Which floor am I on?! Blog This is a picture I took in an elevator in Hong Kong. If you look carefully, you'll see that the numbers 4, 13, 14, and 24 are missing. This is because Hong Kong was once a British colony, so the culture of Hong Kong reflects both Chinese and British superstitions: 4 is considered an unlucky number in China, while 13 is in the U.K. It is interesting to learn about the differences in culture and customs between countries, and knowing the history of a place helps us understand local customs. 3 M 110 10 18 25 9 17 23 2 8 16 22 1 7 15 21 G 6 12 20 LG 5 11 19 Elevator buttons in a Hong Kong building Task 1 Analyze the passage.

4 We created two versions of the menu. Half of the subjects saw a menu that had the word "classic" highlighting the health boost option, whereas the other half saw the health boost highlighted by the word "new." Then our subjects made their choices. 6 As predicted, when the subjects were in the tidy room, they chose the health boost more often almost twice as often - when it had the "classic" label: that is, when it was associated with convention. Also as predicted, when the subjects were in the messy room, they chose the health boost more often more than twice as often when it was said to - be "new"; that is, when it was associated with novelty. Thus, people greatly preferred convention in the tidy room and novelty in the messy room. O difference.

The natto powder provides not only clean water but also business opportunities for local people. Locally employed people sell the powder and water at low prices. Right in front of their potential customers, they demonstrate how to purify dirty water, show the water quality, and then sell both the powder and water. They enjoy much better lives with the steady income. When they go around their neighborhoods, they are thanked again and again by their customers. They say, "I'm really happy because I can now cook with clean water," or "I can give my children safe water to drink." The natto powder makes a difference to the lives of many people in the world. It seems to have stuck in their minds and spread an ever-widening circle of smiles.

く読んでから答え When people look for a job, some choose a workplace that is close to where they live, while others move to a new town or city in Japan. There are other choices, too. Some of them decide to go to other countries to work. What are the reasons for this? They can have experiences that they cannot have in their own countries while working abroad. Also, they can learn a local language by using it not only at work but also at other times. This can help their future career as well. On the other hand, people have to face issues with differences in customs at work. It can take a long time to get used to the new work environment if things are very different from their own countries. Also, people cannot easily visit their family and friends back home. This can cause them to feel lonely. ①These days, some of people verse. ecially thers media anytime, earn new ity. me young themselves ch personal a dangerous decide to other go countries to work. 質 大文字?OKか * It has benefits, such as They can have edia.
