Example Text 1

Cats make better pets then dogs. There are a couple reasons why cats are better. Cats do not require as much attention as dogs. My first dog would follow me around the house and constantly jump on me until I pat him. When I got a cat, there were times when I only saw her during feeding. In addition to needing attention, dogs are also more expensive. Dogs require obedience school which costs hundreds of dollars, and dogs also have the tendency to destroy household objects. Because of the high cost and elevated needs of dogs, cats are a better option when considering a pet.

Example Text 2

My house and my car are similar in many ways. First of all, both places are untidy. In my house, you can see clothes strewn on chairs, papers littering all surfaces, and dishes in the sink. Similarly, in my car, the back seat and floor are covered with sports clothes and shoes, books, empty soft-drink cans, and gum wrappers. Second of all, I like to spend a lot of time in my house and in my car. After work, I usually go home, eat dinner, and flop down onto the sofa to watch videos or read a book. Likewise, on weekends, I usually take long out-of-town trips in my car; sometimes I even sleep in it to save money on hotels. Finally, I do some identical activities in my house and in my car. In my house, I get dressed, listen to loud music, and eat. In the same way, I change into my sports clothes in the car, listen to loud music on my car stereo, and eat snacks on my way home after work or the gym. Although I treat my home and my car alike, I should probably clean both of them up, so that people won’t be afraid to visit or drive with me!
