To studying verbs, including its uncertain form, school students start in initial classes. If material is acquired badly, spelling errors "тся" and "ться" are possible. Therefore the teacher needs to pay their attention to identification signs of an infinitive.
Instruction
1. You have to know that the uncertain form of a verb is often called an infinitive. The verb in such form does not change neither on numbers, nor on persons. It is impossible to define at it both an inclination, and a look.
2. It is possible to form, of course, an uncertain form of a verb by means of the auxiliary questions "what to do?", "what to make?". But such way not always can you useful. So, to school students difficult happens to put impersonal verbs in an infinitive that can turn out to be further consequence of spelling errors.
3. Children also confuse verbs in the form of the third party with an infinitive, so, will not be able to define how it is correct to write: "тся" or "ться". For example, to a verb in a syntactic design "it seems successful" children find it difficult to raise the auxiliary questions "what to do?", "what to make?". Thus, they will not be able to check writing of a word.
4. To find an uncertain form of a verb or to form it simpler, paying attention to some details. So, you have to know that the infinitive has the termination "t" or "ti". For example, in the word "bring" the termination will be "ти", and in the word "be in time" - "ть".
5. The termination "ti" is written in an uncertain form if before it there is a vowel, and "ть" - after concordant. So, in an infinitive it is worth "blossoming" before the termination "ti" a consonant "with", and in the word "see" - public "е".
6. The verb in an uncertain form can also terminate on "чь". But in this case "чь" will not be the termination, and will be a part of a root. It can be seen, having changed a word form: to protect - protects. You see that in a root there is a sound interchange.
7. To learn to form an uncertain form without mistakes, it is necessary to raise the questions "what to do?" or "what to make?" and not to forget to pay attention to the structure of a word.
