(1)PRETEST I Read the passage and choose the best answer:
Although speech is the most advanced form of communication, there are many ways of communicating without using speech Signals, signs, symbols, and gestures may be found in every known culture The main function of a signal is to impinge upon the environment in such a way that it attracts attention, as for example, the dots and dashes of a telegraph circuit Coded to refer to speech, the b codification potential for communication is very great Less adaptable to the codification of words, signs also contain meaning in and of themselves A stop sign or a barber pole conveys meaning quickly and more difficult to describe than either signals or signs because of their intricate relationship with the receiver's cultural perceptions In some cultures, applauding in a theatre provides performers with an auditory symbol of approval Gestures such as waving and handshaking also communicate certain cultural messages
Although signals, signs, symbols, and gestures are very useful, they have a major disadvantage They usually 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 on speech. Radio, television, and the telephone are only a few
1 Which of the following would be the best title for the passage?
A Signs, Signals, and Symbols B Gestures C Communication D Speech What does the author say about speech?
A That it is the only true form of communication B That it is dependent upon the advances made by inventors C That it is necessary for communication to occur D That it is the most advanced form of communication Applauding was cited as an example of
A a sign B a signal C a symbol D a gesture Why were the telephone, radio, and TV-Invented?
A Because people were unable to understand signs, symbols, and signals B Because people wanted to communicate across long distances
C Because people believed that signals, and symbols were obsolete D Because people wanted new forms of entertainment
5 It may be concluded from this passage that
A signals, signs, symbols, and gestures are forms of communication B symbols are very easy to define and interpret
C only some cultures have signals and symbols D waving and handshaking are not related to culture II Read the passage and answer following questions:
Weather is created by the heat of the sun When the sun shines on the earth, the air close to the surface heats up, expands and rises The higher it goes, the cooler it becomes Meanwhile, an area of warmer, low-pressure air forms below it Winds are caused by air moving from an area of high pressure to one of low pressure The closer the pressure centers are to each other, and the greater the pressure difference between them, the stronger the wind will be
High and low-pressure air masses travel the globe and cause major weather changes When a cold, high-pressure polar air mass meets an extremely low-high-pressure tropical air mass, their combination can produce intense storms such as typhoons, hurricanes, and tornados Less severe weather conditions are often caused by small, local, pressure areas A mild rain storm occurs when rising warm air combines with cool air Clouds are created as the moist warm air cools and condenses to form water droplets When clouds reach a saturation point, or the point at which they can no longer contain their moisture, the droplets fall to earth as rain or snow
Weather forecasters look at the movement of warm and cold air masses and try to predict how they will behave Although weather forecasting is not completely accurate, satellites, sophisticated instruments, and
computers make weather prediction far more accurate today than in the past The advantages of weather prediction are numerous, but in the end, nature does whatever it pleases We may attempt to predict weather but we cannot control it
What causes the wind to become stronger?
What are typhoons, hurricanes and tornados caused by? When does a mild rain storm take place?
(2)Why is weather prediction today much more accurate than in the past? IV Use correct forms of the words in parentheses:
