This paper carries out a quantificational analysis upon the corpora of the english learners from primary schools to universities, especially middle schools, and makes comparisons in longitude and latitude. we find out from the comparisons that the language items puzzling the students most are : omission / addition of " ~ s " after third person singular verbs, omission / addition of " be ", error of tenses, error of articles, error of preposition collocations, agreement of subjects and verbs, error of singular / plural nouns, error of infinitives, error of part of speeches, error of possessive cases, empty of conjunctions in coordinative sentences, error of spellings ; elementary or intermediate learners ( such as freshmen ) suffer from native language transfer or simplification a lot ; advanced learners ( such as sophomores ) are affected by the overgeneralization of target language ; the error of part of speech or semantic selection ( except conceptual meaning ) runs through all phases, and it is likely to be fossilized
