Researchers at Michigan State University recently found that bees’ sense of smell(嗅觉) is very good. They can use antennae on their heads as “noses” to sense the chemicals of cancer(癌症化学物质).
A study showed that bees can smell lung(肺) cancer from a person’s breath. “Like bees, many animals’ world is based on smell. Their sense of smell is very good,” Debajit Saha, one of the researchers, said. “There is quite a bit of research that shows when some cancer grows inside our body, our breath actually changes. Our research does show that bees can find lung cancer and possibly other illnesses from the smell of those chemicals.”
Saha and his team placed bees near chemicals similar to those in a lung cancer patient’s(病人) breath. These bees could tell the difference between cancer breath and healthy breath 93% of the time. They could also tell different kinds of lung cancer. This study can help doctors find cancer earlier.
Saha said finding cancer this way would be a big improvement. In the past, many times we found the cancer late, when the situation became too serious to control.
Using animals to find cancer isn’t new. At a dog center, researchers are training dogs to smell cancer. Dogs are good at smelling and they work with humans well.
Some researchers say dogs are better at finding cancer than machines. A dog’s sense of smell is 10,000 to 100,000 times sharper(更灵敏的) than humans’. But scientists hope to create a machine that can find illnesses like dogs for the health of humans and animals.
81. What can bees do using their antennae?
82. What happens to a man’s breath when cancer grows inside his body from the study?
83. What’s the good point of using bees to find cancer according to Saha?
84. Why are dogs good at finding illnesses?
85. Do you think scientists can create a machine to find illnesses? Why?

答案
81. 根据“They can use antennae on their heads as “noses” to sense the chemicals of cancer(癌症化学物质).”可知蜜蜂用触角的作用。
82. 依据“There is quite a bit of research that shows when some cancer grows inside our body, our breath actually changes.”可知癌症在体内生长时人呼吸的变化。
83. 从“This study can help doctors find cancer earlier.”能得出用蜜蜂找癌症的优点。
84. 由“Dogs are good at smelling and they work with humans well.”可知狗擅长找疾病的原因。
85. 这是开放性问题，可根据对科学发展的理解回答，比如基于科技不断进步等。
81. They can use antennae on their heads as “noses” to sense the chemicals of cancer.
82. Our breath actually changes.
83. This study can help doctors find cancer earlier.
84. Because dogs are good at smelling and they work with humans well.
85. Yes, I think so. Because science and technology are constantly developing and making progress. (答案不唯一，合理即可)
