Summary of Essential English Grammar and Vocabulary

## Introduction This study guide explains the main ways we talk about the future in English: **be going to**, **present continuous**, and **will / won’t / shall**. You will learn when to use each form, see clear examples, and practise with typical situations. > **Definition:** Future forms are verb structures we use to talk about plans, intentions, arrangements, predictions, promises, offers and instant decisions about things that will happen later. ## Overview of the three main future forms We use three common structures to talk about different kinds of future meaning: | Form | Use | Example | |---|---|---| | **be going to + infinitive** | Plans and intentions already decided; predictions when there is evidence | My sister's going to adopt a child. Look at those clouds — it’s going to rain. | | **Present continuous (be + verb-ing)** | Fixed future arrangements with time/place already arranged | We’re meeting at 10:00 tomorrow. Jane’s leaving on Friday. | | **will / won’t / shall + infinitive** | Instant decisions, promises, offers, predictions, future facts, suggestions (shall with I/we in questions) | I’ll carry that bag. I won’t tell anyone. Shall we eat out tonight? | > **Definition:** An arrangement is a plan with a fixed time or place (for example, a booked event or a scheduled meeting). ## be going to + infinitive ### Uses - **Plans and intentions** — when someone has already decided to do something. - Example: My sister’s going to adopt a child. (Not: My sister will adopt a child.) - **Predictions with evidence** — when we can see signs that something will happen. - Example: Look at those black clouds. It’s going to rain. ### Notes - Use *be going to* rather than *will* when a decision has already been made. ## Present continuous (be + verb-ing) ### Uses - **Future arrangements** — when the time and place are decided (often booked). - Example: We’re getting married on October 12th. (Emphasises arrangements like a booked church.) - Common with travel verbs: go, come, arrive, leave. - Example: He’s arriving tomorrow and leaving on Thursday. ### Comparison with be going to - Both can express plans and arrangements. Differences: - **be going to**: shows a decision has been made (general plan). - **present continuous**: emphasises arranged details (time/place booked). > Fun fact: Many native speakers use both forms interchangeably for plans, so context often decides which is more natural. ## will / won’t / shall + infinitive ### Uses - **Instant decisions**: choose something at the moment of speaking. - Example: I’ll have the steak. (Deciding at the table.) - **Promises**: assure someone about future behaviour. - Example: I won’t tell anybody where you are. - **Offers**: volunteer help. - Example: I’ll carry that bag for you. - **Predictions and future facts**: things we think will happen or are fixed by calendars. - Example: You’ll love New York! Next year Christmas Day will be on a Thursday. - **Shall**: with *I* and *we* in questions for offers/suggestions. - Example: Shall I help you with your homework? Shall we eat out tonight? ### Notes - Use *will/won’t* (not present simple) for promises, instant decisions and offers. - Use *shall* (not *will*) in formal or polite questions with *I* or *we*. ## Quick reference table | Situation | Use | Example | |---|---|---| | Decided plan (already decided) | be going to | I’m going to study law. | | Arranged plan (time/place fixed) | Present continuous | I’m seeing the dentist at 3pm. | | Instant decision / offer / promise | will / won’t | I’ll help you now. I won’t tell. | | Prediction with evidence | be going to | That tree is bending — it’s going to fall. | | Prediction without direct evidence / opinion | will | I think she will pass the exam. | ## Practice: common sentences and corrections - We use **be going to** (NOT *will/won’t*) when an action is already decided. Wrong: *My sister will adopt a child.* - We use **be going to** for predictio
