To which verb is the indefinite form (Cm) incorrectly selected?
When forming the forms of the verb, it is necessary to ensure that its constant features, in particular the form, do not change. If the appearance has changed, you have formed the verb form incorrectly. In these words, such a mistake was made in the pair "save - save", where the first verb is perfect (what will I do?), The second is imperfect (what should I do?). The initial form in this case will be the verb "to save".
To the third pair the indefinite form of verbs is chosen incorrectly. You can start checking over and see this:
- what will they do? - carried - what to do? - attributed - right;
- what are they doing? - refer - what to do? - refer - true;
- what to do? - to save - what to do? - to rescue - wrong;
- what will they do? - will be invited - what to do? - to invite - right.
