[EX Q]: Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed   hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding   among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved   in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.

[EX Q]: Article: The wombat  is in trouble. Some are dying in bushfires, or being shot by farmers. Others are scratching themselves to death because of a mite  infection. Only 115 of one species - the northern hairy-nosed wombat - remain alive in the wild.  Wombats are endemic to Australia. They are found nowhere else. A wombat looks like an overgrown, stocky guinea pig, covered with thick grey fur and with a wide, flat, broad forehead. Fully-grown adults are about a meter long and about half a meter tall. They weigh about 40kg.  But while their looks are pretty straightforward, people throughout history have found it less easy to understand their behavior. The Aborigines  seem to have mixed feelings about them, According to one story, the wombat once said he was more powerful than the sun. After a competition, however, the wombat lost, and so today hides from shame, deep down in a hole. But another Aboriginal story tells of how wise the wombat can be. He comforts the other animals in the forest, after their friend, a cockatoo, has died, explaining to them all about forest spirits. Wombats are strong diggers, with very powerful front legs and sharp claws, usually used to dig winding holes in the ground for their homes. Yet despite their strong appearance, these animals are struggling to survive.  Many have been suffering a lot from a foreign mite, from foreign foxes, introduced for hunting by the early English settlers of Australia. Because of scratching, scars form over the wombats' eyes and ears, and infections occur, finally causing their death. Its population is so small that the group is becoming inbred . Competition with cattle and sheep for grass to eat, drought, bushfires, as well as dingo and feral dog attacks have all whittled away wombat numbers.   But fortunately, a group of committed volunteers and scientists, working with the local government, has now put up fences to protect the wombats from meat-eating animals, made holes for extra shelter, and is working with zoos to create developing programs. These conservationists are well aware they have little time left.
