Connecting nouns with "shi"
The verb to be is not used in Chinese the same way as it is in English. In Chinese, 是 is for connecting nouns, and is generally not used with adjectives.
Structure
The structure for connecting nouns with 是 is:
Noun 1 + 是 + Noun 2
This is equivalent to "Noun 1 is Noun 2" in English. In terms of sentence elements, the structure is:
Subject + 是 + Object
Chinese does not conjugate verbs. That is, the form of the verb is the same no matter who is doing it. In this case, it is always 是 and never changes. As you can see, it's easy to form simple sentences expressing to be in Chinese.
