Input: Consider Input: Person1: What do you think is harder , reading or writing ?
Person2: Well , they ' re completely different . Reading is passive , and writing is active .
Person1: I don ' t think I understand what you mean . Could you explain a little more ?
Person2: In reading you need to recognize language by seeing the words on the page and knowing what they are . In writing you have to produce language , you have to create your own words on a blank page .
Person1: Oh , now I see what you mean . When you ' re reading , you are just looking , but when you are writing , you are actually doing something !
Person2: A reading knowledge of a language is larger and different from a writing knowledge . Don ' t you think so ?
Person1: I think I see what you mean . I can read Shakespeare but I definitely can ' t write it .
Person2: Exactly .
Person1: So I have another question for you . What do you think is harder , speaking or understanding ?
Person2: They ' re both harder than reading or writing .
Person1: In what way ?
Person2: Because they are direct communication with another person , and there ' s a time limit . This time limit is the most serious problem for foreigners , even for those who know lots of English .
Person1: You are making me feel really discouraged .
Person2: I ' m not trying to discourage you . I ' m trying to help you . You have to live with these difficulties . Isn ' t it better to know about them ? The more you know about what you have to face , the better you ' ll do . I promise !
