Overview

Learning to talk about what’s coming next is a huge step in becoming a more confident English speaker. This chapter is all about giving you the tools to share your future plans and make fun suggestions, moving you smoothly into more advanced conversations. As an A2 English grammar learner, you’re ready to start using phrases like going to to discuss your intentions and express simple predictions.
Imagine being able to tell a new friend about your weekend plans or what you hope to do next year! This is where English looking ahead: plans and suggestions really comes to life.
You’ll also discover how to use will for those spontaneous decisions or quick guesses about the future. And for those moments when you want to invite others to join in, mastering "Let's" for suggestions will make your interactions much more engaging. This guide will help you connect your current thoughts to future actions, ensuring you can participate in everyday chats about what's happening soon.
Get ready to express your exciting plans and ideas with confidence!

How This Grammar Works

Talking about the future in English primarily uses two main structures: going to and will, each with its own specific use. We also have a fantastic, friendly way to make suggestions: "Let's." Let's break them down.
First, going to is your go-to (pun intended!) for discussing plans and intentions that you’ve already thought about. When you say,
I am going to visit my parents next month,
it shows this is a pre-arranged plan, not a sudden idea. It also works for predictions based on current evidence: "Look at those dark clouds!
It is going to rain.
You can see the signs now. Remember, it’s always
be" (am, is, are) + going to + base verb.
Next, we use will for spontaneous decisions made at the moment of speaking or for general predictions and promises without strong current evidence. For instance, if someone asks,
What would you like to drink?
and you haven't thought about it, you might say,
I will have a coffee, please.
This is a quick decision. You also use will for simple predictions or promises:
I think it will be sunny tomorrow
or
I promise I will help you.
Finally, for making suggestions and inviting others to join an activity, we use "Let's.
This is a concise and friendly way to say
Let us.
It’s always followed by the base form of the verb:
Let's go to the park! or Let's watch a movie tonight." It’s perfect for social situations and showing you want to do something together. Understanding these differences is key for clear communication about A2 English grammar futures.

Common Mistakes

  1. 1✗ We are going to going to the beach.
✓ We are going to go to the beach.
*Explanation:* The to in going to is part of the structure for future plans, it's not the verb to go. You still need the main verb after it.
  1. 1✗ I will study for the exam, I already bought the books.
✓ I am going to study for the exam, I already bought the books.
*Explanation:* Buying the books shows a prior plan or intention. Will would imply a sudden decision or a general prediction without this evidence.
  1. 1✗ Let's to eat something.
Let's eat something.
*Explanation:* "Let's
is followed directly by the base form of the verb, without
to."

Quick FAQ

Q

When should I use going to instead of will for predictions?

Use going to when your prediction is based on something you can see or feel now, like "It's so cloudy, it's going to rain.

Use
will
for general predictions or guesses without current evidence, such as
I think it will be a good year."

Q

Is "Let's" always polite?

Yes, "Let's

is generally a polite and inclusive way to make a suggestion. It implies
we should or we could," inviting others to join in a friendly manner.

Q

Can I use will for plans too?

While you sometimes hear "I'll go to the shop later,

it often implies a less firm or more spontaneous decision than
I'm going to go to the shop later,
which suggests a settled plan. For firm plans,
going to" is clearer.

Q

Are these structures used in both speaking and writing?

Absolutely! These structures for English looking ahead: plans and suggestions are fundamental for both spoken and written communication at the A2 level and beyond.

Cultural Context

Native English speakers fluidly switch between will and going to depending on the context of spontaneity versus pre-planning. You’ll find going to is very common in everyday conversation for discussing weekend plans or intentions. Will pops up often for offers, promises, and instant decisions.
"Let's" is universally friendly and commonly used across all informal social situations, from suggesting a movie to proposing a new project. There are no significant regional differences in the core usage of these forms; they are standard across all English-speaking countries.

正解: I am going to swim.

After 'Let's', use the base form of the verb without 'to'.

Wrong: Let's to go.
正解: Let's go.

Modal verbs like 'will' are followed by the base verb directly. Do not use 'to'.

Wrong: I will to see you.
正解: I will see you.

よくある質問 (6)

「going to」は、すでに決めた計画や、現在の証拠に基づいた予測に使います。「will」は、その場で決めたこと、約束、または特定の証拠がない一般的な予測によく使われます。「going to」は「事前に決めたこと」、「will」は「今決めたこと」と考えるといいでしょう。
はい、もちろんです!期間よりも意図が重要です。例えば、「I'm going to retire in 20 years」(長期計画)や「I'm going to grab a coffee in 5 minutes」(短期計画)のように言えます。計画が存在することがポイントです。
「will」を使った肯定文の基本的な形は「主語 + will + 動詞の原形」です。例えば、「I will eat」や「She will study」のように使います。
否定文を作るには、「主語 + will not + 動詞の原形」を使います。短縮形の「won't」が一般的で、「I won't go」や「They won't come」のように言います。
日常会話では普通使いません。「I will go to the gym tomorrow」と言うと、決まった予定を述べるよりも、自分自身に約束しているように聞こえます。計画には「going to」を使いましょう。
はい、正しいですが、少し繰り返しに聞こえます。ネイティブスピーカーは、「I'm going to the store」(現在進行形)のように言うことが多いです。「I'm going to go to the store」
