               II.     SENTENCE PRACTICE:       Oral Exercises

                       NOTE:      Written sentences tend to be longer and more complicated than spoken
                                  sentences. Since they are printed the reader can re-read them several times
                                  If he has difficulty in understanding them. When sentences are spoken the
                                  listener usually only has one chance to hear the sentences. Written sentences
                                  can be changed to spoken sentences by making them into a number of shorter
                                 simpler sentences.


                       Use the examples below as a guide to change the following written sentences to
                       spoken sentences.
                       Examples:

                       Written:     The thunderstorm is a local storm which is produced
                                     by a cumulonimbus cloud and is always accompanied

                                     by thunder and lightning.
                        Spoken:    A thunderstorm is a local storm.
                                    It's produced by a cumulonimbus cloud.

                                    It's always accompanied by thunder and lightning.
                        Written:   The pilot's judgement of turbulence severity may be influenced by the
                                    length of time his plane 18 exposed to turbulence, the amount of
                                    experience the pilot has and the type of aircraft he is flying.
                        Spoken:    The pilot's judgement of turbulence severity may be influenced by three
                                    things.

                                    It is influenced by the length of time his plane is exposed to turbulence
                                    It is influenced  by the amount of experience he has. It is influenced by the
                                    type of aircraft he is flying.
                       a. The upward moving air rises faster and faster until it reaches a height where the
                            temperature of the rising air is cooled to the same temperature of the surrounding
                            air.

                       b.  An object placed in any moving air current disturbs the flow by causing the wind to
                             change direction of flow to go over or around the object.


                       c.   Mechanical turbulence is caused by obstructions in the path of the wind and is not
                             caused by meteorological processes in the air ma88 itself.

                       d.  The landing area may be safely upwind from an obstruction when an east wind is
                             blowing and yet be a turbulent area because it is downward from the same obstacle
                             when a west wind is blowing.
