Besides,  Langan  1996  adds  if  subjects in  a  sentence  are joined  by and, they would be followed by a plural verb p. 340. The examples are:
[14] Desya, Clarina, and Rio are very smart students in the class. [15] The shirt, the skirt, and the hat are new.
In  addition,  Greenbaum  1989  states  if and is  not present  in  a  sentence,  the subject is still decided as plural p. 211.
[16] Desya, Clarina, Rio are very smart students in the class. [17] The shirt, the skirt, the hat are new.
However, Greenbaum  1989  also  states  if  the noun  phrases  are  introduced  by every or each, the subjects are considered singular p. 211.
[18] Every man and every woman has the same right. [19] Each girl and each boy in the seventh-grade is a great student.

According  to Leech  and Svartvik 1994, in  the  present  tense  there  are
three be as  the form, they  are I am I  am  a  student, HeSheIt is She  is  very beautiful, WeYouThey are You are a dentist p. 264. In a sentence, be form is
not  only  has  the  present  tense form,  but  also  it  has eight different  forms  in common. They are am, is, are, was, were, being, and been. These be forms are
used in every sentence based on the tense that is used. Leech and Svartvik made a table  that  would  help  students  to  learn  easily.  In the  table 2.1. below shows the
forms of be which is proposed by Leech and Svartvik 1994.

Then, according to Leech and Svartvik 1994, main verbs have only two forms in the present tense p. 264, for example,
[20] Hesheour friend etc. likes cooking [21] Iyouwetheyour friends etc. like cooking
Sentence [20] shows the 3
rd
person singular subject, while sentence [21] does not show the 3
rd
person singular subject. Leech and Svartvik 1994 also  add that modal  auxiliaries only  have one
form p.  264.  It  means  that  modal  auxiliaries  cannot  be  added  by –s form, -ing form, or –ed participle, for example,
[22] Iweyouhesheour friendour friends etc. will cook dinner today.
