Analysis of Causes of the Formation of English Negative Sentences by Our Middle School Students

The study of acquisition of negative sentences is an important means in the research of second language acquisition. Overseas research shows that in the second language acquisition process, there are certain laws that govern how people form negative sentences; however, these laws have not been effectively applied in English learning of our students.
