Description

Fort Leavenworth, Kansas. — 16 p. (Автор и год издания не указаны).This programmed learning material will teach you some of the basic concepts regarding verb forms and tense. Most frames require a response; the correct answer is in a box at the beginning of the next frame. In English verbs have three main forms or principal parts. We mention a fourth form in frame 24 of this instruction, but we will concentrate on the three main forms.
