"Data Collection To run this study, which is a corporal analysis of comparison forms in Iranian high schools and English course books as well, the most necessary material was the corpus firstly composed of four versions, 1 to 4, of the series The Right Path to English (Birjandi, 1376).
Interchange series (Richards, 2005), including 6 books of different levels cov- ering all four skills of learning, which is offered to students who have an interest in learning English as a foreign language, are the second major part of the above mentioned corpus.
The first phase included computing the frequency of occurrence for each and every comparative structure via the software both in high school books and Interchang- es; followed by phase two which involved calculating the percentage of occur- rence for the elicited forms in phase one.
As mentioned previously, English books taught in high school were scanned and further changed into computerized format in order to be investigated and compared to those not written by Iranian non-native material developers.
2) Frequency Percentage of Comparatives in Interchange books / Similar to the high school books, progressive forms, sentence connectors and oth- er forms of comparison have not been covered in the beginning levels.
Likewise, it can be seen in the tables that in the second level that is the sec- ond year in high school and the elementary level in Interchange books juxtaposi- tions have been utilized the most, while the difference between the two groups lied in the distribution of the forms."
