Topic Sentence
The most important problem in our city is its inadequate public transportation system. Thousands of residents rely on the city’s buses
and streetcars to travel throughout this large city, but Metro Transportation
System’s daily schedules are totally unreliable. A bus or streetcar that should
arrive at 7:45 may not arrive until 8:00 or later. Moreover, it is not unusual
for a bus driver to pass up groups of people waiting for the bus, because he
wants to make up for lost time. Unfortunately, people often end up going to
work late or missing important appointments. In order for people to get to
their destinations on time, people must allow for waiting time at the bus and
streetcar stops.

5. Example 2 Topic Sentence
Topic Sentence: states the main idea of the paragraph.
Motivation
There are several possible reasons why my father is in excellent health, even though he is over seventy years of age. First, he is in excellent condition because he has stopped smoking cigarettes. He quit smoking cigarettes since whenever he climbed stairs, he would quickly stop several times and cough loudly. He also has good health as a result of stopping eating the wrong kinds of foods. For example, whereas before he would eat fatty red meat and deep-fried dishes several times a week. Nowadays he seldom does so. He is also in good physical shape, for he exercises a lot. He swims three times a week at the local gym, and on sunny days he prefers to walk home rather than take the bus. In conclusion, my father is in better shape than some of his children are!
