The three forms
are the same
Nothing changes, so the only clues are in the rest of the sentence.
Exercises
1.a Fill in the gaps
Use the correct verb from group 1.
1.b Present or past?
These verbs look the same in the present and in the past, so look for clues. Choose PR (present) or PA (past). When you check, the word that tells you is underlined.
1.c Match the verbs to their pronunciation
Write the verb under its transcription.
Two forms
are the same
The past simple and the past participle are twins; only the base is different.
Exercises
2.a Complete the chart
2.b Fill in the gaps
Use the correct form of the verb in brackets.
2.c Sound families
Choose the vowel sound of each past form: /ɔː/ as in saw, /ɛ/ as in bed, /əʊ/ as in go, /eɪ/ as in day.
Careful: one of these words does not sound the way it looks!
2.d Circle the correct option
The three forms
are different
Three words to learn, but they travel in families: drink – drank – drunk, sing – sang – sung.
Exercises
3.a Complete the chart
3.b Fill in the gaps
Use the correct form of the verb in brackets.
3.c Follow the pattern
Each verb in a group changes like the example. Complete the other two forms.
3.d Spelling: one consonant or two?
Write the past participle of each verb. Be careful with the spelling.
Now look at your answers. Which participles have a double consonant (tt, dd)? What kind of vowel sound comes before it, short or long?
Review:
all three groups
Mix them up and see what stuck.
R.1 Which group?
1 = all the same · 2 = two the same · 3 = all different.
R.2 Odd one out
Choose the word that is different, then explain why.
R.3 Which column?
First choose 1, 2 or 3 to show which column you need. Then complete the sentence.
R.4 Find the mistake
There is one mistake in each sentence. Click it and write the correct form.
R.5 Write about the pictures
Write a sentence about each picture. Use the verb and the tense given. Checking tells you whether you used the right form; compare the rest with the model answer.
R.6 Word search
Find the past participles of these verbs. They go across (→), down (↓) or diagonally (↘). Click the first letter, then the last.
What are
irregular verbs?
Both regular and irregular forms of verbs can be traced back to Old English. There were three basic types of verb:
- Those that form the past tense by adding “-ed” to the root. E.g. watch, watched.
- Those that form the past tense by changing a vowel. E.g. give, gave.
- Wholly irregular forms. E.g. can/could, will/would, be/was.
Types 2 and 3 are referred to as irregular verbs.
The three columns
What are the three columns you find when you study irregular verbs?
The base
The infinitive without to: the word you find in the dictionary. Used after modal auxiliaries or the verbs make and let.
The simple past
Used for finished actions in the past. Regular verbs end in “-ed”.
The past participle
Used to form perfect tenses (such as the present perfect) and the passive voice.
The first one is the infinitive without to, or the base of the verb. It is the word you find in the dictionary. It is generally used after modal auxiliaries or the verbs make and let.
Of course, the same is true for the base of regular verbs.
The second one is the simple past, used for finished actions in the past.
The simple past forms of regular verbs end in “-ed”.
The third column, the past participle, is used to form perfect tenses (such as the present perfect) and the passive voice.
Perhaps because regular verbs and some irregular verbs have the same form for the simple past and the past participle, some students make the mistake of using the simple past form in the passive voice or in perfect tenses. You can’t tell the difference when the two forms are the same.
The difference between them is clear with an irregular verb that has three different forms.
So these three columns represent 1, the base of the verb; 2, the simple past; and 3, the past participle. For some irregular verbs these three forms are the same.
For some, the simple past and the past participle are the same but the base is different.
While for some verbs the three forms are different.
