Mixed Grammar Practice | English Grammar Chapter 39

Your learning path

1. LearnRead the rules and examples carefully.

2. PractiseAnswer all 15 questions before revealing the key.

3. ReviewExplain each mistake and write a new example.

Learning objectives

By the end of this lesson, you should be able to explain the rules, recognise the target forms in context, avoid common errors and apply the patterns to new sentences.

Understand the core terms and distinctions.
Use examples to connect grammar rules with real sentences.
Complete all 15 practice items before opening the answer key.

1. Switch from rule learning to diagnosis

Mixed practice deliberately combines topics. Identify the structure being tested before choosing an answer; do not assume each item tests only the chapter you studied most recently.

The quality of the answers is important, even though several answers are wrong.

2. Use elimination carefully

Remove options that violate subject agreement, verb patterns or clause grammar. Then compare the remaining options for meaning and natural usage.

She insisted on going, not insisted to go.

3. Read for context

Tense, articles and connectors often depend on the wider sentence. A grammatical form may be possible in isolation but wrong for the given timeline or meaning.

By the time the guests arrived, we had prepared dinner.

4. Review error patterns

For each wrong answer, record the rule, the cue you missed and a new example. Repeating only the correct option may not repair the underlying misunderstanding.

Rule → correction → your own example.

5. Aim for transfer

After checking the key, create a new sentence using the same rule. If you cannot explain why an option is right, revisit the relevant chapter before taking another mixed set.

Use Chapters 31–38 as targeted review.

Guided practice

Try each item first without checking the answers. Afterward, open the key and read the explanation for every uncertain answer.

Each of the machines ___ checked every morning. (is / are)
By the time the guests arrived, we ___ dinner. (prepared / had prepared)
She insisted ___ paying for lunch. (on / to)
He is ___ honest and reliable person. (a / an)
If you ___ regularly, you will improve. (practise / will practise)
The report, along with its appendices, ___ ready. (is / are)
Correct: “She suggested to take a taxi.”
___ the weather was cold, they continued the journey. (Although / Despite)
Correct: “He discussed about the issue.”
The documents ___ before the manager arrived. (had been signed / have signed)
Neither answer ___ acceptable. (is / are)
Choose: We have ___ time left, enough to review one more question. (a little / little)
The woman ___ lives next door is a doctor. (who / whom)
Correct the comma splice: “I was tired, I continued working.”

Learning reflection

I can explain the main rules in my own words.
I can recognise the correct form in a new sentence.
I can explain why a common incorrect form is wrong.
I can apply the rule without looking at the example.

Retention tip: Review your mistakes tomorrow, then again after three days and one week. Write one new example for each rule you missed.
