\n| would<\/td>\n | must<\/td>\n | shall<\/td>\n | should<\/td>\n | ought to<\/td>\n<\/tr>\n<\/table>\n \nModal verbs are different from regular verbs in the following ways:<\/p>\n \n- ‘s’ is not used for the third person singular.<\/li>\n
- Questions are made by inversion. For example, ‘he can write’ becomes ‘can he write?’<\/li>\n
- An infinitive of another verb (without ‘to’) always directly follows a modal verb.<\/li>\n<\/ul>\n
Probability<\/strong>
\nModals are used when we need to tell how much sure we are that something has happened\/is happening\/will happen. We usually call them as modals of deduction or certainty.
\n
\nFor example:<\/p>\n\n- It’s raining, so it must be cold outside.<\/li>\n
- I don’t know where Penny is. She could have missed the flight.<\/li>\n
- This bill can’t be right. $20 for two bananas!<\/li>\n<\/ol>\n
\nAbility<\/strong>
\nSomeone\u2019s talents or abilities can be mentioned using \u201ccan\u201d and \u201ccould\u201d.
\n
\nFor example:<\/p>\n\n- He can sing in 3 languages.<\/li>\n
- My father could write very well.<\/li>\n
- I can’t run.<\/li>\n<\/ol>\n
\nObligation and Advice<\/strong>
\nVerbs like \u201cmust\u201d or \u201cshould\u201d are used to say something essential or unnecessary or to guide.
\n
\nFor example:<\/p>\n\n- Kids must play every day.<\/li>\n
- We have to wear a uniform at school.<\/li>\n
- You should stop eating sugar.<\/li>\n<\/ol>\n
\nPermission<\/strong>
\nVerbs like \u201ccan,\u201d \u201ccould\u201d and \u201cmay\u201d are mentioned when asking for, and giving permission. Modal verbs are also used to say something which is not allowed.
\n
\nFor example:<\/p>\n\n- Could I go shopping today, please?<\/li>\n
- You may not miss the class today.<\/li>\n
- Can we park the car here?<\/li>\n<\/ol>\n
\nHabits<\/strong>
\nPractices or activities we usually do or did in the past can be mentioned using \u201cwill\u201d and \u201cwould\u201d.
\n
\nFor example:<\/p>\n\n- When I lived with my family, we would often go to the park next to our home.<\/li>\n
- Ben will never eat this!<\/li>\n<\/ol>\n
\nPast modals<\/strong>
\nThe past modals having combinations like \u201ccould have with the past participle\u201d, \u201cshould have with the past participle\u201d and \u201cwould have with the past participle\u201d can be complicated. The past modal verbs \u201ccould have\u201d, \u201cshould have\u201d and \u201cwould have\u201d are all used to theoretically mention things that didn’t really happen in the past.<\/p>\nCould have with the past participle<\/strong>
\n<\/p>\n\n- \nCould have with past participle means that something was possible in the past, or somebody had the capacity to do something in the past, but it wasn\u2019t done.<\/p>\n
