1., I would like to express my concern about an increasing number of karaoke bars in the city.

2. There are a lot of reasons that I object to these places

3. Firstly, the owners take too much money from those who come / coming to sing.

4. Secondly, they cause too much noise to the neighborhood.

5. Thirdly, there are a number of pupils who play / playing truant just to go to those places to sing.

6. Last but not least, these bars do harm to the appearance of the / this city because of their too ugly flashing lights.
