2. Health and fitness.
Modal verbs in English are notobey the general rules on which other verbs act. They are not used separately and do not have independent meaning. Modal verbs "can", "could", "must", "may" express the speaker's attitude to the main action. What does it mean? Some verbs express the degree of possibility, others - an obligation. After modal verbs, the "-to" particle is not used, with the exception of the verbs "to be able to" and "manage to". Examples:
I can swim. (I can swim).
She must obey her parents. (She must obey the parents).
Who could see my cat? (Who could see my cat?).
Workers are not able to finish this building. (Workers are not able to complete the construction of this building).
She managed to find her mobile phone immidiately when we went away. (She was able to find her mobile phone, right after we left).
Rules for the use of modal verbs
As already mentioned above, modal verbs exist according to their own rules. But they are easy to remember, since the list of such verbs is small:
- to be able to - can;
- manage to - can;
- can / could - can, could;
- must - must;
- may - can.
As you can see, some of them havesynonymous meaning. There is a common misconception that the modal verbs "can", "could", "must" and "may" vary in persons and numbers, in time. In fact, this is not so. That is, we do not add any endings to these verbs and do not change them. The exception is the verb "manage" - we can put it in the past tense by adding the ending "-ed" - "managed". And also, the verb "to be able to" - here the auxiliary verb "to be" changes according to general rules.
The verbs "to be able to" and "manage to"
The verb "to be able to" translates as "to be able, able, able". For example:
These people are able to do the work in time. (These people are able to do the work on time).
The verbs "can" and "could"
The next rule is more complicated, but not much. The modal verbs "can" and "could" are translated as "can, can", have a common meaning. While "manage to" and "to be able to" are used, mostly, in special cases. Although, only mostly. In principle, the verbs "can", "could", "managed", "be able to" act according to similar rules.

Nowadays	Past tense	Future tense*
I can (I can)	I could (I could)	I will be able to (I can)
He can (He can)	He could (He could)	He will be able to (He can)
She can (She can)	She could (She could)	She will be able to (She s) can
They can (They can)	They could (They could)	They will be able to (They can)
We can (We can)	We could (We could)	We will be able to (We can)
You can (You can / You can)	You could (You could / You could)	You will be able to (You can / You can)

he verbs "must" and "may"

The next moment. The verbs "can", "could", "must", "may" have separate forms at different times. This simplifies their use. The verb "must" has the sharpest degree of obligation. For example:
You must go home now, it won "t be discussed! (You must go home and this is not discussed!).

If you want to use a softer degree of obligation, give advice or recommendation, then the "should" verb should be used. For example:

You should not eat so much sweet, if you want to be fit. (You should not eat so much sweet, if you want to be slim).
The verb "may" is translated as "can" and, usually. is used in polite requests. For example:

Nowadays	Past tense	Future tense
I must (I must)	I have to (I should have)	I will have to (I'll have to)
He must (He should)	He has to (He should have)	He will have to (He will)
She must (She should)	She has to (She should have)	She will have to (She will have to)
They must (They must)	They have to (They should have been)	They will have to (They will have to)
We must (We must)	We have to (We should have)	We will have to (we will)
You must (You must / You must)	You have to (You should have / You should have)	You will have to (You must / You will)

(I'm sorry, can I take your pen for a minute?).
The verb "must" does not have forms in other times, except for the present. Therefore, we substitute analogous values. In this case it is appropriate to use modal the verb "have to" "I must, I must."
The use of modal verbs in negative and interrogative sentences
The order of words in English sentences is strictlyfixed. This means that, regardless of the context, in the affirmative sentence the first place will be the subject, then the predicate, then the additional members of the sentence. In the negative sentence - all the same. Only after the predicate there is a negative particle "not". This order of words is called direct. The word order in the interrogative sentence is called the reverse. Here, at the beginning of the sentence is a predicate, then - the subject, then - additional members of the sentence. In the case of the modal verbs "can", "could", "may" and others, everything is according to the rules. They function as auxiliary. For example:
I can not swim.
She must not do it, if she does not wont. (She should not do this if she does not want to).
(She can not cook dinner without light).
Can you help me with the dinner? (Can you help me with dinner?).
Shall I go with her? (Should I go with her?).
May I go for a walk, I'm tired. (I can go for a walk, I'm tired.).
In special interrogative sentences the question words are at the beginning of the sentence:
Who can speak English? (Who can speak English?).
