As mentioned previously in move 1, usually when we need to give the general picture of the related topic, we can use simple present tense or present perfect tense to indicate the current situation or the problem persisting up to the present time. Moreover, some adjectives are also necessary to indicate the importance or the necessity of conducting the proposed research. Here are some examples of expressions used in giving big pictures:
-

-

-

In order to state the gaps of the research, we can use some words to express a contrasting viewpoint, a critical evaluation of gaps in the literature, or a perceived weakness in prior research. Some words are presented in Table 4.2.
When put into sentences, the examples are as shown below:
-

-

-

-

-

-
