How to reduce the degree of discomfort while in foreign countries？
It is, everyone agrees, a huge task that the child performs when he learns to speak, and the fact that he does so in so short a period of time challenges explanation.
Language learning begins with【C1】______. Individual children【C2】______greatly in the amount of listening they do before they start speaking, and【C3】______starters are often long listeners. Most children will "obey" spoken【C4】______some time before they can speak, though the word obey is hardly【C5】______as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by【C6】______and by making questioning noises.
Any【C7】______to trace the development from the noises babies【C8】______to their first spoken words leads to【C9】______difficulties. It is【C10】______that they enjoy making noises, and that during the first few months one or two noises【C11】______themselves out as particularly【C12】______of delight, distress, sociability, and so on. But since these cannot be said to show the baby's intention to【C13】______, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they【C14】______with sounds for enjoyment, and【C15】______by six months they are able to add new sounds to their【C16】______. This self-imitation leads on to【C17】______imitation of sounds made or words spoken to them【C18】______other people. The problem then【C19】______as to the point at【C20】______one can say that these imitations can be considered as speech.
【C1】
听力原文： The Antarctic is probably the most difficult place on earth for human beings to survive. For six months of the year there is total darkness, and temperatures may fall as law as -88~C. Even in the summer months the temperature is often below zero.
The first successful expedition to the South Pole was led by Ronald Amundsen. His team used dogs and sledges to cress the frozen continent, and reached the pole in December 1911. in 1928, Richard Byrd decided to lead an expedition to the Antarctic to explore the unknown area from the air for the first time. It was the largest and best equipped expedition that had ever set out for the Antarctic. Byrd and his team established a base which they called Little America on the coast of the Rosa Sea. In November 1929, during the Antarctic spring, Byrd and three colleagues flew from the Little America base to the South Pole and back in 19 hours.
Byrd's major achievement was to introduce the use of aircraft ,radio and other devices in polar exploration. He did not agree with Ronald Amundsen that the airplanes would one day replace dogs and sledges; he believed that modern techniques were only an addition to the traditional methods of exploration. All of his expeditions, therefore, carded dogs and sledges, and people to look after them. This proved very efficient, and Byrd was able to achieve results of great scientific value.
What is the lowest temperature in the Antarctic？
How long did it take Byrd and his colleagues to fly from Little America to the South Pole
