【Skill 5】Understand the difference between the two things from the expressions that are reversed in form
Understand the difference between the two things from the expressions that follow は（a form showing contrast）, 場合（the case）, and ほうは（a form showing contrast） are reversed in form, as in affirmation and negation.
In the following recording, negation form as in 著作物にあたらない（is not copyrighted work） and affirmation form as in 著作物にあたる（is copyrighted work） that follow は（a form showing contrast） are used, which explains the difference between アイデア（idea） and 小説（novel） that precede は（a form showing contrast）.
■ アイデアは著作物にあたらないのに対して、小説は著作物にあたります（Ideas are not copyrighted works, whereas novels are）
