class_docstr: Adding the Meaningless sentences to the hypothesis and remain both premise
  and label.
  Users can use their own meaningless sentences by change the text in
  transform method
  
  exmaple:
  {
      hypothesis: I hate this book.
      premise: This book is my favorite. today is Monday.
      y: contradiction
  }
docstr: Transform text string, this kind of transformation can only produce one
  sample.
  
  :param ~NLISample sample: input data, a NLISample contains 'hypothesis'
      field, 'premise' field and 'y' field
  :param int n: number of generated samples, this transformation can only
      generate one sample
  :return list trans_samples: transformed sample list that only contain
      one sample
