This grammar exercise tests your understanding of basic grammar rules. Fill in the blanks with an appropriate word or phrase.
1. If he …………………, we will be shocked.
When the verb in the if clause is in the simple present tense, we use will + infinitive in the main clause.
2. If I had known, I ………………. you straightaway.
3. ..................... seen such a mess.
When the sentence begins with a negative expression, the auxiliary verb goes before the subject.
4. I ..................... tea in the morning.
The adverb goes before the main verb.
5. He …………………. us.
6. Would you mind my ………………… the window?
7. You …………………. to find the time to do all the things you want to.
Ought is the only modal followed by a to-infinitive.
8. If you don’t want to go, you ………………..
9. You needn’t …………………. it.
When need is used as a modal auxiliary, it is followed by an infinitive without to.
10. If you asked more politely, I ............................ you some money.
When the verb in the if-clause is in the simple past tense, we use would + infinitive in the main clause.
