It was found that there are 191 sentences from the six selected text in the textbook consisting of the simple sentence which has 53 sentences (27,75%), the compound sentence has 79 sentences (41,36%), the complex sentence has 33 sentences (17,27% ) and the compound-complex sentence has 26 sentences (13,61%) from the total number of the data. The finding of the analysis shows that the English textbook has all types of sentences, based on both several clauses and their syntactic properties.
