that some ants have a good sense of smell.“But more tests must be carried out before they could be used in hospitals，”the team said. The scientists did tests with 36 ants, smelling cells in the lab. First, they let the ants smell some cancerous human cells. Every time the ants smelt cancerous 刷速度 返回目录 16 cells, they were rewarded with sugar solution （糖溶液）.In the second step, the ants were put into two different smells. One was a new smell of healthy cells and the other was still the smell of the cancerous cells. Once the ants found the cancerous cells successfully, the researchers made them smell different cancerous cells. As such, the scientists found that ants could tell between cancerous and healthy cells and between two cancerous cells. This isn’t the first time that scientists have used the animals’ sense of smell to find cancerous cells.“Dogs are good at finding something with their noses. However, training dogs to do so needs several months or a year. 刷速度 返回目录 On the other hand, ants can be easily raised in a short time. They are inexpensive, and hundreds of them can be trained with fewer times,” scientists pointed out. “This study shows that ants are able to learn very quickly. The way can be used for other tasks including finding danger or other illnesses,” scientists added.#1.4 阅读B篇·语篇导读 文章主要介绍了蚂蚁能嗅出人体癌细胞的特殊技能。 刷速度 返回目录 14.What can we know from CNRS’s study？( ) C A.Ants help humans keep off cancer.
