Don't you understand verbs in English?

If you need to add another verb after the verb, you should analyze the function of the verb after it in the sentence and make different deformations. There are roughly several situations: 1, connected by conjunctions, then the first verb is as important as the last verb. 2. The last verb becomes infinitive. 3. The last verb becomes present participle or past participle. 4. The latter becomes a gerund. The deformation of verbs is very complicated and it is a very important grammar.
