Study English

You will see for each tense:
- Structure
- Examples
- When do we use it?

Verb Forms
Before we start, look at the main forms of the verb study:

Why Use One Sentence to Learn All 12 Tenses?
When you use the same main idea in every tense, you stop focusing on too many different meanings and start noticing the grammar pattern.
That means you can compare:
- I study English
- I am studying English
- I have studied English
- I have been studying English
This makes tense learning more visual, organized, and much easier to remember.

Quick comparison of the 12 tenses
Present
- I study English.
- I am studying English.
- I have studied English.
- I have been studying English.
Past
- I studied English.
- I was studying English.
- I had studied English.
- I had been studying English.
Future
- I will study English.
- I will be studying English.
- I will have studied English.

What about the gerund?
The gerund uses the -ing form of the verb as a noun.
With our verb, the gerund is:
studying
Example
Studying English is important.
Here, studying English is the subject of the sentence, so it works like a noun.
Important note
The -ing form can have two jobs:
- As part of a continuous tense
- I am studying English. (Here, studying is part of the verb phrase.)
- As a gerund
- Studying English helps me communicate better. (Here, studying is a noun-like word.)
So, the form is the same, but the function is different.
A simple summary of the 12 tenses

Answers and explanations
Exercise 2 Answers
1. A) do not study English
Why: For negative sentences in the present simple, we use do not + base verb.
2. B) am not studying English
Why: “Right now” needs the present continuous, and the negative form is am not + verb-ing.
3. C) did not study English
Why: In the past simple negative, we use did not + base verb, not “studied.”
4. A) had not studied English
Why: “Before the class started” shows one action earlier than another past action, so we use the past perfect.
5. A) will not have studied English
Why: This is the negative form of the future perfect: will not have + past participle.
Exercise 3 Answers
1. B) Do I study English every day?
Why: Questions in the present simple use do + subject + base verb.
2. B) Am I studying English now?
Why: Questions in the present continuous use am/is/are + subject + verb-ing.
3. B) Have I studied English already?
Why: “Already” often fits the present perfect when the action matters now.
4. B) Had I studied English before I moved to Canada?
Why: This sentence compares two past actions. The earlier one uses the past perfect.
5. A) Will I have been studying English for a year by July?
Why: This question asks about duration continuing up to a future point, so it needs the future perfect continuous.
Exercise 4 Answers
1. A) I study English.
Why: “Every day after dinner” shows routine, so we use the present simple.
2. B) I am studying English
Why: “Listen!” and “right now” show something happening at the moment, so the present continuous is correct.
3. B) I was studying English
Why: This shows an action in progress when another past action happened, so we use the past continuous.
4. B) I will have studied English
Why: “By the time the exam starts tomorrow” means the action will be finished before a future point, so we use the future perfect.
5. A) I have been studying English
Why: The action started in the past and still continues now, so we use the present perfect continuous.
Exercise 5 Answers
1. B) studying English
Why: After enjoy, we usually use a gerund.
2. B) Studying English
Why: Here the verb is acting like a noun and is the subject of the sentence, so we use the gerund.
3. B) studying English
Why: After the preposition before, English commonly uses the -ing form.
4. A) am studying English
Why: This is not a gerund. It is the present continuous, which needs am + verb-ing.
5. A) studying English
Why: After love, we commonly use the gerund in this kind of sentence.
Learning all 12 English tenses can feel difficult at first, but it becomes much easier when you use one main idea and compare the forms step by step.
With study English, you can clearly see how English changes in:
- the present
- the past
- the future
- simple, continuous, perfect, and perfect continuous forms
You also saw that studying can be:
- Part of a tense, as in I am studying English
- a gerund, as in Studying English is important
The key is to notice time and purpose:
- Is it a habit?
- Is it happening now?
- Is it finished?
- Did it continue for some time?
- Does it connect to the present, past, or future?
When you practice this way, grammar stops being just rules and starts becoming a pattern you can recognize and use.
