In this study, the Reviewing stage took place both while sentences and after writing finishing the written text; in other words, the subjects would go back and forth between the Translating Stage and the Reviewing Stage. Thus, some strategies, such as rehearsing and self questioning, could occur in these two or three stages (see Table 4.4); especially in self questioning, in this study, which the subjects used as their monitor phase during e-mailing, which can confirm the writing model of Flower and Hayes (see Figure 2.1)
