6. Haste is waste.

7. Regular exercise is one of the essentials of good health.


(Have the repetitions really made the idea of the topic sentence clearer
or more emphatic or more definite? What other methods of development have
you used?)


+51. Development by a Combination of Methods.+--A paragraph should have
unity of thought, and, so long as this unity of thought is kept, it does
not matter what methods of development are used. A dozen paragraphs taken
at random will show that combinations are very frequent. Often it will be
difficult to determine just how a paragraph has been developed. In
general, however, it may be said that an indiscriminate mixture of methods
is confusing and interferes with unity of thought. If more than one is
used, it requires skillful handling to maintain such a relation between
them that both contribute to the clear and emphatic statement of the main
thought.

The paragraph from Dryer, page 74, shows a combination of cause and effect
with specific illustrations; that from Wolstan Dixey, page 81, shows a
combination of repetition with specific instances.
