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.
