Kick the Bucket This means"to die".Many people consider the term to have come from a guilty man standing on an upturned bucket which was then kicked out from under his feet leaving him to hang,but there is no written evidence that this is the case.In fact,it is more likely from a different type of bucket entirely.In butchery ,when a pig was killed it would be hung from a pole.It is mostly likely that in his death throes ,the pig's feet would bang against the rail to which they were tied.Therefore,kicking the bucket was a term referring to the last actions of the pig before he finally died.

[EX Q]: Article: Former South African President Nelson Mandela who was treated for a recurring lung infection, dies on Dec. 5th, 2013, at the age of 95. People around the world are mourning the loss of the country's first black president. He was often called humble, charming, loyal person and a man who cared about others. "He seemed to have that special charismatic personality," said Herman Cohen, U.S. assistant secretary of state for Africa from 1989 to 1993. "He became the symbol in the fight against _ ." Mandela was born on July 18, 1918. As a young man he became active in the anti-apartheid movement and joined the African National Congress, or ANC, in the 1940s. The white-led government banned the ANC in 1960, but the group continued to operate secretly. Mandela became head of the group's new military wing, coordinating a sabotage campaign against South African military and government targets. In 1962, he was arrested and put on trial for his actions and sentenced to life in prison on Robben Island off the coast of Cape Town. He spent 18 years there, refusing a government offer to release him if he would renounce the ANC's armed struggle. But he was freed in 1990 after South African President Frederik de Klerk legalized all political parties and discharged most political prisoners. Shortly after his release, Mandela was elected president of the African National Congress. And in 1994, when the ANC won South Africa's first all-race elections, he was inaugurated as the county's first black president at age 75. "Never, never and never again shall it be that this beautiful land will again experience the oppression of one by another," he said. President Mandela said he would stay for only one five-year term. Cohen says Mandela earned international respect for South Africa's national reconciliation. "Mandela devoted himself mainly to rallying the Africans to this new era to work on economic development, having good education, also he was very much of a spokesman on the international scene." he said. In 1993, Mandela shared the Nobel Peace Prize with his once bitter enemy F.W. de Klerk for their contribution to the peace process in South Africa. After receiving the award, Mandela praised the South African people. "All have created a society which recognizes that all people are born equal," he said. In a country torn apart by years of racial conflict, Nelson Mandela is considered a remarkable leader -- a man who turned South Africa away from violence and hatred into a country of greater peace and understanding.

[EX Q]: Article: No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting . For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. That many people feel their joints hurt is a sign of wet weather. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.
