Used to do

We use 'used to' for something that happened regularly in the past but no longer happens.

· I used to smoke a packet a day but I stopped two years ago.

· Ben used to travel a lot in his job but now, since his promotion, he doesn't.

· I used to drive to work but now I take the bus.

We also use it for something that was true but no longer is.

· There used to be a cinema in the town but now there isn't.

· She used to have really long hair but she's had it all cut off.

· I didn't use to like him but now I do.

'Used to do' is different from 'to be used to doing' and 'to get used to doing'

to be used to doing

We use 'to be used to doing' to say that something is normal, not unusual.

· I'm used to living on my own. I've done it for quite a long time.

· Hans has lived in England for over a year so he is used to driving on the left now.

· They've always lived in hot countries so they aren't used to the cold weather here.

to get used to doing

We use 'to get used to doing' to talk about the process of something becoming normal for us.

· I didn't understand the accent when I first moved here but I quickly got used to it.

· She has started working nights and is still getting used to sleeping during the day.

· I have always lived in the country but now I'm beginning to get used to living in the city.


O presente perfeito é marcado pela forma:

Sujeito + have/has + verbo principal no particípio + complemento.
Susan has been to England. (Susan esteve na Inglaterra).

O presente perfeito pode ser usado para indicar:

1- Ações que começaram no passado e continuam até o presente.

She has worked at the hospital since April. (Ela trabalha/ tem trabalhado no hospital desde abril).
I have exercised at the gym lately. (Eu tenho me exercitado na academia ultimamente).
They have organized their wedding. (Eles têm organizado o casamento deles).

2- Ações que ocorreram em um tempo não determinado (indefinido) no passado.

I have been to the U.S.A. (Eu estive nos E.U.A.)
She has traveled to England. (Ela viajou para a Inglaterra).
You have made a delicious apple pie. (Você fez uma torta de maçã deliciosa).

3- Ações que acabaram de acontecer.

They have just left. (Eles acabaram de sair).
Jane has just made the lunch. (Jane acabou de preparar o almoço).
I have just done the dishes. (Acabei de lavar a louça).

Para as frases negativas, basta acrescentar o “not” após “have/has”. E nas frases interrogativas, basta colocar o “have/has” no início da frase.

Modal verbs can, may, must - grammar rules
We use the modal verbs can, may, must in the English language for various meanings - ability, possiblity, probability, permission, attitude, opinion, speculation, etc.
CAN
1. It is used to express the ability to do something.
I can swim very well.
Can he can speak English fluently? - No, he can't.
We cannot sing at all!
2. It expresses the possibility to do something.
We can go to the seaside at last. Our holidays start next week.
3. We use it to say that something is probable.
It can be John. He has blond hair and he is wearing glasses.
4. It expresses the permission to do something.
Why not? You can marry her. She is a nice girl.
MAY
1. It is used for permissions.
You may borrow my car. I won't need it.
May I smoke here? - No, you can't, I'm sorry.
2. It is used to express probability or prediction.
They may call tomorrow. I hope so.
The main difference between may and can is in style. May is more formal than can. Can is typical of spoken English.
3. The opposite of may is must not or may not.
May I smoke here?
- You mustn't smoke here. (strong prohibition)
- You may not smoke here. (more polite, very formal)
- You can't smoke here. (informal spoken English)
MUST
1. It is used for strong obligations. It is personal, because it expresses the speaker's opinion or will.
I must clean my teeth. I want to be healthy.
You must go there. And do it right now!
2. It means a strong recommendation.
You must see it. It's the best film I've ever seen.
3. We use it to show the certainty of the speaker.
They must be at school by now. It's already 9 o'clock.
4. The opposite of must is need not.
Mum, must I wash up? - No, you needn't. I've already done it.
Must not has a different meaning. It is used to express prohibition that involves the speaker's will.
We mustn't come late today. Or the teacher will be very angry.
He mustn't enter this room. It is dangerous.
Note
Normally, these modal verbs are not used in different tenses. The past tense of can is could, the modal verbs may and must, however, only have the present form. All the other tenses must be formed in a different way.

We make the passive voice with a modal verb + be + past participle: This can be done. The laws must be respected.
Do' for General Ideas
Use the verb 'do' when speaking about things in general. In other words, when we do not exactly name an activity. This form is often used with the words 'something, nothing, anything, everything, etc.'
I'm not doing anything today.
He does everything for his mother.
She's doing nothing at the moment.

Important Expressions with 'Do'
There are a number of standard expressions that take the verb 'do'. These are standard collocations (verb + noun combinations) that are used in English.
do one's best
do good
do harm
do a favour
do business

'Make' for Constructing, Building, Creating
Use 'make' to express an activity that creates something that you can touch.
make food
make a cup of tea / coffee
make a mess

Important Expressions with 'Make'
There are a number of standard expressions that take the verb 'make'. In a number of cases the verb 'do' seems more appropriate. These are standard collocations (verb + noun combinations) that are used in English.

make a telephone call

Active / Passive Verb Forms
Sentences can be active or passive. Therefore, tenses also have "active forms" and "passive forms." You must learn to recognize the difference to successfully speak English.
Active Form
In active sentences, the thing doing the action is the subject of the sentence and the thing receiving the action is the object. Most sentences are active.
[Thing doing action] + [verb] + [thing receiving action]
Examples:

Passive Form
In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action.
[Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action]
Examples:

Present perfect with superlative forms of adjectives

Tags:
emphasis
perfect
present
superlatives

The present perfect tense is often used with superlative forms of adjectives to express emphasis.

This is the first time I have been to Prague.
This is the worst film I have ever seen.

This use also applies to the past perfect tense.

Jill was the most beautiful girl John had ever met.

This sentence means that until that time John had never met such a beautiful girl. It also implies that he has since then. If, however, poor John hasn't met anybody like her since then, we use the present perfect:

Jill was the most beautiful girl John has ever met.

With future tenses (this will be...) we use the present simple tense in such structures.

This will be the last time that I buy you a tram ticket.

O Present Continuous é utilizado para expressar ações no presente, as quais acontecem no momento em que se fala, para indicar eventos futuros que tenham sido planejados e confirmados ou ainda para expressar certeza de que algo irá acontecer.

Em português, o gerúndio tem a seguinte terminação –ndo, como por exemplo: Eu estou caminhando agora. No inglês, forma-se com a conjugação do verbo to be (am/is/are) + o verbo principal com a terminação –ing. Ele geralmente acompanha advérbios de tempo: now (agora), at present (no presente), at the moment (no momento) e etc.

Observe o verbo to speak:
Pronome

Verbo to be

Verbo no gerúndio

I

am

Speaking


You

are


He

is


She


It


We


are


You


They


O verbo to be pode ser abreviado. As abreviações são utilizadas na fala, visto que é informal fazer abreviações. Na escrita, dispensam-se abreviações. Observe:

Pronome

Verbo to be

I

'm


You

're


He

's


She


It


We


're


You


They
Para transformar um verbo em Present Continuous, a adição do –ing, há que se observar algumas regras:
VERBOS TERMINADOS EM –E: retira-se o –e e acrescenta-se –ing

Change (mudar):changing

live (viver): living

EXCEÇÕES:

Be (ser, estar): being

lie (mentir): lying

Ex.: I am having dinner now. (Eu estou jantando agora.)
You are lying. (Você está mentindo.)
VERBOS DE UMA SÍLABA (OU DUAS, DESDE QUE A ÚLTIMA SEJA TÔNICA, TERMINADOS NA SEQUÊNCIA CONSOANTE-VOGAL-CONSOANTE): dobra-se a última letra e acrescenta-se –ing

run (correr): running

stop (parar): stopping

Ex.: Sarah is running very fast. (Sarah está correndo muito rápido.)
He is stopping at the corner. (Ele está parando na esquina.)

Obs.: Em inglês britânico, dobra-se a consoante L => travel (viajar): travelling

EXCEÇÃO: Não se dobram as consoantes w e x:

Snow (nevar): snowing

fix (arrumar): fixing

MAS CASO A SÍLABA TÔNICA SEJA A PRIMEIRA: somente acrescenta-se –ing

open (abrir): opening

happen (acontecer): happening

VERBOS TERMINADOS EM –Y: acrescenta-se –ing

play (jogar): playing

say (dizer): saying

Ex.: Wait! I am playing video game. (Espere! Eu estou jogando videogame.)
Look! He is saying something. (Olhe! Ele está dizendo alguma coisa.)

try (tentar): trying

cry (chorar): crying

Ex.: This exercise is difficult. I’m trying to do it. (Esse exercício é difícil. Eu estou tentando fazê-lo.)
Oh my God, she is crying. (Ô meu Deus, ela está chorando.)

VERBOS TERMINADOS EM –IE: troca-se o –ie por –y e acrescenta-se –ing

lie (mentir): lying

die (morrer): dying

Ex.: She is lying to me. (Ela está mentindo para mim.)
I’m dying. (Eu estou morrendo.)


HAS BEEN' = present perfect - tempo verbal que não existe em português.
Portanto, o melhor é saber usar e não entender.
Usos mais prováveis para quem se 'inicia no uso' do present perfect:

- He has been my best friend for years. ==> usei HAS BEEN porque literalmente 'ele tem sido meu amigo por anos' ou 'ele É meu amigo há anos'
==> essa ação não teve fim, começou em algum momento no passado e segue até hoje ==> TÍPICO DE PRESENT PERFECT: um passado que ainda se manifesta no presente.

- It's been a long time we don't see each other. ==> faz muito tempo que não nos vemos ==>
- It's been a long time I don't see my mother. ==> faz muito tempo que não vejo minha mãe
==> sempre que quiser usar essa expressão de tempo em português, use do jeito que escrevi em inglês, em 'contraction' mesmo.
==> sem a 'contraction' seria 'It has been a long time...' mas é 99% de uso com 'contraction'.

- She's been in the USA for a long time. ==> ela está nos EUA há muito tempo
==> essa ação não teve fim, começou em algum momento no passado e segue até hoje.

Bom, tô sem idéias para acrescentar, mas se vc pegar o jeito para usar essas 2 idéias, já caminhou bem no present perfect. Aí, num outro dia falamos de outra situação de present perfect.
