V. Unit Review Practice
Exercise 4
In the following paragraph about learning English, some verbs are underlined. In these underlined verbs, find and correct ten more errors in the use of verbs (not including the example). The first one is an example.
A Positive Attitude
I have a positive attitude toward English grammar. When I first came to America, things are (were) different. I have never studied English before, so I am very confused about different verb forms and tenses. As time goes by, my feeling toward the language began to change. I force myself to practice even though it was hard. I write a lot, and I become more confident each time I used the language. Now, although I am more confident about grammar, I still have many problems to overcome. I find that learning a new language takes a great deal of time and that I hadto be patient and disciplined in order to be good at it. Sometimes, I was frustrated and impatient. For example, when I try very hard to include wonderful details in my paragraph, my professor and classmates may not understand some of my sentences because of many grammar mistakes. However, most times I think positively about my learning experience. I know that mistakes helped me learn. I been practicing writing with correct grammar since the beginning of this semester. I am sure that with my hard work, my skills in English will get better and better.

A Quiz and a Joke
In the reading class last week, we have (had) a vocabulary quiz. There are 20 questions about idioms. While we were taking the quiz, one of the students start to laugh loudly. We all stop to see what was going on. That student still laughed. He had forgotten that he was taking a quiz and was supposed to be quiet. Fortunately, he stopped laughing after the teacher signaled to him. After class, we all gather around him to ask why. He told us that the quiz is so easy that it reminds him of something funny:
a piece of cake on a plate
Question: Why did the students eat their test?
Answer: They ate it because their professor had told them it was a piece of cake[5]!
At the time of our quiz, he wished that the quiz would transform itself into a piece of cake because the quiz was easy for him. Upon hearing this, we were all laughing. A week had passed. I still laughed whenever I remember this incident.
Exercise 6

Childhood Memories
I am having (have) so many wonderful memories of my childhood. When I was five years old, my family move to Florida. My parents told me that we live in Chicago before we moved. For the first two years in Florida, we lived in a small apartment. Then, when it is time for my brother and me to start school, my parents were buying our first house. For the first time, I had my own room and did not had to share with my brother. I was loving that room! My mother was liking to sew, and she made beautiful quilts and matching curtains for each room. Sunday was my favorite day because we went to the beach. We use to pack a big lunch from the food that Mom buy the day before. On the beach, we kids ran, laugh, and play games. Our parents sometimes ran with us, but other times they sitting in the lawn chairs and watching us. We often did not left the beach until dark. I will always member those fun years.
