Part Three Editing / Grammar Skills
Unit 15 Modals
- To understand what modals are and what principles they follow
- To learn the challenges and strategies in using appropriate modals
- To learn the meanings and uses of modals and modal-like expressions through multiple examples
- To practice using modals through a variety of writing situations
The following ten sentences are about some customs from different countries. The modal and main verb are bold-faced in each sentence. If the bold-faced part is correct, choose “correct”. If not, choose the other answer. After you finish one sentence, you will get instant feedback on your answer before the next sentence. If you make mistakes, you can retry all the questions or see all the answers at the end of the pre-test.
II. Principles of Using Modals
As you have learned in Unit 9 Verb Basics in Academic Writing (Open Unit 9 here), modals are an important part of the verb family. They are considered helping verbs, also called auxiliary verbs. Most modals follow the following principles:
1. They cannot exist by themselves. They are followed by the base form of main verbs to show different meanings and tones.
modal + base form of main verb = complete verb
- In the United States, people should call ahead before visiting someone. (no “calls, called, calling, to call”)
- People must not show the “OK” gesture with the thumb and index finger in Mexico. (no “shows, showed, showing, to show”)
2. Contractions are common are in modals, such as “shouldn’t” and “mustn’t”. However, “may” and “might” do not have a contraction form. It is wrong to write “mayn’t” and “mightn’t”.
- Small children
mayn’t stay(may not stay) alone at home in the United States.
mightn’t be(might not be) a good idea for children to stay in their friend’s home overnight.
3. Some expressions are called modal-like expressions. There is a “to” in them, and the base form of the verb follows the “to”. These expressions include: be able to, be supposed to, have to, have got to, ought to, and some others.
- People have to come on time for an appointment in the United States.
- They are supposed to explain the reasons if they are late.
4. Some modals and modal-like expressions are often used in conversations only.
- In Thailand, people had better not touch the head of a statue.
- In the U.S. restaurants, customers have got to tip the waiters and waitresses.
Exercise 1. The following sentences are about dining customs in some countries. There are mistakes in the form of modals and main verbs. Identify each mistake by underlining the whole verb (modal + main verb) and then correct the mistake. If the main verb is missing, add it.
can to learn (can learn) about different customs and traditions when they travel abroad.
- Dinning traditions may the most interesting to most people.
- In Kenya, guests should to wash their hands both before and after the meal. They cannot sitting with their feet and toes pointing toward any of the other guests or the food. Kenyans do not use utensils. They eat with their right hand. They must not to use their left hand during the whole meal.
- Americans and Europeans have opposite dinning etiquettes. Americans should holds the knife in their right hand and the fork in their left hand, but the Europeans are suppose to hold the knife in their left hand and the fork in their right hand.
- People in Morocco practice communal eating. This means that they eat from the communal bowl closest to them. A person must eats using his or her right hand. The left hand mayn’t be used to get food. If a bone is taken, the person supposed to suck the marrow from it.
III. Challenges in Learning Modals and the Strategies in Using Them
1. The same modal may have different meanings in different contexts.
- I can drive a car because I have a driver’s license. (permission)
- I can drive a car because I know how to drive. (ability)
2. The same meaning can be expressed with different modals, but the tone or level of strength is different.
- In order to drive in the U.S, a person must have a driver’s license. (stronger)
- In order to drive in the U.S, a person has to have a driver’s license. (less strong)
3. Some modals have the appearance of past tense, but they have a present or future meaning.
- Most cultural traditions stay for generations, but some might change quickly.
- People had better learn the customs of another country when they travel there.
1. Understand a modal, its meaning, its time (past, present, future), and its form together as a “package”.
- In many countries in the past, young people had to follow the custom of the arranged marriage.
- In some countries nowadays and in the near future, some young people still must follow the custom of the arranged marriage.
In both sentences, “had to follow” and “must follow” have the same meaning: obligation, responsibility, necessity.
However, the first sentence shows the meaning in the past, and its form is “had to + follow”.
In the second sentence, the same meaning is expressed in present and future sense, and its form is “must + follow”.
Therefore, try not to study modals in isolation. Instead, understand them in the context and study the “package”.
2. Use the same strategy as in learning other aspects of English: practice, practice, and practice.
IV. Uses of Modals and Modal-Like Expressions

After you finish reading and understanding the first three paragraphs, write a new supporting paragraph about a person you know who spent last summer vacationing and relaxing. Then write a conclusion for the essay. Include at least five modals and modal-like expressions. You may write in the box below or in your own notebook. (Warning: Once you leave this page, you will lose what you have written in the box.)
How to Spend the Summer?
High school students in different countries may spend (possibility, present) their summer very differently. Some might value life experiences by working on a job, some could use the time catching up with their academic work, and others might consider it an opportunity to relax and have fun. How they spend their summer might reflect some of the customs and values of their cultures.
It is common for many high school students in the United States to work during the summer months. They could work in any type of job: food, travel, secretarial, health care, summer camp, and many others. Last summer, Joan worked as a summer camp activity leader. She was happy that the job provided her with valuable work experience as well as a small income. Both the experience and the money should be helpful in her future college study.
In Korea, however, it is not usual for high school students to hold a job in summer. They are supposed to take extra classes to prepare for university. Last summer, Ji-hoon kept himself busy by taking a few science and English classes in a cram school. Though he was very busy, he had to do so. He was determined to be better prepared for his university entrance exam.
Exercise 9. Choose two of the following topics and write a paragraph for each. Use proper modals.
- Describe one of the holiday dinning traditions in your native country.
- Describe some customs about naming a baby in your native country.
- Explain one of the taboos for a wedding ceremony in your native country.
- Some people say that elderly parents should live with their adult children. Do you agree or disagree? Why do you think so?

- Write about the joys and challenges of living in two cultures (your native culture and the American culture). What was your biggest cultural shock during your first two weeks in the U.S.?
Go to The NSNT Free Writing Approach and Additional Weekly Prompts for Writing in Appendix A. (Open Appendix A here.) Choose two topics that involve modals. You may start with the NSNT approach. Then revise and edit your paragraphs. Pay attention to the use of modals. You are encouraged to share your writing with your partner and help each other improve.
The words here have appeared in this unit. The best way to learn them is to guess the meaning of each word from the context. Then hover your computer mouse over the number beside each word to check its meaning and part of speech. These words are also listed in the footnote area at the end of each unit.
Here, you can use the flashcards below to review these words.
- Modals are helping verbs (also called auxiliary verbs). They must be used with a main verb to serve as the complete verb in a sentence: Modal + Main Verb = Complete Verb
- A modal is followed by the base form of the main verb.
- The same modals may mean differently in different contexts, and some others may share similar meanings but have differences in tone and level of emphasis.
- Some modals have their unique forms of past tense. Some of them look like the past tense but mean present or future.
- Do not use “mayn’t” and “mightn’t”.
- A good strategy is to understand modals is by learning each modal, its meaning, its time reference, and its form together as a “package”.
