文化的背景

In many English-speaking cultures, using 'I think' is a way to practice 'hedging.' This means making a statement less forceful to remain polite and open to discussion. It reflects a cultural preference for individual opinion over absolute group consensus.

💡

The 'That' Secret

You can say 'I think that it is cold' or just 'I think it is cold.' Both are correct, but skipping 'that' sounds more natural when speaking!

⚠️

Don't be too sure

If you are 100% certain of a fact, using 'I think' might make you sound like you don't know what you're talking about. Use it for opinions, not math!

What It Means

I think is your best friend for sharing opinions. It acts like a soft cushion for your statements. Instead of saying something is a fact, you show it is your perspective. It makes you sound thoughtful and open to other ideas.

How To Use It

Put it at the start of your sentence. You can follow it with a person, a thing, or an action. For example, I think it is raining. You don't need fancy grammar here. Just say I think and then say what is on your mind. It is like opening a window into your brain.

When To Use It

Use it when you aren't 100% sure about a fact. Use it when choosing a movie with friends. It is perfect at a restaurant when deciding what to eat. Use it in meetings to offer a suggestion politely. It works great when texting to avoid sounding too bossy. Even if you are sure, it helps keep the conversation friendly.

When NOT To Use It

Avoid it if you are stating a clear, scientific fact. Don't say I think the sun is hot because everyone knows it is. If you want to sound very powerful or certain, skip it. In a crisis, people need facts, not opinions. If a building is on fire, don't say I think we should leave. Just tell them to run!

Cultural Background

English speakers value being polite and indirect. Starting with I think helps avoid direct conflict. It shows you respect that others might have different views. In places like the UK or US, being too direct can sometimes seem rude. This phrase is a social lubricant that keeps things smooth. It has been the standard way to express a thought for centuries.

Common Variations

If you want to sound more formal, try I believe. If you are just guessing, you can say I guess. For a very casual vibe, try I reckon if you are in Australia or the Southern US. You can also add that after it, like I think that..., but most people skip it. It's your all-access pass to conversation.

使い方のコツ

This phrase is extremely versatile and fits into almost any social register. The only 'gotcha' is overusing it in formal writing where you want to appear authoritative.

It is neutral! You can use it with your boss or your best friend without any problems.

Yes, you can! For example: 'It's going to rain, I think.' It sounds a bit more casual this way.

'I believe' is more formal and stronger. Use 'I think' for everyday opinions and 'I believe' for deeper convictions.

Usually, no. You just say I think it's cool without any pause or comma.

'I am thinking' usually means you are in the process of using your brain. Use I think for a finished opinion.

In academic writing, teachers often tell you to remove it to sound more objective. However, in personal essays, it is fine.

Use 'I thought.' For example: I thought the party was on Friday.

Not directly, but you can say 'Don't you think?' to ask for someone else's opinion.

'I guess' shows more doubt. Use I think when you are more confident in your opinion.

A common mistake is saying 'I think yes.' Instead, you should say I think so.

It's a habit! It fills space in a sentence and gives the speaker a moment to decide what to say next.
