Question

【题目】Would you buy a car that released calming smells into the air when you are stuck in heavy traffic? Would you buy a robot that smells like a human being?

Many people have seen the 3-D computer-made environments of virtual (虚拟的) reality (VR). Now these virtual worlds will not just look and sound real. Researchers have created VR environments that even smell like the real things. With the new technology, users open a virtual door and step into a new environment, like a rainforest. After they enter this virtual world, special equipment releases forest-like smells into the air to make the experience seem more real.

Suzanne Fisher-Murray said, “It is a really wonderful experience that you have because you, re exploring this environment and you have smells with it.”

In the United States, Smell-O-Vision was designed to provide smells during the showing of a movie. The Smell-O-Vision system was once popular in the 1960s. Now, Emanuela Maggioni says it is close to becoming popular again. “The connection with emotions, memories, and ... the sense of smell,” Maggioni said. “It is unbelievable what we can do with technology.”

The uses for smell technology are not just limited to films and the performing arts. Researchers showed a computer program where users could imagine themselves driving a car. The system included a special smell- spraying machine. Dmitrijs Dmitrenko said, “We want to deliver the smell of lavender (薫衣草) every time the person drives over the speed limit. We choose lavender because it’s a very calming smell.”

Scientists are experimenting with smell instead of sounds or image-based alerts on telecommunications equipment. And businesses are already using smell to influence people’s behavior. “Not only...in stores…But on the other side, you can create and stimulate (刺激) immediate buying,” Maggioni said. “So you’re in a library and you smell coffee and actually you are unconsciously having the need to drink a coffee.”

【2】C

【3】D

【4】A

【解析】这篇文章主要讲了气味识别技术新发展引发科学家惊叹。

【1】细节理解题。由Researchers have created VR environments that even smell like the real things.可知使用嗅觉技术，研究人员使得虚拟现实环境像真正的事物一样去闻，选B。

【2】推理判断题。由In the United States, Smell-O-Vision was designed to provide smells during the showing of a movie. The Smell-O-Vision system was once popular in the 1960s.可推断出Smell-O-Vision的例子证明嗅觉技术之前已经被尝试，选C。

【3】由And businesses are already using smell to influence people’s behavior. “Not only...in stores…But on the other side, you can create and stimulate (刺激) immediate buying,” Maggioni said.可知商人使用嗅觉影响人们的行为，鼓励人们突然买一些东西，选D。

【4】主旨大意题。这篇文章主要讲了气味识别技术新发展引发科学家惊叹，所以选A。
