Language shows the environment where we live. We name the things around. Usually, the important things own many specific names, while the less important things only have some general names. So in one culture, people may have a large vocabulary to describe a certain object, while in another culture, such vocabulary is small.
For instance, the Chinese have many words for “rice” and for “family members”. The British use many different expressions for “rain”. Kids growing up on a farm may be able to offer ten different words for plow, a farming tool.
In some cultures, there is an amazingly large vocabulary to describe a certain thing. Eskimos have about 100 words for snow. For them, snow is so important to life that each of its forms and conditions has to own a name. They divide snow into four main categories, such as snow lying on the ground, snow floating in the sky, snow piling up, and snow piles. These different kinds of snow will tell them different weather conditions. It’s the same with the Arabians, whose life depends much on camels. In the Arabic language, according to camels’ appearance, characters, drinking behaviours, and the roles they play, there are hundreds of different words for the camel and all of its parts. Snow and camel are far less important in English-speaking cultures, and the single words “snow” and “camel” can usually satisfy their needs. When the needs become more specific, however, they can make up longer phrases to meet the needs: “corn snow”, “flying snow”, “big camel”, “funny camel”, etc.
As we can see, there is a 4 between the words and the ideas of that culture. So it’s not hard to understand that each culture passes on its ideas and thoughts through word.

A ． Opinions. B ． Examples. C ． Conclusions. D ． Reasons.

A ． By inventing new words. B ． By using other sentences.
C ． By making up longer phrases. D ． By translating from another language.
4 ． Which word is the most suitable here?
A ． difference B ． connection C ． change D ． distance
“I have no special talent. I’m only passionately curious.” This famous quote from Albert Einstein might tell the reason for his success. When Newton discovered gravity, and when Thomas Edison invented the light bulb, their curiosity was greatly satisfied. If they hadn’t been curious, what a loss for humans!
There is a common truth that intellectual curiosity ( 求知欲） contributes to school performance more than intelligence. Some studies also show there are benefits of curiosity in improving the long-term level of learning and memory, and a lot of positive results are connected with curiosity.
It has been known that both animals and humans are willing to take a risk to satisfy their curiosity despite knowing that the result will remain unchanged. Despite there being different views on the reason for curiosity, most experts reach an agreement that like the way the stomach looks for food, our brain looks for knowledge. People and animals are eager to know things because getting that information means a reward.
An interesting thing is that our brain will release a pleasure-related chemical when it has been given new information, making seeking information much like eating — another pleasant activity. Researchers newly found that increasing the release of the chemical greatly increased the curiosity in animals. However, how exactly the chemical plays a role still remains a mystery.
Considering the present level of research on curiosity and the driving force of curiosity, including scientific curiosity, more research should be carried on in this field. It’s safe to say that curiosity itself will help uncover curiosity. And remember even though the idiom says “Curiosity kills the cat”, it ends with satisfaction bringing it back.
