A smile is one of the most common examples in different countries. While Americans smile freely atstrangers,in Russia this is considered strange and even impolite. In Asian countries a smile isn&39; tnecessarily an expression of joy but it can be used to express pain.
The acceptable physical distance is another major difference. In Latin America and the MiddleEast the acceptable distance is much shorter than what most Europeans and Americans feet comforta-ble with. Hand and arm movements as a form. of body language are also very different amongcountries. Handshakes are usually acceptable almost everywhere, even between strangers;however,kissing on the cheek and touching on the shoulder or other body parts aren&39; t. For many people inAsia and other parts of the world, such actions are seen as a violation (侵犯) of one&39; s personalspace. This is why you should not touch others easily.
Eye contact(目光接触)is one of the forms of body language where the differences are most strikingInAmerica and Latin America looking the other person in the eye is a sign of respect. But in Asian countries,prolonged(过长的)eye contact is especially rude,so you should try your best not to do that.

By the end of this century this may not be mere speculation. Scientists are already looking into the possibility of using some of the available ice in the Arctic and Antarctic. In these regions there are vast ice-caps formed by snow that has fallen over the past 50,000 years. Layer upon layer of deep snow means that, when melted, the snow water would be pure, not salty as sea-ice would be. There is so much potential pure water here that it would need only a fraction to turn much of the desert or poorly irrigated parts of the world into rich farmland. And what useful packages would come in! It should be possible to hack off a bit of ice and transport it! Alternatively perhaps a passing iceberg could be captured. They are always breaking away from the main caps and floating around, pushed by currents, until they eventually melt and are wasted.
Many icebergs are, of course, much too small to be towed any distance, and would melt before they reached a country that needed them anywhere. It would be necessary to harness one that was manageable and that was big enough to provide a good supply when it reached us. Engineers think that an iceberg up to 11 kilometres long and 2 kilometres wide could be transported if the tug pulling it was as big as a supertanker! Even then they would cover only 32 kilometres every day. However, once the iceberg was at its destination, say at one end of Hong Kong harbour, more than 7,000 million cubic metres of water could be taken from it! That would probably be more than enough for Hong Kong even in the hottest summer! But no doubt a use could be found for it.
Apparently, scientists say, there would not be too much wastage in such a journey. The larger the iceberg, the slower it melts, even if it is towed through the tropics. This is because when the sun has a bigger area to warm up, less heat actually gets into the iceberg. The vast frozen center would be unaffected.
Even with the giant tug that would have to be available to tow an iceberg seven miles long, the voyage would take many months from the Antarctic to Hong Kong, for example, but as stronger engines are built and more is known about sea currents, the journey could get shorter and shorter and thus the wastage less and less. Airline pilots have learnt to use jet streams ten miles above the earth to increase speed and save fuel so, surely, a boat towing an iceberg could make use of fast-flowing currents and avoid warmer water.
The main idea of the first paragraph is that______.
A．much of desert has been changed into rich farmland already
B．the problem of drought could easily be solved all over the world
C．ice from the polar area may be used to solve the problem of drought
D．it is possible to solve the problem of drought in many countries
