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 reexploring 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. "People will be impressed by 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 warnings 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."

　　To an outsider, any culture can seem confusing. And the UK's got a thing or two that raises a few eyebrows. However, understand the reasons and things might be less puzzling. 36 .

In a world where 61% of nations drive on the right, Brits drive on the left. Why? Most people think it goes back to Medieval (中世纪), maybe even Roman times. 37 when you remember that right-handed people wear a sword on their left side. Travelling on the left allowed you to keep your weapon arm toward your opponent (对手), who would be on your right. This practice continued until the 18th century when a law was passed requiring all traffic crossing London Bridge to keep to the left.

Visitors to the UK that have just washed their hands in an old-fashioned sink(水槽) might be wondering why one tap is only for hot water, the other cold. 38 . So, why? It relates to a time when hot and cold water were kept separate to prevent pollution. Drinkable cold water came from a main supply, but hot water came from tanks and was not considered suitable for drinking. So they were kept apart.

Millions of people drink tea worldwide, but the Brits put milk in theirs. Why? This mysterious practice relates to the quality of china cup used in the 18th century when tea was first imported. For the majority of Brits, the cups available couldn't stand the heat of the boiling water and would break, so milk was added first. 39 . And this practice soon became a national habit.

40 . As you can see, Brits have perfectly clear reasons for left-hand driving, two-tap sinks and tea with milk. Even if they still seem strange, at least now you're in the know.

A. This makes it difficult to improve

B. There is a method to the madness

C. This unusual behavior makes sense

D. You can know the origins of the practices

E. Either can make washing very uncomfortable

F. This cooled the cup enough to resist the boiling water

G. Here are the reasons for three of Britain's more puzzling practices
