II. Expressing Meaning in Simple Past

 

For explanations and examples of “Be” verbs and “Do” verbs, open Unit 9 here.

 

Verb Forms in Simple Past

 

1. When “was” or “were” is the main verb, do not use a “do” verb. In the same way, when the main verb is a “do” verb, do not use “was” or “were”.

  • The Great Fire of London was a serious disaster. It was occurred in 1666.

2. Add an “ed” to the end of a regular “do” verb.

  • It destroyed a big part of London

3. After “did” in a question and negative sentence, use the base form (without -ed) since you already have a helping verb “did”.

  • How long did it last? It lasted almost five days.
  • Did it kill many people? No, it did not kill too many people. According to some reports, it killed six people.

4. “Used to + base verb” is common for past regular activities.

  • People in London used to talk about this fire in great terror[1].

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 had to 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.

 

Exercise 5. The following paragraph is about a quiz and a joke. Some sentences are correct, but others have verb tense errors. Find ten more errors and correct them (not including the example). The first one is an example.

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
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. There are fourteen more errors in the use of verb tenses in the following paragraph (not including the example). Find the errors and correct them. The first one is an example.

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.

 

Exercise 7. Choose one of the following topics to write a paragraph. Use appropriate verbs.

  1. Write a paragraph about your teenage years. What were you like? What did you like to do then? Was there anything that you had experienced in your early childhood to cause you to think or behave the way you did as a teenager?
  2. Write a letter to your spouse, child(ren), or parent(s) and reminisce[6] about your life together.
