IV/PHẦN ĐỌC HIỂU According to the controversial sunspot theory, great storms on the surface of the sun hurl streams of solar particles into atmosphere, causing a shift in the weather on earth. A typical sunspot consists of a dark central umbra surrounded by a lighter penumbra of light and dark threads extending out from the centre like the spokes of a wheel. Actually, the sunspot are cooler than the rest of the photosphere, which may account for their color. Typically, the temperature in a sunspot umbra is about is about 4000 K and the granules outside the spot are 6000 K. Sunspots range in size from tiny granules to complex structures with areas stretching for billions of square miles. About 5% of the spots are large enough so that they can be seen without instruments; consequently, observations of sunspots have been recorded for several thousand years. Sunspots have been observed in arrangements of one to more than one hundred spots, but they tend to occur in pairs. There is also a marked tendency for the two spots of a pair to have opposite magnetic polarities. Furthermore, the strength of the magnetic field associated with any given sunspot is closely related to the spot’s size. Although there is no theory that completely explains the nature and function of sunspots, several models attempt to relate the phenomenon to magnetic field along the lines of longitude from the north and south poles of the sun. 56.

Signals, signs, symbols and gesture may be found in every known culture. The basic function of a signal is to impinge on the environment in such a way that attracts attention, as, for example, the dots and the dashes of a telegraph circuit. coded to refer to speech, the potential for communication is very great. Less adaptable to the codification of word, signs also contain meaning in and of themselves. A stop sign or a barber pole conveys meaning quickly and conveniently. Symbols are more difficult to describe than either signals or signs because of their intricate relationship with the receiver’s cultural perceptions. In some culture, applauding in a theatre provides performers with an auditory symbols of approval. Gestures such as waving and handshaking also communicate certain cultural messages. Although signals, signs, symbols and gestures are very useful, they do have a major disadvantage. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. As a result, means of communication intended to be used for long distances and extended periods are based upon speech. Radio, TV and the telephone are only a few. 1.
