Hello, I'm Emma from MMM English!
「I’m too hungry to concentrate（集中注意力）.」
「You’re good enough to start a conversation（對話） in English.」
「I haven’t got enough time.」
In this lesson, you'll learn how to use these little useful words correctly in English sentences-「too」 and 「enough」. Both of these words indicate（表示） a degree.
They give us more information about an adjective（形容詞）, or an adverb（動詞）, or a noun（名詞）. 「I’m too hungry to concentrate.」So, here 'too' means that it is more than what is wanted or what is needed. So, it's usually a negative thing! 「You are more hungry than you want to be!」This is really frustrating（讓人抓狂的） for you, because you can't concentrate! 「I’m too hungry to concentrate.」 「You’re good enough to start a conversation in English.」
So here, 'enough' tell us that it is the amount that we want or we need. It’s the right amount, and this is a positive（正面的，積極的） thing! You have what is needed, you are good enough. 「You are not good enough.」Ouch! That is really mean! Not enough means that it is less than the amount that you want or you need. It's a really negative thing. It's a pretty mean thing to say. - 「You’re not good enough.」
So, let's look at the structures（結構） for each of these words with adjectives and adverbs first. So, 'too' comes before an adjective or an adverb. 「He is driving too fast.」「You’re speaking too quickly for me. 」 「He’s too old to drive.」
Remember that using 'too' with an adjective or an adverb usually suggests that it's a negative（負面的，消極的） thing. It's more than what is wanted or needed. So, it's not correct to say that the movie was 'too good' when you really enjoyed it! It's also not correct to say that your friend is 'too funny'. It sounds really strange to native English speakers, because it suggests that it's more than what you want or what you need it to be. Use 『really』 or 'very' or 'so' instead. 「Your friend is so funny.」 「The movie was really good.」 That sounds better!
There are some exceptions（例外） to this though, when you're speaking colloquially（口語化的）- especially in Australia where I'm from! Like... For example, if someone asked me, "How are you?" I'd probably say, "Not too bad." This is really common in Australia and it means 『good』, but that's an exception.
Okay, what about 'enough'?
'Enough' comes after the adjective or the adverb. 「I am strong enough to lift those boxes.」「It’s warm enough to go for a swim.」「He is entertaining（有趣的） enough to perform on stage.」「You’re here often enough; you might as well live here.」Now, what about when 'enough' is used in a negative sentence?'Enough' comes after the adjective or the adverb, but 'not' comes before. 「I am strong enough to lift those boxes.」 And this has the same meaning as-I'm too weak. 「It’s warm enough to go for a swim.」 ... which means 『it’s too cold』.
You can also use 'too' and 'enough' with nouns. Use 「too」 with 『much』 or 『many 『and noun. So again, this means that we have more of the noun than we want or we need. You would choose 'many', if the noun was countable（可數的）. And you would choose 'much', if the noun was uncountable（不可數的）. 「There are too many people here.」「Paul has too much furniture in this room.」「I』ve got too many options（選項，選擇） that I cannot decide.」「You can never give too much advice.」Now, if you are not sure about which nouns are countable and which are uncountable, you should check out this lesson right here, because I'll explain it for you there!
So, what about 'enough'? Well, with a noun 'enough' comes before the noun. Again, this means that we have the right amount, the amount that we want and that we need. 「I have enough time.」「There are enough seats in the car, you should come.」「We have enough money, let’s buy it.」And to make these sentences negative we add 'not' - usually before the main verb. 「I haven’t enough time.」「She didn’t earn enough money.」「We haven’t made enough food.」「There are not enough people here.」The 'be' verb is a bit of an exception here, to the rule. The structure is a little different.
When the 'be' verb is the main verb, then 'not' comes after the main verb. So, these handy little words will definitely help you to express yourself more clearly in English. And now you know exactly how to use them correctly. Make sure you practice them. Write some examples if you want, add them in the comments（評論） below!
Remember that 'too' means that it's more than the necessary amount. 'Enough' is the necessary amount, it's the exact amount. And 'not enough' is less than the necessary amount.
